Arthroscopic Bankart Repair With Remplissage in Anterior Shoulder Instability Results in Fewer Redislocations Than Bankart Repair Alone at Medium-term Follow-up of a Randomized Controlled Trial

Background: A multicenter, double-blinded randomized controlled trial comparing isolated Bankart repair (NO REMP) to Bankart repair with remplissage (REMP) reported benefits of remplissage in reducing recurrent instability at 2 years postoperative. The ongoing benefits beyond this time point are yet to be explored. Purpose: To (1) compare medium-term (3 to 9 years) outcomes of these previously randomized patients undergoing isolated Bankart repair (NO REMP) or Bankart repair with remplissage (REMP) to manage recurrent anterior glenohumeral instability; (2) examine the failure rate, overall recurrent instability, and reoperation rate. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Recruitment and randomization for the original randomized trial occurred between 2011 and 2017. Patients ≥14 years diagnosed with recurrent traumatic anterior shoulder instability with an engaging Hill-Sachs defect of any size were included. Those with a glenoid defect >15% were excluded. In 2020, participants were contacted by telephone and asked standardized questions regarding ensuing instances of subluxation, dislocation, or reoperation on their study shoulder. “Failure” was defined as a redislocation, and “overall recurrent instability” was described as a redislocation or ≥2 subluxations. Descriptive statistics, relative risk, and Kaplan-Meier survival curve analyses were performed. Results: A total of 108 participants were randomized, of whom 50 in the NO REMP group and 52 in the REMP group were included in the analyses in the original study. The mean number of months from surgery to the final follow-up was 49.3 and 53.8 months for the NO REMP and REMP groups, respectively. Failure rates were 22% (11/50) in the NO REMP group versus 8% (4/52) in the REMP group. Rates of overall recurrent instability were 30% (15/50) in the NO REMP group versus 10% (5/52) in the REMP group. Survival curves were significantly different, favoring REMP in both scenarios. Conclusion: For the treatment of traumatic recurrent anterior shoulder instability with a Hill-Sachs lesion and subcritical glenoid bone loss (<15%), a significantly lower rate of overall postoperative recurrent instability was observed with arthroscopic Bankart repair and remplissage than with isolated Bankart repair at a medium-term follow-up (mean of 4 years). Patients who did not receive a remplissage experienced a failure (redislocated) earlier and had a higher rate of revision/reoperation than those who received a concomitant remplissage.

Functional Outcome of Arthroscopic Bankart Repair with Knotless Suture Anchor: A Retrospective Observational Study

Background: The soft tissue in the shoulder plays a significant role in anterior shoulder instability, leading to humeral head displacement from the glenoid fossa. Arthroscopic Bankart repair is a widely accepted method to restore the labrum to the joint rim. This study aims to evaluate the clinical outcomes of Bankart repair by knotless suture anchors at medium-term follow-up, assess the functional outcomes of the knotless suture anchor method for recurrent anterior glenohumeral instability, and conduct clinical assessment using the Rowe score at 6-week, 3-month, 6-month, and 12-month intervals in patients. Methods: In this retrospective study, patients who underwent arthroscopic Bankart repair using a 2.8 mm knotless suture anchor (MINI-VIM PK® ) were enrolled. They were assessed for shoulder stability, range of motion (ROM), and functional outcomes using the Rowe scale at the baseline, 6-week, 3-month, 6-month, and 12-month follow-up intervals as part of the planned early efficacy measures. All the statistical analyses were performed using SPSS software. Results: The mean age of the subjects was 28.10 ± 6.14. In this trial, 51 patients (69.86%) were diagnosed with recurrent shoulder dislocation on the left side, and 22 patients (30.14%) on the right side. The Rowe score demonstrated a significant improvement (P &lt; 0.0001), increasing from 44.73 ± 1.64 to 95.62 ± 18.33 at the 12-month follow-up period. This indicated better clinical outcomes and reduced recurrence of instability with the use of knotless suture anchors. Conclusion: The use of knotless suture anchors demonstrated reduced recurrence rates, improved post-operative shoulder motion, and increased stability without adding complexity to the procedure.

