JUN 27, funny bones: heterotopic ossification (HO)


HETEROTOPIC OSSIFICATION, myositis ossificans,   (OEDILF #T527921)

Heterotopic formation,

Extra-skeletal ossification: 

Post trauma, new bone

Seems to form on its own -- 

Interferes with your re-ambulation.

Rarely, joints get encased as in stone.

Dr. G.H. and Giorgio Coniglio, 2022

Usually asymptomatic, new bone formation in extra-skeletal sites seems to occur after physical or surgical trauma, particularly in the lower limbs following joint replacement. Occasionally, within several weeks after the inciting episode, tenderness and swelling near major joints may occur, needing to be differentiated from venous blockage, and requiring bone scanning for detection, as initial radiographs may be negative; this variant syndrome is known as myositis ossificans. Rarely, in progressive cases, surgery is eventually required to allow normal mobility at affected joints.
