Osseointegration in uncemented total hip arthroplasty: A study of 37 cases

Abstract

Introduction: Osseointegration is the ability of implants to establish mechanical and functional bond with bone without forming any connective tissue. Osseointegration is useful for clinical follow-up in many implants e.g. dental implants, hearing aids, spinal fusion implants, prosthesis. Endoprosthesis functions pain free when their anchoring components are firmly fixed to the osseous tissue. Total hip arthroplasty is a common procedure in many conditions that reduces pain and improves functions. Noncemented implants need precise preparation of implant bed and additional fixation device such as screws or projections that cut into the bone to achieve stability. The long term stability and function of joint replacement can be evaluated on the basis of outcomes. If improper osseointegration occurs then fibrinous tissue formed between bone and implant that cause weak and loose implant. Materials and Methods: This was an observational type of study where non-cemented total hip replacement done by different surgeons were included for follow-up. The follow-ups were done in US
