[i] During traumatic hip fracture-dislocation, the attainment of concentric reduction in the joint is commonly impeded by the presence of a bony fragment and, less frequently, by injuries to the soft tissues such as a torn acetabular labrum, ruptured capsule, or ligamentum teres.  

Complications in patients who underwent open arthrotomy included a 37% incidence of postoperative heterotopic ossification (HO), along with cases of cosmetic deformity and ligamentum teres rupture.  


[ii] Patients aged ≥40 years had a higher prevalence of ligamentum teres damage (P< .001) and underwent ligamentum teres debridement at higher rates (54% vs 35%; P = .02) as well as higher rates of femoroplasty (74% vs 57%; P = .03).  


[iii] The fibroblasts in patients with AS (ankylosing spondylitis) were obtained from the ligamentum teres of the hip during total hip arthroplasty. 


[iv]  Persistent anterior or lateral hip impingement test might indicate an under resection of Cam or Pincer deformity and a possible re-tear of the labrum, a positive O'Donnell test might indicate ligamentum teres (LT) pathology,… 


[v] Studies show preliminary traction decreasing the incidence of AVN undergoing CR for DDH [20, 21, 22], but any traction will have an insignificant effect on the main obstacles for reduction for eg. pulvinar, tight hour-glass capsule, transverse acetabular ligament, hypertrophied ligamentum teres (all intracapsular).


[vi] Various factors may lead to poor results of hip arthroscopy in BDDH treatment [1, 25, 42]. Studies found that preoperative tearing of the round ligament can lead to lower mental and psychological scores in BDDH patients after hip arthroscopy, making it more difficult to achieve PASS, and significantly increasing the patient’s risk of reoperation or even THA [1, 20].

[vii] The femoral head, meanwhile, remains within the acetabulum, constrained by the ligamentum teres, but may rotate to assume a posteroinferior position relative to the shaft.

 

[viii] The primary reported cause is laxity of the soft tissues adjacent to the joint, including the round ligament of the femoral head and laxity of the joint capsule associated with hip dysplasia (Fossum, 2014).

Abstract

Background Hip-preserving surgery in young patients frequently reveals lesions of the ligamentum teres (LT). Histological and clinical evidence supports that those lesions could be source of intraarticular hip pain. It has been hypothesized that LT degeneration could be linked to the abnormal positioning of the fovea outside the lunate surface during various daily motions. We introduce the “fossa-foveolar mismatch” (FFM) by determining the trajectory of the fovea in the fossa during hip motions, enabling a comparison across diverse hip-pathomorphologies.

Conclusions The FFM-index showed excellent intraobserver reliability and interobserver reproducibility for all motions. This innovative approach deepens our understanding of biomechanical implications, providing valuable insights for identifying patient populations at risk. 


Fig. 1 The fossa-foveolar mismatch is illustrated by displaying (A) no fossa-foveolar mismatch and (B) presence of a fossa-foveolar mismatch with a pathologic foveolar tracking pattern for the motion of everyday life internal/external rotation in 90 degrees flexion (Commons Attribution 4.0 International)

Human LCF intersection

HUMAN LCF INTERSECTION In the south of China, in the Guangxi Zhuang Autonomous Region, the archaeological Neolithic site of Dingsishan was investigated. Burials of 355 people were found in this place. The authors of the article (2024YeZ_LiFJ) identified 91 skeletons with traces of manipulations with the remains. They are attributed to burials of the Dingsishan III-IV phase, aged 8.0-4.5 thousand years. 13 notches were found on the proximal part of various femurs. « Cutmarks on the femoral head, neck and intertrochanteric line, as well as along the medial linea aspera of the femoral shaft, suggest that soft tissue around the hip, including the iliofemoral ligament and the iliacus and adductor muscles, was severed to disarticulate the joint.» This and other postmortem bone injuries «... suggests that corpse treatment at Dingsishan included disarticulation » (2024YeZ_LiFJ).  Figure 4 of the cited article shows the distribution and direction of cutmarks on human skeletons from Dingx...

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

THE OLDEST LCF

  The very first four-legged animal, the lobe-finned fish Tiktaalik roseae, lived about 375 million years ago. Based on indirect evidence (paired notches of the acetabulum), we believe that in the hip joint it had two ligaments of the head of femur, in Latin called ligamentum capitis femoris (LCF). A similar anatomy of the hip joint is preserved in the salamander. Illustration Tiktaalik roseae is the first animal to have a LCF A) 3D model of the right pelvic bone of the fish Tiktaalik roseae (fragment of a screenshot:  media.hhmi.org ), where we depicted the dissected anterior LCF (lig.cap.fem.ant.) and posterior LCF (lig.cap.fem.post.), that are attached to the corresponding notches of the acetabulum ( inc.ac.ant. & inc.ac.post.).  Below the pelvis is a photograph of our model of the Tiktaalik roseae femur with fragments of two LCFs (a fossil femur of Tiktaalik roseae has not yet been discovered).
