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

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. 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). 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
