Long-term Outcome and Progression of Osteoarthritis in Uncomplicated Cases of Cranial Cruciate Ligament Rupture Treated by TPLO in Dogs
Authors: Masakazu Shimada, Nichika Mizokam, Tom Ichinohe, Nobuo Kanno, Shuji Suzuki, Takuya Yogo, Yasuji Harada, Yasushi Hara

The object of this study is to evaluate the long-term outcome of hind limb weight-bearing function and progression of stifle osteoarthritis (OA) after tibial plateau leveling osteotomy (TPLO).

Groups were classified by the degree of cranial cruciate ligament (CrCL) damage and presence or absence of medial meniscus damage as macroscopically evaluated during surgery. Weight-bearing function was assessed via the peak vertical force (PVF), and OA progression was assessed via the radiographic OA score (OAS) preoperatively and 1, 3, 6, 12, 18, 24, and 36 months postoperatively.

Locking Plate Fixation for Canine Acetabular Fractures
Authors: Piana F, Solano M, Kalff S, Yeadon R

OBJECTIVE: The aim of this study was to document application of locking plates for stabilization of acetabular fractures along with complications and clinical outcomes. We hypothesized that complications and clinical outcomes would be comparable to historical reports using non-locking plate and screw constructs.

Authors: Jenkins PL, James DR, White JD, Black AP, Fearnside SM, Marchevsky AM, Miller AJ, Cashmore RG

OBJECTIVE: To assess the medium- to long-term radiographically confirmed outcomes in juvenile dogs with hip dysplasia (HD) that did and did not undergo double pelvic osteotomy (DPO).

STUDY DESIGN: Retrospective case-controlled.

Coxofemoral Joint Luxation in Dogs Treated with Toggle Rod Stabilization: A Multi-Institutional Retrospective Review with Client Survey
Authors: Trostel CT, Fox DB

Coxofemoral luxation is the most common type of joint luxation observed clinically in dogs.

This retrospective study determines the complications and outcomes of open reduction and internal fixation of coxofemoral luxations using a toggle rod stabilization in 58 dogs. The purpose of the study was to compare the results with previous studies to ascertain commonalities and differences.

Authors: Mitchell MM, Hudson CC, Beale BS

OBJECTIVE: To compare femoral stem subsidence and determine contributing factors in dogs undergoing total hip replacement (THR) with the traditional BFX, collared BFX, and BFX lateral bolt stems.

STUDY DESIGN: Retrospective radiographic study.

Authors: Castelli E, Schmierer PA, Pozzi A.

OBJECTIVE: To describe the application of a custom acetabular prosthesis (CAP) for total hip replacement (THR) in a dog 20 months after femoral head and neck ostectomy (FHNO).

Authors: Kawarai Y, Orita S, Nakamura J, Miyamoto S, Suzuki M, Inage K, Hagiwara S, Suzuki T, Nakajima T, Akazawa T, Ohtori S.

We investigated the efficacy of duloxetine on hyperalgesia, histopathological and radiographic findings, pain-related sensory innervation of dorsal-root ganglia (DRG), and spinal changes in a rat model of induced hip osteoarthritis (OA).

Authors: Ulfelder EH, Hudson CC, Beale BS

OBJECTIVE: To compare distraction index (DI) with hip arthroscopy findings in juvenile dogs with hip dysplasia undergoing unilateral or bilateral double pelvic osteotomy (DPO).

STUDY DESIGN: Retrospective case series.

ANIMALS: Twenty dogs (36 hip joints).
