Anterior interosseous nerve syndrome (Kiloh-Nevin Syndrome) is the triad of weakness of the flexor pollicis longus, the flexor digitorum profundus of the index finger, and the pronator quadratus. It is a manifestation of neuropathy affecting either the anterior interosseous nerve itself (anterior interosseous neuropathy) or its fascicles more proximally within the median nerve or brachial plexu...

Nerve compression syndromes of the upper extremity, including carpal tunnel syndrome, cubital tunnel syndrome, posterior interosseous syndrome and radial tunnel syndrome, are common in the general population. Diagnosis is made based on patient complaint and history as well as specific exam and study findings. Treatment options include various operative and nonoperative modalities, both of which...

We successfully transplanted two free posterior interosseous artery perforator flaps that had been harvested simultaneously from a single posterior interosseous artery system to the index and middle fingers of a 19-year-old man. Our case suggests that multiple free perforator flaps can be prepared from a single posterior interosseous artery system.

Intraneural perineurioma is a benign tumor that occurs in less than 1% of peripheral nerve tumors; no more than 90 cases have been reported1,2. Tumorous lesions of the posterior interosseous nerve (PIN) have rarely been described3–5. An 18-year-old woman presented with a longstanding his tory of spontaneous progressive weakness in the PIN dis tribution (Figure 1). Ultrasonography and MRI studie...

Abstract Introduction neuromas are lesions resulting from abnormal nerve regeneration following a peripheral injury and may cause severe pain. Method we present case of 54-year-old female who developed painful cutaneous lesion over the first web-space hand an untreated glass laceration 3 years previously. Results surgical resection revealed 100% transection ulnar digital (UDN) thumb with into s...

The outcome of 260 repairs of the radial and posterior interosseous nerves, graded by Seddon's modification of the Medical Research Council Special Committee's system, was analysed according to four patterns of injury; open 'tidy', open 'untidy', closed traction, and those associated with injury to the axillary or brachial artery. We studied the effect on the outcome of delay in effecting repai...

The incidence of superficial arteries was studied in 68 (38 right and 30 left) upper extremities. One right limb of an adult male presented a superficial arterial pattern (2.63%, total 1.47%) resembling a superficial brachio-ulno-radial artery (SBUR). The median nerve crossed the superficial brachial artery (SBA) from the posterior to the medial side and again posterior to the same at the cubit...

We treated 31 patients with non-traumatic paralysis of the posterior interosseous nerve over 15 years. There were 10 men and 21 women of mean age 40.3 years (17 to 71). Six were managed conservatively, and 25 by operation. In 14 patients entrapment occurred at the supinator, including three who had double compression at both the entrance and exit from the muscle. In four it was caused by a gang...

The upper trunk of the brachial plexus is the most common area affected by neuralgic amyotrophy (NA), and paresis of the shoulder girdle muscle is the most prevalent manifestation. Posterior interosseous nerve palsy is a rare presentation in patients with NA. It results in dropped finger on the affected side and may be misdiagnosed as entrapment syndrome or compressive neuropathy. We report an ...
