[iii] CONCLUSION
This study analyzed FCF bone morphology in 72 femurs by sex. FHD-V and FHA values were greater in men, but there were no discernible sex or side differences in other parameters. In contrast to earlier research, the majority of FCFs were found in the posterosuperior quadrant. Most foramina were concentrated in for fovea for ligament of head of femur forms, which included oval, circular, triangular, and piriform shapes; FCF had no foramina. Differences in shape, foramina location, and sex were negligible. There was a mild association between A-FCF and FN and a moderate link between A-FCF and FHA. These discoveries provide important new information for anthropological and medicinal applications.
[iv] Background:
The purpose of this study is to compare acetabular remodeling rates in age and severity matched, idiopathic DDH patients undergoing closed reduction (CR) versus open reduction alone (OR) versus open reduction supplemented by ligamentum teres reconstruction (LTR) utilizing a suture button device.
Conclusions:
Short-term results suggest that enhanced stability provided by LTR may permit more robust acetabular remodeling and lead to less residual dysplasia in patients with idiopathic DDH.
[v] Additionally, the abnormal contact between the articulating surfaces in the hip joint can cause the mechanical symptoms of catching, clicking, or locking.1 Other possible pathologies such as capsular laxity, ligamentum teres tears, chondral lesions, or synovial inflammation may alter joint mechanics and result in symptomatic giving way.7 Furthermore, patients with pathological hips may experience comparatively limited range of motion, contributing to feelings of stiffness.9,14

[vi] Aside from the vessels derived from the femoral artery, the artery of the ligamentum teres (occasionally referred to as the foveolar artery or acetabular artery), which originates from the internal iliac artery via the obturator artery, is also known to contribute to the blood supply of the femoral head in the embryonic and early life stages (Crock, 1965; Morris et al., 2022). The contribution of this artery to the blood supply of the femoral head decreases over time, with the literature suggesting that the dominant blood supply shifts to the femoral circumflex circuit by 18 months of age (Seeley et al., 2016). Recently, however, the artery of the ligamentum teres has also been shown to play a role in the revascularization of the femoral head in children afflicted with LCPD (Morris et al., 2022).
The most widely accepted porcine model of LCPD relies on surgically accessing the femoral head, performing a capsulotomy, transecting the ligamentum teres, and securing a non-absorbable suture around the femoral neck, thus ligating the retinacular arteries (H. K. Kim et al., 2001; H. K. W. Kim et al., 2005; Tomaru et al., 2024; Figure 2). This model has been shown to be reliable and reproducible in our (Armstrong et al., 2023; Buko, Armstrong, et al., 2024; Buko, Bhave, et al., 2024; Johnson et al., 2022) and others’ hands (Jaramillo et al., 1996; H. K. W. Kim, 2012) over the years.
[vii] The acetabulum had an acetabular lip along the entire edge, ending in the acetabular notch region with the transverse ligament of the acetabulum. The extensive joint capsule was inserted next to the external margin of the acetabular lip and in the transition region between the femoral head and neck, covering the contour of the femoral neck distally to where the cartilage covering the femoral head ends. After opening the capsule, an intra-articular ligament from the femoral head fovea to the acetabular fossa was visible, characterized as the femoral head ligament. The CF joint was medially related to the femoral artery, vein, and nerve. The sciatic nerve was located dorsocaudal to the acetabulum, so craniolateral access is recommended for arthrocentesis.
[viii] Purpose (the aim of the study): Pathologies of the acetabular fossa may be a currently underrecognized cause of hip pain and an early sign of hip osteoarthritis. This study aimed to investigate MRI abnormalities of the pulvinar and ligamentum teres (LT) in patients with atraumatic hip pain, as well as to describe a grading system for pulvinar effusion-synovitis on MRI and test its reproducibility.
[ix] However, the first reliable description of the ligament of the head of human femur is contained in § 1 of the treatise «On the Instruments of Reduction» [Mochlicon] by Hippocrates of Kos (born ca. 460 BCE) (1886AdamsF:162; 1941Гиппократ:89).
As documented in the «Mishneh Torah» (ca. 1176 – ca. 1178) (Forbidden Foods 8.1), we read: «[The prohibition against partaking of] the gid hanesheh applies with regard to kosher domesticated animals and wild beasts, even nevelot and trefot. It applies to a fetus and to animals that have been consecrated, both those consecrated [for sacrifices] of which we partake and for sacrifices of which we do not partake. It applies to [the gid] on the right thigh and that on the left thigh. According to Scriptural Law, only [the gid] on the hip socket is forbidden, as [Genesis 32:33] states: "which is on the hip-socket." The remainder of the gid which is above the socket or below the socket - and similarly, the fat which is on the gid – are forbidden only according to Rabbinic decree. There are two giddim. The inner one next to the bone is forbidden according to Scriptural Law. The entire outer one is forbidden by Rabbinic decree.» (1986–2007BenMaimonM, sefaria.org). Significantly, this physician's interpretation supports the identification identification of the anatomical structure as a ligament located within the joint, specifically the ligamentum teres (ligamentum capitis femoris), rather than the more superficial sciatic nerve.
