Recurrent Anterior Shoulder Dislocation with Coracoid Fracture in an Old Age Male: A Rare Case Report.

Introduction: Anterior shoulder dislocation is a common pathology in young males with less prevalence in other age groups. Anterior shoulder dislocation being the most common variety of dislocation among the shoulder dislocation can be managed both conservatively and surgically. Recurrent anterior dislocation in middle-aged males with a coracoid fracture is a rare entity and should be managed with proper pre-operative planning including computed tomography (CT) scan, magnetic resonance imaging (MRI), and surgery. Case Report: A 65-year-old male is a known case of recurrent anterior dislocation presented with anterior shoulder dislocation 1½ years back. Closed reduction was done. Radiological evaluations such as CT scan and MRI were done which were suggestive of bony Bankart and coracoid fracture which was managed with open Latarjet procedure. Conclusion: Recurrent anterior shoulder dislocation with a concomitant coracoid fracture is a rare entity in old age, which can be managed with a Latarjet procedure and has a good post-operative outcome.

Treatment of Anterior Shoulder Instability: A Comprehensive Review.

Anterior shoulder instability is a complex spectrum of pathology characterized by excessive translation of the humeral head across the glenoid, leading to apprehension, subluxation, and dislocation. Diagnosis and classification require a thorough clinical history, physical examination, and imaging to appropriately determine the severity of instability. Depending on the individual patient anatomy and severity of instability, there exist many management options that are well-positioned to successfully treat this pathology and allow patients to return to prior functional levels. Treatment options available are conservative management, arthroscopic or open Bankart repair, remplissage, open or arthroscopic Latarjet, and glenoid bone grafting. Each of these options provides unique advantages for the surgeon in treating a subset of patients along the spectrum of disease. Selection of treatment modality depends upon the number of instability events, appropriate quantification, classification bone loss, presence of associated soft tissue injuries, and patient-specific goals regarding return of function. The purpose of this review was to present an evidence-based approach to the investigation, treatment selection, and follow-up of anterior shoulder instability. Individualized patient care is required to optimally address intra-articular pathology, restore stability and function, and preserve joint health for all.

Promising clinical effect of arthroscopic autologous iliac bone grafting with suture anchor binding fixation for recurrent anterior shoulder instability.

Background: To evaluate the clinical efficacy of arthroscopic autologous iliac bone grafting with suture anchor binding fixation combined with a Bankart repair for recurrent anterior shoulder dislocation with a significant anterior glenoid defect. Methods: Patients with recurrent anterior shoulder dislocation with an anterior glenoid defect area greater than 20% admitted to our department from March 2019 to March 2022 were prospectively enrolled. Arthroscopic autologous iliac bone grafting with suture anchor binding fixation combined with a Bankart repair was performed. Computed tomography (CT) images were captured preoperatively, immediately after surgery, and at 3, 6, and 12 months postoperatively to evaluate the glenoid defect area, graft area, and graft healing. Shoulder function was assessed using the Instability Severity Index, Oxford Shoulder Instability, and Rowe scores recorded preoperatively and at the final follow-up. The shoulder range of motion, shoulder stability test, surgery-related complications, subluxation/dislocation, and revision surgery were also evaluated. Results: A total of 32 patients were included in the study, with an average follow-up time of 18.3 ± 6.3 months, when the graft healing rate was shown to be 100%. The area ratio of the graft to the glenoid was 37.6% ± 10.5% (range, 23.5%-44.1%) determined by an enface-view three-dimensional CT performed immediately after surgery, and 29.2 ± 8.2% (range, 19.6%-38.7%) at 12 months postoperatively. At the final follow-up, the glenoid defect had improved from 28.7 ± 6.4% (range, 20.5%-40.6%) before surgery to -10.2 ± 4.7% (range, -13.8% to 6.1%). The preoperative Rowe and Oxford scores were 56.4 ± 8.5 and 34.7 ± 7.1 respectively, which improved to 94.3 ± 6.7 and 15.3 ± 3.2 at the final follow-up (p < .001). All patients had no limited shoulder joint activity, no re-dislocation or revision surgery, and no neurovascular injury. Conclusions: For recurrent anterior shoulder dislocation with an anterior glenoid defect area greater than 20%, arthroscopic autologous iliac bone grafting with suture anchor fixation combined with a Bankart repair produced a promising clinical effect. A significant shoulder function score was achieved, as was a 100% bone healing rate and ideal glenoid reconstruction without major complications. Thus, this technique may be considered an alternative to the classic Latarjet approach to treat recurrent anterior shoulder dislocation with an anterior glenoid defect area greater than 20%. Level of Evidence: IV.

