Low rates of serious complications after open Latarjet procedure at short-term follow-up

To report on intraoperative and short-term postoperative adverse events after open Latarjet procedure in patients with recurrent anterior shoulder instability. These complications were classified into different grades of severity based on the treatment required and the learning curve of the procedure. Ninety-six patients (102 shoulders) underwent open Latarjet procedure for recurrent post-traumatic anterior glenohumeral instability between 2012 and 2020. The minimum duration of patients' follow-up was 6 months. Adverse events were classified into 3 classes based on the severity and subsequent treatment. The complications in the first 50% of all cases were compared with the latter 50% to evaluate the role of learning curve on the complication rates. The mean follow-up was 7.2±2.8 months. The patients' mean age was 26.7±8.9 years and consisted of 83 (86.4%) male and 13 (13.6%) female patients. The total adverse events rate was 18.6%. Adverse events requiring no additional treatment (class 1) occurred in 6 cases (5.8%) including fibrous union (3.9%) and asymptomatic resorption of the graft (1.9%). Adverse events requiring additional or extended nonoperative management (class 2) occurred in 8 cases (7.8%), including coracoid fracture (2.9%), musculocutaneous nerve palsy (1.9%), axillary nerve palsy (0.9%), suprascapular nerve palsy (0.9%), and stiffness (0.9%). All the nerve palsies recovered without long-term sequelae. Adverse events requiring secondary operative procedures (class 3) occurred in 5 cases (4.9%), including symptomatic hardware (1.9%), medial healing of the graft (0.9%), screw loosening (0.9%), and deep infection (0.9%). The rate of adverse events in revision cases was higher than primary cases in 11.7% and 6.8%, respectively (P=.119). The complication rate was significantly higher in the first half of the surgeons' practice (14.7%) than in the second half (3.9%) (P ≤ .05). The overall complication rate reported in this open Latarjet series is 18.6%; however, the rate of class 3 adverse events that required additional surgery or long-term medical treatment was only 4.9%. Revision cases had a higher rate of complications than primary cases, and the learning curve has had a significant impact on the rate of adverse events.

Anterior Shoulder Instability in a Young Individual with Concomitant Coracoid Process Fracture Treated with the Latarjet Procedure – A Rare Case Report

Coracoid fracture occurs with shoulder instability due to direct humeral head impaction. Incidence coracoid fracture with shoulder dislocation is rare amounts to 0.8-2%. We encountered clinical challenge of unique combination of both shoulder instability and coracoid fracture. This technical note will describe the treatment of the same. A 23-year-old male suffering from recurrent shoulder dislocation sustained coracoid fracture. Further evaluation showed glenoid defect of 25%. Magnetic resonance study showed on track lesion with Hill-Sach lesion of 9 mm, labral defect anteriorly with no associated rotator cuff tear. The patient was managed with open Latarjet procedure with fracture coracoid fragment with conjoint tendon as graft. Our purpose of reporting this technical note is to provide an option of dealing both instability and coracoid fracture in single sitting and usage of coracoid fractured fragment as an excellent graft of choice in acute presentation. However, certain limitations such as adequacy of graft in size and shape do exist operating surgeon which must be aware of the same.

Complications of the Open Latarjet Procedure are not Related to the Learning Curve: Analysis after 11 Years of Experience

Introduction: The purpose of this study is to determine a relationship between complications of the open Latarjet procedure with the surgeon’s learning curve during an 11-year experience in shoulder surgery. Methods: We conducted a retrospective descriptive observational case series of all open Latarjet procedures performed by a single shoulder surgeon between June 2011 and September 2021. Latarjet procedure was indicated in patients with glenoid bone defects of more than 15% or revision after a failed Bankart repair. Complications were recorded as well as patients’ demographic data. We described the time between surgery and complication and correlated complication presentation with the surgeon’s surgical curve. Results: Sixty-two consecutive patients were included (96, 8% male patients with an average age of 30 years). Eight patients presented with a complication (12, 5% of all patients). These complications were classified as graft related (n = 3), hardware related (n = 3), wound related (n = 1), and other (n = 1). There were no instability recurrences and no neurologic injuries. Complications were present in all periods of the surgeon’s learning curve. Conclusions: The Latarjet procedure is technically demanding and complications can be present regardless of the surgeon’s learning curve. Nevertheless, it is a successful procedure in most patients, with a low recurrence rate of instability.

