【摘要】 目的通过对腕舟月不稳的X线征象分析及参数测量来探讨征象及参数测量的价值,并分析其临床意义。方法回顾性分析21例舟月不稳的病例,并对其X线腕关节正侧位进行分析测量,观察征象包括:舟骨皮质环征、TerryThomas征;测量参数包括:舟月间距(SLG)、舟月角(SLA)及桡月角(RLA),对部分病例对照其MRI的韧带改变。结果舟月不稳的X线征象Terry-Thomas征4例,出现率为19%;舟骨皮质环征14例(阳性率66.7%)。X线测量舟月间距(3.7±1.6)mm(阳性率42.9%),舟月角63.5±18.20(阳性率61.9%),桡月角11.5±4.70(阳性率为57.1%)。X线上出现一种或多种舟月不稳阳性表现的病例为18例,占85.7%。结论 X线是诊断舟月不稳的基本方法,结合X线征象及参数测量能较好提示舟月不稳的诊断,舟月间距及SLA评估舟月不稳价值最大。更多还原

【Abstract】 Objective To explore the value and clinical significance of X-ray signs and parameters measurement by analyzing the X-ray signs and measuring several parameters of wrist scapholunate disstability cases.Methods We restropectively analyzed 21 cases of scapholunate disstability,measured parameters in the wrist posterior-anterior and lateral projection,signs including scaphoid cortical ring sign,Terry-Thomas sign including:scapholunate gap(SLG),scapholunate angle(SLA)and radiolunate angle(RLA),some cases in contrast to MRI findings.Results Terry-Thomas sign presents in4 cases,the occurrence rate is 19%;scaphoid cortical ring sign prensents in 14cases(positive rate:66.7%).Scapholunate gap is(3.7±1.6)mm(positive rate:42.9%),scapholunate angle is 63.5±18.20(positive rate:61.9%),radiolunate angle is 11.5±4.70(positive rate:57.1%).18 cases have one or more positive X-ray findings of scapholunate disstability,the sum positive rate is 85.7%.Conclusion X-ray is the basic modality in diagnosing scapholunate disstability,combination of X-ray signs and parameters measurement can well indicate the diagnosis of scapholunate disstability,the measurements of scapholunate gap and SLA are more valuable in evaluating scapholunate disstability.更多还原
