BACKGROUND The superficial palmar arch (SPA) and deep palmar arch (DPA) provide the dominant vascular supply to the hand. The SPA is considered to be highly variable and can be classified as either complete or incomplete. The simplest definition states that the anastomosis between the vessels contributing to the arch represent a complete arch, while an incomplete arch is described as characteri...

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...

account for approximately 3% of all biceps tendon ruptures. The two-incision repair techniques, as described by Boyd and Anderson1 in 1961, were developed to lower the risk of injury to the radial nerve and posterior interosseous nerve. Reports of posterior interosseous nerve palsy following this approach are rare.2-3 Transient posterior interosseous nerve palsies following a repair with the tw...

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...

OBJECTIVES To describe the relationship of the major muscular, ligamentous and neurovascular structures in relation to standard medial elbow arthroscopic portals used in dogs, and to evaluate their potential iatrogenic lesions. DESIGN Anatomical study using 20 canine cadaveric elbows. METHODS Arthroscopic explorations were performed using medial portals. Three 4 mm orthopaedic pins were int...

PURPOSE We present a systematic study of the anatomical relationships between intrarenal arteries and the kidney collecting system in pigs. MATERIALS AND METHODS The intrarenal anatomy (collecting system and arteries) was studied in 91, 3-dimensional endocasts of the kidney collecting system together with the intrarenal arteries. RESULTS Some anatomical details that have importance to help ...
