- Abstract: STUDY DESIGN: A case controlled study with prospective data collection. PURPOSE: To evaluate the early influence and the final consequence of demineralized bone matrix (DBM) on auto-local bone as a graft enhancer in posterior lumbar interbody fusion (PLIF). OVERVIEW OF LITERATURE: DBM is known as an osteoinductive material; however, it has not been clearly recognized to enhance auto-local bone with a small amount. METHODS: Patients who had a PLIF were allocated into two groups. Group I (70 cases) used auto-local bone chips and group II (44 cases) used DBM as an additive to auto-local bone, 1 mL per a segment. Group selection was alternated. Early assessment was performed by computed tomography at 6 months and final assessment was done by simple radiography after 24 months at least. The degree of bone formation was assessed by 4 grade scale. RESULTS: The subjects of both groups were homogenous and had similar Oswestry Disability Index at final assessment. The ratio of auto-local bone chips and DBM was 6:1. The degree of bone formation at 6 months after surgery was superior in group II. However, there was no significant difference between the two groups at the final assessment. CONCLUSIONS: DBM was not recognized to enhance auto-local bone with small amount.
