Misdiagnosis of Suture Anchor Prolapse at the Distal Phalanx of the Little Finger and MRI confirmations: A case report and literature review

Abstract Background Suture anchors have gained widespread use in medical practice due to their numerous benefits. However, they are also linked with specific complications, including prolapse. In this article, we present a case report of suture anchor prolapse occurring at the base of the distal phalanx of the little finger. Case Presentation The patient complained of stiffness and pain upon physical examination. X-ray imaging revealed a high probability of either distal phalanx fracture or tendon adhesion. However, given the lack of a definitive diagnosis, magnetic resonance imaging (MRI) was performed, which indicated bone connectivity between the middle and distal phalanges with patchy high signal shadow, unclear boundaries, and a regular finger shape. Consequently, MRI is considered a superior diagnostic modality for avoiding the misdiagnosis of prolapsed suture anchors. Accurate and timely diagnosis is crucial for effective management of these conditions, and the use of MRI may aid in facilitating prompt and appropriate treatment. Conclusion To the best of our knowledge, this is the first reported case of its kind. Surgical intervention was subsequently performed, which confirmed the findings of the MRI.
