1783BonnA

 

The author provides a description of cases of absence of the ligamentum capitis femoris (LCF) and the fossa of the femoral head. Analyzing observations made by Andreas Bonn, we understand that the absence of LCF is associated with severe pathology of the hip joints, presumably congenital. Thus, the observations are not a variant of the norm. To denote the LCF, the author used the terms: ligamentum teres, tereti ligamento, and ligamentorum teretium. This work was cited by subsequent researchers of LCF: 1820PallettaGB, 1841StanleyE.

Femur finiftrum (XLIII.), huic coxæ refpondens, caput habet depresfum et complanatum, parte fuperiore et exteriore, qua libere intra novam fpuriamque articuli capfam movebatur, tuberofum, cartilagine tenui obductum; parte inferiore, qua coxa éi innitebatur, hinc inde fibrofa, aut eburneæ foliditatis atque politure. Sinus, cui affigatur ligamentum teres dictum, nullus confpicuus. Trochanter minor degeneravit in planitiem osfeam, quæ area ifchii fupra defcriptæ refpondet, osfium mutuo attritu efficta. Femoris dextri (XLII.) caput minus depresfum, conoideum, elongatum, vix cartilaginofum, parte fuperiore libera tuberofum; parte interiore et inferiore, qua ad ilium movebatur, complanatum, porofum. Sinus pro tereti ligamento deficit. Neque, intra acetabula coxarum, ullum horum ligamentorum teretium veftigium reperitur. Recenten pelvim cum accepimus, coxa finiftra liquori fpirituofo condita.	The left femur (XLIII.), corresponding to this joint, has a flat and elongated head, in the upper and outer part of which, where it freely moves within the new and empty joint capsule, there is a protuberance covered with thin cartilage; the lower part, on which its thigh rested, was at places fibrous or solid and polished like ivory. The sinus to which the so-called round ligament attaches is clearly not visible. The lesser trochanter has turned into a flat surface corresponding to a specific area of the ilium, worn by mutual friction of the bones. The head of the right femur (XLII.) is less flat, conical, elongated, barely covered with cartilage, with a protuberance in the upper free part; the inner and lower parts, where it contacted the ilium, are flat and porous. The sinus for the rounded ligament is absent. None of these rounded ligaments are found inside the acetabular cavities. After obtaining a fresh pelvis, the left femur is immersed in alcohol solution.

XLIV. XLV. XLVI. XLVII. Osfa coxarum atque, femora fenis, a pueritia fua utroque pede claudi. Collum femoris finiftri (XLVII.) in caput amplum et globatum defmit, cujus fuperficies, nunc cortice naturali lævi orbata, tota fere fibrata eft, ante macerationem crasfa cartilagine obducta erat, et ad finum coxa accommodata. Sinus, cui ligamentum teres affigitur, nullus.	XLIV. XLV. XLVI. XLVII. The bones of the pelvis and femur, from childhood, suffer from deformity in both legs. The neck of the left femur (XLVII.) transitions into a wide and round head, the surface of which is now devoid of natural cortex and largely composed of fibers; before maceration, it was covered with thick cartilage and adhered to the pelvic sinus. The sinus to which the round ligament attaches is absent.
