[Utility of platelet-rich plasma and growth factors bone in the bone defects. Regional Hospital Lic. Adolfo López Mateos, ISSSTE].

INTRODUCTION

The platelet-rich plasma is a concentrated of platelets with the presence of growth factors and proteins that serve as osteoconducer matrix for bone formation. We present the results obtained with the use of platelet-rich plasma and a hydroxyapatite and bovine collagen graft in the management of bone defects.

MATERIAL AND

METHODS

We studied eight patients with bone defects, treated surgically in whom platelet rich plasma and a hydroxyapatite and bovine collagen graft was used, with clinical and radiographic follow-up at 2, 4, 6, 10 and 18 weeks after surgery.

RESULTS

Starting on week 7 since surgery, evidence of osteointegration and bone callus formation, during the weeks 10 and 14 most cases showed bone consolidation. A case without consolidation through week 18.

DISCUSSION: The immediate response of the body tissue damaged is the accumulation of a large number of activated platelets, which release their granules and growth factors that promote the regeneration of tissues. It is possible to obtain platelet-rich plasma and accelerating the process of bone regeneration. Our study shows beneficial results with the use of platelet-rich plasma.
