Percutaneously drilling through femoral head and neck fenestration combining with compacted autograft for early femoral head necrosis: A retrospective study

摘要

Abstract Background The purpose of this study was to evaluate the clinical results, survivorship and quick rehabilitation effects of modified surgery of percutaneously drilling and decompression through femoral head and neck fenestration combined with compacted autograft for early femoral head necrosis. Methods We conducted a retrospective cohort study with 83 hips performed percutaneous decompression through femoral head and neck fenestration (Modified group) combined with autogenous bone grafting for early ONFH. For comparison, another 90 hips treated with conventional core decompression with bone grafting (Control group). Results Median follow-up was 36 months (32–44 months). The length of incision, blood loss in operation, incision drainage, operation time and hospital stays in Modified group had better results than those in control group (P? ?0.05). There were 22 hips progressed to stage III in Modified group, while 23 hips progressed to stage III in control group (P?=?0.89). The clinical success rate in Modified group were 86.7%, compared with that in control group (87.8%) (?P=?0.84). Conclusion Percutaneous drilling and decompression through femoral head and neck fenestration combined with compacted autograft we reported showed an good surgical effect with a quick rehabilitation and had similar short-term effects compared with the conventional core decompression in treatment of early ONFH.
