Abstract

Objective: To evaluate bone union results, functional recovery, cosmetic outcomes, and patient satisfaction after tibial lengthening surgery using an external fixation frame combine with an intramedullary nail (LON). Subjects: 131 patients with short stature who underwent tibial lengthening surgery to increase height using an external fixation frame combined with an intramedullary nail at Bac Ha International General Hospital, from January 2019 to May 2024. Methods: Retrospective, descriptive, cross-sectional study without a control group. Results: There were 131 patients (61 males, 70 females), aged 18-40 years. The mean preoperative height of males was 161.61 ± 5.59 cm, and females was 150.75 ± 5.03 cm. The mean lengthening achieved was 7.11 ± 1.17 cm. The mean follow-up time was 24.37 ± 10.99 months. All tibiae were axially aligned; there were no cases of angular deformity, lateral displacement, or external or internal rotation. In 131 patients with 262 lengthening sites, all bones were well aligned; 259/262 (98.86%) bones were large, strong, and stable like normal tibial bone, while 3/262 (1.14%) had large bone defects requiring additional bone grafting. Functional recovery returned to normal as before surgery in 114/131 patients. 17/131 patients were able to walk and perform daily activities normally but still had a few minor limitations. Surgical scars were small and relatively cosmetic. All patients were satisfied with the surgical results and showed improved confidence in daily life. Conclusion: Tibial lengthening using an external fixation frame combined with an intramedullary nail provides solid bone union, good functional and cosmetic recovery, and helps improve height and psychological wellbeing in people with short stature.
