Classification of Joints with Flexible Elements

The classification of joints with flexible elements was first proposed by A.S. Arkhipova in 2016 and presented at conferences in 2016-2017 (2017АрхиповаАС).

Joints with flexible elements are divided by the author into detachable and non-detachable, three-axis, two-axis, and single-axis. Each can contain in various combinations one or more external and internal flexible elements - analogs of joint ligaments, including the ligamentum capitis femoris (LCF).

Conditional designations of joints with flexible elements using the example of a ball joint:


Detachable ball joint with an internal flexible element


Non-detachable ball joint with an internal flexible element

Detachable ball joint with an external flexible element

Non-detachable ball joint with an external flexible element

Detachable ball joint with both internal and external flexible elements


Non-detachable ball joint with both internal and external flexible elements

Flexible elements can be used to secure the head in the socket, as well as to change the trajectory and range of motion of the joint. The length of the flexible elements and the location of their attachment points play an important role. Joints with flexible elements can be used inin pedipulators of walking machines, robots, and exoskeletons, as well as in endoprosthetics of human and animal joints.

  On the Book of Genesis translated into Old Slavonic by Cyril and Methodius ( 862-885 ). Presumably, the translators used the Glagolitic alphabet, less likely the Cyrillic alphabet.

Classification of Functions of LCF

Version : 20240224 Introduction On the biology, the common meaning of 'function' is that of role, effect, or transformation rule (1994MorenoA_Fern´andezJ). The function of ligamentum capitis femoris (LCF) is still unknown (2009LampertC) and the ligament itself continues to bewilder and fascinate orthopaedic surgeons (2020Rosinsky_DombBG). The largest collections of opinions on the function of the LCF are contained in our works (2004 Архипов - БалтийскийСВ ; 2018,2023 АрхиповСВ ). The classification of the function of the LCF necessary to determine the directions for further study of this structure, the choice of goals and methods for its surgical recovery. The reconstruction of the LCF without restoring specific functions to solve a clearly defined clinical and biomechanical problem is nothing more than a cosmetic procedure. The proposed classification based on experimental and clinical studies of the author, as well as because of an analysis of literary sources. All the selec...

Fragments from the book Haller A. Disputationum anatomicarum selectarum. Vol. VI (1751). The author cites an observation from the work of Saltzmann J, Nicolai HA. Decas observationum illustrium anatomicarum (1725) in which a case of absence of ligamentum capitis femoris (LCF) from two sides is described. Quote p. 694. [Lat] Observ. VII. Non rationi solummodo sed & experientiae repugnat istorum assertum, qui luxationem ossis femoris fractura facilius contingere asserunt.

Australopithecus afarensis

  AUSTRALOPITHECUS AFARENSIS In 1735, Carl Linnaeus (1707-1778) placed humans as a species «Homo nosce te ipsum» in the order Anthropomorpha along with monkeys and sloths (1735LinneC). In a publication in 1758, the naturalist transferred humans to the order Primates (1758LinneC). Today, humans and chimpanzees are united in the tribe Hominini, as descended from a common ancestor (2001GrovesCP). It has been established that the chromosome that distinguishes humans from monkeys was formed before 4.5 Ma (2022PoszewieckaB_GambinA). The hominin subfamily Sahelanthropus tchadensis lived in the Republic of Chad (Central Africa) from 7.2±0.31 to 6.8±0.45 Ma (2008LebatardAE_BrunetM; 2012ReynoldsSC_GallagherA). Reconstruction of its musculoskeletal system showed that the creature could have been an upright bipedal primate (2005ZollikoferCP_BrunetM). Fossils of what is probably the first bipedal representative of the hominid family Orrorin tugenensis, lived 6.1-5.7 Ma and still retained adapta...
