Clinical Outcomes of Patients With Anterior Shoulder Instability and Glenolabral Articular Disruption Lesions: A Retrospective Comparative Study

Background: Anterior shoulder instability is a common clinical condition that often requires surgical stabilization. Glenoid labral tears are often associated with instability, with glenolabral articular disruption (GLAD) lesions occasionally being identified arthroscopically during repair, particularly in collision athletes. Purpose: To evaluate the clinical outcomes and recurrence rates in patients who had GLAD lesions and underwent arthroscopic Bankart repair (ABR) and compare them with a control group without GLAD lesions. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective review of patients who underwent ABR with GLAD lesions, by a single surgeon between July 2012 and March 2017, was performed. Additionally, these were pair matched in a 2:1 ratio for age, sex, sport, and level of play with a control group who underwent ABR without GLAD lesions. Return to sport, the level of return, and the timing of return were assessed. The visual analog scale (VAS) for pain score, Rowe score, Shoulder Instability–Return to Sport after Injury (SIRSI) score, and Subjective Shoulder Value (SSV) were evaluated. Results: The study included a total of 66 patients (22 and 44 patients for the GLAD and control groups, respectively), with a mean age of 25.8 years and a mean follow-up of 66 months. Overall, there was no significant difference in any of the clinical outcome scores (VAS, Rowe, SIRSI, and SSV) utilized for the GLAD and control groups (P > .05 for all). Similarly, there was no significant difference in the total rate of return to play (90.9% vs 88.6%; P > .99) or return at the same/higher level (68.2% vs 72.7%; P = .78). There was no significant difference in timing of return to play (6.3 ± 6.6 months vs 6.4 ± 2.5 months; P = .98). There were 3 cases (13.6%) requiring further surgery (1 revision stabilization, 1 arthroscopic release, and 1 rotator cuff repair) in the GLAD group and 2 cases (4.5%) requiring further surgery (both revision stabilization) in the control group; the difference was not statistically significant (P = .32). Conclusion: After arthroscopic repair, patients with GLAD lesions had similar midterm outcomes when compared with a control group without GLAD lesions.

Recurrent Instability and Surgery Are Common After Nonoperative Treatment of Posterior Glenohumeral Instability in NCAA Division I FBS Football Players.

In-season return to play after anterior glenohumeral instability is associated with high rates of recurrent instability and the need for surgical stabilization. We are not aware of previous studies that have investigated in-season return to play after posterior glenohumeral instability; furthermore, as posterior shoulder instability in collision athletes occurs frequently, understanding the expected outcome of in-season athletes may improve the ability of physicians to provide athletes with a better understanding of the expected outcome of their injury and their ability to return to sport. (1) What proportion of athletes returned to play during the season after posterior instability in collegiate football players? (2) How much time did athletes lose to injury, what proportion of athletes opted to undergo surgery, and what proportion of athletes experienced recurrent instability after a posterior instability episode during a collegiate football season? A multicenter, prospective, observational study of National Collegiate Athletic Association (NCAA) Division 1 Football Bowl Subdivision athletes was performed at three US Military Service Academies. Ten athletes who sustained a posterior instability event during the regular football season and who pursued a course of nonoperative treatment were identified and prospectively observed through the subsequent season. All athletes in the observed cohort attempted an initial course of nonoperative treatment during the season. All athletes sustained subluxation events initially identified through history and physical examination at the time of injury. None of the athletes sustained a dislocation event requiring a manual reduction. Intraarticular pathology consisting of posterior labral pathology was further subsequently identified in all subjects via MRI arthrogram. Return to play was the primary outcome of interest. Time lost to injury, surgical intervention, and subsequent instability were secondary outcomes. Of the 10 athletes who opted for a trial of initial nonoperative management, seven athletes were able to return to play during the same season. Although these seven athletes returned within 1 week of their injury (median of 1 day), 5 of 7 athletes sustained recurrent subluxation events with a median (range) of four subluxation events per athlete (0 to 8) during the remainder of the season. Seven athletes were treated surgically after the completion of their season, four of whom returned to football. This study suggests that although collegiate football players are able to return to in-season sport after a posterior glenohumeral instability event, they will likely sustain multiple recurrent instability events and undergo surgery after the season is completed. The results of this study can help guide in-season management of posterior shoulder instability by allowing more appropriate postinjury counseling and decision making through the identification of those athletes who may require additional attention from medical staff during the season and possible modifications to training regimens to minimize long-term disability. Further prospective studies involving a larger cohort over several seasons should be performed through collaborative studies across the NCAA that better assess function and injury risk factors before beginning collegiate athletics. This would better characterize the natural history and associated functional limitations that athletes may encounter during their collegiate careers. Level IV, prognostic study.

