Abstract
An intramedullary lengthening device includes a housing and a distraction shaft. The intramedullary lengthening device is placed within a cavity of two bone sections (either already separated or purposely separated for insertion of the device). The distraction shaft of the intramedullary lengthening device is attached to the one of the bone sections using, for example, one or more attachment screws. The housing of the intramedullary lengthening device is attached to the second bone section using, for instance, one or more attachment screws. Over the treatment period, the bone is continually distracted, creating a new separation into which osteogenesis can occur. In one embodiment, the intramedullary lengthening device includes an actuator and an extension rod, which can be attached to one other.