Arthroscopic Bankart repair with peeling osteotomy of the anterior glenoid rim preserves glenoid morphology.

A decrease in the glenoid size after arthroscopic Bankart repair (ABR) was common in shoulders without osseous fragments compared with those with osseous fragments. For cases of chronic recurrent traumatic anterior glenohumeral instability without osseous fragments, we have performed ABR with peeling osteotomy of the anterior glenoid rim (ABRPO) to make an intentional osseous Bankart lesion. The aim of this study was to compare the glenoid morphology after ABRPO with it after simple ABR. The medical records of patients who underwent arthroscopic stabilization for chronic recurrent traumatic anterior glenohumeral instability were retrospectively reviewed. Patients with an osseous fragment, with revision surgery and without complete data were excluded. Patients were assigned to 1 of 2 groups: Group A, ABR without peeling osteotomy procedure or Group B, with ABRPO procedure. Computed tomography was performed preoperatively and 1year after surgery. The size of the glenoid bone loss was investigated by the assumed circle method. The following formula was used to calculate the decreased size of the glenoid: (Δ) = (postoperative size of the glenoid bone loss) - (preoperative size of the glenoid bone loss). The size of the glenoid 1year after surgery was assessed to determine if it had decreased (Δ>0%) or not decreased (Δ≤0%) relative to the preoperative size. This study evaluated 39 shoulders divided into 2 groups: 27 shoulders in Group A and 12 shoulders in Group B. In Group A, postoperative glenoid bone loss was significantly greater than preoperative glenoid bone loss (7.8±6.2 vs. 5.5±5.3, respectively, P=.02). In Group B, postoperative glenoid bone loss was significantly lower than preoperative glenoid bone loss (5.6±5.4 vs. 8.7±4.0, respectively, P=.02). The P value for the interaction of group (A or B) × time (preoperative or postoperative) was 0.001. The decreased size of the glenoid was significantly larger in Group A than in Group B (2.1±4.2 vs. -3.1±4.5, respectively, P=.001). The rate of shoulders in which the size of the glenoid decreased 1year after surgery relative to the preoperative size was significantly higher in Group A than in Group B (63% [17/27] vs. 25% [3/2], respectively, P=.04). The study showed that ABRPO preserved the glenoid size better than simple ABR without a peeling osteotomy procedure.

Utility of Talus Osteochondral Allograft Augmentation for Varying Hill-Sachs Lesion Sizes: A Cadaveric Study.

Humeral head reconstruction with fresh osteochondral allografts (OCA) serves as a potential treatment option for anatomic reconstruction. More specifically, talus OCA is a promising graft source because of its high congruency with a dense cartilaginous surface. To analyze the surface geometry of the talus OCA plug augmentation for the management of shoulder instability with varying sizes of Hill-Sachs lesions (HSLs). Controlled laboratory study. Seven fresh-frozen cadaveric shoulders were tested in this study. The humeral heads were analyzed using actual patients' computed tomography scans. Surface laser scan analysis was performed on 7 testing states: (1) native state; (2) small HSL; (3) talus OCA augmentation for small HSL; (4) medium HSL; (5) talus OCA augmentation for medium HSL; (6) large HSL; and (7) talus OCA augmentation for large HSL. OCA plugs were harvested from the talus allograft and placed in the most medial and superior aspect of each HSL lesion. Surface congruency was calculated as the mean absolute error and the root mean squared error in the distance. A 1-way repeated-measures analysis of variance was performed to evaluate the effects of the difference in the HSL size and associated talus OCA plugs on surface congruency and the HSL surface area. The surface area analysis of the humeral head with the large (1469 ± 75 mm2), medium (1391 ± 81 mm2), and small (1230 ± 54 mm2) HSLs exhibited significantly higher surface areas than the native state (1007 ± 88 mm2; P < .001 for all sizes). The native state exhibited significantly lower surface areas as compared with after talus OCA augmentation for large HSLs (1235 ± 63 mm2; P < .001) but not for small or medium HSLs. Talus OCA augmentation yielded improved surface areas and congruency after treatment in small, medium, and large HSLs (P < .001). Talus OCA plug augmentation restored surface area and congruency across all tested HSLs, and the surface area was best improved with the most common HSLs-small and medium. Talus OCA plugs may provide a viable option for restoring congruity of the shoulder in patients with recurrent anterior glenohumeral instability and an HSL.