Functional Outcome of Open Latarjet Procedure for Recurrent Anterior Shoulder Dislocation

OBJECTIVES To find the functional outcome of the open Latarjet method for recurrent anterior shoulder dislocation. METHODOLOGY The current retrospective study was conducted at the Orthopedic and Trauma Department of the Khyber Teaching Hospital in Peshawar from September 2020 to August 2021. A total of 31 patients were included in the study, of which 29 were males and 2 were females. A detailed medical history was obtained through physical examination, and all necessary laboratory tests were requested. AP and axillary views of plain X-ray radiographs were taken. We used a CT scan on all the patients to calculate the humeral and glenoid bone loss. We had all patients undergo an MRI to rule out soft tissue pathology. Six months after surgery, the outcome was graded using the Constant Murley Score on a good, good, fair, and poor scale. RESULTS In this study open Latarjet procedure was done in 31 patients with 29 males (93.4%) and two females (6.45%). The right-sided shoulder was involved in 24 (77.14 %) patients, while the left shoulder was involved in 7 patients (22.58%). A bipolar lesion in the shoulder with bone loss was seen on the glenoid side at 17.5% (range 10-25%), and the humeral side was 22.5%. Follow-up was done for six months in which 22 patients had a very good outcome (70.96%), six patients had a good outcome(19.35%), two patients had a fair outcome(6.45%), and one patient had a poor outcome(3.22%). There were no major complications seen like graft fractures, graft malposition, neurovascular compromise, and hardware breakage CONCLUSION Recurrent anterior shoulder instability can be effectively treated with open Latarjet with excellent functional outcomes and a very low complication rate and recurrence.

Long-term outcomes of anterior shoulder instability treated with open latarjet procedure - a systematic review of outcomes at a minimum 15-year follow-up.

To systematically review the literature to evaluate the outcomes following an open Latarjet (OL) procedure at a minimum 15-year follow-up. Two independent reviewers performed a literature search using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using 3 databases. Only studies reporting outcomes of OL procedure with a minimum of 15 years of follow-up were included. Nine studies composed of 326 shoulders (78.2% males) in 313 patients were included (average age 26.9 ± 3.2 years (15-58)), with a mean follow-up of 271.9 ± 69.2 months (180-420) At a minimum 15-year follow-up, 93.5% (286 of 306) patients reported being satisfied with their OL procedure, whilst 86.8% (177 of 204) reported good/excellent outcomes at final follow-up. All nine of the included studies reported an overall rate of recurrent instability was 7.7%, with re-dislocations and subluxation at 3.4% and 5.8%, respectively. The rate of surgical revision was 5.15%; 3.5% of cases were revised for recurrent instability. Instability arthropathy was reported across all included studies as 41.0%. The OL procedure results in satisfactory clinical outcomes, low rates of recurrent instability and surgical revision at a minimum 15-year follow-up. Although high levels of radiological instability arthropathy and residual pain are found over the same period, these appear stable from a minimum of 10-year follow-up data. IV; a systematic review of all levels of evidence.

The Short, 5-Item Shoulder Instability–Return to Sport After Injury Score Performs as Well as the Longer Version in Predicting Psychological Readiness to Return to Sport

To reduce the length of the Shoulder Instability-Return to Sport After Injury (SIRSI) scale and determine the predictive validity of the short version compared with the original form. This study included patients who underwent an arthroscopic Bankart repair or open Latarjet procedure between 2017 and 2019. One group was used for the SIRSI scale-reduction process, and a second group was used to test the predictive validity of the proposed short SIRSI scale. The Cronbach α value was used to evaluate internal consistency. Validity was determined by calculating the Pearson correlation coefficient with the Western Ontario Shoulder Instability Index scale. Predictive validity was assessed using receiver operating characteristic (ROC) curve statistics. A total of 158 patients participated in the scale-reduction process, and 137 patients participated in the predictive-validation process. The SIRSI scale was successfully reduced to a 5-item scale constructed by 1 underlying factor accounting for 60% of the variance. The short version showed good internal consistency (Cronbach α= 0.82) and was highly correlated with the Western Ontario Shoulder Instability Index scale and the long version. The short SIRSI scores were significantly different between patients who returned to sports and those who did not. The SIRSI scale had excellent predictive ability for return-to-sport outcomes (area under ROC curve of 0.84 for short version [95% confidence interval, 0.7-0.9] and 0.83 for long version [95% confidence interval, 0.7-0.9]). A valid 5-item, short version of the SIRSI scale was successfully developed in our patient population. Theshort version was found to be as robust as the long scale for discriminating and predicting return-to-sport outcomes. Level II, prospective cohort study.

