Coxofemoral Luxation

Question 1

Kieves, Vet Surg, 2014:
Hip toggle stabilization using the TightRope system

1. Complication rate?
2. Reluxation rate?
3. Outcomes?

Answer 1

Kieves, Vet Surg, 2014:

1. 12% complication rate
2. 6% reluxation rate
3. 88% excellent outcome (no lameness), 12% good outcome

Question 2

Kraska and Jackson, Vet Surg, 2018:
Hip toggle stabilization

1. Failure rate?
2. Most common method of failure?
3. Which construct withstood the greatest load to failure?

Answer 2

Kraska and Jackson, Vet Surg, 2018:

1. 83% failure rate
2. Suture breakage at the toggle-suture interface was the most common method of failure due to friction and fraying
3. The construct with OrthoFiber #5 (braided UHMWPE suture) passed straight through the toggle rod eyelet withstood the greatest load to failure

Question 3

Helmick, VCOT, 2018:
Hip toggle stabilization

What % of hips had cartilage damage when the acetabulum was drilled via the femoral tunnel vs drilled independently?

Answer 3

Helmick, VCOT, 2018:

Cartilage damaged occurred in 38% of the hips in which the acetabulum was drilled via the femoral tunnel, and 0% of the hips in which the acetabulum was drilled independently

Schlag, JAVMA, 2019:
Closed reduction and Ehmer sling application

1. Reluxation rate?
2. What % developed soft tissue injuries secondary to sling use?
3. Success rate?
4. Complication rate?

Answer 4

Schlag, JAVMA, 2019:

1. 44% reluxation rate
2. 50% developed soft tissue injuries secondary to sling use
3. Low success rate
4. High complication rate
