what holds the bone ends of an amphiarthrodial joint together?
fibrocartilage
the pubic symphysis is a nonsynovial amphiarthrodial joint. the width of the pubic symphysis at the front is 3–5 mm greater than its width at the back. this joint is connected by fibrocartilage and may contain a fluid-filled cavity; the center is avascular, possibly due to the nature of the compressive forces passing through this joint, which may lead to harmful vascular disease. the ends of both pubic bones are covered by a thin layer of hyaline cartilage attached to the fibrocartilage. the fibrocartilaginous disk is reinforced by a series of ligaments. these ligaments cling to the fibrocartilaginous disk to the point that fibers intermix with it.

bullet::::2. non-union: no progression of healing within six months of a fracture occurring. the fracture pieces remain separated and can be caused by infection and/or lack of blood supply (ischaemia) to the bone. there are two types of non-union, atrophic and hypertrophic. hypertrophic involves the formation of excess callus leading to bone ends appearing sclerotic causing a radiological "elephants foot" appearance due to excessive fracture ends mobility but adequate blood supply. atrophic non-union results in re-absorption and rounding of bone ends due to inadequate blood supply and excessive mobility of the bone ends.
