Distal Extremities

Objective: To report modification of the endoprosthesis surgical limb‐salvage technique to treat a locally extensive osteosarcoma in a dog and associated functional outcome.

Study design: Clinical case report.

Animals: One client‐owned dog.

A 5-year-old female spayed Shetland sheepdog presented for evaluation of bandage sores on the left pelvic limb after a splint was placed to stabilise a digit fracture incurred approximately 2 weeks previously. Multiple areas of necrosis were identified upon bandage removal.

After debridement of devitalised tissue, a 4 cm wound on the plantar surface of the metatarsal bones (with exposed bone and tendons) remained.

OBJECTIVE: To describe the outcome of bone plate fixation of distal radius and ulna fractures in toy breed dogs treated with conventional bone plates.

METHODS: Records of 15 toy breed dogs with distal radius and ulna fractures were retrospectively reviewed for signalment, method of fixation, complications and clinical and radiographic assessments. A telephone-based owner questionnaire was conducted to determine long-term function and client satisfaction.

OBJECTIVES: To investigate proximal tibial anatomy and its influence on anisometry of extracapsular stabilizing sutures in small dog breeds.

An approximately three-month-old, 0.45 kg female Domestic Shorthaired kitten with stiff hyperextended hindlimbs distal to the talo-central joint is reported. Attempts at repositioning of the joints by flexion failed while increased manipulative forces caused signs of pain and vocalization. Orthogonal radiographic views revealed a significant malarticulation of the tarsus. Goniometric measurments revealed a 145° extensor and 95° internal torsional deformity. 

A young Labrador Retriever was presented for treatment of severe distal hindlimb necrosis caused by bandage ischemia. During digit amputation at the metatarsophalangeal joints, the third and fourth digital pads were salvaged and transferred to the metatarsal stump to create a weight-bearing surface. Negative pressure wound therapy (NPWT) was utilized for flap immobilization and to promote granulation tissue in the remaining wound defect.

OBJECTIVES: To describe the normal anatomy of the soft tissues of the canine tarsus as identified on computed tomography (CT) and magnetic resonance imaging (MRI) and to evaluate specific MRI sequences and planes for observing structures of diagnostic interest.

STUDY DESIGN: Prospective descriptive study.

ANIMALS: Canine cadavers (n = 3).

OBJECTIVE:  To evaluate the influence of epidemiologic, surgical, and mechanical factors on the durations of bone consolidation and external fixation after distraction osteogenesis in dogs.

STUDY DESIGN: Retrospective cohort study.

Objective: To report our clinical experience in the surgical treatment of feline thoraco-lumbar vertebral fracture-luxations using optimal safe implantation corridors as previously described in vitro. Study design: Retrospective clinical study. Materials and Methods: Medical records and radiographs of cats with vertebral fracture-luxations stabilized by screws and polymethylmethacrylate (PMMA) using optimal safe implantation corridors between 2009 and 2011 were reviewed.
