The Conservative Treatment of Osteonecrosis of the Femoral Head

The role of electrical stimulation in the management of avascular necrosis of the femoral head in adults: a systematic review

“…The pathophysiology has not been clearly defined however various mechanisms have been implicated and specific risk factors have been associated with the development of AVN. These include smoking, corticosteroid administration, diabetes mellitus, systemic lupus erythematous, rheumatoid arthritis and sickle cell disease amongst others [ 3 – 6 ].…”

“…These strain related potentials transfer information to the osteocyte regarding it’s biophysical environment. The use of exogenous electrical currents of the correct amplitude and frequency have been shown to have positive effects on bone formation, bone graft incorporation and bone repair in in vivo and in vitro models [ 6 , 9 ]. Pulsed electromagnetic fields have been shown to decrease parathyroid hormone receptor activity on osteoblasts and to reduce the lysosomal content of osteoclasts thereby suppressing bone resorption and increasing bone mass [ 9 ].…”

“…Invasive techniques whereby an implantable current generating unit supplies a constant direct current (DC) have been described in the literature and often these involve implanting the cathode to the site of bone repair and the anode in the nearby soft tissues. This is usually done in conjunction with a core decompression and necessitates surgical removal following treatment is accomplished [ 6 , 10 , 11 ].…”

A Prospective Study on Role of Cemented Total Hip Arthroplasty in Osteonecrosis of Hip Joint with Femoral Head Collapse in Elderly: A Study of 100 Cases

“…In modern era, total hip replacement is treatment modality of choice in advanced cases of osteoarthrosis of hip joint. [3] Avascular necrosis (AVN) head of femur is an extremely debilitating disease due to multifactorial etiology occuring in relatively younger patients. It results in a collapse of necrotic segment leading to loss of congruence and subsequently degenerative arthritis of the hip joint.…”

Pulsierende Elektromagnetische Felder in der Behandlung von Verletzungen und Erkrankungen der Bewegungsorgane - eine Übersicht und Metaanalyse

“…Allderdings bezieht sich dieses Ergebnis nur auf den Knochen distal der Verlängerung. Im Bereich der Verlängerungsstrecke konnte keine Veränderung im Vergleich zur Kontrollgruppe beobachtet werden 2. Auch bei einem Follow-up von 8 Jahren konnte kein Unterschied festgestellt werden[98].…”
