RESUMO
BACKGROUND: We aimed to evaluate the clinical and radiological results of total elbow arthroplasty (TEA) performed for trauma sequelae in patients <45 years of age. METHODS: This retrospective study included 63 patients aged <45 years who underwent TEA between 2005 and 2017 for previous elbow injuries. The average follow-up period was 5.23 years (range, 2-13 years). The clinical analysis included limb function according to the Mayo Elbow Performance Score, Oxford Elbow Score, and range of motion. The degree of radiolucency was determined using plain radiographic images. RESULTS: The average amplitude of elbow flexion/extension increased from 49.1 ± 36.7 to 98.7 ± 28.2 (P < .01), and the average amplitude of elbow pronation/supination increased from 87.2 ± 52.3 to 118.7 ± 26.3 (P = .02). Functional results improved from 21.4 ± 13.1 to 67.3 ± 14.5 (P < .01) on the Mayo scale, and those measured according to the Oxford scale improved from 15.4% ± 7.0% to 28.0% ± 10.6% (P < .01). Complications were observed in 16 (32.7%) patients. Among them, 10 patients (20.4%) required revision elbow arthroplasty with replacement of implant components. The overall 5-year implant survival rate was 79.4% (95% confidence interval: 63.4-91.2), and the 10-year survival rate was 77.5% (95% confidence interval: 59.3-88.2). CONCLUSION: TEA allows restoration of the full range of motion in the elbow joint and significantly improves limb function in most cases. However, the low survival rate of implants and high incidence of complications do not permit TEA to become a routine intervention for treating post-traumatic consequences in young patients.
