Anterior approach ultrasound guided arthrogram injections are a quick reliable way of injecting contrast prior to MRI scan. We did a retrospective study on patients, previously injected and scanned at our clinic, to compare the more manifested posterior approach with the anterior approach. The success rate for successful intra-articular injections for the anterior approach far outweighs the posterior approach. Also the anterior approach is more tolerable for patients as the injections are much quicker and seemingly less painful. In our knowledge it is thus far better to perform anterior approach shoulder arthrogram injections than posterior approach injections
