Abstract
The purpose of this study was to evaluate the effects of an autologous platelet rich-plasma on femoral fracture healing in experimentally induced rabbits’ model. In this study, 34 local breed rabbits, around 2-2.5 kg body weight, were divided into two equal groups randomly; Group A: platelet-rich plasma (PRP) and Groups B: Control group. Rabbits in both groups underwent a complete mid-shaft transverse osteotomy of the femur by a fine electrical saw. After fracture induction, the rabbits in group A (PRP group) were treated by application of 0.5 ml of autologous PRP at the site of the fractured bone, while in group B (control), rabbits were injected with distilled water. Samples from the fractured femur were collected at 10th, 20th, 30th days post operation for radiological evaluation and at 10th, 14th, 20th, and 30th days for histopathological evaluation. In radiological study, it was found that the rate of callus formation in rabbits treated with PRP (Group A) were faster than the control group (Group B) at different periods. Similarly, in histological finding it found that the stages of healing were faster in Group A when compared with Group B. It was concluded that using autologous PRP has beneficial effect to enhance the process of bone healing in the rabbit’s model.
