[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 …

[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.
