目的探讨腕关节三角纤维软骨复合体(TFCC)创伤性Palmer分型与尺骨变异之间的相关性。方法纳入自2015-01—2016-07诊治的66例TFCC损伤,按Palmer分型,以MRI诊断为标准,分析尺骨变异与Palmer分型的相关性。结果 MRI显示尺骨变异阴性12例,其中ⅠB型9例(75.0%),ⅠC型2例(16.7%),ⅠD型1例(8.3%)。尺骨变异中性30例,其中ⅠA型11例(36.7%),ⅠB型14例(46.7%),ⅠC型2例(6.6%),ⅠD型3例(10.0%)。尺骨变异阳性24例,其中ⅠB型8例(33.3%),ⅠC型1例(4.2%),ⅠD型15例(62.5%)。尺骨变异阴性中以PalmerⅠB型为主;尺骨变异中性以PalmerⅠB型为主,PalmerⅠA型次之。尺骨变异阳性中以PalmerⅠD型为主,PalmerⅠB型次之。结论创伤性TFCC各型损伤与尺骨变异间具有一定的规律,结合MRI检查可以有效提高诊断质量及效率。
Objective To investigate the association between traumatic Palmer classification of wrist triangular fibular cartilage complex (TFCC) and ulnar variability. Methods Sixty-six patients with TFCC who were diagnosed and treated from January 2015 to June 2016 were enrolled in the study. Palmer classification and MRI diagnosis were used as criteria to analyze the correlation between ulnar variation and Palmer classification. Results MRI showed 12 cases of negative ulnar abnormalities, including 9 cases of type ⅠB (75.0%), 2 cases of type ⅠC (16.7%) and 1 case of type ⅠD (8.3%). There were 30 cases of ulnar variability, including 11 cases of type IA (36.7%), 14 cases of type IB (46.7%), 2 cases of type 1C (6.6%) and 3 cases of type ID (10.0%). There were 24 cases of ulnar variation, including 8 cases of type IB (33.3%), 1 case of type C (4.2%) and 15 cases of type I D (62.5%). Palmer type B predominance in ulnar variability; Palmer type B predominance in ulnar variability, followed by Palmer type I A. PalmerⅠD type was the predominant part of ulnar variation, followed by PalmerⅠB type. Conclusion There is a certain regularity between the various types of traumatic TFCC and the ulnar variations. The combination of MRI and MRI can effectively improve the diagnostic quality and efficiency.
