Biomechanical Comparison of Spacer Pin Fixation to Two Established Methods of Tibial Tuberosity Transposition Stabilization in Dogs.

Objective:  The aim of this cadaveric study was to compare the biomechanical outcomes of three methods of stabilization for tibial tuberosity transposition to treat medial patellar luxation: a complete osteotomy with a two-pin and tension band wire (TBW) fixation (TBW group), a partial osteotomy with a two-pin fixation (2 Pin group), and a partial osteotomy with a spacer pin fixation (Spacer Pin group).

Study Design:  Thirty medium to large-sized canine cadaveric tibiae were dissected and randomly assigned to one of three groups: TBW, 2 Pin, and Spacer Pin groups. The patellar ligaments were loaded in tension until ultimate failure.

Outcome of rest with or without bandaging for treatment of carpal flexural contracture deformities in puppies: 47 puppies and 75 joints (2000-2018).

Objective: To review outcome of dogs with carpal flexural contracture deformities treated with rest alone or with rest and bandaging.

Animals: 47 dogs (75 joints).

Procedures: Medical records of dogs with unilateral or bilateral carpal flexural contracture deformities were reviewed, and dogs were grouped according to deformity severity grade (graded on a scale from 1 to 3) at the time of diagnosis.

Clinical outcomes of double pelvic osteotomies in eight dogs with hip dysplasia aged 10-28 months.

Objective: To report the short-term outcome of double pelvic osteotomy (DPO) in dogs with canine hip dysplasia ≥10 months of age.

Study Design: Case series.

Animals Or Sample Population: Eleven hips in eight dogs aged between 10 to 28 months.

Radiographic Recognition of Tarsal Malformation in 8- to 9-Week-Old Bernese Mountain Dogs.

Introduction:  Tarsal malformation is a skeletal malformation of unknown aetiology associated with a variety of morphologic changes to the tarsal and metatarsal bones of the dog.

Objective:  The aim of this study was to determine if early diagnosis and prevalence of tarsal malformation could be obtained at approximately 8 to 9 weeks of age in multiple litters of Bernese Mountain dogs.

Methods:  A prospective study of 51 Bernese Mountain dog puppies were evaluated from 12 litters in northern Italy.

Good Inter- and Intra-Observer Reliability for Assessment of Radiographic Femoral and Tibial Frontal and Sagittal Planes Joints Angles in Normal Cats.

Objective:  The aim of this study was to evaluate the inter- and intra-observer reliability of plain digital radiographs for assessing normal feline femoral and tibial joint reference angles in the sagittal and frontal planes.

Study Design:  This was a cadaveric radiographic anatomical study. that involved 20 short-haired domestic adult cats.

Computed tomographic localization of the deepest portion of the femoral trochlear groove in healthy dogs.

Objective: To validate a computed tomographic (CT) method to measure the femoral trochlear groove depth (FTGD).

Study Design: Cadaveric study.

Sample Population: Fifteen dogs, 26 femoral trochleae.

Simultaneous fluoroscopic-guided tibial plateau leveling and fracture reduction for the concurrent treatment of chronic cranial cruciate ligament tear and comminuted diaphyseal fracture of the tibia and fibula in a dog.

CASE DESCRIPTION A 12-year-old obese spayed female American Staffordshire Terrier was admitted for evaluation of acute non-weight-bearing lameness of the right pelvic limb attributed to motor vehicle-related trauma that occurred 2 hours previously. The owners reported a chronic, progressive weight-bearing lameness of the right pelvic limb secondary to a complete cranial cruciate ligament (CrCL) rupture that was diagnosed 6 months previously. They had declined surgery for CrCL repair because of the advanced age of the dog.

Computed Tomographic Trochlear Depth Measurement in Normal Dogs.

Objectives:  The main purpose of this study was to describe the relationship between patellar maximal craniocaudal thickness and femoral trochlear groove depth in normal dogs and to valuate the intra-observer or inter-observer variability of maximal trochlear depth and maximal patellar craniocaudal thickness using computed tomography.

Methods:  Trochlear groove depth and patellar maximal craniocaudal thickness of 40 limbs (20 dogs) were measured by three independent veterinarians using three-dimensional multiplanar reconstruction computed tomography images. The patellar maximal craniocaudal thickness/trochlear depth ratio was determined.

Comparison of Rotation Force to Maintain Acetabular Ventroversion after Double Pelvic Osteotomy and 2.5 Pelvic Osteotomy in a Canine Cadaveric Model.

Objective:  The aim of this article was to compare the force required to maintain the acetabular ventroversion after double pelvic osteotomy (DPO) and modified triple pelvic osteotomy (2.5PO).

Methods:  Unilateral DPO (group A) and unilateral modified DPO (group B = 2.

Prevalence, treatment and outcome of patellar luxation in dogs in Italy. A retrospective multicentric study (2009-2014).

Objective: To determine the prevalence of patellar luxation in dogs in Italy and its relation to signalment, the frequency and the type of postoperative complications and the outcome of treatment, and to compare the findings with those of other studies.

Materials And Methods: The medical records from four referral clinics were searched for dogs with orthopaedic disorders referred from 2009 to 2014. From these data, the records of dogs with patellar luxation were identified, and the signalment, age and body weight, grade, side and direction of patellar luxation, treatment, postoperative complications, and outcome were retrieved.

Contralateral bone widening and transfer for limb sparing in a cat.

Objective: To report on a novel surgical procedure to treat a long segmental tibial defect in a five-year-old 5 kg spayed female Main Coon cat using transverse distraction osteogenesis in the contralateral tibia to create a free autograft.

Methods: A long free bone segment was created from the cranial half of the normal tibia. A circular external fixator was constructed to give the segment 7 mm of cranial distraction.