Surgical treatment of post-traumatic instability of the shoulder joint in athletes

BACKGROUND: Surgical treatment of post-traumatic instability of the shoulder jointinvolves the use of various surgical techniques: open Latarjet procedure, BristowLatarjet operation, which was first performed in Russia at CITO named after N.N. Priorov, the founder of the clinic for sports and ballet trauma, Professor Zoya S. Mironova, also use soft tissue stabilization with anchors, etc. However, in recent years, the Latarjet arthroscopic operation has become a priority choice in the treatment of post-traumatic instability of the shoulder joint.
 AIM: To improve the results and reduce the frequency of postoperative complications, reduce the time of surgical intervention, as well as evaluate the technical difficulties, nuances and improve the surgical technique when performing the arthroscopic Latarjet procedure in professional athletes and amateurs with post-traumatic defects of the shoulder joint.
 MATERIALS AND METHODS: During the period from 2015 to 2021, 50 Latarjet arthroscopic procedure were performed in athletes with post-traumatic defects of the glenoid cavity of the scapula.
 RESULTS: To improve postoperative results, during the Latarjet arthroscopic operation, when positioning the bone autograft, we focused on the 5 oclock in the anterior inferior section of the glenoid cavity of the scapula, which allowed us to maintain the range of motion, namely abduction, flexion and external rotation and bring it almost to the previous level in 96% of patients, the pain syndrome also regressed to 0.80.21 points. Fixation of the capsular-ligamentary apparatus exarticularly allowed to reduce the likelihood of relapse, fracture of the bone autograft, and the development of deforming osteoarthritis of the shoulder joint in the near future.
 CONCLUSIONS: The arthroscopic Latarjet procedure in the treatment of post-traumatic injuries of the shoulder joint is gaining popularity due to the fact that, using low-traumatic approaches, it is possible to correctly position the bone autograft on the anterior-inferior region of the articular surface of the scapula, without subsequent restrictions on the functional component of the shoulder joint.

Subscapularis management during open Latarjet procedure: does subscapularis split versus tenotomy matter? A systematic review and meta-analysis.

The purpose of this study was to systematically review the literature to ascertain the clinical outcomes of the open Latarjet (OL) procedure using either a subscapularis-split (SS) or subscapularis tenotomy (ST) via a deltopectoral (DP) approach. Two independent reviewers performed a literature search using the PubMed, Embase, and Scopus databases according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Only studies reporting on outcomes of the OL procedure via a DP approach comparing both SS and ST were considered for inclusion. Meta-analysis to compare clinical outcomes was performed using RevMan software. Our search found 5 studies that met our inclusion criteria, including 615 shoulders (80.8% male patients), with an average age of 27.8±12.6 years (range, 15-79 years) and mean follow-up period of 50.1±29.4 months (range, 12-180 months). A total of 410 shoulders and 205 shoulders underwent the OL procedure via a DP approach using the ST technique and the SS technique, respectively, with both techniques resulting in significant increases in the Rowe score postoperatively (P<.0001 for both). Additionally, significantly higher postoperative Constant scores were observed in patients who underwent the OL procedure via an SS technique vs. those in the ST group (91.8±7.2 vs. 79.6±16.1, P<.0001). However, meta-analysis showed nonsignificantly higher postoperative Rowe and American Shoulder and Elbow Surgeons scores in patients who underwent the OL procedure via an SS technique vs. those in the ST group (96.1±2.6 vs. 86.4±7.6 [P=.57] and 91.6±1.3 vs. 80.6±25.5 [P=.47], respectively). Furthermore, meta-analysis showed that significantly more patients in the ST group had positive lift-off test results (10.0%) when compared with the SS group at final follow-up (2.7%, P=.01). However, meta-analysis indicated that the rate of recurrent instability was trending toward significance in favor of the SS group (0% vs. 11.7%, P=.07). Our systematic review established that in cases of OL procedures being carried out via a DP approach, the SS technique results in significantly better functional outcome measures and significantly lower rates of subscapularis insufficiency when compared with an L-shaped ST technique at medium-term follow-up. Furthermore, there were lower rates of recurrent instability that were trending toward significance in favor of the SS technique.

