地方性大骨节病修复阶段数字化X线成像研究

目的：分析大骨节病修过渡阶段的数字化X线图像，制定该病的治疗方案提供客观依据。方法：对300例地方性大骨节病修复过渡阶段患者手骨正位、左肘关节正侧位、膝关节正侧位、左踝关节正侧位（还依据患者的体征和症状抽摄髋关节正位）DR成像分析。结果：300例地方性大骨节病修复过渡阶段，左手、左肘、左膝、左踝关节均有膨大，关节间隙变窄或不等宽窄，增生、硬化、关节面囊性变等。若忽视流行病学资料，本病易与骨关节退行性病变相互混淆。其中合并滑膜骨软骨瘤病10例，肘管综合症36例，肘外翻8例，膝内翻14例，酷似股骨头缺血性坏死13例。75例膝关节出现游离体115枚。结论：大骨节病修复过渡阶段以膝关节改变为多且严重，临床症状与DR成像改变有相关性、一致性，说明关节负荷愈重，临床症状与DR成像表现愈明显并对此类人群生存质量危害甚大。

Study on Repairing Period of Kashin-Bek Disease by Using DR Image

Objective:To analyze the DR images of patients with Kashin-Bek disease (KBD) in repairing period,and to provide evidence for its treatment.Methods:The radiographic images of left hand,left elbow and knee joint of 300 patients with Kashin-Bek disease (KBD) were analyzed.DR of hip joints were also taken in patients with clinical symptoms.Results:In 300 cases of KBD in repairing periods,there were enlargement of the joints of left hand,left elbow joint,left knee and left ankle,with narrowing of the joint space...
