[Diagnostic procedures and treatment of a ventromedial coxofemoral luxation in sheep - Surgery and open reposition of a ventromedial coxofemoral luxation with a toggle-pin and iliofemoral sling fixation].

A 2.5-year-old female Valais black-nosed sheep was referred to the University Clinic for Ruminants at the University of Veterinary Medicine Vienna, with a history of sudden lameness after shearing. The sheep showed a moderate mixed lameness of the right hind limb, the hip joint area was painful on palpation; the pelvic limb was presented as stretched as possible. After the clinical examination, the suspected diagnosis of a right-sided hip joint dislocation was made, which was subsequently confirmed radiologically (luxatio ossis femoris dextra to caudoventral and medial). An open, manual reposition was performed under general anesthesia. A toggle pin was used as a prosthetic ligament replacement for the femoral head ligament, further stabilization was achieved by means of an iliofemoral loop fixation within the fascia of the gluteal muscles.The movement possibilities of the sheep during the postoperative healing phase were severely restricted and 8 weeks of stall rest were ensured. The healing process was uncomplicated. Telephone enquiry 6 months following the surgical intervention revealed that the sheep was free of lameness, kept up with the herd, and displayed a normal general condition.The success of surgery and the use of the procedure in livestock practice is limited by the necessity of rapid intervention after the trauma has occurred, the willingness of the animal owner to bear the costs associated with the operation under general anesthesia as well as to ensure the long post-operative follow-up care with controlled restriction of movement.
