Treatment of Simple Bone Cyst

Abstract

Supracondylar fracture of the humerus is the one of the commonest elbow fracture in children. There are much controversies surrounding the method of treatment for various and frequent complications such as cubitus varus and joint stiffness, etc. For the period of 2 years and 8 months from Jan. 1987 to Aug. 1989, 32 patients had undergone treatment at the Department of Orthopaedic Surgery, Choongang Gil Hospital. Ten cases among them were treated with close reduction and cast, 8 cases were treated with close reduction and pinning, and 14 cases were treated with open reduction and internal fixation. The results obtained are as follows; l. Of all fractures, extension type was 96.9%, and flexion type was 3.1%. According to the Holmberg classification, 5 cases belong to Group I (15.6%), 10 to Group II (31.3%), 7 to Group III (21.9%), and 10 to Group IV (31.3%). 2. Radial nerve injuries which now are thought to be neuropraxia were the most common form of concomitant injuries. 3. All fractures were found to obtain bone union with mean duration of bone union about 40.9 days. 4. There were 7 cases (21.9%) who had more than 10 degrees of elbow motion limitation. Three cases (9.4%) showed the change of carrying angle over 10 degrees in Group IV by Holmberg classification. 5. By the modified Mitchell and Adams' criteria for grading results, Excellent was 22 cases (68.7%), Good was 7 cases (21.9%), Fair was 2 cases (6.3%), and Poor was 1 case (3.1%). 6. In Holmberg classification, the higher severity, the longer mean duration of bone union and the higher joint stiffness made the prognosis worse.
