Muscle atrophy after surgery urgery of a radial tunnel syndrome.

T1 axial before and 5 months after surgery of a radial tunnel syndrome (= supinator syndrome). The postoperative examination was performed because of increasing weakness in the forearm. It shows a marked atrophy (purple arrows) and denervation edema (orange arrows) of the superficial part of the supinator muscle. Red arrows: Normal supinator muscle, superficial part. Green arrow: Normal supinator muscle, deep part. Blue arrow: Arcade of Frohse with deep branch of radial nerve.

Delaminating rotator cuff tears

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

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

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 [...]
