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.

PURPOSE The purpose of this study was to evaluate the relationship between variable factors and clinical results following the operative treatment of the tibial plateau fractures. MATERIALS AND METHODS The clinical and radiological analysis was performed on 29 cases of the tibial plateau fractures who had been treated with operative treatment and followed up for more than 1 year from January 1991 to December 1997. The analysis of clinical results was performed dividing into age, cause of injury, fracture type of Schatzker classification, associated soft tissue injury and method of operative treatment. RESULTS 18 of 19 cases that were ranged of ages between 30 years and 59 years showed good clinical results as criteria of Blokker. Schatzker type II was noted 11 cases(37.9%) as most common. 13 of 14 cases of the type I,II and III, were showed good clinical results, compare to 10 of 15 cases of the type IV,Vand VI. 12 of 18 cases which were related with associated soft tissue injuries, were showed good clinical results. CONCLUSION We could expect good clinical results if early knee joint mobilization following open reduction and rigid internal fixation could be obtained. Factors affecting clinical results are age, type of fracture, associated soft tissue injuries. Bad clinical results were related with young age group under 30 and over 60, more than Schatzker classification type IV of high energy trauma and associated injury of anterior cruciated ligment or meniscus.
