Hip toggle stabilization using the TightRope® system in 17 dogs: technique and long-term outcome

Area of Science:

• Veterinary Orthopedics
• Surgical Techniques

Background:

• Coxofemoral luxation is a common orthopedic emergency in dogs.
• Traditional repair methods can have variable success rates.
• The TightRope® system offers a novel approach to prosthetic ligament stabilization.

Purpose of the Study:

• To detail the surgical technique for a modified hip toggle stabilization using the TightRope® system.
• To evaluate the long-term clinical outcomes and owner satisfaction following this repair method.

Main Methods:

• A retrospective case series of 17 dogs undergoing coxofemoral luxation repair with the TightRope® system.
• Medical records and radiographs were reviewed from July 2008 to July 2010.
• Long-term follow-up (≥12 months) included owner telephone interviews and objective gait analysis in 6 dogs.

Main Results:

• Follow-up averaged 24 months (range, 12-43 months) for 17 dogs.
• Objective gait analysis in 6 dogs revealed equal pelvic limb use.
• Owners reported good to excellent limb function and no pain in living dogs; no osteoarthritis progression was noted on radiographs.

Conclusions:

• Modified hip toggle stabilization with the TightRope® system provides a favorable clinical outcome for coxofemoral luxation.
• This technique demonstrates high owner acceptance and satisfaction.
• The TightRope® system serves as an effective prosthetic ligament for hip stabilization.
