Zur Differenzialdiagnostik des „signalkompromittierten” Os lunatum in der MR-Tomographie

Abstract

The lunate may be affected by different pathological states of the wrist. In total, only one quarter of the signal-compromised lunate represented Kienboeck's disease.

Diagnostic Accuracy of Magnetic Resonance Imaging and Magnetic Resonance Arthrography for Triangular Fibrocartilaginous Complex Injury

“…In total, 3581 citations were initially identified, and seventy-four of them were deemed potentially relevant. On full review of the twentyseven studies that initially satisfied the eligibility criteria, four were excluded because they did not provide sufficient data for meta-analysis after attempts were made to contact the respective corresponding authors 24,34-36 , one paper did not present the results of the TFCC assessment 37 , and one paper 38 was a dual publication to a second paper 39 . In this final case, only the earlier publication was included in the final review.…”

The incidence and distribution of stress fractures in elite tennis players

“…Radiographs were non-specific and MRI showed lunate bone marrow oedema in short T1 inversion recovery (STIR) and T1 weighted sequences without a fracture line (fig 4). Schmitt et al 41 have reported Kienbock's disease as the most common cause of abnormal signal intensity in the lunate on MRI, followed by ulnolunate impaction syndromes and intraosseous ganglion. Lunate stress fracture should be differentiated from osteonecrosis and should be considered in the differential diagnosis in athletes complaining of dorsal wrist pain.…”

Hydroxyapatite deposition disease of the wrist with intraosseous migration to the lunate bone

“…as cellulitis, infectious arthritis or gout [ 17 ]. In addition, there are some important differential diagnoses in particular the bone marrow oedema of the lunate, which can usually be resolved radiologically based on the distribution pattern of the oedema, lunate and carpal morphology, ulnar variance, as well as clinical symptoms [ 19 , 20 ]: (a) Kienböck’s disease is often associated with ulnar minus variance, proximal necrosis zone and radial localized bone marrow oedema. (b) Ulnar impaction syndrome shows signal alterations at the ulnar side of the lunate, usually positive ulnar variance, and triangular fibrocartilage complex (TFCC) perforation.…”
