Summary

Low back pain is one of the commonest complaints nowadays affecting nearly 20% of the population, Sacroiliac joint has been accused of being the primary cause of pain in about 10%: 27% of this population.

The sure diagnosis of sacroiliac joint pain is challenging because of multiple crossed factors of facet joint pain and intervertebral disc pain. Diagnosis can be done by history taking, local examination, imaging techniques, and controlled local anesthetic blocks.

Controlled local anesthetic blocks are diagnostic and therapeutic done by various methods either landmark-guided or imaging-assisted either by fluoroscopy, computed tomography (CT), magnetic resonance (MRI), or ultrasound-guided.

Lower cost, real-time viewing of needle leading to higher accuracy rate, and low ionizing radiation dose are favoring ultrasound-guided injection over other modalities.

Numerous treatment modalities are being used for sacroiliac joint pain ranging from physiotherapy and systemic analgesics like Non-steroidal anti-inflammatory drugs (NSAIDs) to minimally invasive intra-articular, periarticular injection, radiofrequency neurotomy, and surgical fusion of the joint.

Multiple injectates are being used for intraarticular injection most commonly local anesthetics and steroids which offer short-term symptomatic relief and delay the degenerative process.

The need for a longer duration effect directly affects the disease process itself aiming for accelerating the joint healing rate by biological growth factors found in human blood especially in platelets.

Platelet-rich plasma (PRP) has been used aiming to inject a high concentration of growth factors directly into the joint.

Platelet-rich fibrin (PRF), the second generation of platelet-rich plasma is now tried having the advantage of a simpler preparation and higher values of growth factors.

Description

Patient preparation:

History taking, physical examination, provocation tests (Gaenslen's test, Patrick's test, and Compression & distraction test), and investigations will be done according to the local protocol designed to evaluate these patients. This includes complete blood count, random blood glucose, serum creatinine & electrolytes, liver function tests, coagulation profile, and electrocardiogram (ECG).

Before the intervention, the participants will be informed about the visual analog scale (VAS) pain score (0-100 mm) (where 0=no pain and 100 = worst comprehensible pain) and the details of the procedures.

The patient will receive Midazolam 2 mg intravenous (IV) as a premedication. Intravenous access will be obtained with a 20-gauge intravenous (IV) cannula and monitors (pulse oximeter, electrocardiography, non-invasive blood pressure) will be applied.

We will use a high-frequency ultrasound probe .and a 22-gauge, 50 mm echogenic needle for performing the injection.

Injectable platelet-rich fibrin (iPRF) preparation:

blood collection will be done from the patient on the day of intervention in a 9 ml blank tube. Within maximum 2:3minutes from sampling, it will be placed in the horizontal centrifuge for a low-speed centrifuge for 8 minutes at 600 rpm 44 g. Upon termination of this process, the Orange color area in the tube (i-PRF) and the remaining blood materials below will be noticed. Then, the tubes will be opened cautiously to avoid remixing, 2.5 ml of i-PRF will be collected from the tubes using a 5ml syringe.

Ultrasound-guided technique:

The patient will be positioned in a prone position over a cushion and after -sterilization with povidone-iodine and draping, the probe will be positioned transversely over the 5th lumber spinous process then moving the probe downwards until sacrum can be identified. Then moving the probe slightly lateral till identifying the 1st posterior sacral foramina (seen as a break in the hyperechoic contour of the sacral wing) then moving the probe downwards till the 2nd posterior sacral foramina will be identified. Tilting the lateral part of the probe slightly upwards and visualizing lateral sacral crest, sacroiliac joint, and iliac bone. Using color Doppler to ensure the absence of vascularization at the injection site of the joint (if present moving the probe cranially or caudally until disappearance). after anesthetizing the skin with 2 ml of 2% lidocaine, the needle will be advanced in-plane to the joint and 0.1 ml of sterile water will be injected to ensure spread into sacroiliac joint by unidirectional flow with Color Doppler box then the 3.5 ml of 1% lidocaine and PRF mixture will be injected in the group (P) or 40 mg of methylprednisolone acetate (Depo-Medrol, Pfizer) (1 ml) and 1% lidocaine (2.5 ml) in the group (S).

Post-procedural care:

The Patient will be transferred to post-intervention care unit for 2 hours after the procedure monitoring heart rate, oxygen saturation, and any possible adverse effect then patients will be discharged to home with a prescription of Diclofenac potassium 50 mg tab three times daily (TID), diclofenac diethylamine gel topically TID and baclofen 10 mg tab TID.
