Orthopaedic Implant Failure
Journal Title: Surgery & Case Studies: Open Access Journal - Year 2019, Vol 2, Issue 3
Abstract
Background: Implant failure refers to the inability of any medical implant to meet the claims of its manufacturer or the health care provider who installs it. Some implants tend to fail more than others depending on location, type of implant and age of patient. Other pathologies such as infection, trauma and pathologic fractures are additional risk factors. Objectives: To determine the pattern of orthopaedic implant failure and possible risk factors in a Nigerian tertiary hospital. Methodology: A retrospective hospital-based study carried out over 10 years (January 2007 to December 2017) in which case notes of patients who had implant surgeries done were reviewed to determine those who had implant failure, the possible cause, treatment offered and outcome. Results were collated and subsequently analysed. Results: Majority were females (60%) and mean age was 48yrs +/- 2.2. Most surgeries were in the lower limbs and Infection was the strongest single risk factor identified (40%). Revision surgery was carried out for all and majority (86.7%) were without bone grafts. However, all yielded satisfactory outcome. Conclusion: Implant failure occurs more in the lower limb surgeries and affects middle aged females more. Infection is a strong risk factor however there is no association between aetiology and gender. Bone grafting in revision surgery does not affect outcome. The components of implants need to be further evaluated to determine risk of failure.
