Can You Train With a Dislocated Shoulder? The Traumatic-Instability Audit: Where the Emergency-Room Census Counts 23.9 Dislocations per 100,000 Person-Years and Nearly Half Happen in Sport; Where the Lesion Door Reads 97% Perthes-Bankart Avulsions in Young First-Time Dislocators — and 90% of Them Recurred Without Surgery; Where the Age Gradient Runs 93% Recurrence at 14–18 Against 40% at Thirteen and Under; Where the Bone Bill Charges 6.8% of Glenoid Width Per Instability Event and Every Recurrent Shoulder Crossed the 20% Line; Where Hovelius's Twenty-Five-Year Swedes Answered the Sling Question Twice — 43% Never Redislocated and Immobilization Changed Nothing; Where the Randomized File Prices Repair at 6.3% Against 46.6% Recurrence and Sent Contact Athletes Back to Their Sport 3.4× More Often; and the In-Season Door Returned 26 of 30 Athletes in 10.2 Days at the Price of 37% Repeat Episodes: the Dislocated Shoulder's Medicine Is Naming the First Time From the Habit, Billing the Bone, and Training Everything the Arm Doesn't Take to the End-Range

There is a fence at the top of this post and it outranks everything below it: a shoulder that is still out, a first-time dislocation that cannot be gently reduced on the field, or any dislocation arriving with a cold, pulseless or persistently numb arm is the emergency door — an emergency department today, not a training question. The second fence: weakness that does not clear as the pain settles, or a deltoid that stays numb, is the nerve door — examined this week, because 45% of first dislocations carry electrophysiological evidence of nerve injury, most of it recovering inside four months, but watched by someone who knows the difference [20]. The third: a dislocation with a fracture on the film — greater tuberosity, glenoid rim, surgical neck — is the X-ray door first and the program second; the irony the 25-year file adds is that a tuberosity fracture actually protected against recurrence (2 of 24 redislocated), but the bone still needs its own clearance before load [6]. The fourth: a first dislocation at forty-plus is a different dossier — in the older shoulder the cuff is the tissue that pays, and that audit lives in the rotator-cuff-tear guide. The fifth, and the one this file exists to police: a shoulder that dislocates at the bottom of a bench press or the catch of a clean — effortlessly, repeatedly, sometimes on request — has crossed from "injury" into "instability with bone loss," and every additional episode is re-pricing the surgical bill [4][16]. With the fences respected, the question underneath splits into the two scripts this injury-family library keeps convicting in opposite directions: the shut-it-down script ("it's out, sling it for six weeks, don't move it, hope it heals") and the pop-it-back script ("it went back in, I finished the session"). The first prescribes the exact stillness two prospective decades of Swedish data priced at zero effect on recurrence [5][6]; the second ignores that each instability event bills the glenoid 6.8% of its width, and that every recurrent shoulder in the prospective cohort crossed the 20% bone-loss line where soft-tissue repair stops working [4][16]. The evidence, from a 1994 Dutch EMG ward to a 2026 adolescent return-to-play review, rejects both, with numbers [20][19].

The short answer: train — everything the arm doesn't take to end-range abduction and external rotation, from the first week, while the file gets named (first time or habitual, young or older, bone stock intact or billed), the sling religion gets retired, and the young contact athlete books the consult the randomized trials priced

