 conventional magnetic resonance imaging in evaluation of bunkers and hill sacs lesion and their coexistence in anterior shoulder dislocation. Abstract. Objective. The aim of this study is to assess the role of conventional MRI in the evaluation of bunkers and hill sacs lesion and their coexistence in anterior shoulder dislocation. Material and methods. A retrospective study was conducted over a period of three years on 30 patients aged between 20 and 60 years who were referred to our radiology department with suspicion of anterior shoulder dislocation. In our study there was male preponderance, right shoulder was most commonly involved than left shoulder, anger age group people are most commonly affected and more liable to undergo recurrent dislocation. Privilege of bunkers and hill sacs in primary dislocation is 65% and 78% respectively and in recurrent dislocation it is 68% and 62.5% respectively. There is strong association between these two lesions. This study helps to predict the presence of one lesion if the other is present. Introduction. Shoulder joint is a ball and socket type of synovial joint formed between head of humerus and glenoid force of scapula. It is the most mobile and most commonly dislocated joint in the body. This glenohumeral joint is supported superiorly anteriorly and posteriorly by rotator cuff muscles. Dislocation of humerus head androinferiorly causes damage to anterior inferior rim of glenoid resulting in instability and if not managed may lead to recurrent dislocation of joint. Due to recurrent dislocation significant bone loss and erosion occur, bone defect which develops as a result of impaction of glenoid rim on humeral head is hill sac solution. Bunkers is detachment of anterior inferior labrum from glenoid. Perth is detachment of anterior inferior labrum with medially stripped but intact periosteal. Alpsa it is anterior labral periosteal sleeve evolution. It is medially displaced labral ligamentus complex with absence of labrum on glenoid rim. Glenolabral articular disruption it presents as partial tear of anterior inferior labrum with adjacent cartilage damage. Reverse bunkers, similar lesion but at postrow inferior labrum. Reverse hill sacs, similar hatchet like defect on bone but postrow superiorly. Objective aim of the study is to assess the role of conventional MRA in evaluation of bunkers and hill sacs and their co-existence in anterior shoulder dislocation. Material and methods it is a retrospective study 30 patients fulfilling the selection criteria were considered. 1.5 Tesla Siemens MRA machine has been used for imaging purpose. Inclusion criteria, patients who were referred to radiology department with clinical suspicion of anterior shoulder dislocation were considered. Exclusion criteria, patients with ferromagnetic implants, pacemakers, cochlear implants and enduro-smell clips. Results total 30 patients were studied, majority were male and female were 20%, male to female ratio 4 is to 1. Age age group is 34 years and average age of 30 patients is 37 years. Age group range is 20 to 45 years. Right shoulder most commonly affected than left shoulder. This is a bunkers and hill sacs lesion, bony bunkers and hill sacs lesions, glad glenolabral articular disruption lesion, total 30 patients, primary dislocation in 8 patients, recurrent dislocation in 22 patients. In primary dislocation bunkers is seen in 6 patients, hill sacs in 5 patients. In recurrent dislocation bunkers is seen in 15 patients and hill sacs 11 patients. Alpsa is seen in number of cases seen is 5, glad 2, birth is 3, regular bunkers 11. Conclusion, conventional MRA plays an important role in evaluation of bunkers and hill sacs lesion and their variants because of soft tissue resolution, ability to identify ligament tears and tendon tears more appropriately. Religious and hill sacs lesions coexistence, if one lesion is present chance of other being present was more than 2 to enough times likely. These are the references. Thank you.