Posterior Labral Injury and Glenohumeral Instability in Overhead Athletes: Current Concepts for Diagnosis and Management.

Posterior glenohumeral instability in overhead athletes presents a unique set of challenges for both diagnosis and treatment. Although a great deal of attention has been focused on the management of injuries to the biceps-labrum complex and rotator cuff in throwers, comparatively less has been written about posterior glenohumeral instability within this unique cohort. Historically, posterior instability has been observed secondary to either acute trauma or repetitive microtrauma, usually among collision athletes, weight lifters, and rowers. However, posterior glenohumeral instability resulting from pathology of the posterior capsulolabral tissues in throwers is a different entity, and the clinical assessment begins with an accurate differentiation between adaptive capsular laxity and labral injury with pathologic instability. Some posterior capsule labrum tears confirmed on arthroscopy will require nothing more than débridement. However, for more extensive lesions, surgical treatment must balance the necessity to repair torn capsulolabral tissues with the tendency to over constrain the shoulder. The literature provides mixed results regarding the likelihood of overhead athletes with posterior glenohumeral instability and labral injury treated surgically returning to their preinjury level of sport performance.

The Prevalence and Management of Stingers in College and Professional Collision Athletes.

Particularly common in collision sports such as American football or rugby, stingers are a traumatic transient neuropraxia of a cervical nerve root(s) or brachial plexus that may last anywhere from minutes to hours. This review summarizes the knowledge on the diagnosis and management of stingers in college and professional collision athletes by providing an overview of their epidemiology and pathophysiology, followed by a discussion on current treatment guidelines and return-to-play recommendations. Despite modifications to tackling technique, increasing awareness, and various equipment options, American football continues to have a high rate of cervical spine injuries, the majority of which occur in preseason and regular season competition settings. The incidence of stingers has slowly increased among collision athletes, and nearly half of all players report sustaining at least one stinger in their career. Recent studies have shown certain anatomical changes in the cervical spine are related to acute and reoccurring stingers. Most players who experience stingers do not miss practices or games. Despite their prevalence, literature highlighting the impact of stingers on college and professional collision athletes is limited. Advances in imaging modalities and novel radiographic parameters have provided tools for screening athletes and can guide return-to-play decisions. Future research regarding appropriate screening practices for athletes with reoccurring stingers, use of protective equipment, and rehabilitation strategies are needed to identify predisposing factors, mitigate the risk of injury, and restore full functional strength and ability.

Double-loaded suture anchors in the treatment of anteroinferior glenohumeral instability

