Shoulder joint pain due to anterior microinstability is not an unusual complaint of young active individuals. Different etiologies of such shoulder microinstability are encountered, mainly affecting the anterior–inferior labro-ligamentous capsular structures. These injuries include Perthes lesion, ALPSA, GLAD, RIT, SLAP and glenohumeral ligamentous injuries.
The aim of this study: The aim of this study is to enhance the role of MR arthrogram over routine MRI in the diagnosis of such subtle lesions.
Patients and methods: This is a prospective study, involving 30 consecutive patients of shoulder microinstability complaints, evaluated by MR arthrogram of the affected shoulder.
Results: Perthes lesions were diagnosed in 6 patients, ALPSA in 3 patients, GLAD in 2 patients, RIT in 2 patients and SLAP in 11 patients. Ligamentous injuries that include tear of MGHL, were found in 2 patients and IGHL in 4 patients.
Conclusion: MR arthrogram is highly recommended for the management of young patients with shoulder microinstability or unexplained painful movement complaints.
