چکیده
Po raz pierwszy dane mi było zapoznać się z pracą Dra Krzyżanowskiego dotyczącą obrazowania ultrasonograficznego obrąbka stawu ramiennego w czasie organizowanego przez mój ośrodek w Katowicach we wrześniu br. sympozjum kliniczno-radiologicznego poświęconego diagnostyce barku. Przekonujące dynamiczne obrazy obrąbka, jakie zobaczyłem w czasie jego prezentacji, skłoniły mnie do przejrzenia piśmiennictwa poświęconego badaniu I was very pleased when I received the invitation of the Editors of the “Journal of Ultrasonography” to comment on the articles of Dr Wojciech Krzyżanowski and Dr Marta Tarczyńska(1,2).

The use of ultrasound in the assessment of the glenoid labrum of the glenohumeral joint. Part II: Examples of labral pathologies
Labral pathologies of the glenohumeral joint are most commonly caused by trauma. The majority of lesions affect the anterior part of labrum, resulting from much higher frequency of anterior shoulder dislocations over posterior ones. Another subgroup of labral lesions, not directly related to joint instability, are SLAP tears. Other findings include degenerative changes of labrum and paralabral ...
متن کاملThe use of ultrasound in the assessment of the glenoid labrum of the glenohumeral joint. Part I: Ultrasound anatomy and examination technique
The glenohumeral joint is a spherical articulation with a remarkable range of motion in several planes and decreased stability. The maintenance of joint stability is influenced by the functioning of specific muscle groups in the shoulder region, a complex system of ligaments reinforcing the joint capsule, and the labrum which augments the glenoid fossa. Lesions of the aforementioned structures ...
متن کاملAssessment of anterior shoulder instability by CT arthrography.
Computed tomography (CT) immediately after double-contrast shoulder arthrography was taken in twenty-two young male patients with anterior shoulder instability including recurrent dislocation and subluxation. This recently developed technique called CT arthrography can provide significant information about patients with glenohumeral instability which is difficult to obtain by conventional arthr...
متن کاملSuperior Glenoid Labrum Displacement with Humeral Head Translation
INTRODUCTION: The stability of the glenohumeral joint (GHJ) is dependent upon passive stabilizing mechanisms such as the glenoid labrum and long head of the biceps (LHB) tendon. The labrum improves GHJ stability by increasing the glenoid concavity, and the contiguous structure of the labrum and LHB tendon may increase tension on the labrum during superior humeral translations which may contribu...
متن کاملEffects of biceps tension and superior humeral head translation on the glenoid labrum.
We sought to understand the effects of superior humeral head translation and load of the long head of biceps on the pathomechanics of the superior glenoid labrum by predicting labral strain. Using micro-CT cadaver images, a finite element model of the glenohumeral joint was generated, consisting of humerus, glenoid bone, cartilages, labrum, and biceps tendon. A glenohumeral compression of 50 N ...
