关节盘形态学特征及盘髁角度对可复性关节盘前移位保守治疗效果的初步评价
Effect of disc morphological features and disc-condyle angles on conservative treatment for anterior disc displace-ment with reduction
摘要
Abstract
Objective This study aimed to evaluate the effect of disc morphology and disc-condyle angle on the treat-ment of anterior repositioning splint(ARS)for anterior disc displacement with reduction(ADDwR).Methods On the basis of the inclusion and exclusion criteria,a total of 11 patients diagnosed with ADDwR were included.The effects of changes in disc length,thickness,and morphology classifications on the clinical symptoms,disc morphology parameters,and disc-condyle angles after ARS treatment were evaluated using magnetic resonance imaging and the Helkimo index.Results After ARS treatment,the Ai and Di of all patients with ADDwR decreased,the disc length increased,and the thickness decreased.The Ai of patients with slight ADDwR and those with type 1 joint discs was reduced to 0,with the most significant decrease observed in Di.The disc length of mild ADDwR(increased to 8.65 mm±1.79 mm)and type 5 disc(increased to 10.71 mm±2.62 mm)significant-ly increased the most.The disc thickness of slight AD-DwR decreased to 3.08 mm±0.51 mm significantly.Con-clusion The therapeutic effect of ARS is correlated with the displacement degree and morphological features of the disc,providing evidence for clinical treatment decisions.关键词
