Evaluation of the effectiveness of platelet-rich plasma in the bone consolidation of patients submitted to lumbar arthrodesis.

Objective: To determine whether the use of autograft associated with platelet-rich plasma (PRP) increases bone healing in patients undergoing lumbar fusion.

Method: This was a prospective, descriptive, and comparative study, which included 40 patients undergoing lumbar fusion, who were divided into two groups: group I, autograft only, and group II, autograft associated with PRP. After surgery, patients were followed-up on the first, third, and sixth month.