HypothesisThe purpose of this study was to determine the clinical outcomes of arthroscopic labral repair for anteroinferior glenohumeral instability with the use of double-loaded suture anchors.MethodsThis study evaluated a series of consecutive patients treated after the senior author changed from single- to double-loaded suture anchors for the treatment of anteroinferior glenohumeral instability with a minimum follow-up period of 2 years. We collected the following outcomes at final follow-up: visual analog scale pain score, Simple Shoulder Test score, American Shoulder and Elbow Surgeons score, and instability recurrence data.ResultsA total of 41 consecutive patients underwent arthroscopic labral repair with double-loaded anchors, of whom 30 (71%) were able to be contacted at a minimum of 2 years postoperatively. These patients included 4 contact or collision athletes (13%). The patients had an average of 12 ± 13 prior dislocations over an average period of 56 ± 57 months preoperatively. Mean glenoid bone loss measured 16% ± 10%, and 67% (18 of 27 patients) had glenoid bone loss ≥ 13.5%. Intraoperatively, 3.2 ± 0.4 anchors were used. No posterior repairs or remplissage procedures were performed. At an average of 6.7 ± 2.7 years' follow-up, the visual analog scale pain score was 0.8 ± 1.4; Simple Shoulder Test score, 11 ± 2; and American Shoulder and Elbow Surgeons score, 90 ± 14. Patients with bone loss < 13.5% had a 0% redislocation rate and 11% subluxation rate, whereas those with bone loss ≥ 13.5% had a 6% reoperation rate, 22% redislocation rate, and 22% subluxation rate.ConclusionArthroscopic labral repair with double-loaded anchors provides satisfactory clinical results at early to mid-term outcome assessment when glenoid bone loss is <13.5%.

A single-institution analysis of factors affecting costs in the arthroscopic treatment of glenohumeral instability

BackgroundAlthough surgical shoulder stabilization is a substantial cost nationally within the United States, little information exists to analyze this cost. The purpose of this study was to identify factors associated with variation in direct costs with the arthroscopic treatment of glenohumeral instability.MethodsThis was a retrospective study of all patients who underwent arthroscopic treatment of glenohumeral instability between January 12, 2012 and July 11, 2017. Patient and procedure factors were collected. Direct perioperative costs were collected using a validated internal tool. Patient and procedure characteristics significantly associated with costs were identified using multivariate generalized linear models.ResultsThe study included 302 patients, of whom 12% were undergoing revision and 32% were contact or collision athletes. Anterior instability was present in 73%, whereas 14% had posterior and 10% had multidirectional instability. Of the patients, 67% were recurrent dislocators and 33% were first-time dislocators or subluxators. Remplissage was performed in 13%; biceps tenodesis, 5%; and rotator cuff repair, 3%. An average of 4.0 ± 1.4 anchors were used. Of costs, 39% were operative facility utilization costs and 41% were implant costs. Factors associated with cost increase included an increased number of anchors (P < .0001), posterior vs. anterior instability (P = .001), recurrent instability vs. first-time dislocation (P = .025), remplissage (P = .006), rotator interval closure (P = .021), bicep tenodesis (P = .020), rotator cuff repair (P < .0001), an inpatient stay (P = .003), and repair of humeral avulsion of the glenohumeral ligaments (P = .012).ConclusionMost perioperative costs associated with the arthroscopic treatment of glenohumeral instability are facility utilization and implant costs. Nonmodifiable factors associated with increased cost included posterior direction of instability and recurrent instability. Modifiable factors included additional procedures and inpatient stay.

Epidemiology of Injuries Sustained in Boys' High School Contact and Collision Sports, 2008-2009 Through 2012-2013.

Background:Injury epidemiology for boys’ high school contact and collision sport has been described in several overlapping but fragmented studies. Comprehensive comparisons of injuries sustained in boys’ soccer, wrestling, football, ice hockey, and lacrosse are lacking.Purpose:To describe patterns of injury by severity, body site, and diagnosis among high school boys’ contact and collision sports in the United States.Study Design:Descriptive epidemiology study.Methods:Injury rates and rate ratios (RRs) were calculated for injuries sustained in boys’ high school soccer, wrestling, football, ice hockey, and lacrosse through use of the High School RIO (Reporting Information Online) surveillance data from 2008-2009 through 2012-2013. Injury patterns were described by site, diagnosis, time loss, and severity. Severe injury was defined as an injury that resulted in 21 days or more of time loss from sport participation. Risk of sustaining a concussion was compared between sports.Results:The risk of sustaining an injury was higher in competition compared with practice overall (RR, 4.01; 95% CI, 3.90-4.12); the same pattern was true for severe injuries (RR, 4.61; 95% CI, 4.34-4.90). Football players experienced the highest injury rate (3.87 per 1000 athlete-exposures [AEs]) and the highest severe injury rate (0.80 per 1000 AEs). Overall, the most commonly injured body site was the head/face (22.5%), and the most prevalent injury diagnosis was ligament sprain not requiring surgery (23.5%). The most frequently injured body site from severe injury was the knee (24.6%), and fracture or avulsion was the most prevalent severe injury diagnosis (37.0%). Football players had a significantly higher risk of sustaining a concussion compared with other contact or collision sport athletes (P < .05).Conclusion:Injuries rates were higher in competition than those in practice for boys’ high school contact and collision athletes. Football players sustained the highest injury rate, the highest severe injury rate, and the highest concussion rate among the sports included in this analysis. Understanding these patterns of injury can generate policy and rule changes to make sports safer and maintain high levels of participation.

