Severe Symptomatic Heterotopic Ossification and Dislocation: A Complication After Two-Incision Minimally Invasive Total Hip Arthroplasty

Minimally invasive total hip arthroplasty (THA) continues to be surrounded by controversy. Some proponents argue that they are able to achieve reduced soft tissue trauma, blood loss, postoperative pain, and hospitalization time as well as a more cosmetically pleasing surgical scar. Types of complications similar to those of a more open exposure are now being reported with these techniques. One such complication is the development of severe symptomatic heterotopic ossification requiring treatment. This case report profiles a patient who required removal of Brooker stage III heterotopic ossification after a 2-incision minimally invasive total hip THA. This is the first report of this complication after 2-incision THA.
