Nine cats with femoral comminuted fracture were repaired using V-shaped pins and wires. The advantage of this method is to reduce the fractured femur in the early course of operation to prevent shortening of the femoral length. Furthermore, patients could bear weight on the affected limb in the early stage of postoperative period. On radiography, satisfactory bone union were seen at 6 to 8 weeks (mean : 8.4 weeks) after surgery. It was concluded that the technique using the V-shaped pin and wire would be one of the useful methods for femoral diaphyseal comminuted fractures in cats.
The left proximal humerus of the 2 years-old female Great Pyrenees had swelling and lameness. In histopathologic examination, it was diagnosed as poorly differenciated osteosarcoma. The patient treated with amputation of the foreleg including scapula and cisplatin (total dose : 420 mg/m2) had no metastasis over seven years and four months, and was obtained long-term remission.
Two cats with mandibular swellings were histologically diagnosed as squamous cell carcinoma. No soft tissue lesion was observed in the oral mucosa, and mandibular radiographs showed considerable bone proliferation. These features differed from that of common feline oral squamous cell carcinoma in which ulceration of the oral mucosa and severe bone resorption were observed. In either case, hemimandibulectomy was performed, and there was no recurrence and metastasis for over one year. From these results, better clinical outcome may be expected in cats with oral squamous cell carcinoma with localized bone proliferation.
