Case: A 29-year-old woman presented with spontaneous, isolated, total palmar scaphoid subluxation in the left hand approximately 6 weeks postpartum. She had a positive Watson scaphoid shift test, with an easily subluxable and reducible scaphoid unilaterally. She was diagnosed with scapholunate ligamentous laxity with dynamic instability. Approximately 4 months after stopping lactation, she had complete resolution of the scapholunate subluxation; there was no recurrence of symptoms over the next 5 years of follow-up. Conclusion: Women can havemanifestations of pregnancy and lactation-related ligamentous laxity, including scapholunate instability, which may spontaneously resolve upon cessation of lactation.
