Objective: The aim of this study was to assess and compare the clinical, radiological, and functional results of patients treated with FITBONE or PRECICE nails due to deformity and length discrepancy in their lower extremities.
Methods: This retrospective cohort study included 41 patients with length discrepancy and deformity in their lower extremities, who underwent limb lengthening surgery with either FITBONE (group F) or PRECICE (group P) nails between 2010 and 2020. The mean postoperative follow-up period was 15.95 ± 4.75 months in group F (20 patients) and 20.48 ± 7.57 months in group P (21 patients). Lower extremity mechanical and anatomical axes were measured on x-rays preoperatively and at the end of treatment. Consolidation and distraction indexes were also calculated to assess bone healing. Lower Extremity Functional Scale test was used to evaluate functional outcomes and quality of life.
Results: Neither of the treatment methods caused deviations in the mechanical axes and femoral distal angles (P > .05). No statistically significant difference in consolidation and distraction indexes was found between the groups (P > .05). Postoperative complications were seen in 3 of the patients in group F and 4 of the patients from group P. There was no significant difference in Lower Extremity Functional Scale scores between groups (P = .425).
Conclusion: This study has demonstrated that treatment with both the FITBONE and PRECICE nails resulted in improved physical and emotional functional outcomes. Both nails had similar radiographic results, complication rates, high patient compliance, and good cosmesis.
Level of Evidence: Level III, Therapeutic Study.