Arthroscopic Latarjet With Cortical Buttons Versus Open Latarjet With Screws: A Short-Term Comparative Study

Background: The arthroscopic bone block procedure according to Latarjet remains a controversial subject, and few comparative studies have demonstrated the benefit of arthroscopy over open surgery. Purpose/Hypothesis: The objective of this study was to compare both procedures by analyzing the short-term clinical results. The hypothesis was that the arthroscopic procedure is superior to the standard open procedure. Study Design: Cohort study; Level of evidence, 3. Method: This was a retrospective comparative study. Patients treated for chronic anterior instability by arthroscopic Latarjet with double cortical buttons (group A) or open Latarjet with screws (group O) with a minimum follow-up of 12 months were included. Intraoperative (duration, complications) and postoperative (complications, pain, mobility, functional scores, resumption of sport, Patient and Observer Scar Assessment Scale scar aesthetics, satisfaction) data were compared. Results: In total, 50 patients were included (n = 24 in group A, n = 26 in group O). Operating time was longer in group A (103 vs 61 min; P = .001). The average number of days on analgesics was higher in group A (8.9 vs 5.3 days; P = .04). The complication rate was similar for the 2 groups (12.5% vs 27%; P = .46). At 3 months, the loss of external rotation was greater in group A (–33° vs −18°; P = .01), and resumption of sports was less frequent (11% vs 48%; P = .01). At 12 months, the average scores were excellent, with no significants differences between the 2 groups: Walch-Duplay average, 90 points; Rowe, 94 points; Subjective Shoulder Value (SSV), 92.5%; sport SSV, 85%; and Patient and Observer Scar Assessment Scale score, 17.2 points. Conclusion: Over the short term, this comparative study did not prove the superiority of the cortical-button arthroscopic Latarjet procedure over the open Latarjet procedure. A delay in the resumption of sports, longer time to recover range of motion, and no benefit regarding postoperative pain or the aesthetic aspect of the scar were observed in this study with the arthroscopic procedure.

Open latarjet procedure versus all-arthroscopic autologous tricortical iliac crest bone grafting for anterior-inferior glenohumeral instability with glenoid bone loss.

The purpose of this study is to compare the open Latarjet procedure versus the all-arthroscopic autologous tricortical iliac crest bone grafting (AICBG) technique for recurrent anterior-inferior glenohumeral instability with glenoid bone loss. All open Latarjet and AICBG procedures for recurrent anterior-inferior shoulder instability with glenoid bone loss performed at two institutions between September 2015 and April 2019 were retrospectively analyzed. Inclusion criteria were a traumatic etiology, a glenoid surface deficiency >13.5%, and a minimum follow-up (FU) of 18months. Primary outcomes included the subjective shoulder value, the Western Ontario Shoulder Instability (WOSI), Rowe scores including subdomains, and the four subdomains of the Constant score (pain, activities of daily living, internal rotation, external rotation). Secondary outcomes were subjective shoulder instability, EQ-5D-3L, pain level on the VAS, level of overall satisfaction, operative time, return-to-work rate, and return-to-sports rate. Forty-three patients were available for final analysis (Latarjet: n = 21; AICBG: n = 22) at an average FU of 34.9months (range, 22-66months). Both techniques provided good outcomes and improved stability. The Rowe score, Rowe-range of motion, and CS-internal rotation (p = 0.008, p<0.001, p = 0.001) were slightly better in the AICBG group. Furthermore, the WOSI physical symptoms subdomain was significantly better (p = 0.04) in the AICBG group, while its total score did not reach statistical significance (p = 0.07). There was no statistically significant difference in the secondary outcomes besides operative time, which was significantly shorter in the Latarjet procedure group (p = 0.04). Overall complication rate was similar in both groups (Latarjet: 9.5% (n = 2), AICBG: 9.1% (n = 2)). Open Latarjet and AICBG procedures provide comparable clinical outcomes except for significantly better Rowe score, Rowe-range of motion, WOSI physical symptoms subdomain, and internal rotation capacity in the AICBG group. However, these results should be carefully interpreted in the context of known minimal clinically important differences of these scores.

High rate of return to sport and excellent patient-reported outcomes after an open Latarjet procedure.