Pyrocarbon Hemi-Shoulder Arthroplasty Provides Satisfactory Outcomes Following Prior Open Latarjet.

Purpose: To assess the clinical and radiographic outcomes, at a minimum follow-up of 4 years, following HSA using pyrocarbon in patients that had prior open Latarjet. Methods: The authors retrieved the records of 61 consecutive patients that underwent HSA with a pyrocarbon humeral head at 2 centers between December 2013 and October 2019. Eight patients (9 shoulders) had undergone previous Latarjet procedures without other surgical antecedents. Patients underwent radiological assessment, and clinical assessment including Constant score, Subjective Shoulder Value (SSV), and pain on VAS. Finally, range of motion was assessed, including active forward elevation and external rotation. Results: The initial cohort of 9 shoulders, comprised 1 woman and 7 men (1 bilateral), aged 52.5 ± 5.2 at their index HSA, which was performed 27.7 ± 9.3 years following their prior Latarjet procedure. One shoulder required conversion to reverse shoulder arthroplasty, 3 years after HSA. The remaining 8 shoulders were assessed at 6.1 ± 1.6 years (range, 4-8) after the index HSA. Glenoid erosion only progressed in 1 shoulder from mild to moderate. The Constant score was 79.6 ± 12.7, pain on VAS was 1.0 ± 2.1, and SSV was 80.0 ± 25.6. The active forward elevation improved from 96°±41° to 151°±29°, and external rotation from 11°±17° to 32°±8°. Conclusion: Patients that underwent HSA using pyrocarbon heads following prior Latarjet had satisfactory clinical scores, and glenoid erosion only progressed in 1 patient. Furthermore, only 1 patient required conversion to RSA. The clinical relevance is that HSA using pyrocarbon heads is a safe treatment and grants satisfactory clinical outcomes in patients with prior Latarjet. Level of Evidence: Level III, retrospective comparative study.

Outcomes of Arthroscopic Cortical-Button Latarjet Procedure with Minimum Five Year Follow-Up.

INTRODUCTION: The surgical treatment of anterior shoulder instability with arthroscopic cortical-button Latarjet procedure has been the subject of very few medium and long-term studies. The aim of this study was to analyze the clinical and radiological results of arthroscopic cortical-button Latarjet procedure with minimum 5 years follow-up. METHOD: This is a monocentric retrospective study including 40 patients who have undergone shoulder stabilization with primary arthroscopic cortical-button Latarjet procedure and been reviewed with minimum 5 years follow-up. The average age at the time of surgery was 26.6 years (16 - 59; ± 10) and 92.5% were sporty individuals. The average ISI score was 6 points (2- 9; ± 1,6). The clinical evaluation involved active range of motion measurement, apprehension test, Rowe and Walch-Duplay scores, SSV and Net Promoter Score. Radiologically, evolution of the bone graft and degenerative arthritis of the shoulder joint were analyzed at the last follow-up. RESULTS: At an average follow-up of 71 months (60 - 97; ± 12), 3 patients (7.5%) experienced recurrence as a dislocation or subluxation, which was responsible for revision in 1 case. Moreover, apprehension persisted in 6 (16%) patients. There were no significant restrictions in recovery of active ranges of motion, including external rotation. Return to sports was effective in 94.6% of cases. The average Rowe and Walch-Duplay scores were 87 points (15 - 100; ± 20) and 88 points (15 - 100; ± 19) respectively. SSV was 91% (10 - 100; ± 16) and NET Promoter Score was 9.3 points (5 - 10; ± 1,3). Radiologically, degenerative arthritis occurred in 18.7% of patients, mainly asymptomatic stage 1 (9.4%). Bone healing was acquired in 72% of cases and partial lysis of the bone block in 41%. CONCLUSION: At an average follow-up of 6 years, arthroscopic cortical-button Latarjet procedure effective, enabling return to sport in 95% of cases. Onset of asymptomatic arthritis seems similar to conventional techniques but justifies a more long-term follow-up.

Biomechanical comparison shows increased stability of an arthroscopic subscapular sling procedure compared to an open Latarjet reconstruction for anterior shoulder instability in specimens with major glenoid bone defect.

