This study details a West Highland White Terrier with craniomandibular osteopathy, presenting with carpal deformities and mandibular/calvarial thickening. Surgical intervention corrected the limb deformities, confirming the diagnosis.
Area of Science:
- Veterinary Medicine
- Canine Orthopedics
- Comparative Pathology
Background:
- Craniomandibular osteopathy (CMO) is a non- संक्रामक, inflammatory bone disease affecting the mandible and calvarium in young dogs.
- Early diagnosis and intervention are crucial for managing CMO and its associated orthopedic complications.
Observation:
- A four-month-old West Highland White Terrier presented with bilateral angular carpal deformity (20° valgus) and thickened distal ulnas.
- Radiographs revealed periosteal new bone formation on the ulna, central physeal closure, humeroulnar subluxation, and characteristic changes in the calvarium and mandible.
Findings:
- Radiographic and histological findings confirmed craniomandibular osteopathy.
- The dog exhibited clinical signs of pain on mandibular palpation and elbow joint manipulation.
Implications:
- Bilateral ulna ostectomy successfully corrected the angular limb deformity and elbow subluxations.
- This case highlights the importance of recognizing and managing the orthopedic manifestations of CMO in young dogs.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
