Débridement and primary closure of nonhealing foot wounds.

Fifty-eight chronic nonhealing foot wounds (51 patients) were treated with irrigation, aggressive débridement, and primary tension-free closure. Factors such as wound location, wound size, presence of infection, and healing outcome were recorded. In addition, medical comorbidities and preoperative laboratory test results were reviewed. Thirty-seven (64%) of the 58 wounds healed after primary closure. Of the other 21 wounds, 16 healed after repeat irrigation, debridement, and closure or local wound care; 2 patients were lost to follow-up after initial failed wound healing, 1 patient died after initial failed wound healing, and 2 cases were salvaged with amputation. Failed primary closures were thought not to increase wound size; all but 3 of these closures decreased wound size significantly. Differences between the wounds that healed primarily and the wounds that failed healing were not statistically significant. Diabetes was present in 46% of the patients whose wounds healed primarily versus 71% of the patients whose wounds failed healing (P = .06). Irrigation, débridement, and primary closure of nonhealing foot wounds can be a useful treatment option for most such patients. Complete healing or reduced wound size occurs in 95% of cases.
