Steinmann pin arthrodesis for salvage of failed small joint arthroplasty.

Proximal interphalangeal joint arthroplasty has been performed since the 1960s, with good short-term and medium-term results. However, despite improvements in pain, there is a considerable failure rate. Often, there is a delicate soft tissue envelope and substantial bone loss after removal of these prostheses, making salvage procedures difficult.

Effect of corticosteroids on the biomechanical strength of rat rotator cuff tendon.

Background: The effect of corticosteroids on tendon properties is poorly understood, and current data are contradictory and diverse. The biomechanical effect of steroids on rotator cuff tendon has not been studied, to our knowledge. The current study was undertaken to characterize the biomechanical effects of corticosteroid exposure on both uninjured and injured rat rotator cuff tendon.

Merkel cell tumor of the hand: report of two cases.

Merkel cell carcinoma is a rare cutaneous neuroendocrine neoplasm. Often located on the head and neck, reports of Merkel cell carcinoma in the hand are extremely limited.
