This study aims to evaluate whether changes in ankle radiological parameters following fibular head resection due tumors lead instability and/or arthritis and assess the impact of on clinical outcomes using pedobarographic analysis pain function scales. Between January 2005 2023, a total 30 patients (10 males, 20 females; mean age: 33.9±13.8 years; range, 10 67 years) who underwent proximal fibula were retrospectively analyzed. We assessed rotation axial magnetic resonance imaging (MRI), length, talar tilt angle, talotibial angle X-ray, foot load distribution through measurements, Visual Analog Scale (VAS) Musculoskeletal Tumor Society (MSTS) scores. Fibular length significantly reduced, while talocrural higher operated side. Additionally, balance maximum pressure second fifth toes (T2-5 regions) lower The VAS score was 1.5±1.4 MSTS 26.8±2.9. scores showed weak negative correlations with differences rotation, tilt, none which statistically significant (r=-0.35, -0.3, -0.1, p=0.06, 0.1, 0.62, 0.61). In contrast, positive correlation difference (r=0.45, p=0.01), other not significant. A observed between percentage resected (r=0.67, p<0.001), (r=0.73, (r=0.49, p=0.003), (r=0.66, p<0.001); this more pronounced than 30% resection. Proximal for involving leads measurements distribution. Despite these changes, outcomes, as reflected by low high scores, indicate generally favorable patient-reported outcomes.