Purpose: Recurrent anterior glenohumeral instability (RASI) is commonly treated with arthroscopic techniques, though their effectiveness in providing stability may diminish in cases of critical glenoid bone loss. This study aimed to compare the stability outcomes and range of motion (ROM) associated with an arthroscopic subscapular sling procedure (SSP), first introduced in 2015. Methods: Sixteen fresh-frozen human cadaveric shoulder specimens were biomechanically evaluated in four conditions: native, injured, post-SSP and post-LP. Glenohumeral translations were measured under anterior, anteroinferior and inferior loading, while external rotation ROM was assessed in neutral and abducted positions. Testing was conducted using a robotic system for precise force and torque application. Specimens were prepared with a 20% glenoid bone defect and subjected to stability testing sequentially. Results: The SSP significantly reduced glenohumeral translations compared to LP, particularly under anterior loading in neutral (p < 0.001), external rotation (p = 0.007) and abduction (p < 0.001) positions. Although the SSP demonstrated superior stability in these key positions, it did not consistently outperform the LP across all scenarios, as stability was similar between the two in the abducted and rotated position under anterior loading (p = 0.379). Under anteroinferior loading, the SSP showed comparatively better stability at neutral (p = 0.003) and abduction (p < 0.001), whereas the LP led to greater anteroinferior translations in these same positions (p = 0.002 and p = 0.014, respectively). The SSP outperformed the LP under inferior loading in neutral (p = 0.005) and abduction (p = 0.02) positions, though it did not fully restore stability to native shoulder levels. The SSP maintained ROM similar to native shoulders. LP allowed greater ROM, potentially compromising stability. Conclusion: The SSP provided greater stability than the open Latarjet in most positions and did not limit ROM, suggesting it could be a viable, less invasive option for managing shoulder instability. Level of Evidence: Not applicable.

Comparing postoperative proprioception of the glenohumeral joint between the open and the arthroscopic Latarjet procedure.

BACKGROUND: Shoulder proprioception, in which the anterior glenohumeral capsule plays a major role, is critical to the functioning of the shoulder. Consequently, most surgeons either do not resect or reinsert the anterior capsule in shoulder stabilization surgery. In the original open Latarjet procedure (OLP), the anterior capsule is preserved. However, in the all-arthroscopic Latarjet procedure (ALP), complete anterior capsule resection is recommended for better view and access to the coracoid. This raises the question if there is a postoperative difference in proprioception between these 2 procedures. Therefore, the aims of this study are (1) to assess the difference in postoperative proprioception between the operated and healthy sides after the OLP and ALP and (2) to compare the difference in postoperative proprioception on the operated side between the OLP and ALP. METHODS: We conducted a retrospective analysis including all patients who underwent a proprioception test after an OLP or ALP at our center. Collected baseline characteristics included sex, age at surgery, operated side, hand dominance, presence of a Hill-Sachs lesion, and time between surgery and the proprioception test. For the test, patients were positioned 1 meter from a wall. They were blindfolded and had to point at a target with a laser pointer taped to their index finger. The laser point was marked and the errors were measured horizontally and vertically and categorized as <4 cm, 4-8 cm, 8-16 cm, and >16 cm. RESULTS: Between April 2022 and April 2024, a total of 91 cases were identified, of which 24 underwent an OLP and 67 underwent an ALP. No significant difference was found in error distribution between the healthy and operated side after both the OLP (P = .30 horizontally, P = .67 vertically) and ALP (P = .20 horizontally, P = .34 vertically). Moreover, there was no significant difference in error distribution between the operated sides after the OLP vs. ALP (P = .52 horizontally; P = .61 vertically). CONCLUSION: Our data suggest that postoperative proprioception is not significantly different between the operated and healthy sides after both the OLP and ALP, nor between the operated sides after the OLP vs. after the ALP. This might imply that completely resecting the anterior glenohumeral capsule does not have a detrimental effect on shoulder proprioception. However, these results are multifactorial and prospective studies are needed to better understand the regeneration potential of glenohumeral capsule mechanoreceptors and the importance of the anterior capsule for shoulder proprioception.

Results of combined all-arthroscopic Latarjet with Hill-Sachs remplissage for significant bipolar glenohumeral bone loss.

