In this type of injury, which causes serious functional problems in the hand if not treated appropriately, closed methods are generally used in the treatment. In this study, we present a case with fracture-dislocation of the 5th CMC joint. Case: Fracture-dislocation of the 5th CMC joint of a 25-year-old patient who was admitted to the emergency department due to wrist pain was not noticed. The diagnosis was made during the follow-up of the patient, and the joint was reduced with closed method and fixed with a K wire. No serious problems were encountered in the patient's controls.Conclusion: Undiagnosed 5th CMC joint dislocation disrupts the transverse and longitudinal arches of the hand, so the patient has a weak and painful gripping function. Radiological findings may be unclear on anterior-posterior and lateral views, and additional images may be obtained if in doubt.
