Fig. 4 — a) Correlation between leg-length discrepancy and age at limb-sparing surgery. The leg-length discrepancy at the last follow-up is shown on the vertical axis, and the age at surgery is shown on the horizontal axis. b) A five-year-old boy underwent limb-sparing surgery and a two-step reconstruction from a spacer to an expandable prosthesis. Radiographs show a peri-stem fracture of the expandable prosthesis at age 15. c) Comparison of International Society of Limb Salvage (ISOLS) scores between cases with leg-length discrepancies ≥ 5 cm (n = 3) and those without (n = 32). The ISOLS score percentage is shown on the vertical axis. **p < 0.01.
