Abstract
SUAREZ-QUINTERO, A; FERNANDEZ-DOMINGUEZ, JM and LOPEZ-SORROCHE, E. Functional results after shoulder hemiarthroplasty for proximal humerus fracture: experience in our center. Acta ortop. mex [online]. 2022, vol.36, n.6, pp.359-366. Epub Jan 19, 2024. ISSN 2306-4102. https://doi.org/10.35366/111869.
Introduction:
shoulder hemiarthroplasty is being relegated as a treatment for non-osteosynthetic proximal humerus fractures. Our objective is to analyze the functional results of patients treated with hemiarthroplasty for this reason in our hospital.
Material and methods:
cross-sectional descriptive study that includes patients operated between February 2016 and November 2021; 24 patients, with an average follow-up of 44.6 months. Active joint balance, the Constant-Murley test, the DASH questionnaire and current pain (VAS) were collected. The radiographic parameters analyzed were the number of fracture fragments and the consolidation of the tuberosities.
Results:
a mean of 71.65 ± 13.75 was obtained in the Constant-Murley and 18.14% ± 13.92 in the DASH. For shoulder flexion, the mean was 108.75o ± 41.26; 104.5o ± 43.68 for abduction and 33o ± 14.73 for external rotation. About internal rotation, 60% of the patients reached the scapular plane. Average VAS was 1.25 ± 1.74. Consolidated tuberosities in 90.5%. There were no significant differences comparing the Constant-Murley test, DASH or rotations between both, over and under 65 years old group of patients. Those over 65 years of age obtained a mean flexion of 125.91o ± 26.82 whereas those under 87.78o ± 26.82 (p = 0.038). The mean abduction in those over 65 was 125.45 ± 28.94 vs 78.89 ± 46.29 in the young group (p = 0.012).
Conclusion:
hemiarthroplasty provides quality of life with acceptable functionality and good pain control, therefore it should continue to be an alternative to consider in selected patients.
