[MagicTube: new possibilities for completely internal bone segmental transport and optional lengthening : New additional module for motorized lengthening nails for treatment of large bone defects].

Segmental bone transport is an effective method of treatment for segmental defects but the previous need for external fixation constructs during the transport phase is a great disadvantage, especially in the femur. In order to avoid external fixation, a new cylindrical combitube segmental transport (CKTST, MagicTube) module for combination with a commercially available motorized lengthening nail was developed by the author. This MagicTube module enables completely internal segmental bone transport and also enables optional lengthening if needed. The concept and surgical technique of MagicTube are described, illustrated, discussed and exemplified by clinical cases involving the tibia and femur.
