Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to compare the efficacy of autologous enriched bone marrow cell implantation combined with core decompression to single core decompression for the treatment of avascular necrosis of femoral head.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

control group:core decompression

single core decompression

Group Type SHAM_COMPARATOR

core decompression

Intervention Type PROCEDURE

minimal surgical invention to drill a core to the femoral head to release pressure

Treatment group: BMCs+core decompression

Enriched bone marrow cells combined with core decompression

Group Type ACTIVE_COMPARATOR

Enriched BMCs implantation combined with core decompression

Intervention Type PROCEDURE

Patients are subjected to bone marrow aspiration from the anterior iliac crest. Mononuclear cells are enriched from patients' bone marrow by centrifuge, which are grafted with autologous cortical bone and implanted to the necrotic zone of the femoral head.
