Most fractures of the proximal humerus respond satisfactorily to conservative treatment, however operative treatment is indcated in certain types of displaced surgical neck fracture Three displaced fractures of humerus surgical neck(Neer Group III) were treated with closed reduction and percutaneous pinning, and 4 cases were treated with open reduction and pinning from October 1987 to October 1990 at the Our Lady of Mercy Hospital. Catholic University Medical college.
The results were as follows :
1. Six out of 7 patients were male. and the average age of the patients was 30 years (from 8 to 58 years) Causes of fracture were failing down (4 cases) and motor vehicle accident (3 cases).
2. After closed (3 patients) or open reduction through a limited intision (4 patients), multiple K-wires or Steinmann pins (average 3 in number) were inserted to enable early mobilization by providing stability at fracture site.
3. Open reduction was peformed for the cases in which closed reduction was failed because of interposition of the periosteal sleeve or the long head of Biceps brachii mustle.
4. Range of motion exercise was started from 3 to 4 weeks after the operation. The shoulder motion was regained full in all patients except one who had a slight limitation of abduction. There was one case of K-wire loosening with pin tract infection.
5. Excellent result was obtained in 5 cases and satisfactory in 2 cases blr Neers numerical rating method.
