Summary
This study reports on a rare humeral head-split fracture in two young dogs, presenting as chronic lameness. Conservative management showed positive short-term outcomes for this unusual Salter-Harris type IV fracture.
Area of Science:
- Veterinary Orthopedics
- Canine Skeletal Pathology
Background:
- Chronic lameness in skeletally immature dogs can stem from complex fractures.
- Proximal humeral fractures are uncommon in young animals.
Observation:
- Two young female dogs presented with chronic thoracic limb lameness.
- Radiographs revealed fissuring of the caudal humeral head, indicative of an incomplete Salter-Harris type IV fracture.
- A unique 'Enoki-mushroom-like' fragment and secondary neoarthrosis were noted.
Findings:
- Humeral head-split fracture is a rare injury pattern in skeletally immature dogs.
- Conservative management yielded reasonable short-term results in these cases.
Implications:
- Early detection and surgical intervention's role in humeral head-split fractures requires further investigation.
- Understanding this fracture pattern is crucial for veterinary orthopedic diagnosis and treatment planning.

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
