Purpose: We aimed to report the incidence of peripheral nerve decompression surgery during pregnancy and 12 months after delivery in Finland from 1999 to 2017.

Methods: Using nationwide data from the Finnish Care Register for Health Care and the Finnish Medical Birth Register, all women of potentially childbearing age (15-49 years) who underwent peripheral nerve decompression surgery or had a pregnancy ending in delivery from January 1, 1999, to December 31, 2017, were included. Incidence rates and incidence rate ratios for operations were calculated for both childbearing women and the age-adjusted general female population.

This retrospective cohort study assesses the incidences of major fractures and surgery in women during the puerperium and the lactation period in Finland between January 1, 1999, and December 31, 2018. Using nationwide data from the Finnish Care Register for Health Care and the Finnish Medical Birth Register, all women aged between 15 and 49 years with a fracture hospitalization within 12 months of delivery between 1999 and 2018 were included. During the study period, a total of 3140 fractures after delivery and 152,800 fractures of the female normal population of similar age were hospitalized.

Background: To date, only a few small studies have assessed the effects of major orthopedic traumas on the subsequent birth rate in fertile-aged woman. We assessed the incidences of traumatic brain injury (TBI) and fractures of the spine, pelvis, and hip or thigh and evaluated their association with the birth rate in fertile-aged woman.

Methods: In this retrospective register-based nationwide cohort study, data on all fertile-aged (15-44 years of age) women who sustained a TBI or fracture of the spine, pelvis, hip or thigh between 1998 and 2013 were retrieved from the Care Register for Health Care.
