Les injections PRP (platelet-rich plasma)
PRP are platelet concentrations; it is plasma withhighconcentration of platelets.
We find also growth factors in important concentration. Platelets are cells circulating in the blood, with a lifespan of 10 to 15 days, containing compounds essential to haemostasis. They are formed in the bone marrow and are transferred into the blood, where they play an active role in blood coagulation. These cells also contain growth factors, compounds that are active in tissue healing after an injury. Here are some of them: PDGF (platelet-derived growth factor), TGF (transforming growth factor), VEG (vascular growth factor) or FGF (fibroblast growth factor)…
A blood collectionis performedfrom the patient. The collected blood is centrifuged. Separation of bloodcompounds occurs, with an upper layer of plasma, a lower layer of red blood cells, and an intermediate layer between them, which contains platelets with growth factors. This intermediate layer is sampled (a special set is required). Growth factors have a beneficial effect on various diseases, particularly tendinitis, bursitis, chondropathy and early arthrosis.
The volume to be injected depends on the indication, usually between 3 and 6 cc. In conclusion, PRP is plasma with high concentration of plateletsand growth factors, with great potential in post-traumatic wound healing.
Why are these injections administered for tendinitis?
Inflammation in the tendon involves rupture-type small lesions, specifically stretches of the collagen fibres of the tendon, of which scarring leadstoinflammation with release, among other, of factors that cause pain. By injecting these concentrated growth factors, healing of tendinitis is often achieved, using a natural product without side effects.
How does this happen?
Blood sampling of approximately 20-60 cc is required. Bloodis placed in a centrifuge tube and then, the concentrated layer containing growth factors is collected. This process takes 15 minutes. Then we can inject between 2 and 6 cc to an injury. Sometimes a single injection is sufficient; if not, this procedure can be repeated 2 to 3 times.
