“…At least six studies have confirmed ND can provide significant, although not total protection against DFU and recurrence [17,21–25]. Studies also exist using as outcomes perineural tissue pressure [18], transcutaneous oxygen pressures [37], and measured balance [56,72]. …”

Nerve decompression and neuropathy complications in diabetes: Are attitudes discordant with evidence?

External neurolysis of the nerve at fibro-osseous tunnels has been proprosed to treat or prevent signs, symptoms, and complications in the lower extremity of diabetes patients with sensorimotor polyneuropathy. Nerve decompression is justified in the presence of symptomatic compressed nerves in the several fibro-osseous tunnels of the extremities, which are known to be frequent in diabetes. Quite a body of literature has accumulated reporting results after such nerve decompression in the leg, describing pain relief and sensibility improvement, as well as balance recovery, diabetic foot ulcer prevention, curtailed ulcer recurrence risk, and amputation avoidance.Historical academic hesitance to endorse surgical treatments for pain and numbness in diabetes was based primarily on the early retrospective reports’ potential for bias and placebo effects, and that the hypothetical basis for surgery lies outside the traditional etiology paradigm of length-dependent axonopathy. This reticence is here critiqued in view of recent studies using objective, measured outcome protocols which nullify such potential confounders. Pain relief is now confirmed with Level 1 studies, and Level 2 prospective information suggests protection from initial diabetic foot ulceration and most neuropathic ulcer recurrences. In view of the potential for nerve decompression to be useful in addressing some of the more difficult, expensive, and life altering complications of diabetic neuropathy, this secondary compression thesis and operative treatment methodology may deserve reassessment.

“…Ducic and coauthors 41 reported bilateral ND improves balance as measured by sway, and Rosson and coauthors 35 found perineural tunnel pressures, so high as to threaten tissue survival, returned to safe levels after ND. In 75 DSPN legs with prior ulcer, of IWGDF group 3, after ND, ipsilateral DFU recurrence risk is >80% reduced from historical values.…”

“…2,30,31 Objective outcome studies and prospective or randomized controlled trial protocols now report beneficial ND effects on balance, tunnel tissue pressures, ulceration risk, DFU recurrence risk, and electrophysiological parameters, as Figure 2 shows. [32][33][34][35][36][37][38][39] These often include and correlate common subjective measures of DSPN symptoms and signs. Aszmann and coauthors 32 first published the unanticipated finding that every ulceration and amputation in 50 DSPN cases that had unilateral ND surgeries for leg pain occurred in the contralateral, nonoperated legs.…”

Reconsidering Nerve Decompression: An Overlooked Opportunity to Limit Diabetic Foot Ulcer Recurrence and Amputation

Nerve decompression for relief of subjective diabetic sensorimotor polyneuropathy pain and numbness has been labeled of "unknown" benefit. Objective outcomes in treatment and prevention of diabetic foot complications are reviewed. There is growing evidence that plantar foot ulceration and recurrence in high-risk feet are minimized with this operation. Avoiding neuropathic and neuroischemic ulcer wounds should theoretically reduce amputations and perhaps mortality risk. Protective effects are hypothesized to act via relief of neurovascular entrapment, thereby improving neurally modulated tissue homeostasis factors. Nerve decompression deserves considerable research attention to understand its role in limiting foot complications. Its apparent benefits challenge the paradigm that diabetic neuropathy is a purely length-dependent axonopathy and may necessitate appreciation of superimposed nerve entrapment as an significant operant factor.

“…Using a graded compression, it was noted that at pressures of 20-30 mmHg, axonal transport was blocked. According to Rosson et al, 40 perineural tissue pressures of 26 mmHg are recorded in diabetes patients with focal nerve entrapment in the foot. Additional work by Dahlin and McLean 41 in a rabbit model reported similar effects in both slow and fast axonal transport.…”

The most recent (2011) National Diabetes Fact Sheet states the tally of diagnosed and undiagnosed diabetes cases in the United States is approaching 25 million, and another 79 million are prediabetic. Of the diabetes patients, 60-70% suffer from mild to severe neuropathy.1 This combined loss of sensory and motor control in diabetic limbs is usually considered an irreversible, progressive process. Patients suffering from these losses are at significantly higher risk for development of foot ulceration, frequently leading to infection, and minor or major limb amputation. 2-8However, a review of surgical decompression literature addressing focal nerve entrapment suggests that several diabetic sensorimotor polyneuropathy (DSPN) symptoms and complications are potentially partially reversible or preventable. The following review surveys current research regarding the biological basis for diabetic focal entrapment neuropathy, observational studies correlated to that biological basis, and the clinical rationale and outcomes related to nerve decompression (ND) surgery. BackgroundIt is important to note that diabetic neuropathies are heterogeneous disorders. This discussion is focused on the somatic subset described as distal symmetric peripheral polyneuropathy, classically known as "stocking-glove anesthesia." Determinants affecting the rate of development and ultimate severity of the neuropathy include: duration of diabetes and adequacy of glucose control, 9 a conclusion morphologically confirmed by Perkins et al. 10 Two separate types of focal neuropathies are recognized: mononeuropathies and entrapment.11 Mononeuropathies are felt to be the consequence of vascular injury, and are said to resolve with only supportive care management. Entrapment neuropathies (the focus of this discussion) are said to occur in up to 30% of all diabetic neuropathy 12 and are postulated to occur as the result of a "double crush" phenomena. AbstractThe most recent (2011) National Diabetes Fact Sheet states the combined diagnosed and undiagnosed number of diabetes cases in the United States is approaching 25 million, and another 79 million are prediabetic.

However, a review of focal nerve entrapment surgical decompression literature suggests that several diabetic sensorimotor polyneuropathy (DSPN) symptoms and complications are potentially partially reversible or preventable. Decompression surgery represents a paradigm shift in treatment protocols because it both relieves pain and restores protective sensation, while providing significant protection against a cascade of serious foot complications. This review surveys current research regarding the biological basis for...