Epidemiology of Shoulder Instability Injuries in Collision Collegiate Sports From 2009 to 2014

To describe the types, mechanisms, and severity of shoulder instability injuries in collegiate collision athletes during the 2009-2010 through 2013-2014 academic years using the National Collegiate Athletic Association Injury Surveillance Program; to compare the injury incidence between men's collision sports and their women's non-collision counterparts, when possible; and to compare injury outcomes between Divisions I, II, and III. Data regarding men's football, wrestling, ice hockey, and lacrosse, as well as women's ice hockey and lacrosse, were obtained. Injuries requiring attention from a health care provider were reported. Incidence rates per 100,000 athlete-exposures (AEs) were calculated with 95% confidence intervals (CIs). Analysis of variance was used to compare time loss (TL), and χ2 analysis was used to compare surgery rates between divisions. A total of 445 shoulder instability injuries occurred in 1,421,561 AEs from 2009-2010 to 2013-2014 (incidence rate, 31.30 injuries/100,000 AEs; 95% CI, 28.4-34.21 injuries/100,000 AEs). Subluxation accounted for 59.1% of injuries, with anterior subluxation (35.3%) being the most common injury. Dislocation resulted in the most TL per injury (17.58days). Mean TL for all injuries was 8.17days (standard deviation, 7.21days). When non-time-loss injuries were excluded from analysis, players experienced a mean TL of 18.34days (standard deviation, 8.44days). Divisions I (4.77days), II (20.52days), and III (11.23days) differed significantly in mean TL (P= .01). Of the injuries, 29.3% required surgery. The surgery rates for Divisions I (32.9%), II (38.1%), and III (19.4%) also differed significantly (P= .04). Men's ice hockey and lacrosse players sustained a 2.17-fold (95% CI, 1.04-4.50) higher incidence of shoulder instability than their female counterparts. Anterior subluxation and dislocation accounted for 52.1% of all shoulder instability injuries. Injured athletes missed 8days on average, and nearly 30% of injuries required surgery. Surgery rates and TL were significantly different between Divisions I, II, and III. Female athletes playing non-collision ice hockey and lacrosse experienced significantly lower shoulder instability rates than their male counterparts. Level III, retrospective cohort study.

Scapula Fractures in Elite Soccer and Rugby Players

Background:Scapula fractures are uncommon in sports and are poorly understood in this patient group.Purpose:To report on scapula fractures in contact and collision athletes and assess the injury patterns of different mechanisms of injury.Study Design:Case series; Level of evidence, 4.Methods:A retrospective case series was performed of all sports-related scapula fractures treated at a single institution between 2007 and 2015. The mechanisms of injury were divided into direct lateral impact, fall onto an outstretched arm, or abduction/external rotation.Results:A total of 11 patients were identified: 9 professional rugby players, 1 professional soccer player, and 1 amateur soccer player. The mean age was 28 years (range, 18-35 years). The mean return to play was 127 days in those treated nonoperatively and 163 days in those treated operatively. A direct impact mechanism occurred in 7 patients, all of whom sustained glenoid neck and body fractures and were treated nonoperatively. Two rugby players had a concomitant suprascapular nerve injury. An outstretched arm mechanism occurred in 2 cases, leading to posterior and inferior glenoid fractures. Both patients were treated operatively. An abduction/external rotation mechanism occurred in 2 cases, resulting in an anteroinferior and an anterior glenoid rim fracture. One case was treated operatively and the other was treated nonoperatively. Of those with glenoid fractures, 75% were not visible on plain radiographs and required further imaging.Conclusion:Scapula fractures acquired in sports are a serious injury with a prolonged recovery period. The mechanism of injury can help predict the injury pattern and highlight the need for further imaging. There is a high association with suprascapular nerve injuries.

