Obesity as a moderator of lumber spine posture change during pregnancy.

Background: Low back pain is one of the most common orthopedic issues during pregnancy, sometimes linked to a "gestational lordosis" spine posture. The aims in this study were to explore how the lumbar spine changes, establish the relationship of lumbar curvature to torso anthropometry, and determine if anthropometry can be used to predict lumbar angle changes during pregnancy.

Methods: Anthropometry and comfortable standing spine curvature were measured longitudinally during the last seven months of pregnancy of eleven pregnant participants.

Spontaneous spinal epidural hematoma in pregnancy associated with using low molecular weight heparin.

Background: Spontaneous epidural hematoma of the spine occurring in pregnancy is uncommon and may result in permanent damage if not promptly treated. The use of low molecular weight heparin may be a risk factor for this condition.

Case: We describe the case of a woman who presented at 27 weeks of gestation with progressive back pain and leg weakness while being treated with low molecular weight heparin.