Strip the file to its spine. The first dislocation is almost never a bruise: of 63 young first-time dislocators scoped within ten days, 97% had the capsulolabral complex detached from the glenoid — the Perthes-Bankart lesion — and 90% of their nonoperatively treated teammates recurred [3]. Recurrence is a young person's tax: 90% under 24 at West Point [3], 93% in 14-to-18-year-olds against 40% at thirteen and under [7], and in the ten-year Swedish cohort, recurrence severe enough to need surgery ran in 34% of the 12–22-year-olds against 9% of the 30–40s [5]. But half of non-surgical shoulders never make the taxman's list: 52% had no recurrence at all at ten years [5], 43% never redislocated and another 14.4% stopped recurring on their own by twenty-five [6], and the network meta-analysis of 22 randomized trials states it flatly — with non-surgical management, 47% did not redislocate [15]. Immobilization is not a treatment: neither its type nor its duration changed recurrence in the ten-year cohort [5], it did not change the prognosis at twenty-five [6], and the 2026 meta-analysis of 17 studies and 1,170 patients closed the external-rotation-brace door the 2003 study had opened — no difference in recurrence, return to sport or apprehension [9][10]. What rehabilitation can do is real but old and small: the midshipmen program — internal-rotator and adductor strengthening through isometrics to isokinetics, activity restricted until goals met — held recurrence to 25% against a historical 50–94% [8]. Surgery is the priced door for the young contact athlete: across the five level-1 randomized trials, recurrent instability ran 6.3% after stabilization against 46.6% in slings, subsequent stabilization surgery 4.0% against 30.8% [14]; the double-blind trial cut redislocation risk 76% and sent contact athletes back to sport 3.4 times more often [12]; and the edge held at 14.2 years — 12% versus 47% [13]. The bone bill decides which surgery: arthroscopic repair recurred in 4% of shoulders without bone defects and 89% of contact athletes with them — while the Latarjet bone block held the same desperate shoulders at 4.9% [16][17]. Train everything that keeps the arm out of the abducted-externally-rotated corner; name the file before you program it; and let the age band, the sport and the bone stock — not fear, and not bravado — pick the door [3][4][14][16].

Who is asking: the scale file

The shoulder is the joint the body dislocates most, and it does its dislocating young and in public. The census: 8,940 dislocations through American emergency departments in five years — 23.9 per 100,000 person-years, twice the previously reported rate — with 71.8% in males, peak incidence in the twenties (47.8 per 100,000 at ages 20–29), 46.8% of all dislocations between fifteen and twenty-nine, and 48.3% occurring during sports or recreation; most of the rest were falls, mostly at home [1]. The athlete census is louder: among 4,141 cadets at the United States Military Academy watched prospectively for one year, 117 suffered new traumatic instability events — a 2.8% one-year incidence in a healthy young population — and here is the naming inversion that opens this whole file: 84.6% of those events were subluxations, not dislocations [2]. The shoulder mostly starts to come out and slams back; only one in seven events completed the trip [2]. That matters for the lifter holding a shoulder that "almost came out" on a press: the partial event is the same address, the same mechanism, the same lesion spectrum — and the same file [2][3]. Direction matters too: 80.3% of the events were anterior [2], and this audit owns the anterior file — the ABER address (abduction plus external rotation) that the bench press bottom, the overhead catch, the volleyball swing and the jiujitsu underhook all visit. The posterior file is its own rarer audit, usually the seizure, the fall-on-outstretched-hand or the electrical-injury file, and the multidirectional painless laxity file belongs to the hypermobile population, not this one.

The mechanism door: the abducted-externally-rotated address

Every audit family has a mechanism file, and this one is the most mechanical of them all: the glenohumeral joint trades bony containment for range — a golf ball on a tee — and the price is that in the abducted, externally rotated position the anterior capsule, the labrum and the inferior glenohumeral ligament are the only things holding the ball in the socket [3]. When the arm is forced past that corner — the arm-wrestling explosion, the missed punch, the bar caught behind the head, the arm planted and the body rotating over it — the anterior structures either hold or they avulse. The lesion door is unambiguous about what usually gives: scoped within ten days, 97% of young first-time dislocators had the capsulolabral complex torn off the glenoid rim (the Perthes-Bankart lesion), 57 of 63 carried Hill-Sachs indentations on the back of the humeral head (none large), and not one had a rotator-cuff tear — in a mean-19.6-year-old population, the cuff is not the tissue that pays [3]. A dent in the bone and a labrum off the rim is the standard bill. And the mechanism is the program in both directions: everything in training that avoids the end-range ABER corner spares the injured corner, and everything that rehearses it — behind-the-neck presses, deep dips with elbows flared, the low-elbow bottom of a sloppy bench, bar-path-drifting overhead work — re-runs the mechanism that caused the file. The 43.6% of cadet injuries from contact and 41.0% from noncontact mechanisms say the same thing twice: the address is loaded by sport and by the weight room alike [2].

