PURPOSE To evalute the anatomical and functional outcome after treatment for proximal humerus fracture according to surgical and conservative treatment and assess the final results according to treatment methods. MATERIALS AND METHODS Forty-two cases with follow-up over 12 months were divided into three groups: conservative treatment (Group 1, 20 cases), closed reduction with Rush or percutaneous pin fixation (Group 2, 11 cases), proximal intramedullary interlocking nailing(Group 3, 11 cases). The functional outcome was obtained by modified neer method using self-assessed score paper and the anatomical outcome was obtained by paavolainen method using radiologic film score. Statistics in comparing with the result of each group was analized by variance analysis using Generalized Liner Model and Fisher?s exact test. RESULT Anatomical reduction was best obtained in group 3 (p< 0.05) and mean duration of bone union was 10.33 weeks. Functional score was also best obtained in group 3 (p<0.05). Complication was noted in 9 cases. There was only 1 case in group 3. In studing of overall outcome, the group 3 has good result than other groups. CONCLUSION Proximal intramedullary interlocking nailing in displaced proximal humerus fracture can be demonstrated as better method for anatomical reduction(p<0.05) than other methods because it can make insertion of locking screw ease with multiple direction for anatomical reduction and can provides a sufficient fixation for early rehabilitation and union , while minimizing complication.

Recently intramedullary nailing has become the most common method treating tibial fractures.
Reamed intramedullaiy nailing technique leaves the problem of destorying the endosteal blood supply, which associated with delayed union and postoperative infection. Recent reports have shown excellent rate of union and low rate of intection with unlearned interlocking intramedullary nail.
Author reviewed 58 cases of tibia shaft fractures that were treated with unrealned interlocking nail from Feb. 1992 to Feb. 1994.
1. Furty nine fractures were closed and 9 were open (Gustilo-Andersonl;3,II;5, IIIa;1). Thrity one fractures involved the distal portion, 19 fractures the middle portion, 6 fractures tile proximal portion and 2 fractures were segmental.
2. Thirty six cases were male and 22 were female. The most common age was 3rd decade (25.8%).
3. The most common caute was traffic accident.
4. Average interval from injury to operation were 5.7 days in close fracture and 11.3 days in open fracture.
5. The mean duration of bone union were 15.7 weeks in closed fracture and 19.5 wreks in open fracture.
6. Complications include 1 case of delayed union, 1 case of joint stiffness and 1 case of screw failure.
7. According to the functional results by Klemm and Borner, 42 cases were excellent, 15 cases were good and 1 was fair.
