Plain-English summary
A 9-month-old female German Shorthaired Pointer was brought in for limping on her right front leg and had a firm swelling on her forelimb that had been growing for two weeks. After two months of weight-bearing lameness, the vet used a special imaging test called computed tomography to diagnose a bone growth (osteochondroma) that was causing damage to her ulna (the bone in the forearm). The vet performed surgery to remove the affected bone and the growth. The dog recovered well and was sound at follow-up visits at 2, 16, and 45 weeks after the surgery, with no signs of the growth returning.

Abstract
OBJECTIVE: To describe the diagnosis, management, and outcome of a dog with a right distal radial osteochondroma that penetrated the ulna, causing expansile lysis and fracture. ANIMAL: A 9-month-old entire female German Shorthaired Pointer. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: The dog had a 2-month history of weight-bearing lameness of the right forelimb and a 2-week history of a progressively enlarging, firm swelling on the distolateral antebrachium. Computed tomography was used to characterize the lesion and for surgical planning. TREATMENT AND OUTCOME: A distal ulnar ostectomy removed the affected ulnar segment, and the radial osteochondroma was excised with rongeurs. The dog was sound at 2, 16, and 45 weeks postoperatively. Radiographs at 45 weeks showed a persistent ulnar ostectomy gap with irregular but smoothly marginated edges and focal cortical irregularity at the site of radial osteochondroma excision. There was no evidence of osteochondroma recurrence. CLINICAL RELEVANCE: This is a newly recognized presentation of an osteochondroma penetrating the cortex of an adjacent bone in a dog resulting in expansile lysis and cortical fracture. Computed tomography was important in diagnosis and surgical planning, and surgical treatment was successful in removing the osteochondroma and ulnar lesion. This case provides long-term radiographic and clinical follow-up after osteochondroma excision and contributes to the current knowledge on prognosis following osteochondroma excision in dogs.
