Selected fragments of the book Bell J. The Principles of Surgery (1801). The author discusses hip injuries and the mechanism of ligamentum capitis femoris (LCF) injury. Bell's drawing and reasoning probably led 1823GerdyPN to consider the role of LCF tension in hip dislocation. Quote pp. 523-524 The acetabulum or socket for the thigh bone is formed in the centre of the greatest and firmest bone of the pelvis, named os innominatum, from its irregular shape. It is in the adult the largest and firmest bone of the pelvis, but in the child it is formed of three distinct bones, the Ilium, Ischium, and Pubis. These are joined by an intermediate cartilage, and are easily separated into distinct bones. At an early age this cartilage is prominent, and somewhat of a triangular form. The cartilage is ossified in the adult, and it being ossified, becomes more prominent, and makes a high triangular projection in the centre of the socket; this prominence gives a firmer connexio...
