Bucket Handle Tear Mri Sagittal

Bucket hand tears can manifest as sensitive but not specific signs 1.

Bucket handle tear mri sagittal. Unfortunately bucket handle tears of the meniscus are one of the more frequently missed tear patterns with mr imaging. The rule is effective because the normal meniscal body is 10 12mm in. In other words the tear widens or gaps. Chronic anterior cruciate ligament acl tear might be difficult to diagnose on mri.

The bow tie rule 1 2 is a useful mr interpretation sign that should increase a reader s sensitivity for the detection of bucket handle tears. Absent bow tie sign on sagittal view. The medial meniscus is more often involved than the lateral meniscus. This type of tear is typically associated with trauma and is often found in conjunction with acl tear or insufficiency when medial meniscus is involved but can occur in isolation.

A double pcl sign from a torn medial meniscus can essentially only be seen in patients who have an intact anterior cruciate ligament acl as this is required to prevent the flipped fragment from migrating further. Double acl sign bucket hand tears of the lateral meniscus on sagittal view. The double pcl sign appears on sagittal mri images of the knee when a bucket handle meniscal tear medial meniscus in 80 of cases flips towards the center of the joint so that it comes to lie anteroinferior to the posterior cruciate ligament pcl mimicking a second smaller pcl. Preoperative mri on sagittal view showed a tear in the anterior horn of the medial meniscus and a displaced fragment of the medial meniscus in front of the original anterior cruciate ligament acl which looks like another acl.

Double pcl sign bucket handle tears of the medial meniscus on sagittal view. The bow tie rule simply stated is that the normal meniscal body should be seen as at least two consecutive bow ties on consecutive sagittal images. Under arthroscopic examination the bucket handle medial meniscus displaced parallel to the acl was observed.
