Sever’s disease refers to injury of a young athlete’s heel at the growth plate (at a young age the end of the bone has not fully fused this is called the growth plate). Usually aged between 8-15 years (James, Williams and Haines, 2013).
An apophysis is a normal growth plate in human bones, which, during reaching adulthood, fuses into “proper bone”. On Xray it can appear as a fracture in children because the apophysis is not closed yet.
Injury can be caused when excessive force of the calf muscle pulls along the Achilles which in turn pull on the growth plate in the heel. This commonly occurs in a young athlete during a growth spurt.
Management should involve following the PRICE principles and gaining flexibility in the lower limb muscles. According to literature (James, Williams and Haines, 2013), orthotics such as heel raises have not been found to be massively supportive treatment wise.
