Several similar projections utilizing cranial and caudal angulation of the X-ray tube in various obliquities have been described recently for coronary angiography and left ventriculography. These views provide improved visualization of the proximal branches of the left coronary artery, the region of the crux of the right coronary artery, and the left ventricle in the left anterior oblique proje...

Posterior interosseous nerve entrapment is a potential cause of upper extremity muscle weakness and pain. The diagnosis may be difficult to make clinically, and electrodiagnostic tests may not identify the exact site of nerve compression. We report a case of posterior interosseous nerve entrapment in which electrodiagnostic studies suggested radial neuropathy at the level of the spiral groove, ...

INTRODUCTION We report an extremely rare case of tardy posterior interosseous nerve palsy that developed 40 years after unreduced anterior dislocation of the radial head in a Monteggia fracture. CASE PRESENTATION A 46-year-old Asian woman was diagnosed with tardy posterior interosseous nerve palsy resulting from residual dislocation of the radial head in a Monteggia fracture. The patient reme...

Doppler ultrasonography was used to compare blood flow characteristics in the caudal artery of heifers fed diets with endophyte (Neotyphodium coenophialum) noninfected (E-, 0 microg of ergovaline/g of DM), a 1:1 mixture of endophyte-infected and E- (E+E-; 0.39 microg of ergovaline/g of DM), or endophyte-infected (E+, 0.79 microg of ergovaline/g of DM) tall fescue (Lolium arundinaceum) seed. Eig...

OBJECTIVES Preclinical studies using large animal models play an intergral part in translational research. For this study, our objectives were: to develop and validate arthroscopic approaches to four compartments of the stifle joint as determined via the gross and arthroscopic anatomy of the cranial and caudal aspects of the joint. METHODS Cadaveric hindlimbs (n = 39) were harvested from matu...

BACKGROUND Myofascial pain (MP) is a common disorder that can involve any skeletal muscle in the human body. There are no published reports of the referred pain patterns of the third and fourth dorsal interosseous muscles. OBJECTIVE To investigate the referred pain patterns of the third and fourth dorsal interosseous muscles. STUDY DESIGN Prospective evaluation. SETTING Academic medical c...

In the correction of footdrop due to leprosy neuritis the tibialis posterior muscle is re-routed and used to provide dorsiflexion of the foot. This study of tibialis posterior transfer was carried out to compare the results of the circumtibial and interosseous routes. There is no significant difference in the range of motion between either route through the range of the interosseous route is mo...

The median artery usually regresses after the eighth week of intrauterine life, but in some cases it persists into adulthood. The persistent median artery (PMA) passes through the carpal tunnel of the wrist, accompanying the median nerve. During anatomical dissection in our department, we found two unilateral cases of PMA originating from the ulnar artery. In both cases the PMA passed through t...
