“…In our study the imaging features introduced by Tirman et al [21] and Tuite and Orwin [7] proved reliable to establish the diagnosis of a sublabral hole and a Buford complex, although the number of specimens with a Buford complex, of course, was too small to draw transferable conclusions.…”

Variants of the superior labrum and labro-bicipital complex: a comparative study of shoulder specimens using MR arthrography, multi-slice CT arthrography and anatomical dissection

The purpose of the present study was to evaluate the anatomical variability of the superior labrum and to compare the value of MR arthrography and multi-slice CT arthrography in the diagnosis of variants of the labro-bicipital complex. Forty-three human shoulder specimens (age range and mean age at death, 61-89 years and 78.3 years) were examined with the use of MR arthrography and multi-slice CT arthrography prior to joint exploration and macroscopic inspection of the superior labrum and labro-bicipital complex. Two radiologists evaluated MR and CT arthrograms, and the results were compared with macroscopic assessments. Anatomical dissection of all shoulder specimens revealed a sublabral recess in 32/43 (74%) cases. The attachment of the superior labrum was categorised as type 1 in ten (23%) cases, as type 2 in eight (19%), as type 3 in ten (23%), and as type 4 in 14 (33%) cases. One superior labrum showed detachment consistent with a superior labral anteroposterior (SLAP) type 3 lesion. On MR arthrography and CT arthrography the attachment of the superior labrum was categorised in concordance with macroscopic assessments in 79% and 84% of cases, respectively. The anteroposterior extension of sublabral recesses was accurately determined with MR and CT arthrography in 59% and 81% of cases, respectively. The attachment of the superior labrum shows considerable variability. Thus, exact depiction of variants is essential in order to avoid the false positive diagnosis of a superior labral tear (SLAP or Andrews lesion). Both, MR arthrography and multi-slice CT arthrography were effective in the detection and classification of sublabral recesses.

“…21 The sublabral foramen and the Buford complex are the most common variations, and several studies on their MRI appearance proved that they could be incorrectly interpreted as tears. 22,23 However, we did not have many normal variants that could be falsepositive interpretations in this study, and consequently the specificity of both MRA and MRI was relatively high. In our previous study on the diagnosis of unstable SLAP 2 lesions using MRI and CT arthrography, 18 there was only one case with a sulcus (a normal variant) at the attachment of the superior labrum out of 76 cases (a completely different patient group from the one in this study).…”

We compared efficacy of magnetic resonance arthrography (MRA) and magnetic resonance imaging (MRI) for the detection of superior glenoid labral detachment, and especially unstable superior labrum anterior-posterior (SLAP) type 2 lesions. MR imagings and MR arthrograms of 90 shoulders of 90 patients, including 30 shoulders of unstable SLAP 2 lesions, were interpreted by a novice and an expert observer. These results were correlated with arthroscopic findings. For the expert observer, MRI had a sensitivity of 53%, a specificity of 93%, and an accuracy of 80%, which were improved to 60%, 98%, and 85%, respectively, by MRA. These increases were statistically insignificant. For the novice observer, MRI had a sensitivity of 45%, a specificity of 80%, and an accuracy of 64%, which were significantly improved to 76%, 83%, and 80%, respectively, by MRA. In detecting unstable SLAP 2 lesions, MRA proved to be useful to a novice interpreter, but not significantly useful to an experienced interpreter, compared with unenhanced MRI. We advocate MRA as the examination of first choice for detecting unstable SLAP 2 lesions if they are strongly suspected clinically.

“…Auch hier finden sich in der Literatur Hinweise auf die Überlegen-heit der kontrastmittelgestützten gegenü-ber der nativen MRT-Untersuchung [4]. Auch die bei der Diagnostik zu würdi-genden möglichen"pitfalls" wurden bereits beschrieben [12]. Hinsichtlich der in unserer Studie auffällig hohen Versagerquote bei SLAP-Läsionen wird von Smith et al [10] zwar darauf verwiesen, dass eine prinzipielle Darstellbarkeit derartiger Verletzungen möglich ist, eine Stadieneinteilung jedoch schwierig sei.…”
