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.

Femoral non-union with significant bone loss.
Replacement of resorptive section with allograft segment and stimulation of bony fusion with Osteoallograft™ chips and demineralized powder.
Osteoallograft™ Fine Mix of Cancellous Chips and Demineralized Bone Powder and a Canine Metacarpal Segment.
- 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 Osteo-Allograft Fine Mix was combined with the patients blood before packing into the surgical site (right).
- Figure 4.Seven months after surgery, the patient was enjoying normal activity.
- 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 patients own bone.