Management and Outcomes of In-Season Anterior Shoulder Instability in Athletes.

» Anterior shoulder dislocation is a common problem in athletes and has serious implications due to the rate of injury recurrence and the resulting extended time out of play.» There are a variety of management options that address shoulder instability in an in-season athlete, and the decision-making approach should be individualized to the athlete.» Although nonoperative management and return to play in the same season may be a suitable option for a subset of athletes who wish to return to play as soon as possible (during a recruiting season, for an upcoming Combine, or if they are in the last season of their career), given the high risk of recurrence, we recommend that immediate surgical intervention should be considered to decrease the risk of further damage to the glenohumeral joint.» Arthroscopic stabilization currently is the most commonly performed intervention for athletes with anterior shoulder instability in the United States, but open repair remains an excellent option for high-risk patients.» In collision athletes with subcritical glenoid bone loss between 13.5% and 25%, early open anterior capsulolabral reconstruction or a Latarjet procedure is recommended. If glenoid bone loss exceeds 25%, the Latarjet or another glenoid osseous augmentation procedure should be performed to reduce the risk of recurrent anterior instability.

The Effect of Repetitive Head Impact in Sensory Reweighting in Collision College Athletes

ObjectiveTo compare sensory reweighting for upright stance between collegiate collision and non-contact sport athletes.BackgroundThe potentially adverse effects of repetitive head impact (RHI) exposure through routine collision sport participation have become a major public health concerns.Design/MethodsThirty male collegiate athletes were grouped by sport type, including collision (n = 15, 21.2 ± 2 years, 85.9 ± 13.8 kg, 179.7 ± 8.2 cm) and non-contact (n = 15, 20.8 ± 2.1 years, 72.9 ± 4.8 kg, 178.3 ± 4.3 cm) sport athletes. Participants underwent a standing balance assessment; they experienced simultaneous perturbations to visual, vestibular, and somatosensory systems. The visual stimulus consisted of 500 pyramids displayed on a virtual reality cave and translated in the anterior-posterior direction at 0.2 Hz in a sinusoidal waveform. The vestibular stimulus consisted of binaural-monopolar galvanic vestibular stimulation (GVS) at 0.36 Hz in a sinusoidal waveform. The somatosensory stimulus consisted of bilateral Achilles’ tendon vibration at 0.28 Hz in a square waveform with equal on/off times. Different frequencies were chosen for each modality so that we could calculate the gain to each stimulus independently. There were four conditions: two conditions of each high amplitude (0.2 m) and low amplitude (0.8 m) visual scene translation and two conditions of each vibration on and vibration off. The leg segment gain to each modality was compared between groups and across conditions using a repeated-measures ANOVA.ResultsThere were no changes in leg segment gain to vision (i.e. group effect; F = 2.624, p = 0.094, η2 = 0.086), gain to GVS (F = 1.341, p = 0.266, η2 = 0.46), or gain to vibration (F = 3.124, p = 0.088, η2 = 0.100). In addition, there were no changes in sensory reweighting for any modality (i.e. condition X group effect; vision, F = 0.074, p = 0.788, η2 = 0.003; GVS, F = 0.547, p = 0.46, η2 = 0.019; vibration, F = 0.734, p = 0.399, η2 = 0.026).ConclusionsOur findings suggest that there are no differences in sensory reweighting between collegiate collision and non-contact sport athletes. Despite concerns that RHI exposure through routine collision sport participation may result in balance disturbances, our results do not support this association.

