Osteonecrosis of the femoral head (ONFH) is a destructive condition most commonly affecting young and middle-aged patients. The leading consequence of ONFH is often a significant articular disability. Effective joint-preserving surgical treatments are urgently needed for patients with early stage ONFH when outcomes of treatment are in general better than the advanced stage disease.
To introduce a new surgery procedure called percutaneous expanded core decompression and mixed bone graft technique, which is a new way of joint-preserving surgical treatments.
The clinical data of 6 patients with ONFH diagnosed and treated with the procedure called percutaneous expanded core decompression and mixed bone graft technique at The First Hospital of Qiqihar from March 2013 to August 2019 were retrospectively analyzed; the follow-up ended in December 2019.
There were 6 male patients with an average age of 43 years in our study. Gratifying results have been obtained from the comparison of Harris hip score, visual analogue scale, and imaging examination before and after operation.
This new modified technique is simple, safe, and reliable. No serious perioperative complications were observed in our cases. Advantages of the single blade expandable reamer are obvious. The adjuvant substance is inexpensive and easy to obtain. Thus, this technique is an effective joint-preserving surgical treatment for patients with early stage of ONFH.
股骨头坏死（ONFH）是一种破坏性疾病，最常影响中青年患者。ONFH的主要后果通常是严重的关节功能障碍。对于早期ONFH患者，迫切需要有效的保关节手术治疗，因为早期治疗效果通常优于晚期疾病。
介绍一种名为经皮扩大髓芯减压及混合骨移植技术的新手术方法，这是一种保关节手术治疗的新方式。
回顾性分析2013年3月至2019年8月在齐齐哈尔市第一医院采用经皮扩大髓芯减压及混合骨移植技术诊断和治疗的6例ONFH患者的临床资料；随访于2019年12月结束。
本研究中有6例男性患者，平均年龄43岁。通过对术后Harris髋关节评分、视觉模拟评分和影像学检查结果的比较，取得了满意的效果。
这种新的改良技术简单、安全、可靠。我们的病例中未观察到严重的围手术期并发症。单刃可扩张铰刀的优势明显。辅助物质价格低廉且易于获得。因此，该技术是早期ONFH患者有效的保关节手术治疗方法。