Recurrent Instability After Arthroscopic Bankart Repair in Patients With Hyperlaxity and Near-Track Lesions.

Recurrent anterior shoulder instability after arthroscopic Bankart repair presents a challenging clinical problem, with the primary stabilization procedure often portending the best chance for clinical success. To determine if capsuloligamentous laxity affects failure (recurrent dislocation, subluxation, and/or perceived instability symptoms) after arthroscopic Bankart repair in patients with near-track lesions (ie, those with smaller distance to dislocation [DTD]). Case-control study; Level of evidence, 3. The authors retrospectively reviewed consecutive patients who underwent primary arthroscopic Bankart repair for recurrent anterior glenohumeral instability at a single institution between 2007 and 2019 and who had at least 2 years of follow-up data. Patients with glenoid bone loss >20%, off-track lesions, concomitant remplissage, or rotator cuff tear were excluded. Capsuloligamentous laxity, or hyperlaxity, was defined as external rotation >85° with the arm at the side and/or grade ≥2 in at least 2 planes with the shoulder at 90° of abduction. Near-track lesions were defined as those with a DTD <10 mm. Included were 173 patients (mean age, 20.5 years; mean DTD, 16.2 mm), of whom 16.8% sustained a recurrent dislocation and 6.4% had recurrent subluxations (defined as any subjective complaint of recurrent instability without frank dislocation), for an overall recurrent instability rate of 23.1%. The rate of revision stabilization was 15.6%. The mean time to follow-up was 7.4 years. Independent predictors of recurrent instability were younger age (P = .001), smaller DTD (P = .021), >1 preoperative instability episode (P < .001), and the presence of hyperlaxity during examination under anesthesia (P = .013). Among patients with near-track lesions, those with hyperlaxity had a recurrent instability rate almost double that of patients without hyperlaxity (odds ratio, 34.1; P = .04). The increased rate of failure and recurrent dislocation in the near-track hyperlaxity cohort remained elevated, even in patients with no bone loss. Capsuloligamentous shoulder laxity was a significant independent risk factor for failure after primary arthroscopic Bankart repair without remplissage and was more predictive of failure in patients with versus without near-track lesions.

Surgical Technique for the Latarjet Procedure Using Non-Cannulated Screws

Background: The Latarjet procedure is effective for patients with anterior glenohumeral instability with substantial glenoid bone loss due to its triple blocking effect. Indications: Indications include high-risk patients with recurrent anterior glenohumeral instability with any glenoid bone loss or low-risk patients with 15% to 30% glenoid bone loss. Technique Description: An incision is made lateral to the coracoid and the deltopectoral interval is established. The pectoralis minor is released medially off the coracoid and the coracoacromial (CA) ligament is released close to the acromion. The coracoid is cut with a right-angle saw and the inferior coracoid is decorticated with a burr. Two holes are pre-drilled in the coracoid. The subscapularis is split between the upper two-thirds and lower one-third with the arm in external rotation. The capsule is split vertically at the joint line and the humeral head is retracted. The anterior glenoid is decorticated with a burr, and a hole is drilled inferiorly. The depth is measured and added to the depth of the inferior bone block hole. A fully threaded 3.5-mm solid stainless steel screw is placed in the inferior hole. Care is taken to ensure that the lateral border of the bone block is flush with the articular margin. This is repeated for the superior hole. A 1.8-mm knotless suture anchor is placed between the screws. The repair stitch is passed through the capsule and loaded onto the anchor and tensioned. The CA ligament is laid over the capsule and repaired. The subscapularis split is repaired side to side and the wound is closed in layers. Results: High return-to-sport rates, including at the same level of play, have been observed among young competitive athletes with significant glenoid bone loss who underwent a Latarjet, with similarly favorable results in older patients. Ninety-day complication rates have been reported around 9%, 5% of which constituted graft or hardware failures. Discussion/Conclusion: The Latarjet procedure is an effective option for indicated patients with anterior glenohumeral instability and may be enhanced with solid screws, proper anatomic technique, and capsulolabral repair augmentation.

