Pubic symphysis diastasis is a complication of pregnancy that can lead to prolonged recovery, persistent pain, and functional disability if managed inappropriately. There is a lack of universally accepted clinical guidelines with regards to the timeframe and defect criteria for surgical management, which contributes to delayed care resulting in increased surgical complexity and subsequent impairments in functionality and quality of life. The current standard of care utilizes non-operative measures exclusively for separations measuring less than 2.5 cm correlating to symphyseal ligament sparing. Surgical interventions are typically reserved for severe cases or those resistant to initial non-operative treatment. Non-surgical methods have been attempted for 4–6 weeks, even in severe cases, with patients still requiring eventual surgery. We herein report an uncommon case of pubic symphysis diastasis measuring 5.5 cm and the successful implementation of non-surgical management to demonstrate the need for updated standardized treatment guidelines. The defect in this case was treated with early application of a pelvic binder resulting in anatomic alignment and full resolution of pain within 3 months, and full return to activity within 6 months. In conclusion, the establishment of management guidelines for pubic symphysis is recommended, including the use of non-surgical management early in the patient recovery process and in cases with diastasis greater than 2.5 cm. This treatment strategy may decrease morbidity, recovery time, and complications in affected patients.
