Shoulder synovectomy.

Abstract

The technique and results of synovectomy of the shoulder joint in rheumatoid arthritis with a mean follow up time of 5.3 years (1-16 years) is described. The original method included resection of acromion after loosening of the deltoid muscle and splitting of the rotator cuff. Since 1981 the simpler approach of Neer without resection of acromion has been used (for synovectomy as well as for prosthetic replacement) with an easier postoperative management and equally good results. Only in 6 of 54 shoulders a total replacement prosthesis has been inserted later, an indication of the lasting good effect of synovectomy, even in advanced cases where an additional debridement was necessary. The best results are obtained in early cases. Radiographic changes are late, indications should be based more on clinical findings. Access to good training facilities is mandatory.

Modified and classic acromioplasty for impingement of the shoulder.

We compared the results of modified and classic anterior acromioplasty in order to identify the significance of the resected acromion. Fifty patients with shoulder impingement syndrome resistant to conservative therapy underwent surgical treatment. We treated 30 patients with classic Neer acromioplasty (group 1), and 20 patients with modified Neer acromioplasty (group 2). The patients were assessed according to pain and shoulder movement. Excellent or good results were achieved in 28/30 patients in group I and 19/20 patients in group 2. The results indicate that both surgical techniques are effective procedures in the treatment of shoulder impingement syndrome, and the type of bone resection does not influence the clinical outcome.

Trajectories of target reaching arm movements in individuals with spinal cord injury: effect of external trunk support.

DESIGN: Deficits in trunk control due to spinal cord injury (SCI) lead to slower target-reaching movements of the hand. We investigated whether the movement path is also affected, and whether providing external support for the trunk can abolish the kinematic differences. OBJECTIVE: To compare movement trajectories between individuals with SCI and neurologically normal individuals, with and without external trunk support. SETTING: Neural Control/Biomechanics Laboratory, University of Illinois, Chicago, USA. METHODS: Five subjects with levels of injury between C7 and T4 were tested 3-8 years post-injury, and compared with five control subjects. Two targets were employed. Trajectories were recorded by a motion-capture system using infrared emitting markers. Peak speed and path curvature were calculated for the fingertip and for the acromion. RESULTS: Compared with control subjects, the subjects with SCI exhibited lower peak speed of the fingertip but not of the acromion, and less straight paths for both. When the trunk was supported externally, the difference in fingertip speed persisted. The support abolished the difference in path curvature for the fingertip but accentuated that for the acromion. CONCLUSION: The slower hand movements of individuals with SCI are not simply time-scaled versions of those of normal subjects, and the provision of trunk support does not erase the kinematic differences between the reaching movements of the two groups.

The correlation between bursoscopic and histologic findings of the acromion undersurface in patients with subacromial impingement syndrome.

PURPOSE: Ideally, decompression of the coracoacromial arch in patients with shoulder impingement syndrome should be done only at the site of impingement. However, it is very difficult to determine the exact site of impingement before acromioplasty. The objectives of this study were to investigate the relationship between findings and the histopathologic changes of the undersurface of the acromion in subacromial impingement syndrome and to evaluate the usefulness of bursoscopy in identifying the site of the impingement. TYPE OF STUDY: Case series. METHODS: We investigated the correlation between subacromial bursoscopic findings and histopathologic changes of the coracoacromial arch in 50 patients with subacromial impingement syndrome. The acromion and the coracoacromial ligaments removed during acromioplasty were fixed in 10% formalin, decalcified, embedded in paraffin, and cut into sections along the direction of the coracoacromial ligament. After staining with toluidine blue, the specimens were evaluated for pathology using an optical microscope. RESULTS: The pathologic changes were classified into 3 types according to the direction of proliferative fibrocartilaginous changes at the enthesis of the acromial insertion of the coracoacromial ligament. The bursoscopic findings were classified into 4 types. Subacromial abnormalities in the bursoscopy findings correlated with histopathologic changes at the undersurface of the acromion. On the other hand, cases with normal findings on the undersurface of the acromion on bursoscopy had hypertrophic changes of fibrocartilage at the insertion of the coracoacromial ligament to the acromion. These results suggest that, with normal findings on the undersurface of the acromion in patients with subacromial impingement syndrome, there is impingement at the coracoacromial ligament. CONCLUSIONS: Bursoscopy is a useful procedure to determine the impingement site in patients with subacromial impingement.
