A seven year old boy injured himself during a football match.
He had swelling over the proximal tibia.
The tibial apophysis can be avulsed by the patella tendon. The severity can cary from a small anterior avulsion, to complete separation of the apophysis with the whole growth plate. A patellar tendon rupture is also a possibility i these types of injury. Make sure that the injury is not an old one. Osgood Schlatter's disease is a chronic partial separation of the tibial spine (apophysis). Ask the patient about pre existing patellar pain and look for signs of chronicity on the x ray (rounded fracture edges, callus etc.). Osgood Schlatters's is usually treated conservatively.
This is a fresh injury. The avulsed tibial spine needs internal fixation. If you practice away from a suitable facility, splint the limb in a back-slab and refer to an Orthopaedic Surgeon.
