Age and Migration Percentage as Risk Factors Tor Progression in Spastic Hip Disease

Abstract: SUMMARY Age and migration percentage were evaluated as risk factors for the progression of spastic hip subluxation in patients with cerebral palsy. Three age‐groups were defined: group I (two to eight years), group 2 (nine to 18 years), and group 3 (over 18 years). Four subluxation groups were defined by migration percentage: group A (<30 per cent), group B (30 to 60 per cent), group C (60 to 90 per cent), and group D (>90 per cent). The risk of progression was the same in groups 1A and 2A. and both of these w… Show more

“…We defined a normal hip as having a RMI B30 %, mildly subluxated as 30 % \ RMI \ 60 %, severely subluxated as 60 % B RMI \ 90 %, and dislocated as RMI C90 %. Severely subluxated hips with an unfavorable prognosis based on migration index ([60 %) were considered failures to cure, since we would predict that all of these would become dislocated over the long term [23].…”

“…Miller e Bagg (3) concluíram, em seu estudo, que dois fatores são importantes para bom prognóstico: pacientes deambuladores e pacientes com menor envolvimento motor. Nesse mesmo estudo, os autores referem que a idade na época da cirurgia não influenciava nos resultados, o que vai de acordo com nosso estudo; porém, nossos pacientes não eram deambuladores e eram mais gravemente acometidos.…”

“…Sabemos que a chance de remodelação do acetábulo e a melhora no índice de Reimers são menores quando a cirurgia é realizada após os oito anos, porém o melhor equilíbrio muscular com o tratamento cirúrgico evita a progressão da luxação mesmo em pacientes maduros, e essa não progressão pode ser considerada como bom resultado. Miller e Bagg (3) afirmam que pacientes com índice de Reimers acima de 30% apresentam 23% de progressão mesmo após a maturidade esquelética, o que pode justificar o procedimento em pacientes adultos e com subluxação de quadris.…”
