GARABANO, Germán et al. Resultados iniciales del uso de cotilos de doble movilidad en pacientes >65 años con fractura de cadera. Análisis retrospectivo de 102 casos. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2023, vol.88, n.5, pp.520-526. ISSN 1852-7434.  http://dx.doi.org/https://doi.org/10.15417/issn.1852-7434.2023.88.5.1757.

Objective: This retrospective study aimed to assess the functional outcomes and dislocation rate in the treatment with dual mobility prostheses in patients older than 65 with hip fractures. Materials and Methods: We analyzed all patients treated between 2017 and 2021 for hip fractures in our service. We included patients older than 65 years, treated with dual mobility cups, and a minimum follow-up of 24 months. We analyzed demographic data, comorbidities, functional outcomes (Parker score and Harris Hip Score, HHS), complications (infection, dislocation, loosening), reoperations, and revisions. Results: We included 102 hip fractures (75 medial and 27 intertrochanteric) in 102 patients. Seventy-four (72.5%) were women, the mean age was 80.59 ± 6.92 years, the mean Charlson index was 4.71 (range 3-10), and ASA was 2.47 (1-4). 93.1% started walking on the second postoperative day. 94.1% presented excellent or very good outcomes according to the HHS, the postoperative Parker index did not show significant differences in comparison to the preoperative one (p < 0.05). The average follow-up was 30 months (range 24-60). There were 8 (7.84%) complications: 2 (1.9%) deep vein thrombosis, 4 (3.9%) pulmonary thromboembolism, 3 infections (2.9%), and 1 (0.9%) dislocation. The reoperation rate was 2.9%. Conclusions: We obtained acceptable functional outcomes using dual mobility cups with a relatively low dislocation rate (0.9%). This suggests that these implants are an option to consider in treating these lesions.
