The goals of treatment are to decrease pain, reduce perhhes loss of hip motion, and prevent or minimize permanent femoral head deformity so that the risk of developing a severe degenerative arthritis as adult can be reduced.

Non traumatic osteonecrosis of the femoral head: Over time, healing occurs by new blood vessels infiltrating the dead bone and removing the necrotic bone which leads to a loss of bone mass and a weakening of the femoral head. New cases of Perthes’ disease rarely occur after age 14 years if diagnosed after 14 years of age, then it is usually old disease from early in childhood or avascular necrosis from an enfermedzd cause.

Anticoagulant protein C pathway defective in majority of thromboembolic patients.

Variability of thrombosis among homozigous siblings with resistance to activated protein C due to an Arg-Gln mutaion in gen for factor V. Use of bisphosphonate such as zoledronate or ibandronate is currently being investigated, but definite recommendations are not yet available.

Slipped upper femoral epiphysis Slipped upper femoral epiphysis.

Conclusions Epidemiological and laboratory data from this group ofpediatric patients and from the control group do not supportthe hypothesis that a thrombogenesis defect couldbe the underlying cause of avascular necrosis of the hipjoint. Eventually, the femoral head begins to fragment stage 2with subchondral lucency crescent sign and redistribution of weight-bearing stresses leading to thickening of some trabeculae which become more prominent.

Accessed March 14, The efnermedad of metaphyseal involvement not only increases the likelihood of femoral neck deformity but also make early physeal closure with resulting leg length disparity more likely. Geographic and temporal trends in incidence reflecting differences in degree of deprivation in childhood”. The main long-term problem with this condition is that it can produce a permanent deformity of the femoral head, which increases the risk of developing osteoarthritis in adults.
