During the Late Cretaceous, the continent of North America was divided into two sections: Laramidia in the west and Appalachia in the east. Although the sediments of Appalachia recorded only a sparse fossil record of dinosaurs, the dinosaur faunas of this landmass were different in composition from those of Laramidia. Represented by at least two taxa (Appalachiosaurus montgomeriensis and Drypto...

A radiographic review of first metatarsophalangeal joint (MPJ) arthrodesis in patients who had preoperative intermetatarsal angles greater than 15 degrees is presented. The average reduction of the intermetatarsal angle was measured. Twenty-one patients with 22 fusions, with ages ranging from 43 to 79 years old, underwent first MPJ arthrodesis with screw or pin fixation as determined appropriat...

BACKGROUND Despite the ability of lateral closed-wedge osteotomy for cubitus varus deformity to restore carrying angle and preserve elbow motion, there have been reports of poor cosmetic appearance of the elbow because of lateral condylar prominence. METHOD We evaluated long-term results of remodeling of lateral condylar prominence after osteotomy in 11 patients (7 of the prepuberty group, 4 ...

Upper extremity fractures account for up to 90% of paediatric fractures. Amongst these fractures, Supracondylar Humerus fractures are one of the most common requiring surgical intervention and have a high prevalence of associated short term complications such as nerve injuries and long term complications such as cubitus varus. The epidemiology, classifications, clinical evaluation and complicat...

Seventy patients who had sustained supracondylar fractures of the humerus as children were examined. Loss of carrying angle of the elbow occurred if the fracture was immobilized in a varus position during healing. Varus malalignment could have been obviated if comparative radiographs of the other elbow had been taken and the Baumann angles compared. Rotation and posterior displacement at the fr...

[Purpose] Walking with the feet turned inward or outward often causes issues for the people with these walking patterns. The purpose of this study was to examine the influence of in-toeing and out-toeing on maximum force and the center of pressure (COP) trajectory length during stair walking. [Subjects and Methods] The subjects were 30 female university students without orthopedic diseases of t...

OBJECTIVE The purpose of this study was to establish test-retest reliability values for the newly designed grip and wrist attachments of the BTE Primus and to determine criterion-related validity of the new grip attachment against the Jamar dynamometer. An additional purpose was to explore the differences in grip and wrist flexion strength between wheelchair users and control participants witho...

The exact cause of lameness in the proximal metacarpal and metatarsal region in horses can be difficult to determine when traditional diagnostics do not yield a diagnosis. High field-strength magnetic resonance imaging (MRI) provides clear evaluation of the proximal metacarpus/metatarsus in horses with performance-limiting injuries. The ability to accurately diagnose the source of lameness is i...

Results Whole body bone scan revealed asymmetrical increased up take in ankle and linear increased up take in left metatarsus (3th). His abdominal CT Scan showed multiple variable size hypodense lesions in bilateral kidneys and buldging and distortion of renal border. Bone marrow biopsy performed that revealed positive for CD45 and CD3. His renal lesions biopsy confirmed the diagnosis of Malign...
