Congenital Anomaly of the Atlas Misdiagnosed as Posterior Arch Fracture of the Atlas and Atlantoaxial Subluxation

Partial or complete absence of the posterior arch of the atlas is a well-documented anomaly but a relatively rare condition. This condition is usually asymptomatic so most are diagnosed incidentally. There have been a few documented cases of congenital defects of the posterior arch of the atlas combined with atlantoaxial subluxation. We report a very rare case of congenital anomaly of the atlas combined with atlantoaxial subluxation, that can be misdiagnosed as posterior arch fracture.

A Case of Arthroscopic Excision of Synovial Hemangioma with Dual Coagulation Shaver

A 17-year-old male patient visited our hospital with a palpable mass on the lateral aspect of the knee joint of five years duration without any related trauma history. The patient felt tenderness around the mass and had limitations in doing flexion exercises. Magnetic resonance imaging of the knee suggested the possibility of synovial hemangioma, and thus surgical treatment was planned. A tumor within the knee joint was found by arthroscopy, and a resection was carried out by dual coagulation shaver. The biopsy confirmed the diagnosis of a synovial hemangiomas. The patient presented months later at the out-patient clinic with no evidence of recurrence.

Treatment of Nonunion of Tibia with Extracorporeal Shock Wave Therapy: A Case Report

Almost tibia fractures can be surgically treated, but nonunion may occur in 10~30%, and they may accompany various complications by operation. This research was designed to review literatures and report a case of patient with nonunion of the tibia that showed good result when performing the extracorporeal shock wave therapy as a conservative treatment.

Extracorporeal Shockwave Therapy for Calcifying Tendinitis of Hands: Two Cases Report

Calcifying tendinitis of the hand is rare, and known to be self-limited or to show improvement with conservative therapy. However, poor response to treatment has been observed in cases of chronic conditions. The authors have performed extracorporeal shock wave therapy on a 19-year-old woman with chronic calcifying tendinitis of the extensor carpi ulnaris tendon, and a 45-year-old female with the condition involving the 4th finger flexor tendon, who showed no response to conservative treatment. Pain relief and radiological improvements were observed in the both patients.
