Abstract PDF: Post-traumatic avascular necrosis is a notorious complication of intracapsular fractures of the femoral neck, whether or not the fracture unites. The incidence of avascular necrosis of the femoral head following femoral neck fractures has been reported variably ranged from 7% to 84%. The purposes of this study are to analysis the clinical features of avascular necrosis of the femoral head following femoral neck fractures and to define causative factors of posttraumatic avascular necrosis. From May 1986 to May 1995, sixty-eight patients with intracapsular femoral neck fracture were operated on osteosynthesis in soonchunhyang University Hospital; we analysed retrospectively with follow-up more than two years, post-traumatic avascular necrosis(AVN) was developed in 13 patients(AVN group) and united forty-six patients were included non-avascular necrosis group, nine patients were excluded due to nonunion. Comparative study was performed between these two groups. The results were as follows: 1. The avascular necrosis of the femoral head following femoral neck fractures treated with osteosynthesis was noted in 13 cases (19%) 2. The eleven cases of 13 cases showed segmental collapse of the femoral head within 2 years. 3. Among the causative factors, age and sex, delay before operation and fixation device have no statistical significance(p>0.05) but type of fracture, initial displacement and quality of reduction showed to be statistical correlation(p<0.05). In conclusion, adequate reuction and internal fixation for the femoral neck fracture may essential to minimize avascular necrosis following osteosynthesis.

Treatment of Intertrochanteric Fractures of Femur in Elderly Patients over 65 Years Old: Yoo Seong Seo, Hyung Suk Choi, Sang Gi Kim, Byung Joon Shin, Soo Kyun Rah, Chang Uk Choi; J Korean Soc Fract 1995;8(1):54-60. Published online January 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.1.54

Abstract PDF: The ipsilateral femur fracture after hip arthroplasty is rare, but serious complication. And its treatment is difficult and controversial. We experienced 6 patients who had the hip arthroplasty complicated by an ipsilateral femur fracture in postoperative period at the Department of Orthopaedic Surgery, Soonchunhyang Univesity from February 1990 to December 1993. The Type 1 fracture was 1 case, and 2 Type IV-A, and 1 Type IV-3, and 2 Type V according to AAOS classification. Bony union and satisfactory clinical results were achieved in all 6 cases.

Cotrel-Dubousset Pedicular Screw in the Treatment of Unstable Dorsolumbar fracture: comparison with Harrignton SSI: Se Il Suk, Byung Joon Shin, Choon Seong Lee, Myung Chul Lee; J Korean Soc Fract 1989;2(1):91-100. Published online June 30, 1989; DOI: https://doi.org/10.12671/jksf.1989.2.1.91

Abstract PDF: Twenty four patients with unstable dorsolumbar spine fractures were treated with C-D pedicular screw from March 1987 to Dec. 1988 in Seoul National university Hospital and 19 patients were followed-up more than 4 months, average 7.9 months. The results of these 1 9 patients were compared with those treated with Harrington SSI from Feb. 1985 to March 1987 and following conclusions are obtained. 1. The average fixation with C-D pedicular screw was 2 segments. Even the short segments fixation, C-D pedicular screw gave better correction and stability of fractures as compared with Harrington SSI. 2. Anatomical reduction with restoration of normal spinal sagital curvature was possible using C-D pedicular screw. 3. C-D pedicular screw permitted early ambulation with minumum immobilization and slight loss of correction.
