Sexual activity, pregnancy, and childbirth after periacetabular osteotomy.

The purpose of the current study was to determine the effect periacetabular osteotomy has on sexual activity, pregnancy, and childbirth. Eighty-eight female patients who had periacetabular osteotomy were asked to complete a questionnaire concerning the presence of hip pain and changes in the frequency, positions, and satisfaction of sexual activity after periacetabular osteotomy. They also were asked about hip pain during pregnancy and after childbirth, type of delivery, and complications during childbirth. Eighty-four patients (89%) either were very satisfied or satisfied with the surgery. Thirty-eight (40%), 44 (46%), and 24 (25%) patients reported changes in the frequency, positions, and satisfaction of sexual intercourse, respectively. Sixteen women had 24 pregnancies. Fifteen women had vaginal deliveries and eight had Cesarean sections. Less than 5-mm medialization of hip center after correction was associated with pain (in seven of seven patients) and decreased range of motion (in eight of nine patients) during sexual activity. Acetabular retroversion was found in 16 patients postoperatively, and 15 of them had hip pain after periacetabular osteotomy. None of the patients who reported an increased frequency of sexual intercourse had retroversion. The majority will be able to deliver a child vaginally.
