Short-Term Clinical Assessment of Hip Hemi-Arthroplasty in 11 Dogs.

Objective:  The aim of this study was to assess the short-term clinical outcome in dogs following a hip hemi-arthroplasty for the treatment of primary pathological disorders of the hip and as a salvage procedure following failure of the cup component of a total hip replacement.

Study Design:  Medical records of dogs that had a unilateral hip hemi-arthroplasty performed between 2015 and 2020 were reviewed. Data collected included follow-up orthopaedic examinations performed at 0, 2, 8 and 52 weeks postoperatively, pelvic radiography at 0, 8 and 52 weeks postoperatively and an owner questionnaire (Helsinki chronic pain index [HCPI]).

Surgical management and long-term outcome of dogs with cervical spondylomyelopathy with an anchored intervertebral titanium device.

Objective: To assess the short- and long-term outcome of an anchored intervertebral titanium device (C-LOX) for the treatment of 10 dogs with disc-associated cervical spondylomyelopathy (DACSM) and 1 dog with osseous-associated cervical spondylomyelopathy.

Design: Retrospective case series.

Methods: Dogs were included if they were diagnosed with either DACSM or osseous-associated cervical spondylomyelopathy via myelography with or without advanced imaging and underwent surgical distraction and stabilisation of the affected intervertebral disc with a C-LOX implant.

Comparison of gait and pathology outcomes of three meniscal procedures for induction of knee osteoarthritis in sheep.

Objective(s): Meniscectomy (MX) of sheep induces a well-established animal model of human osteoarthritis (OA). This study compared the clinical (lameness) and pathological outcomes of unilateral, complete medial MX vs two less traumatic and more easily performed meniscal destabilisation procedures.

Methods: Four-year old wethers (n = 6/group) underwent sham operation, cranial pole release (CPR), mid-body transection (MBT) or total MX of the medial meniscus.

Effect of oral antigen and antibody exposure at birth on subsequent immune status. A study in neonatal pigs.

Background: The purpose of this work was to investigate the effects of early low-level exposure to either antigen or antibody alone on subsequent immune responses in entirely immunologically naïve animals. This is impossible in species with a permeable placenta such as rodents or humans, where both antigen and antibody can be transferred in utero. It is, however, possible in pigs, due to the impermeable placenta of the sow.
