This degeneration occurs in the proximal epiphysis of the femur. It presents a progressive evolution; the most accredited etiopathogenetic hypothesis is of a double damage of both neurological and vascular type. Causes: many mechanisms are not yet known idiopathic 20% traumas (fractures - dislocations) chronic and continuous use of corticosteroids Ethylism coagulopathies metabolic diseases ionizing radiation dysbarism AIDS Therefore, it is commonly agreed that the first event is an alteration of blood flow with subsequent death of osteocytes and subchondral necrosis; this causes an interruption of the continuity of the necrotic bone that is subjected to shear forces, with subsequent deformation of the femoral head. Diagnosis: anamnesis clinical examination: pain usually sudden referred to groin and hip, even at rest and increased in upright position and during walking with lameness, can radiate to the anterior / antero-medial side of the thigh sometimes also to the gluteal region diagnostic tests: gold standard MRI Both the localization of the damage and the size of the same can vary; these characteristics are fundamental both for the treatment and the prognosis. Among the most used classifications in the diagnostic and therapeutic field there is the Steinberg classification, to which we refer for further information, from the initial stage I (conservative and physiotherapy treatment) to stage V (surgical treatment). Therapeutic course Most of the therapeutic effects of focal shock waves are determined by cavitation with microbubble formation. Didactically, we distinguish direct effects and indirect effects: direct: interface between tissues with different impedance (bone and soft tissue etc.) Indirect: Cavitation results in the production of (NO) which leads to vasodilation and neoangiogenesis. Vascularized tissues treated with OUFs undergo micro-trauma that activates anti-inflammatory, pain-relieving, and anti-edematous processes. Bottom line if you can get an early diagnosis.
