Weekend Educational Course: Challenges in Imaging the Musculoskeletal System After Treatment

Skill Level: Basic

Organizers: Jenny T. Bencardino, M.D., Eric Y. Chang, M.D., Christine Chung, M.D., Ravinder R. Regatte, Ph.D., Philip Robinson, M.D. & Siegfried Trattnig, M.D.

Sunday 08 May 2016

Cover traditional and emerging medical therapies and surgical management of musculoskeletal disorders including repair mechanisms and postoperative complications.

Target Audience
Radiologists, Orthopedic surgeons, and clinical care providers who whish to update their knowledge on the use of MR in imaging musculoskeletal tissues after treatment.

Educational Objectives
Upon completion of this course, participants should be able to:

  • Describe the need for detailed of evaluation of patients with post-surgical changes in the joints;
  • Recognize the added value of MRI in evaluation of patients with post-operative complications; and
  • Describe the added value of MRI in the management of patients with metallic implants.

MR Imaging After Rotator Cuff Repair - Permission Withheld

Radiologists should understand and pay great degree of attention on the technical aspects of the operation, such as anchor types, suture patterns, suture materials, and instruments as well as expected and abnormal MR findings when read the post-operative MRI after rotator cuff repair surgery.

Imaging Following Shoulder Instability Surgery

Imaging following shoulder instability surgery depends on suspected pathology. Direct anatomic repair of labral tears may be perfomed in conjunction with capsular shift. There should be no separation of the labrocapsular complex and glenoid margin with intact labral repair. Overall accuracy of MR arthrography for detecting labral tears after prior instability repair is > 90%.  Arthroscopic Bankart repair may be performed in conjunction with remplissage procedure in patients with engaging Hill-Sachs lesion. MRI will show reattachment of posterior structures into the defect, along with anchor embedded in the trough. Postoperative imaging of Laterjet procedure must assess incorporation of the bone block and any recurrent imaging features of instability.

Postoperative Hip: FAI & Dysplasia
Young-Jo Kim
dGEMRIC is a biochemical imaging technique that can assess the charge density of cartilage.  Cartilage can respond to increased mechanical loading by increasing charge density.  In acetabular dysplasia, there is increased mechanical load due to the shallow acetabulum, which will normalize after pelvic osteotomy.  Prospective monitoring of the hip cartilage before and after osteotomy using dGEMRIC demonstrates that cartilage responds appropriately to alterations in hip mechanics after osteotomy for dysplastic hips.

Entrapment Neuropathies of the Pelvis Following Surgery
Gustav Andreisek
Entrapment neuropathies of the pelvis following surgery are rare but important causes for a negative outcome or complications after surgery.

Postoperative Ankle
James Linklater
Postoperative Knee: Menisci
Edwin Oei1
1Radiology & Nuclear Medicine, Erasmus MC Rotterdam, Rotterdam, Netherlands
In this lecture, the meniscal anatomy and the important role the meniscus plays in the structure and function of the knee will reviewed, followed by a discussion of the three surgical strategies for operative treatment of meniscal tears (resection, repair, and replacement). MR protocol choices for postoperative assessment of the meniscus will be presented as well as normal and abnormal MR imaging findings in the postoperative meniscus after each of the different surgical procedures.

Postoperative Knee: Ligaments
James Griffith
Postoperative Knee: Total Knee Replacement - Permission Withheld
Florian M Buck1
1University of Zurich, Zurich, Switzerland

The purpose of this presentation is to provide an overview of the possibilities and restrictions of todays MARS MR imaging techniques in patients after total knee replacement. After following this presentation, the learners will understand the major clinical problems faced by orthopedists after total knee replacement, how MR imaging can contribute in these situations and where the limitations of today’s technical possibilities are in a clinical setting.
