Monofocal Compression-Distraction Osteosynthesis in a Distal Femoral Nonunion Using a Magnetic Medullary Nail: A Case Report.

ABSTRACT

CASE A 65-year-old woman presented with a malaligned, shortened supracondylar distal femoral nonunion. An acute medial closing wedge osteotomy was performed through the nonunion and compressed with a retrograde magnetically controlled intramedullary nail. Osteogenesis with sequential compression and then distraction was performed at the osteotomy site using the nail to successfully restore limb length and alignment. CONCLUSION: A magnetically controlled nail can be used to perform monofocal sequential compression-distraction osteosynthesis through a nonunion after an alignment correcting osteotomy.
