Biosynthetic nerve grafts are developed in order to complement or replace autologous nerve grafts for peripheral nerve reconstruction. Artificial nerve guides currently approved for clinical use are not widely applied in reconstructive surgery as they still have limitations especially when it comes to critical distance repair. Here we report a comprehensive analysis of fine-tuned chitosan nerve guides (CNGs) enhanced by introduction of a longitudinal chitosan film to reconstruct critical length 15 mm sciatic nerve defects in adult healthy Wistar or diabetic Goto-Kakizaki rats...

A randomized, double-blind, three-period cross-over study was performed to characterize the sensory phenotype and pain demographics in patients with Morton neuroma (n=27) and to explore the effects of local administration (2mL) of placebo and lidocaine (1 and 10mg/mL) around the neuroma. Using the pain quality assessment scale (PQAS), the highest rating was seen for unpleasant pain and intensity of deep pain and the lowest for sensitive skin. Ongoing pain was reported in 32% of patients. Patients reported mild to moderate average pain, and that pain had interfered with sleep only marginally...

Morton's neuroma is a common pathologic entity that, traditionally, was considered to be an isolated tumor that rarely affected more than 1 interdigital space. However, in recent years, multiple neuromas have become more common in our day-to-day practice. The objective of the present study was to assess the frequency with which Morton's neuroma appears in the different interdigital spaces. A retrospective study was performed of 279 feet that had been surgically treated for Morton's neuroma using a dorsal approach during a 9-year period (from January 2003 to December 2011), with an ultrasound scan taken preoperatively and histopathologic analysis performed afterward...

INTRODUCTION: "Morton neuroma" is a common cause of forefoot pain with numbness frequently occurring in the distribution of the third common digital nerve. After the failure of nonoperative measures, decompression with excision of the neuroma is common practice. Residual numbness and recurrent pain has been reported as a consequence of this treatment option. This study describes excision of the neuroma with interpositional nerve grafting as a treatment option for Morton neuroma. This proposed technique has the benefit of reducing pain, reducing recurrent secondary neuromas and restoring postexcision sensory deficits...

Intermetatarsal neuroma or Morton's neuroma is a painful condition of the foot resulting from an entrapment of the common digital nerve typically in the third intermetatarsal space. The pain can be severe and especially problematic with walking. Treatment options are limited and surgery may lead to permanent numbness in the toes. Capsaicin, the pungent ingredient of hot peppers, produces analgesia by inducing retraction of nociceptive afferents from the area of innervation and is effective in treating certain neuropathic pain disorders...

The common peroneal nerve arises from the sciatic nerve and is subject to a variety of abnormalities. Although diagnosis is often is based on the clinical findings and electrodiagnostic tests, high-resolution sonography has an increasing role in determining the type and location of common peroneal nerve abnormalities and other peripheral nerve disorders. This article reviews the normal sonographic appearance of the common peroneal nerve and the findings in 21 patients with foot drop related to common peroneal neuropathy...

BACKGROUND: The deep peroneal nerve innervates muscles of the anterior leg compartment and the dorsum of the foot, and also receives sensation from the first interdigital cleft of the foot. Along its course in lower part of the leg, this nerve is very close to the anterolateral surface of the tibia and might be vulnerable to injury in fractures of the tibia or during surgery. OBJECTIVE: The objective of this study is to clarify the relationship between the deep peroneal nerve and anterolateral surface of tibia...

OBJECTIVE: Peroneal nerve entrapment neuropathy (PEN) is generally known as a drop foot with sensory disturbance. However, some patients experience numbness and pain in the affected area without severe paresis due to PEN. We report the clinical features and our surgical results of PEN cases. METHODS: We encountered 17 cases of PEN. The patients were 7 females and 10 males and their ages ranged from 30 to 78 years(average 56.1 years). In these cases, conservative therapy was unsuccessful;therefore, we performed surgical treatment for PEN...

