Schiedel et al. [34]	Prospective	26 total 20 femoral 6 tibial	97%a	37 mm	4 total 2 nail breakages 1 nail failed to function 1 premature consolidation

^aAccuracy measured after total lengthening; accuracy = lengthening achieved/desired lengthening

^bMeasured accuracy of distraction at each postoperative visit; accuracy = 100—absolute % error of distraction
