[i] Summary

Abstract of the article Stetzelberger VM, Nishimura H, Hollenbeck JF, Garcia A, Brown JR, Schwab JM, Philippon JM, Tannast M (2024). The authors found low ligamentum capitis femoris (LCF) strength in patients with femoroacetabular impingement. A Russian translation is available at this link: 2024StetzelbergerVM_TannastM.

Background: Intraarticular hip pain represents a substantial clinical challenge, with recent studies implicating lesions in the ligamentum teres as potential contributors. Even more so, damage to the ligamentum teres is particularly prevalent among young patients undergoing joint-preserving interventions. Although several studies have investigated the biomechanical attributes of the ligamentum teres, inconsistencies in reported findings and reliance on cadaveric or animal models have raised concerns regarding the extrapolation of results to clinical practice. Furthermore, there is a lack of research examining ligamentum teres biomechanics specifically within the relevant patient cohort-individuals who benefit from joint-preserving surgical interventions.

Questions/purposes: We sought (1) to determine the biomechanical properties (ultimate load to failure, tensile strength, stiffness, and elastic modulus) of fresh-frozen ligaments from patients undergoing surgical hip dislocation, and (2) to identify patient-specific factors that are associated with them.

Methods: This was an institutional review board-approved study on intraoperatively harvested ligamentum teres from 74 consecutive patients undergoing surgical hip dislocation for joint preservation (August 2021 to September 2022). After the exclusion of patients with previous surgery, posttraumatic deformities, avascular necrosis, slipped capital femoral epiphysis, and Perthes disease, 31 ligaments from 31 patients were analyzed. The mean age of the study group was 27 ± 8 years, and 61% (19) of participants were male. The main indication for surgery was femoroacetabular impingement. Standardized AP pelvic and axial radiographs and CT scans were performed in all patients for better radiological description of the population and to identify associated radiological factors. The ligament was thoroughly transected at its origin on the fossa acetabuli and at the insertion area on the fovea capitis and stored at -20°C until utilization. Specimens were mounted to a materials testing machine via custom clamps that minimized slippage and the likelihood of failure at the clamp. Force-displacement and stress-strain curves were generated. Ultimate failure load (N), tensile strength (MPa), stiffness (N/mm), and elastic modulus (MPa) were determined. Using a multivariate regression analysis and a subgroup analysis, we tested demographic, degenerative, and radiographic factors as potential associated factors.

Results: The ligamentum teres demonstrated an ultimate load to failure of 126 ± 92 N, and the tensile strength was 1 ± 1 MPa. The ligaments exhibited a stiffness of 24 ± 15 N/mm and an elastic modulus of 7 ± 5 MPa. After controlling for potential confounding variables like age, fossa/fovea degeneration, and acetabular/femoral morphologies, we found that female sex was an independent factor for higher tensile strength, stiffness, and elastic modulus. Excessive femoral version was independently associated with lower load to failure (HR 122 [95% CI 47 to 197]) and stiffness (HR 15 [95% CI 2 to 27]). Damage to the acetabular fossa was associated with reduced load to failure (HR -93 [95% CI -159 to -27]).

Conclusion: Overall, the ligamentum teres is a relatively weak ligament. Sex, degeneration, and excessive femoral version are influencing factors on strength of the ligamentum teres. The ligamentum teres exhibits lower strength compared with other joint-stabilizing ligaments, which calls into question its overall contribution to hip stability.

Clinical relevance: Young patients undergoing hip-preserving surgery are the population at risk for ligamentum teres lesions. Baseline values for load to failure, tensile strength, elastic modulus, and stiffness are needed to better understand those lesions in this cohort of interest.

1886LesshaftP

  According to the author, the ligamentum capitis femoris (LCF) reduces shocks and impacts of the articular surfaces. In addition, P. Lesshaft states an anatomical fact: the LCF is located vertically under the part of the acetabulum, which mainly bears the weight of the body. The text is prepared for machine translation using a service built into the blog from Google or your web browser. In some cases, we have added links to quotations about LCF available on our resource, as well as to publications posted on the Internet.   Über die Vorriehtungen in den Gelenken zur Milderung der mit den Bewegungen verbundenen Stösse und Erschütterungen .

1877MorrisH

An excerpt from the article by Morris H. Dislocations of the Thigh: their mode of occurrence as indicated by experiments, and the Anatomy of the Hip-joint (1877, pp. 161-170). The author noted that the ligamentum capitis femoris (LCF) is stretched during flexion, adduction, and external rotation. It was found that the LCF is always damaged in hip dislocations, is more often torn from the femur, and is rarely ruptured. Discussion of article see article 1877BrookeC .   DISLOCATIONS OF THE THIGH: THEIR MODE OF OCCURRENCE AS INDICATED BY EXPERIMENTS AND THE ANATOMY OF THE HIP-JOINT. BY HENRY MORRIS, M.A., M.B., F.R.C.S., ASSISTANT SURGEON TO, AND LECTURER ON ANATOY1 AT, THE MIDDLESEX HOSPITAL. Received January 9th-Read February 13th, 1877. RECENTLY, whilst making various dissections of the hip-joint, the usually accepted doctrine that dorsal and ischiatic dislocations of the femur occur when the thigh is in a position of adduction appeared to me as very improbable, on anatomi...

  The author discusses his observations of LCF absence in chimpanzees and orangutans.   IX. Contributions towards a more complete knowledge of the Skeleton of the Primates . By Sr. George Mivart, F.L.S., Lecturer on Comparative Anatomy at St. Mary's Hospital. Part I. The Appendicular Skeleton of Simia. Read December 13th, 1866. [Pirates XXXV. to XLIII.] Quote p. 200 It is commonly asserted that the ligamentum teres is absent in. the Orang, as also the pit for its reception on the head of the femur (1). I find no trace of the latter in either femur of any specimen, with one exception (2); but in that. exceptional specimen each femur (Pl. XL. fig. 7 i) exhibits a small but distinct depression on its head in the place occupied in other forms by the pit for the round ligament. This absence has not, as far as I am aware, been noticed in Man or the Chimpanzee; but. in the Gorilla I have sometimes been unable to detect any trace of such a fossa on the head of the femu...
