Closed reduction percutaneous pinning (CRPP) is a surgical procedure used to correct bone fractures. It is typically performed by a pediatric orthopedic surgeon and involves the use of pins and screws to hold the bones in place while they heal. This type of surgery is often used for fractures that occur in the growth plates of children, as it can help to prevent deformities from developing. In some cases, CRPP may also be used for fractures that occur in adults. This procedure can be performed on an outpatient basis, and typically takes less than an hour to complete. Recovery times vary depending on the location and severity of the fracture but are typically around six weeks. Closed reduction percutaneous pinning is a safe and effective way to treat bone fractures, and can help patients return to their normal activities as quickly as possible.
