Nerve Decompression for Ulcer Recurrence Avoidance (DURA) (DURA)
A Prospective Study of Recurrence Risk in Diabetic Foot Ulceration After Nerve Decompression

Intervention / Traitement
Description détaillée
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.

Armes et Interventions
Groupe de participants / Bras |
Intervention / Traitement |
|---|---|
|
Comparateur placebo: healed DFU control arm
clinic-specific usual "best care"
|
|
|
Expérimental: healed DFU surgical intervention
clinic-specific "best care" plus nerve decompression at 4 known sites of lower leg fibro-osseous entrapment
|
surgical decompression involves surgical division or incision of perineural fibrous or fibro-osseous tunnel tissues which pinch, choke, compress or sharply deviate nerve trunks.
