Research proposal abstract:
This retrospective cohort study will analyse data from the Dutch Arthroplasty Register (LROI) to investigate the impact of body mass index (BMI) on the survival of upper extremity arthroplasty. The study will include adult patients who underwent shoulder, elbow, wrist, finger or thumb arthroplasty. A Cox proportional hazards model will be used to assess the relationship between BMI and prosthesis survival while considering other potential influencing factors such as age, smoking status, and comorbidities. This analysis aims to determine the specific impact of BMI on the survival of upper extremity (non-weight-bearing implants) implants and identify additional significant factors affecting prosthesis survival. Results from this analysis address a notable gap in orthopaedic research and may have implications for clinical practice and understanding of patient care strategies in orthopaedic surgery.
