This study describes the prevalence, distribution, pathology and pathogenesis of lumbar interspinous bursitis (described as a clinical syndrome by Baastrup in 1933). It is based on an anatomic study of 152 lumbar spines derived from routine and random postmortem material, together with selected specimens from autopsies on patients with various rheumatic diseases. From a statistical study of 50 randomly chosen spines, bursae are found when the interspinous distance is small compared with the total height of the lumbar spine ('bursal index'): nearly all bursal spaces show some sign of inflammation and a few show severe bony erosion. Crystal deposits therein are also described.
本研究描述了腰椎棘突间滑囊炎（1933年由巴斯楚普描述为一种临床综合征）的患病率、分布、病理及发病机制。该研究基于对152个腰椎椎体的解剖学研究，这些椎体来源于常规随机尸检材料，以及从患有各种风湿性疾病患者的尸检中选取的标本。通过对50个随机选取的椎体进行统计研究发现，当棘突间距离与腰椎总高度相比很小时（“滑囊指数”）会出现滑囊：几乎所有滑囊间隙都有一些炎症迹象，少数有严重的骨质侵蚀。还描述了其中的晶体沉积物。
