Treatment of a periarticular tibial fracture in a foal with a hybrid external fixator.

This research discusses a surgical treatment of a proximal tibial fracture (a type of leg fracture) in a 5-month-old foal using a hybrid external fixator (HEF), a device constructed from wires, half-rings, connecting rods, and screws. The research indicates that the treatment was successful, as the foal was able to bear weight immediately after the surgery and the HEF was removed after two months following confirmation of healing.

Methodology

• The study involved the treatment of a specific form of leg fracture, known as a right proximal tibial Salter-Harris type II fracture, in a 5-month-old male foal.
• The surgical procedure included an open surgical reduction, which involves a surgeon manually realigning the broken bone fragments.
• A Hybrid External Fixator (HEF) was used to stabilize the fracture. This HEF was constructed from wires, two half-rings, three half-threaded connecting rods, and Schanz pins (a type of orthopedic pin commonly used in external fixators).

Results

• The results of the procedure were immediately observable post-surgery. The foal had relatively good weight bearing, an indication that the stability provided by the HEF was effective.
• After 60 days, the HEF was removed. This decision was made following radiographic confirmation of healing. Radiographic imaging, or X-ray imaging, is regularly used to track the progress of bone healing after surgery.

Conclusions

• The study concluded that a Hybrid External Fixator is a viable option for the treatment of proximal tibial Salter-Harris type II fractures in a foal. This specific form of leg fracture is not uncommon in young horses, hence this finding is of particular relevance to veterinary practice.
• The research suggests that the HEF provides an effective method for stabilizing leg fractures in young horses, favorably suggesting it as a repair option for such injuries.