AIM: Aim of the study was to examine the effects of the geko™ device (a portable electical nerve stimulator) on microcirculatory flow on the dorsum of the foot, and whether this is influenced by lower limb postures and application of a plaster cast. METHODS: This was a cross-sectional, healthy cohort, open label, physiological response study. In 10 healthy volunteers, aged 19 to 24 years, laser Doppler fluxmetry measurements were made on the dorsum of the foot in four postures: standing (weight bearing and non-weight bearing) and supine lying (with the lower limb horizontal and then elevated)...

BACKGROUND: Among the various operative treatments of Morton's neuroma, deep transverse metatarsal ligament (DTML) release has been performed for decompression of neuroma. However, the main lesion of Morton's neuroma is located between the metatarsal head and the metatarsophalangeal (MTP) joint and more distal than the DTML. Hence we performed the metatarsal shortening osteotomy along with DTML release for decompression of neuroma, and investigated the clinical outcomes of it and compared the outcomes with those of DTML release alone...

Transplantation of motoneurons (MN) into the peripheral nerve to provide a source of neurons for muscle reinnervation, termed motoneuron integrated striated muscle (MISM), may provide the potential to restore functional muscle activity, when combined with computer-programmed functional electrical stimulation (FES). The number of MNs required to restore innervation to denervated muscles in adult Fischer 344 rats was investigated by comparing two groups, one transplanted with 2 × 10(5) cells (group A) and the other with 1 × 10(6) cells (group B)...

Peripheral nerves traverse through different soft tissue compartments in the upper and lower extremities via specific anatomical tunnels, where they are susceptible to entrapment. Common sites in the upper extremity include carpal tunnel, cubital tunnel and radial tunnel. Common sites in the lower extremity include piriformis, fibular neck, and tarsal tunnel. Compressive peripheral neuropathy can develop in these sites, and are amenable for surgical decompression.

OBJECTIVE: To demonstrate the bifurcation pattern of the tibial nerve and its branches. METHODS: Eleven legs of seven fresh cadavers were dissected. The reference line for the bifurcation point of tibial nerve branches was an imaginary horizontal line passing the tip of the medial malleolus. The distances between the reference line and the bifurcation points were measured. The bifurcation branching patterns were categorized as type I, the pattern in which the medial calcaneal nerve (MCN) branched most proximally; type II, the pattern in which the three branches occurred at the same point; and type III, in which MCN branched most distally...

Tarsal tunnel syndrome, a compressive neuropathy of the tibial nerve or its branches with in the tarsal tunnel, is an uncommon condition. Various etiologies of the syndrome have been described. We report a rare case of tarsal tunnel syndrome associated with a perforating branch from the posterior tibial artery. A 56-year-old woman presented with 1-year history of paresthesia and hypoesthesia in the medial and lateral plantar area of the left foot. Tinel's sign was elicited at the tarsal tunnel. Electrodiagnostic studies confirmed the diagnosis of left tarsal tunnel syndrome...

Surgical correction of hindfoot varus is frequently performed with a lateral displacement calcaneal osteotomy. It has rarely been associated with iatrogenic tarsal tunnel syndrome in patients with pre-existing neurological disease. We report the first case of acute postoperative tarsal tunnel syndrome in a neurologically intact patient with post-traumatic hindfoot varus. Early diagnosis and emergent operative release afforded an excellent clinical outcome. Imaging studies can help outrule a compressive hematoma and assess for possible nerve transection; however it is paramount that a high index of suspicion is utilized with judicious operative intervention to minimize long-term sequelae...

BACKGROUND: According to recent studies, peripheral nerve decompression in diabetic patients seems to not only improve nerve function, but also to increase microcirculation; thus decreasing the incidence of diabetic foot wounds and amputations. However, while the postoperative improvement of nerve function is demonstrated, the changes in peripheral microcirculation have not been demonstrated yet. The aim of this study is to assess the degree of microcirculation improvement of foot after the tarsal tunnel release in the diabetic patients by using transcutaneous oximetry...
