[i] The femoral head ligament was typical, extending from the femoral head fovea to the acetabular fossa [24,25]. (24. König, H.E.; Liebich, H.G.; Maierl, J.

[ii] In addition to the capsule and labrum, there are multiple other contributing factors to the suction seal including the surrounding joint fluid, ligamentum teres, and extra-capsular muscle tone.

 

[iii]   … ligamentum teres tear all aided in establishing a diagnosis of symptomatic hip instability.

 

[iv] The choice of treatment tactics was carried out taking into account the type of fracture according to the Pipkin classification and clinical data. Systematized according to the following types: – I — dislocation of the hip with a fracture of the head of the femur below the point of attachment of the round ligament (pit of the head); – II — dislocation of the hip with a fracture of the head of the femur above the point of attachment of the round ligament; – III — type I or II in combination with a femoral neck fracture; – IV — type I or II together with a fracture of the acetabulum.

  

[v] The ligament of the femoral head, also known as ligamentum teres, originates from the obturator crest and inserts into fibrous capsule of the hip joint.

  

[vi] Recent research suggests that the development of cam morphology is related to the repetitive shear stresses experienced at the hip joint during adolescence from skating. This condition likely increases the potential for intra-articular and extra-articular injuries in these athletes later in their careers. Research also indicates that the hip joint mechanics during forward skating substantially increase the possibility of sustaining a labral tear compared to other sports. Such an injury can increase femoral head movement within the joint, potentially causing secondary damage to the iliofemoral ligament, ligamentum teres and joint capsule. These injuries and the high density of nociceptors in the affected structures may explain the high prevalence of hip and groin pain in hockey athletes.

The most common hip pathologies observed in elite hockey athletes include: femoroacetabular impingement (FAI), injuries to the non-contractile tissues including the labrum, iliofemoral ligament (IFL), and ligamentum teres (LT), as well as muscular injuries, such as core muscle injuries (CMI), hip flexor, and adductor injuries.

  

[vii] Introduction. This study aims to evaluate the histology of the ligamentum teres and its relationship with matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS), which are involved in the destruction of extracellular matrix proteins in patients with developmental dysplasia of the hip (DDH).

Conclusions. The histological structure of ligamentum teres in patients with DDH shows moderate inflammation, fibrosis, neovascularization, hyalinization, and fatty infiltration regardless of age and radiological stage. ADAMTS-7, MMP-2, and MMP-9 correlate positively with the histological parameters of the ligamentum teres in patients with DDH.

  

[viii] The femoral head is approximately rounded and features a shallow pit known as the capital ligament fossa (as shown in Fig. 4I).

 

[ix] [There is an] … oblique ligament groove on the femoral head…

 

[x] The hip is further stabilized by static and dynamic stabilizers, including the fibrocartilaginous labrum, ligamentous hip capsule, ligamentum teres, and the musculature that courses across the hip joint.

[xii] At 6 weeks of age (mean weight = 10.6 ± 1.8 kg, range = 8.1–14.5 kg), piglets underwent surgery to induce complete (100%) ischemia of the epiphysis of the femoral head by placement of a ligature around the femoral neck and transection of the ligamentum teres.

…

Complete femoral head ischemia was confirmed in 10/11 piglets as determined by the complete absence of signal enhancement on subtracted CE-MRI. One piglet had partial femoral head ischemia and thus was excluded from the data analysis. In all cases, femoral head ischemia was limited to the epiphysis of the femoral head, whereas the metaphysis was perfused.

  

[xiii] The head of the femur is oriented medially and slightly ventrally in anterior view (Fig. 2A1). It has a rounded, semicircular outline, but poor preservation makes interpretation of other features difficult. For example, there appears to be a distinct ligament groove on the anterior surface extending parallel to the medial margin of the process, but this could be the result of erosion or damage as there is no cortical bone in this area.


[xiv] Abstract. In the past, the ligamentum teres of the hip joint was considered as a vestigial structure and its removal during surgical procedures was deemed acceptable. However, with the recent advancements in hip arthroscopy, there has been an increased interest in ligamentum teres injuries. This has led to various studies revealing notable characteristics of this ligament. The purpose of this review article is to describe the role of the ligamentum teres as a stabilizing factor in the hip joint, focusing on its anatomical and biomechanical characteristics. In addition, by identifying the causes of ligamentum teres injuries, we aim to present appropriate diagnostic methods and treatment approaches. Ultimately, we intend to provide comprehensive guidelines for the ligamentum teres injuries.

The role of the ligamentum teres in congenital dislocation of the hip (1970). The authors proposed an analogy for the role of the ligamentum capitis femoris (LCF) as a “ball and chain control” and noted that it can spontaneously reduce congenital hip dislocation. The text in Russian is available at the following link: 1970MichaelsG_MatlesAL . [ii]   Original text Quote p. 199 Many papers in the literature have implicated the ligamentum teres as a hindrance to the late open reduction of a congenitally dislocated hip. Occasionally the ligamentum teres has been reported to be absent. However, in most cases it is hypertrophied and elongated. Our present knowledge confirms the fact that congenital dislocation of t...

Catalog. Classifications of LCF Pathology

  The classifications are intended to systematize of ligamentum capitis femoris pathology and assist in the development of general approaches to its description, registration, analysis and treatment.   Keywords ligamentum capitis femoris, ligamentum teres, ligament of head of femur, hip joint, histology, pathological anatomy, pathology, trauma INTRODUCTION In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. The development of arthroscopic surgery has made it possible to identify various, previously undescribed types of LCF pathology, which prompted the development of various modern classifications based on intraoperative observations. Analysis of literature data and our own morphological observations allowed us to propose a General Classification of the Ligamentum Teres Pathology, which has the form of a collection of classifiers, as well as a Classification of Functions of the Ligamentum Teres.
