Comparison Of Posterior Correction Results Between Marfan Syndrome Scoliosis And Adolescent Idiopathic Scoliosis

Aims:To analyze whether there are differences of posterior correction surgery in Marfan syndrome scoliosis(MSS)with that of adolescent idiopathic scoliosis(AIS).Methods:All the patients included underwent posterior correction surgery.The radiographic data,operation duration,estamited blood loss,transfusion,fusion levels and correction ratewere analyzed between the 2 groups.Results:Group MSS included 42 patients,11 male and 31 female with an average age of 15.2 years old.Ten patients had a single curve,and 24 patients had 2 curves and the other 8 patients had 3 curves.Group AIS included 168 patients(ratio,1:4),34 male and 134 female with an average age of 14.5 years old.Forty patients had a single curve,and 96 patients had 2 curves and the other 32 patients had 3 curves.Twenty-three patients in group MSS and 94 patients in group AIS followed up,with an average time of 18.4 months and 18.5 months,respectively.The mean coronal Cobb angle of the major curve before operation and at final follow-up,the correction rate,fusion level,operation duration,estimated blood loss(EBL)during operation,transfusion bwtween the 2 groups were 60.4° and 57.5°,14.6° and 15.2°,76.4%and 74.1%,11.5 vertebra and 11.0 vertebra,4.6 hours and 4.0 hours,845ml and 698ml,and 1151ml and 894ml,respectively.The age,gender ratio,curve type and coronal Cobb angle of the major curve were all matched(all P>0.05).Group MSS had a longer operation duration and more EBL compared with those of group AIS(both P<0.05),while there was no significant difference in terms of fusion level,transfusion,coronal Cobb angle of the major curve at final follow-up and correction rate(all P>0.05).Conclusions:When perform scoliosis correction,the patients with Marfan syndrome scoliosis had a more EBL,and longer operation duration than those of AIS patients,while the correction rate was similar.
