The canine scapula is a large, flat bone composed of a body with a longitudinally running, flat spine; a neck; and the glenoid, or articular surface. The flatness of the body and spine and lack of medullary cavity make fixation with standard intramedullary rods and pins impossible. Because of its prominence at the ends of the scapular spine, the acromion can fracture or avulse. The acromion process does not lie below the level of the shoulder joint in a normal animal. The neck is more oval in the cross section and has sufficient medullary bone to accept pins or screws. The glenoid surface is a shallow bony concavity that articulates with the humeral head. The cranial margin of the glenoid forms the supraglenoid tubercle (scapular tuberosity), the origin for the biceps brachii muscle. In the dog, the coracoid process is insignificant ( and ).

Meanwhile, I tried to find other posts by Buddy's people about whether or not they went with the full scapular amputation but unfortunately I can't find any. I will say that the large majority of people do get the entire scapula removed. Leaving a partial is only useful if you're considering a prosthetic (and if you are, be sure to consult with a company like before the surgery to ensure he's a good candidate for a prosthesis. Most dogs who have a partial amp encounter major healing problems and end up getting another surgery to remove the remaining bone. Hope this helps! 17.

A 14-month-old golden retriever was presented with progressive right front limb lameness of 1.5 months' duration caused by a large spherical mass in the right scapula. Radiographic examination was consistent with skeletal neoplasia, showing a distinctive area of osteolytic and osteogenic activity, adjacent soft tissue invasion and metastatic lesions in the anterior lung fields. The histopathologic examination established the diagnosis of minimally productive, osteoblastic, grade III osteosarcoma. Both scapular osteosarcomas and osteosarcomas in very young dogs are rarely described; to the best of our knowledge, scapular osteosarcomas have not been described at such a young age previously.A 14 month-old, male entire, golden retriever weighing 25 kg was presented to a private clinic in Limassol, Cyprus with a history of progressive right forelimb lameness of 1.5 months' duration. Upon clinical examination, a large, spherical mass, measuring approximately 30 cm in diameter, concerning the right scapula as well as generalized muscle atrophy of the limb were observed. On palpation, the mass was hard, poorly demarcated, solid, and had irregular and rough surface, while the shoulder was painful when passively pulled. The dog was alert but its temperature was remarkably high (40.7 C). Additionally, mild coughing was easily reproduced during light exercise and exposure to stress, and mild abnormal sounds in the lung were noticed during thorax auscultation.Osteosarcoma (OS) is the most common primary bone tumour in the dog. In general, it is an aggressive malignancy of osteoblasts with a high rate of metastasis. 5,18,20 According to the World Health Organization classification of bone and joint tumors, 17 an OS is a primary malignant neoplasm of mesenchymal origin that gives rise to a variety of patterns but always includes the production of bone by malignant osteoblasts. Its biological behaviour seems to vary depending on location, age or breed. 5,18,20 Although there is a broad range in the age of onset, OS is a disease that mostly occurs in middle-aged to older dogs, with a median age of 7 years. 2,5,18,20 The metaphyseal region of the long bones is the most common primary site. 5,18,20 This paper reports a case of a scapular osteosarcoma in a 14-month old dog, thus presenting a case that has arisen both in an uncommon location and in an uncommonly young age.In chest radiographs, metastatic lesions were evident within the anterior lung fields (Figure 2). At this point, malignant neoplasia of the scapula with pulmonary metastases was diagnosed and the owner of the dog was informed of the poor prognosis.
