Brief Summary

Localization of small femur lesions for resection can be challenging and may be associated with the need for significant fluoroscopic imaging and tissue dissection.

Detailed Description

This study was performed to evaluate the use of a radiopaque localizer grid along with methylene blue staining for resection of small femur lesions in children, and to determine this technique's effectiveness at reducing radiation exposure and tissue injury.
