Mandibular reconstruction after gunshot trauma in a dog by use of recombinant human bone morphogenetic protein-2.

Small animal - Trauma - Fracture Fixation and Implants - Biologics

Case Description-A 6-year-old German Shorthaired Pointer was evaluated for possible reconstruction of a mandibular defect resulting from gunshot trauma. Clinical Findings-A 5-cm defect of the right mandibular body was evident. A segment of the mandibular body was removed 9 weeks earlier because of severe contamination and comminution associated with gunshot trauma. Subsequent right-sided mandibular drift resulted in malocclusion in which the left mandibular canine tooth caused trauma to mucosa of the hard palate medial to the left maxillary canine tooth. ...

Measurement of serum carboxyterminal cross-linked telopeptide of type I collagen concentrations in dogs with osteosarcoma.

Small animal - Oncology - Biologics

Objective-To evaluate the usefulness of carboxyterminal cross-linked telopeptide of type I collagen (ICTP) concentrations for screening dogs for the presence of osteosarcoma. Sample Population-32 client-owned dogs with osteosarcoma (27 dogs with osteosarcoma of the appendicular skeleton and 5 dogs with osteosarcoma of the axial skeleton) and 44 non-tumor-bearing control dogs. Procedures-Serum was obtained from blood samples collected from dogs with osteosarcoma and from clinically normal dogs. ...

Biomechanical comparison of the pullout properties of external skeletal fixation pins in the tibiae of intact and ovariectomised ewes

Large animal - Miscellaneous - Ruminant

The pin-bone interface is the least stable component of the external skeletal fixator. Concerns exist regarding the ability to obtain adequate implant purchase in poor quality bone. Consequently, reduced bone quality has been viewed as a contra-indication for the use of external skeletal fixators. The aim of this study was to investigate the holding power of two different fixator pin designs in bone from entire and ovariectomised sheep. Thirty-two aged ewes were divided into two groups. Group 1 were controls, and Group 2 were ovariectomised (OVX). ...

Scapulohumeral osteochondrosis - A retrospective study of 32 horses

Large animal - Osteochondrosis - Equine

Objectives: To review the outcome of equine shoulder osteochondrosis (OC) with surgical or conservative treatment. Methods: Retrospective study of 32 horses, less than two years of age, with scapulohumeral joint (SHJ) OC. The lesion severity was graded based on measurements taken from lateromedial radiographs. Follow–up information was obtained from racing records or telephone conversations with owners. Successful outcome was defined as the ability of the horse to perform its intended use. Results: Sixteen of 32 horses were affected bilaterally (48 joints). ...
