Current concepts: Subclinical dermatologic conditions that increase surgical site infection risk in hand surgery

Hand surgery, despite being a clean and elective surgery, excluding trauma, still poses challenges such as functional impairment, risk of healing, and infection recovery. Certain conditions, such as psoriasis or dermatitis, can trigger some serious instances of trauma. This narrative review aims to map how these conditions contribute to surgical-site infections (SSIs), delayed healing, scarring/contracture, and functional or aesthetic impairment. Additionally, we hope to propose practical, interdisciplinary recommendations for preoperative screening and perioperative management tailored to elective hand surgery. From this review, we saw an even bigger risk arises from the Koebner phenomenon. Specific disorders can exacerbate the risk of infection and poor wound healing, impacting functionality and even appearance. Despite efforts from various sources, a standard screening process in dermatology for patients undergoing hand surgery remains elusive. Therefore, future study on more effective collaboration and integrating preoperative procedures into hand surgery protocols holds the most promising prospect for addressing postoperative complications in dermatology, ultimately improving patient support.
