Isolated lesions of the posterior interosseous nerve of the forearm are uncommon. Most follow injury to the elbow region The clinical features of a long-standing lesion of the nerve are wasting of the posterior forearm muscles (excepting brachio-radialis and extensor carpi radialis longus), diminution or loss of active extension of the fingers at the metacarpo-phalangeal joints, and weakness or...

A man aged sixty-two years complained of inability to extend his left index finger and thumb. This paralysis had been progressing for about twelve weeks, and had been accompanied by pain in the upper arm radiating into the forearm. On examination, there was paralysis of the extensor muscles of the left thumb and index finger. There were no sensory changes. In the extensor muscles, just distal t...

Bilateral posterior interosseous nerve palsy in a rheumatoid patient is described. Six previous case reports and our experience indicate that steroid injection into the elbow may not produce lasting recovery and may lead to unacceptable delay before surgical decompression. An anterolateral approach for division of the arcade of Frohse is effective in cases with diffuse synovitis; where there is...

Two patients presented with a posterior interosseous nerve palsy with supinator weakness. In each case an intraneural neurofibroma was found proximal to the supinator tunnel with no other stigmata of von Recklinghausen's disease. Both tumours showed a whorl-like histological pattern that has been previously confused with onion-bulb structures in hypertrophic polyneuropathy. Electron-microscopy ...

PURPOSE The purpose of this study was to evaluate the ultrasonographic findings associated with posterior interosseous nerve (PIN) syndrome. METHODS Approval from the Institutional Review Board was obtained. A retrospective review of 908 patients' sonographic images of the upper extremity from January 2001 to October 2010 revealed 10 patients suspicious for a PIN abnormality (7 male and 3 fem...

Background. Due to anatomical proximity to bone, the radial nerve is the most frequently injured major nerve of the upper extremity, frequently secondary to fractures (Li et al. (2013)). We describe an incidence when a branch of the radial nerve is injured as a result of a thermal injury. Observation. Radial nerve injury can occur anywhere along the anatomical course with varied etiologies, but...

Abstract Multiple epiphyseal dysplasia is a condition that courses with retarded development and may cause joint dysmorphia. We report case of posterior interosseous nerve palsy in child dysplasia. After physical examination complementary diagnostic tests revealed compression neuropathy, surgical neurolysis og the was performed at level arcade Frohse. The satisfactory evolution patient confirme...

PURPOSE Radial tunnel syndrome refers to pain on the lateral aspect of the forearm as a result of compression of the posterior interosseous nerve within a tunnel with specific anatomical boundaries. Diagnosis of the condition is difficult because of its close association with lateral epicondylitis, which warrants different methods of treatment. Based on a cadaveric study, a new clinical test, t...
