Abstract:
Background: Pilon fractures are severe distal tibia injuries from high-energy trauma, often involving joint and soft tissue damage. Despite surgical advances, long-term outcomes remain poor. This study compared quality of life and functional limitations after surgical treatment of pilon versus tibial shaft fractures using validated PROMs. Methods: This case-control study was conducted at a Level I Trauma Center. Between 2016 and 2019, 84 patients with lower leg fractures were included: 38 pilon and 46 tibial shaft fractures. Inclusion criteria were AO type 42 or 43 fractures and follow-up of ≥24 months; exclusion criteria were polytrauma (ISS > 15), ASA ≥ 3, and incomplete consent. Outcomes were assessed with SF-12, EQ-5D-5L, and VAS-FA. Data were collected 36-48 months postoperatively. Analyses included t-tests, chi-square tests, linear regression. Results: Patients with pilon fractures had significantly poorer physical quality of life than tibial shaft fractures (SF-12 physical: 39 vs. 42, p < 0.05). Mental quality of life showed no significant difference. EQ-5D-5L scores were lower in the pilon group (70% vs. 79%). VAS-FA indicated higher pain and reduced function (total: 64 vs. 76, p = 0.009). Rehabilitation duration correlated with improved VAS outcomes in pilon fractures (p = 0.008), while physiotherapy reduced pain in tibial shaft fractures (p = 0.030). Conclusions: Pilon fractures substantially impair physical quality of life and long-term function, while mental well-being remains unaffected. PROMs provide insights beyond radiological findings and should be integrated into follow-up. Further multicenter studies are required to validate these results and optimize rehabilitation strategies.
