Total shoulder arthroplasty versus hemiarthroplasty for rheumatoid arthritis of the shoulder: results of 303 consecutive cases.
Between January 1, 1976 and December 31, 1991, 195 total shoulder arthroplasties and 108 hemiarthroplasties were performed in 247 patients in patients with rheumatoid arthritis. One hundred and eighty-seven total shoulder arthroplasties and 95 hemiarthroplasties with complete preoperative evaluation, operative records, and minimum 2-year follow-up (mean, 11.6 years) or follow-up until revision were included in the clinical analysis. Twenty patients had died and 1 was lost to follow-up. ⋯ Glenoid periprosthetic lucency was present in 110 of 152 total shoulder arthroplasties (72%). The data from this study indicate that there is marked long-term pain relief and improvement in motion with shoulder arthroplasty. Among patients with an intact rotator cuff, TSA appears to be the preferred procedure for pain relief, improvement in abduction, and lower risk of revision surgery.

Adhesive capsulitis of the shoulder is a common disorder, yet literature on its natural history is limited. This study examined patient characteristics, treatment patterns, and response to treatment of the disease in a large series of patients with this condition. Charts of 234 patients treated at our institution for adhesive capsulitis were reviewed retrospectively. ⋯ External rotation improved from an average of 26 degrees +/- 16 degrees pretreatment to 59 degrees +/- 18 degrees posttreatment. With supervised treatment, most patients with adhesive capsulitis will experience resolution with nonoperative measures in a relatively short period. Only a small percentage of patients eventually require operative treatment.

Functional outcome of surgical treatment of symptomatic nonunion and malunion of midshaft clavicle fractures.
Disability caused by nonunited or malunited fracture of the midshaft clavicle is a rare condition that is expressed by local pain or neurovascular impairment. This condition is usually treated by reduction of the fracture and stable fixation with augmentation by autogenous bone graft. We evaluated the functional outcome in 13 patients who were treated by this method. ⋯ There was also evidence that the current Constant scores of the affected shoulders remained significantly lower than those of the normal contralateral side. Ten patients reported various degrees of pain, and only three patients were pain-free. We show that, although solid union after realignment of symptomatic nonunion or malunion of midshaft clavicle fractures is predictable, the patients can remain functionally impaired.

Temporal expression of 8 growth factors in tendon-to-bone healing in a rat supraspinatus model.
Growth factors play an important role in supraspinatus tendon-to-bone healing. The objective of this study was to evaluate the temporal expression of 8 different growth factors in tendon-to-bone healing in an animal model. We hypothesize that growth factors exhibit unique temporal profiles that correlate to specific stages in the acute process of the supraspinatus tendon. ⋯ Immunohistochemical staining was done using antibodies for basic fibroblast growth factor (bFGF), bone morphogenetic protein 12 (BMP-12), BMP-13, BMP-14, cartilage oligomeric matrix protein (COMP), connective tissue growth factor (CTGF), platelet-derived growth factor-B (PDGF-B), and transforming growth factor-beta1 (TGF-beta1). Immunoassays showed an increase in the expression of all growth factors at 1 week, followed by a return to control or undetectable levels by 16 weeks in both the insertion and midsubstance. Future studies will investigate the different impacts of growth factor expression in tendon to bone healing.

Comparative StudyComparison of elbow contracture release in elbows with and without heterotopic ossification restricting motion.
We compared 16 patients with post-traumatic heterotopic ossification (HO) restricting elbow motion (but not complete bony ankylosis) after elbow trauma with 21 patients with capsular contracture alone to test the hypothesis that HO is associated with diminished motion after release. Patients with burns or head injury were excluded. ⋯ After all subsequent procedures (including procedures to address residual stiffness in 1 patient in the HO cohort and 4 patients in the capsular contracture cohort), the flexion arc averaged 116 degrees in the HO cohort and 98 degrees in the capsular contracture cohort (P = .19). Open release of post-traumatic elbow stiffness is more effective when HO hindering motion is removed than when there is capsular contracture alone.
