Objective:
To report the technique and the outcome for the repair of pelvic fractures in cats using external skeletal fixation (ESF).
Study Design:
Retrospective case series.
Animals:
Client-owned cats (n = 125).
Methods:
Medical records of cats with pelvic fractures, treated with an ESF between June 2001 and June 2009, were reviewed. Preoperative, immediate postoperative, and more than 4 weeks' postoperative radiographs were compared. Clinical examination was performed 4 to 9 weeks following surgery. Longer term follow up (4 to 80 months) was conducted by client questionnaire.
Results:
No intraoperative complications occurred. There was no change in the pelvic canal width observed on follow-up radiographs (p = .16). Implant loosening was noted on follow-up radiographs in 16/125 (13%) of cases, and 67/803 (8%) pins were palpably loose at the time of frame removal. The mean time to frame removal was 37 ± 9 days. No long-term complications were reported. Long-term mean mobility score was 95 ± 5 and median lameness was 0 (range: 0-2).
Conclusion:
An ESF may be successfully applied for the stabilization of various pelvic fractures in cats.
Clinical Significance:
The application of an ESF for the management of pelvic fractures in cats provides good outcomes.
