Orthopedic issues in pregnancy.

Pregnancy taxes the musculoskeletal system. The enlarging gravid uterus alters the maternal body's center of gravity, mechanically stressing the axial and pelvic systems, and compounds the stresses that hormone level fluctuations and fluid retention exert. While the pregnant woman is prone to many musculoskeletal injuries, most can be controlled conservatively, but some require emergent surgical intervention. This article describes pregnancy-related orthopedic problems and related conditions, and discusses their pathogenesis, signs, symptoms, physical examination findings, diagnostic work-up, and interventions. Topics specifically covered include the following: pregnancy-related posterior pelvic pain (PRPPP), lumbar disc herniation with cauda equine syndrome, low back pain, kyphoscoliosis and scoliosis issues for anesthesia during pregnancy and delivery, pubic symphysis rupture, transient osteoporosis versus osteonecrosis, management of pregnancy after hip replacement surgery, and carpal tunnel syndrome. Specific musculoskeletal systems discussed in this article include the spine, pelvis, hip joint, and wrist.