Arthroscopic Soft Tissue Stabilization for Traumatic Anterior Shoulder Instability in Elite Collision Athletes: Is it Sufficient?

Objectives: Surgical options for shoulder instability in collision athletes remain controversial. Although arthroscopic soft tissue stabilization is widely accepted treatment for shoulder instability, many surgeons prefer coracoid transfer for collision athletes with or without glenoid defect due to potential high recurrence rate after arthroscopic soft tissue Bankart repair (ABR). In the meantime, Hill-Sacks remplissage (HSR) has been gaining popularity as an effective arthroscopic augmentation procedure. Since 2002, we performed rotator interval closure (RIC) as an augmentation in addition to ABR or arthroscopic bony Bankart repair (ABBR) for collision athletes and obtained satisfactory outcome. However, teen players demonstrated higher recurrence rate compared to twenties and thirties. Therefore, from 2012, we performed HSR as an additional augmentation for teen players besides ABR/ABBR and RIC. The purpose of this study was to assess the outcomes after arthroscopic stabilization in collision athletes who underwent shoulder stabilization under our treatment strategy. Methods: Between 2012 through 2015, 95 consecutive collision athletes underwent shoulder stabilization. Among those, only 2 patients (2%) underwent arthroscopic bony procedure for poor capsular integrity. Among the remaining 93 patients who underwent soft tissue stabilization, 65 were available for minimum 2 year follow-up (70%). Therefore, subjects consisted of 65 players including 54 rugby and 11 American football players (Table 1). There were 13 national top league, 24 collegeate, 21 junior or senior high school, and 7 recreational players. The mean age at surgery was 20 years (range, 16-36). The mean follow-up was 37 months (range, 24-64). We retrospectively reviewed intraoperative findings and surgical procedures using patient records including surgical reports and videos. We also investigated the mean time for sports return, functional outcome and recurrence rate. Pre- and postoperative Rowe scores were compared using paired t test. Results: Preoperative 3DCT of the glenoid demonstrated bony Bankart (fragment type) in 43 players (66%), attritional type in 16 (25%), and normal glenoid in 6 (9%). Mean glenoid bone loss was 15% (range, 0-25) and all of the glenoid with more than 10% bone loss retained bony fragment (Table 2). All 65 players demonstrated Bankart lesion and 15 had concomitant SLAP lesion (23%) which required repair. In addition, 5 players demonstrated capsule tear (8%), which were also repaired. Twenty four players (36%) underwent ABR or ABBR with RIC and forty one players (64%) underwent ABR or ABBR combined with HSR (Table 1).The mean time for sports return was 7 months (range, 4-13) after surgery. The mean Rowe score significantly improved after surgery from 65 (range, 55-75) to 92 (range, 65-100) (P &lt; .001). Recurrence appeared in 2 cases (3%), both of which were junior or senior high school players who underwent ABR with HSR. Conclusion: Soft tissue stabilization combined with selective augmentation procedures for shoulder instability in collision athletes demonstrated satisfactory outcomes with low recurrence rate. Since the incidence of having bony Bankart lesion in collision athletes was very high, arthroscopic bony Bankart repair worked in many patients even with significant glenoid bone loss. Further, HSR seemed to be effective additional augmentation especially in young collision athletes. [Table: see text][Table: see text]

Diffusion Tensor Imaging in Athletes Sustaining Repetitive Head Impacts: A Systematic Review of Prospective Studies.

Competitive sport participation, in contact and collision sports, exposes athletes to repetitive head impacts. Although these impacts do not always result in overt symptomology or a diagnosed "concussion," evidence indicates that cumulative repetitive impacts affect brain pathophysiology. The purpose of this study was to perform a systematic review of prospective, longitudinal trials evaluating repetitive head impact exposure on white matter (WM) microstructure in collision and contact sport athletes to inform clinical care and treatment strategies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed to determine studies that met predetermined inclusion and exclusion criteria. Initially, 2498 abstracts were identified, and 20 studies were critically evaluated herein. The majority of studies demonstrated significant longitudinal changes in anisotropy and/or diffusivity metrics that were associated with the quantity and/or the magnitude of head impact exposure, highlighting the utility of diffusion tensor imaging (DTI) for measuring changes in WM microstructure. Our review also comments on study methodology and describes how age, sex, sport, and time between sport cessation and DTI measures contribute to divergent findings within the literature. Suggestions for future research are also provided to overcome previous study limitations and maximize our understanding of the role of repetitive head impact exposure on WM integrity and long-term neurological sequela.

