NCT02877472

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

EXPERIMENTAL

Patients with avascular necrosis of the femoral head after femoral neck fracture surgery will undergo core decompression and porous tantalum rod implantation (experimental group).

Device: porous tantalum rod

Control group

EXPERIMENTAL

Patients with avascular necrosis of the femoral head after femoral neck fracture surgery will undergo core decompression (control group).

Procedure: core decompression
