Piezo-focused shockwave therapy (PFST) is emerging as a promising non-invasive treatment for early-stage avascular necrosis (AVN) of the hip. Hereβs a detailed look at its role:
---
π§ Mechanism of Action in AVN HIP
PFST uses high-energy acoustic waves to stimulate biological responses in bone and surrounding tissues:
β’ Angiogenesis: Promotes formation of new blood vessels, helping restore circulation to ischemic bone tissue.
β’ Osteogenesis: Activates osteoblasts, encouraging bone regeneration and repair.
β’ Pain Modulation: Reduces inflammation and stimulates nerve endings to alleviate pain.
β’ Cellular Repair: Enhances cellular metabolism and tissue healing by increasing permeability and microcirculation.

π Clinical Benefits in Early AVN
Especially in the initial reversible stages of AVN, PFST offers several advantages:
Benefit Description
π©Ί Non-Invasive No incisions, anesthesia, or hospitalization required.
π Slows Progression May halt or reverse early necrosis by restoring blood flow and bone vitality.
π Reduced Medication Less reliance on painkillers or anti-inflammatory drugs.
π Minimal Downtime Patients often resume daily activities quickly.
πͺ Improved Function Enhances hip mobility and reduces stiffness.
Studies have shown that PFST can significantly improve pain scores and functional outcomes in patients with early-stage AVN A B C.

π§ͺ Evidence Snapshot
β’ A systematic review of 15 studies found that 9 supported ESWT (including PFST) as effective for osteonecrosis of the femoral head C.
β’ PFST has been integrated into multimodal protocols alongside TECAR, laser, and super inductive systems for synergistic effects D.

β οΈ Considerations
β’ Stage-Specific: Most effective in early AVN before structural collapse.
β’ Session Planning: Typically delivered in multiple sessions (20β30 minutes each).
β’ Patient Selection: Ideal for those contraindicated for surgery or seeking conservative.
