Abstract
Introduction and purpose: The treatment of proximal humerus fractures is still controversial in terms of the surgical approach to be used and even of whether surgery is indeed necessary or not. The purpose of this study is to assess the functional result and the patients’ perception of their general health condition after treatment of displaced humerus fractures by means of transosseous sutures with or without the support of modified Ender nails.
Materials and methods: The study comprised a series of 40 patients (mean age: 66.21 years); 82% females /18% males. The patients had the following fracture types: 27% had two-part fractures, 60% had three-part fractures and 12% had four-part fractures and fracture-dislocations. The mean follow-up was 55.83 months (12.83-97). The final functional evaluation was carried out using the Constant score and the health perception was measured on the EuroQol-5D scale. All patients were submitted to a final radiological exam (AP and profile radiographs on the scapular plane).
Results: The mean value obtained on the Constant Scale was 74.18 in the involved arm and 84.06 in the contralateral one. As regards pain, the mean obtained was 12.57, while the value for forward arm elevation was 8.24. When comparing two age groups (> 70 vis-á-vis < 70 year olds) a significant difference was obtained with respect to Constant Scale’s global value (p 0.022). Furthermore, a significant difference was detected between the result of the EuroQol-5D scale, the global result of the Constant Scale (p 0.061), abduction (p 0.05), internal rotation (p 0.05) and strength (p 0.007). The rate of postop complications was 6% (2 surgical wound haematomas). The final radiological control revealed losses in reduction and necrosis in 9.37% and 3.03% of patients respectively.
Conclusions: (1) Good global functional results on he Constant Scale. (2) Significant differences in functional results based on patients’ age. (3) Difference in quality of life perceptions on the basis of the amount of mobility and strength obtained postoperatively. (4) Low complications rate.
