The reported prognosis for recovery after peripheral nerve injury is remarkably poor. Deficits may persist for years, resulting in significant functional disability. Both corticosteroids and Erythropoietin have been investigated as neuroprotective agents; however, their efficacy in total hip and knee arthroplasty is not known. The purpose of this study was to evaluate the effect of systemically-administered Erythropoietin and tapered oral corticosteroids on the recovery of postoperative nerve palsies in the setting of total hip and knee arthroplasty. ⋯ Therapeutic Level IV.

Comminuted proximal ulna fractures are rare and reconstruction of these fractures is discussed controversially. The aim of this study was to test three currently available plate devices in a standardized comminuted four-part fracture model created in proximal ulna sawbones. ⋯ The locked angle plate system showed the highest stability in 90° of elbow flexion. Each implant was more stable in 30° flexion than in 90° flexion. Testing of the anterior stability of the elbow did not show any differences between the different implants. Because of the superior stability of this device, we conclude that locked angle plating should be preferred for reconstruction of monteggia like complex proximal ulna fractures.

Achieving quiescence in chronic osteomyelitis remains challenging. Wide resection of all infected and necrotic tissues improves the chances of achieving remission of the disease. ⋯ Resolution of infection and humeral shaft union was achieved in all patients. Our study finds that two-stage reconstruction of stage IV chronic osteomyelitis with the use of circular external fixation is effective in achieving infection control and union in these complex cases.
