PURPOSE: This study evaluated the clinical result of supracondylar fractures of the humerus treated with double tension band osteosynthesis. MATERIALS AND METHODS: From October 1992 to September 2001, 14 patients with supracondylar fractures of the humerus were treated by method of double tension band osteosynthesis. Eleven fractures were the results of slipped down injury and two traffic accidents and one direct trauma. All fractures were classified according to the AO fracture classification (A2; 2, A3; 1, C1; 6, C2; 3, C3; 2). There were 5 males and 9 females with average age of 51.6 years (range 15 to 88). Olecranon osteotomy was performed in 4 patients with severe comminuted fractures. Postoperative immobiliza-tions were required for an average of 20.6 days and consolidations were noted after an average of 10.1 weeks. Before operation, bone marrow density studies were performed in five fractures above 65 years. Average T-score of the patients were -3.65 on femur neck and -2.97 on lumbar spine. All patients were re-examined after an average of 16.4 months. RESULTS: Union and consolidation was achieved in all 14 patients with no secondary displacement. In range of motion, eight patients judged their results as excellent and four as good. Ten patients had no pain and four had only occasional discomfort. Early removal of K-wires was performed in one patient because irritation of one side K-wires were develop. Sensory change of the ulnar nerve was noted in two patients. Anterior transposition of ulnar nerve was performed in one patient and the other was improved spontaneously. Skin necrosis was developed in one patient but was healed after pin removal and conservative care. CONCLUSION: The advantages of double tension band wiring are an easier and faster procedure, less periosteal and muscle damage, and more symmetrical compression than double plating. Therefore, in the commiuted osteoporotic fracture with poor tolerance for internal fixation with the plate or the simple supracondylar fractures in young age, double tension band osteosynthesis can provide sufficient and secure stability to allow early functional exercise.
