enchymal dysplasia of bone that is diagnosed by a characteristic linear cortical hyperostosis with a flowing candle wax appearance (1-3). It commonly affects long bones, usually in the lower limb and on one side of the body. The involvement of flat bones is rare (1, 2). In addition, bilateral involvement is extremely rare, with only one case of long tubular bones with a symmetric distribution r...

Limb deformities in foals can be subdivided into two major groups: 1) angular limb deformities, in which there is deviation, primarily in the frontal plane, originating at a joint and/or growth plate; and 2) flexural limb deformities, in which there is persistent hyperflexion or hyperextension of the limb. These conditions are generally categorized under the umbrella term of developmental ortho...

Watson-Jones(l955)wrote “. . . inexceptional cases there mayeven be forward dislocation of both forearm bones without fracture. There is one case in which there can be no doubt about it; thejoint was dissected after the limb had been amputated-but that was long ago.” This happened in 1860. Forward dislocation of both forearm bones without fracture of the olecranon is in fact extremely rare. The...

The development of the vertebrate limb depends on an interplay of cellular differentiation, pattern formation, and tissue morphogenesis on multiple spatial and temporal scales. While numerous gene products have been described that participate in, and influence, the generation of the limb skeletal pattern, an understanding of the most salient feature of the developing limb--its quasiperiodic arr...

The poorly understood Triassic reptile Drepanosaurus is known for its excessively large claws. New discoveries demonstrate a remarkable modification of the bones in the wrist and forearm, a significant departure from the typical five-digit tetrapod limb.

Cerveny C.: Osteometry of the Ossa Sesamoidea Phalangis Proximalis in Cattle (Bos primigenius f. taurus Linne 1758). Acta vet. Brno, 54, 1985: 119-128. The sesamoid bones of the proximal phalanges of the digits from 14 bovine females of the Bohemian Spotted cattle were subject to osteometric examination. Statistical significance of four characteristics was studied. There was no statistical sign...

In this article, a method of using ultrasound to image a residual limb is presented. The method employs a compound scanning technique to reconstruct a cross-sectional image (a slice) of the limb in a transverse plane. By scanning the limb in many transverse planes, a three-dimensional (3-D) volumetric image can be obtained from which either a transverse slice, a longitudinal cross section, or a...
