Comparative Study of Outcomes between Operative and Non-Operative Treatment of Unstable Distal Radius Fracture in the Elderly Patients

PURPOSE: The goal of this retrospective study is to compare radiologic outcome and clinical outcome between operative and non-operative treatment of unstable distal radius fracture in patients over 65-year-old. METHODS: From December 2006 to December 2011, 114 patients over 65-year-old were enrolled in the present study. 45 patients underwent non-operative treatment, and 69 patients underwent operative treatment. We retrospectively reviewed radiologic results and clinical results and then compared the two groups. Radiologic results include radial inclination (RI), volar tilt angle (VT) and radial shortening (RS) shown on the last radiograph and clinical results including disabilities of the arm, shoulder and hand (DASH) scores, modified Mayo wrist score (MMWS), and range of motion (ROM) of wrist. RESULTS: All cases presented bone-union. Among the patients who received non-operative treatments, average RI of 15.5degrees, average VT of 14.1degrees, average RS of 5.3 mm, The patients who received operative treatments showed average volar tilt of 3.9degrees, average VT of 18.2degrees, and average RS of 1.1 mm. RS showed a significant difference (p0.05). CONCLUSION: Our results suggest that non-operative treatment is initially recommended in patients over 65 years who have an unstable distal radius fracture in terms of functional results.

Analysis of Low-Energy Trochanter Fracture Using the Multiplanar Computed Tomography Image: Application for Intramedullary Nail Fixation

PURPOSE: The purpose of this radiologic study was to evaluate the geographic patterns of low-energy trochanteric fractures using multiplanar computed tomography (CT) images for application of intramedullary nailing. MATERIALS AND METHODS: In this study, 117 trochanteric fractures (stable fracture, 39 cases, unstable fractures, 78 cases) sustained from simple slip-down were assessed. The mean age was 78.4 years (range, 60-96 years). Multiplanar CT images were assessed for evaluation of geographic features of trochanteric fracture, and the fracture exit and geographic patterns were analyzed. RESULTS: The medial and lateral exit of the trochanteric fracture showed no statistical difference by age, bone density, and comorbid disease. The exit was located at an average distance of 10.2 mm (range, 1.0-22.2 mm) from the tip of the greater trochanter (GT), and the medial exit, average distance of 8.1 mm (range, 0.0-18.3 mm) from the tip of the lesser trochanter. It was also found that there was no comminution around the anteromedial cortex of the fracture, and its contact loss was from fracture deformity. CONCLUSION: Because of no comminution, the contact restoration of the anteromedial cortex resulted in correction of fracture deformity and reduction. Trochanteric nailing by GT tip could be fixed through the proximal fragment of the fracture because the lateral exit is placed at an average distance of 10.2 mm from the GT tip.

Early Result of Demineralized Bone Matrix (DBM, Genesis(R)) in Bone Defect after Operative Treatment of Benign Bone Tumor / 대한골관절종양학회지

PURPOSE: This study was performed to evaluate the efficiency of demineralized bone matrix (DBM, Genesis(R)) used for bone defect after operative traetment of benign bone tumors by clinical and radiological methods. MATERIALS AND METHODS: DBM was used to treat bone defect after operative treatment of benign tumor from February 2012 to May 2013. Total 25 benign bone tumor cases (15 males, and 10 females) with mean age of 30.3 were studied. The diagnoses were solitary bone cyst in 9 cases, non ossifying fibroma in 5, fibrous dysplasia in 5, aneurysmal bone cyst in 3 and enchondroma in 3. In categorization by location of tumor, there were 5 cases of distal femur, 4 of proximal tibia, 3 of proximal femur, 3 of proximal humerus, 3 of phalanx, 2 of distal radius, 2 of hip bone, 2 of calcaneus, and 1 of scapula. Autogenous bone was used with DBM in 6 cases, and only DBM used in 19 cases. Mean periods of follow up were 8.7 months (range: 6 to 14 months). Amount of graft resorption and bone formation was observed with compare of post operation radiograph and the difference was shown by percentage. Resorption level was measured by DBM level which could be observed from simple x-ray, and bone formation level by bone trabecular formation level at impaired site. RESULTS: Twenty three cases of total 25 cases showed bone union. In the 23 cases, more than 98% DBM resorption was observed after mean 4.3 months, and more than 98% bone formation was observed after mean 6.9 months. Lesser bone defect sizes showed faster bone formation and it was statistically significant (p=0.036). But other comparative studies on other factors such as, sex, age of patients and combination of autogenous bone were no statistically significant differences in graft resorption and bone formation. And there was no significant complication in periods of follow-up. CONCLUSION: Demineralized Bone Matrix (Genesis(R)) is thought to be useful treatment for bone defect after operative treatment of benign bone tumor, however longer follow-up periods appears to be needed.
