Delaminating rotator cuff tears

By |2020-02-07T00:29:09+01:00February 7th, 2020|New cases, New literature|

It has already been pointed out, that the tendon quality is a very important factor regarding the outcome of rotator cuff reconstruction.[Chung SW et al.] Above all, in addition to the signs of tendinopathy, a delamination of the torn tendon should be highlighted. It is an additional negativ prognostic factor and complicates cuff repair. In delaminated tears the articular layer is usually retracted more than the bursal layer.[Bierry G et al.] Yet, imaging accuracy for determining the quality of a torn tendon is not known. Delaminating tear of the supraspinatus tendon. [...]

Hill-Sachs defect and Glenoid bone loss

By |2020-02-03T21:18:25+01:00February 3rd, 2020|New literature|

The concept of the "glenoid track" attempts to define critical and non-critical Hill-Sachs defects in relation to the extent of the glenoid bone loss [Di Giacomo G et al., Funakoshi T et al]. Although the concept and the corresponding measurements are the subject of ongoing discussion [Moroder et al.], it is currently recommended that the following information is provided in the report: the distance from the medial border of the Hill-Sachs-defect to the ISP footprint the depth of the Hill-Sachs-lesion and the amount of glenoid bone loss. This glenoid bone loss is [...]

SLAP: Nacey NC et al., Skeletal Radiol 2019

By |2020-01-20T14:17:07+01:00January 19th, 2020|New literature|

The sensitivity and specificity of MR arthrography for SLAP lesions is about 80% and 90% (Symanski et al., Arirachakaran et al.). Nacey et al. pointed out that in 1/3 of the patients who underwent arthroscopic SLAP repair, the lesions in MR arthrography did not show signal intensity of fluid / gadolinium in T2 / T1. The authors also found that the diagnosis of a SLAP lesion in the absence of fluid / Gd signal is still possible if secondary findings support a SLAP lesion (lateral orientation of signal, extension posterior to the [...]

Acromion morphology, recent literature

By |2020-01-20T14:19:36+01:00January 19th, 2020|New literature|

For the association between acromion morphology and rotator cuff tears, two independent meta-analyses confirmed moderate evidence that a far lateral extension of the acromion is a risk factor for rotator cuff tears (Andrade R et al., Docter S et al.). The risk for a re-tear after primary rotator cuff repair also appears to increase with far lateral extension of the acromion (Docter S et al., Sheean AJ et al.). However, a reliable cut-off value cannot be given. This limits the clinical utility of the “critical shoulder angle” and the “acromion index”. For [...]
