Abstract
Background: To investigate wound healing in 402 calcaneus fracture cases using precise extensive L-shaped incision.Method: We retrospectively analyzed 402 calcaneus fracture cases, involving patients who underwent heel bone reduction and internal fixation, using precise extensive L-shaped incision, at the second hospital of Shanxi medical university between January 2018 and December 2020. Postoperative would healing was evaluated using a self-designed skin margin grading system. Results: The patients experienced osseous healing after the surgery. A Maryland foot score of ≥90% was considered excellent. The skin margins from Grade I, II, III injuries healed spontaneously after dressing change. However, Grade IV injuries healed after debridement or removal of internal fixation.Conclusions: The precise extensive L-shaped incision, used in this study, allowed for fewer postoperative wound complications and lower incidence of skin necrosis.