The bone-bill door: why "walk it off and finish the session" is an installment plan

This is the door where the modern evidence is most unforgiving, and it converts every recurrence from a "pop it back and continue" event into an arithmetic event. The prospective West Point cohort measured glenoid bone on baseline and post-injury MRI in 714 athletes: a single instability event costs 1.84 millimeters — 6.8% of glenoid width — of bone, with 52% of first-time shoulders already at ≥5% loss [4]. A first event never crossed 20%; the shoulders that came in with a history (mean preexisting loss 10.2%) and then sustained one more measured event left at 22.8%, and every single recurrent shoulder in the cohort — six of six — crossed the 20% line [4]. Twenty percent is not an arbitrary number: it is the neighborhood where the Burkhart file found soft-tissue repair stops holding, where the glenoid runs out of anterior bone for the labrum to be repaired onto, and where the conversation changes from Bankart to Latarjet [16][17]. This is the audit's cleanest sentence against the pop-it-back script: each extra dislocation is not a repeat of the last injury, it is a compounding one — the second episode operates on a glenoid the first episode already shortened [4]. The lifter's translation: the first dislocation is an injury; the decision about the second one is a surgical decision, because the data say the third arrives with a different glenoid [4][16].

The age file: recurrence is a young person's tax — and the calm half nobody quotes

Two files bracket the prognosis, and the audit needs both. The tax file: 90% of the under-24 cadets treated nonoperatively recurred [3]; the children's meta-analysis pooled recurrence at 73% in ≤18-year-olds, with 14-to-18-year-olds recurring at 93% against 40% for thirteen-and-unders (odds ratio 24) and closed physises multiplying risk 14-fold [7]; and in the ten-year Swedish cohort, recurrent dislocation needing surgery developed in 34% of the 12–22-year-olds, 28% of the 23–29s, and 9% of the 30–40s [5]. The calm file: the same ten-year cohort — 247 primary dislocations at twenty-seven hospitals — recorded no further dislocation at all in 52% of shoulders [5]; at twenty-five years, 43% had never redislocated, another 7% exactly once, and 33 shoulders that had recurred early stabilized spontaneously over time (14.4%) [6]; and the network meta-analysis of 22 randomized trials carried the number into the evidence hierarchy: with non-surgical management, 47% did not redislocate [15]. These are the same population. The reconciliation is the age band, the sport, and the skeleton: the 16-year-old rugby contact athlete and the 38-year-old recreational lifter hold the same diagnosis with almost opposite prognoses [5][7]. The practical consequence is symmetric honesty: the young contact athlete should not be reassured by the calm half, and the older recreational lifter should not be terrorized by the tax half — the file is named by age band and mechanism before any program is written [5][6][7].

