Posterior Shoulder Instability
2020
Posterior shoulder instability is often hard to diagnose with clinical examination. Patients generally present with vague pain, weakness, and/or joint clicking but less frequently complaining of frank sensation of instability. Imaging examinations, especially MR imaging and magnetic resonance arthrography, have a pivotal role in the identification and management of this condition. This review describes the pathologic micro/macrotraumatic magnetic resonance features of posterior shoulder instability as well as the underlying joint abnormalities predisposing to this condition, including developmental anomalies of the glenoid fossa, humeral head, posterior labrum, and capsular and ligamentous …
MR-Tomographie versus CT-Arthrographie bei glenohumeralen Instabilitäten
1992
In a prospective study the diagnostic value of MRI compared to CT arthrography (CT-A) was evaluated in 26 patients with 27 instable shoulder joints. Surgical and/or arthroscopic correlation was available in all cases. Both methods showed a high accuracy (96% CT-A, 94% MRI) in the evaluation of the glenoid labrum. CT-A was significantly superior to MRI in the detection of capsular lesions (sensitivity 96% vs. 44%, accuracy 96% vs. 72%, negative predictive value 96% vs. 67%). CT-A and MRI results regarding humeral head fractures were similar; fractures of the glenoid rim were better detected by CT-A, the difference, however, was statistically not significant. Overall, CT-A proved to be superi…
Stellenwert der MR-Tomographie bei akuten Schulterluxationen
1992
24 patients up to two weeks after primary traumatic shoulder dislocation were examined at 0.5 and 1.5 T. Surgical and/or arthroscopic correlation was available in 13, CT-arthrographic correlation in 16 patients. A joint effusion allowing sufficient evaluation of the capsulolabral complex was present in 21/24 (87.5%) cases. 11/14 patients with combined dislocated detachments of the glenoid labrum and capsular lesions were subsequently operated upon. Marrow edema of the humeral head was found in 16/19 Hill-Sachs lesions and in 4/5 fractures of the greater tuberosity. Two patients presented with a lesion of the long biceps tendon associated with rotator cuff tears and were also subsequently op…
Magnētiskās rezonanses protokola pielietošana labrum plīsuma gadījumā
2019
Bakalaura darba tēma „Magnētiskās rezonanses protokola pielietošana labrum plīsuma gadījumā”. Tēmas aktualitāti nosaka tas, ka mūsdienās arvien biežāk tiek diagnosticēti labrum plīsumi ne tikai sportistiem, bet arī citiem cilvēkiem. MR ir uzlabojusi ārsta radiologa spēju diagnosticēt gūžas locītavas sāpju cēloņus un apkārtējo mīksto audu patoloģiju. Darba mērķis ir noskaidrot magnētiskās rezonanses protokola pielietošanu labrum plīsuma gadījumā. Pētniecības uzdevumi ir analizēt literatūru par gūžas locītavas normālu un magnētiskās rezonanses anatomiju, analizēt literatūru par labrum plīsuma veidiem gūžas locītavā un tā diagnostiku, analizēt literatūru par magnētiskās rezonanses pielietoto p…
