This report aims to describe implant characteristics and procedure for implantation, and comment on and report the clinical outcomes in small dogs and cats using the new Zurich mini cementless total hip system.

Objective: To develop quantitative measures that, when combined with the Fédération Cynologique Internationale (FCI) score, would potentially enhance the accuracy of the scoring process.

Animals: 153 client-owned purebred German Shepherd Dogs with normal and near normal (71 dogs) and dysplastic coxofemoral joint (82 dogs).

Complications and long-term clinical outcomes for 15 dogs surgically treated for traumatic craniodorsal hip luxation by prosthetic capsule replacement (PCR) with a prosthetic ligament were retrospectively reviewed.

A PCR technique with capsulorrhaphy was performed in all dogs using acetabular screws with washers and a femoral tunnel as anchor points for the polyester prosthetic ligament. A non-weight-bearing sling was not placed. Minimum 1 yr follow-up period was required for study inclusion.

Hip dysplasia is a common orthopaedic condition in dogs and stress radiography is the best diagnostic tool for early diagnosis.

Objectives: Two-dimensional measurements of acetabular geometry are widely used for the assessment of acetabular component orientation following total hip replacement (THR). With the increasing availability of computed tomography scans, there is an opportunity to develop three-dimensional (3D) planning to improve surgical accuracy. The aim of this study was to validate a 3D workflow for measuring angles of lateral opening (ALO) and version, and to establish reference values for dogs.

Objective: To describe and evaluate minimally invasive repair of acetabular fractures in dogs using plates contoured to 3D-printed hemipelvic models.

Study design: Ex vivo feasibility study and case report.

Sample population: Adult canine cadavers (n = 5); 8 year old male neutered Chihuahua.

Objective: To report the outcomes and cost-benefit analysis of preclosure povidone-iodine lavage (PrePIL) used to reduce the risk of infection following total hip replacement (THR) surgery.

Study design: Retrospective study.

Animals: One thousand six hundred ninety-nine dogs, 17 cats.

Objective: To compare ex vivo postimplantation biomechanical characteristics of 3 implants for canine total hip replacement: a cementless press-fit femoral stem with a pin in the femoral neck (p-pfFS), a press-fit cementless femoral stem without this pin (pfFS), and a cemented femoral stem (cFS).

Sample: 18 cadaveric femurs from 9 dogs.

Objectives: The aim of our study was to describe a biomechanical testing protocol to reproduce ex vivo craniodorsal hip luxation specific to the feline model, and evaluate the biomechanical properties of an intact hip joint compared with the fixation strength of two different techniques of extra-articular hip stabilisation.
