We studied the influence of different positions in neighboring joints on strain in the tibial and plantar nerves during ankle and toe movements. Tibial nerve strain at the ankle was measured during ankle dorsiflexion in ten cadavers; plantar nerve strain was measured during toe extension. Tibial nerve strain increased with ankle dorsiflexion (mean increase: 3.9%) and strain was higher when the ...

1. Two aspects of nerve-muscle development were studied in neonatal rats, the role of competition between motor neurones during the elimination of polyneuronal innervation, and the dependence of muscle fibre production upon the number of motor neurones innervating the muscle. 2. Rat lumbrical muscles were partially denervated at birth by cutting the lateral plantar nerve. Many muscles remained ...

The ankle block is a safe and effective means of providing sensory anesthesia to the foot. The nerve supply to the foot at the level of the ankle is relatively superficial and consists of five nerve branches. The posterior tibial, which supplies the plantar aspect of the foot; the saphenous, supplying the medial portion of the foot; the deep peroneal, supplying an area between the great and sec...

The clinical significance of the ramus communicans, which connects the medial and lateral palmar/plantar nerves, should be determined to avoid errors in interpreting the effects of diagnostic anesthesia of the palmar/plantar nerves of horses during lameness examination. To determine its clinical significance, the ramus communicans of the pelvic limbs of 2 ponies was transected. Two months later...

Labat's classic approach to the sciatic nerve has not been able to show which motor response of the foot provides a more frequent rate of complete sensory and motor block. In this prospective, randomized, double-blind study, we compared plantar flexion with dorsiflexion with regard to onset time and efficacy of sciatic nerve block using the classic posterior approach. A total of 80 patients und...

The authors measured the thickness of the medial, central, and lateral bands of the plantar fascia using ultrasonographic techniques in 109 symptomatic patients with 211 painful heels. Plantar fasciitis was diagnosed by the presence of plantar heel pain and tenderness of the plantar fascia on palpation and was correlated with plantar fascia thickness. All of the symptomatic feet had medial band...

BACKGROUND Both vascular and compression etiologies have been proposed as the source of neurologic symptoms in tarsal tunnel syndrome. Advancing the understanding of the arterial anatomy supplying the posterior tibial nerve (PTN) and its branches may provide insight into the cause of tarsal tunnel symptoms. The purpose of this study was to describe the arterial anatomy of the PTN and its branch...
