MEDIAN nerve compression at the wrist is common and its treatment by decompression is usually successful. Ulnar nerve entrapment, on the other hand, is uncommon. The ulnar nerve as it enters the hand passes through and divides in the canal of Guyon, into its deep (motor) and superficial (sensory) branch. This ulnarcarpal tunnel is bounded proximally and medially by the pisiform, distally and la...

conclusions obtained results demonstrate significant differences between intraneural and perineural injection pressures in the median, ulnar, and radial nerves. intraneural injection pressures show low specificity but high sensitivity suggesting that pressure monitoring might be a valuable tool in improving the safety and efficacy of peripheral nerve blockade in regional anesthesia. peripheral ...

The aim of this retrospective study was to investigate the frequency of persistent ulnar affection in patients who underwent open reduction and internal fixation (ORIF) of distal humeral fractures without ulnar nerve transposition or mobilisation. Eighty-two patients (53 women), mean age 62 years, were, at a mean of 48 months, reviewed through medical records and a subjective evaluation form co...

We report a patient with primary ulnar entrapment neuropathy in the midarm. Stimulation of multiple sites along the ulnar nerve showed a motor conduction block at a distance of 7.5-10 cm proximal to the medial epicondyle, where the nerve was compressed by the medial intermuscular septum. Anatomically, the possibility of ulnar nerve entrapment in this segment has long been suggested, and stimula...

Guyon's canal syndrome is a compression neuropathy of the ulnar nerve entrapment at the wrist. Compression of the ulnar nerve at the wrist by a ganglion, lipomas, diseases of the ulnar artery, fractures of the hamate and trauma are common etiologcal factors. Unlike Guyon's canal syndrome, carpal tunnel syndrome (CTS) is the most common nerve entrapment of the upper extremity. Although, open (OC...

Double compression of the ulnar nerve, including Guyon's canal syndrome associated with cubital tunnel syndrome caused by the anconeus epitrochlearis muscle, is a very rare condition. We present a case of double crush syndrome of the ulnar nerve at the wrist and elbow in a 55-year-old man, as well as a brief review of the literature. Although electrodiagnostic findings were consistent with an u...

The diagnosis of ulnar nerve entrapment at the elbow has relied primarily on clinical and electrodiagnostic findings. Magnetic resonance imaging (MRI) has been used in the evaluation of peripheral nerve entrapment disorders to document signal and configurational changes in nerves. In this case report we review the MRI and operative findings of a rare constriction band causing ulnar nerve compre...

<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>

Nerve transfers for peripheral nerve injuries have become increasingly popular over the past two decades. While techniques ulnar repair been well-documented, more recent median and radial branch reinnervation are still being explored. This review describes outcomes of common emerging distal branches nerves.
