1. A follow-up study was performed on 68 patients, 20 male and 48 female, whose femoral heads were surgically replaced by prosthesis. Those patients included 58 cases of fracture of the femoral head, 35 fresh and 23 old, seven cases of avascular necrosis, two cases of fracture-dislocation, and one case of coxarthrosis.2. The age of fracture cases at the time of operation ranged betwee 44 and 86 years, 66.5 years on the average, and the duration of follow-up was eight months to ten years and seven months, two years and ten months on the average.3. Results of the treatment revealed neither difference due to the types of the diseases nor difference between fresh and old fractures.4. Difference in surgical technique also did not give any influence to the result of the operation.5. Good result was obtained when bone cement was used, but the result was poor in those cases with acetabular protrusion and those in which the acetabulum was reamed.6. Considerable difficulty in daily activities was found in 34per cent of femoral neck fracture.7. Pain diminished gradually as the time elapsed in 61.7per cent of the patients, but no correlation was found between the pain and X-ray findings except in those with acetablar protrusion.
