“…MRI, while less sensitive has been shown to also have some utility in reaching a preoperative diagnosis of injury (20, 23). MRI arthrography with traction has been shown to have greater levels of sensitivity and specificity for both low grade and high-grade tears compared with MRI alone (24). Notably, in all of these studies arthroscopy has been used as the gold standard to determine the presence or absence of LT pathology.…”

The importance of the ligamentum teres (LT) in the hip is increasingly being recognized. However, the incidence of LT tears in the literature is extremely variable. Although classification systems exist their reliability in classifying LT pathology arthroscopically has not been well defined. To determine the inter- and intra-observer reliability of two existing classifications systems for the diagnosis of LT pathology at hip arthroscopy. Second, to identify key pathological findings currently not included. Four experienced hip-arthroscopists reviewed 40 standardized arthroscopic videos. Arthroscopic findings of the LT were classified using the Gray and Villar (G&V) and descriptive classification (DC). Reviewers were asked to record other relevant pathology encountered. Inter- and intra-observer reliability was defined using Fleiss-Kappa and Cohen-Kappa statistics. Both classifications demonstrated fair inter-observer reliability. The intra-observer reliability for G&V was moderate-to-substantial and for DC was slight-to-moderate. An absolute agreement rate of 10% (G&V) and 37.5% (DC) was found. Differentiation between normal, and partial or low-grade tears was a common source of disagreement. The prevalence of LT pathology was 90%. Synovitis was the most common diagnostic finding that was not included in either classification system used in this study. Arthroscopic classification of LT pathology using the G&V and the DC demonstrated only fair inter-observer reliability. The major discrepancy in interpretation was between normal, and partial or low-grade tears. The presence of synovitis was not in either classification but was considered an important arthroscopic finding. Thorough arthroscopic scrutiny reveals the prevalence of LT pathology is higher than previously reported.

“…Initial results of traction MR arthrography of the hip showed high accuracy in detecting chondrolabral lesions, lesions of the ligamentum teres, and intra-articular loose bodies. [132][133][134][135] In our experience, traction is not only helpful in detecting cartilage delamination but also in visualizing the whole extent of cartilage damage in older patients with mild radiographic joint degeneration. In these patients the referring surgeons request advanced imaging with traction to determine whether a joint-preserving surgery is still a reasonable treatment option based on the already present cartilage degeneration (►Fig.…”

Over the last 2 decades, the definition of pathomechanical concepts that link osseous deformities to chondrolabral damage and expose young and active patients to the risk of early osteoarthritis has led to a tremendous increase in the number of joint-preserving surgeries performed. The rise in arthroscopic procedures has led to an increasing demand for comprehensive preoperative magnetic resonance imaging (MRI) assessment of the hip joint. This includes conventional MRI for the assessment of extra-articular and periarticular pathologies such as greater trochanteric pain, deep gluteal pain syndrome, and sports injuries. Magnetic resonance arthrography with or without traction is reserved for the accurate evaluation of deformities associated with impingement and hip instability and for detecting the resulting intra-articular lesions. This article summarizes the current standard imaging techniques that the radiologist should know. It also explores the potential of computer-assisted analysis of three-dimensional MRI for virtual impingement simulation and volumetric analysis of cartilage composition and geometry.

Usefulness of MR arthrography of the hip with leg traction in the evaluation of ligamentum teres injuries

Abstract: MR arthrography with leg traction offers accurate diagnosis of ligamentum teres injuries. Patients with complete tears of the ligamentum teres exhibit increased articular distraction that may indicate secondary hip instability.
