The authors have reviewed 47 cases of the elderly patients beyond 60 years of age with displaced fractures of the femur neck which were treated with internal fixations from September, 1983 to September, 1990. Follow-up period for these cases was more than 1 year. The results were obtained as follows:1. The cases were consisted bf 12 male patients(26.5%) and 35 female patients(73.5%). 2. 27 cases(57,4%) were of Garden stage III and 20(42.6%) were of Garden stage IV. The most common anatomical site of fracture was transcervical with 2.5 cases(53.2%). 3. The singh's index for osteoporosis:Grade IV in 21 cases(44.8%), Grade III in 16(34.0%), Grade II and III in 5(10.6%) respectively in order of frequency. 4. The average interval from injury to operation was 36 hours ranging from 4hours to 12 days. 5. The methods of internal fixation were compression hip screw in 25 cases(53.2%), multiple pinning in 17(36.2), and compression hip screw with additional pinning in 5(10.6%). 6. The functional results were as follows:excellent in 12 cases, good in 19 cases, fair in 9 cases and poor in 5 cases. 7. The complications were in 13 cases(27.7%):avascular necrosis in 5(10.6%), nonunion in 4(8.5%), death in 2(4.3%), 1 case(2.1%) of fixation loss and 1 case(2.1%) af infection. With above results, we can conclude that good result out of the displaced femur neck fractures in elderly patients was obtained by early anatomic reduction and internal fixation using compression hip screw followed by early ambulation.
