Effect of co-morbidities on outcomes of first metatarsophalangeal joint fusion: A systematic review.

Introduction: The pre-existing co-morbidities have a major impact on the outcomes of Orthopaedic procedures as shown by the several studied in various contexts. However, the specific influence of these co-morbidities on first metatarsophalangeal joint fusion remains relatively underexplored. This study aims to address this gap by examining the association between co-morbidities such as obesity, smoking, diabetes, advancing age, and rheumatoid arthritis, and the outcomes of first metatarsophalangeal joint fusion.
