When advanced MRI is not about naming musculoskeletal lesions.

Nowadays, the use of advanced MRI sequences such as diffusion-weighted imaging or perfusion-weighted imaging in the field of musculoskeletal radiology remains limited compared to other anatomical regions and subspecialties. Several reasons underpin this, primarily technical challenges, and a longstanding reliance on conventional and morphological evaluations of soft tissue and bone lesions. Experienced radiologists often assert that these advanced sequences do not offer added diagnostic value, claiming that a morphological approach suffices.

Role of advanced MRI techniques for sacroiliitis assessment and quantification.

The introduction of MRI was supposed to be a qualitative leap for the evaluation of Sacroiliac Joint (SIJ) in patients with Axial Spondyloarthropathies (AS). In fact, MRI findings such as bone marrow edema around the SIJ has been incorporated into the Assessment in SpondyloArthritis International Society (ASAS criteria). However, in the era of functional imaging, a qualitative approach to SIJ by means of conventional MRI seems insufficient.

Susceptibility Weighted Imaging for evaluation of musculoskeletal lesions.

The presence of blood or calcium in the musculoskeletal (MSK) system may be linked to specific pathological conditions. The ability of MRI for calcium detection is usually limited compared with other techniques such as CT. In a similar manner, the accuracy of MRI for detection and evaluation of hemorrhage in soft tissues is closely linked to the degree of degradation of blood products.

Outside-in arthroscopic psoas release for anterior iliopsoas impingement after primary total hip arthroplasty.

Purpose: 1 of the causes of groin pain after total hip arthroplasty (THA) is impingement of the iliopsoas tendon. The purpose of this study was to present our results with outside-in arthroscopic tenotomy for iliopsoas impingement after THA.

Methods: We retrospectively reviewed 12 patients treated between 2009 and 2016 with a minimum follow-up of 2 years.

A 65-Year Follow-up of a Judet Prosthesis.

The Judet polymethylmethacrylate hip hemiarthroplasty can be considered a major step in the development of the current total hip replacement. It was designed by the Judet brothers and first implanted in 1946. Although initial results were encouraging, the procedure was abandoned years later because of breakages and wear of the acrylic material.

L5 radiculopathy secondary to migration of a revision stemmed acetabular cup.

Introduction: Stemmed acetabular components are used in patients undergoing revision total hip arthroplasty in cases with major acetabular defects or pelvic discontinuity. Conflicting results relating to the survival of the component, and complication rates are reported in the literature. We present a case of L5 radiculopathy secondary to proximal migration of this device.
