Abstract
Introduction: Study of the influence of anatomical restoration on the outcome of the surgical treatment of proximal humerus fractures treated by sutures and Ender nails.
Materials and methods: 44 fractures. Mean age 64.45. 12 men and 32 women. Mean follow-up 55.83 months (12.83-97). 14 2p fractures, 27 3p and 3 4p. Functional study using the Constant Scale. Quality of life measured with EuroQol-5D. Imaging done one year after surgery: AP X-Ray, full bilateral humerus with external measurement and control CT.
Results: Mean Constant score for series: 78.98. Mean EuroQol-5D rating for the series: 0.7681. Constant scores for total humerus length: Diminished length: difference < 1 cm, 84.71; difference ≥1 cm, 56. Increased length: difference < 1 cm, 79.2; difference ≥ 1 cm, 78.67. Constant score according to distance between head and trochlea: difference +: 77,94; difference −: 82.92. Differences by age groups: < 70 years, 84.12; ≥70 years, 73.5.
Conclusions: No significant involvement of function with differences of less than 2 cm in total humerus length. No significant involvement of function for differences of less than 1 cm in head-trochlea distance. Functional differences by age groups. Best result < 70 years of age.
