Total Hip Arthroplasty in Octogenarians: A Local Retrospective Case Series

Abstract

With improving healthcare, the number of Filipino octogenarians is increasing. Projected population of octogenarians as reported by the Philippine National Statistics Office will increase by 28% to 3,227,253 by year 2040 (from 2015: 912,817). This is a multicenter retrospective case series involving 24 patients (1 patient with surgery on 2 hips), with an average age at the time of surgery of 82 years old (range: 80-88 years old) who underwent total hip arthroplasty during the period 2007-2016. Indications for total hip arthroplasty included 12 cases of degenerative osteoarthritis, 8 cases of displaced femoral neck fractures, 4 cases of untreated femoral neck fractures, and 1 case of subtrochanteric fracture with hip arthritis. Of the 24 patients, 21 were females and 3 were males. Of the 25 hips, 19 were treated with cemented total hip, 5 with hybrid implants, and 1 with calcar replacing cemented femoral stem. Average follow-up was 36 months (range: 6-87 months). All patients were able to ambulate and return to premorbid function. There were no intraoperative or postoperative complications encountered. Revision rate was zero percent as of last follow-up. Clinical/functional results were assessed using the Harris Hip Scoring system. The results of this study affirm that primary total hip arthroplasty is a viable treatment option for active octogenarians with end-stage arthritis and hip fractures.
