MAGNETIC RESONANCE IMAGING ARTHROGRAM FINDINGS IN RECURRENT DISLOCATION OF SHOULDER
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 44
Abstract
BACKGROUND Shoulder joint is the most commonly dislocated joint and it is most commonly dislocated anteriorly. Based on aetiology and age, there are associated injuries like injury to anterior-inferior labroligamentous restraints (in young people with traumatic aetiology) and to bony restraints (in elderly people). Injury to labroligamentous structures are best visualised using MRI and MR arthrography. Instability can be anterior, posterior and inferior or multidirectional. Anterior instability are associated with Bankart’s lesion and variants of it and injuries to anterior part of Inferior Glenohumeral Ligament (IGHL). With posterior instability lesions expected are reverse Bankart’s and reverse Hill-Sachs lesions. MATERIALS AND METHODS Twenty five patients who presented with recurrent dislocation of shoulder to casualty and op of orthopaedics of Govt. Medical College, Kozhikode from January 2015 to August 2016 were taken for study. Conventional MRI were taken and arthrography was done with USG guidance and MR arthrogram sections were taken. RESULTS Majority of patients with recurrent dislocation of shoulder were in age group between 15 - 30 years. Majority were males and right side was the most common side involved. Labroligamentous lesions were found in 100% of patients with both bony and labroligamentous lesions were more common than isolated labroligamentous lesions. About 44% of patients were having Bankart’s lesion and 40% of patients had Hill-Sachs lesion. Glenoid avulsion of glenoid labrum (GAGL- 40%) and SLAP (36%) were also common. CONCLUSION Imaging findings in recurrent dislocation of shoulder are variable, which mainly depends on aetiology and age of patients. In recurrent dislocation of shoulder MR arthrography is the investigation of choice, which is needed for early intervention. However, large scale study with large sample size are needed for definite conclusion.