Evaluation of Kinesiophobia in Patients Treated with Arthroscopic Bankart Repair for Recurrent Anterior Glenohumeral Instability

Evaluation of Kinesiophobia in Patients Treated with Arthroscopic Bankart Repair for Recurrent Anterior Glenohumeral Instability

Paper 01: Capsuloligamentous Laxity is a Risk Factor for Failure in Near Track Lesions Following Arthroscopic Anterior Shoulder Stabilization

Objectives: Recurrent anterior shoulder instability after arthroscopic Bankart repair presents a challenging clinical problem, with the primary stabilization procedure often portending the best chance for clinical success. While the glenoid track concept continues to evolve, a limitation of the glenoid track is that it relies on bony anatomy without specific considerations for capsuloligamentous integrity or the effect that capsular laxity may have on the glenohumeral contact points throughout shoulder range of motion. The purpose of the study was to determine if capsuloligamentous laxity has a modifying effect on the glenoid track, specifically for on-track lesions with a small distance to dislocation (DTD) from being an off-track lesion or the so-called “near-track” lesion. This may explain why some on-track lesions are at an increased risk of recurrent instability. We hypothesized that patients with ligamentous laxity and “near track” lesions would be at increased risk of recurrent instability following arthroscopic Bankart repair. Methods: Consecutive patients with on-track Hill-Sachs lesions who underwent primary arthroscopic Bankart repair alone without remplissage for recurrent anterior glenohumeral instability between January 2007 and December 2015 at a single institution were retrospectively reviewed. Patients with less than 2-year follow up, glenoid bone loss &gt; 20%, off-track lesions, concomitant remplissage, and atraumatic instability were excluded. Determination of shoulder laxity was based on exam under anesthesia (EUA), including anterior load and shift, posterior load and shift, and sulcus testing at the time of surgery before arthroscopy. Capsuloligamentous shoulder hyperlaxity was defined as external rotation of &gt;85o and/or grade of 2+ or greater load and shift in two or more planes. Measurements of glenoid bone loss, Hill-Sachs interval (HSI), and glenoid track (GT) were performed based on prior described methods. DTD was calculated (DTD=GT-HSI, with DTD&gt;0 classified as on-track lesions). Near track lesions were defined as 0&lt;DTD&lt;8mm. Failure was defined as recurrent dislocation. Results: A total of 173 patients were initially identified, of which 151 met inclusion criteria and were included for analysis. 72.8% of patients were males and mean age was 20.1 ± 5.7 years. Patients were divided into two groups based on shoulder laxity; group 1 consisted of 74 patients with hyperlaxity, and group 2 consisted of 77 patients without hyperlaxity. Overall, 21 patients (13.9%) sustained a recurrent dislocation and 35 patients (23.2%) had recurrent instability episodes. Failure was associated with glenoid bone loss (p&lt;0.001 ), longer HS length ( p=0.007), occurrence of &gt;1 instability episode preoperatively (p=0.018 ), and smaller DTD ( p=0.0008). Hyperlaxity was associated with the use of more anchors ( p=0.0001). Shoulder laxity was not independently predictive of overall failure (Figure 1, p=0.18); however, DTD was significantly associated with failure risk and recurrent instability in patients with hyperlaxity ( p=0.006) specifically in younger patients with hyperlaxity (Figure 1, Table 1). Conclusions: Our study suggests that while capsuloligamentous laxity is not independently predictive of failure after arthroscopic Bankart repair for on-track lesions, laxity may play a significant role in clinical outcomes in patients with a small DTD or near-track lesions. In younger patients with near-track lesions, hyperlaxity may be particularly predictive of failure after arthroscopic Bankart repair. As our understanding of the glenoid track continues to evolve, surgeons may need to consider the track concept as a continuum with evolving surgical algorithms other than an arthroscopic Bankart alone in young patients with near track lesions and hyperlaxity.