BACKGROUND: Arthroscopic Latarjet using suture-button fixation has shown good clinical results and low recurrent instability in patients with significant glenoid bone loss. However, the presence of an associated Hill-Sachs lesion (HSL) is a risk factor for recurrent instability after isolated Latarjet. The aim of the study was to report clinical and radiologic results following all-arthroscopic Latarjet combined with Hill-Sachs remplissage (HSR). METHODS: Monocentric prospective study including 41 patients (mean age 28 ± 7 years) who underwent the combined procedure between 2014 and 2019 with minimum 2 years' follow-up (mean 40 ± 13 months). Indications were glenoid bone loss >10% (mean 23.9% ± 7.5%) and large, deep HSL (Calandra 3). Five (13%) patients had signs of osteoarthrosis stage I preoperatively, 4 (10%) had previous stabilization surgery (3 cases isolated Bankart and 1 case Bankart combined with HSR), and 4 (13%) were epileptic. The HSR was performed first followed by guided Latarjet procedure. Primary outcome measures included shoulder stability and function represented by Walch-Duplay and Rowe scores, and Subjective Shoulder Value (SSV) for daily life/sports. Secondary outcome measures included coracoid graft position and union, and glenohumeral osteoarthritis using radiographs and computed tomography. RESULTS: Three patients (7%) had recurrent instability: 1 due to seizure, 1 following fall, and 1 related to graft osteolysis. Two patients were revised because of recurrence with arthroscopic distal clavicle autograft. There were no infections, neurologic complications, or hardware failures. The Walch-Duplay score was 90 (95% CI 76.8-93.2), and the Rowe score 95 (95% CI 77.2-92.2). The median SSV averaged 96% (95% CI 87.5-97.0) for daily life and 90% (95% CI 75.7-90.2) for sports. Mean external rotation with the arm at the side was 60° (95% CI 59°-70°) with a median loss 10° (95% CI 3°-17°) compared to the contralateral side. Among patients playing sport preoperatively, 36 (95%) were able to return to sport: 25 (67%) at the same level and 7 (18%) at a lower level, whereas 4 had to change sport. The coracoid graft was flush with the glenoid surface in 96% of cases and subequatorial in 89%. The graft developed nonunion in 11% and fractured in 5%. Seven patients (18%) had radiographic signs of grade I osteoarthritis. CONCLUSION: Combined arthroscopic Latarjet and HSR is an efficient solution for dealing with significant bipolar glenohumeral bone loss. The combined procedure deserves consideration in high-risk patients including combined bone loss, recurrent anterior instability after failed stabilization procedures and/or seizure.

Comparison of Modified Latarjet Procedure With Bone Graft Versus Standard Latarjet Procedure: Evaluating Outcomes and Stability.

BACKGROUND: The Latarjet procedure is a well-established technique for managing repeated anterior shoulder dislocation accompanied by massive glenoid bone loss. Aim of this article was to assess outcomes among modified Latarjet procedure using allograft from Iliac bone and a standard Latarjet procedure using the coracoid process. METHODS: Six patients with recurrent anterior shoulder instability and significant glenoid bone loss were retrospectively analyzed. Three patients underwent the modified Latarjet procedure with iliac crest bone graft (Group A), and three underwent the standard Latarjet procedure (Group B). Outcomes were assessed at the 12-month follow-up, including shoulder stability, functional scores (Constant, the American Shoulder and Elbow Surgeons (ASES) score, and the Western Ontario Shoulder Instability Index (WOSI)), range of motion, complications, and return to sports. RESULTS: Both groups showed improvements in stability and functional scores, with no recurrent instability reported. Group A demonstrated slightly higher functional scores and range of motion. One patient in Group A experienced donor site pain, while one patient in Group B showed significant graft resorption. Graft union was achieved in all patients. Two-thirds of patients in each group returned to their pre-injury level of sports participation. CONCLUSION: Both techniques provided good clinical outcomes for anterior shoulder instability with glenoid bone loss. The modified Latarjet with iliac crest graft may offer slight advantages in functional outcomes and graft preservation but is associated with potential donor site morbidity. Larger, prospective studies are needed to definitively compare these techniques.

Management of Neglected Locked Anterior Shoulder Dislocation in the Elderly Population in an Indian Scenario - A Case Report.

