目的:评价0.5T磁共振(MRI)在肩关节撞击综合征诊断上的应用和价值,并分析总结其磁共振(MRI)征象及损伤机制。方法:我们对6例肩关节撞击综合征患者的临床资料进行回顾性研究,我们将这6例患者设定为观察组,将同一时间段内来我院进行体检的6例正常人作为对照组。结果:直接征象:6例患者均有冈上肌腱形态、信号变化,2例完全撕裂者,3例部分撕裂者,1例情况未明者;间接征象:肩峰下滑囊增厚患者有3例,肩峰下滑囊积液者3例;另外,有2例患者的关节盂唇并发撕裂状况;所有患者的肩峰形态为3例钩状、2例扁平状、1例弯曲状。两组患者AHD值比较差异具有统计学意义(P<0.05);两组患者MRI肩峰形态比较差异无统计学意义。结论:磁共振在肩关节撞击综合症病况的分析诊断中具有明显的效果,患者的病情反应清晰,此方法值得在临床上进一步推广应用。
OBJECTIVE: To evaluate the value of 0.5T magnetic resonance (MRI) in the diagnosis of shoulder impact syndrome and analyze its magnetic resonance imaging (MRI) signs and mechanisms. Methods: We retrospectively studied the clinical data of 6 patients with shoulder impact syndrome. We set these 6 patients as observation group and 6 normal people who came to our hospital for physical examination in the same time period as the control group . Results: The direct signs: the supraspinatus tendon morphology, signal changes, 2 cases of complete tear, 3 cases of partial tearing, 1 case unknown; Indirect signs: patients with subacromial bursa thickening 3 In 3 cases, there were 3 cases of acromiocervical effusions. In addition, there were 2 cases of joint labrum complicated with tearing. The shape of acromion was 3 cases of hook, 2 cases of flat and 1 case of curved. The difference of AHD between the two groups was statistically significant (P <0.05). There was no significant difference in the morphology of acromion in both groups. Conclusion: MRI has obvious effect in the analysis and diagnosis of the condition of shoulder impact syndrome, and the patient’s disease response is clear. This method deserves to be further popularized and applied in clinic.
