Many scholars agree that the marrow core decompression combined with porous tantalum bar implant treatment is one of the most main method of mid early femoral head necrosis, femoral head necrosis area is smaller, tantalum rod treatment effect on the femoral medullary core decompression can change within the femoral head closed state, reduce the intramedullary pressure, dredge venous stasis, increase blood flow, improve blood circulation.

The hardened and necrotic bones are removed by drilling holes in the femoral head, which is conducive to vascular regeneration and new bone growth, and initiates the process of wound repair and bone healing, thereby promoting the crawling replacement of the necrotic area.

The implantation of porous tantalum rods can provide effective structural support to prevent complications such as secondary femoral neck fracture and femoral head collapse caused by decompression of the core; in addition, porous tantalum rods have enhanced revascularization of necrotic areas. , Excellent biocompatibility, rapid bone growth and stress-free shielding.

Studies have shown that decompression of the core and implantation of porous tantalum rods can significantly improve hip joint function, improve hip joint survival, and delay or prevent femoral head collapse.
