PEMF Therapy in Avascular Necrosis of the Hip: Preserving the Bone Before Collapse

A non-invasive, evidence-based solution to delay or prevent femoral head collapse in stages I–III of AVN

Avascular necrosis (AVN) of the hip is a progressive condition caused by reduced blood supply to the femoral head, leading to bone tissue death. If left untreated, the disease often advances to the collapse of the femoral head, causing severe pain and functional disability that frequently ends in total hip replacement.

The early and intermediate stages of AVN — Ficat I, II and III — are critical. At these stages, the bone is weakened but not yet irreversibly damaged, making timely intervention essential to preserve joint integrity.

Among conservative treatment options, Pulsed Electromagnetic Fields (PEMFs) stand out as a non-invasive and scientifically validated therapy. By applying low-frequency electromagnetic waves, PEMFs stimulate bone cells (osteoblasts) to produce new tissue, enhance local microcirculation, and promote natural repair mechanisms.

Clinical evidence shows that patients treated with PEMFs at early stages of AVN may achieve:

Delay or prevention of femoral head collapse,

Pain reduction and functional improvement,

Better quality of life and prolonged joint preservation.

For patients in stages I–III, PEMF therapy represents an effective, safe, and patient-friendly solution that can postpone or even avoid surgical intervention, offering valuable time and preserving joint function.
