Vástagos cortos versus convencionales en artroplastia total de caderanuestra experiencia

Zusammenfassung

Objetives: To evaluate the incidence of complications and the quality of life after surgery in two groups of patients undergoing total hip arthroplasty not cemented with a short stem and with a standard uncemented stem. Material and Methods: A retrospective study was performed in a to-tal of 106 total hip arthroplasties implanted in the University Hospital of Puerto Real between 2011 and 2015. The following variables are compared: hospital stay, need for blood transfusion, mechanical complications, need for revision for any reason , radiological parameters (calcar resorption, subsidence, postsurgical dysmetria, remnant neck metrics) and anterior thigh pain in two homogenous groups of 63 conventional uncemented ana-tomical stems with 43 short stems of metaphyseal stabilization and partial femoral neck preservation (“Partial collum”), implanted by the same surgeon. For the statistical analysis, T Student was used for the analysis of quantitative variables and Chi-square for qualitative variables. Results: The results show statistically significant diffe-rences (p <0.05) in terms of postsurgical hospital stay variables, periprosthetic fractures, dysmetria, mechanical complications and metrics of the remaining neck. Conclusions: The results support the use of short stems of metaphyseal stabilization and preservation of the greater trochanter in young patients with adequate bone quality given the clinical advantages they imply.