Recurrent anterior Gleno-humeral instability: A review of latarjet procedure and its complications

The shoulder is the most mobile joint whose stability requires the interaction of both dynamic and static stabilizers. Its wide range of movement predisposes to a high susceptibility to dislocation accounting for nearly 50% of all dislocations. This trauma typically results in ligament injury (e.g., labral tear, capsular strain) or bony fracture (e.g., loss of glenoid or humeral head bone), which frequently causes recurrent instability. Patients with significant glenoid defect may require Latarjet procedure which involves transferring the coracoid to the antero-inferior glenoid rim. In spite of outstanding results, 15 to 30% of cases suffer complications. In this article, we discuss the diagnosis of recurrent shoulder instability, the surgical technique and various complications of Latarjet procedure.

Functional results and return to sports on recurrent anterior glenohumeral instability. Influence of the COVID-19 pandemic; Comparative retrospective study and short-term results.

Our objective is to compare the functional results in patients that underwent surgery for recurrent anterior shoulder instability (RAGHI) during the COVID-19 pandemic with remotely-based rehabilitation, to those who had surgery before the pandemic and had in-person rehabilitation therapy. A retrospective case series of 68 patients were included and divided into two groups: In person-group and Home-based group. Western Ontario Shoulder Instability Index (WOSI) and Subjective Shoulder Value (SSV) scores were used to evaluate objective and subjective clinical parameters. Time and level of return to sports was studied by the Subjective Patient Outcome for Return to Sports (SPORTS) score. The mean SSV score was 82% (40-100) on the In-Person group compared with 87% (65-100) for the Home-Based group. Results for WOSI score were similar, with an average of 210.42 (90%) for In-Person and 261.45 (88%) for the Home-Based group (p 0.12). Return to sports was carried out in an average of 6.6 (4-16)months for In-Person group, compared to 6.5 (5-8)months for Home-Based. Follow-up and rehabilitation methods for patients who underwent surgery for RAGHI, during COVID-19 lockdown, were not significantly (p 0.12) affected on functional and athletic return in comparison to traditional methods according to WOSI scale. IV Retrospective series of cases.

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.

Quality of life following an open Latarjet-Bristow procedure in a general population with recurrent anterior shoulder instability

Despite the extensive literature on anterior glenohumeral instability, to date, there are no studies that report on the quality of life following a Latarjet-Bristow procedure with recurrent anterior shoulder instability. The purpose of this study was to evaluate the quality of life in patients who had a Latarjet-Bristow procedure. A single-center retrospective review with a prospective recall of patients who underwent a Latarjet-Bristow technique for recurrent anterior glenohumeral instability between January 2017 and March 2020. Outcomes measures included health-related quality of life using the Short Form-36 (SF-36) questionnaire and patient-related outcome measures using the Western Ontario Shoulder Instability Index and Rowe scores. A total of 66 patients were identified to participate in the study; 40 (60.6%) responded and were included in the analysis. There were nine females and 31 males, with a median age of 32 years (27.5‒41 years). Three cases had bilateral anterior shoulder instability with a single joint being operated and three patients were epileptic. Physical and mental components summary of the SF-36 showed a better health-related quality of life in the general population. There was a significant strong correlation between SF-36 and Western Ontario Shoulder Instability Index. However, SF-36 and Rowe score showed a fair correlation. The Latarjet-Bristow procedure improves the quality of life in a general population similarly to an athletic population. The number of episodes of dislocation before surgery and the delayed surgical intervention did not increase the recurrent anterior shoulder instability rates postoperatively.

