Epiphysis slippage, also known as epiphysiolysis, refers to the following situation: the epiphysis changes its normal location. Epiphysis slippage often occur at the femur top, and this often affects teenagers (aged from ten to sixteen).
In adolescents, the epiphysis sometimes may slip or shift, causing hip pain. If left untreated, this can lead to serious hip joint problems. Epiphysis slippage may have acute or chronic case. Other complications may also include: arthritis, chondrolysis, avascular necrosis.
The underlying cause is unknown, but this condition often occurs in obese children. This may be due to the following factor combination: rapid growth, minor traumas, and the epiphyseal plate obliquity.