Introduction: There is a paucity of literature regarding a neglected shoulder dislocation, as it is unusual to miss it clinically due to the apparent deformity. Nevertheless, in some cases, particularly those who receive primary treatment from a local bonesetter, they may present with a neglected shoulder dislocation. In the absence of comprehensive studies, health-care professionals have to resort to lower-tier evidence and practical experience to guide their treatment decisions. Therefore, most of the treatment recommendations are based on level four studies and the literature for recurrent dislocation of the shoulder. Case Report: We have described three cases of neglected anterior dislocation of the shoulders in two patients, which were managed by open reduction, Latarjet procedure, remplissage, and rotator cuff repair. Both of our patients after 1-year follow-up had a painless joint with an improved functional range of motion. This case discussion contributes to understanding the approach to treating these patients. Conclusion: Recurrent shoulder joint instability with bone loss in the younger and older age groups has to be managed differently. Based on this case report involving individuals older than 50 years, it can be inferred that the approach to managing neglected locked shoulder dislocations with off-track lesions is with open reduction and fixation with Latarjet procedure, coupled with RCR and remplissage, has yielded adequate joint stability and favorable post-operative outcomes.

Association of the Inlay Structure Used in the Modified Bristow Procedure With Accelerated Bone Union: Comparing the Cuistow and Modified Bristow Procedures.

Background: The Chinese unique inlay Bristow (Cuistow) procedure is a modified Bristow surgery in which an inlay (mortise-and-tenon) structure is added to the contact surface between the coracoid tip and the glenoid. Patients who have undergone the Cuistow procedure have had satisfying clinical performance and excellent postoperative bone healing rates (96.1%). Purpose: To compare the clinical and radiographic outcomes after the arthroscopic Cuistow procedure and the arthroscopic Bristow procedure. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 91 patients who underwent either the Cuistow or Bristow procedure between January 2017 and March 2018 were selected, and 69 patients (70 shoulders; 35 in the Cuistow group and 35 in the Bristow group) were included. Clinical assessment at minimum 24 months postoperatively, including the visual analog scale for pain and instability, American Shoulder and Elbow Surgeons score, Rowe score, subjective shoulder value score, and active range of motion, was completed by independent observers and compared with values collected preoperatively. Assessment with 3-dimensional computed tomography scans was performed preoperatively; immediately after the operation; at 3, 6, and 12 months postoperatively; and at the final follow-up. Results: A total of 69 patients (70 shoulders) were included, with a mean follow-up duration of 34.41 ± 5.99 months (range, 24-50 months). Both groups saw significant improvement in visual analog scale for pain and instability, American Shoulder and Elbow Surgeons, Rowe, and subjective shoulder value scores at the final follow-up compared with the preoperative values (P < .001 for all), with no significant between-group differences on any clinical outcomes at the final follow-up. The 3-month postoperative graft union rate on computed tomography was significantly higher in the Cuistow group compared with the Bristow group (82.9% vs 51.4%, respectively, P = .003), although the graft union rate at the final follow-up was not significantly different (94.3% vs 85.7%, respectively; P = .449). Conclusion: Patients receiving the Cuistow procedure had equivalent clinical outcomes and a significantly higher bone union rate at 3 months postoperatively than those in the Bristow group. The inlay structure used in the Cuistow procedure was found to be associated with accelerated bone union.

Clinical and radiological outcome following arthroscopic Latarjet with cerclage FiberTape fixation with a minimum 1-year follow-up.

Background: The rates of implant-related complications are significant following the Latarjet procedure using metal screws in patients with recurrent shoulder dislocation and bone loss. The purpose of this study is to evaluate the short-term outcome following the arthroscopic Latarjet procedure using cerclage FiberTape (Arthrex, Naples, FL, USA) combined with remplissage and capsulolabral repair. It was hypothesized that performing the procedure with cerclage FiberTape would provide sturdy fixation, comparable to the conventional method of using metal screws, while averting hardware-related complications attributed to the latter in published literature. Methods: A prospective study was performed in a single institution between 2020 and 2022, with all surgeries performed by a single fellowship-trained shoulder surgeon who has ample experience in performing arthroscopic screw Latarjet procedures. Patient demographics, number of dislocations before surgery, arm dominance, ligamentous laxity, type of sporting activity, Instability Severity Index Score, and percentage of bone loss on the glenoid and humeral sides were recorded. The patients were followed up with visual analog scale, American Shoulder and Elbow Surgeons score, Rowe score, and Walch-Duplay score preoperatively and postoperatively. The coracoid graft position, healing, and remodeling were assessed with computed tomography scans at 3 months postoperatively. Minimum clinical follow-up was for a period of one year. Results: Overall, 10 patients (all males, average age 28 ± 8.8 years) were operated on with an arthroscopic Latarjet procedure using cerclage FiberTape. The minimum follow-up period was 12 months, and the mean follow-up was 13.2 months. The median and individual visual analog scores during arm motion, American Shoulder and Elbow Surgeons scores, Rowe scores, and Walch-Duplay scores improved in the follow-up period. Computed tomography scans at 3 months showed flushed graft position in 5 patients, medial graft position in two patients, and three patients showed graft nonunion with migration. Out of 10 patients, seven had good graft union in follow-up scans. None of the patients required revision surgery. All three patients with graft nonunion were kept under follow-up beyond the study period for recurrence of instability. Conclusion: Our study demonstrated that arthroscopic Latarjet using cerclage FiberTape fixation combined with remplissage and capsulolabral repair resulted in high rate of graft loosening and migration (30%). Nonetheless, patients in whom the coracoid graft had united, as well as those in whom it had not, all had good to excellent functional and clinical outcomes, no complications, and did not require any revision surgery.

