Abstract
The distal femur is one of the most common sites involved by primary malignant bone tumors in the skeletally immature population. Limb salvage surgery is the mainstay of treatment since the oncological outcomes are comparable to and functional outcomes are usually better than amputation. Biological reconstruction is the treatment of choice, particularly in young patients with a favorable prognosis and whose knee joints can be spared. While limb length discrepancy (LLD) in the setting of biological reconstruction might be managed with the conventional method of distraction osteogenesis via different types of external fixators, intramedullary magnetic nails offer the advantages of excellent patient comfort and avoiding soft tissue-related complications such as pin tract infection and contracture. In this case, we present a patient operated for LLD with intramedullary magnetic nail lengthening in the setting of biological reconstruction with an inlaid vascular fibula and frozen autograft shell combination.
