Glenoid bone grafting with a reverse design prosthesis.

The purpose of this study was to evaluate the outcome of patients who underwent glenoid bone grafting and implantation of a reverse design prosthesis in 1 or 2 stages for the treatment of glenoid bone loss and rotator cuff insufficiency. Indications for the reverse prosthesis in this series included cuff tear arthropathy and revision arthroplasty. Nine patients were reviewed clinically and radiographically with a minimum 2-year follow-up (range, 24-41 months). Despite a low postoperative functional score (mean Constant score, 53 points [range, 22-79 points]), most patients were satisfied with their results primarily because of pain relief. (The mean pain score increased from 3 points preoperatively to 12.5 points postoperatively.) Radiographic evaluation did not demonstrate component loosening or evidence of graft failure. Six patients had radiographic evidence of an inferior scapular notch, which may be of concern in the future. Early results of this procedure are encouraging, but further clinical and radiologic assessment is necessary.

Arthroscopic debridement in the treatment of patients with isolated tears of the subscapularis.

PURPOSE: To evaluate the treatment of properly selected patients with isolated subscapularis tears by arthroscopic debridement and release of the long head of the biceps. METHODS: Eleven shoulders that had undergone arthroscopic debridement in the treatment of subscapularis tears were reviewed. In all patients, 3 months of appropriate nonoperative management had been unsuccessful. Patients were selected for arthroscopic debridement if the tear was thought to be irreparable, or if the patient was older and unwilling to participate in the rehabilitation required after repair had been completed. Mean age at surgery was 64 years. The mean time interval from onset of symptoms to surgery was 11 months. Seven tears were traumatic, and 4 were degenerative. Four tears involved the superior third of the subscapularis tendon, 2 involved the superior two thirds of the subscapularis tendon, and 5 were complete tears. Nine shoulders also had dislocation or subluxation of the long head of the biceps tendon; these patients underwent concomitant biceps tenotomy. Patients were evaluated clinically and radiographically at a mean 34-month follow-up (range, 24 to 48 months). RESULTS: The mean Constant score increased from 49 points preoperatively to 80 points postoperatively (P < .0001). Nine patients were satisfied or very satisfied with the results. Preoperatively, 2 patients had mild glenohumeral arthritis. Postoperatively, radiographs demonstrated no progression of arthritis and no new-onset arthritis in these 2 patients. CONCLUSIONS: The combination of arthroscopic debridement and biceps tenotomy in the treatment of subscapularis tears with biceps disease in selected patients yields good objective improvement and a high degree of patient satisfaction. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Risk factors for recurrence of shoulder instability after arthroscopic Bankart repair.

BACKGROUND: The higher failure rates reported with arthroscopic stabilization of traumatic, recurrent anterior shoulder instability compared with open stabilization remain a concern. The purpose of this study was to evaluate the outcomes of arthroscopic Bankart repairs with the use of suture anchors and to identify risk factors related to postoperative recurrence of shoulder instability. METHODS: Ninety-one consecutive patients underwent arthroscopic stabilization for recurrent anterior traumatic shoulder instability. The mean age (and standard deviation) at the time of surgery was 26.4 +/- 5.4 years. Seventy-one patients were male. Seventy-nine patients were involved in sports (forty, in high-risk sports). Capsulolabral reattachment and capsule retensioning was performed with use of absorbable suture anchors (mean, 4.3 anchors; range, two to seven anchors). All patients were prospectively followed, and, at the time of the last review, the patients were examined and assessed functionally by independent observers. RESULTS: At a mean follow-up of thirty-six months, fourteen patients (15.3%) experienced recurrent instability: six sustained a frank dislocation and eight reported a subluxation. The mean delay to recurrence was 17.6 months. The risk of postoperative recurrence was significantly related to the presence of a bone defect, either on the glenoid side (a glenoid compression-fracture; p = 0.01) or on the humeral side (a large Hill-Sachs lesion; p = 0.05). By contrast, a glenoid separation-fracture was not associated with postoperative recurrent dislocation or subluxation. Recurrence of instability was significantly higher in patients with inferior shoulder hyperlaxity (p = 0.03) and/or anterior shoulder hyperlaxity (p = 0.01). On multivariate analysis, the presence of glenoid bone loss and inferior hyperlaxity led to a 75% recurrence rate (p < 0.001). Lastly, the number of suture-anchors was critical: patients who had three anchors or fewer were at higher risk for recurrent instability (p = 0.03). CONCLUSIONS: In the treatment of traumatic recurrent anterior shoulder instability, patients with bone loss or with shoulder hyperlaxity are at risk for recurrent instability after arthroscopic Bankart repair. At least four anchor points should be used to obtain secure shoulder stabilization.