The Arthroscopically Guided Bristow-Latarjet Procedure With Cortical Button Fixation: A Minimum 10-Year Follow-up.

BACKGROUND: Despite improved visualization, the use of arthroscopic surgery to perform the Latarjet procedure has not decreased the rates of complications and glenohumeral osteoarthritis (OA) in the long term. Many of the reported complications are related to the use of screws for bone block fixation with freehand drilling. PURPOSE: To evaluate the long-term (at a minimum 10-year follow-up) clinical and radiological outcomes of the arthroscopic Bristow-Latarjet procedure using a posterior guided drilling technique and suture button for coracoid bone graft fixation. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Consecutive patients who underwent the arthroscopic Bristow-Latarjet procedure with suture button fixation between 2011 and 2013 were reviewed by 2 independent evaluators. Complications and revision surgery were recorded, and we evaluated patient-reported outcomes including subjective scores, recurrence of shoulder instability (dislocation or subluxation), range of motion limitations, and return to sports. Patients had radiographs taken at least 10 years after surgery to assess glenohumeral OA according to the Samilson-Prieto classification system and computed tomography scans to assess bone block positioning and healing. RESULTS: A total of 65 consecutive patients (68 shoulders) with a mean follow-up of 135 months (range, 120-156 months) were included. The mean age at the time of surgery was 25 ± 8 years; 7 patients had previous failed Bankart repair. At follow-up, 94% (64/68) of the shoulders had no recurrence of instability. The 4 cases of instability recurrence were traumatic and occurred at 3 weeks (a fall), 4 months, 2 years, and 7 years after surgery. No hardware failures, coracoid fractures, or neurological complications were observed. Overall, 61 patients (94%) were still participating in sports, with 44 (68%) at the same or higher level. Range of motion showed nonsignificant restrictions in external rotation with the arm at the side (7° ± 9°) and with the arm at 90° of abduction (9° ± 10°) compared with the contralateral side. Additionally, 11 shoulders (16%) had some residual anterior apprehension on clinical examination. At last follow-up, 77% (47/61) of the shoulders had no OA development or progression. Previous failed Bankart repair was a risk factor for the development of OA. Patients with OA had significantly lower Subjective Shoulder Value scores (79% vs 91%, respectively; P = .01) and decreased external rotation with the arm at the side (40° vs 65°, respectively; P = .001) compared with patients with no or little OA. CONCLUSION: The arthroscopically guided Bristow-Latarjet procedure with suture button fixation is a safe and durable surgical treatment method for recurrent anterior shoulder instability, allowing a high rate of return to sports without significant motion restrictions and no or little OA in the long term.

Open Bone Augmentation Solutions for the Failed Shoulder Stabilization.

Utilizing fresh distal tibia allograft in anterior glenoid reconstruction has emerged as a highly advantageous approach in addressing instances of failed anterior shoulder stabilization with glenoid bone loss. This procedure offers several benefits, including the absence of donor-site morbidity, restoration of significant glenoid defects, reestablishment of joint congruity with the humeral head, restoration of glenoid biomechanics, and the addition of cartilage to the glenoid. Furthermore, it provides a robust and reliable alternative for managing failed stabilization procedures, leading to improved clinical outcomes and a high graft healing rate, while maintaining a low occurrence of recurrent instability.

Decision Making of the In-season Athlete with Anterior Shoulder Instability.

In-season management of anterior shoulder instability in athletes is a complex problem. Athletes often wish to play through their current season, though recurrent instability rates are high, particularly in contact sports. Athletes are generally considered safe to return to play when they are relatively pain-free, and their strength and range of motion match the uninjured extremity. If an athlete is unable to progress toward recovering strength and range of motion, surgical management is an option, though this is often a season-ending decision.

