Brief Summary:
The objective of this study is to evaluate the fusion rate after the use of platelet rich plasma with autolgus bone graft and comparing it with bone graft alone

Condition or disease Intervention/treatment Phase
Platelet-Rich Plasma Biological: autologous platelet rich plasma Procedure: posteriolateral lumbar fusion only Phase 4

Detailed Description:

The study will be submitted for approval by the Ethics Committee of Faculty of Medicine, Assiut University, and written informed consent will be obtained from all patients prior to enrollment. The study population will be selected from patients attending the Department of Orthopedics and Trauma surgery, Assiut University hospitals.

A total of 104 patients treated with single level degenerative or lytic lumbar Spondylolisthesis indicated for PLF will be included ,patients will be classified into 2 groups Group A:Of 52 patients PLF + autologus bone graft+ PRP Group B: Of 52 patients treated with PLF + autologus bone graft only without adding PRP

Methods of evaluation

  • History taking.
  • Full clinical and neurological examination
  • Radiological evaluation by x-ray (antero posterior, lateral, and, CT scans provide excellent views of bony detail) and MRI if needed Method of randomization By shuffling cards method the candidate patient will choose one card from104 cards 52 of them containing fusion with PRP and the other 52 contaning Fusion without PRP

Platelet-rich plasma (PRP is obtained using a two-stage centrifugation process:

Whole blood sample will be drawn from the participant and be collected in a sterile tube containing anticoagulant (sodium citrate 3.8% or Ethylenediaminetetra acetic acid). The tube will be centrifuged at 160xg relative centrifugal force (about 1000 round per minute) for 10 min in a centrifugal apparatus. The first spin will separate platelet poor plasma at the top from red blood cells at the bottom and platelet rich plasma above (mixed with the white blood cells in the buffy coat). The Platelet poor plasma, Platelet rich plasma and a few red blood cells will be aspirated into a new tube, mixed and in the second spin, the tube will be centrifuged at 400xg relative centrifugal form (about 1500 round per minute) for another 10 minutes. The upper section will consist of Platelet poor plasma and the Platelet rich plasma will be collected at the bottom of the tube in the form of pellet. Then, Platelet poor plasma and Platelet rich plasma will be aspirated and mixed (discarding the upper portion). Prior to treatment calcium chloride 3% will be added to activate platelets specimen

the addition of autologous platelet rich plasma to the bone graft
Biological: autologous platelet rich plasma
adding autologous platelet rich plasma to the bone graft harvested from the patient

Active Comparator: posteriolateral lumbar fusion+bone graft only

Primary Outcome Measures :
  1. Lenke classification of posterolateral fusion success [ Time Frame: 6 month to1 year post-operative ]
    the degree of bridging bone across the fused vertebral bodies by using xray and CT scan

Secondary Outcome Measures :
  1. modified Oswestry disability index , [ Time Frame: 6 month to 1 year post-operative ]
    the functional outcome on the patient

  2. visual analogue scale [ Time Frame: 6 month to 1 year post-operative ]
    the amount of pain sensed by the patient pre and post-operative
