Fetal skull fracture has been reported in conjunction with difficult delivery or extrinsic trauma.
We report a case of linear, undisplaced, nondepressed skull fracture occurring in a 3540-g male infant born at 37 weeks and 4 days' gestation. Linear skull fracture occurred despite an uncomplicated spontaneous vaginal delivery in the absence of extrinsic trauma or cephalopelvic disproportion. Subsequent clinical follow-up 6 years later revealed normal neurological development without evidence of epileptiform activity or focal neurologic deficit.
Linear skull fracture in association with uncomplicated, spontaneous vaginal delivery is distinctly rare, in contrast to focal, congenital molding depressions of the skull. This case demonstrates that normal spontaneous vaginal delivery without instrumentation or obvious complication can involve sufficient trauma to result in a linear skull fracture. The precise etiology of these fractures requires further study.
据报道，胎儿颅骨骨折与难产或外部创伤有关。
我们报告一例线性、无移位、非凹陷性颅骨骨折，发生在一名孕37周4天出生的3540克男婴身上。尽管是无并发症的自然阴道分娩，且无外部创伤或头盆不称，但仍发生了线性颅骨骨折。6年后的后续临床随访显示神经发育正常，无癫痫样活动或局灶性神经功能缺损的证据。
与颅骨局灶性先天性塑形凹陷不同，与无并发症的自然阴道分娩相关的线性颅骨骨折极为罕见。本病例表明，无器械辅助或明显并发症的正常自然阴道分娩也可能涉及足够的创伤，导致线性颅骨骨折。这些骨折的确切病因需要进一步研究。
