Minimally invasive core decompression with/without valgus intertrochanteric osteotomy for early-to-early-collapse avascular necrosis of the femoral head: A prospective case series

Rotational osteotomy and core decompression are viable surgical options for early-stage AVN of the femoral head. Both demonstrated favorable long-term outcomes in pain reduction and functional improvement. Larger studies are needed to confirm these findings and refine treatment guidelines.
