摘　　要：目的 探讨肱二头肌长头腱(LHBT)脱位分型及其常规磁共振成像(MRI)表现。方法 回顾性收集31例LHBT脱位患者MRI资料,分析不同脱位类型间LHBT、喙肱韧带外侧部(LCHL)、喙肱韧带内侧部-盂肱上韧带复合体(MCHL-SGHL)、肱横韧带(THL)、肩胛下肌腱(SSC)及冈上肌腱(SSP)撕裂率差异性及其MRI表现。结果 31例患者中,半脱位14例,全脱位17例(Ⅰ型10例,Ⅱ型6例,Ⅲ型1例),2组以上结构撕裂数依次分别为9例与11例;4例与13例;11例与16例;5例与16例;8例与17例;10例与11例。其中LCHL、THL及SSC撕裂率低于全脱位组(P均<0.05),且所有结构撕裂率在全脱位亚型间差异均无统计学意义(P均>0.05)。结论 LHBT脱位常合并自身及其固定结构的撕裂,诊断时应仔细全面观察。Objective To investigate the relationship between the dislocation of the long head tendon of the biceps(LHBT)and the damage to surrounding tissue structure.Methods The MRI data of 31 patients with arthroscopy-conformed biceps tendon dislocation were retrospectively enrolled.The difference in tear rates of LHBT,lateral coracohumeral ligament(LCHL),medial coracohumeral ligamental-superior glenohumeral ligament complex(MCHL-SGHL),transverse humeral ligament(THL),subscapularis tendon(SSC)and supraspinatus tendon(SSP)and their MRI manifestations were contrasted and analyzed.Results For 31 patients,14 cases showed subluxation,while17 cases showed dislocation(10 withⅠtype,6 withⅡtype,and 1 withⅢtype).The torn numbers of the structures mentioned above in the subluxation and dislocation group were 9 cases vs 11 cases,4 cases vs 13 cases,11 cases vs16 cases,5 cases vs 16 cases,8 cases vs 17 cases,and 10 cases vs 11 cases.The tear rates of LCHL,THL,and SSC in the subluxation group were lower than those in the dislocation group(all P<0.05),and there was no statistical difference in the tear rates of all structures among the subtypes of total dislocation(all P>0.05).Conclusion LHBT dislocation is often associated with the tears of itself and its fixed structures,which should be carefully and comprehensively observed in the diagnosis.