Clinical outcomes following open anterior shoulder stabilization for glenohumeral instability in the young collision athlete.

Anterior glenohumeral instability occurs most commonly in those aged 15-29, with 72% of individuals younger than 22 years suffering recurrent episodes; collision athletes are at particular risk. In the setting of subcritical glenoid bone loss, arthroscopic Bankart repair is widely used despite concerns of recurrent dislocations when compared with open techniques. Furthermore, indications for bone-block procedures are evolving with the Latarjet procedure being favored amongst recent authors as a primary stabilization method in elite and contact athletes. To determine the efficacy of open modified Bankart stabilization in treating anterior glenohumeral instability in young collision athletes. This was a retrospective review of outcomes of consecutive patients aged 15-20 years who underwent unilateral or bilateral open stabilization for recurrent anterior glenohumeral instability over a 7-year period (2007-2015). The cohort was selected as recent literature suggests that this is the group with the highest redislocation rate and poorest outcomes. Outcome assessments included redislocation rate, return to sport, pain score, patient-related satisfaction scores, and the Western Ontario Shoulder Instability Index. A total of 60 patients (55 male: 5 female) of mean age 18 years (range: 15-20 years) were available for follow-up at 7 years. All but 3 were competitive athletes with 18 competing regionally and 9 internationally; rugby union and rugby league represent the most common sports. Fifty-five of 60 (92%) have returned to their desired level of sport with 62% of athletes returning to their previous level of competition sport and 1 retuning at a higher level. The mean postoperative pain score was 2.5/10. The mean time to return to play was 14 months (range: 5-48 months). Eight of 60 shoulders reported redislocation (13%), 7 of these being traumatic dislocations after return to high-impact sporting activities. At 7 years of follow-up, 4 of 60 shoulders (7%) had undergone revision surgery. Young collision athletes represent a challenging cohort of instability patients. This study of open modified Bankart in young collision sport athletes revealed excellent outcomes with 92% return to sport and a low revision rate. The results from this cohort rival those of arthroscopic repair. The open procedure described here in this 7-year series represents a robust, reliable technique that could be considered as an alternative to arthroscopic Bankart due to concern for recurrence, while avoiding potential morbidity and complication of bone-block procedures. There is still a role for the open modified Bankart procedure in treating traumatic anterior instability.

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.

Arthroscopic Latarjet for Primary Shoulder Instability With Off-Track Lesions or Revision Surgery Yields Satisfactory Clinical Results and Reliable Return to Sport and Work at Minimum 3-Year Follow-Up

To retrospectively evaluate clinical and radiologic outcomes and return to sport and to work of patients after arthroscopic Latarjet stabilization for primary instability or revision surgery; factors influencing and determining results and potential predictors for clinical outcomes also were evaluated. This is a retrospective study including patients older than 18 years old who underwent arthroscopic Latarjet stabilization for recurrent anterior glenohumeral instability with off-track lesions, or for cases of recurrence after previous surgery, from 2011 to 2017. Patients were assessed preoperatively and at a minimum 3 years of follow-up using the Rowe score, the University of California at Los Angeles Shoulder Score and Simple Shoulder Test score; the range of motion, satisfaction rate, return to work and sport, perception of discomfort during sporting and daily activities, and complications and recurrence after surgery were also evaluated. The integration of the coracoid graft and the position of the screws were examined by computed tomography scan. At a mean follow-up time of 6 ± 2 years, 93 patients (95 shoulders) showed significant improvement of all scale scores (P < .001), 97.8% of the patients had returned to the same working condition as before surgery, and all the patients who practiced sports preoperatively (85; 91.4%) returned to sport after surgery; 97.9% of patients were satisfied with surgery. The complication rate was 5.4%, and 2 cases (2.1%) of recurrence occurred, both after high-energy trauma. At an average of 17 ± 13 months postoperatively, computed tomography scans showed 4 (6.6%) stable nonunions, 9 (14.8%) superior, and 1 (1.6%) inferior lyses of the graft; a correct positioning of the graft was observed in 86.9% of the cases. Greater satisfaction, fewer complications, less pain during daily activities, and a lower number of reoperations were associated with a shorter time between the first dislocation episode and surgery (P= .019, P < .001, P= .014, and P=.005, respectively). Complications were directly associated with older patient age at operation (P= .001). A greater number of nonunions was found in patients with increased angle between the line linking the posterior and anterior glenoid rim and the screw axis (P= .040) and a medial axial position or a lower coronal position of the graft (both P=.010). A lower age at the time of surgery predicted better Rowe scores at follow-up (P < .001), and a lower age at the time of the first episode of dislocation predicted better postoperative Simple Shoulder Test scores (P= .026). At a mean 6-year follow-up time, excellent clinical outcomes, and radiological results, with few complications, high rates of satisfaction and return to work and sport and low sports anxiety can be expected after arthroscopic Latarjet procedure. A shorter time between the first dislocation episode and surgery was associated with higher satisfaction, fewer complications, less pain during daily activities and lower reoperations; a lower age at the operation was associated with lower complications.

