Heterotopic ossification is defined as the formation of normal mature lamellar bone in atypical, extra skeletal tissues, commonly around the hip joint involving the abductor muscles and occasional iliopsoas muscles. Among the known causative factors are traumatic brain injury, spinal cord injury, and other trauma including iatrogenic causes such as surgery. A less common cause is exposure to pharmacologically induced paralysis involving prolonged intubation. We present a case of heterotopic ossification involving the Superior Gamellus muscle without antecedent trauma but with history of prolonged intubation who functionally improved after surgical resection.
