title: Treatment of a coxofemoral luxation in a pony using a prosthetic capsule technique.
abstract: OBJECTIVE
  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.
