: The purpose of this study was to describe the relationship between balance and foot sensibility in a population of patients with impaired lower extremity sensation. The hypothesis was that increasing impairment of sensation correlates with impaired balance. To date, no report has investigated the relationship between loss of balance with the degree of sensibility in the foot in a population with neuropathy. Ten control subjects and 35 patients with sensory abnormalities and balance ...

PURPOSE: To describe a neuroma of the posterior cutaneous nerve of the forearm that can be the source of pain after surgery for lateral humeral epicondylitis.

METHODS: A retrospective chart review of 9 patients having pain after surgery for lateral humeral epicondylitis was conducted to evaluate their history of pain, surgical findings during exploration of their painful lateral elbow scar, and outcome of their surgical treatment.

RESULTS: In each of the 9 patients a neuroma of the ...

BACKGROUND: The neuropathic groin pain after inguinal hernia repair is usually due to a neuroma of the ilioinguinal, iliohypogastric, or genitofemoral nerve. When the postherniorrhaphy pain symptoms include mostly testicular pain, then the genital branch of the genitofemoral nerve comes first in the differential diagnosis. Nerve blocks are helpful in determining which of the three nerves is implicated in the pain syndrome. Although the surgical approach to the ilioinguinal nerve is now ...

BACKGROUND: Pressure in the tarsal tunnel has been shown to be elevated when the ankle is pronated. We hypothesized that this also would be true for the medial plantar and lateral plantar tunnels because they also are potential sites of nerve compression. Additionally, we hypothesized that decompression surgery, including a release of the superficial and deep fascia of the abductor hallucis muscle and excision of the septum between the medial and lateral plantar tunnels, would decrease ...

BACKGROUND: Some sensation to the breast returns after breast reconstruction, but recovery is variable and unpredictable. We primarily sought to assess the impact of different types of breast reconstruction [deep inferior epigastric artery perforator (DIEP) flaps versus implants] and radiation therapy on the return of sensation.

METHODS: Thirty-seven patients who had unilateral or bilateral breast reconstruction via a DIEP flap or implant-based reconstruction, with or without radiation ...

BACKGROUND: The anatomical basis for the surgical techniques used to treat tarsal tunnel syndrome is not well studied. The authors sought to evaluate their hypotheses that (1) pronation and pronation with plantar flexion of the intact foot would have higher pressures than the intact foot in other positions; (2) decompression surgery would significantly lower the pressure in all three tunnels in all foot positions, and roof incision plus septum excision would lower the pressure further in ...

This was an initial exploratory study to determine if decompression of the 4 medial ankle tunnels (neurolysis of the tibial, medial and lateral plantar, and calcaneal nerves) could lead to improved foot sensibility, increased proprioception and balance, and decreased falls in a population of patients with impaired lower extremity sensation. Fourteen patients with peripheral neuropathy were included in this study. Seventy-one percent of patients were females. Average age was 67 years. All ...

During the past 12 years, 6 studies reported restoration of sensation and relief of pain in the foot by decompression of the tibial nerve and its distal branches in diabetic neuropathy. Although a positive Tinel sign related to favorable outcomes in some of the reports, this relationship was not evaluated specifically. In this study, the presence of the Tinel sign, positive or negative, over the tibial nerve was recorded in 46 patients with diabetic neuropathy and in 40 patients with ...

Despite the high percentage of patients who are satisfied completely with the results of total knee arthroplasty, there is a small group who remain disabled because of persistent neuroma pain. Recently, a better understanding of the innervation of the skin and capsule around the human knee joint has provided a theoretical basis for denervation in this group of patients. Fifteen patients were identified who had persistent or worse knee pain for > 6 months after total knee arthroplasty. In ...

BACKGROUND: In the absence of a randomized, prospective study comparing different surgical approaches for decompression of the ulnar nerve at the elbow, the choice of an approach relies on the individual surgeon's training and experience. The present report describes the results of a prospective, long-term evaluation of the musculofascial lengthening technique in a large series of patients. In these patients, the degree of ulnar nerve compression was staged with use of a numerical ...

Intraneural ganglia are rare entities, and, as such, their pathogenesis has been extremely controversial. Recent evidence from intraneural ganglia occurring at more proximal sites-the peroneal nerve at the fibular neck (the most common site) and the tibial nerve at the knee-has suggested an articular origin rather than de novo formation. To our knowledge, of the 10 previous reports of tibial intraneural ganglia within the tarsal tunnel by others, a joint connection to the ankle joint was ...

Entrapment of the superficial peroneal nerve is an uncommon entrapment that occurs in sports trauma or fracture and dislocation as the nerve comes under pressure between the underlying muscles and the overlying fascia. Although the superficial peroneal nerve traditionally is depicted as being in the lateral compartment, we have found it in the anterior compartment in some patients. We hypothesized that patients with entrapment of the superficial peroneal nerve were more likely to have ...

A prospective study was done to evaluate the results of treating recurrent "Morton's" neuroma by a technique that combined resecting the interdigital neuroma through a plantar approach and implantation of the proximal end of the nerve into an intrinsic muscle in the arch of the foot. As a part of this study, quantitative sensory testing was done for the medial plantar and medial calcaneal nerves. Seventeen recurrent interdigital neuromas were resected in 13 patients. Pain was identified ...
