Clinical Trial: Evaluation of Partial Amputation in Dogs

Overview of the study

Alt Text

The purpose of this study is to determine outcomes associated with partial forelimb amputation and prosthetics in canine patients. Dogs with pathology of the lower forelimb (to the level of the wrist) that require a limb amputation may be eligible for enrollment in this study. Participation in this study requires several weekly rechecks followed by monthly recheck visits for the first six months, a single recheck  at nine months, and a single recheck at 12 months. Your dog will be required to wear an activity-monitoring collar and we will ask you to fill out several questionnaires. The study requires you to pay the cost of a regular amputation ($2,000), however, all additional and subsequent costs related to the study will be covered by the research fund. Additional costs covered by the study include the extra cost of the partial amputation surgery, the prosthetic device, and all rechecks and aftercare associated with the prosthetic device for the duration of the study.

Is there any danger to my dog?

There is no significant danger to you or your dog associated with the partial amputation or prosthetic device. The most common problem encountered is skin sores associated with wearing the prosthetic device. There is also a change your dog will not adjust to the prosthetic device requiring a full limb amputation.

*If your dog is suffering from neoplasia (cancer), there is a risk of incomplete removal of the cancer which may be avoided by full limb amputation.

There is danger associated with anesthesia and the amputation surgery – however, there is no additional danger associated with the partial amputation compared to a full limb amputation. Major risks associated with anesthesia/partial limb amputation are the same as for full limb amputation, however, the procedure is less invasive and involved. Major risks include bleeding, infection, anesthetic complications, including death, as explained by your clinician. Anesthesia and limb amputation will be performed the same as CSU-VTH standard procedures.

Who is eligible?

Dogs with disease or trauma that requires amputation are eligible. The disease must be limited to the lower limb of the front leg so that it is possible to amputate at the level of the mid-radius to allow for attachment of the prosthesis.

Dogs and their owners must live within reasonable driving distance from the CSU-VTH to allow for the regular recheck schedule.

Not all dogs with lower-limb disease will be eligible and must be evaluated prior to enrollment in this study.
