Autologous Costal Cartilage Grafting for a Large Osteochondral Lesion of the Femoral Head: A 1-Year Single-Arm Study with 2 Additional Years of Follow-up.

Background: There is currently no ideal treatment for osteochondral lesions of the femoral head (OLFH) in young patients.

Methods: We performed a 1-year single-arm study and 2 additional years of follow-up of patients with a large (defined as >3 cm 2 ) OLFH treated with insertion of autologous costal cartilage graft (ACCG) to restore femoral head congruity after lesion debridement. Twenty patients ≤40 years old who had substantial hip pain and/or dysfunction after nonoperative treatment were enrolled at a single center.

Internal fixation using fully threaded cannulated compression screws for fresh femoral neck fractures in adults.

Objectives: Internal fixation with multiple cannulated compression screws is an optional treatment for femoral neck fracture. Recently, fully threaded cannulated compression screws (FTCCS) have been introduced to fix fresh femoral neck fractures (FNF). The purpose of this study was to investigate the effectiveness of FTCCS.

Chronic carpal tunnel syndrome caused by covert tophaceous gout: A case report.

Carpal tunnel syndrome (CTS) is well recognized as the most common type of peripheral neuropathy. A rare cause of CTS is tophaceous gout. Tophi deposits can accumulate in various structures including the flexor tendons, tendon sheaths, the carpal tunnel floor, transverse carpal ligament, and even the median nerve, causing various symptoms such as pain, numbness, and weakness.

Results of intercostal nerve transfer to the musculocutaneous nerve in brachial plexus birth palsy.

Background: Intercostal nerve (ICN) transfer has been one of the main extraplexal nerve transfers in treating brachial plexus root avulsion. This retrospective study evaluated results of ICN transfer for reconstruction of the musculocutaneous nerve (MCN) in brachial plexus birth palsy (BPBP).

Methods: Eighteen boys and 6 girls with BPBP, who had avulsion of at least 2 spinal nerves of the plexus, underwent ICN transfer for reconstruction of MCN, from March 2003 to October 2005.

[Repaired ulnar nerve and effect on its innervating muscles in rat].

Objective: To study the morphological changes of the rat claw inner skeletal muscle after ulnar nerve injury at different sections and different recovery times.

Methods: Forty-two adult male Sprague-Dawley rats were selected and placed randomly in seven groups. After establishing model of injury and repair of claw inner skeletal muscle by cutting off the ulnar nerve, the muscle wet weight, cross section area of myocytes, and collagen fibers were measured.

[Anatomy study of MGA in Chinese and its effect on legal expertise].

Objective: This study aimed to clarify the morphology of the Martin-Gruber anastomosis (MGA) in Chinese.

Methods: One hundred and five Chinese upper limbs (36 males and 20 femalese) were dissected to find the connections between medial nerve and ulnar nerve. The MGA was classified as previously described by Lee.
