PURPOSE The purpose of this study was to examine incidence of recompression and risk factors in the patients with osteoporotic vertebral compression fracture (OVCF) after vertebroplasty or kyphoplasty. MATERIALS AND METHODS This study was conducted on 179 vertebral bodies of 126 patients who underwent vertebroplasty or kyphoplasty on OVCF from January 2004 to August 2013. RESULTS When anterior vertebral height of fractured vertebrae declined by more than 3 mm from the height immediately after vertebroplasty or kyphoplasty, it was judged that recompression had occurred. Recompression was observed in a total of 58 vertebrae (32.4%). Recompression occurrences were found to be decreasing significantly when fractured vertebrae were the thoracic spine. In addition, osteonecrosis occurred in the preoperative vertebrae and restoration degree of anterior vertebral height immediately after vertebroplasty or kyphoplasty affected recompression occurrences significantly. The other factors (age, sex, bone mineral density, steroid medication history, follow-up duration, cement volume, vertebroplasty or kyphoplasty, and approach method) were compared, but no statistical significance was found. CONCLUSION The risk of vertebral recompression is more common, especially when osteonecrosis occurred in preoperative vertebrae or when vertebroplasty or kyphoplasty achieved remarkable restoration of anterior vertebra height. When performing vertebroplasty or kyphoplasty, such conditions should be considered carefully.

PURPOSE : To evaluate the results after rigid fixation for intraarticular distal humerus fractures and determine the prognostic factors influencing outcome. MATERIALS AND METHODS : Twenty-two patients were managed with the rigid fixation using dual plate or one plate combined with cannulated screw. According to the M ller's classification, eleven cases were classified as type C1; five, as type C2; and six, as type C3. Based on the age, the patients were divided into two groups as a guideline of 50 years so that the number of the patients was 11 cases respectively.
RUSULTS : By the rating scale from Aitken and Rorabeck, excellent or good results were 90% in type C1, 80% in type C2 and 66% in type C3. All patients who were under 50 years of age obtained excellent or good results, and group who were older than 50 showed 64% good results. CONCLUSION : Rigid fixation using dual plate and early mobilization using functional brace were considered to be a good method for intraarticular distal humerus fractures. And, this study revealed that comminution of fracture and age became an important factors in achieving the desire results.
