Case Description-A 10-year-old spayed female Jack Russell Terrier and a 7-year-old neutered male mixed-breed dog were evaluated because of acute, progressive, unilateral forelimb lameness associated with signs of pain and turgid antebrachial swelling. Clinical Findings-For either dog, there were no salient pathological or diagnostic imaging abnormalities. A diagnosis of compartment syndrome was confirmed on the basis of high caudal antebrachial compartmental pressure in the affected forelimb. Treatment and Outcome-Both dogs underwent surgical exploration of the affected forelimb.

This report describes limb-sparing surgery in a 35 kg, six-year-old Hungarian Vizsla with a distal radial lytic bone lesion. Preoperative biopsy had suggested a bone cyst, however histopathology on the excised bone segment was indicative of an osteosarcoma. Following excision of the tumour, the bone defect was filled with a composite bone graft and stabilized with a custom-made dorsal 3.5/2.7 mm pancarpal arthrodesis plate and an orthogonally positioned medial 2.7 mm compression plate. This technique has not previously been described for limb-sparing procedures.

A six-year-old Labrador Retriever was presented for management of a 2 x 2 cm cutaneous mass over the dorsal aspect of the carpus. A fine needle aspirate performed by the referring veterinarian was consistent with a mast cell tumour. The ipsilateral prescapular lymph node was enlarged. Preoperative staging did not reveal any evidence of metastasis. Wide excision of the mass and prescapular lymphadenectomy were performed.

Objective-To characterize biomechanical differences in gait between dogs with and without an amputated thoracic limb. Animals-Client-owned dogs (16 thoracic-limb amputee and 24 quadruped [control] dogs). Procedures-Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance phase. Results-Amputees had significant increases in stance duration and vertical impulse in all limbs, compared with values for control dogs.

Objective-To evaluate biomechanical gait adaptations in dogs after amputation of a pelvic limb. Animals-Client-owned dogs (12 pelvic limb-amputee and 24 quadruped [control] dogs). Procedures-Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance phase. Results-Pelvic limb amputees had increased peak braking forces in the contralateral thoracic limb and increased propulsive forces and impulses in both the ipsilateral thoracic limb and remaining pelvic limb.

This report describes the use of a non-vascularized proximal cortical autograft from the ipsilateral ulna in limb-sparing surgery for the treatment of distal radial osteosarcoma. A pancarpal arthrodesis was performed to stabilize the site. Construct failure and probable local tumor recurrence were observed. The total survival time was 282 days.

Objective-To examine the biological behavior of ulnar osteosarcoma and evaluate predictors of survival time in dogs. Design-Retrospective case series. Animals-30 dogs with primary ulnar osteosarcoma. Procedures-Medical records were reviewed. Variables recorded and examined to identify predictors of survival time were signalment, tumor location in the ulna, tumor length, serum alkaline phosphatase activity, surgery type, completeness of excision, tumor stage, tumor grade, histologic subtype, development of metastases, and use of chemotherapy.
