Osteosarcoma (OS) is the most common primary bone tumor of dogs, accounting for approximately 85% of malignancies arising in the skeleton. It is a high grade, biologically aggressive neoplasm of mesenchymal origin that closely parallels human OS. It is estimated that 10,000 dogs per year develop OS in the United States. The peak incidence of canine OS occurs primarily in middleaged to older ani...

Periosteal chondrosarcomas, also known as juxtacortical are a rare subtype of chondrosarcoma. They usually present with pain and swelling over the affected site, most often arising in appendicular skeleton, metaphysis distal femur humerus common sites. In this poster we case report periosteal chondrosarcoma on internal surface right 8th rib, making an unusual site for such tumour. chondrosarcom...

The processes of ossification sequences are poorly investigated for birds in general, even for domestic and experimental species and when it comes to the waterfowl it is almost negligible. Such sequences constitute a rich source of data on character evolution, and may even provide phylogenetic information. A pre-hatch developmental study on ossification sequences of axial and appendicular skele...

BACKGROUND Excision of a bone tumor requires reconstruction if limb salvage is a priority. Reconstruction with an endoprosthetic implant is preferred in our unit, as the patient typically can return rapidly to full weight-bearing and functional activities. Long-term complications, such as deep infection, aseptic loosening, and mechanical failure of the implants, have led to concerns about the e...

The Hox genes encode a group of transcription factors essential for proper development of the mouse. Targeted mutation of the Hoxd11 gene causes reduced male fertility, vertebral transformation, carpal bone fusions, and reductions in digit length. A duplication of the Hoxd11 gene was created with the expectation that the consequences of restricted overexpression in the appropriate cells would p...
