Open reduction and stabilisation of coxofemoral joint luxation in dogs and cats, using a stainless steel rope inserted via a ventral approach to the hip joint

Abstract

Open reduction and stabilisation of coxofemoral joint luxation was made via a ventral approach to the hip joint in dogs and cats, using a transarticular stainless steel rope. A feature of the procedure is transarticular penetration of the rope from the pelvic cavity to the femoral neck by guidance with a guide wire which was previously inserted from the femoral neck into the pelvic cavity and by detection of the guide wire in the pelvic cavity by use of forceps connected to an alarm-ohmmeter. Forty-seven animals (37 dogs and 10 cats) with acute and simple coxofemoral luxation were treated and postoperatively maintained in cage rest without external fixation. Most of the animals regained an almost normal gait within several days.

Toggle rod stabilisation of coxofemoral luxation in 14 cats

“…If closed reduction is not possible or the hip remains unstable, open reduction and stabilisation are indicated. Several surgical techniques have been described in cats including primary capsular repair, De Vita pinning, iliofemoral suture, rectus femoris origin suture, fascia lata loop stabilisation, trochanteric transposition, transarticular stainless steel rope, transarticular pinning and toggle rod fixation (Bennett and Duff 1980, Hammer 1980, Duff and Bennett 1982, Wildgoose 1983, Basher 1986, Bjerring Mehl 1988, Lubbe and Vestraete 1990, Meij and Hazewinkel 1992, Kawamata and others 1996, Moores 2006, Sissener and others 2009, Cetinkaya and Olcay 2010). Femoral head and neck excision arthroplasty (FHNEA) and total hip replacement can be used as salvage procedures when other techniques fail (Gendreau and Cawley 1977, Berzon and others 1980, Liska 2010, Off and Matis 2010, Witte and others 2010).…”

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 .…”

Hip joint

“…All methods of treatment bear some risk for reluxation, and conclusive evidence on which of the methods is best is lacking. Reluxation rates range around 10-20% for most techniques (23,29,30). Internal fixation of the luxated hip joint with suturing of the joint capsule and an iliofemoral suture technique or transarticular pinning are the techniques preferred by the authors.…”

“…These include suturing of the joint capsule, prosthetic capsular enhancement, De Vita pinning, transarticular pinning, and an iliofemoral suture technique (21, 22, 25, A B [27][28][29]. A technique using a stainless-steel rope, similar to toggle pinning but inserted via a ventral approach to the hip joint, was also described (30). All methods of treatment bear some risk for reluxation, and conclusive evidence on which of the methods is best is lacking.…”
