Despite various theories, the exact mechanism (etiology and pathogenesis) of heterotopic ossification remains uncertain2. Johnson first described heterotopic ossification in patients with burn injuries in 19573, but thermal injury has been reported to be one of the least common causes of heterotopic ossification, with an estimated prevalence of 1% to 3% of all patients with burn injuries1,4-6. The most common location of heterotopic ossification in patients who have sustained a burn injury appears to be the elbow, leading to stiffness and contracture; far lower rates have been reported in other regions5,7-13. Lesions of peripheral nerves as a complication of heterotopic ossification are a relatively rare phenomenon and mainly consist of compression of the ulnar nerve in the elbow region4,5,14,15.
