Meralgia paresthetica refers to the entrapment of the lateral femoral cutaneous nerve at the level of the inguinal ligament. The lateral femoral cutaneous nerve - a purely sensory nerve - arises from the L2 and L3 spinal nerve roots, travels downward lateral to the psoas muscle, and then crosses the iliacus muscle. Close to the anterior superior iliac spine, the nerve courses in contact with th...

A case of ulnar nerve entrapment in Guyon's tunnel caused by an aberrant palmaris muscle, associated with a patent median artery and duplication of the median nerve, is reported.

We report a recurrent Piriformisc muscle syndrome after surgical release. After the primary neurolysis, a second operation was performed to release adhesions. This case shows a different type of sciatic nerve entrapment by an abnormal thin muscle slip. Results of the revision surgery guide us to the point that revision surgery for Piriformis muscle syndrome should be meticulously selected, and ...

Operative release for entrapment of the suprascapular nerve was carried out in 35 patients. They were assessed at an average of 30 months (12 to 98) after operation using the functional shoulder score devised by Constant and Murley. The average age at the time of surgery was 40 years (17 to 67). Entrapment was due to injury in ten patients and no cause was found in three; 34 had diffuse postero...

Introduction. The catheter "pinch-off syndrome" has been described to be secondary to crimping of the catheter between the clavicle and the first rib, as well as entrapment of the catheter at the site of penetration of the subclavius muscle. The lateral insertion technique has been recommended to prevent catheter pinch-off, but it is unknown if this technique can prevent entrapment by the subcl...

Radial nerve compression or injury can occur at any point along the course of the nerve within the upper extremity. Entrapment of the radial nerve or its branches is most common within the proximal forearm and at the elbow. Variations in anatomic structures at this level are an important cause of radial nerve entrapment syndromes. Compression of the radial nerve and its branches at the elbow ca...

This study aimed at identifying the anatomic structures which may be responsible for entrapment neuropathies of the median nerve. Thirty upper extremities of 15 formalin fixed adult cadavers were dissected from the axilla to the distal forearm under Zeiss Opmi 9--FC microscope. We encountered seven different anatomic structures that may compress the median nerve. These structures are the brachi...
