[Case of bilateral obturator neuropathy after caesarean section].

We describe a case of bilateral obturator neuropathy after caesarean section. A 33-year-old woman expecting her first baby had rotational acetabular osteotomy 8 and 9 years ago. After the surgery, she complained of weakness in the lower limbs and diagnosed as bilateral obturator neuropathy by orthopedist. Rotational acetabular osteotomy is known as one of the causes of narrow mid-pelvis diameter and it raises probability of caesarean section. Contracted pelvis may cause obturator neuropathy after delivery and we need to exclude complications by epidural blockade.
