Risk factors for ligamentum teres tears.

Purpose: The purpose of this study was to examine the relationship between nontraumatic ligamentum teres (LT) tears and acetabular radiographic architecture.

Methods: The inclusion criteria for this study were all patients who had anteroposterior pelvis radiographic views and had undergone arthroscopic examination of the LT. The exclusion criteria were Tonnis arthritic grade 3 and traumatic high-energy mechanisms of injury.

Femoral anteversion in the hip: comparison of measurement by computed tomography, magnetic resonance imaging, and physical examination.

Purpose: The purpose of this study was to evaluate the correlation between computed tomography (CT) and magnetic resonance imaging (MRI) measurements of femoral anteversion, as well as the relation of anteversion with physical examination and radiographic findings.

Methods: Preoperative CT and MRI measurements of anteversion along with clinical examination were performed on 129 consecutive hips before hip arthroscopy for nonarthritic hip injuries. All anteversion measurements were performed by 2 musculoskeletal radiologists.

Tears of the ligamentum teres: prevalence in hip arthroscopy using 2 classification systems.

Background: The ligamentum teres (LT) anatomy has been known for many years. While its functionality remains debatable, it is well recognized that the LT can be a source of pain in the hip joint. In 1997, a landmark publication by Gray and Villar established a classification for LT tears and increased the awareness of LT disorders.