The purpose of this study was to report return to sport, patient-reported outcomes (PROs), subjective outcomes, and complications or failures in patients who underwent open Latarjet surgery. Patients who underwent open Latarjet surgery performed by 2 fellowship-trained surgeons between August 2006 and November 2018 were included. Prospectively collected data were reviewed. Recurrent instability and revision surgical procedures were recorded. Subjective outcomes included return to sport and fear of reinjury or activity modification as a result of patients' instability history. PROs included the American Shoulder and Elbow Surgeons (ASES) score, Short Form 12 Physical Component Summary score, Single Assessment Numeric Evaluation score, Quick Disabilities of the Arm, Shoulder and Hand score, and satisfaction. Age, sex, sports participation, pain, primary vs. revision surgery (prior failed arthroscopic or open Bankart repair), dislocation number, glenoid bone loss, glenoid track concept, and projected glenoid track were evaluated. Failure was defined as an ASES score <70, recurrent dislocation, or revision instability surgery. A total of 126 shoulders (125 patients) met the inclusion criteria, with a mean age of 28.1 years (range, 15-57 years). Of 126 shoulders, 7 (5.5%) underwent additional procedures prior to final follow-up and were excluded from outcome analyses; failure occurred in 6 of these shoulders. Mean follow-up data at 3.7 years (range, 2-9.3 years) were attained in 86.6% of patients (103 of 119). All PROs significantly improved from preoperative baseline (ASES score, from 69.7 to 90.2; Single Assessment Numeric Evaluation score, from 55.8 to 85.9; and Quick Disabilities of the Arm, Shoulder and Hand score, from 28.4 to 10.5). PROs did not differ based on sex, sports participation type, dislocation with or without sports, primary vs. revision procedure, and preoperative dislocation number. No correlations existed between PROs and age, glenoid bone loss, or number of previous surgical procedures. On-track lesions (50 of 105, 47.6%) and projected on-track lesions (90 of 105, 85.7%) correlated with better patient satisfaction but not PROs. Despite not having recurrences, 63 of 99 patients (63.6%) reported activity modifications and 44 of 99 patients (44.4%) feared reinjury. These groups had statistically worse PROs, although the minimal clinically important difference was not met. Return to sport was reported by 97% of patients (86 of 89), with 74% (66 of 89) returning at the same level or slightly below the preinjury level. Revision stabilization surgery was required 6 of 126 cases (4.8%), and 6 of 103 shoulders (5.8%) had ASES scores <70. The open Latarjet procedure led to significant improvements in all PROs, and overall, 97% of patients returned to sport. Fear of reinjury and activity modifications were common after open Latarjet procedures but did not appear to affect clinical outcomes. On-track and projected on-track measurements correlated with better patient satisfaction but not improved PROs.

Defining Minimal Clinically Important Difference and Patient Acceptable Symptom State After the Latarjet Procedure

Background: The Latarjet procedure is one of the most well-established treatment options for anterior shoulder instability. However, meaningful clinical outcomes after this surgery have not been defined. Purpose: This study aimed to establish the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) for commonly used outcome measures in patients undergoing the Latarjet procedure and determine correlations between preoperative patient characteristics and achievement of MCID or PASS. Study Design: Case series; Level of evidence, 4. Methods: A multicenter retrospective review at 4 institutions was performed to identify patients undergoing primary open Latarjet procedure with minimum 2-year follow-up. Data collected included patient characteristics (age, sex, sports participation), radiological parameters (glenoid bone loss, off-track Hill-Sachs lesion), and 4 patient-reported outcome measures (collected preoperatively and 2 years postoperatively): the American Shoulder and Elbow Surgeons (ASES) score, the Single Assessment Numeric Evaluation (SANE), the visual analog scale (VAS) for pain, and the Western Ontario Shoulder Instability Index (WOSI). The MCID and PASS for each outcome measure were calculated, and Pearson and Spearman coefficient analyses were used to identify correlations between MCID or PASS and preoperative variables (age, sex, sports participation, glenoid bone loss, off-track Hill-Sachs lesion). Results: A total of 156 patients were included in the study. The MCID values for ASES, SANE, VAS pain, and WOSI were calculated to be 9.6, 12.4, 1.7, and 254.9, respectively. The PASS values for ASES, SANE, VAS pain, and WOSI were 86.0, 82.5, 2.5, and 571.0, respectively. The rates of patients achieving MCID were 61.1% for VAS pain, 71.6% for ASES, 74.1% for SANE, and 84.2% for WOSI. The rates of achieving PASS ranged from 78.4% for WOSI to 84.0% for VAS pain. There was no correlation between any of the studied preoperative variables and the likelihood of achieving MCID or PASS. Conclusion: This study defined MCID and PASS values for 4 commonly used outcome measures in patients undergoing the Latarjet procedure. These findings are essential for incorporating patient perspectives into the clinical effectiveness of the Latarjet procedure and provide valuable parameters for the design and interpretation of future clinical trials.

