Objective: The aim of this study was to categorize the presentation, management, complications and long-term outcome of canine acetabular fractures, and to determine the factors affecting outcome.

Materials and methods: Case records and imaging for dogs with acetabular fractures were reviewed with long-term follow-up via canine brief pain inventory (CBPI) and owner questionnaires.

Authors: Samuel P Franklin, Nathan A Miller, Todd Riecks

Objective: The aim of this study was to quantify the complications using the Zurich total hip replacement system in an initial series of cases performed by a single surgeon who had experience with other total hip replacement systems.

Dislocation after total hip arthroplasty (THA) remains a troublesome complication, and a source of frustration for the owner and the surgeon.

The dislocation rate of hip prostheses in dogs is reported to range from 4 to 15%, representing the most common short-term complication. This is especially true in large and giant breed dogs, usually requiring revision surgery. With the increase in the number of THA being performed in veterinary surgery, reducing or preventing complications such as postoperative THA dislocation will be of paramount importance.

Objective: To review the outcome of dogs that underwent Zürich cementless total hip arthroplasty (Z-THA) for the repair of acute and chronic capital physeal fractures (CPF) and document the CPF-related hip remodeling.

Study design: Retrospective study.

Sample population: Fifty-three Z-THA in 53 dogs.

Authors: Jorge Espinel Rupérez et al.

Objective: To report overall rate and type of complications and outcomes of cats with coxofemoral luxation managed with hip toggle stabilization (HTS), to compare rate of postoperative complications and outcomes of cats treated with ultrahigh-molecular-weight-polyethylene (UHMWPE) or nylon, and to identify risk factors for reluxation and non-excellent outcomes.

Study design: Multi-institutional retrospective cohort study.
