成人胫骨结节损伤的MRI表现

MRI Findings of Tibial Tubercle Injury in Adult

目的探讨成人胫骨结节损伤的MRI表现特征。方法回顾性分析14例成人胫骨结节损伤的临床和MRI资料。结果急性期损伤10例,均伴髌韧带远侧肥厚肿胀、信号增高;其中胫骨结节挫伤及不全撕脱7例,表现为胫骨结节水肿信号、与骨干分离不明显;胫骨结节完全撕脱3例,伴髌韧带回缩及骨折片明显游离;慢性期损伤4例,均伴胫骨结节骨性突起明显及髌韧带远侧高信号,1例骨碎片存留在髌韧带内。结论 MRI可清晰显示成人胫骨结节急慢性损伤的影像学特征,值得应用。

Objective To investigate the MRI features of tibial tubercle injury in adult. Methods A retrospective analysis of clinical and MRI data of 14 cases with tibial tubercle injury in adult. Results Of all the cases, 10 cases were acute phase injury, were associated with Swelling, hypertrophy and increased signal in the distal of the patellar ligament.7 cases of the 10 cases were contusion and incomplete avulsion of the tibial tubercle, which showed edema signal and the separation of the backbone was not obvious.3 cases were completely avulsion of tibial tubercle, with patellar tendon retraction and free fracture. 4 cases were chronic injury, associated with obvious bony protrusion in tibial tubercle and high signal in the distal area of the patellar ligament, one case of bone fragments retained in the patellar tendon. Conclusion MRI imaging can clearly show the characteristic of the acute and chronic injury oftibial tubercle in adult,so which is worthy of application.