Repair of tears of the subscapularis. Surgical technique.

BACKGROUND: Rotator cuff tears involving the subscapularis are less common than those involving the superior aspect of the rotator cuff. The purpose of the present study was to report the results of repair of isolated tears of the subscapularis. METHODS: The records on eighty-four shoulders that had undergone open repair of the subscapularis tendon were reviewed. The mean age of the patients at the time of surgery was 53.2 years. The mean interval from the onset of symptoms to the time of surgery was 12.5 months. Fifty-seven tears were traumatic, and twenty-seven were degenerative. Twenty-three tears involved the superior one-third of the subscapularis tendon, forty-one tears involved the superior two-thirds, and twenty tears were complete. Fifty-four shoulders had a dislocation or subluxation of the long head of the biceps tendon, and ten shoulders had a rupture of the long head of the biceps tendon. Forty-eight shoulders underwent concomitant biceps tenodesis, thirteen shoulders underwent concomitant biceps tenotomy, and four shoulders underwent concomitant recentering of the biceps. Patients were evaluated clinically and radiographically at a mean of forty-five months (range, twenty-four to 132 months) postoperatively. RESULTS: The mean Constant score increased from 55.0 points preoperatively to 79.5 points postoperatively. Seventy-five patients were satisfied or very satisfied with the result. Preoperatively, four shoulders had mild glenohumeral arthritis. Postoperatively, twenty-five shoulders had mild glenohumeral arthritis and two shoulders had moderate glenohumeral arthritis. Tenodesis or tenotomy of the biceps tendon at the time of subscapularis repair was associated with improved subjective and objective results, independent of the preoperative condition of the biceps tendon. CONCLUSIONS: Repair of isolated subscapularis tears yields acceptable improvement in shoulder function in selected patients. Additionally, the results of the present study support routine tenodesis or tenotomy of the long head of the biceps tendon at the time of subscapularis repair.

Arthroscopic tenodesis for lesions of the long head of the biceps.

OBJECTIVE: Resection of the intraarticular part of the long head of the biceps and tenodesis to decrease shoulder pain due to a pathologically altered biceps tendon and to improve shoulder function. INDICATIONS: Tenosynovitis. State of prerupture. Instability (subluxation or dislocation of tendon from intertubercular groove). Intraarticular entrapment secondary to hypertrophy of the long head of the biceps in the presence of an intact cuff. To be performed during arthroscopic cuff repair or during debridement of an irreparable cuff tear. CONTRAINDICATIONS: Very thin, frayed, almost ruptured biceps tendon. Complete rupture of the long head of the biceps. SURGICAL TECHNIQUE: Standard arthroscopy with 30 degrees scope inserted through the posterior portal. Detachment of the long head from the glenoid origin. Longitudinal opening of the bicipital groove. Exteriorization and doubling of the tendon. Drilling of a socket starting in the groove but perforating the posterior cortex only with a guide wire. Passing of the tendon in an anteroposterior direction and securing the anchorage with a bioresorbable PLA interference screw. RESULTS: Between 1997 and 1999, an arthroscopic tenodesis was performed in 43 patients. Minimum follow-up 2 years. The absolute Constant Score improved from 43 points preoperatively to 79 points at the time of follow-up. No loss of elbow extension or flexion; power of biceps after tenodesis 90% of opposite side. Early on, two failures of tenodesis occurred.

