Combined intra-extra-articular technique for stabilisation of coxofemoral luxation

Abstract

This tape-technique enabled reinforcement of the acetabular roof which in turn increased the stability of the joint.

Hip Toggle Stabilization Using the TightRope® System in 17 Dogs: Technique and Long‐Term Outcome

“…Open reduction and stabilization of CFL is indicated when closed reduction fails, or in cases where immediate weight bearing on the luxated hip is necessary because of concurrent orthopedic injury in the contralateral limb. Many surgical techniques have been described for open reduction including intra and extra‐articular stabilization methods . Of the reported procedures, no single technique has proven superior to another in terms of technical ease, complication rates, or long‐term outcome.…”

“…When a closed reduction fails, or there are concurrent orthopedic injuries (pelvic fractures, intra‐articular fractures) that require immediate weight bearing, open reduction with stabilization, total hip arthroplasty, triple pelvic osteotomy or femoral head and neck ostectomy (FHO) is warranted. Numerous techniques for open reduction and stabilization of the hip have been described including capsulorrhaphy, DeVita pinning, placement of extracapsular sutures, tenodesis of the deep gluteal muscle, transarticular pinning, transposition of the greater trochanter of the femur, transposition of the sacrotuberous ligament, and toggle rod stabilization …”

Mechanical Analysis of Twelve Toggle Suture Constructs for Stabilization of Coxofemoral Luxations

“…Mechanically, the strength of repair after toggle rod fixation is comparable to other open techniques for stabilizing hip luxation . The biomechanical performance of the construct used in toggle rod fixation depends on the tensile strength of the suture material, the interaction of the suture material with the toggle rod, the pull out strength of the toggle rod, and the orientation of the toggle rod . A recent retrospective study reported 26% of a cohort of dogs had complications after stabilization of hip luxation with toggle rod fixation; 11% of these complications were re‐luxation of the stabilized hip joint .…”

Mechanical analysis of suture attachment methods in toggle suture constructs

“…The 1/8-in toggle rod is the most commonly used implant size reported in the veterinary literature for hip luxation repair. [14][15][16][17][18] The mean weight reported in the literature for dogs with traumatic coxofemoral luxation and subsequent repair ranges from 15 kg to 29 kg, 3,4,9,15,20,21 and the 1/8-in toggle rod is the manufacturer-recommended implant for dogs of this size. 22 OrthoFiber #5 was chosen for our testing construct on the basis of prior comparative analyses showing increased load to failure, decreased suture elongation, and increased stiffness compared with monofilament nylon leader line.…”
