Case Study #101603

Delenn's career as a competitive obedience dog had been put on hold because of a severe femur fracture that just wouldn't heal. In fact, rather than healing, the bone was disappearing. Dr. Greenwood knew the solution was to replace a part of Delenn's femur with an allograft from VTS.

VTS Case #101603

Patient Name: Delenn
Age/Sex: 7 years / Female
Weight: 18 lbs.
Breed: Sheltie

Condition: Femoral non-union with significant bone loss.
Treatment: Replacement of resorptive section with allograft segment and stimulation of bony fusion with Osteoallograft™ chips and demineralized powder.
Graft Types: Osteoallograft™ Fine Mix of Cancellous Chips and Demineralized Bone Powder and a Canine Metacarpal Segment.

Surgeon: Dr. Ken Greenwood
Clinic: Northlake Veterinary Specialists
Location: Clarkston, GA

Description of the Procedure


	Figure 1. This photo shows a detail of our Osteoallograft Fine Mix. The Fine Mix is perfect for packing into small areas.

	Figure 2. The segment of metacarpal (like the one shown here) was from the front paw of a much larger Mastiff.

	Figure 3. The image on the left shows the segment trimmed to size and secured in place with screws. Once secured, the Osteoallograft Fine Mix was combined with the patient's blood before packing into the surgical site (right).

	After 2 weeks of post-op recovery, the patient returned for a followup exam. The patient was bearing weight on the leg.

	Figure 4. Seven months after surgery, the patient was enjoying normal activity.

Pre- and Post-operative Radiographs


	Figure 5. The pre-op radiograph (left) shows the level of resorption that has caused the deformity. The post-op radiograph (right) shows the meta-carpal allograft secured in place with plate and screws.

	Figure 6. These post-op radiographs taken 5 months (left) and 7 months (right) show the allograft has fused very well with the patient's own bone.
