S-osteotomy with lengthening and then nailing compared with traditional Ilizarov method

Abstract

Purpose The purpose of this study was to explore the clinical effect of the novel method combined longitudinal S-osteotomy and Lengthen And Then Nail (LATN) technique for leg lengthening and compare with the classic Ilizarov method. Methods This retrospective study was performed from March 2008 to April 2012. A total of 176 leg lengthenings (88 consecutive patients) were performed at our institution. The mean duration of follow-up was 2.2 years (range, one to four years). In group A, 78 tibial lengthenings were performed with longitudinal S-osteotomy and LATN technique. In group B, 98 tibial lengthenings were performed with the classic method. The final gain in length, mean surgical time for bilateral tibial osteotomy, the external fixation index and the radiographic consolidation index were calculated and compared. The complications encountered during operation and follow-up were documented. Results There was no significant difference in the final gain in length between the two groups. Mean surgical time in group A (130.05±6.60 min) was significantly longer than that in group B (91.4±6.61 min; P<0.05). External fixation index in group A (21.02±3.16 days/cm) was significantly lower than that in group B (76.19±8.32 days/cm; P<0.05). Consolidation index was significantly lower (more rapid healing) in group A (43.38±5.35 days/cm) than that in group B (76.19±8.32-days/cm; P<0.05). There was a significant difference in pintract problems and axial deviation between the two groups. Conclusion The novel method combined longitudinal Scorticotomy and LATN technique safely reduces the consolidation time, rate of pin-tract problems and axial deviation during leg lengthening, compared with the classic Ilizarov method.

Comparison of Intramedullary Nail Versus Conventional Ilizarov Method for Lower Limb Lengthening: A Systematic Review and Meta‐Analysis

“…A total of 89 titles and abstracts were preliminarily reviewed, of which 4 studies eventually satisfied the eligibility criteria (Fig. ). These studies included one RCT, two clinical controlled trials and one retrospective cohort study.…”

Results of deformity correction in children with X-linked hereditary hypophosphatemic rickets by external fixation or combined technique

“…b Bisegmental polyfocal osteosynthesis with the Ilizarov frame of the left lower limb associated with intramedullary nailing (retrograde in the femur and ante-retrograde in the tibia) and radiograph of the limb at the beginning of ambulating with full weight bearing, at age 4.5 years. c Similar type of osteosynthesis performed at age 5.5 years for deformity correction of the right lower limb d Radiograph of the lower limbs in 20 months after the second stage of operative treatment; there is valgus shape of the right lower limb and varus of the left lower limb e At age of 12 years, development of valgus deformities at the level of distal metadiaphysis of the right femur and proximal metadiaphysis of the right tibia, on the left femur a varus deformity of distal metadiaphysis (mLDFA 93°) was noted, but there were no recurrent deformities at the level of reinforced bone areas conditions from a point of view of accuracy of deformity correction, abilities of gradual controlled correction of all deformity components in a postoperative period at a level of femur and tibia, absence of interference in growth cartilages, and absence of inhibition of the following segment growth in length [14,17,19,[34][35][36].…”

Treatment of Post-Traumatic Femoral Discrepancy With PRECICE Magnetic-Powered Intramedullary Lengthening Nails

“…Alternatives include lengthening over nail, 6 lengthening over plate, 7 lengthening and then plating, 8 and lengthening and then nailing. 9 However, serious complications such as deep infections, refractures, and axial deviation were still observed. 10–12 …”
