Oct 16, 2024 · Superior labral anterior posterior (SLAP) tears are injuries of the glenoid labrum, and can often be confused with a sublabral sulcus on MRI.

SLAP is an acronym that stands for 'Superior Labral tear from Anterior to Posterior'. SLAP tears start at the 12 o'clock position where the biceps anchor is located, which tears the labrum off the glenoid.

Nov 23, 2012 · We propose an MRI approach for evaluating suspected SLAP lesions based on specific abnormalities of the biceps-labral complex, presence or absence of extension of the lesion, and presence or absence of abnormalities of a number of additional structures (ligaments, adjacent cartilage, and tendons) .

In this web clinic, we discuss and illustrate the anatomy of the superior labrum, some of its anatomic variations, and patterns of labral failure, emphasizing those MR imaging features that allow differentiation between what is considered normal and what is regarded as pathologic.

Nov 23, 2012 · MRI evaluation of SLAP lesions should include an assessment of the shape, morphology, and signal characteristics of the labrum, biceps tendon attachment, glenohumeral ligaments, rotator interval, and adjacent soft-tissue and bony structures.

A SLAP-tear shoulder MRI may be performed without or with an injection of contrast material (dye) into the shoulder joint to help highlight the structures. 3T MR imaging allows very high-resolution images and results in more accurate diagnoses of …

Jul 31, 2018 · Interpretation of MR images requires knowledge of the normal appearance of the labrum, its anatomical variants, and the characteristic patterns of SLAP lesions. In general, high signal extending anterior and posterior to the biceps anchor is the hallmark of SLAP lesions.

frequency of types I–IV SLAP lesions has varied in the literature (type I, 9.5–21%; type II, 41–55%; type III, 6–33%; type IV, 3– 15%). Type II SLAP lesions are by far the most frequent type identified on arthroscopy, and a similar predominance is expected on MRI [2, 13, 23]. The first revised classification of SLAP le-

The patient's post traumatic pain and instability of left shoulder could be explained by the MRI finding of superior labrum anterior posterior (SLAP) lesion. The lesion could be type 3 or 4 depending upon whether the tear has extended to the biceps tendon which can be confirmed with MR arthrogram or arthroscopy.
