Subjective Shoulder Value for Sport Is a Simple, Reliable, and Valid Score to Assess Shoulder Function in Athletes.

PURPOSE: To validate the subjective shoulder value for sport (SSV-Sport) by measuring its correlation with existing patient-reported outcome measures (PROMs) and defining its psychometric properties. METHODS: Between May 2021 and May 2022, we established 2 patient groups. Group 1 included those (1) aged 18 years or older, who were (2) consulting for the first time for any shoulder condition, (3) regularly participated in sports, and were capable of accessing a questionnaire independently. There were asked to rate their SSV and SSV-Sport at admission and 2 weeks later; they also were asked to answer a questionnaire including other PROMS. Group 2 comprised patients who had (1) undergone shoulder stabilization surgery and had (2) a minimum follow-up period of 6 months. RESULTS: For the shoulder disability patients (group 1, n = 62), there was a strong and significant correlation between SSV-Sport and other PROMs: Quick Disabilities of the Arm, Shoulder and Hand Sport (r = 0.84), Walch-Duplay (r = 0.65), Rowe (r = 0.74), Western Ontario Shoulder Instability (r = 0.78), and SSV (r = 0.75) (P = .0001). The SSV-Sport was reliable at baseline and 2 weeks after (0.91, 95% confidence interval 0.85-0.94), and was responsive to change (P < .001). For the anterior instability patients (group 2, n = 83), SSV was on average 50 points greater than SSV-Sport (29.2 vs 79.4, P < .001) for preoperative values. In both groups, the values of SSV were constantly and significantly higher than the values of SSV-Sport (81.9 ± 21.3 vs 54.8 ± 30.9; P < .001). CONCLUSIONS: The SSV-Sport is an easily administered, reliable, responsive, and valid measure of shoulder function in athletes that is highly correlated with other PROMs. SSV-Sport is better adapted than SSV to quantify pre- and postoperative shoulder deficiency in athletes. LEVEL OF EVIDENCE: Level III, cohort study (diagnosis).

Recurrent Anterior Shoulder Instability Treated Using the Arthroscopic Bankart-Latarjet Technique: Experience of a Peripheral Hospital.

The arthroscopic Bankart-Latarjet procedure is used in the surgical management of anterior shoulder instability. This technique is mainly performed in referral centers due to its high technicity. This study aimed to evaluate surgical outcomes in a peripheral hospital center. This is a retrospective study of patients treated for recurrent anterior shoulder instability. The clinical scores (Walch-Duplay, Rowe, and Western Ontario Shoulder Instability Index (WOSI)) were assessed preoperatively and at 12 months after surgery. The consolidation and the position of the bone block were evaluated at 6 months using a CT scan. Between 2016 and 2020, 40 patients had been operated on (mean age: 28.5 ± 7.9 years). During a mean follow-up of 29.5 ± 11.6 months, we noted only one complication, a case of fracture of the callus of a consolidated bone block. No recurrence of instability was recorded. The Walch-Duplay score increased from 17.8 to 94.6, the Rowe score from 24.9 to 96.8, and the WOSI score decreased from 52.1% to 6.9%. The bone block was consolidated in 35 patients (87.5%), and a flush position with the anterior edge of the glenoid was noted for all patients. At one year, 67.0% of the patients practicing sport had returned to sports. The arthroscopic Bankart-Latarjet technique was a reliable procedure in the hands of an experienced shoulder surgeon, even in a peripheral hospital center.

Bony increased-offset-reverse shoulder arthroplasty: 5 to 10 years' follow-up.

