Heterotopic ossification (HO) presents as calcification of soft tissue around traumatic or neurologically affected joints. Currently, the etiology of HO is unknown.

Patients typically are asymptomatic, and the problem usually is incidentally discovered on radiographs of a joint that is losing ROM.

Clinically, HO can present with local erythema, warmth, induration, and swelling. Cailliet reported that the onset can occur as early as 2 weeks or as late as 3-6 months poststroke. [10]
