The most common fractures during vaginal delivery occur in the clavicle, humerus, and femur. Cesarean section reduces the chances of a child having a birth injury. However, in some difficult extractions, long bone fractures may occur. Cesarean section further reduces the incidence of birth injuries, especially in a breech delivery. Maneuvers employed during cesarean section, energetic traction, improper uterine incisions, and contracted uterus may cause these injuries. In the medical literature, there are few articles highlighting the occurrence of long bone fractures during cesarean section. There has been no case reported with a combined bilateral humerus and femur fracture in the medical literature.
A 2-day-old neonate born after cesarean section for breech presentation in a twin pregnancy presented with restricted movements of both his arms and right leg. Infantogram revealed bilateral humerus and right femur fracture. Biochemical tests were normal, and there were no other findings on clinical examination. There was no evidence of child abuse or any positive family history. Child was splinted for 3 weeks. X-rays suggested good callus at the fracture site of the right femur and bilateral humerus fracture were united.
To conclude, we would like to emphasize that long bone fractures can happen with cesarean section also. To prevent such untoward complications, during delivery of the baby the surgeon should be very careful, avoid energetic traction and should plan his incisions. Appropriate relaxation of the uterus must be achieved. Clavicles and other long bones should be palpated after a difficult delivery. However, it is important to note that long bone fractures in children heal rapidly without the need for any major intervention.
阴道分娩时最常见的骨折发生在锁骨、肱骨和股骨。剖宫产可降低儿童发生产伤的几率。然而,在一些困难的分娩过程中,可能会发生长骨骨折。剖宫产进一步降低了产伤的发生率,尤其是在臀位分娩时。剖宫产过程中采用的操作、强力牵引、不当的子宫切口以及子宫收缩可能导致这些损伤。在医学文献中,很少有文章强调剖宫产时发生长骨骨折的情况。医学文献中尚未报道过合并双侧肱骨和股骨骨折的病例。
一名2日龄新生儿,因双胎妊娠臀位行剖宫产出生,出现双侧手臂和右腿活动受限。婴儿X线片显示双侧肱骨和右侧股骨骨折。生化检查正常,临床检查无其他异常发现。没有虐待儿童的证据或任何阳性家族史。患儿用夹板固定3周。X线片显示右股骨骨折部位有良好的骨痂形成,双侧肱骨骨折已愈合。
总之,我们想强调剖宫产时也可能发生长骨骨折。为防止此类不良并发症,在分娩婴儿时外科医生应非常小心,避免强力牵引,并应规划好切口。必须使子宫适当松弛。在困难分娩后应触诊锁骨和其他长骨。然而,需要注意的是,儿童长骨骨折愈合迅速,无需任何重大干预。
