Classification of Neoplasms of the LCF

Version: 20240228

Reports on neoplasms of the ligamentum capitis femoris (LCF) are scarce. Among them, we can distinguish malignant and benign neoplasms. We categorized xanthomas and synovial cysts as distinct types of pathological alterations in tissues closely tumors. Primary of the LCF tumors are possible from various types of connective tissue and theoretically from nervous tissue. Neoplasms of the ligament can also be the result of metastasis and infiltration.

Classification of Neoplasms of the LCF (Vers. 2.1.0)

1. Primary malignant tumors
Malignant chondroma
2. Primary benign tumors
Tenosynovial giant cell tumor
Pigmented villonodular synovitis
Synovial chondromatosis
Synovial osteochondroma
Fibromyxoid pseudotumor
3. Metastasis and infiltration
4. Synovial cysts
5. Xanthoma

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». The selected fragment deals with the LCF of an animal and discusses a biblical episode of its damage in a human. See our commentary at the link: 344-411Rufinus Aquileiensis [Rus].

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...

Cùm enim ligamentum illud articulum circumd ás, omnium totius corporis ligamentorum, quae articulos ambiunt, sit amplissimum; fieri potest, ut adeò cedat, ut (sicuti saepe sit) femoris caput, è suo sinu devoluatur, & in membranae illius (quae cùm erassissima sit, prae omnibus totius corporis ligamentis, nunquam vi qualicunque disrumpi potest) amplitudine seu capacitate subsistat, elongato simul & vehementer attracto, tereti illo & crasso, quod caput aliàs in suo sinu retinere solet, ligamento.
