“…O método da distração osteogênica difundido por Ilizarov (2) , nos anos 80, usando um fixador externo circular, proporciona liberdade funcional ao paciente, corrige as deformidades e o encurtamento e cura a infecção, por meio da ressecção do osso desvitalizado seguida do transporte gradual de um fragmento ósseo após corticotomia (5,(11)(12)18) . Autores afirmam que, para erradicar a infecção, há necessidade da ressecção dos tecidos desvitalizados e infectados (5)(6)10,13,18) .…”

“…Preservation of periosteum as the main source of blood supply is critical [46,[75][76][77][78][79][80][81]. Its disruption significantly decelerates bone formation [75,82].…”

“…Its disruption significantly decelerates bone formation [75,82]. Ilizarov and others firmly recommended corticotomies to preserve medullary blood flow [26,80,83]. However, this is difficult to perform and experimental work revealed that complete bone separation (osteotomy) is equally effective [76,82,[84][85][86][87].…”

“…Intra-membranous bone formation is the underlying biological process of callotasis [8,26,27,78,80,93,100,101]. Typically, it evolves in defined radiological and histological zones: central type I collagen with adjacent vascular periosteal and endosteal ingrowth comprising osteoblasts depositing osteoid along the collagen bundles, laterally neighboured by longitudinal columns of mineralised bone stretching out parallel to the distraction forces and eventually bridging transversely [8,100,[102][103][104].…”

Any lower limb discrepancy may be equalised by conservative means (insoles, prosthesis and orthosis). However, their long-term acceptance is low in regard to function, costs, expenditure and appearance. Timely epiphysiodesis is the best option in uniplanar deformities with adequate remaining growth and for patients whose predicted final body height is above the 50th percentile. However, many patients present late or with multi-planar deformities, which warrant more sophisticated operative approaches. The history of surgical bone lengthening comprises 100 exciting years of struggling, development and ongoing learning. The initial strategy of acute or rapid incremental distraction had lasted almost half a century until Ilizarov recognised the benefits of biological periosteum-preserving osteotomies and incremental lengthening at slow rates (1 mm/day) at a 4 × 0.25-mm daily rhythm, well appreciated as callotasis. In parallel, ring and wire constructs made complex three-dimensional axial, translational and rotational bone moulding possible. Taylor Spatial Frames—built on hexapod strut-linked platform technology as known from flight simulators—took limb correction to a more reliable, more precise and aesthetical level, all the more that the whole process became web-based. It represents state-of-the-art methodology and technology for complex, multi-plane deformities. Due to the significant risk of secondary malalignment, indications for lengthening by unilateral fixation have shrunken to moderate amounts of length disparity and uni- to bi-planar deformities in patients with still open physes. Mechanical or motorised, minimally invasively placed nails prevent muscle fixation and, therefore, ease rehabilitation, increase patient comfort and potentially shorten the overall time of sick leave and refrain from sports activities. Hence, they offer a valuable alternative for low-grade complexity situations. It remains to be proved if the significantly higher implant costs are compensated by lower treatment costs. Overall, limb lengthening, particularly in combination with multi-planar deformity correction, can still be an arduous endeavour. In any case, wise judgement of the patient’s deformity, medical and biological situation, psychosocial environment, selection of the appropriate method and hardware, as well as meticulous operating technique by an experienced surgeon are the cornerstones of successful outcomes.