BACKGROUND: Glenoid lateralization has been shown to be the most imortant factor in maximizing passive range of motion and shoulder stability while preventing scapular impingement and notching. We aimed to evaluate mid- to long-term functional and radiologic outcomes after bony increased-offset-reverse shoulder arthroplasty (BIO-RSA) using a Grammont-style (medialized) humeral implant. METHODS: The study included 143 consecutive shoulders (140 patients; mean age, 72 years) treated with a BIO-RSA for rotator cuff deficiency. A cylinder of autologous cancellous bone graft, harvested from the humeral head, was placed between the reamed glenoid surface and baseplate; fixation was achieved using a long central peg (25 mm) and 4 screws. A large baseplate (29 mm) with a small baseplate sphere (36 mm) was used in 77% of cases, and a Grammont-style (medialized) humeral implant with 155° of inclination was used in all cases. All patients underwent clinical and radiographic assessment at a minimum of 5 years after surgery; in addition, 86 cases (60%) underwent computed tomography scan assessment. RESULTS: At a mean follow-up of 75 months (range, 60-126 months), the survivorship of the BIO-RSA using revision as an endpoint was 96%. No cases of dislocation or humeral loosening were observed. Overall, 118 patients (83%) were either very satisfied (61%) or satisfied (22%). The adjusted Constant score improved from 40% ± 18% to 93% ± 23%, and the Subjective Shoulder Value improved from 31% ± 15% to 77% ± 18% (P < .001). The humeral bone graft incorporated completely in 96% of cases (137 of 143). Severe inferior scapular notching (grade 3 or 4) occurred in 18% (24 of 136). The risk of postoperative notching correlated to a lower body mass index (P < .05), superior glenosphere inclination (P = .02), and high or flush glenosphere positioning (P = .035). CONCLUSIONS: BIO-RSA is a safe and effective technique to lateralize the glenoid, providing consistent bone graft healing, excellent functional outcomes, a low revision rate, and a high rate of patient satisfaction. Thin patients (with a low body mass index) and glenosphere malposition (with persistent superior inclination and/or insufficient lowering of the baseplate and sphere) are associated with higher risk of scapular notching.Our data confirm the importance of implanting the baseplate with a neutral inclination (reverse shoulder arthroplasty angle < 5°) and with sufficient glenosphere inferior overhang (>5 mm) in preventing scapular notching. The use of a less medialized humeral implant (135° or 145° inclined) and smaller (25-mm) baseplate (when using a small, 36-mm sphere) should allow reduction in the incidence of scapular notching.

Displaced humeral surgical neck fractures: classification and results of third-generation percutaneous intramedullary nailing.

BACKGROUND: The high rates of complications and reoperations observed with the early designs of first-generation (unlocked) and second-generation (bent design) humeral intramedullary nail (IMNs) have discouraged their use by most surgeons. The purpose of this study was to report the results of a third-generation (straight, locking, low-profile, tuberosity-based fixation) IMN, inserted through a percutaneous approach, for the treatment of displaced 2-part surgical neck fractures. METHODS: We performed a retrospective review of 41 patients who underwent placement of a third-generation IMN to treat a displaced 2-part surgical neck fracture (AO/OTA type 11A3). The mean age at surgery was 57 years (range, 17-84 years). After percutaneous insertion through the humeral head, the IMN was used as a reduction tool. Static locking fixation was achieved after axial fracture compression ("back-slap" hammering technique). Patients were reviewed and underwent radiography with a minimum of 1 year of follow-up; the mean follow-up period was 26 months (range, 12-53 months). RESULTS: Preoperatively, 3 types of surgical neck fractures were observed: with valgus head deformity (Type A = 8 cases), shaft translation without head deformity (Type B = 19 cases), or with varus head deformity (Type C = 14 cases). At final follow-up, all fractures went on to union, and the mean humeral neck-shaft angle was 132° ± 5°. We observed 2 malunions and 1 case of partial humeral head avascular necrosis. No cases underwent screw migration or intra-articular penetration. At last review, mean active forward elevation was 146° (range, 90°-180°) and mean external rotation was 50° (range, 20°-80°). The mean Constant-Murley score and Subjective Shoulder Value were 71 (range, 43-95) and 80% (range, 50%-100%), respectively. CONCLUSIONS: Antegrade insertion of a third-generation IMN through a percutaneous approach provides a high rate of fracture healing, excellent clinical outcome scores, and a low rate of complications. No morbidity related to the passage of the nail through the supraspinatus muscle and the cartilage was observed. The proposed A, B, and C classification allows choosing the optimal entry point for intramedullary nailing.

