Functional Outcome of Austin Moore Prosthesis(AMP) versus Bipolar Prosthesis in fracture neck of femur.
Keywords:
Austin Moore Prosthesis, Bipolar Prosthesis, Harris Hip Score, hemiarthroplasty.Abstract
Objective: To determine the functional outcome of Austin Moore Prosthesis(AMP) Versus Bipolar hemiarthroplasty prosthesis in fracture neck of femur
Methods: This Prospective randomized controlled trial was conducted at the Department of Orthopedics, Ward-17, Jinnah postgraduate Medical Centre, Karachi, from January 2016 to December 2016. The patients included 60 years or older, having displaced intra capsular neck of femur fractures. Patients with co-morbids, arthritis and pathological fractures were excluded. Patients were randomly divided equally in 2 groups, each group operated upon using standard techniques for Austin Moore and Bipolar hemiarthroplasties respectively. Functional outcome was measured as very good, good, fair and poor using Harris Hip Score at monthly interval and at 6th months follow up visit.
Results: The total numbers patients were 148(74 in each group). Final functional outcome showed that, in Bipolar prosthesis 72 (97.3%) patients had satisfactory status while 2 (2.7%) patients had unsatisfactory status. In Austin Moore group 64 (86.5%) patients had satisfactory status while 10 (13.5%) had unsatisfactory status
Conclusion: Bipolar prosthesis had better functional outcome than Austin Moore hemiarthroplasty. We recommend this as a treatment of first choice in elderly patients with fracture neck of femur.
