CASE DESCRIPTION: An 8-month-old American Bulldog was presented for assessment of bilateral thoracic limb lameness. Computed tomographic imaging revealed large, deep osteochondritis dissecans lesions in both humeral heads.
BACKGROUND: Suspension suture button fixation was frequently used to treat acromioclavicular joint (ACJ) dislocation. However, there were many studies reporting about complications and residual horizontal instability after fixation. Our study compared the stability of ACJ after fixation between coracoclavicular (CC) fixation alone and CC fixation combined with ACJ repair by using finite element analysis (FEA).
OBJECTIVE: To investigate clinical outcomes for dogs surgically treated for medial shoulder joint instability (MSI) by extracapsular stabilization with a prosthetic ligament. DESIGN Retrospective multicenter case series.
ANIMALS: 39 client-owned dogs.
OBJECTIVE: To report the use of computer-aided design software for virtual surgical planning and design of three-dimensional printed patient-specific osteotomy and reduction guides for facilitation of bilateral shoulder arthrodesis in a dog.
Osteochondrosis (OC) is common in large-breed dogs. According to the breeding guidelines of the Swiss kennel clubs, the shoulder joints are included in the radiographic screening for joint diseases in the Greater Swiss Mountain dog (GSMD) and the Border Collie (BC) since 1993 and 2003, respectively.
The aim of this study was to estimate the overall prevalence of humeral head OC in these 2 breeds in Switzerland based on the data of the Swiss National Dysplasia Committees. All radiographs were re-evaluated to assess single radiographic changes.
Radiography, magnetic resonance imaging (MRI), and ultrasonography are commonly used for diagnosis of shoulder osteochondrosis and osteochondritis dissecans (OC/OCD) in dogs, however there is a lack of published information on the relative diagnostic sensitivities of these modalities. The purpose of this prospective study was to compare diagnostic sensitivities of these modalities for detecting shoulder OC/OCD in a group of dogs, using arthroscopy as the reference standard.
OBJECTIVES: To assess the impact of stabilization method on the complication rate after lateral humeral condylar fracture (LHCF) repair.
STUDY DESIGN: Retrospective multicenter clinical cohort study.
ANIMALS: Dogs (n = 151) with LHCF.
To report thoracic limb alignment values in healthy dogs; to determine if limb alignment values are significantly different when obtained from standing versus recumbent radiographic projections.
Prospective cross-sectional study.
Labrador Retrievers (n = 45) >15 months of age.
To report short and medium term outcomes, and complications, in dogs treated for rupture of the lateral glenohumeral ligament (LGHL) with a novel, arthroscopically assisted technique.
Retrospective case series.
Dogs (n = 10) with LGHL injury.
Introduction: Partial resurfacing of the humeral head has been reported in humans to treat humeral osteochondritis dissecans. The aim is to describe a custom-made humeral resurfacing prosthesis for treatment of severe humeral head osteochondritis disse-cans in a dog. Case report: A seven-month-old female entire St. Bernard dog was presented with a 10 week history of severe left thoracic limb lameness. Radiography, arthroscopy and magnetic resonance imaging confirmed an extensive osteochondritis dissecans lesion affecting the caudal, medial and central regions of the humeral head.
