Stabilization of a proximal femoral physeal fracture in a filly by use of cancellous bone screws.

The research article discusses a successful case of treating a type-II fracture in the upper part of right femur in a two-month-old filly using cancellous bone screws. After facing a few challenges, positive long-term results were achieved, indicating early internal fixation can be a promising treatment for similar fractures.

Procedural Methods

• A two-month-old horse suffered from a Salter-Harris type-II fracture in the proximal portion of the right femur. Salter-Harris fractures are injuries to the growth plate region of children and adolescent bones.
• This fracture was reduced and stabilized using three cancellous bone screws. These screws are a type of fixation device, 6.5mm in diameter and 100mm long.
• The procedure was performed through a dorsal approach to the right coxofemoral joint, which means the surgery was done towards the back side of the joint connecting the hip and the thigh bone.

Challenges and Responses

• Eleven months post surgery, the screws were removed as the filly became lame in the affected limb, arguably experiencing discomfort or perhaps pain.
• Despite preventive measures, the surgical wounds suffered from dehiscence – a surgical complication where the wound reopens. The dehiscence was thought to be due to tightness of the skin in the coxal region.

Long-term Outcome and Implications

• Seven years following the original injury, the filly was capable of performing rigorous paddock exercise without exhibiting any signs of disability. In short, the filly had a return to normal function.
• The findings from the case study suggest that early internal fixation of proximal femoral physeal fractures in foals can offer a favorable long-term prognosis. This is significant for future veterinary practices as it presents an effective treatment method for similar cases.
