# Modified Ludloff’s medial approach for resection of heterotopic ossification of the hip following severe SARS-CoV-2 infection: a case report

## TL;DR

A patient developed hip bone growth after severe SARS-CoV-2 infection and was successfully treated with a modified surgical approach.

## Contribution

A modified Ludloff’s medial approach was successfully used for resecting hip heterotopic ossification after SARS-CoV-2.

## Key findings

- Modified Ludloff’s medial approach provided good exposure for resecting hip heterotopic ossification.
- Heterotopic ossification occurred following severe SARS-CoV-2 infection and immobilization.
- The surgical approach allowed successful removal of pathological tissue in the hip joint.

## Abstract

The coronavirus disease 2019 pandemic has significantly affected people worldwide. Herein, we present a case of massive heterotopic ossification (HO) of the right hip following severe SARS-CoV-2 infection. The exact origin of HO development is still unknown, but a critical illness, chronic immobilization and hypoxia are important risk factors. Considering the location and size of the HOs in this case, modified Ludloff’s medial approach of the hip was used. This approach allows for good exposure and access to the medial and inferior part of the hip joint and the successful extirpation of the pathologic tissue.
