Abstract:

BACKGROUND: We investigate the feasibility of calcium sulfate bone graft instead of allograft bone as a repair material for bone defects.
OBJECTIVE: To observe the clinical effects of calcium sulfate bone graft on bone defects. ·
METHODS: Totally 67 patients with bone defects receiving calcium sulfate bone graft (n=31) and allograft bone (n=36) were enrolled. At 4, 8, 12 weeks after implantation, the bone resorption and biodegradation of bone graft were calculated based on X-ray films.
RESULTS AND CONCLUSION: The follow-up time was from 3 to 36 months with an average of 18 months. During the follow-up, there was no statistical difference in the degradation rate between the two groups. No benign bone tumor recurred in the bone graft area. X-ray films showed that new callus formed in the bone defect area at 3 months after implantation. These findings indicate that the calcium sulfate bone graft has a similar clinical effect to allograft bone.