Poster 135: Minimum 2 year Clinical Outcomes after Latarjet for anterior shoulder instability: clinical and imaging factors that correlate with success or failure

Objectives:The open Latarjet procedure has been demonstrated to be reliable in achieving acceptable patient reported outcomes (PROs). However, clinical predictors of outcome, return to sport and complications/failures have been more variable. The purpose of this study is to report patient reported outcomes (PROs), clinical correlations, and predictors of failure in patients who have received an open Latarjet surgery.Methods:Patients who received an open Latarjet with by two fellowship–trained surgeons between August 2006 - November 2018 were included. Prospectively collected data was reviewed, and PROs included ASES, SF–12 PCS, SANE, QuickDASH, and satisfaction. Age, sex, sports participation, pain, primary vs. revision (prior failed arthroscopic/open Bankart) surgery, dislocation number, glenoid bone loss (GBL), glenoid track concept, and projected glenoid track were evaluated. Projected track was calculated using the axial diameter of the corcoid as part of the glenoid track concept. Postoperative ASES <70, recurrent dislocation, or revision instability surgery were considered failures.Results:126 shoulders (125 patients) met inclusion criteria with mean age of 28.1 years (range 15–57). 7/126 (5.5%) had revision surgery prior to final follow-up and were excluded from outcomes analyses. Mean follow-up 3.7 years (range 2–9.3 years) was attained in 86.6% (103/119) of patients. All PROs significantly improved from preoperative baseline (ASES: 69.7→90.2; SANE: 55.8→85.9; QuickDASH: 28.4→10.5). PROs did not differ with sex, sport participation type, dislocation with/without sports, primary/revision, and preoperative dislocation number. No correlations existed between PROs and age, GBL, or number of previous surgeries. On-track (50/105, 47.6%) and projected on-track (90/105, 85.7%) lesions correlated with better patient satisfaction, but not PROs. A total of 97% (86/89) returned to sport, with 74% (66/89) at the same/slightly below pre-injury level. Failures included 13/126 (10.3%) postoperative dislocations and 6/126 (4.7%) with ASES scores <70.Conclusions:The open Latarjet procedure lead to significant improvements in all PROs, and overall 97% of patients returned to sport. On-track and projected on-track measurements correlated with better patient satisfaction, but not improved PROs. No other factors were predictive of outcomes, nor clinically correlated with failure.

Long-term Outcomes After the Open Latarjet Procedure for the Surgical Management of Humeral Avulsion of the Glenohumeral Ligament Lesions

Background: Recurrent anterior glenohumeral instability caused by a humeral avulsion of the glenohumeral ligament (HAGL) lesion has been studied, but very limited long-term evidence is available. Purpose: To retrospectively review patients with a HAGL lesion who underwent an open Latarjet procedure for recurrent anterior shoulder instability. Study Design: Case series; Level of evidence, 4. Methods: A total of 16 patients with complete clinical and radiological data were available for a review. Clinical outcomes were assessed by range of motion, apprehension testing, the visual analog scale for pain, the Walch-Duplay score, the Rowe score, the Constant-Murley score, the Subjective Shoulder Value, and return to sports. Radiographs were reviewed for osteoarthritis and complications. Results: The median age of patients at the time of surgery was 28 years (range, 18-42 years). All patients were male with no hyperlaxity. The median follow-up time was 10 years (range, 2.8-15 years). Postoperative range of motion showed recovered forward elevation (median, 175°), external rotation (median, 62°), and internal rotation (median, 9 points). Overall, 87% returned to sports, with 68% to the same level and 93% satisfied or very satisfied. Median clinical outcomes were the following: visual analog scale score, 1 (range, 0-2); Walch-Duplay score, 86 (range, 75-100); Rowe score, 95 (range, 90-100); Constant-Murley score, 77 (range, 74-79); and Subjective Shoulder Value, 88% (range, 80%-95%). There were no recurrent dislocations or subluxations. One patient described mild long-term pain, and 1 patient had persistent stiffness. Other complications included 12% with subjective apprehension, 1 patient with a wound infection, and another patient with delayed bone graft union. Additionally, 56% of cases had mild postoperative arthritis at the final follow-up. There were no reoperations. Conclusion: The open Latarjet procedure provided good outcomes with acceptable complication rates in the long term for patients with HAGL lesions. It is an effective treatment option and a safe alternative to arthroscopic or open HAGL repair.

Open Bristow Versus Open Latarjet for Anterior Shoulder Instability in Rugby Players: Radiological and Clinical Outcomes.

