Importance of detection of capitellar cartilage injuries concomitant with isolated radial head fractures: A retrospective clinical study.

Objective: This study aimed to analyze the injury pattern and clinical importance of concomitant capitellar cartilage defects (CCDs) among patients treated surgically for radial head fracture (RHF).

Methods: A total of 74 patients who were treated surgically for isolated RHFs were retrospectively reviewed. Of these, 12 patients with CCDs (16.

Carpal Tunnel Syndrome Caused by Lipofibromatous Hamartoma of the Median Nerve.

Lipofibromatous hamartoma (LFH) is a rare tumor of the peripheral nerves, which usually involves the median nerve. The authors reported on two rare cases of carpal tunnel syndrome due to LFH of the median nerve. A 49-year-old female patient complained of the mass and symptoms consistent with LFH.

Two-dimensional Morphological Characteristics of the Distal Radius on Axial Magnetic Resonance Image and the Effects on Distal Screw Length.

Background: Detection of dorsal cortical penetration of distal locking screws is difficult owing to the irregular shape of the dorsal surface of the distal radius. This study was designed to analyze two-dimensional morphological characteristics of the distal radius on axial magnetic resonance image, and to suggest a guideline for evaluation of screw length in distal radius fractures on the fluoroscopic or plain X-ray true lateral image.

Methods: Anteroposterior length and lateral width of the distal radius, distance between the highest and the lowest point of the dorsal cortex (deceptive length), and widths of the first to second (hazard zone) and the third to fifth extensor compartments (safe zone) at the Lister tubercle level were measured on 104 axial magnetic resonance images by two hand surgeons.

Treatment of Kienböck's disease using a fourth extensor compartmental artery as a vascularized pedicle bone graft.

Background: Vascularized bone grafts for the treatment of Kienböck's disease may facilitate revascularization and remodeling of the avascular lunate. The aim of this study was to evaluate the radiological and clinical results obtained when a fourth extensor compartmental artery (ECA) bone graft was used to treat Kienböck's disease.

Methods: Between May 2009 and June 2012, 13 patients (6 men, 7 women) with Kienböck's disease were treated with placement of fourth ECA vascularized bone grafts.

Multiple etiologies of trigger wrist.

Background: Trigger wrist, a relatively unusual condition, is a triggering at the wrist produced by wrist or finger motion. The clinical manifestations and surgical results of trigger wrist with multiple etiologies were evaluated.

Methods: From October 2008 to December 2012, this study retrospectively reviewed 15 patients diagnosed with trigger wrist.

Spontaneous anterior interosseous nerve syndrome: clinical analysis of eleven surgical cases.

The aetiology of anterior interosseous nerve (AIN) syndrome and an optimal treatment strategy remain controversial. Eleven patients with spontaneous AIN syndrome, who were treated by surgical exploration, were reviewed at a mean of 32.5 months after the operation.