Return to Play After the Latarjet Procedure for Anterior Shoulder Instability: A Systematic Review

Background: Traumatic anterior shoulder instability is a common clinical problem among athletic populations. The Latarjet procedure is a widely used treatment option to address shoulder instability in high-demand athletes at high risk of recurrence. However, rates and timing of full return to sports have not been systematically analyzed. Purpose: To systematically review the evidence in the literature to ascertain the rate and timing of return to play and the availability of specific criteria for safe return to play after the Latarjet procedure. Study Design: Systematic review. Methods: A systematic literature search was conducted based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, using the EMBASE, MEDLINE, and Cochrane Library databases. Eligible for inclusion were clinical studies reporting on return to play after the Latarjet procedure. Statistical analysis was performed by use of SPSS. Results: Our review found 36 studies including 2134 cases meeting our inclusion criteria. The majority of patients were male (86.9%), with a mean age of 25.4 years (range, 15-59 years) and a mean follow-up of 83.5 months. The overall rate of return to play was 88.8%, with 72.6% returning to the same level of play. Among collision athletes, the overall rate of return to play was 88.2%, with 69.5% returning to the same level of play. In overhead athletes, the overall rate of return to play was 90.3%, with 80.6% returning to the same level of play. The mean time to return to play was 5.8 months (range, 3.2-8 months). Specific return to play criteria were reported in the majority of the studies (69.4%); time to return to sport was the most commonly reported item (66.7%). Conclusion: The overall rate of return to play was reportedly high after the Latarjet procedure. However, almost a fifth of athletes returning to sports were not able to return at the same level. Further development of validated criteria for safe return to sports could potentially improve clinical outcomes and reduce recurrence rates.

Arthroscopic Soft Tissue Stabilization for Traumatic Anterior Shoulder Instability in Elite Collision Athletes

Objectives: Surgical options for shoulder instability in collision athletes remain controversial. Although arthroscopic soft tissue stabilization is widely accepted treatment for traumatic anterior shoulder instability, many surgeons prefer coracoid transfer such as Latarjet procedure for collision athletes with or without glenoid defect due to potential high recurrence rate after arthroscopic soft tissue Bankart repair (ABR). In the meantime, Hill-Sachs remplissage (HSR) has been gaining popularity as an effective arthroscopic augmentation procedure. Since 2002, we performed rotator interval closure (RIC) as an augmentation in addition to ABR or arthroscopic bony Bankart repair (ABBR) for collision athletes and obtained satisfactory outcome.

Among the remaining 93 patients who underwent soft tissue stabilization, 65 were available for minimum 2-year follow-up (70%). Therefore, subjects consisted of 65 players including 54 rugby and 11 American football players (Table 1). There were 13 national top league, 24 collegiate, 21 junior or senior high school, and 7 recreational players. The mean age at surgery was 20 years (range, 16-36). The mean follow-up was 37 months (range, 24-64). We retrospectively reviewed intraoperative findings and surgical procedures using patient records including surgical reports and videos. We also investigated functional outcome and recurrence rate. Pre- and postoperative Rowe scores were compared using paired t test. Results: Preoperative 3DCT of the glenoid demonstrated bony Bankart (fragment type) in 43 players (66%), attritional type in 16 (25%), and normal glenoid in 6 (9%). Mean glenoid bone loss was 15% (range, 0-25) and all of the glenoid with more than 10% bone loss retained bony fragment. All 65 players demonstrated Bankart lesion and 15 had concomitant SLAP lesion (23%) which required to be repaired. In addition, 5 players demonstrated capsule tear (8%), which were also repaired. Twenty-four players (36%) underwent ABR or ABBR with RIC and forty one players (64%) underwent ABR or ABBR combined with HSR (Table 1). The mean Rowe score significantly improved after surgery from 65 (range, 55-75) to 92 (range, 65-100) (P &lt; .001). Recurrence appeared in 2 cases (3%), both of which were junior or senior high school players who underwent ABR with HSR. Ten national top league players who underwent ABR with RIC had no recurrence. Conclusion: Soft tissue stabilization combined with selective augmentation procedures for traumatic shoulder instability in collision athletes demonstrated satisfactory outcomes with extremely low recurrence rate. Since the incidence of having bony Bankart lesion in collision athletes was very high, arthroscopic bony Bankart repair worked in many patients even with significant glenoid bone loss. Further, Hill-Sachs remplissage seemed to be effective additional augmentation especially in young collision athletes. [Table: see text]

