Recently, a 4-year-old child was hit by a car, causing pain and bleeding in his left lower limb and limited movement. He was sent to the hospital for treatment. After emergency examination, he was admitted to the hospital for orthopedic treatment with diagnoses of "open injury to the lower limb, tendon contusion, and skin and soft tissue defects on the dorsum of the foot." Due to multiple abrasions and serious injuries, the maximum wound size was about 10cm*4cm, wound repair surgery was required. Considering that the child was young, ordinary skin grafting surgery required skin to be taken from other parts of the body, which would have a certain impact on the child's growth and development. The team of the Department of Orthopedics (Hand and Foot Microsurgery) of the Fifth Hospital of Nanchang combined the child's injury and comprehensively considered all factors to use "autologous platelet-rich plasma (PRP) technology" to repair the wound. After two PRP treatments, the child's wound has shrunk significantly in just 2 weeks, and has completely scabbed, and the surrounding skin has recovered well.

What is PRP?
"Autologous Platelet Rich Plasma Gel Technology" is a new regenerative medicine technology that has developed rapidly in recent years. PRP refers to extracting platelet concentrate from the patient's autologous blood through centrifugation. It contains high concentrations of platelets , white blood cells and fibrin and other complex growth factors to make a special "concentrated nutrient solution" that is attached to the wound to treat it.
What are the advantages of PRP in the treatment of chronic wounds?
With the continuous improvement of medical standards, the treatment methods for chronic wounds are becoming increasingly rich, mainly including: surgical treatment (debridement surgery, free skin grafting, skin flap transplantation), conventional dressing treatment, physical therapy (infrared therapy), closed negative pressure drainage therapy, growth factor drug therapy, etc. Although the above therapies can promote wound healing, they take a long time to heal and tend to leave scars , which can have adverse effects on the patient's skin function and appearance. PRP technology can mobilize the autologous repair ability, stimulate the growth of wound granulation , accelerate the natural repair and healing of the wound, and significantly improve the curative effect.
PRP is derived from the patient’s own blood and is very safe and will not produce any rejection reaction. In clinical applications, it has also been found that in addition to promoting rapid tissue repair and regeneration, PRP technology also has the effects of effectively reducing patient pain, significant anti-infection, anti-inflammatory and other effects when repairing difficult-to-heal wounds
