Dellon decompression of the tarsal tunnel: An effective approach to improving blood flow, promoting ulcer healing and recovery of sensibility in diabetic patients.

We hypothesized that tibial nerve decompression would improve sympathetic nerve function, leading to increased blood flow, enhanced plantar sensitivity, and reduced healing time for diabetic neuropathic ulcers. This prospective study involved 20 patients with non-healing diabetic neuropathic ulcers averaging 17.1 months in duration.
