Abstract
Objectives The main aim of this study was to report the surgical technique, the complications
and the clinical outcomes of the mini-Tight Rope system (mini-TR) for a modified hip
toggle stabilization of coxofemoral luxation in cats.
Study Design A multicentre retrospective study.
Animals Thirty-two client-owned cats.
Methods Medical records (2009–2017) of cats, which underwent stabilization of a coxofemoral
luxation with the mini-TR and had at least a 3-month follow-up, were reviewed. The
femoral tunnel diameter, the use of one or two FiberWire loops, perioperative complications
and clinical outcomes were recorded. Follow-up information was obtained through clinical
and radiographic examinations and an owner questionnaire.
Results Thirty-two cats met the inclusion criteria. Concurrent injuries were present in 16
cats. A single or double loop mini-TR was used in 21 and 12 cats respectively. One
double loop (1/12 cats) and four single loop (4/16 cats) sutures failed. Moderate-to-severe
coxofemoral osteoarthritis developed in 14/27 cats. Owner questionnaires revealed
excellent clinical outcomes.
Clinical Significance Mini-TR with a double-stranded implant is recommended to decrease the risk of suture
failure. Osteoarthritis is common after open reduction of hip luxations.
Keywords traumatic coxofemoral luxations - modified hip toggle stabilization - feline coxofemoral
