To assess the incidence of vaginal birth -related rupture of the pubic symphysis in Finland from 1998 to 2018.
A retrospective cohort study using nationwide data from the Finnish Care Register for Health Care and the Finnish Medical Birth Register. As participants we included all ≥ 22-week pregnancies of women aged between 15 and 49 years from January 1, 1998 to December 31, 2017. Pubic symphysis rupture was classified based on the ICD-10 code S33.4 and operations were gathered with pelvis-specific operation codes of the Nordic NOMESCO-classification. Incidence per 100 000 deliveries with 95% confidence intervals (CI) was calculated for symphysis rupture and surgery using Poisson's exact test.
For a total 1 175 326 deliveries, a total of 9 pubic symphysis ruptures occurred during the intrapartum and puerperal periods. All ruptures occurred after vaginal delivery. Of these, 4 ruptures were treated operatively. The incidence of rupture for vaginal delivery was 0.9 per 100 000 deliveries (CI 0.1 to 1.0). No perinatal mortality was observed.
Birth -related ruptures of the pubic symphysis are rate events and are mostly associated with vaginal delivery with most ruptures being treated conservatively.
评估 1998 年至 2018 年芬兰阴道分娩相关耻骨联合破裂的发生率。
这是一项使用来自芬兰医疗保健注册中心和芬兰医疗出生登记处的全国性数据进行的回顾性队列研究。我们将 1998 年 1 月 1 日至 2017 年 12 月 31 日期间年龄在 15 至 49 岁之间的所有≥22 周妊娠的女性纳入研究。耻骨联合破裂根据 ICD-10 编码 S33.4 进行分类，手术则通过北欧 NOMESCO 分类的骨盆特定手术代码收集。使用泊松精确检验计算耻骨联合破裂和手术的每 100000 次分娩发生率（95%置信区间[CI]）。
在总计 1175326 次分娩中，共有 9 例在分娩期和产褥期发生耻骨联合破裂。所有破裂均发生在阴道分娩后。其中，4 例接受了手术治疗。阴道分娩的破裂发生率为 0.9/100000 次分娩（CI 0.1 至 1.0）。未观察到围产期死亡。
分娩相关的耻骨联合破裂是罕见事件，主要与阴道分娩相关，大多数破裂采用保守治疗。
