Peroperative samples identified Propionbacterium species (5), Coagulase-negative staphylococci (4), MRSA (1) and with E.Coli (1) infection. Monobacterial infection was seen in 6 shoulders, multibacterial in 2 shoulders and in 2 shoulders cultures were negative.
Recurrence rate of infection is comparable to the classical two-stage revision. Preoperative stiff and painful shoulders seems to have a bad prognosis despite definite cure of the infection. Supple shoulders (mainly associated with a fistula) can be treated with a good functional result.
One patient deceased, one patient developed Alzheimer dementia, leaving 34 patients available for follow-up. They completed the SF-36 questionnaire and the Simple shoulder test. They were clinically reviewed and scored with the Constant-Murley score. All 34 had complete radiographic work-up (x-ray; ultrasound) preoperatively and at final follow up.
Mean operating time was 35 minutes (SD: +/− 12.33). There were no surgical complications. Postoperatively, there was an uneventful recovery in all patients. At final follow-up, two patients were revised to a RSA. One patient was revised after 9 months because of continuous pain and loss of function. The second patient developed a complete osteonecrosis and was revised after one year. The 32 remaining patients had a preoperative Constant-Murley score adjusted for age and gender of 34,8. This improved to an average of 84 at final follow up. The simple shoulder test improved from an average of 1,8 to 8,4. The average decrease of subacromial space was 2,34 mm and the loss of glenohumeral joint space was 0,57. Finally, the preoperative grade of arthrosis was 0,46 compared to a postoperative average of 1,1. At final follow-up, 85% (27/32) were either satisfied or very satisfied with the result. 12,5% (4/32) appreciated the result as only fair. 2,5% (1/32) was dissatisfied, but didn’t consider revision surgery.
Over 40 months, 264 arthroscopic rotator cuff repairs were assessed prospectively. Preoperatively all patients were assessed using a modified Constant score and Visual Analogue Pain Scale (VAPS). The mean age at surgery was 59 years (19 to 83). In 151 cases (62%) the shoulders were on the dominant side. All patients underwent postoperative ultrasonography to assess cuff integrity at three weeks. Twenty-two patients were lost to follow-up. Of the rest, 210 were clinically reviewed and Constant scores produced. The remaining 32 were assessed using the VAPS and a subjective satisfaction questionnaire. The Constant score improved by a mean of 29.6, with 166 patients (69%) reporting complete resolution of pain. The subjective outcome was rated excellent by 162 patients, good by 55, moderate by 20 and poor by five. There were 13 retears, 11 of which were identified on the three-week ultrasound. When four of these were revised, two required subscapularis repair. Importantly, five patients with retears had excellent subjective outcome. Complications were five superficial infections, 13 cases of transient neuritis following interscalene nerve blocks, four cases of bursitis, which required debridement and suture removal, and two anchor pull-outs. The overall reoperation rate was 4%. Arthroscopic rotator cuff repair offers excellent objective and subjective outcomes, particularly pain relief. Ultrasonography at three weeks is a good indicator of whether or not a repair has taken.
The proximity of neural structures to the coracoclavicular ligaments limits the amount of coracoid process that can be harvested. The purpose of this study of 100 dry human scapulae was to define the anatomic limitations. We found the mean measurement of the horizontal arm of the coracoid process anterior to the conoid tubercle was 21.5 mm (SD 0.9 mm). In 10% of the scapulae, it was larger than 30 mm. In 66%, the posterior aspect of the conoid fused with the vertical ramus and the lateral lip of the suprascapular notch. This amount of coracoid appears to be large enough to expand the glenoid vault, and to hold two AO small fragment screws. It can be safely harvested if the conoid ligament is respected. Partial sacrifice of the trapezoid ligament is unavoidable, but does not compromise coracoclavicular stability. If the coracoid osteotomy is extended medial to the conoid tubercle it encroaches on the vertical ramus of the coracoid and can damage the suprascapular nerve. Posterior advancement of the osteotomy can extend onto the anterosuperior glenoid.
We evaluated the clinical outcome of arthroscopic labroplasty in 56 patients treated for shoulder instability owing to ligamentous laxity. In our technique, the antero-inferior labral capsular complex is detached and mobilised from the glenoid. It is advanced superiorly and plicated to create a new labrum, retensioning the capsule and decreasing the articular volume. Usually, a rotator interval plication is also added. Postoperatively, patients wear an adduction sling for three weeks, but movement is permitted within pain limits. The mean time to follow-up, when patients were clinically reviewed and assessed on the Walch-Du Play score, was 26 months (12 to 74). No intra-operative complications or nerve injuries were encountered. There was a single failure with frank redislocation. The mean Walch-Du Play score was 88/100 (10 to 100). Redundant capsule and a hypoplastic labrum are common in unstable shoulders owing to ligamentous laxity. The labroplasty creates a ‘bumper’ and addresses the excess of capsule. In our short-term experience, this arthroscopic technique is superior to the open capsular shift.
Between 1996 and 2001 we used a modification of the Latarjet procedure to treat 70 patients with bony insufficiency of the glenoid. Our modification involves detaching a long piece of coracoid and rotating it to match its concave inferior surface with the surface of the glenoid. The coracoid graft is placed extra-articularly and the capsule repaired with bone anchors to the edge of the glenoid. Postoperatively no sling is applied and rehabilitation is started early. At a mean of 24 months (9 to 72) patients were clinically reviewed and assessed on the Walch-Du Play score. The results were excellent in 68%, moderate in 6% and poor in 1%. There were no redislocations. The results were most satisfactory in this group of patients, most of whom participated in contact sports, where soft tissue procedures (e.g., open and arthroscopic Bankarts) carry unacceptable failure rates.
