A randomized study was performed on 110 patients who had Austin Moore replacement of femoral head from January 1988 to December 1989 and followed up for 18 months.
All patients with intracapsular fracture neck for femur (age more than 60 years) with late presentation and Garden III and IV with early presentation, failed osteosynthesis, other fixation devises and avascular necrosis of the head of femur were included in the study.
Posterior exposure was performed on 67 (60.9%) patients while anterolateral exposure on 43 (39.1%) patients.
The rate of dislocation and subluxation in posterior exposure was 1 case (0.9%) and in anterolateral exposure was 4 cases (3.6%).
The rate of infection in posterior exposure was 5 cases (4.5%) while in anterolateral exposure was 12 cases (10.8%).
The fracture of femur which occurred during the operation was 2 cases (1.8%) and late fracture noted was 2 cases (1.8%) in the anterolateral exposure group, while no such complication was noted in the posterior exposure group.