Background:Coracoid transfer is a reliable method for managing anterior shoulder instability in athletes who play contact sports; however, differences between the Bristow and Latarjet procedures are unclear.Purpose:To compare clinical outcomes and rates of bone union and bone resorption of the coracoid process between the open Bristow and open Latarjet procedures in rugby players.Study Design:Cohort study; Level of evidence, 3.Methods:Rugby players who underwent an open Bristow or an open Latarjet procedure were retrospectively reviewed for anterior shoulder instability, and 66 shoulders in the Bristow group and 35 in the Latarjet group were included. Graft union and resorption were evaluated using computed tomography at 3 months to 1 year postoperatively. Patient-reported outcome measures (American Shoulder and Elbow Surgeons score, Rowe score, and satisfaction rate) were obtained at a mean follow-up of 74 months (range, 45-160 months) for Bristow and 64 months (range, 50-76 months) for Latarjet procedures. Recurrence and the rate of return to play (RTP), frequency of pain after RTP, and retirement rate after RTP were also assessed.Results:In 97.1% of the Latarjet procedure cases, bone union of the coracoid was achieved at 3 months postoperatively; however, bone union was achieved in only 72.7% of the Bristow procedure cases at 6 months postoperatively. Bone resorption of the coracoid process occurred in 6.1% of shoulders after the Bristow procedure, whereas 100% of shoulders showed bone resorption after the Latarjet procedure. No statistical differences were found in outcome scores between the 2 procedures. Subluxation and persistent pain after returning to sports were identified at a significantly higher rate in the Latarjet group (5 shoulders [14%] and 9 shoulders [26%], respectively) than in the Bristow group (2 shoulders [3%] and 2 shoulders [3%]) (P = .0471 and P = .001, respectively).Conclusion:The Latarjet procedure had an advantage in the early and high rate of bone union but was at a disadvantage in bone resorption compared with the Bristow procedure. Subluxation and pain after returning to sports were more frequent in patients who underwent the open Latarjet procedure than in those who underwent the open Bristow procedure.

Long-Term Results and Failure Analysis of the Open Latarjet Procedure and Arthroscopic Bankart Repair in Adolescents.

The purpose of this study was to analyze the long-term results of arthroscopic Bankart repair compared with an open Latarjet procedure in adolescents who are at high risk for recurrent anterior shoulder instability. We hypothesized that the long-term stability rate of an open Latarjet procedure would be superior to that of arthroscopic Bankart repair. Forty eligible patients (41 shoulders) with a mean age of 16.4 years (range, 13 to 18 years) underwent arthroscopic Bankart repair, and 37 patients (40 shoulders) with a mean age of 16.7 years (range, 14 to 18 years) underwent an open Latarjet procedure. Of these, 34 patients (35 shoulders) in the Bankart group and 30 patients (31 shoulders) in the Latarjet group with long-term follow-up were compared; the overall follow-up rate was 82%. Clinical and radiographic results were obtained after a mean follow-up of 12.2 years (range, 8 to 18 years). Treatment failure occurred in 20 shoulders (57%) in the Bankart repair group and in 2 shoulders (6%) in the open Latarjet procedure group (p < 0.001), representing a significantly higher revision rate for instability in the Bankart group (13) compared with the Latarjet group (1) (p < 0.001). In patients without recurrent shoulder instability (15 in the Bankart group and 29 in the Latarjet group), there was a significant improvement in the Constant score (p = 0.006 in the Bankart group and p < 0.001 in the Latarjet group) and Subjective Shoulder Value (p = 0.009 in the Bankart group and p < 0.001 in the Latarjet group), without any significant difference between the 2 groups. Younger age was the only variable significantly correlated with failure following a Bankart repair (p = 0.01). Adolescents are at a high risk for treatment failure after Bankart repair, and, therefore, the Latarjet procedure should be strongly considered as a primary procedure for recurrent anterior shoulder instability in this population.

Belt and suspender technique for bipolar bone loss in shoulder instability

Bipolar glenohumeral bone loss is a challenging condition to address in patients with recurrent anterior shoulder instability. In this category of patients, most isolated soft-tissue procedures such as remplissage or infraspinatus capsulotenodesis are associated with high risk of failure and instability recurrence. Even bony procedures such as Latarjet may fail to provide absolute stability, and instability may eventually recur. For a better understanding of the cause of failure in this particular type of patient, we may refer to the glenoid track concept which has been described as a useful tool for surgical planning. In fact, Latarjet procedure alone may leave a place for engagement of the Hill-Sachs defect on the anterior glenoid resulting in an off-track situation and secondary glenohumeral instability. In this technical note, we present the combination of arthroscopic remplissage and an open Latarjet procedure to treat patients with bipolar glenohumeral bone loss with good results at 31-month follow-up. Our aim is to propose these techniques as a possible rescue procedure for highly unstable shoulders combining engaged Hill-Sachs lesion and glenoid bone loss of more than 25%. We believe this technique would be a good option for patients who present other risk factors of recurrence such as past medical history of epilepsy, laxity, and psychiatric illnesses.

