A 26-week-old female Boerboel was referred for evaluation of progressive left thoracic limb lameness. Computed tomography and radio-graphic evaluation revealed radiolucency of the caudal region of the proximal humeral metaphysis, absence of the humeral head, and gross distortion of the glenoid. Given the severe glenohumeral deformation, arthrodesis of the left shoulder was performed using orthogonal locking bone plates, lag screw fixation, and bone grafting. Despite late implant failure, arthrodesis was successful in this case, and satisfactory limb function was restored. To the author's knowledge, this is the first report of a case of a focal developmental deficiency of the proximal humerus reported in a dog. © Schattauer 2012. Source

Objective: To report the signalment and clinical features of dogs with non-traumatic lateral patellar luxation and to report the complications and outcomes following surgery. Methods: A multicentre retrospective study was performed. Medical records were reviewed and the signalment, clinical features, and treatment of dogs presenting with lateral patellar luxation were recorded. In dogs treated surgically, the outcome and complications were investigated. Results: Sixty-five dogs (95 stifles) were included; 39 were male and median age at presentation was 10 months. Breeds were classified as small (n = 6), medium (n = 23), large (n = 27), and giant (n = 9). Lateral patellar luxation was classified as grade I (n = 14), II (n = 41), III (n = 29), and IV (n = 11). Conformational abnormalities were noted in 34 stifles; genu valgum was the most common (n = 28). Higher-grade luxation was associated with a younger age at presentation (p = 0.032) and genu valgum (p = 0.01). Surgery was performed on 58 stifles, 22 of which sustained one or more complications; 16 complications were managed conservatively, four with implant removal and six with revision surgery. Surgeon-assessed outcome was good or excellent in 47 of the 51 dogs available for review. Conclusions: Non-traumatic lateral patellar luxation is a disease of predominantly medium and large breed dogs. It has several similar clinical features and can be surgically treated in a similar manner to medial patellar luxation with similar types of complications and outcomes expected. © Schattauer 2014.

A two-year-old female neutered Whippet was referred for evaluation of progressive right pelvic limb lameness. Clinical examination revealed a fibrous band palpable along the cranial aspect of the quadriceps muscle group, and signs of discomfort on extension of the right hip. Computed tomography and ultrasonographic examination revealed mineralization of the tensor fascia lata muscle with enthesophytosis of its origin. Surgical exploration confirmed a fibrous band affecting the cranial border of the tensor fascia lata muscle. Resection of the band resulted in complete resolution of clinical signs. Histopathology was consistent with a fibrotic myopathy. To the authors' knowledge, this is the first case of a fibrotic myopathy affecting the tensor fascia lata muscle in the dog. © Schattauer 2013.
