【摘要】 目的分析腰椎峡部裂的CT征象及其临床意义。方法对45例腰椎峡部裂的CT表现与临床症状的关系进行了回顾性分析。结果45例腰椎峡部裂中,发生在L3见于2例,L4见于15例,以及L5见于28例。其中,单侧裂3例(6.7%),双侧裂42例(93.3%)。所有病例的CT表现包括“裂隙征”(n=45),“椎管冗长征”(n=24),假性椎间盘膨出(n=37),“双边征”(n=12),“双关节征”(n=7),椎管狭窄(n=14),侧隐窝狭窄(n=9),以及椎间孔狭窄(n=6)。结论CT扫描不仅是检查腰椎峡部裂的首选方法,而且可为解释临床症状和选择治疗方案提供重要依据。更多还原

【Abstract】 Objective To analyze the CT signs of lumbar spondylosc hi sis (LSS) and their clinical significance.Methods The correlation between CT fin dings and clinical cymptoms of 45 patients with LSS was analyzed retrospectively .Results Among 45 patients with LSS,there were 2 cases in L 3,15 in L 4,and 28 i n L 5.Of them,unilateral LSS were found in 3(6.7 % ) cases ,bilateral LSS in 42 (93.3 % ) cases.The spectrum of CT findings in all cases included “ fissure si gn” (n=45),vcrtebral canal prolongation sign"(n=24),pseudointervertebral disc h erniation (n=37),“ double-edge sign” (n=12),“ double-joint sign” (n=7),v ertebral canal narrowing (n=14),lateral crypt narrowing (n=9),and intervertebral foraman narrowing (n=6).Conclusicn CT scanning is not only a fist selective mea ns to detect LSS but it can provide important evidence to explain the clinical c ymptoms and to choose the therapeutic protocol.更多还原