Primary Open Latarjet Procedure Results in Functional Differences but No Structural Changes in Subscapularis Muscle Quality vs the Healthy Contralateral Shoulder at Long-term Follow-up

Background: There are concerns that the Latarjet procedure results in loss of glenohumeral rotation and strength and in subscapularis dysfunction. The long-term effects of this procedure on subscapularis quality, glenohumeral rotation, and strength are unknown. Purpose/Hypothesis: To analyze the long-term effect of the primary open Latarjet procedure using a muscle-splitting approach on internal and external rotation and strength, as well as subscapularis muscle quality as compared with the healthy contralateral side. We hypothesized that the primary open Latarjet procedure is associated with a reduction of long-term shoulder strength and function and decreased subscapularis quality. Study Design: Case series; Level of evidence, 4. Methods: A total of 42 patients who underwent a primary open Latarjet procedure for recurrent anterior shoulder instability at a mean age of 26 years (range, 18-36) were reviewed after a mean follow-up of 8.4 years (range, 5-12). The subscapularis muscle volume and fat fraction of both shoulders were assessed. Bilateral active internal rotation (IR) and external rotation (ER), as well as IR and ER strength, were assessed by isokinetic testing (concentric, eccentric, and fatigability). Results: Active IR (0.6-point difference, P < .001) and ER (4° difference, P = .010) were significantly greater in healthy contralateral shoulders. The IR strength of the operated shoulder was significantly less than that of the healthy shoulder in concentric and eccentric testing (range of deficit, 4%-6%; P < .05). Also, the ER strength of the operated shoulder was significantly less than that of the healthy shoulder in concentric testing (11% deficit, P < .05). Subscapularis muscle volume was significantly greater in the operated shoulder (4% difference, P = .022), and there was no significant difference in fat fraction (P = .114). Conclusions: The primary open Latarjet procedure was associated with significantly decreased active IR and ER and strength when compared with the healthy contralateral shoulder. The clinical influence of these findings is yet to be defined. There was no increased subscapularis muscle fatty degeneration but a minimal hypertrophy on the operated side at long-term follow-up.

Bone Fragment Resorption and Clinical Outcomes of Traumatic Bony Bankart Lesion Treated With Arthroscopic Repair Versus Open Latarjet

Background: Bony Bankart lesions can perpetuate chronic anterior glenohumeral instability. When surgical treatment is pursued, several factors need to be considered to obtain optimal outcomes. Purpose: To (1) quantitatively describe patterns of bone fragment resorption and associated risk factors for developing glenoid bone loss (GBL) and (2) to compare clinical and radiological results of attritional bone loss treated with either the arthroscopic Bankart or the open Latarjet procedure. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective analysis of prospectively collected data was conducted for patients who underwent arthroscopic stabilization (group A1, 10%-20% GBL; group A2, >20% GBL) or open Latarjet (group B, >10% GBL) for recurrent shoulder instability with bony Bankart lesion. Patient characteristics, number of dislocations, and Western Ontario Shoulder Instability Index (WOSI) scores were obtained. Pre- and postoperative computed tomography imaging was used to quantitatively describe patterns of bone fragment resorption. Results: A total of 120 consecutive patients (group A1, 40; group A2, 23; group B, 57) were included in the study, with a mean age of 25.6 years (range, 19-35 years). The average follow-up was 5.0 years for all groups (range, 4.83-5.16 years in group A1, 4.58-5.41 years in group A2, and 4.33-5.67 years in group B). The mean times between dislocation event and surgery were 12.8 months (range, 6-32 months) and 13.6 months (range, 6-38 months) for groups A and B, respectively. Redislocation rates were 7.5% in group A1 versus 13.0% in group A2, and only occurred in patients with ≥13.5% GBL. There were no redislocations for group B (0%). Patients had better WOSI scores in group B (234.1 ± 126.9) than in group A (576.1 ± 224.6) (P < .0001). In group A, smaller preoperative bone fragment size displayed a higher percentage of resorption after surgery (r = −0.64; P < .05). Conclusion: A significant inverse relationship exists between preoperative bone fragment size and percentage of postoperative resorption. Patients treated with arthroscopic bony Bankart repair who had final GBL ≥13.5% had worse outcomes. When planned GBL approaches 13.5% in high-demand patients, a smaller fragment size can result in worse clinical outcomes because of resorption. In these cases, choosing the open Latarjet procedure leads to better clinical results.
