目的 探討使用生物型非骨水泥假體治療髖臼內陷癥的近期療效。 方法 2007年6月－2010年5月，對11例12髖髖臼內陷患者行生物型假體全髖關節置換術。男2例，女9例；年齡38～57歲，平均47.3歲。其中繼發于類風濕性關節炎7例，創傷4例；病程1～18年，平均8.9年；輕度髖臼內陷6髖，中度髖臼內陷6髖。采用Harris評分標準進行臨床療效評估，攝X線片進行影像學評估。 結果 術后第2天X線片示，人工股骨頭距Kohler’s線外移（1.42 ± 2.27）mm，較術前股骨頭內陷（?5.17 ± 2.04）mm明顯改善（P＜0.05）。術后1周，患者Harris評分為（85.75 ± 4.73）分，較術前（39.75 ± 5.24）分顯著提高（P＜0.05）。術后1年X線片示髖臼假體與髖臼內側壁無透亮線，已骨融合。術后患者獲隨訪2～5年。髖臼假體均無松動移位、脫位或移植骨的吸收。 結論 使用生物型非骨水泥假體結合自體骨移植治療髖臼內陷癥，能有效恢復髖臼運動中心的解剖位置，近期臨床療效滿意。
Objective To explore the clinical efficacy and safety of percutaneous kyphoplasty (PKP) in the treatment of Kummell disease. Methods We retrospectively analyzed the clinical data of 11 patients with Kummell disease treated by PKP between January 2013 and January 2016. There were 8 males and 3 females with an average age of 72.3 years old ranging from 64 to 78. The injured vertebra was located at T11 in 2 patients, T12 in 3, and L1 in 6. All the patients suffered from lower back pain for 2.5-15.0 months averaging 7.6 months. Preoperative CT and MRI examinations showed that there were clear signs of intravertebral vacuum cleft and abnormal fluid signals. The Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and the height and kyphotic angle of the injured vertebral body were measured to evaluate the clinical outcomes before and after surgery. Results Follow-up was conducted for all 11 patients. Cement leakage occurred in 4 patients with no symptoms. The vertebral height, Cobb angel of the injured vertebra, VAS and ODI improved significantly after surgery and during the latest follow-up. Compared with those parameters after surgery, only VAS score was different during the latest follow-up. Conclusion PKP is safe and effective in the treatment of Kummell disease.
