Abstract : Background: New bone formation in the periarticular regions of large joints is the main character of
Heterotopic ossification (HO), most commonly seen in or after spinal cord injury, traumatic injury to brain,
burn. It is rare as the complication incidence is less than 1% or less.
Case Reports: This study reports an unusual presentations of HO in a 50 year-old male with right

and non effected side after 7 months. In this case spasticity around hip flexors, adductors along with knee
extensors, along with reduced range of motion associated with pain was present. Evaluation was done with

Conclusions: Keeping in mind by seeing the present case, HO should always be kept in mind as a
differential diagnosis in all the stroke patients who present with spontaneous joint pains. Both affected
and unaffected sides may develop which has to be always kept in mind and proper early treatment has to
