An 83-year-old woman presented with weakness in her right-hand and wrist extensors and swelling in the proximal part of the right forearm. Electromyography (EMG) confirmed involvement of posterior interosseous nerve at the level of proximal forearm. MR imaging demonstrated the characteristics of lipoma which extended on the anterolateral aspect of the right forearm and at the level of the radiu...

In severe forearm injuries, the diagnosis of disruption of the interosseous membrane is frequently delayed and sometimes missed, giving difficulties in the salvage of forearm stability. We studied the structure and function of the interosseous membrane in 11 cadaver preparations, using mechanical and histological analysis. Seven of the specimens tested in uniaxial tension sustained a mid-substa...

results first needle placement without imaging resulted in blood return in 1/199 participants and positive epidurography in 179/199 (90%). minimal needle repositioning resulted in a positive epidurogram in the remaining 19 attempts. no intravascular injection patterns were observed. conclusions this compares favorably to published success rates of fluoroscopically-guided technique and was well ...

Dear Editor, I read with interest the case by Ulucay et al. [1] regarding a patient with chest discomfort in whom angiography revealed two separate left circumflex (LCx) arteries, one arising from the left main coronary artery and the other from the ostium of the right coronary artery. The patient refused to undergo computed tomography angiography (CTA) to define the course of the right-sided L...

Histology of the SAN was studied in 5 female turkeys by using routine histological techniques. The SAN was lied in the region between the orifices of the right cranial vena cava and of the caudal vena cava and beneath the atrial epicardium. Its shape was conical to a limited degree. Its cranial end was near the right auricle and it was narrower than the caudal end. The caudal end was near the l...

During embryonic life, events may alter the normal growth and fusion of the endocardial tube, the paired dorsal aortae, and the vitelline plexus, leading to anomalies and variants of the mature axial arterial system.1 Many of these are well known, especially those associated with the aorta, heart, and umbilical artery.1,2 Vitelline variants have also been found that are either associated with M...

A comparison was made of the results produced by the circumtibial and interosseous routes of transfer of tibialis posterior for the correction of foot drop due to leprosy neuritis. The findings in 69 feet, of which 63 also had elongation of tendo Achillis, showed that the interosseous route gave a much lower incidence of recurrent inversion deformity of the foot. The results, in terms of improv...

Two cases of palsy of the anterior interosseous nerve were recently observed, each complicating a closed forearm fracture. A detailed description of this nerve lesion in association with a fracture has not, to my knowledge, been reported previously. The object of this paper is to record the findings and prognosis of the discrete nerve lesion observed in these two cases, and in addition to sugge...

The anterior interosseous nerve is a branch of the median nerve. It arises from the median nerve just distal to the antecubital fossa, about 5.5 cm distal to the medial epicondyle of the humerus. [2] It passes along the interosseous membrane between the ulna and radius. It terminates in the pronator quadratus muscle around the level of the wrist. It is largely a motor nerve. It supplies the fle...
