The document discusses physeal (growth plate) injuries in children. It notes that physeal injuries represent 15-20% of injuries in children and can cause growth arrest and deformities. The most common sites are the distal radius, distal tibia, and phalanges. It describes the anatomy and blood supply of the physis. It discusses the Salter-Harris classification system for physeal fractures and treatment approaches including casting, splinting, and surgery. Complications of physeal injuries like growth arrest, angular deformity, and limb length discrepancy are also summarized. Long term follow up is needed to monitor bone healing and growth.
