脊柱生理曲度内在联系X线对照测量

根据力学和生理曲度的关系,分析脊柱生理曲率间可能存在的内在联系。选择有颈、胸、腰、骶部一处或多处疼痛,时间超过１月以上的病人１００例,另选１００例正常人做对照组。经Ｘ线侧位片测量,设计了脊柱生理弯曲平衡指数Ｋ值,测量全部观察组、对照组Ｋ值及观察组中Ｋ值与症状、体征的关系。随着年龄升高,Ｋ值逐步降低,至６０岁以后有少许反弹,依据Ｋ值将脊柱生理曲度内在关系分为三型,即生理型、变化型及退化型。变化型主要

X-RAY CONTROL-MEASUREMENT OF THE INTERNAL RELATIONS BETWEEN THE SPINAL PHYSA-OLOGICAL CURVES

The possible internal relations between the spinal physiological curves are analyzed from the relationship of biomechanics and physiological curvesin the paper. One hundred patients with Pains lasting more than one month in one or more of the neck, chest. waist and sacrum were taken as theobserved group, and 100 volunteers with the normal spine were taken as the control group. aamed on the measurements of the lateral X-ray views,the authors designed the balance index of the spinal physiological curves (BISPC), namely index ~ (cervical curve lumbar curve) / (thoraciccurve sacral curve). BISPC of both observed and control groups and the relation between BISPC of the observed group and the symptoms andsigns were measured. The results suggested that BISPC gradually reduced with age increase. and little rebounded after 60--year age. According toBISPC, the authors divided the internal relations between the spinal physiological curves into three types: the physiological. the changing and thedegenerative. The changing type was manifested mainly by local pain symptoms. while the degenerative type was manifested mostly by nerve-rootsymptoms. The change of BISPC is the early sign and the objective index of the spinal unstability and may be taken as the parameter for evaluatingthe internal relation between the spinal physiological curves.
