Abstract
|
|
|
|
Heterotopic ossification (HO) around the hip joint is not uncommon following neurological injury. Often, surgical
treatment is performed in patients with restricted motion and/or refractory pain due to grade III or IV
HO according to Brooker classification. The major complication that occurs as a result of surgical HO removal
is perioperative bleeding due to hyper-vascularization of the lesion. Here, we report a case of preoperative
embolization in a 51-year-old male patient presenting with restricted bilateral hip range of motion (ROM) due
to HO following a spinal cord injury. In the right hip without preoperative arterial embolization, massive bleeding
occurred during surgical removal of HO. Thus, the patient received a transfusion postoperatively due to
decreased serum hemoglobin levels. For surgery of the left hip, preoperative embolization of the arteries
supplying HO was performed. Surgical treatment was completed without bleeding complications, and the
patient recovered without a postoperative transfusion. This case highlights that, while completing surgical
removal for ROM improvements, orthopedic surgeons should consider preoperative arterial embolization in
patients with hip HO.
