- 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.

- STUDY DESIGN: Seventy femoral neck fractures in the elderly patients aged over 60 years treated with osteosynthesis or primary biploar arthroplasty were assessed on complication and functional outcome at final follow up.
OBJECTIVE: To compare the results of femoral neck fractures in the elderly patients aged over 60 years treated with osteosynthesis or primary bipolar arthroplasty retrospectively. To know the indications of each method.
SUMMARY OF BACKGROUND DATA: Althrough the osteosynthesis method had preservation of hip joint, primary osteosynthesis method had possibility of major complications as nonunion and avascular necrosis of femoral head.
METHODS
Seventy patients with intra-articular femoral neck fracture were treated with osteosynthesis in 33 patients(group 1) and primary biploar arthroplasty in 37 patients(group 2). A comparartive analysis of age, sex, type of fracture, initial displacement of fracture, method of treatment, fixation device type, quality of reduction, operative time, blood loss at operation, complication and functional outcome at final follow up were performed.
RESULTS
The female was more three times than male. The mean ages were 70.1 years old in group 1 and 73.3 years old in group 2. In group 1, complications such as non-union and avascular necrosis of femoral head were significantly greater in the subcapital fractures and Garden's stage 3,4 than the transcapital fractures and Garden's stage 1,2. In operative method, blood loss and operative time were significantly greater in the group 2 than in the group 1. Seven major complications (avascular necrosis: 6 cases, non-union: 1 case) occurred in group 1, two major complications(death: 2 cases) occurred in group 2. The functional outcomes were superior to the group 2, but it may be due to high complication rates in group 1.
CONCLUSIONS
This study suggests that the important factors that influenced the clinical results were type of fracture, initial displacement of fracture, quality of reduction. So in relatively poor arthroplasty.
