Three-dimensional Intralunate Arteries Visualization with Red Lead (PbO) Angiography.

Background: The etiology of Kienböck's disease is controversial, and the blood supply is a possible pathogenic factor. The red lead (Pb3O4) angiography with micro-computed tomography (micro-CT) of lunate to investigate intralunate arteries has rarely been reported. This study aimed to investigate a new, reasonable, and simplified technique to study the intraosseous arterial pattern of normal lunates.

Microstructure study of normal lunates with micro-computed tomography.

In order to study the microstructure characteristics of normal lunate bones, eight fresh cadaver normal lunates were scanned with micro-computed tomography. High-resolution images of the micro-structure of normal lunates were obtained and we analyzed the nutrient foramina. Then nine regions of interest (ROI) were chosen in the central sagittal plane so that we could obtain the parameters of trabecular bones of ROIs.

Methods: Retrospectively analyze the clinical documents of cases of digital gigantism of the foot. Twelve 12 cases with 13 feet in this study included 8 male and 4 female with an average 4.

[Clinical analysis of 73 cases of macrodactyly].

Objective: To analyze the clinical characteristics of 73 cases of macrodactyly.

Methods: Review the incidence, distribution, characteristic, X-rays, pathogenesis and treatment of involved digits on the base of the clinical documents of 73 macrodactyly which were treated from 1965 to 2006. Twenty-eight cases had been followed-up.

Restoration of thumb opposition by transposing the flexsor pollicis brevis muscle: thirteen-year clinical application.

Background: To repair late median nerve injury, many methods have been used in the past years. The aim of this study was to review a thirteen-year experience in restoration of thumb opposition by transposing flexor pollicis brevis muscle.

Methods: From July 1992 to August 2005, 63 patients without thumb opposition because of late median never injury were treated by transposing the flexor pollicis brevis muscle.
