Effects of demineralized bone matrix on tendon-bone healing: an in vivo, experimental study on rabbits.

Objective: The aim of this study was to investigate the effects of demineralized bone matrix (DBM) on tendon-bone healing.

Methods: The extensor digitorum longus tendon was fixed with pegged suture technique in a tunnel at the proximal tibia in both legs of 12 New Zealand rabbits. Rabbit DBM was applied in the tunnel on the right limbs before fixation (study group), while the fixation was performed without DBM in the left legs (control group).
