Revision surgery after pregnancy in a patient with congenital kyphoscoliosis

Abstract

Rationale:Rod breakage during pregnancy and delivery has never been described in a patient who has undergone surgery for congenital scoliosis (CS). Here, we present an unusual but significant case of revision surgery.Patient concerns:A 29-year-old woman presented with low back pain during pregnancy after posterior osteotomy, correction and fusion at T9 to L5 for CS. Radiographs during follow-up, 4 months after the patient gave birth, demonstrated rod breakage.Diagnoses:Rod breakage after orthopaedic surgery of congenital kyphoscoliosisInterventions:The patient was taken into the operating room for replacement of the broken rods, recovery of sagittal balance, bone graft fusion, and improvement of stability by cross-connection. The patient recovered fully by the 3-month postoperative follow-up.Outcomes:In follow-up, the instruments were in good condition, the orthopedic effect was not lost, and low back pain relief was observed.Lessons:We opine that the rod breakage during pregnancy resulted from weight gain and a lack of an anterior approach to the supportive bone graft. Therefore, female patients with spinal surgery should visit the hospital for advice before pregnancy.

Unusual cause of hemoptysis: A case report

“…The physical burden that a fetus places on the spine of the mother with underlying scoliosis might lead to curve progression and – as a consequence - rod migration [ 17 ]. Li et al [ 19 ] described a case of revision surgery after pregnancy (4 months after the patient gave birth) in a patient with congenital kyphoscoliosis, in who the spinal rod was broken. The authors reported that the weight gain of pregnancy was the most likely reason for the rod breakage.…”
