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.

Authors: Sumaya Allaith et al.

Objective: To report outcomes and complications associated with total hip replacements (THR) using a multiuser canine hip registry (CHR) and owner-administered questionnaire.

Study design: Prospective longitudinal clinical study.

Animals: Dogs (n = 1852).

Objective: The aim of this study was to describe an arthroscopic-assisted technique for coxofemoral toggle rod placement, and to report on the feasibility, drill tunnel trajectory and accuracy of tunnel aperture location using this method.

Study design: Cadaveric pilot study.

Sample population: Eight coxofemoral joints.

Authors: Verónica Rodiño Tilve et al.

Objective: To report indications, complications, and long-term outcomes following feline total hip replacement (THR) using a client-based clinical metrology questionnaire, the Feline Musculoskeletal Pain Index (FMPI), and owner satisfaction.

Study design: Multi-institutional retrospective cohort study.

Animals: Cats (n = 44) that underwent THR (n = 56).

Hip dysplasia is one of the most common orthopedic conditions affecting dogs.

Initially, laxity of the femur leads to subluxation, and subluxation can lead to an abnormal development or to progressive degeneration of the femoral head and dorsal acetabular rim.

Osteoarthritis and its clinical impact progress over time. Changes to the femoral head and neck and the acetabulum and the impact on joint motion and pain vary widely among dogs.

The concept of a novel patient-specific 3D-printed shelf implant should be evaluated in a relevant large animal model with hip dysplasia. Therefore, three dogs with radiographic bilateral hip dysplasia and a positive subluxation test underwent unilateral acetabular augmentation with a 3D-printed dog-specific titanium implant. The contralateral side served as control.

Case history: Medical records of a single private practice (Illinois, USA) were retrospectively reviewed to identify dogs (n = 24) that had an open hip reduction with a transarticular suture stabilisation technique after presenting with a traumatic coxofemoral luxation between April 2003 and December 2018.

Objective: To describe the surgical technique and report the long-term outcome of greater trochanteric osteotomy (GTO) as a component of cementless total hip replacement (THR) in dogs with severe medialization of the greater trochanter or chronic craniodorsal hip luxation.

Study design: Short case series.

Animals: Four dogs treated with five THRs.
