ABSTRACT
Between April 1999 and February 2000, femoral component rotation and asymmetry (universal versus anatomic) were studied in a prospective randomized control trial in 101 consecutive patients undergoing total knee replacement. Patients were randomly assigned to four groups. The same surgical technique was used in all patients except for femoral component symmetry and rotational alignment. Universal femoral components provide a cheaper and equally reliable solution compared to anatomic compo nents. External rotation of the femoral component or using an anatomic femoral component did not statistically reduce the need for lateral release or improve patellar tracking.

El presente reporte presenta dos pacientes atendidos en el Servicio de Columna del Hospital de Traumatología "Dr. Victorio de la Fuente Narváez"del Instituto Mexicano del Seguro Social en 1997 con lesión penetrante de columna vertebral por proyectil de arma de fuego sin lesión neurológica permanente. Un caso neurológicamente íntegro sin tratamiento quirúrgico y el otro caso con compresión radicular de L3 derecha, que mejora después de la extracción del proyectil. Ninguno de los pacientes presentó complicaciones y fueron valorados por 3-6 meses posteriores a la lesión.
