Objective

To describe the technique for, and long-term clinical outcome of, a modified hip toggle stabilization using the TightRope® system for coxofemoral luxation repair.

Study Design

Retrospective case series.

Methods

Medical records (July 2008–July 2010) including radiographs (17 limbs) of dogs that had coxofemoral luxation repaired with the TightRope system were reviewed. Follow-up (≥12 months) was obtained by telephone interview of owners. Six dogs were available for re-evaluation, radiographs, and objective gait analysis.

Results

Follow-up (mean, 24 months; range, 12–43 months) by telephone interview was available for 17 dogs. Of these, 6 dogs were re-evaluated (mean, 7.5 months; median 12.5 months: range, 4–24 months) and had gait analysis. Mean duration of luxation before surgical intervention was 7.5 days (median, 7 days; range, 2–44 days). There was a single case of relaxation 27 months postoperatively. One dog died from non-surgical related circumstances. Objective gait analysis showed equal pelvic limb use in all 6 dogs available for re-evaluation. All owners of living dogs reported limb function as being good to excellent, and perceived that their dogs were pain free. Radiographs (mean, 7.5 months; median, 12.5 months; range, 4–24 months post surgery) of 6 dogs showed no progression of osteoarthritis in comparison to immediate postoperative radiographs.

Conclusions

Hip toggle with the TightRope system as a prosthetic ligament of the head of the femur produces a favorable clinical outcome with high owner acceptance.