Outcomes of Arthroscopic Latarjet Procedure for Anterior Glenohumeral Instability in Patients With Epilepsy: A Case-Control Study

Background: Unacceptably high rates of redislocation, reoperation, osteoarthritis, and coracoid nonunion have been reported in patients with a seizure disorder after surgery for shoulder instabilitiy. Purpose: To evaluate the objective and subjective functional and radiologic results of the arthroscopic Latarjet procedure for anterior shoulder instability in patients with epilepsy and compare them with the results of patients without epilepsy. Study design: Cohort study; Level of evidence, 3. Methods: A retrospective and comparative case-control analysis of patients operated for shoulder instability with arthroscopic Latarjet was conducted. Nineteen patients (21 unstable shoulders) with a seizure disorder (epilepsy group) were matched with 21 patients without a history of seizure (control group). Demographics, surgical indications, and imaging data were collected. Clinical outcomes at a minimum 2 years of follow-up (range, 2-9 years) postoperatively included Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE). The incidence of complications, recurrent instability, redislocation, revision surgery, repeated seizure(s), and presence of osteoarthritis, coracoid nonunion, and osteolysis were also examined. Results: After a mean follow-up of 4.5 years, no significant differences in functional results were found between patients with and without epilepsy on the average Rowe (P = .917), WOSI (P = .621), CMSO (P = .600), and SANE (P = .859) scores. A total of 5 patients (7 shoulders) continued to have seizures postoperatively, but no seizure-related glenohumeral instability was documented. One dislocation and 1 subluxation were documented while participating in sports in each study group, comprising a recurrence rate of 9.5%, but no significant differences were found at comparison (P = .605). A bone defect did not influence the results, as no significant difference was found between the 2 groups. Osteoarthritic changes of the glenohumeral joint were observed in 5 shoulders (23.8%) in the epilepsy group and in 3 (14.3%) in the control group (P = .451). No case of coracoid nonunion or osteolysis was recorded. There was no statistically significant difference in postoperative athletic activity (P = .660). However, patients with epilepsy had significantly lower pre- and postoperative sports participation (P < .001). Conclusion: Arthroscopic Latarjet stabilization can lead to improved functional and subjective outcomes and should be considered in patients with epilepsy with recurrent anterior glenohumeral instability. These results can be achieved regardless of the presence of bone defect and the postoperative control of seizures and are similar to those in patients without epilepsy.

