Tóm tắt

Objective: we perform this study with the following objective: Studying the initial stability of a new type of hip replacement-spiron short stem. Subjects and methods: Experiments to determine the deformability, elasticity and force capacity of the femur were used for the short stem and the long stem replacement corresponds to the original femur without the prosthesis. Along with that, we were evaluated  short-term results of treatment for 70 patients with 92 Spiron hips replacement  in the Institute of Trauma and Orthopedic-108 Military Central Hospital, from 2012 to 2016. Results: The analysis results showed that the Spiron short stem prosthetic had a significantly smaller displacement in the mid-frost bond than the Zweymuller long stem prosthesis. Clinical research: Harris’s score was 45.2 (± 2.4) before surgery. At the final examination time Harris’s score was 91.4 (± 2.5). The rate: very good (75.0%), good (17.4%), average (3.3%), poor (4.3%). There are 02 cases early stem loosening had to stem revision surgery (2.2%). Conclusion: These results show the good initial fixed ability as well as stability when replaced by the Spiron stem.
