[Hand function reconstruction by tendon transfers in patients with cervical spinal cord injury].

Objective: To explore the effectiveness of functional reconstruction of hand grasp and pinch by tendon transfers in patients with cervical spinal cord injury.

Methods: Between July 2013 and January 2016, tendon transfer surgery were performed in 21 patients (41 hands) with cervical spinal injury that motion level was located at C to reconstruct hand grasp and pinch function. There were 18 males and 3 females with a mean age of 42.

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.

[Immunogenicity of allogeneic freezing periosteum and bone marrow].

Objective: To investigate the immunogenicity of freezing periosteum and bone marrow during allogeneic joint transplantation, and to explore proper pretreatment of allogeneic joint.

Methods: The allogeneic periosteum and bone marrow were harvested from knee joints of 5 New Zealand white rabbits (aged, 6 months; weighing, 2.6-3.

[Experimental study on protective effect of early motion on articular cartilage after joint allograft].

Objective: To investigate the protective effect of early motion on articular cartilage after joint allograft by performing a controlled trial between different post-operation strategies after joint allograft in an animal model.

Methods: Twenty hemi-knee joints were harvested from 10 6-month-old New Zealand white rabbits (male or female, weighing 2.5-3.

[An improved surgical strategy and treatment outcome of dorsal wrist ganglion].

Objective: To investigate the clinical outcome of treating dorsal wrist ganglion with an improved surgical strategy by excising the ganglion completely along their stalk and repairing the dorsal carpal ligaments under brachial anesthesia.

Methods: From March 2005 to January 2007, 34 patients with dorsal wrist ganglion were treated and studied retrospectively. There were 14 males and 20 females, aged 25-65 years (43 years on average).

[Digital gigantism of the foot: a clinical study of 12 cases].

Objective: To summarize the clinical characteristic and outcome of digital gigantism of the foot.

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.

[Analysis of reasons of tendon adhesion post tendon allograft].

Objective: To explore the reasons of tendon adhesions post tendon allograft.

Methods: From May 1990 to June 2000, 85 cases receiving tendon allograft were given tenolysis because of tendon adhesions. There were 76 males and 9 females, with an average age of 24.

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.
