高频超声诊断胫骨结节骨软骨炎的临床应用

Diagnosis of Osgood-Schlatter Disease by High-frequency Ultrasonography

目的探讨高频超声对胫骨结节骨软骨炎（Osgood-Schlatter disease，OSD）的诊断价值。方法选择OSD患者30例和正常对照组25例，观察2组胫骨结节上下骨骺、髌腱末端下止点及周围软组织的声像图特征，并与X线检查结果对比。结果OSD组髌腱体部和末端厚度均较对照组明显增厚、增宽，且不同病变程度OSD的髌腱体部与末端宽度及厚度、骨骺受损面积、碎骨前凸距离及滑膜囊积液程度也存在显著差异。结论高频超声技术可对胫骨结节骨软骨炎做出较准确的评价，可作为该病的首选检查方法。

Objective To evaluate the diagnostic value of high-frequency ultrasonography for Osgood-Schlatter disease （OSD）. Methods 30 OSD cases and 25 normal control cases were included in the study. The ultrasonic characteristics of the upper and lower epiphyses of tibial apophysis, the distal insertion of patellar tendon and the soft tissue surrounded were executed by high frequency sonography. In addition, the results were compared with X-ray findings. Results In all OSD patients, the uhrasonographic abnormalities were observed as follows： widespread thickening of patellar tendon was commonly seen and more evident at its distal insert point, which was significant when compared with normal controls.The thickening degree of cartigage, area of synovial effusion and thickness of patellar at its distal insert point in OSD patients were more severe than in normal control cases. Conclusion High-frequency ultrasonography is a sensitive and accurate method to reveal fundamental pathological changes of Osgood- Schlatter diseases and could be the foremost examination method.
