Retinoic acid arthropathy typically presents in the axial skeleton as flowing ossification along the anterior longitudinal ligament and as a condition of pelvic hyperostosis. When the appendicular skeleton is involved, radiographic findings usually present late and are typically asymmetric. We present an unusual case of retinoic acid arthropathy presenting in both elbow joints. Radiologists sho...

Wounds of the horse’s foot are common, and many are simple and heal without untoward consequences. Unfortunately, others may cause lasting changes in hoof function, and sometimes even be life threatening. The term foot describes the hoof and all structures contained within it. It is part of the appendicular skeleton and as such most of the same elements, i.e. bones, joints, tendons and ligament...

Leukemia is the most common childhood cancer and accounts for 30-40% of all malignancies. A retrospective review was performed of the hospital records of 9 children, 6 boys and 3 girls, aged from 2.5 to 15 years with ALL initially referred to Nemazee hospital Nuclear medicine center for whole body bone scanning between 2000 and 2002. Bone marrow pathology established ALL (L1) in two and ALL (L2...

Chondrosarcoma (CSA), fibrosarcoma (FSA), and hemangiosarcoma (HSA) are also considered primary bone tumors, although they are diagnosed much less frequently. Other tumors with skeletal involvement, s...

#{149} Be familiar with the radiologic manifestations that allow differentiation of the majority of enchondromas and intramedullary chondrosarcomas affecting the appendicular skeleton. Distinction of enchondroma versus intramedullary chondrosarcoma a!fecting the appendicular skeleton (proximal to the metacarpals and metatarsals) is a frequent diagnostic dilemma. The authors studied a large seri...

Mice carrying a targeted disruption of BmprIB were generated by homologous recombination in embryonic stem cells. BmprIB(-/-) mice are viable and, in spite of the widespread expression of BMPRIB throughout the developing skeleton, exhibit defects that are largely restricted to the appendicular skeleton. Using molecular markers, we show that the initial formation of the digital rays occurs norma...

Surgical treatment of metastatic cancer in the appendicular skeleton is well supported in the literature. Straightforward indications include pathologic fracture and impending pathologic fracture [1, 2]. More controversial indications for operative treatment exist regarding resection or en-bloc removal for solitary metastases or other painful metastases [3]. Overall, surgical decision making mu...
