Advanced prenatal ultrasonography techniques have allowed for better understanding of the natural history, treatment, and prognosis of sacrococcygeal teratomas. Several intrauterine surgical techniques to debulk the tumor when fetal and maternal life are in jeopardy have been described. Orthopaedic impairment, such as lower extremity weakness and swelling, also has been described in association with sacrococcygeal teratomas. The authors report on a newborn in whom a large soft tissue defect overlying the posterior hip region with direct exposure of the disarticulated hip joint existed at the time of birth, which resulted from intrauterine radiofrequency ablation of a sacrococcygeal teratoma. This unexpected complication has resulted in a loss of sciatic nerve function, malformation of the acetabulum and femoral head, and loss of the left ischium, coccyx, inferior sacrum, gluteal, adductor and piriformis muscles, and posterior hip capsule. At 16 months of age, the patient has a flaccid left lower extremity with a hypoplastic hip joint.
先进的产前超声检查技术有助于更好地了解骶尾部畸胎瘤的自然病史、治疗方法和预后。已经描述了几种在胎儿和母亲生命受到威胁时用于切除肿瘤的宫内手术技术。与骶尾部畸胎瘤相关的骨科损伤，如下肢无力和肿胀，也已被描述。作者报告了一名新生儿，出生时后髋部区域存在一个大的软组织缺损，髋关节脱位直接暴露，这是由于宫内射频消融骶尾部畸胎瘤所致。这种意外的并发症导致坐骨神经功能丧失、髋臼和股骨头畸形，以及左坐骨、尾骨、骶骨下部、臀肌、内收肌和梨状肌以及后髋关节囊缺失。在16个月大时，该患者左下肢松弛，髋关节发育不全。