Recurrence After Arthroscopic Labral Repair for Traumatic Anterior Instability in Adolescent Rugby and Contact Athletes

Background: Traumatic glenohumeral dislocation of the shoulder is one of the most common shoulder injuries, especially among adolescent athletes. The treatment of instability for young athletes continues to be controversial owing to high recurrence rates. Purpose: To investigate the recurrence rate of shoulder instability after arthroscopic capsulolabral repair for adolescent contact and collision athletes. Study Design: Case series; Level of evidence, 4. Methods: Sixty-seven patients aged <18 years underwent an arthroscopic labral repair over a 5-year period. The mean ± SD age of the cohort was 16.3 ± 0.9 years (range, 14-17 years) and consisted of 1 female and 66 males. All patients were contact athletes, with 62 of 67 playing rugby. Demographic, clinical, and intraoperative data for all patients with shoulder instability were recorded in our database. Recurrence rates were recorded and relative risks calculated. Results: At a follow-up of 33 ± 20 months, 34 of 67 patients had recurrent instability for an overall recurrence rate of 51% among adolescent contact athletes after arthroscopic labral repair surgery. The mean time to recurrence was 68.1 ± 45.3 weeks. All recurrences occurred as a result of a further sporting injury. Relative risk analysis demonstrated that athletes aged <16 years had 2.2 (95% CI, 1.2-2.1) times the risk of developing a further instability episode as compared with athletes aged ≥16 years at the time of index surgery (P = .0002). The recurrence rate among adolescent athletes after bony Bankart repairs was 57.9% versus 47.9% for soft tissue labral repairs (P = .4698). The incidence of Hill-Sachs lesions (P = .0002) and bony Bankart lesions (P = .009) among adolescent athletes was significantly higher than among adult controls (P = .002). The presence of bone loss did not lead to a significant increase in recurrence rate over and above the effect of age. Conclusion: Adolescent contact athletes undergoing arthroscopic labral repair have an overall recurrence rate of 51%. Rugby players who undergo primary arthroscopic shoulder stabilization aged <16 years have 2.2 times the risk of developing a further instability episode when compared with athletes aged ≥16 years at the time of index surgery, with a recurrence rate of 93%.

Shoulder Instability in the Overhead Athlete.

Shoulder instability encompasses a spectrum of disease ranging from subluxation to dislocation, and is typically associated with collision athletes such as wrestlers and football players. Instability, however, also can be the result of repetitive microtrauma, as seen in overhead athletes (baseball, tennis, volleyball, swimming). The presentation of instability can be subtle, and difficult to diagnose in the absence of an acute traumatic event without the proper suspicion, physical examination, and diagnostic evaluation. Overhead athletes present the unique challenge of requiring the glenohumeral joint to exceed its physiologic limits during competition; therefore, injury in this population can be devastating. Additionally, athletes who experience instability, regardless of treatment, require rehabilitation (including periscapular strengthening) to maximize strength of the surrounding musculature. Specifically they will require coordinated throwing programs, and gradual return to play protocols dependent on their sport. This article reviews the specific physiology, diagnosis, and treatment of shoulder instability in this population.
