# Robot-assisted excision with intervertebral foramen endoscopy in the treatment of osteoid osteoma of femoral neck: a case report

## TL;DR

A new robotic method was used to successfully treat a rare case of osteoid osteoma in a difficult-to-reach location in a young patient.

## Contribution

Introduces robot-assisted intervertebral foramen endoscopy for treating femoral neck osteoid osteoma.

## Key findings

- The robotic method successfully excised the lesion without complications.
- Symptoms were completely resolved with no recurrence observed.
- The technique shows potential for treating hard-to-reach orthopedic conditions.

## Abstract

The diaphyseal or metaphyseal of the long bone is a common location for osteoid osteoma(OO), however, the femoral neck lesion is rare. There proves an original method to treat this disease.

An 11-year-old female, complained of a limp and right hip pain. Based on her history, and clinical and imaging examination, she was diagnosed with OO. Given that the location of the lesion is on the back of the femoral neck within the hip joint, and the local anatomical structure is close to the sciatic nerve and medial circumflex femoral artery, we performed robot-assisted excision with intervertebral foramen endoscopic.

This innovative treatment completely and successfully eliminated her symptoms without recurrence at the last follow-up. Our research suggests that this technology can be widely applied to the treatment of OO at some sites difficult to reach, beyond other orthopedic conditions.
