Necrosis avascular secundaria al tratamiento de la luxaci贸n cong茅nita de cadera: relaci贸n entre factores terap茅uticos y secuelas radiol贸gicas
Se presentan 108 casos de Luxaci贸n Cong茅nita de Cadera (LCC) unilateral tratados
con la misma met贸dica terap茅utica: tracci贸n m谩s reducci贸n abierta o cerrada dependiendo
de los hallazgos artrogr谩ficos. Tras un seguimiento medio de 7 a帽os (Rango: 5-13),
5 (5%) ten铆an una coxa magna, 14 (13%) mostraban disminuci贸n de la altura epifisaria, 22
(20%) ten铆an una coxa magna con disminuci贸n de la altura epifisaria 10 (9%) presentaban
lesi贸n fisaria residual. El an谩lisis estad铆stico demostr贸 asociaci贸n significativa (p<0,05 ) entre
el desarrollo de coxa magna con disminuci贸n de la altura epifisaria y la ausencia de descenso
cef谩lico al terminar la tracci贸n, as铆 como con la reducci贸n abierta. La lesi贸n fisaria residual,
se encontr贸 asociada significativamente a LCC Tipo IV de T枚nnis, caderas que estuvieron m谩s
de 5 semanas en tracci贸n, fallo en el descenso cef谩lico al finalizar la tracci贸n y reducci贸n abierta.
En conclusi贸n, se recomienda la tracci贸n preoperatoria 芦efectiva禄, que desciende la cabeza
femoral a nivel del cotilo, para disminuir las alteraciones radiol贸gicas finales, secuelas de necrosis
avascular.A total of 108 patients with unilateral congenital dislocation of the hip treated
by the same therapeutic approach, are reviewed. The protocol for treatment consisted in traction
and open or closed reduction, depending of the arthrographic findings. After 7-year follow-up
(range, 5-13), 5 (5%) had coxa magna, 14 (13%) showed a decrease in epiphyseal height, 22
(20%) exhibited both coxa magna and decreased epiphyseal height, and 10 (9%) showed physeal
damage. The statistical analysis revealed a significant relationship (p < 0,05) between the development
of coxa magna with decreased epiphyseal height and both an absence of femoral head
descent after traction and an open reduction of the hip. Physeal damage was found to be associated
to T枚nnis type-IV congenital dislocation, to hips undergoing more than 5 weeks traction, to
failed cephalic descent following traction and an open reduction procedure. In conclusion, a
effective preoperative hip traction allowing an appropriate descent of the femoral head to the
acetabulum is recommended in order to prevent radiological alterations induced by avascular
necrosis
