Purpose: Although bilateral lower-limb lengthening has been performed on patients with achondroplasia, the outcomes for the tibia and femur in terms of radiographic parameters, clinical results, and complications have not been compared with each other. We proposed 1) to compare the radiological outcomes of femoral and tibial lengthening and 2) to investigate the differences of complications related to lengthening.
Materials and Methods: We retrospectively reviewed 28 patients (average age, 14 years 4 months) with achondroplasia who underwentbilateral limb lengthening between 2004 and 2012. All patients first underwent bilateral tibial lengthening, and at 9–48 months (average, 17.8 months) after this procedure, bilateral femoral lengthening was performed. We analyzed the pixel value ratio (PVR) and characteristics of the callus of the lengthened area on serial radiographs. The external fixation index (EFI) and healing index (HI) were computed to compare tibial and femoral lengthening. The complications related to lengthening were assessed.
Results: The average gain in length was 8.4 cm for the femur and 9.8 cm for the tibia. The PVR, EFI, and HI of the tibia were significantlybetter than those of the femur. Fewer complications were found during the lengthening of the tibia than during the lengtheningof the femur.
Conclusion: Tibial lengthening had a significantly lower complication rate and a higher callus formation rate than femoral lengthening. Our findings suggest that bilateral limb lengthening (tibia, followed by femur) remains a reasonable option; however,we should be more cautious when performing femoral lengthening in selected patients.
