Abstract: Objective To apply 3 .0T MRI in diagnosing injuries of anterior bundle of medial collateral ligament after elbow dislo‐cation .Methods The MRI features of the injuries of medial collateral ligament anterior bundle were analyzed retrospectively in 20 patients with elbow dislocation .The coronal ,sagittal ,axial and lamina oblique coronal were scanned routinely with SE T1WI ,T2WI‐FS sequences .Results Varying degrees of anterior bundle injuries of medial collateral ligament were observed in all the 20 patients ,in‐cluding the mild injury(n=8) ,part avnlsion(n=5) ,completely rupture(n=7) .Furthermore ,concomitant injuries including lateral collateral ligament(n=11) ,ringlike ligament(n=5) ,flex/stretch muscle tendon(n=9) ,and the fracture(n=7) were also observed . Conclusion The injuries of medial collateral ligament anterior bundle after elbow dislocation could be diagnosed accurately with 3 .0T MRI and the degree of injuries could also be defined on image .The 3 .0T MRI could be recommended as regular examination to pa‐tients with elbow dislocation .
