Methods: Between 2005 and 2011, 19 consecutive patients (13 men, 6 women) with a mean age of 29 years (range, 13-52 y) were treated late for mallet finger fractures. The mean interval from injury to initial operation was 57 days (range, 28-141 d).

Current approaches for carpal tunnel syndrome.

With advancement in biomechanical and biological research on idiopathic carpal tunnel syndrome, the insight on the pathophysiology of carpal tunnel syndrome has gained much clinical relevance. Open carpal tunnel release is still a gold standard procedure for carpal tunnel syndrome, which has evolved into mini-open procedure with development of new devices. Endoscopic carpal tunnel release has become popular in recent practice of hand surgery with an advantage of early recovery of hand function with minimal morbidity.

Tension wire fixation for mallet fracture after extension block pinning failed.

Introduction: Various surgical treatments such as extension block pinning have been proposed for acute bony mallet finger. We evaluated the clinical results of tension wire fixation technique for the treatment of nonunion of mallet fracture after failed mallet finger surgery.

Nail-preserving excision for subungual glomus tumour of the hand.

Subungual glomus tumours can cause excruciating pain and nail deformity. Conventional surgical excision requires nail removal and, therefore, nail deformity often occurs. Because nail preservation prevents further damage to the nail bed, it is beneficial for patients from the perspectives of pain and cosmesis.

Osseous microarchitecture of the scaphoid: Cadaveric study of regional variations and clinical implications.

Bone strength and structure are closely associated with fracture and screw fixation, however osseous micro architecture on scaphoid has not been clearly addressed. We conducted histomorphometric study of the scaphoid using micro CT to find regional variations and differences in the scaphoid to provide better understanding of fracture mechanism and suggest optimal screw position. We divided scaphoid into eight regions and collected regional data from eleven different cadaveric scaphoids.

Surgical treatment and clinical implication for posterolateral rotatory instability of the elbow: Osborne-Cotterill lesion of the elbow.

Background: An osteochondral fracture in the posterolateral margin of the capitellum is recognized as being a cause of posterolateral rotatory instability (PLRI).

Methods: Five patients who presented with chronic PLRI of the elbow were associated with an osteochondral fracture in the posterolateral margin of the capitellum (Osborne-Cotterill lesion). All presented instability and deficient radiocapitellar articulation at extension.

Ultrasonographic evaluation of the shoulder in elite wheelchair tennis players.

Context: Wheelchair tennis has been identified as a high-risk sport for shoulder injury, so understanding shoulder pathology in these athletes is important.
