Treatment of a coxofemoral luxation in a pony using a prosthetic capsule technique.
Abstract: To report open reduction and joint stabilization using a prosthetic capsule technique for treatment of a craniodorsal coxofemoral luxation in a lightweight pony. Methods: Clinical report. Methods: Pony stallion (8 years old, 113 kg). Methods: A craniodorsal approach to the coxofemoral joint was performed under general anesthesia. After open reduction, a prosthetic capsule technique was used. Four 3.5 mm self-tapping cortical anchor screws were implanted: 2 screws were inserted above the cranial aspect of the dorsal acetabular rim, and 2 screws were inserted into the femoral neck. Subsequently, a #5 USP ultra-high molecular weight polyethylene suture was placed through these anchor screws in figure-8 fashion to serve as a prosthetic capsule. Routine closure and a medial patellar desmotomy completed the surgical procedure. Postoperatively, the pony was cross tied for 4 weeks to prevent it from lying down. Results: Neither short-term nor long-term complications occurred and the pony was sound at the follow-up examination performed 15 months postoperatively. Conclusions: A prosthetic capsule technique can be used successfully to stabilize the coxofemoral joint after open reduction of a craniodorsal luxation in a lightweight pony.

The research article discusses a successful procedure for treating a craniodorsal coxofemoral luxation in a pony using a novel prosthetic capsule technique. The pony recovered without any short or long-term complications.
Methodology
- The experiment was carried out on an 8-year-old pony stallion, weighing 113 kg.
- The primary surgery involved an open reduction approach—a process by which a dislocation or fracture is corrected—on the coxofemoral joint (where the hip meets the thigh) while the pony was under general anesthesia.
- A novel technique involving a ‘prosthetic capsule’ was used, as a central part of the procedure. The ‘capsule’ was constructed using four 3.5 mm self-tapping cortical anchor screws.
- Two of these screws were inserted above the cranial aspect of the dorsal acetabular rim (a part of the hip joint), and the remaining two were inserted into the neck of the femur.
- A type of suture made from ultra-high molecular weight polyethylene was fed through the anchor screws in a figure-8 pattern, creating the ‘prosthetic capsule’.
- Routine closure of the surgical site was performed and a medial patellar desmotomy—at surgical cut made to the medial patella ligament—was also performed.
- Post-surgery, the pony was prevented from lying down for four weeks as a precaution.
Results
- No short-term or long-term complications manifested from the operation.
- The pony had fully recovered and was in good health at the follow-up examination conducted 15 months later.
Conclusions
- The successful execution of this surgery suggests that the prosthetic capsule technique can be an effective means of stabilizing the coxofemoral joint following an open reduction of a craniodorsal luxation, at least for lightweight ponies.
- As with all invasive procedures, potential risks and complications should be carefully considered.
- Further investigations and trials would be essential to validate and quantify the overall success rate of this particular treatment technique.
