A severe contusion or tear that occurs to the quadriceps may lead to haematoma formation followed by acute inflammation. Treatment R.I.C.E. and strict rest. Occasionally drainage of the haematoma or excision after twelve months. This is a result of severe contraction when either accelerating or kicking. The pain is exacerbated by resistance of hip flexion in extension and full knee flexion in a prone position.
Players tend to be in their mid-teens.
Typical x-ray appearance. This is a result of excessive running, especially in adolescents. Repetitive strain is put upon the apophysis, compounded by tight hamstrings. There is violent external rotation, with the leg in a widely abducted position. Well localised tenderness.