Percutaneous Medial Ligament Reconstruction for Valgus and Rotational Knee Instability.

The following surgical technique is intended for patients with chronic valgus laxity and rotational knee instability. It is a percutaneous 2-bundle ligament reconstruction method that uses the semitendinosus tendon, allowing it to remain pedicled to its distal tibial insertion. The aim is to correct the laxity without otherwise limiting the motion of the knee.

Percutaneous Medial Ligament Reconstruction for Valgus Knee Instability.

Injuries to stabilizing elements on the medial side of the knee are one of the most common knee ailments. Because of the good healing capacity of these structures, acute injuries are typically treated conservatively. However, valgus laxity near full extension can persist in some patients. This laxity may be the source of instability due to medial joint space opening, which then requires surgical treatment. Various procedures have been described that aim to reproduce the anatomy of the medial collateral ligament (MCL) and the posterior oblique ligament (POL), which work together to stabilize the medial aspect of the knee. However, these are complex open surgical procedures, technically demanding to achieve the favorable isometry, which prevent joint contracture or recurrence of laxity. The purpose of this study was to describe a short construct that minimizes the risk of secondary loss of tension and complies with the principle of favorable anisometry. The graft is positioned in the joint opening axis, between the deep bundle of the MCL and the POL.

The open latarjet procedure is more reliable in terms of shoulder stability than arthroscopic bankart repair.

BACKGROUND: Arthroscopic Bankart repair and open Latarjet bone block procedure are widely considered mainstays for surgical treatment of recurrent anterior shoulder instability. The choice between these procedures depends mainly on surgeon preference or training rather than published evidence. QUESTIONS/PURPOSES: We compared patients with recurrent posttraumatic anterior shoulder instability treated with arthroscopic Bankart or open Latarjet procedure in terms of (1) frequency and timing of recurrent instability, (2) risk factors for recurrent instability, and (3) patient-reported outcomes. METHODS: In this retrospective comparative study, we paired 93 patients undergoing open Latarjet procedures with 93 patients undergoing arthroscopic Bankart repairs over the same period for posttraumatic anterior shoulder instability by one of four surgeons at the same center. Both groups were comparable except that patients in the Latarjet group had more glenoid lesions and more instability episodes preoperatively. Minimum followup was 4 years (mean, 6 years; range, 4-10 years). Patients were assessed with a questionnaire, including stability, Rowe score, and return to sports. Recurrent instability was defined as at least one episode of recurrent dislocation or subluxation. Return to sports was evaluated using a 0% to 100% scale that patients completed after recovery from surgery. Various risk factors for recurrent instability were also analyzed. RESULTS: At latest followup, 10% (nine of 93) in the Latarjet group and 22% (20 of 93) in the Bankart group demonstrated recurrent instability (p = 0.026; odds ratio, 0.39; 95% CI, 0.17-0.91). Ten recurrences in the Bankart group (50%) occurred after 2 years, compared to only one (11%) in the Latarjet group. Reoperation rate was 6% and 7% in the Bankart and Latarjet groups, respectively. In both groups, patients younger than 20 years had higher recurrence risk (p = 0.019). In the Bankart group, independent factors predictive for recurrence were practice of competitive sports and shoulder hyperlaxity (ie, passive external rotation > 85° in the contralateral uninjured shoulder). Although return to sports was not different between groups, the mean Rowe score was higher in the Latarjet group (78 versus 68, p = 0.018). CONCLUSIONS: Patients who had the open Latarjet procedure had less recurrent instability and better Rowe scores over a mean 6-year followup. We now perform isolated arthroscopic Bankart repair for carefully selected patients, including patients with an Instability Severity Index Score of 3 or less.
