Toggle rod stabilisation of coxofemoral luxation in 14 cats

Abstract

To describe the surgical technique and to report outcomes in cats with coxofemoral luxation treated with open reduction and toggle rod stabilisation. Retrospective study of cats with coxofemoral luxation stabilised via the toggle rod method. Short-term follow-up included clinical examination and radiographs. Long-term follow-up was via owner questionnaire. Fourteen cats were included. All of the cats had reported unilateral craniodorsal hip luxation. Nine cats (64·3%) had additional orthopaedic injuries. Luxations were stabilised with a 3·2-mm toggle rod (2·7-mm toggle rod in one cat) and two loops of four-metric polydioxanone (five-metric polydioxanone in one cat and three loops of four-metric polydioxanone in two cats). Success rate, in terms of maintenance of reduction, was 86%. Reluxation occurred in two cats (14%), both of which had multiple limb injuries. Eleven owner questionnaires (mean follow-up time 15·5 months) reported a functional outcome of "very good" to "excellent". Although the diameter of the pelvic canal was reduced by the presence of the toggle rod (mean narrowing 16.2%), none of the cats had defaecatory issues. 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.
