1. Reinnervation of adult rat fourth deep lumbrical muscles was studied, following extensive partial denervation of the hindfoot by crushing the lateral plantar nerve (LPN). Most muscles remained innervated by between one and five motor axons supplied by the sural nerve (SN). Intact SN motor units expanded as a result of collateral sprouting. Virtually complete collateral reinnervation occurred...

We compared patterns of intraepidermal nerve fibers and mechanoreceptors from affected and unaffected plantar skin from patients with pachyonychia congenita (PC) and control subjects. Plantar biopsies from 10 genetically confirmed patients with PC (with a mutation in KRT6A) were performed at the ball of the foot (affected skin) and the arch (unaffected) and were compared to biopsies from corres...

Recognizing the arterial variations of human upper extremities is of potential clinical practice because this area is involved in arterial handling and invasive medical procedure. During dissection of the left upper limb of a 35-year-old male embalmed cadaver, we saw brachial artery bifurcation in the middle third of proximal portion of the arm. Its medial branch descended along the medial side...

An experimental crush injury to the sciatic nerve, with a crush force of 49.2 N (pressure p=1.98x10(8) Pa), was inflicted in 30 male rats (Wistar). A control group (sham), with the same number of rats, was also operated upon exactly as the experimental group but without the crush injury. We tested the sensory and motor recovery of the sciatic nerve with Hargreaves method, using an apparatus fro...

INTRODUCTION Although ganglion cysts are common soft tissue tumors, nerve compression syndrome caused by a ganglion cyst in the lower extremities is very rare. Herein, we report a 57-year-old man who presented with hypoesthesia in the sole of his right foot for 6 months. We believe that reporting this rare case will help clinicians update their knowledge on possible causes of the plantar neurop...

BACKGROUND Radiofrequency (RF) treatment is a minimally invasive procedure that has been used for more than 3 decades in treating various chronic pain syndromes. Conventional (continuous) RF treatment occasionally results in worsening or even initiating a new type of pain. The use of pulsed radiofrequency (PRF), which has a non- or minimally neurodestructive neuromodulatory effect, serves as an...

CONTEXT Taping and orthoses are frequently applied to control excessive foot pronation to treat or prevent musculoskeletal pain and injury of the lower limb. The mechanism(s) by which these devices bring about their clinical effects are at best speculative and require systematic evaluation. OBJECTIVE To determine the initial effect of the augmented low Dye taping technique (ALD) on plantar fo...

Absence of the right lateral rectus muscle and hypoplasia of the left was found in a child with congenital esotropia. He had mental and physical retardation, bilateral optic nerve hypoplasia, and many minor dysmorphic features, including brachycephaly, high forehead, poorly folded, low set ears, epicanthic folds, exaggerated Cupid's bow, long philtrum, and single palmar creases. Unusual feature...

We present a rare case of traumatic lesion the tibial fibers sciatic nerve with spared peroneal fibers. A 33-year-old victim three month earlier stabbing attack came to our attention gait impairment and weakened left foot plantar flexion internal rotation supination. Based upon clinical signs neurophysiological investigations we suspected that injury had occurred. Ultrasound examination detecte...
