Spondylolysis and absence of the pedicle are congenital anomalies of the posterior cervical spine. Their roentgenographic changes may be confused with other more serious entities which may necessitate either emergent therapy or require extensive diagnostic testing and treatment. Four cases are present and the literature is reviewed. A hypothesis for the embryologic etiology of these entities is proposed.
椎弓崩裂和椎弓根缺如是颈椎后部的先天性异常。它们的X线表现可能与其他更严重的情况相混淆，这些情况可能需要紧急治疗，或者需要进行广泛的诊断检查和治疗。本文报告4例并复习相关文献。提出了这些病变胚胎学病因的假说。
