ABSTRACT
Background: Distal radius morphometry (radial inclination, palmar tilt, radial height, and ulnar variance) is an important parameter in the evaluation and treatment of distal radius fractures in which anatomical alignment must be corrected. Currently, treatment of distal radius fractures in Indonesia is still based on morphometry of western population or from the contralateral side. The aim of this study is to determine distal radius morphometry of Indonesian population and to compare between right and left side, male and female gender. Methods: Distal radius morphometry was measured from 400 plain X-ray of right and left wrist AP and lateral projection. Samples were taken consecutively in Moh. Ridwan Meuraksa Army Hospital, Jakarta, from June to September 2010. Radial inclination, palmar tilt, radial height, and ulnar variance was measured. Data were recorded using tables and grouped between male and female, right and left side, statistical analysis was performed using Mann-Whitney test. Results: From 400 plain X-ray evaluated, there were 300 males and 100 females with the mean age of 25.5 years old (18-48). The mean of radial inclination was 23.99 ± 3.75°, palmar tilt 13.76 ± 4.36°, radial height 11.31 ± 1.66 mm, and ulnar variance -0.45 ± 2.03 mm. There were statistically significant differences between right and left side of radial inclination, palmar tilt, radial height, and ulnar variance. There was also statistically significant difference between male and female. Conclusion: Distal radius morphometry in Indonesian population may provide valuable data for the treatment of distal radius fractures. The use of contralateral side as reference should be reconsidered.

PURPOSE: The purpose of this study was to evaluate and compare the clinical & radiological outcome between LCP and conventional T-plate fixation in the treatment of distal radial fracture. MATERIALS AND METHODS: From January 2000 to October 2006, 26 patients were treated by LCP fixation and 20 patients were treated by conventional T-plate fixation for distal radial fracture. We used the X-ray to calculate the radial inclination, radial length and volar tilting, then compared the loss of correction after the operation between both groups. We also evaluated the clinical functional outcome by Mayo wrist score. RESULTS: The average follow-up since operation was ten months in both LCP and conventional T-plate fixation group. According to Frykmann classification, there were 1 case of type 1 (4%), 2 of type 2 (8%), 5 of type 3 (19%), 14 of type 4 (54%), 1 of type 5 (4%), 2 of type 7 (8%), 1 of type 8 (4%), and to AO classification, 4 of type A (15%), 22 of type C (85%) in LCP group. In conventional T-plate group, according to Frykmann classification, there were 12 cases of type 3 (60%), 4 of type 4 (20%), 3 of type 7 (15%), 1 of type 8 (5%), and to AO classification, 6 of type B (30%), 14 of type C (70%). In LCP group, the loss of correction between immediate post-operation and last follow-up was about 1.03 degrees in radial inclination, -1.09 mm in radial length, -2.08 degrees in volar tilting at each, and in conventional T-plate group, 2.4 degrees in radial inclination, -0.82 mm in radial length, -2.11 degrees in volar tilting at each. There was no statistical significance (p>0.05) in two groups. In the clinical functional outcome (according to Mayo wrist score), 92% of patient showed above good result in LCP group and 85% of patient showed above good result in conventional T-plate group. There was no infection, delayed union. CONCLUSION: Treatment by Interposition of fragments and shortening in the intractable nonunion of humerus with a bony defect can achieve not only good functional result, shortened bone union time and improved in shoulder and elbow motion.
