Osteoporosis transitoria del embarazo: serie de casos

Transient osteoporosis of pregnancy is a pathology of low prevalence and difficult diagnosis that mainly affects pregnant women in the third trimester of pregnancy. It is characterized by mechanical joint pain, more frequent in the lower limbs, radiological osteopenia, and bone oedema on magnetic resonance imaging. A series of 4 cases is presented in pregnant women between 26 weeks of gestation and the early puerperium with symptoms of coxalgia and/or knee pain. The treatment was based on conservative measures: analgesics that are allowed during pregnancy and non-weight bearing on the joints, and the possibility of corticosteroid infiltration into the joint. Bisphosphonates can be added in the puerperium. All cases resolved within a maximum of 9 months, without subsequent sequelae.
