  Fragments from the book Sandifort E. Descriptio ossium hominis. (1785). The author briefly writes about the attachment of the ligamentum capitis femoris (LCF). Quote p. 104 [Lat] Os ischium… … Qua spectat pelvim (a) os ischion æquabile est, modice cavatum, ab exteriore profunde sinuatum (b). Sinus hic, quem acetabulum vocant, maximus, sere rotundus, est, dividique potest in partes duas, alteram semilunarem quodammodo, cartilagine tectam (c), hinc æquabilem, alteram altius excavatam, asperam (d), glandulæ muciparæ sedem præbentem, & educentem ligamentum teres, quod capiti ossis femoris infigitur (e). … Quote p. 108-109 [Lat] Femoris os … … Caput magnum, globosum, cartilagine lævi incrustatum, oblique positum (b), id est, sursum introrsumque tendens, magnitudine & figura cum acetabulo (i) congruens, intra illud admittitur, illique alligatur per ligamentum teres, quod firmiter adhæret ab altera parte acetabulo, ab altera sinui profundo, inæquabili, qui in dicto capite est (k...

Homo floresiensis

  HOMO FLORESIENSIS Homo floresiensis lived on the island of Flores (Indonesia) 190-50 Kya (2016SutiknaT_RobertsRG). The ancestor of this species is «suspected» to be the Asian subtype Homo erectus, which arrived from the mainland about 800 Kya (2009LyrasGA_DeVosJ). The anatomy of Homo floresiensis is less similar to Homo habilis (2008Gordon_WoodB). Homo floresiensis Author: Cicero Moraes et al.  (Arc-Team)  ; source: wikimedia.org   collection (license CC BY 4.0, no changes). Among the discovered remains of a female Homo floresiensis  ( humanorigins . si . edu )  there is a relatively well-preserved left pelvic bone (LB1/7). It has a « typically human » acetabulum (2009JungersWL_DjubiantonoT:Fig.3). The acetabulum has a complete fusion of the three bones that form it and is not hypoplastic (2012BrownP:Fig.4). The acetabular fossa is rounded and deep, continuing downwards and forwards as a wide acetabular notch. This area is the site of attachment and func...

Catalog. Arthroscopic reconstruction

  Introduction  Currently, ligamentum capitis femoris (LCF) reconstruction using arthroscopic technologies is considered promising. According to the literature available to us, the first such operation was performed by Marc J. Philippon, which he first reported on in May 2006 (2006PhilipponMJ). Until now, reconstruction of LCF using minimally invasive technologies has not yet become widespread. The long-term results of arthroscopic LCF repair are still uncertain due to insufficient number of surgical procedures performed and short follow-up period (2014O'DonnellJM_SinghPJ).

The First Animals

  THE FIRST ANIMALS According to molecular clock data, the separation of the Animal Kingdom from the Plant Kingdom occurred 1609±60 Ma (2004HedgesSB_ShoeJL). Molecular estimates indicate that the last common ancestor of multicellular representatives of the fauna (Metazoa) was Neoproterozoic, most likely younger than 800 million years (2015PisaniD_LiuAG). Biomarkers of metazoan living systems identified in sedimentary deposits indicate their presence in the seas since the Cryogenian period (2018ZumbergeJA_SummonsRE), which began around approximately 720 Ma (2023CohenKM_CarN). Multicellular animals were part of early Ediacaran ecosystems and are found below layers dated to 632.5 ± 0.5 Ma (2007Yin_LHuJ). The oldest fossil of a multicellular organism resembling a sponge (Porifera) is about 600 Ma (2015YinZ_TafforeauP). The last Neoproterozoic glaciation (about 582 Ma) coincides with the appearance of complex organisms in the fossil record (2007BowringSA_AllenPA). Ev...

Tiktaalik roseae

  TIKTAALIK ROSEAE The first truly tetrapod animal (Limbed tetrapods) is recognized as the lobe-finned fish Tiktaalik roseae (clade Elpistostegalia), discovered in rocks aged about 375 Ma (2006DaeschlerEB_JenkinsJrFA; 2008ShubinN; 2017ShubinN). Discoveries in recent years have allowed us to place the taxa of early tetrapodomorphs in the following order: Tinirau, Eusthenopteron, Megalichthys, Panderichthys, Qikiqtania, Tiktaalik, Elpistostege, Parmastega, Ventastega, Acanthostega, Elginerpeton, Ymeria, Ichthyostega (2022StewartTA_ShubinNH). The closest ancestor of Tiktaalik roseae, the fragments of the skeleton of which are relatively well preserved, is Panderichthys. Reconstruction of the prehistoric fish Pandericthys Author Tyler Rhodes; original in the  wikipedia.org   collection (license CC BY-SA 3.0, no changes). The shape of the skeleton of the pectoral fin and shoulder girdle suggests that Panderichthys rhombolepis "walked" (2006AhlbergPE_ClackJA). At the very least...
