A Comparative Study of Primary Total Hiparthroplasty by Direct Lateral or Posterior Approaches With Respect to Functional Outcome

Abstract

Introduction: Most of the sudies focuses on the surgical advantages and disadvantages of the posterior and direct lateral approaches to THA, in addition to identifying the effects of these surgical approaches on global function describing post-operative gait and activities of daily living (ADLs), local function describing muscle strength around the hip and iatrogenic damage of soft tissue around hip Aims and Objectives: To compare functional outcome following primary total hip arthroplasty among geriatric patients between two surgical approaches - direct lateral and posterior approaches. Material And Methods: Descriptive follow up study with comparison between two groups of patients operated by direct lateral and posterior approach of THA to be conducted in DEPARTMENT OF ORTHOPAEDICS, JAGANNATH GUPTA INSTITUTE OF MEDICAL SCIENCES AND HOSPITAL, KOLKATA from 18 months. 54 patients were included in this study. Result: In Direct lateral Group, 9(33.3%) patients had AVN of femoral head, 13(48.1%) patients had displaced neck of femur fracture and 5(18.5%) patients had osteoarthritis of hip joint. In Posterior Group, 7(25.9%) patients had AVN of femoral head, 7(25.9%) patients had displaced neck of femur fracture and 13(48.1%) patients had osteoarthritis of hip joint. Association of Indication of operation vs group was not statistically signicant (p=0.0606). Conclusion: Month of follow-up was higher in Posterior approach compared to direct lateral approach which was statistically signicant.
