Objective To describe open reduction and surgical stabilization of a coxofemoral luxation in a pony using a modified toggle pin technique and prosthetic joint capsule reconstruction without osteotomy of the greater trochanter. Animal A 2-year-old Shetland pony with a bodyweight of 167 kg. Study design Case report. Methods Radiographic examination confirmed craniodorsal luxation of the left coxofemoral joint. An open reduction with the aid of a pulley system was performed. A toggle pin was inserted through a bone tunnel extending from the level of the femoral shaft through the femoral head and the center of the acetabulum for the pin to be positioned on the medial wall of the acetabulum. FiberWire was subsequently passed through the cranial and caudal aspects of the acetabulum as well as a transverse tunnel in the femoral neck in a figure of 8 to facilitate capsular reconstruction. The pony was placed in a sling for 8 weeks and gradually returned to normal activity over 2 months. Results Postoperative radiographic examination confirmed the position of the femoral head in the acetabulum with the implants in place. On 2-year follow-up the pony was sound at walk and trot. Conclusion A combined intra-and extra-articular stabilization technique for coxofemoral luxation in a pony resulted in successful long-term reduction and excellent outcome.
SummaryA 2‐day‐old female Warmblood foal (70 kg) presented with a closed, displaced Salter‐Harris type‐II fracture of the proximal physis of the left hind first phalanx. The fracture was repaired with four 4.5 mm cortical screws and a wire in a figure‐of‐8 pattern applied on the lateral and medial aspect of the phalanx, respectively. A 4.5 mm cortical screw was additionally inserted in lag‐fashion to engage the lateral metaphyseal spike. Three days postoperatively, medial and proximal displacement of the distal fracture fragment and implant infection were apparent and revision surgery was performed. Previous implants were removed and two 4.5 mm transphyseal cortical lag‐screws were placed in proximolateral–distomedial and dorsoproximal–plantarodistal direction across the physis and the fracture line. Postoperatively, the fracture healed rapidly and the implants were removed 6 weeks later. Nineteen months after implant removal, the horse did not show any sign of lameness, despite a shortening of the proximal phalanx compared to the contralateral limb. In cases of postoperative implant instability and infection, implant removal often becomes necessary. However, new implants cannot be placed safely in the previous location. To avoid this problem, this report describes an alternative approach for screw positioning in case of previous implant infection in a Salter‐Harris type‐II fracture of the proximal physis of the first phalanx.
