小儿齿突骨折

Fractures of the Odontoid Process in Children

报道小儿齿突骨折１７例。其中含Ａｎｄｅｒｓｏｎ－Ｄ’ＡｌｏｎｚｏⅡ型骨折１３例，Ⅲ型骨折４例。对于７例新鲜骨折均采用非手术治疗，１０例陈旧性损伤则行枕颈融合术。随访２～１４年，７例行非手术治疗者均达到骨性愈合，１０例行手术治疗者有９例植骨获得骨性愈合，疗效满意。提出新鲜骨折应以非手术治疗为主，而对陈旧性损伤伴寰枢椎不稳者则应行融合手术。

Seventeen cases of odontoid fractures in children were reported.There were 13 Anderson and D'Alonzo Type Ⅱ and 4 Type Ⅲ fractures.For all the acute fractures,conservative therapy was instituted.Ten chronic cases had atlanto occipital arthrodesis.The patients were followed up for 2-14 years.All of 7 cases treated conservatively and 9 of 10 cases undergoing fusion achieved bony union.The results were satisfactory.Conservative therapy is suggested for the acute injury while atlanto occipital fusion should be indicated when atlanto axial instability induced by chronic injuries.
