Prospective evaluation of pancarpal arthrodesis for carpal injuries in working dogs in New Zealand, using dorsal hybrid plating

Abstract

AIM: To determine whether working dogs in New Zealand with carpal injuries and treated with unilateral pancarpal arthrodesis (PCA), using a dorsal hybrid-plating method, are able to return to satisfactory working ability. METHODS:Fourteen working dogs presented to the Veterinary Specialist Group (VSG) and the Massey University Veterinary Teaching Hospital (MUVTH) with carpal injuries were prospectively treated using dorsal hybrid plating. Dogs were eligible if actively involved in farm, hunting or police work. Dogs had a standardised PCA surgical procedure performed, and similar instructions for post-operative care were provided. Dogs were re-evaluated clinically and radiographically at 6 weeks, 6 months, and 12 months after surgery. A questionnaire was completed by 12 owners, to assess each dog's working ability. RESULTS:Twelve months following arthrodesis, 10/12 (83%) dogs could perform most or all duties normally. Eleven owners (92%) reported that the result of the surgery met their expectations, and nine owners (75%) were very satisfi ed with the outcome of the surgery. No owners were disappointed or very disappointed with the surgical outcome. Post-operative complications requiring surgical removal of the implant occurred in three (25%) dogs. CONCLUSIONS:Unilateral PCA using a standardised surgical procedure and dorsal hybrid plating of carpal injuries has a good prognosis for working dogs in New Zealand to return to work. CLINICAL RELEVANCE:These results may allow veterinarians to provide a more accurate prognosis to owners of working dogs that have debilitating carpal injury

Retrospective Comparison of Titanium Hybrid Locking Plate with Stainless Steel Hybrid Dynamic Compression Plate for Pancarpal Arthrodesis: 23 Dogs

“…In our cohort, the proportion of cases diagnosed with carpal hyperextension injury is consistent with previous studies. 3,8,10 It is unknown if different diagnoses contribute to different outcomes or complications related to PCA. Plate MCov may affect screw-related complication.…”

“…Following screw sequences were at the surgeon's descretion. 8,10 inflammatory drugs for 10 days. All owners were instructed to restrict their pet's activity for a period of 6 weeks followed by slow return to activity.…”

“…Although there have been numerous retrospective studies of the outcome of PCA in dogs using a variety of implants, 1 3 4 6 7 8 9 10 11 12 14 comparison of fixation by plates with conventional cortex screws with plates fixed with locking screws is lacking. The purpose of this study was to (1) compare the implant characteristics (metacarpal coverage [MCov], metacarpal width occupied by screw diameter percentage and carpal arthrodesis angle) of titanium hybrid locking plates to stainless steel hybrid dynamic compression plates (HDCP) for PCA; and (2) compare complication rates and outcomes between these two implants.…”

“…6 Despite this, dorsal plating provides adequate support for osseous union to occur. 2 3 6 7 8 9 10 Dorsal plating for the stabilization of PCA in dogs was first described using dynamic compression plates. 11 Some of the reported complications with using the dynamic compression plate for PCA were excessive plate thickness over the metacarpal bones inhibiting soft tissue wound closure, and relative oversizing of metacarpal screws causing metacarpal bone fractures.…”
