Objectives: Delayed wound healing is one of the most common complications following forefoot surgery in patients with rheumatoid arthritis. We aimed to identify the risk factors for delayed wound healing following rheumatoid forefoot surgery. Methods: Consecutive patients who underwent primary rheumatoid forefoot surgery (86 feet; 53 patients) between April 2008 and February 2019 were retrospectively evaluated. Clinical data, including smoking history, duration of the disease, presence of diabetes mellitus, medication, white blood cell count, erythrocyte sedimentation rate (ESR), C-reactive protein, the surgical procedure performed, and the Japanese Society for Surgery of the Foot (JSSF) scores, were collected. Results: Delayed wound healing was identified in 20 of 86 (23.3%) feet. In univariate analysis, participants showing delayed healing were older at the time of surgery (p =.04), their ESR was higher (p =.0006), and their total (p =.019) and pain (p =.016) scores on the JSSF Lesser toe scale were lower than those showing normal healing. In multivariable analysis, both the total preoperative JSSF Lesser toe scale score (p =.0239) and ESR (p =.0126) remained significant risk factors for delayed wound healing. Conclusions: After rheumatoid forefoot surgery, surgeons should pay more attention to wound care in patients with lower preoperative JSSF Lesser toe score and high ESR.
