“…8 Amongst 33 patients in our study, superior, middle and inferior glenohumeral ligaments were identified in 12.1%, 24.2% and 6.1% patients while these were detected in 90.9%, 84.8% and 93.9 % patients on MR arthrography. This is in close approximation to the previous study [10] in which the superior, middle and inferior glenohumeral ligaments were identified on MR arthrograms in 85%, 85% and 91 % of the patients respectively. Palmer et al, [11] identified superior GHL in 98% of 48 patients with MR arthrography which is in close consensus with our study.…”

BACKGROUND:The purpose of the study was to evaluate the role of MR arthrography in identification and characterization of normal variants, rotator cuff tears and tears of labroligamentous complex of the glenohumeral joint and compare it with conventional MRI. AIMS AND OBJECTIVES: Identification, signal characterization and grading of rotator cuff tears and to detect, localize and characterize tears of the labroligamentous complex and to differentiate them from the normal variants. METHODS: Thirty three patients in the age group of 18-60 years with history of shoulder instability or persistent pain due to previous injury were prospectively evaluated with conventional MRI followed by MR arthrography. Patients with active joint infection, contrast allergy and joint effusion were excluded from the study. Conventional MRI and MR arthrographic findings were recorded separately and then compared. RESULTS: Statistically significant difference was found between conventional MRI and MR arthrography in the identification and characterization of labroligamentous tears while no statistical difference was found between the two in detection of rotator cuff tears. High incidence of co-occurrence was found between hill-sachs defect and bankart lesions/variants. CONCLUSIONS: MR arthrography is superior to conventional MRI for the delineation of intra-articular structures of the glenohumeral joint and in the detection and characterization of labral tears. Since rotator cuff tears are commoner in older age group in comparison to labral tears which are commoner in patients aged less than 40 years, MR arthrography is the imaging modality of choice in younger age group, irrespective of the clinical indication.

Ann R Coll Surg Engl 2009; 91: 2-7 2The glenohumeral joint of the shoulder is the most commonly dislocated joint in the human body. Acute dislocation is a surgical emergency and demands urgent relocation. Failure to reduce a dislocated shoulder successfully within the first 24 hours carries the risk that it will be impossible to achieve a stable closed reduction. 1Broadly speaking, anterior shoulder dislocation shows a bimodal age distribution (Fig. 1) Anterior dislocation of the shoulder is commonly seen in accident and emergency (A&E) and trauma clinics. In this article, we review the existing literature on the injury and the recent trends in management. MATERIALS AND METHODS We have discussed this condition with our colleagues and performed a Medline search ('anterior shoulder dislocation') of the relevant papers. We also describe key historical publications and recent developments regarding immobilisation of the joint. RESULTS Management decisions regarding this condition continue to vary between units, especially for recurrent and posterior dislocation. This paper lays some emphasis on the choice of analgesic agent when attempting shoulder reduction in the A&E setting. A summary of the data from our own department has provided a graphical representation of the classical age and sex distribution for this condition. CONCLUSIONS Shoulder dislocation is a common injury. Delays in diagnosis remain the single biggest obstacle to optimum results in this group of patients. A significant proportion will require eventual surgery and up to a third of these patients will go on to develop long-term shoulder arthritis. Even patients who have experienced a single episode of dislocation may go on to develop long-term sequelae.

“…Therefore, joint capsule itself can be depicted as a low intensity band, when fluid is present in the joint (Horii et al 1997). Recently, the usefulness of MR arthrography, using Gd-DTPA solution for evaluation of the labral-ligamentous complex of the shoulder, has been reported (Palmer et al 1994, Chandnani et al 1995, but equivalent images can be obtained by using 10 mL physiological saline.…”
