Implant retention and removal after internal fixation of the symphysis pubis

Although internal fixation of diastasis of the symphysis pubis is commonly performed, there are no clear guidelines regarding the indications for removal of these implants. The long-term physiologic effects of retaining these internal fixation devices are not well described. We surveyed the literature to assess the current thinking and recommendations regarding implant retention and removal. Twenty-four case series and two case reports were found, for a total of 482 cases. Complications arose as a result of implant retention in 7.5% of patients, with infection the most common complication. There is no consensus in the literature regarding implant retention and removal after internal fixation of diastasis of the symphysis pubis.