The Latarjet Procedure for Recurrent Anterior Shoulder Instability in the Contact Athlete.

In young athletes, anterior shoulder instability is a prevalent condition. Because of high-energy traumas, contact athletes often suffer recurrent instability, bone loss and postoperative recurrences. Patients younger than 20 years, symptomatic for more than 6 months, with ≥ 2 dislocations, with off-track Hill-Sachs lesion, glenoid bone loss, ALPSA lesion, Instability Severity Index Score > 3, and Glenoid Track Instability Management Score > 3 are at higher risk of failure. In cases of multiple dislocations with critical or subcritical glenoid bone loss, notably in collision and contact athletes, the Latarjet procedure is widely recognized as the treatment of choice.

Surgical options and clinical outcomes following a failed Latarjet procedure: a systematic review.

BACKGROUND: A failed prior Latarjet procedure can be a challenging situation for both patients and surgeons. The purpose of this study was to report on the techniques and outcomes of patients undergoing revision surgery for the treatment of recurrent anterior shoulder instability after a failed Latarjet procedure. METHODS: A systematic review was performed by searching PubMed, the Cochrane Library, and Embase to identify clinical studies which reported on surgical techniques for a failed Latarjet procedure with reporting of clinical outcomes. The search terms used were Latarjet failed. Patients were evaluated based on revision method, patient-reported outcome measures (PROMs), reoperation rates, recurrent instability, overall satisfaction, and return to sports and work. RESULTS: Thirteen studies (all Level IV evidence) met inclusion criteria, including a total of 293 shoulders with a mean age of 28.3 years (range, 16-55 years) at the time of surgery. The mean follow-up time was 50.4 months (range, 14.0-208.0 months) and males accounted for 78.6% of all patients. Revision procedures included open and arthroscopic Eden-Hybinette, distal tibial allograft, iliac crest autograft, osteochondral glenoid allograft, and Bankart repair and/or capsular plication. These may all be viable techniques for revision surgery for a failed Latarjet procedure. All revision procedures showed improvements in PROMs including the Visual Analogue Scale, Constant score, subjective shoulder value, Walch-Duplay, and Rowe scores. Return to sports ranged from 46.1% to 94%. Recurrent instability rates ranged from 0% to 43.8%. Reoperation rates ranged from 0% to 31.3%. Overall satisfaction following a revision procedure ranged from 80% to 100%. CONCLUSION: A failed Latarjet procedure can be treated with various revision procedures such as open and arthroscopic Eden-Hybinette, distal tibial allograft, iliac crest autograft, osteochondral glenoid allograft, and Bankart repair and/or capsular plication. Overall, surgical management of the failed Latarjet results in improvements in PROMs, pain, return to sports, and decreased recurrent instability with a moderate complication rate.

Surgical treatment of anterior glenohumeral instability: a historical review.

BACKGROUND: Glenohumeral instability is a common pathology, particularly in young, active patients. METHODS: A narrative review was performed to describe the history of surgical treatments for anterior shoulder instability. RESULTS: Open surgical techniques were first described by Bankart in 1923. Techniques include both anatomic soft tissue repairs and nonanatomic procedures to provide constraint to motion and dislocation. Osseous techniques to address glenoid bone loss include both autograft techniques, such as the Latarjet procedure, and the use of various allografts. Technologic advances, particularly arthroscopy, have continued to drive the evolution of treatments. The concept of the glenoid track has furthered our understanding of this pathology to guide appropriate treatment to reduce recurrence. CONCLUSIONS: Surgical treatment for anterior shoulder instability continues to evolve in an effort to restore function and prevent additional injury.

High Rate of Return to Sport in Contact and Collision Athletes After Arthroscopic Latarjet With Cortical Button Fixation.

