First Carpometacarpal Joint Dislocation and Review of Literatures

Abstract

<br/><span style="font-size: xx-small;">Dislocation of the first carpometacarpal (CMC) is a rare occurrence. Treatment of this dislocation varies from closed reduction and casting to ligament repair. Neglected dislocation or incomplete reduction of the 1</span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">st </span></span><span style="font-size: xx-small;">CMC cause chronic instability and painful arthritis, muscle imbalance and decreased grip force. </span><br/>In our study 6 patients is evaluated that were visited in less than 24 hours from their injury. All were primarily reduced and except one patient later injured ligament were repaired. All patient after 6 months had normal range of motion without pain and they had not any complaint. <br/><span style="font-size: xx-small;">Stability at the 1</span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">st </span></span><span style="font-size: xx-small;">CMC joint is dependent on static and dynamic forces. However, dislocation of the 1</span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">st </span></span><span style="font-size: xx-small;">CMC occur rare, but important function of the thumb specially in gripping and grasping makes it a significant problem. Injured ligament should repair for increased stability of 1</span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">st </span></span><span style="font-size: xx-small;">CMC joint, because neglected dislocation or incomplete reduction cause chronic instability and painful arthritis. </span>