The sling religion: retired twice, in two decades, in the same cohort

What to do with the arm while the file gets named is where folk medicine is strongest, and where the prospective evidence is flattest. The ten-year Swedish cohort randomized-by-practice its initial management — torso strapping for three to four weeks, a sling abandoned at comfort, or mixed durations — and found "the type and duration of the initial treatment had no effect on the rate of recurrence" [5]. Twenty-five years later the same cohort said it again: "immobilization after the primary dislocation did not change the prognosis" [6]. Then came the elegant biomechanical idea — the labrum lies better approximated with the arm in external rotation — and the 2003 preliminary study that lit the market: recurrence 30% in the internal-rotation sling versus 0% in the external-rotation brace at 15.5 months, and 45% versus 0% in the under-30s [9]. It took two decades of trials for the 2026 meta-analysis to close the door: 17 studies, 1,170 patients, no difference between external and internal rotation in recurrence (P=.41), Constant score (P=.15), return to sport (P=.12) or apprehension (P=.22) — the single significant WOSI difference was 2 points, below the threshold of clinical importance, and the authors' conclusion reads "routine use of ER bracing may not be warranted" [10]. The pattern is one this library keeps meeting (the colete file in the spine audit ran the same arc): a real biomechanical observation, a promising early series, and a null verdict at scale. What the sling is for: comfort in the first days, and keeping the reflexive arm out of the injured corner. What it is not: a healing machine for a labrum that tore off bone [5][6][9][10].

The rehab door: the midshipmen file, and what "rehabilitation" actually meant

The nonoperative file has exactly one classic that quotes a number below the noise, and it deserves to be read precisely because of how demanding it was. Twenty Naval Academy midshipmen, first-time dislocators, all run through one rigid program: restrengthening emphasizing the internal rotators and adductors — the exact muscles that pull the arm out of the dangerous corner — progressing from isometrics through isotonics to isokinetics, with activities restricted until the program's goals were met, then return to full duty including the sport that caused the dislocation [8]. Result: five recurrences in twenty shoulders — 25% at a mean 35.8 months, against the 50–94% recurrence the same paper catalogued in the literature [8]. The honest reading is not "rehab cuts recurrence to a quarter." It is that supervised, sport-specific, goal-gated rehabilitation with real activity restriction is a treatment, and three weeks in a sling followed by hope is not — the 47%-never-redislocate figure in the network meta-analysis belongs to physiotherapy programs, not to stillness [15]. What trains in the modern version: scapular control, internal-rotation and adduction strength (the midshipmen's own emphasis), rotator-cuff endurance, and progressive exposure back into the corner — dosed by the 24-hour pain budget this family's files always use. The old file and the new trials agree on the mechanism if not the magnitude: the muscles that keep the arm out of the ABER corner are trainable, and the program is the cheapest door in the building [8][15].

The surgery door, told honestly: what the randomized trials actually bought, and for whom

The randomized file on first-time dislocation is one of the deepest in sports medicine, and it deserves a straight reading. The first trial: 40 patients under 30, immediate arthroscopic stabilization versus immobilization — redislocation 15.9% versus 47% at 24 months (P=.03), disease-specific quality of life better in the surgical arm [11]. The placebo-controlled trial — the one that answers "is it just the cleanup?": 88 patients 35 and under randomized to arthroscopic lavage alone or lavage plus Bankart repair, double-blind — repair reduced further dislocation risk by 76% and all recurrent instability by 82%, cost less (P=.012), satisfaction higher (P<.001), and contact-sport players were 3.4 times more likely to have returned to their sport at two years (RR 3.4, P=.007) [12]. The fourteen-year follow-through: the same trial at mean 14.2 years — redislocation 12% versus 47% (P=.002), event-free survival 79% versus 58% at ten years, WOSI still better — the edge does not fade [13]. The meta-analysis of the five level-1 trials: recurrent instability 6.3% versus 46.6% (P<.00001) and subsequent stabilization surgery 4.0% versus 30.8% (P<.00001) at a mean 59.7 months [14]. Now the honest half, because the network meta-analysis insists on it: with non-surgical management 47% never redislocate [15]; half of young Swedish shoulders were stable or had stabilized by twenty-five years without any operation [6]; and the surgery door is not free — it is an operation with capsular restriction, a rehabilitation ladder measured in months, and a recurrence file of its own that depends entirely on the bone bill [16][17]. The reconciliation the data support: the younger the athlete, the more contact the sport, and the more the season matters, the more the randomized numbers point at early repair — that is the population the trials were run on, and the population the 3.4× return-to-sport number describes [11][12][14]. The older the patient and the more recreational the load, the more legitimate the rehabilitation-first door becomes — priced, not default [6][15].