Quality of life among disease-free survivors of rectal cancer.

PURPOSE: To identify factors affecting the quality of life (QoL) of disease-free survivors of rectal cancer. PATIENTS AND METHODS: One hundred twenty-one patients in complete remission more than 2 years after diagnosis were asked to complete three QoL questionnaires: the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30; its colorectal module, QLQ-CR38; and the Duke generic instrument. RESULTS: Patients reported less pain (P =.002) than did controls drawn from the general population. EORTC QLQ-C30 physical scores were also higher among rectal cancer survivors than in the general Norwegian or German population (P =.0005 and P =.002, respectively). Unexpectedly, stoma patients reported better social functioning than did nonstoma patients (P =.005), with less anxiety (P =.008) and higher self-esteem (P =.0002). In the present authors' experience, the QLQ-CR38 does not discriminate between these groups. Residual abdominal or pelvic pain and constipation had the most negative influence on QoL. CONCLUSION: QoL is high among rectal cancer survivors, including stoma patients. Simultaneous use of several QoL questionnaires appears to have value in follow-up and in monitoring the effects of therapy. The impact of residual pain and constipation on long-term QoL should be considered when establishing a treatment regimen.

Arthroscopic tenotomy of the long head of the biceps in the treatment of rotator cuff tears: clinical and radiographic results of 307 cases.

The purpose of this study is to evaluate the objective, subjective, and radiographic results of arthroscopic biceps tenotomy in selected patients with rotator cuff tears. Three hundred seven arthroscopic biceps tenotomies were performed in patients with full- thickness rotator cuff tears. Patients were selected for arthroscopic tenotomy if the tear was thought to be irreparable or if the patient was older and not willing to participate in the rehabilitation required after rotator cuff repair. Patients were evaluated clinically and radiographically at a mean of 57 months' follow-up (range, 24-168 months). The mean Constant score increased from 48.4 points preoperatively to 67.6 points postoperatively ( P < .0001). Eighty-seven percent of patients were satisfied or very satisfied with the result. The acromiohumeral interval decreased by a mean of 1.3 mm during the follow-up period and was associated with a longer duration of follow-up ( P < .0001). Preoperatively, 38% of patients had glenohumeral arthritis; postoperatively, 67% of patients had glenohumeral arthritis. Concomitant acromioplasty was statistically associated with better subjective and objective results only in patients with an acromiohumeral distance greater than 6 mm. Fatty infiltration of the rotator cuff musculature had a negative influence on both the functional and radiographic results ( P < .0001). Arthroscopic biceps tenotomy in the treatment of rotator cuff tears in selected patients yields good objective improvement and a high degree of patient satisfaction. Despite these improvements, arthroscopic tenotomy does not appear to alter the progressive radiographic changes that occur with long-standing rotator cuff tears.

Glenoid corticocancellous bone grafting after glenoid component removal in the treatment of glenoid loosening.

Nine patients underwent removal of a loose glenoid component and corticocancellous iliac crest autografting of the bony defect. No revision glenoid components were inserted. Eight bony defects were large, central, and cavitary, and one had an additional peripheral component. Patients were evaluated with a subjective assessment, Constant score, and radiographs at a mean follow-up of 30 months (range, 24-39 months). By use of Neer criteria, the result was considered satisfactory in 5 patients and unsatisfactory in 4. Functional improvement was modest, with the mean Constant score increasing from 46.3 to 49.9 points. Radiographs revealed a mean 4.1 mm of medialization of the humeral head within the glenoid (range, 1-11 mm). Two cases showed wear of the bone graft, thought to be induced by eccentric glenoid loading due to rotator cuff insufficiency. No other case demonstrated wear or graft resorption. One patient required reoperation for a massive rotator cuff tear; at the time of surgery, excellent glenoid bone continuity was observed, allowing implantation of a reverse prosthesis. Corticocancellous autografting appears to be a reliable procedure for restoration of glenoid bone stock after removal of a loose glenoid component. Although functional gains were modest, restoration of the glenoid bone component allows implantation if deemed necessary.
