To describe the CT findings in occipital condyle fractures in patients suffering craniocervical trauma.
Six occipital condyle fractures in five patients were analyzed. Because of clinical or plain-film findings, the craniocervical junction in each patient was imaged using thin-section, high-resolution CT. Axial data were reformatted in the coronal plane or in both coronal and sagittal planes. Clinical and radiologic findings associated with occipital condyle fractures reported in the English medical literature were correlated with our cases to determine conclusive predictive features indicating condylar injury.
Two avulsion (type III) fractures in two patients, two compression (type I) fractures in one patient, and two compression fractures in two patients were diagnosed by CT. Specific predictive features indicating occipital condyle fracture could not be confirmed.
CT greatly facilitates diagnosing and typing of occipital condyle fractures. Nonspecific parameters promoting CT after trauma are unexplained persistent upper-neck pain with normal plain-film findings, lower cranial nerve palsies, spasmodic torticollis, retropharyngeal or prevertebral soft-tissue swelling, and fractures of the atlas or axis.
描述颅颈创伤患者枕髁骨折的CT表现。
分析了5例患者的6处枕髁骨折。由于临床或平片检查结果，对每位患者的颅颈交界区进行了薄层、高分辨率CT成像。轴向数据在冠状面或冠状面和矢状面进行了重新格式化。将英文医学文献中报道的与枕髁骨折相关的临床和放射学表现与我们的病例进行关联，以确定表明髁突损伤的确切预测特征。
CT诊断出2例患者的2处撕脱性（III型）骨折、1例患者的2处压缩性（I型）骨折以及2例患者的2处压缩性骨折。无法确定表明枕髁骨折的确切预测特征。
CT极大地有助于枕髁骨折的诊断和分型。创伤后促使进行CT检查的非特异性参数包括平片检查结果正常但原因不明的持续性上颈部疼痛、下颅神经麻痹、痉挛性斜颈、咽后或椎体前软组织肿胀以及寰椎或枢椎骨折。