The bone-loss door: the 89% number, and the graft that answered it

The 2000 Burkhart-De Beer series is the door that reorganized the field, and its numbers still structure every surgical conversation. One hundred ninety-four arthroscopic Bankart repairs, 101 of them in contact athletes (96 South African rugby players): overall recurrence was 4% in the 173 shoulders without significant bone defects — 6.5% even in contact athletes without defects — but 67% in the 21 shoulders with an "inverted-pear" glenoid or an engaging Hill-Sachs lesion, and 89% in contact athletes with those defects [16]. The lesson is not "surgery fails"; it is which surgery: arthroscopic soft-tissue repair assumes a glenoid with enough rim to repair onto, and a humeral head without a dent that engages the rim in the provocative corner. When the bone is gone, the door is the bone block. The same group's 102 patients with ≥25% glenoid bone loss — median six dislocations before surgery, twenty of them with more than fifteen — underwent the modified Latarjet: 4.9% recurrence at a mean 59 months, Constant score 94.4, forward elevation preserved, five degrees of external rotation paid [17]. Put beside the prospective bone-bill file, the two doors close into one program: measure the bone before choosing the surgery, because the glenoid's arithmetic — 6.8% per event, 20% as the soft-tissue line, every recurrent shoulder in the cohort over it — is what decides whether the labrum can be repaired or the socket must be rebuilt [4][16][17]. And run in reverse, the same arithmetic is the strongest prevention file in this audit: preventing the second dislocation is not pain management, it is keeping the surgical menu open [4][16].

The in-season door: 10.2 days, and the 37% price

The question the in-season athlete actually asks is not "surgery or sling" but "can I finish the season," and the Buss file answers it with the most honestly-priced numbers in this literature. Thirty in-season athletes with anterior instability — 19 dislocations, 11 subluxations — treated with rehabilitation and bracing where appropriate: 26 of 30 returned and completed their seasons, at a mean 10.2 days missed; 10 of the 30 (37%) sustained at least one further instability episode during the season, averaging 1.4 episodes per athlete-season; no additional injuries attributable to playing through; and 16 elected surgical stabilization in the off-season [18]. The return-to-play file completes it: across 25 studies and 1,172 adolescent athletes, 66–100% returned to play after arthroscopic Bankart repair, 88–100% after open repair, and 72–94% after Latarjet — high rates through every door — with Latarjet carrying the lowest recurrence (0–8%) but the same-or-higher-level return lagging behind (70–81%) [19]. The in-season program the numbers describe: rehabilitate immediately, brace the corner, accept a real and quantified risk of an in-season repeat, and book the off-season for the definitive door [18]. What the numbers do not license is the unpriced version — "it pops back, keep going, nothing to decide" — because the bone-bill file has already counted what each repeat costs [4][18].

The nerve fence: the numb deltoid, calmly

The fence deserves its numbers. In the prospective Dutch series of 101 primary dislocations and proximal humerus fractures examined clinically and electrophysiologically, 45% had EMG evidence of nerve injury — the axillary nerve leading, then suprascapular, radial and musculocutaneous — significantly more in older patients and in shoulders with a haematoma [20]. Before that number terrifies: most recovered partially or completely within four months, and only eight of 101 had persistent motor loss [20]. The program it prescribes is exact: after a dislocation, a numb patch over the deltoid or weakness lifting the arm sideways gets examined and documented early — not because it usually becomes permanent, but because the rare persistent file wants early physiotherapy, and because deltoid weakness changes what the first weeks of "train everything else" actually are [20]. The adjacent nerve file in this library — the wrist's — runs the same calm arithmetic; the carpal-tunnel guide owns the chronic version of that conversation.

