At the wrist the ulnar nerve passes through a fibroosseous tunnel known as “Guyon’s canal” or “distal ulnar tunnel” [1]. The clinical importance of this tunnel is that it may become a site of ulnar nerve compression [1-8]. Variety of causes has been determined for such compression including trauma, lipoma, false aneurysm of the ulnar artery, ganglion cyst and rarely aberrant muscular slips [2,4...

Direct posterior and posterolateral portals are the standard portals used in posterior elbow arthroscopy. A posteromedial portal in the elbow is not recommended because of its proximity to the ulnar nerve. However, iatrogenic injuries to the ulnar nerve have been reported after elbow arthroscopy using the standard posterior portals, especially in posteromedial elbow joint pathologies. We presen...

Cubital tunnel syndrome refers to ulnar nerve compressive neuropathy and most commonly occurs at the level of the elbow. Surgical options include in situ decompression, decompression with anterior transposition of the ulnar nerve, and medial epicondylectomy with or without decompression. With the advancement of endoscopic surgery, techniques of endoscopic in situ decompression of the ulnar nerv...

OBJECTIVE The purpose of this study was to obtain data on interrater repeatability of the motor nerve conduction velocity (NCV) of the ulnar nerve of different segments, ulnar distal motor latency (DML), and compound muscle action potential (CMAP) amplitudes. DESIGN Twenty-four healthy volunteers were examined in consecutive order. Ulnar motor NCV of different segments, ulnar DML, and CMAP am...

OBJECTIVE Earlier studies have shown sonographic enlargement of the ulnar nerve in patients with Hansen's neuropathy. The present study was performed to determine whether sonography or electrophysiological studies can detect the specific site of ulnar nerve pathology in leprosy. METHODS Eighteen patients (thirty arms) with Hansen's disease and an ulnar neuropathy of whom 66% had borderline tu...

<p class="abstract">Ulnar nerve dislocation is defined as abnormal movement of the ulnar at elbow joint. This has been reported in 16% asymptomatic arms. However, posttraumatic subluxation remains a rare clinical entity. We present unique case and describe characteristics etiology this injury how it was managed.</p>

ABSTRACT BACKGROUND Although fractures of the distal radius are a common clinical presentation, many factors affect instability of these injuries. The aim of this study was to assess the influence of age, sex, distal radial ulnar joint injury (DRUJ), ulnar styloid fracture, and dorsal displacement in late collapse of distal radius fractures. METHODS Three hundred twenty-nine patient fractu...

Background Few reports describe the distribution of cutaneous perforators from the radial and ulnar arteries in the forearm. This study aimed to map the location of the cutaneous perforators that arise directly from the radial and ulnar arteries in cadavers. Methods Twenty-nine human cadaveric forearms were dissected. All radial and ulnar arteries cutaneous perforators were analyzed for total...

ANESTHETIZED patients who undergo surgical procedures may develop ulnar neuropathy. 1-6 Although the mechanism of ulnar neuropathy in the perioperative setting is often unclear, improper positioning or padding of the upper extremity during surgery is sometimes implicated’,’; however, there is little direct evidence to implicate improper intraoperative care as a cause of perioperative ulnar neur...
