Surgical Offloading Techniques Should be Used More Often and Earlier in Treating Forefoot Diabetic Ulcers: An Evidence-Based Review

Conservative treatment is the basis for diabetic foot ulcer (DFU) management, whereas surgical treatment is usually reserved for patients with failed, recurrent, or nonresponsive infected wounds. However, many reports demonstrated good to excellent results following surgery. Evidence synthesis on surgical offloading techniques and clear guidelines regarding the timing of surgery are lacking. The present study aimed to investigate the evidence behind surgical offloading techniques and propose a cutoff time for surgical indication following failed conservative treatment of neuropathic diabetic forefoot ulcers. Electronic databases were searched from inception to identify the best evidence level articles related to non-vascular surgical treatment of DFUs, such as metatarsal head resection, resection arthroplasty, metatarsal osteotomy, Achilles tendon lengthening, gastrocnemius recession, and flexor tenotomy, that have been employed for managing DFUs. Based on the highest level of evidence available, surgery was found to generate better values than standard conservative care for all outcomes except for the transfer rate. In particular, surgical bony offloading procedures demonstrated significantly better outcomes than standard conservative nonsurgical care in terms of higher healing rates, shorter healing durations, and lower recurrence rates. Moreover, 96% of DFUs healed in <1 month following surgical bony offloading, whereas 68% of ulcers healed within 3 months after standard care. The findings could challenge the classical guidelines of DFU management. This evidence-based review indicates that surgical offloading could be used more often and be proposed earlier during the course of ulcer management. The results imply that a period of 12 weeks could be considered a reasonable cutoff value to consider surgical treatment for patients with nonhealing DFUs.
