OBJECTIVES: This study aimed to describe a stress radiography to detect medial glenohumeral ligament rupture and to investigate the repeatability and reproducibility of this test.

Authors: Murphy SC, Egan PM, Fitzpatrick NM.

OBJECTIVE: To report the outcome of dogs with large, caudocentral, osteochondritis dissecans (OCD) lesions of the humeral head treated with synthetic osteochondral resurfacing (SOR) implants.

STUDY DESIGN: Retrospective case series.

OBJECTIVES: To describe the range of motion and clinical stability of the feline shoulder following experimental injury and repair using a prosthetic suture technique.

OBJECTIVE: To describe a minimally invasive surgical technique for the treatment of comminuted humeral bicondylar (also known as T-Y) fractures in dogs and report outcome in 3 cases.

OBJECTIVE: This study evaluated the proficiency in executing closed, fluoroscopic-assisted reduction of unicondylar humeral fractures. The following were hypothesised: experienced surgeons would be highly successful in performing closed reduction; body weight, time to surgery and surgeon experience would influence the reduction method; and the reduction method would not affect technical aspects of the repair.

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.
