Case: This is a case of a 6-year-old patient diagnosed with Gorham-Stout disease (GSD), a rare lymphangiogenic skeletal disorder, localized to the left femur. Initial nonoperative treatment with pharmaceuticals and bracing was unsuccessful. We describe a definitive operative treatment with radical femoral resection and a modified rotationplasty technique through a tibiopelvic rotational hip arthroplasty. At 2-year follow-up, the patient was able to walk with a prosthetic device. Conclusion: The use of this modified rotationplasty technique is an effective treatment option for patients with femoral GSD to improve function and quality of life.
