Introduction: Heterotopic ossification (HO) is often described as the mature, lamellar bone formed in a non-osseous tissue. This new bone formation usually occurs between muscle planes or between muscle and joint capsule. When it surrounds a joint circumferentially, it is known as (HO) Heterotopic Ossification circumferentia articular is circumferential articularis (HOCA). HOCA of the knee has been described earlier in the literature, but this term has never been described for the hip joint in the literature.
Case Presentation: We present a case series of two such patients having HOCA of hip joints. In both the cases, there was a history of brain injury and prolonged intubation, which seems the most likely predisposing factors in the causation of HOCA in these hips.
Conclusion: We believe that in our patient, the responsible factors for the causation of HOCA could be myriad of factors such as prolonged intensive care unit (ICU) stay with mechanical ventilation and hypoxia, long-standing immobilization, and hypomobility with incomplete flaccid paralysis. The surgical excision is quite challenging, extensive and is not advisable in most cases, and they respond symptomatically to conservative methods including analgesics, bisphosphonates, physiotherapy, and radiation.
