La orientación del componente acetabular es un factor determinante en el éxito de la artroplastia total de cadera (ATC). Este estudio retrospectivo analiza la variabilidad de los ángulos de anteversión e inclinación acetabular en 45 pacientes con coxartrosis intervenidos por tres cirujanos con distinta dominancia (dos diestros y un zurdo), evaluando el impacto de variables como la lateralidad de la cadera, el abordaje quirúrgico y el índice de masa corporal (IMC). Los resultados mostraron que, si bien no existieron diferencias significativas entre los tres cirujanos de forma global, al analizar individualmente, los cirujanos diestros presentaron una mayor inclinación acetabular en caderas izquierdas, lo que sugiere una posible influencia de la lateralidad y la percepción espacial. En cambio, el cirujano zurdo no mostró diferencias por lado intervenido. El abordaje anterior se asoció con una mayor anteversión acetabular, especialmente en cirujanos diestros, sin diferencias en la inclinación. En cuanto al IMC, se observó una mayor inclinación en pacientes con obesidad, aunque de forma variable entre cirujanos. No se halló relación significativa entre la dominancia del cirujano y la orientación del componente cuando se comparó el lado dominante de diestros y zurdo. Estos hallazgos subrayan la importancia de considerar la lateralidad, el abordaje y el IMC en la planificación quirúrgica de la ATC. Se requieren estudios adicionales con mayor tamaño muestral y seguimiento clínico para evaluar su impacto en complicaciones postoperatorias como la luxación.
The orientation of the acetabular component is a determining factor in the success of total hip arthroplasty (THA). This retrospective study analyzes the variability of acetabular anteversion and inclination angles in 45 patients with hip osteoarthritis treated by three surgeons with varying dominance (two right-handed and one left-handed), evaluating the impact of variables such as hip laterality, surgical approach, and body mass index (BMI). The results showed that, although there were no significant differences between the three surgeons overall, when analyzed individually, right-handed surgeons presented greater acetabular inclination in left hips, suggesting a possible influence of laterality and spatial perception. In contrast, the left-handed surgeon showed no differences by side. The anterior approach was associated with greater acetabular anteversion, especially in right-handed surgeons, with no differences in inclination. Regarding BMI, greater inclination was observed in obese patients, although this varied between surgeons. No significant relationship was found between surgeon dominance and component orientation when comparing the dominant side of right- and left-handed patients. These findings underscore the importance of considering laterality, approach, and BMI in THA surgical planning. Additional studies with larger sample sizes and clinical followup are needed to evaluate their impact on postoperative complications such as dislocation.
