Abstract OBJECTIVE Data from three Louisiana State University Health Sciences Center (LSUHSC) publications were summarized for median, radial, and ulnar nerve injuries. METHODS Lesion types, repair techniques, and outcomes were compared for 1837 upper-extremity nerve lesions. RESULTS Sharp laceration injury repair outcomes at various levels for median and radial nerves were equally good (91% each) and better than those for the ulnar nerve (73%). Secondary suture and graft repair outcomes were better for the median nerve (78% and 68%, respectively) than for the radial nerve (69% and 67%, respec

Background: Nerve transfers have resulted in increased interest in the microanatomy of peripheral nerves. Herein, we expand our understanding of the internal anatomy of the digital nerve to the ulnar index and long fingers, the radial long and ring fingers, and the nerves to the second and third web spaces. Methods: The median nerve was dissected from the digital nerves to the antecubital fossa in 14 fresh upper extremities. The distance of proximal internal neurolysis of the fascicles to the second and third web space and proper digital nerves was measured relative to the radial styloid. Plex

Objectives: Radiologic technologists (RTs) are typically exposed to low doses of radiations for longer periods, which have a health risk over many organs and tissues. Resistant tissues like nerves have shown neuropathic changes due to acute high-dose radiation exposure in the form of radiation therapy but the effect of low-dose chronic radiation exposure over peripheral nerves in RTs has been studied scantily. Materials and Methods: Nerve conduction parameters were recorded from 30 RTs and 30 age- and sex-matched healthy individuals who were not exposed to radiation. Motor nerve conduction stu

The pattern of reorganization in area 3b of adult primates after median or ulnar nerve section suggests that somatic afferents from the dorsum of the hand, carried by the radial nerve, have preferential access to the cortical territories normally expressing glabrous inputs carried by the median and ulnar nerves. A likely mechanism underlying preferential access is preexisting, but silent, radial nerve inputs to the glabrous region of cortex. 2.

Abstract:

Cutaneous nerve entrapment plays an important role in neuropathic pain syndrome. Due to the advancement of ultrasound technology, the cutaneous nerves can be visualized by high-resolution ultrasound. As the cutaneous nerves course superficially in the subcutaneous layer, they are vulnerable to entrapment or collateral damage in traumatic insults. Scanning of the cutaneous nerves is challenging due to fewer anatomic landmarks for referencing. Therefore, the aim of the present article is to summarize the anatomy of the limb cutaneous nerves, to elaborate the scanning techniques, and also to disc

Methods From 1999 to 2007, out of 791 reconstructed nerves in 441 patients treated for brachial plexus injury, the authors performed 21 axillary and 2 musculocutaneous nerve sutures onto the median, ulnar, or radial nerves.

Abstract:

We dissected 30 cadaveric thumb interphalangeal joints to delineate the sensory nerve anatomy of its capsule. Four articular branches supplying the interphalangeal joint capsule of the thumb were found in all specimens. Ulnar and radial proper digital nerves provide one palmar capsular nerve branch on their respective sides. Of the two dorsal branches of the radial nerve at the dorsum of the thumb, we observed that each nerve provided one branch to the interphalangeal dorsal capsule. Our findings demonstrate a consistent pattern of innervation and may provide the anatomical basis to the treati

They differ from classical schwannomas in the long duration for this subtype of schwannoma to develop and also by demonstrating haemorrhagic and degenerative changes with nuclear atypia. It is because of these histologic hallmarks that they are frequently misdiagnosed as malignant tumours. They usually involve the major nerves of flexor surfaces in upper extremity such as the ulnar and median nerve but schwannomas of the radial nerve are a rare entity.

Branches of the PCBm innervating the scaphoid were typically found, but in no specimen did we find a ‘typical’ cutaneous branch of the ulnar nerve. According to our findings, standard incisions for open carpal tunnel release carry a significant risk of damaging branches of the PCBm or PCBu. The chance of injury to these sensory nerves can be minimized by using a short incision in the pro

Abstract:

Precise pre- and postoperative assessments are fundamental to recording the quality of recovery after ulnar nerve repair. Because of its imprecision, manual muscle testing is being replaced by dynamometry to measure grasping and key-pinch strengths. However, both grasping and key pinch are dependent not only on the ulnar nerve but also the median and radial nerves. We propose to measure strength using a new sort of pinch, called the ‘subterminal key pinch’. Strength was measured using a commercially available pinch meter.
