Toggle rod stabilisation of coxofemoral luxation in 14 cats

Abstract

Toggle rod stabilisation is an effective method for the treatment of coxofemoral luxation in cats. Injuries to multiple limbs may be a risk factor for reluxation.

Minimally invasive technique for coxofemoral luxation stabilisation using transarticular toggle system: a cadaveric study

“…Various techniques for open reduction and stabilisation of the hip have been described, including De Vita pinning ( De Vita 1952, Douglas 2000, placement of extracapsular sutures ( Martini et al . 2001 ), tenodesis of the deep gluteal muscle ( Rochereau & Bernardé 2012 ), transarticular pinning ( Sissener et al 2009 ), flexible external fixation ( McLaughlin & Tillson 1994 ) and toggle rod stabilisation ( Lawson 1965, Ash et al 2012, Pratesi et al 2012. In the transarticular toggle rod stabilisation technique, which is a successful method to stabilise coxofemoral luxation in dogs and cats ( Ash et al 2012, Pratesi et al 2012, the round ligament of the femur head (teres ligament) is restored.…”

The advantages of this method include isometric coxofemoral stability and relatively low re-luxation rates, reported to be 5 % in one study (Kieves et al 2015).…”

Mechanical analysis of suture attachment methods in toggle suture constructs

“…Our mechanical testing set‐up, based on a prior bench top mechanical analysis of toggle suture constructs, introduced the variable of suture attachment method to the toggle. The 1/8‐in toggle rod is the most commonly used implant size reported in the veterinary literature for hip luxation repair . The mean weight reported in the literature for dogs with traumatic coxofemoral luxation and subsequent repair ranges from 15 kg to 29 kg, and the 1/8‐in toggle rod is the manufacturer‐recommended implant for dogs of this size .…”

“…Stabilization of a coxofemoral luxation with a toggle suture construct is one of the more common surgical methods used for hip luxation repair and has a success rate of 86%‐89% . Among cases that fail, the most common reported complication after reduction and stabilization with a toggle rod is breakage of the suture and reluxation of the coxofemoral joint .…”

“…2,4,9,12 Stabilization of a coxofemoral luxation with a toggle suture construct is one of the more common surgical methods used for hip luxation repair and has a success rate of 86%-89%. 3,14 Among cases that fail, the most common reported complication after reduction and stabilization with a toggle rod is breakage of the suture and reluxation of the coxofemoral joint. 3,4,15,16 Analysis shows that construct failure typically occurs in 1 of 3 ways: toggle deformation, suture breakage away from the toggle and most commonly, suture breakage at the toggle-suture interface.…”
