Hoy muchos cirujanos usan una de las dos opciones con la idea de que reduce el riesgo, pero esa creencia no está comprobada con estudios aleatorizados. Para un jubilado que va a operarse, la diferencia podría importarle. Este documento no tiene resultados: solo fija las reglas con las que se analizará el ensayo.","quienFirma":"Ensayo REDEP (institución no identificada en el texto)","confianza":"preprint","consulta":null},"sello":{"hash":"fa7ccbd9fa3cd60783751f7a3687117666201618a641c86b3c71d13f6e5a9bbb","sello":"ca334d502f9a58d17938bda45780baa98876f622456e6d5bf61857ea6ae448d6","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6589557,"aleatorio":"074102cb3486d8030e85bccc146ee3d40bd144f9cae3dc815e4783f75ca0035b","tiempo":"2026-10-27T16:15:30.000Z"},"nist":{"cadena":2,"pulso":2001772,"salida":"0E703280D2ECB99CF237148891BE4B05125CA4A9FA93BA99C93DE108693398FC1C1436A917C2E942D3FD99D4FACCDDC40E70589522F4EEDE9B18514294B0BD55","tiempo":"2026-10-27T12:55:00.000Z"},"noAntes":"2026-10-27T16:15:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 27 16:15:37 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Statistical Analysis Plan for the REDEP study: Effectiveness of dual-mobility cups for preventing dislocation after primary total hip arthroplasty by a posterolateral approach compared to unipolar cups in elderly patients","descripcion":"Periprosthetic hip dislocation is a frequent complication after primary total hip arthroplasty. Observational studies suggest that dual mobility cups may reduce dislocation risk to approximately 1%, but definitive randomized evidence supporting their routine use in primary total hip arthroplasty is absent. The REDEP trial is the first prospective, randomized controlled trial that compares dual mobility cups with unipolar cups in patients [≥]70 years who electively undergo primary total hip arthroplasty via a posterolateral approach. The primary objective of the trial is to determine the difference in the number of patients who suffer a periprosthetic dislocation of the hip within 1 year a","pubDate":"2026-10-27","url":"https://www.medrxiv.org/content/10.64898/2026.10.27.26364841v1?rss=1"},"indexado":"2026-10-27T16:14:26.625Z"}}