The Brazil anchor: the mirror from Revista Brasileira de Ortopedia

The Brazilian contribution to this file is neither a cohort nor a trial — it is the audit of the audits, and this library's Brazilian readers deserve it straight. The Revista Brasileira de Ortopedia review swept a decade (2007–2016) of the two leading Brazilian orthopedic journals for clinical studies on surgical treatment of anterior glenohumeral instability and found twelve: ten of twelve (83%) level-IV case series, the Rowe score used in 75% and the UCLA scale in 58%, recurrent instability the most-reported complication (75% of studies), and the reviewers' own verdict that the national studies "preferentially used scales considered to be of low reliability, responsiveness, and internal consistency" [21]. Read correctly, that is not an indictment of Brazilian surgery — the international literature the randomized trials above came from is the gold standard precisely because someone audited the case-series era the same way. It is the file's honesty about where the local evidence base stood, and an argument for the Brazilian athlete holding a dislocation report: the operation is the standard one, the outcome measures are getting better, and the questions to ask the surgeon are exactly the ones this audit armed — first time or recurrent, how much bone, which door [4][16][21].

The training-through door: what trains, what waits, what stops

With the fences cleared and the file named, the program writes itself along the family's rules. What trains from the first week: everything that keeps the arm out of the end-range ABER corner — lower-body training in full, unilateral work, trunk work, conditioning, and upper-body work inside the safe arc: neutral-grip pressing, rows from elbow-down positions, curls, internal-rotation and adduction work (the midshipmen's own emphasis), scapular control in all planes; there is no physiological argument for shutting down a squat because a labrum avulsed — the argument is only about where the arm travels [8]. What loads carefully, inside the 24-hour pain budget: pressing arcs graduated by grip and arc depth, the return toward overhead ranges, brace-assisted contact drills in-season — each new rung judged the morning after, apprehension treated as information rather than challenge [18]. What waits: the end-range corner itself — behind-the-neck presses, deep flared dips, the bottom of an untucked bench press, overhead catches — until the definitive door has been chosen and executed [3][16]. What stops: the fences — the still-out shoulder, the pulseless or numb arm, the fracture on the film, the progressive neuro deficit [20]. And what the older recreational lifter with the calm half of the file never stops: half of non-surgical shoulders never redislocate — that door is real, it is priced, and it is taken with eyes open, not by default [5][6][15].

So what do you actually do? The practical file

Six rules, every one sourced from the files above:

  1. Clear the fences before you program the arm. Still out, cold or pulseless, or unreducible is the emergency door — today [20]. The numb deltoid gets examined and documented: 45% carry EMG injuries, most heal inside four months, but the file is watched by a clinician [20]. A fracture on the film is an X-ray-door file — and the tuberosity fracture that protected against recurrence still needs its own clearance before load [6].
  2. Name the file: first time or habitual, age band, sport, bone. The first-time dislocation in a 17-year-old contact athlete and the same event at 38 carry 93%-versus-calmer prognoses (the gradient: 34% of 12–22s versus 9% of 30–40s ended in surgery) [5][7]. Separated shoulder ≠ dislocated shoulder — the clavicle joint has its own audit; the stiff phase after immobilization has its own frozen-shoulder file; the over-40 first dislocation belongs to the cuff.
  3. Retire the sling religion and buy the real program. Immobilization type and duration changed nothing at ten or twenty-five years [5][6], and the external-rotation brace's 0% promise died in a 1,170-patient meta-analysis [9][10]. What the nonoperative door actually is: supervised, goal-gated rehabilitation — internal-rotation and adduction strength first, the corner reintroduced last — which is the door that holds 47% of shoulders stable [8][15].
  4. Price the surgery door by population, not by fear. For the young contact athlete the randomized file is one-directional: 6.3% versus 46.6% recurrence, 4.0% versus 30.8% reoperation, 3.4× return-to-sport for contact players, holding at fourteen years [12][13][14]. For the older recreational lifter, the rehabilitation-first door is legitimate and priced — half never redislocate [5][6][15]. The in-season athlete has the third door: play now at 10.2 days and 37%, operate in the off-season [18].
  5. Bill the bone before each additional episode. One event = 6.8% of glenoid width; every recurrent shoulder crossed the 20% line where Bankart gives way to Latarjet (89% recurrence for contact athletes with bone loss after soft-tissue repair — 4.9% after the bone block) [4][16][17]. Preventing the second dislocation is keeping the surgical menu open — it is the cheapest operation in this file.
  6. Keep the ledger: episodes, ranges, apprehension, dates. Recurrence is the file's currency — the Brazilian review found it the most-reported complication of the surgical era too [21]. A dated log of episodes, near-misses, safe-arc limits and morning-after reactivity is how the calm half of the prognosis gets claimed deliberately [5][6][15].

