1586PiccolominiA

Fragments from the book Piccolomini A. Anatomicae praelectiones (1586). One of the first discussions of the biomechanics of the ligamentum capitis femoris (LCF) with a description of its shape, mechanical properties and attachment.

Quote p. 378-379.

[Lat]

De femoribus.

Hoc rotundum & magnum femoris caput, intruditur in magnum coxendicis acetabulum; a cuius medio emergit vinculum teres ac validissimum, femur cum coxendice copulans, & hanc articulationem firmissimam stabiliensis.

…

Cur ex animalibus progressiuis, alia recta, alia prona incedunt progredumtutue? Hanc varietatem efficit vatra ligamenti rotundi ac validi e capite femoris in acetabulum inserto. Nam si inserutur versus superiotem acetabuli partem, recta progrediuntur animantia, vt homo, si versus lateralem, prona incedunt, vt bos, equus. Qud sit, vt ille faciem celsam sit sortitus caelum suspicientem, menti commodiu sinseruientem; haec vero deptessam, terram despicientem, a qua dumtaxat corporis alimenta capessaant.

Translation

[Eng]

On the thigh bones.

This round and large head of the femur is inserted into the large acetabulum of the pelvis; from its middle comes a round and very strong ligament that connects the femur to the pelvis, which makes this joint very stable.

…

Why among walking animals do some move upright and others obliquely? This difference arises from the tension of a round and strong ligament inserted from the head of the thigh bone into the acetabulum. For if it is attached to the upper part of the acetabulum, animals walk upright, like a man; if to the side, they move obliquely, like a cow or a horse. As a result of this, those [animals] whose face is raised up and directed towards the sky are better adapted to mental actions than those whose face is lowered, turned towards the earth, from which alone they receive food for the body.

INFERIOR PORTAL FOR HIP ARTHROSCOPY: A PILOT STUDY PART 1. Background and Hypothesis Arkhipov S.V., Independent Researcher, Joensuu, Finland Abstract: The article presents, theoretically and graphically substantiates the technique of a new arthroscopic approach to the central compartment of the hip joint. It is proposed to introduce the optical system of the arthroscope from below through the acetabular notch without traction. Similar approaches were used for puncture, arthroscopy, arthrography, and arthrotomy of the hip joint. Diagnostics using the described lower portal will exclude complications caused by distraction of the leg and compression of the perineal support during surgery. CONTENTS PART 1.

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 ).
