详细说明
Diabetes patients with a recently healed, non-ischemic plantar diabetic foot ulcer will be randomized to "best care" standard post-ulcer treatment or to best care plus bilateral nerve decompression by external neurolysis at 4 fibro-osseous tunnel sites in the leg and foot. Comparison of the control group with standard care to the surgical intervention group will be made for subsequent appearance of a plantar foot ulcer and ulcer recurrence risks will be calculated. Additional subjective and objective secondary outcomes will be monitored. Null hypothesis: nerve decompression will not decrease diabetic foot ulcer recurrence risk.
If protection against ulcer occurrence were to be confirmed, a change in the treatment paradigm for diabetic neuropathy and foot ulcer could be appropriate.
