Clinical observations on surgical details of resection of heterotopic ossification at the hip in traumatic brain-injured adult.

Heterotopic ossification (HO) complicated with neurovascular bundle can be a very challenging operation. Preoperative planning before any HO resection is imperative. Plans to reconstruct nerve or artery should be in place. A case study is presented that involved a large bone mass of HO in hip joint which enclosed the sciatic nerve. Preoperative planning, microsurgical techniques, and equipment necessary for this complicated surgical procedure are reviewed.
