[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)

Fig. 3 (A) Based on CT of the pelvis and distal femur; (B) we created a 3D model; (C) The acetabular fossa was digitally removed; (D) the fovea was identified and manually exaggerated; (E) finally, the model was subjected to standardized movements within physiological range of motion and the foveolar tracking pattern was determined. (Commons Attribution 4.0 International)

The Solar System

  The Solar System As a result of a mysterious catastrophic event about 13.8 billion years ago, the Universe was formed (2012HawkingS; 2020AghanimN_RoudierG). In it, giant cloud-like accumulations of plasma, molecules and dust became the points of star formation (2011MurrayN). A series of their generations, igniting, functioning and collapsing, led to the appearance of various chemical elements through staged reactions of nuclear fusion (1998IshkhanovBS_TutynIA). The Sun was born for at least ten million years by compressing a concentration of molecular gas and parts of the most ancient stars (2010HanslmeierA). As a result, 4.5682-4.567 billion years ago, the Solar System self-organized, at the dawn of its life consisting of a central luminary and a protoplanetary gas and dust disk (2013HazenRM). At least the oldest meteorite inclusions were fused 4.568-4.565 billion years ago, and at most three million years later, accretion of chondrite globules occurred (1995AllègreCJ_GöpelC). T...

  A fragment of the manuscript of the translation of Josephus Flavius' Antiquities of the Jews ( Ἰουδαϊκὴ ἀρχαιολογία / De antiquitate iudaica) into Latin by Rufinus Aquileiensis. The translator worked approximately between 344 and 411 in the Roman Empire. His work was rewritten between 1150 and 1199 in Northern France. In Josephus's translation of Antiquities of the Jews, ligamentum capitis femoris (LCF) is referred to as «neruum».
