The main problem causing pain in the Hip is osteoarthritis.
Primary osteoarthritis occurs in the middle aged and the elderly. The pain can be felt in the hip, groin, buttock or the lower back, and can be referred to the knee. Sleep is often disturbed and movement becomes restricted causing problems with every day activities.
The symptoms of secondary osteoarthritis are the same as for primary osteoarthritis but occurs in a younger age group due to a predisposing condition, such as congenital dislocation of the hip, hip dysplasia, Perthes disease, slipped femoral epiphysis, fracture or dislocation.
Referred pain into the hip, arising from a slipped disc, fracture and core muscle spasm, can also occur.