Arthroscopic “Double-Inlay” Eden-Hybinette Procedure with Modified Suture Button Fixation for the Revision of Failed Bristow-Latarjet

Bristow-Latarjet procedure has been widely regarded as a reliable and satisfactory operation for recurrent anterior glenohumeral instability, especially for patients with significant glenoid bone loss or high sports demand. Once failed, however, the subsequent revision surgery could be challenging. Eden-Hybinette procedure is the most common operation for revision of failed Bristow-Latarjet. It can perfectly restore the bone defect of the failed Bristow-Latarjet by harvesting a proper size of iliac bone block. Furthermore, several studies have shown the advantages of using suture button fixation in the revision surgery for failed Bristow-Latarjet procedure. However, the potential inferior biomechanical strength of suture button fixation is still a concern. This Technical Note introduced an arthroscopic “double-inlay” Eden-Hybinette procedure with modified suture button fixation for the revision of failed Bristow-Latarjet. With its “quadruple” reinforcement effect, this procedure can achieve an excellent biomechanical strength of fixation.

Le Bankart arthroscopique dans l’instabilité antérieure de l’épaule – étude rétrospective à 5 ans

BackgroundThis retrospective study investigated 5-year results of primary arthroscopic operation for anterior glenohumeral instability (AI) with special interest in patients aged <25 years and gender. HypothesisRecurrence of AI is higher in male patients aged <25 years than older patients or females. Patients and methodsPrimary arthroscopic Bankart repair was performed between January 2009 and December 2015 on 156 shoulders [154 patients, 104/156 (67%) males]. The mean follow-up was 5.6 (SD 2.1, range 0.4–8.9) years. Outcome measures, including re-dislocation, fear of dislocation, Western Ontario Instability Index, Subjective Shoulder Value and pain Numerical Rating Scale scores, the number of revision surgeries and satisfaction with the result of surgical treatment, were assessed for 130 shoulders [82/130 (63%) males]. AI recurrence was defined as a dislocation or a fear of such. ResultsThe Kaplan-Meier analysis estimates for the cumulative survival of stable shoulders were 28% at 8.8 years for patients aged <25 years (SE 0.4, CI 95% 5.5–7.2) and 53% at 8.9 years for patients aged ≥25years (SE 0.2, CI 95% 7.2–8.0; p=0.005). The Kaplan-Meier estimates for the cumulative survival of stable shoulders were 50% at 8.9 years for males (SE 0.3, CI 95% 6.8–7.8) and 37% at 8.6 years for females (SE 0.3, CI 95% 6.5–7.7; p=0.8). Mean time to revision was 2.4 (SD 1.7, range 0.4–5.3) years. DiscussionRecurrence of AI was higher in the patients aged <25 years (p=0.005) but gender was not a risk factor. Re-operation rate due to recurrent AI was 10% in this 5-year follow-up. Level of evidenceIII; Case-control study.

Arthroscopic Assisted Glenoid Reconstruction for Recurrent Anterior Glenohumeral Instability combined with Glenoid insufficiency

Background: Anterior recurrent glenohumeral instability is a common clinical entity, particularly among young athletic patient population with glenoid defect greater than 20%. Glenoid reconstruction with bone graft has become the treatment of choice.Aim of the work: evaluate the role of arthroscopic assisted reconstruction in management of recurrent anterior glenohumeral instability associated with glenoid insufficiency.Patients and Methods: Our prospective study was conducted involving 30 cases with anterior shoulder instability associated with glenoid defect more than 20%. All patients were operated at Zagazig University Hospitals. All cases were surgically managed by arthroscopic assisted reconstruction the glenoid defect by bone graft. 15 cases with coracoid process and 15 cases with tricortical iliac crest graft.Results: 30 patients were followed up for 12 monthes. All patients showed significant improving in the range of motions. No dislocation or subluxation recorded in any patients. All graft complete bony union except one showed fibrous union. UCLA and Consatnt score highly significant improved postoperative. Conclusion: Soft-tissue stabilization procedures for the treatment of anterior shoulder instability were proved to be less effective with high recurrence rate up to 67% in patients with extensive glenoid bone loss >20 %. So, bone grafting techniques instead of soft tissue stabilization procedures in the case of extensive glenoid bone loss > 20 %.
