[i]  … Ligamentum teres as a means of tethering the femoral head within the acetabulum. …

… After a standard capsulotomy, the ligamentum teres was released deeply within the acetabulum but left attached to the femoral head, … ligamentum teres is tensioned.

An absorbable monofilament grip stitch was brought through the ligament’s free end, … the hip flexed, internally rotated, and abducted, the ligamentum teres was pulled through the acetabular suture loop drawing the femoral head deeply into the acetabulum. … 

 

[ii] Future trends in arthroscopic treatment of acute dislocation (ligamentum teres and capsule) … In these cases, more than in a normal hip, joint stability relies on the integrity of the labrum, the capsule and the ligamentum teres which are disrupted at …

 

[iii] … hip arthroscopy can be beneficial for managing labral, cartilage and ligamentum teres tears.

 

[iv]  The rotated caudal segment of the femoral head with the ligamentum attached could prevent a concentric reduction of the cranial head segment.

 

[v] The management of borderline hip dysplasia (BHD) ... Labral hypertrophy, an upsloping lateral sourcil, fovea alta, ligamentum teres tears, Tönnis angle, Femoro-Epiphyseal Acetabular Roof index, vertical center anterior angle, and abnormal femoral or acetabular version are additional factors that help us understand dynamic pathoanatomy and the severity of instability. Some of these variablesdincluding Tönnis angle >10-15, ligamentum teres pathology, and vertical center anterior angle <18 have been associated with failure of arthroscopy alone for BHD.

  

[vi]  As ligamentum teres, the capsule and its vessels are severed, blood flow to the femoral head is impeded while the dislocated hip can exert pressure on the sciatic nerve, necessitating immediate reduction, usually under general anesthesia …

 

[vii] Ligamentum teres runs from the inferior margin of the acetabulum and inserts into the fovea capitis of the femoral head (Fig. 2). It forms the only intra-articular connection between the pelvis and femur and functions as an intrinsic stabilizer of …

 

[viii] The traditional LCPD piglet model uses an open surgical approach to the hip joint combined with transection of the ligamentum teres and its artery, to allow hip subluxation and placement of an encircling ligature around the femoral neck to interrupt the vascular supply [5]. While this animal model has been instrumental in improving our understanding of the pathogenesis and treatment of LCPD [5–18], there are multiple aspects of this model that poorly represent LCPD as it is seen in children. First, hip arthrotomy and subluxation are invasive and may induce an altered healing response in the model, unlike the spontaneous onset of disease in children. Second, the importance of the artery of the ligamentum teres (foveal artery) in the pathogenesis and subsequent healing of LCPD has been recognized [19,20], thus its transection in the traditional LCPD model may interfere with accurately capturing the disease.

Angiography and CTA identified three arteries, in addition to the artery of the ligamentum teres, that were suspected to contribute to the vascular supply of the femoral head in piglets. Embolization of two of these three vessels resulted in ischemia of the proximal femur, confirming their role in supplying the femoral head.

  

[ix] … and 11 had torn or avulsed ligamentum teres.

 

[x] A diagnostic arthroscopy is always performed first to visualize the labrum, articular cartilage, fovea, ligamentum teres, and capsule.

 

[xi] Delayed diagnosis often leads to prolonged return to play and progression of low grade to more severe injuries. These injuries, caused by repetitive stress or acute trauma, include fractures, hip dislocations, and intra-articular abnormalities, such as femoroacetabular impingement, labral tears, cartilage defects, and ligamentum teres tears. 

It (ligamentum teres) is pyramidally shaped with two or three distinct fascicles, extending from its origin at the acetabular notch to the fovea capitis of the femoral head, containing both proprioceptive and nociceptive fibers. This ligament is relatively weak … 

Fig. … partial disruption of the proximal fibers of the ligamentum teres (arrow) …

 

[xii] Two studies [22, 23] comprising 10 patients (12 hips) investigated outcomes in patients undergoing arthroscopic ligamentum teres reconstruction (LTR) (Table 1).

 

[xiii] 31.1 Vascular anatomy of the femoral head blood supply is provided by the foveal artery, which lies within the ligamentum teres. The MFCA (medial femoral circumflex artery), terminating in the posterior and superior retinacular vessels, is the main blood supply to the femoral head in adults. 

Carefully continue to flex and externally rotate the hip to dislocate the femoral head. If the ligamentum teres is still attached, it may need to be transected with the use of long curved mayo scissors, episiotomy scissors, or scalpel. However, this is usually attached to the fracture fragment, and dislocation is easy in this situation.

  

[xiv] Arthroscopy following traumatic hip dislocation has been shown to identify labral tears, intraarticular bodies, ligamentum teres injuries, and chondral damage not recognized on CT [23].


[xv] Degenerative changes were also recorded in the spine and the heads of both femurs, particularly in the area of the ligament of the head of the femur connecting the femur to the acetabulum of the pelvic bone. Potentially linked to excessive strain on the ligament.

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.