How RightRep fits into this

The dislocated-shoulder file is, at its core, an episode, arc and appointment tracking question — and it is unanswerable without a record:

  • The episode ledger. Every dislocation, subluxation and near-miss, dated — because the bone bill runs 6.8% per event and the surgical menu closes with each one; an uncounted recurrence is an unbilled installment [4][16].
  • The safe-arc program. Pressing arcs, grip positions and row depths logged per session — the program's one true dial is where the arm travels, and a logged arc is the difference between graduated exposure and accidental rehearsal [3][8].
  • The 24-hour budget. Morning-after reactivity noted beside every new rung — the family's traffic light, applied to the corner that injured the joint [18].
  • The appointment timeline. The nerve exam, the imaging, the surgical consult, the brace, the off-season plan — the 10.2-day in-season door and the fourteen-year surgical edge both live or die by whether the calendar is actually kept [13][18].

The bottom line

  • The census: 23.9 per 100,000 person-years through US emergency departments, twice the prior estimate — 71.8% male, peak in the twenties, 48.3% during sport; among 4,141 cadets, 2.8% per year, and 84.6% of events were subluxations, not dislocations [1][2].
  • The lesion door: 97% of young first-time dislocators carry a Perthes-Bankart avulsion; 57 of 63 Hill-Sachs dents; zero cuff tears; 90% of the nonoperatively treated recurred [3].
  • The bone bill: 6.8% of glenoid width per instability event; first events never crossed 20%; every recurrent shoulder did [4].
  • The prognosis brackets: 93% recurrence at 14–18 versus 40% at ≤13 (OR 24), closed physis OR 14; but 52% no recurrence at ten years, 43% never plus 14.4% stabilized-by-time at twenty-five, 47% never redislocate under non-surgical care [5][6][7][15].
  • The immobilization arc: type and duration changed nothing at ten and twenty-five years; the ER brace's 30%-vs-0% opening closed at 17 studies / 1,170 patients — no difference in recurrence, return to sport or apprehension [5][6][9][10].
  • The randomized file: repair 15.9% vs 47% redislocation; the double-blind trial −76% dislocation risk, contact athletes back in sport 3.4×; at 14.2 years, 12% vs 47%; the five-RCT meta: 6.3% vs 46.6%, reoperation 4.0% vs 30.8% [11][12][13][14].
  • The bone-loss door: 4% recurrence without defects (6.5% in contact athletes) vs 89% in contact athletes with inverted-pear glenoids or engaging Hill-Sachs — and 4.9% for the Latarjet rescue at ≥25% bone loss [16][17].
  • The in-season and return files: 26 of 30 finished the season at 10.2 days, 37% paid a repeat episode; adolescents return at 66–100% after Bankart and 72–94% after Latarjet, with Latarjet's recurrence lowest at 0–8% [18][19].
  • The fences and the anchor: 45% EMG nerve injuries, most healed inside four months, eight of 101 persistent; Brazil's decade of instability surgery was 83% level-IV case series scored on low-reliability scales — the audit every literature needed before its trials arrived [20][21].
