HO can be conceptualized as a tissue repair process gone awry and is a common complication of trauma and surgery. Heterotopic ossification (H.O.) is a common occurrence after total hip arthroplasty (THA) with significant potential clinical ramifications. Controversy still exists regarding the exact etiology of the disorder, including possible risk factors. Heterotopic Ossification Definition:.

Significantly limited ROM of involved joint (e.g., hip should have < 50 deg ROM) for most patients, progression to joint ankylosis is the most serious complication of heterotopic ossification. Absence of local fever, swelling, erythema, or other clinical findings of acute heterotopic ossification. Symptomatic heterotopic ossification (HO) after total hip arthroplasty (THA) and total knee arthroplasty (TKA) is relatively rare. Patients at high risk for developing HO after THA include men with bilateral hypertrophic osteoarthritis, patients with a history of HO in either hip, and patients with posttraumatic arthritis characterized by hypertrophic osteophytosis. In total hip arthroplasty (THA), the articulation of the proximal femur and acetabulum is resurfaced in order to provide pain relief and restore more normal mechanics/function of the hip joint.1 Following THA, a relatively common complication is the development of heterotopic ossification (HO). Risk Factors for Heterotopic Ossification: Injury severity score (ISS) High ISS is a risk: 11%: Traumatic brain injury (TBI) Higher incidence in the spastic limbs of the patient: 11%: Spinal cord injury: Complete SCI produces more HO than incomplete SCI. Cervical and thoracic SCI produces more HO than lumbar SCI. Younger age produces more HO 1) lorio R, Healy WL.

Patients at high risk for developing HO after THA include men with bilateral hypertrophic osteoarthritis, patients with a history of HO in either hip, and patients with posttraumatic arthritis characterized by hypertrophic osteophytosis.
