OBJECTIVE:

To describe the technique for, and long-term clinical outcome of, a modified hip toggle stabilization using the TightRope® system for coxofemoral luxation repair.

STUDY DESIGN:

Retrospective case series.

METHODS:

OBJECTIVE:

To systematically evaluate the literature reporting outcome of surgical treatments for canine hip dysplasia (CHD) and to evaluate whether adequate evidence exists to support a procedure that will allow a consistent return to normal function.

STUDY DESIGN:

Systematic literature review.

ANIMALS:

Dogs with naturally occurring CHD.

A five-year-old male German shepherd dog presented with traumatic craniodorsal luxation of the right coxofemoral joint with pre-existing moderate hip dysplasia. A femoral head and neck ostectomy was performed. The patient was sedated with acepromazine and morphine administered intramuscularly. A lumbosacral epidural was performed using a combination of morphine and ropivacaine. Intraoperatively, an infusion of medetomidine, morphine, lidocaine, and ketamine was administered intravenously, and oxygen was administered via facemask.

OBJECTIVES:
The aim of this study was to compare Norberg angle, linear femoral overlap and surface femoral overlap in radiographs of hips accepted for official hip dysplasia screening.
METHODS:
Radiographs of 100 dogs (200 hips) were reviewed. The three measurements were performed in each hip according to previously described methods and thereafter correlated.

Objectives: To evaluate how the inclination and torsional deformity of the hemipelvis using extra-rotation as a model affect acetabular angle (AA) and dorsal acetabular rim angle (DARA) assessment with computed tomography (CT). Methods: A normal canine hemipelvis positioned in dorsal recumbency was scanned with a 16-slice multidetector CT scanner, with different degrees of torsional deformity, using extra-rotation around the long axis (0-5-10-15°) of the hemipelvis.

Loosening of the acetabular cup is one of the most common complications following total hip replacement and has an incidence rate of 1.8% to 36.8%. The objective of this study was to describe the surgical technique for the application of a cementless acetabular component specifically designed for treatment of cup loosening and preliminary clinical experience.

OBJECTIVE:
To evaluate whether cerclage wire or a lateral plate increases the peak-torque load to failure, compared to femora without adjunctive fixation, in femora implanted with Zurich Cementless stems.
STUDY DESIGN:
In vitro biomechanical study.
SAMPLE POPULATION:
Paired femora from adult dogs (n = 24) weighing 28-35 kg.

In Canada, the Ontario Veterinary College (OVC) has offered radiographic screening for hip dysplasia for many years, but there are other options for this service including the Orthopedic Foundation for Animals (OFA). There are some differences between the OFA and the OVC methods, and this study compares the OVC and OFA hip certification results in 37 dogs. There was good agreement between the two programs but in some instances there was a difference in the pass/fail status of a dog. Neither the OFA nor the OVC was more likely to fail or pass a given dog.
