Brief Summary
To confirm 1) whether, compared with core decompression alone, core decompression with porous tantalum rod implantation improves the hip joint function of patients with avascular necrosis of the femoral head after femoral neck fracture surgery, 2) whether porous tantalum rod shows favorable biocompatibility with the human body, and 3) whether this treatment method is feasible for treating avascular necrosis of the femoral head after femoral neck fracture surgery.

Outcome Measures
Primary Outcomes (1)
Harris hip scores
To evaluate the recovery of hip joint function. The Harris hip score ranges from 0-100 points with higher scores indicating better hip joint function. Hip joint function is scored as follows: ≥ 90 is excellent, 80-89 very good, 70-79 good, and \< 70 poor.
12 months after surgery
Secondary Outcomes (2)
Visual Analogue Scale (VAS)
prior to and 1, 6, and 12 months after surgery
Incidences of complications
6 and 12 months after surgery
Study Arms (2)
Experimental group
EXPERIMENTALPatients with avascular necrosis of the femoral head after femoral neck fracture surgery will undergo core decompression and porous tantalum rod implantation (experimental group).
Control group
EXPERIMENTALPatients with avascular necrosis of the femoral head after femoral neck fracture surgery will undergo core decompression (control group).
Interventions
Patients with avascular necrosis of the femoral head after femoral head fracture surgery receive treatment of core decompression and porous tantalum rod implantation
Patients with avascular necrosis of the femoral head after femoral head fracture surgery will undergo core decompression.