BACKGROUND: Contact and collision athletes face a higher risk of recurrent anterior shoulder instability after surgical stabilization. The Latarjet procedure is often preferred given the high incidence of bony lesions. However, this stabilizing procedure, performed either open or arthroscopically, is met with concerns regarding complications and revision surgery rates. PURPOSE: To evaluate the return to sport (RTS) and assess complication and instability recurrence rates in contact/collision athletes undergoing the arthroscopic Latarjet procedure using a guided technique with suture buttons for coracoid fixations. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A retrospective analysis was conducted on contact/collision athletes who underwent the arthroscopic Latarjet procedure for recurrent anterior shoulder instability between January 2011 and March 2018. All patients were operated on arthroscopically using glenoid and coracoid guides and suture button fixation of the transferred coracoid. RTS was defined as the patient being able to participate in his or her activity without any restriction postoperatively. Two independent observers assessed patients using postoperative computed tomography (CT) scans to evaluate coracoid positioning and healing. A multivariate analysis was performed to identify predictive factors associated with persistent apprehension. A group comparison was performed to assess RTS failure risk factors. RESULTS: In 136 contact/collision athletes (mean age, 25 ± 7 years), 93% were satisfied, and 98% achieved shoulder stability at a mean follow-up of 60 months (range, 24-117 months). No suture button-related complications or neurovascular issues were reported. Overall, 82% (112/136) returned to contact/collision sports. The mean time to RTS was 5.3 ± 1.2 months (range, 3-7.3 months). In a CT study performed 2 weeks after surgery, 87% (118/136) of bone grafts were positioned below the equator and 93% (126/136) were flush to the glenoid surface. At the 6-month postoperative CT examination, complete bone block healing was achieved in 84% (114/136). On clinical examination at the latest follow-up, 36 patients (26%) reported some anterior apprehension on testing. On multivariate analysis, patients with severe humeral bone defects (medium to large Hill-Sachs lesions, Calandra grade 2 or 3) had a higher risk of postoperative persistent apprehension. On group comparison, a visual analog scale score >3 and persistent anterior apprehension were found to be associated with failure of RTS. CONCLUSION: The arthroscopic Latarjet procedure with suture button fixation allowed 82% of athletes with recurrent anterior shoulder instability to return to contact or collision sports. Patients with severe humeral bone defects have a higher risk of persistent anterior apprehension and decreased RTS. The arthroscopic-guided procedure with suture button fixation is safe; accurate, with a high rate of anatomic graft positioning and healing; and reliable, with a low recurrence rate.

Good clinical outcomes and low recurrence rate in patients undergoing arthroscopic revision Latarjet for failed arthroscopic Bankart repair.

BACKGROUND: The role of arthroscopic Latarjet stabilization after failed arthroscopic Bankart repair has yet to be definitively established and merits further investigation. OBJECTIVE: To assess clinical and radiological outcomes after arthroscopic Latarjet stabilization as a revision procedure for failed Bankart repair, as well as the return to athletic activity and complication rates. METHODS: Between 2009 and 2020, patients with a previous failed arthroscopic Bankart repair who were treated with an arthroscopic Latarjet were retrospectively evaluated. Clinical outcomes at a minimum of 24 months postoperatively included the Rowe score, Western Ontario Shoulder Instability Index, Constant-Murley Shoulder Outcome score, and Single Assessment Numeric Evaluation. Dislocations, subluxations, complications, pre- and postoperative levels of activity, and degree of osteoarthritis were also assessed. RESULTS: A total of 77 patients, with a mean age at revision surgery of 31.2 ± 9.1 years and with either 1 (n = 59), 2 (n = 13), or 3 (n = 4) previous arthroscopic stabilizations, who underwent revision surgery using an arthroscopic Latarjet procedure were studied. Postoperatively, the mean Rowe and Constant-Murley Shoulder Outcome scores increased from 41.8 ± 16 to 90.7 ± 14.3 (P < .001) and from 50.5 ± 13.8 to 90.5 ± 10.3 (P < .001), respectively. Western Ontario Shoulder Instability Index decreased from 1247 ± 367.6 to 548.9 ± 363 at the final follow-up (P < .001). After a mean follow-up of 39.6 ± 23.1 months, 64 shoulders (83.1%) were subjectively graded as good to excellent using the Single Assessment Numeric Evaluation score. Grade 1, 2, and 3 osteoarthritis, according to Ogawa et al, was found in 18 (23.4%), 6 (7.8%), and 3 (3.9%) shoulders, respectively. Six (7.8%) dislocations after revision surgery were reported. In 4 failed cases, an Eden-Hybinette procedure was conducted, and in the remaining 2 patients, an arthroscopic extra-articular anterior capsular reinforcement was performed. A significantly decreased level of athletic activity was observed postoperatively (P = .01). CONCLUSIONS: Arthroscopic Latarjet for the revision of failed arthroscopic Bankart repair provides satisfactory patient-reported subjective outcomes with a low rate of recurrences and complications. However, a decreased level of athletic activity is expected.
