Ultrasound-guided release of post-arthroscopy extra-articular hip adhesions in femoroacetabular impingement: a novel technique.

Objective: To explore a novel ultrasound-guided injection technique of releasing extra-articular anterior hip adhesions in arthroscopically treated femoroacetabular impingement patients.

Materials And Methods: IRB-approved pilot study included 24 consecutive patients referred for ultrasound-guided injection (Jan 1, 2017-Mar 31, 2018) with anterior hip pain and/or limited hip flexion following arthroscopic treatment for femoroacetabular impingement. They underwent ultrasound-guided pressure injection, releasing post-operative extra-articular adhesions between the joint capsule and flexor tendons along the arthroscopic portal followed by steroid instillation.

Early detection of metastases using whole-body MRI for initial staging and routine follow-up of myxoid liposarcoma.

Objective: To define the role of whole-body MRI (WBMRI) for initial staging and routine follow-up of myxoid liposarcoma (MLS).

Materials And Methods: A retrospective review of all the patients with MLS who underwent WBMRI for initial staging and routine follow-up at our institution between October 1, 2006, and September 30, 2016 was performed. Patient demographics, clinical presentation, imaging findings, tumor histology, and occurrence and location of metastatic disease were recorded.

Acute calcific tendinopathy of the popliteus tendon: a rare case diagnosed using a multimodality imaging approach and treated conservatively.

Acute calcific tendinopathy of the popliteus tendon is a rare medical entity associated with significant patient discomfort. We present the case of a previously healthy 48-year-old female who presented to the emergency department with acute onset of left knee pain. Initial radiographs revealed calcifications within the posterolateral compartment of the knee.
