We present the case of a 62-year-old man who, after suffering a severe COVID infection, spent 45 days in the intensive care unit. He developed bilateral heterotopic calcifications in his hips and within a few months a complete joint ankylosis. The surgery consisted of resection of most of the heterotopic ossification using a posterolaterally surgical approach in the right hip until restoring mobility to the joint intraoperatively. It is necessary to develop studies to determine if heterotopic ossifications are related to the viral infection itself, hypoxia, the need for invasive mechanical ventilation, immobility, or other causes in order to establish a prevention strategy for this type of complications.
