INCIDENCE OF POSTERIOR DISLOCATION OF HIP IN POSTEROLATERAL (MOORE) APPROACH VS ANTEROLATERAL (HARDINGE) APPROACH IN HIP ARTHROPLASTY AFTER FRACTURE NECK OF FEMUR

Objective: To compare the incidence of posterior dislocation of hip joint in Moore and Hardinge approach in hip arthoplasty for the treatment of fracture neck of femur during 12 weeks follow-up after surgery Materials & Methods: This multicenter randomized controlled was conducted at Department of Orthopedic Surgery, Bahawal Victoria Hospital, Bahawalpur, Civil Hospital Bahawalpur and Shahid Surgical Hospital Bahawalpur from July 2016 To July 2019. A total of 300 patients, 65 to 85 years of age with Garden type IV fracture of neck of femur were included in the study. Patients were divided into two age groups A (Moore approach) & B (Hardinge approach) randomly. Posterior Dislocation of hip joint was compared between the both groups. Results: In present study, mean age of patients was 78.59 ± 4.48 years. The mean age of patients in group A was 79.92 ± 4.38 years and in group B was 78.58 ± 5.27 years. In study group A, posterior dislocation was found in 15 (10%) patients while in study group B posterior dislocation was found in 4 (2.67%) patients. Significantly (P = 0.013) higher posterior dislocation was found in study group A as compared to study group B. Conclusion: This study concluded that incidence of posterior dislocation of hip joint was less after Hardinge approach compared to Moore approach in hip arthoplasty for the treatment of fracture neck of femur.
