Musculoskeletal Ultrasound Technical Guidelines II. Elbow
European Society of MusculoSkeletal Radiology Musculoskeletal Ultrasound Technical Guidelines II. Elbow Ian Beggs, UK Stefano Bianchi, Switzerland Angel Bueno, Spain Michel Cohen, France Michel Court-Payen, Denmark Andrew Grainger, UK Franz Kainberger, Austria Andrea Klauser, Austria Carlo Martinoli, Italy Eugene McNally, UK Philip J. O’Connor, UK Philippe Peetrons, Belgium Monique Reijnierse, The Netherlands Philipp Remplik, Germany Enzo Silvestri, Italy Elbow Note The systematic scanning technique described below is only theoretical, considering the fact that the examination of the elbow is, for the most, focused to one quadrant only of the joint based on clinical findings. 1 ANTERIOR ELBOW For examination of the anterior elbow, the patient is seated facing the examiner with the elbow in an extension position over the table. The patient is asked to extend the elbow and supinate the fore- arm. A slight bending of the patient’s body toward the examined side makes full supination and as- sessment of the anterior compartment easier. Full elbow extension can be obtained by placing a pillow under the joint. Transverse US images are first obtained by sweeping the probe from approximately 5cm above to 5cm below the trochlea-ulna joint, a Pr perpendicular to the humeral shaft. Cranial US images of the supracondylar region reveal the superficial biceps and the deep brachialis mu- Br scles. Alongside and medial to these muscles, follow the brachial artery and the median nerve: * the nerve lies medially to the artery. * Legend: a, brachial artery; arrow, median nerve; arrowheads, distal biceps tendon; asterisks, articular cartilage of the Humerus humeral trochlea; Br, brachialis muscle; Pr, pronator muscle 2 distal biceps tendon: technique The distal biceps tendon is examined while keeping the patient’s forearm in maximal supination to bring the tendon insertion on the radial tuberosity into view. -
Structure of the Flexor Digitorum Superficialis
Okajimas Folia Anat. Jpn., 56(5) : 277-288, December 1979 Structure of the Flexor Digitorum Superficialis By OSAMU OHTANI Department of Anatomy, Okayama University Medical School, Okayama 700, Japan (Director : Prof. Dr. H. Outi) —Received for Publication, March 9, 1979— Key Words: Flexor digitorum superficialis, Striated muscle, Forearm musculature. Summary. Fifty-two forearms of 26 Japanese adult cadavers were examined. The flexor digitorum superficialis can be separated into two layers: a superficial layer and a deep layer. The superficial layer is composed of the radial head and the superficial part of the humeroulnar head. It forms two muscle bellies which give rise to the tendons for the third and fourth digits, respectively. The deep layer is composed of the deep part of the humeroulnar head. After forming an inter- mediate tendon, the deep layer also divides into two fleshy bellies which give rise to the tendons for the second and fifth digits, respectively. Based on the mode of occurrence of the communicating muscle fasciculi between the superficial layer and the deep layer, the flexor digitorum superficialis can be classified into four types. Type I muscle has no communicating fasciculus (4/52, 7.7%). Type II muscle has a communicating muscle fasciculus between the intermediate tendon and the muscle belly for the fourth digit (muscle fasciculus A) (29/52, 55.8%). Type III muscle has the muscle fasciculus A as well as another communicating muscle fasciculus between the intermediate tendon and the belly for the third digit (muscle fasciculus B) (18/52, 34.6%). Type IV muscle has the muscle fasciculus B only (1/52, 1.9%). -

Anatomical Considerations of Fascial Release in Ulnar Nerve Transposition: a Concept Revisited
LABORATORY INVESTIGATION J Neurosurg 123:1216–1222, 2015 Anatomical considerations of fascial release in ulnar nerve transposition: a concept revisited Mark A. Mahan, MD,1 Jaime Gasco, MD,2 David B. Mokhtee, MD,3 and Justin M. Brown, MD4 1Division of Neurological Surgery, Barrow Neurological Institute, St. Joseph’s Hospital and Medical Center, Phoenix, Arizona; 2Division of Neurological Surgery, University of Texas Medical Branch, Galveston, Texas; 3Tulsa Bone and Joint Associates, Tulsa, Oklahoma; and 4Division of Neurosurgery, University of California, San Diego, La Jolla, California OBJECT Surgical transposition of the ulnar nerve to alleviate entrapment may cause otherwise normal structures to become new sources of nerve compression. Recurrent or persistent neuropathy after anterior transposition is commonly attributable to a new distal compression. The authors sought to clarify the anatomical relationship of the ulnar nerve to the common aponeurosis of the humeral head of the flexor carpi ulnaris (FCU) and flexor digitorum superficialis (FDS) muscles following anterior transposition of the nerve. METHODS The intermuscular septa of the proximal forearm were explored in 26 fresh cadaveric specimens. The fibrous septa and common aponeurotic insertions of the flexor-pronator muscle mass were evaluated in relation to the ulnar nerve, with particular attention to the effect of transposition upon the nerve in this region. RESULTS An intermuscular aponeurosis associated with the FCU and FDS muscles was present in all specimens. Transposition consistently resulted in angulation of the nerve during elbow flexion when this fascial septum was not released. The proximal site at which the nerve began to traverse this fascial structure was found to be an average of 3.9 cm (SD 0.7 cm) from the medial epicondyle. -
Areas 1- Ern Africa
Kroeber Anthropological Society Papers, Nos. 71-72, 1990 Diet, Species Diversity and Distribution of African Fossil Baboons Brenda R. Benefit and Monte L. McCrossin Based on measurements ofmolarfeatures shown to befunctionally correlated with the proportions of fruits and leaves in the diets ofextant monkeys, Plio-Pleistocenepapionin baboonsfrom southern Africa are shown to have included more herbaceous resources in their diets and to have exploited more open country habitats than did the highlyfrugivorousforest dwelling eastern African species. The diets ofall species offossil Theropithecus are reconstructed to have included morefruits than the diets ofextant Theropithecus gelada. Theropithecus brumpti, T. quadratirostris and T. darti have greater capacitiesfor shearing, thinner enamel and less emphases on the transverse component ofmastication than T. oswaldi, and are therefore interpreted to have consumed leaves rather than grass. Since these species are more ancient than the grass-eating, more open country dwelling T. oswaldi, the origin ofthe genus Thero- pithecus is attributed tofolivorous adaptations by largepapionins inforest environments rather than to savannah adapted grass-eaters. Reconstructions ofdiet and habitat are used to explain differences in the relative abundance and diversity offossil baboons in eastern andsouthern Africa. INTRODUCTION abundance between eastern and southern Africa is observed for members of the Papionina (Papio, Interpretations of the dietary habits of fossil Cercocebus, Parapapio, Gorgopithecus, and Old World monkeys have been based largely on Dinopithecus).

Development, Function and Evolution of Teeth
Development, Function and Evolution of Teeth Over the past 20 years there has been an explosion of information generated by scienti®c research. One of the bene®ciaries of this has been the study of morphology, where new techniques and analyses have led to insights into a wide range of topics. Advances in genetics, histology, microstructure, biomechanics and morphometrics have allowed researchers to view teeth from new perspectives. However, up to now there has been little communication between researchers in the different ®elds of dental research. This book brings together for the ®rst time overviews of a wide range of dental topics, linking genes, molecules and developmental mechanisms within an evolutionary framework. Written by leading experts in the ®eld, this book will stimulate co-operative research in ®elds as diverse as palaeontology, molecular biology, developmental biology and functional morphology.
