Abstract

PURPOSE: To analyze radiological and functional results after open reduction and internal fixation for fractures of the neck of humerus (4-part) using cannulated screws. MATERIAL AND METHODS: Between January 1997 and April 2004, 11 patients with neck of humerus fracture (4-part) were treated operatively by open reduction and internal fixation with cannulated screws. Two surgical approaches (deltopectoral for 9 cases and deltoid splitting for 2 cases) were used. The mean age was 36 years old and the mean duration of follow-up was 56 months. ASES (American Shoulder and Elbow Surgeons) score was checked to evaluate the function in shoulder joint. We used 2 cannulated screws in 2 cases, 3~4 screws in 6 cases and over 5 screws in 3 cases for fixation. In 2 cases, K-wires were used additionally and autoiliac bone graft was done in 1 cases which had poor bone mass.
RESULTS
All cases got bony union at 5.6 months on average. In functional assessment of shoulder, eight patients got excellent, one got good points. There were complications including shoulder stiffness in 2 cases, avascular necrosis of humeral head in 1 case and subacromial impingement syndrome in 1 case.
CONCLUSION
Internal fixation using cannulated screws for fractures of humerus neck (4 part) showed good bony union and functional results in patients under 50 years old who had average bone quality.
