| The fracture extends to the carpometacarpal joint and the displacement is made worse and more unstable by the abductor muscles of the first metacarpal. |
| These involved, in addition to the base of the first carpometacarpal joint, the trapezium, navicular, surrounding fascial structures or the abductor pollicis brevis muscle. |
| An example of a sellar joint is the carpometacarpal joint of the thumb. |
| What are we supposed to believe about the sketchy information coming out about the injuriness of Peyton Manning's carpometacarpal joint? |
| The carpometacarpal portion of the articulation is the part which is usually affected. |
| Sometimes the fracture occurs at the base and the carpometacarpal joint, and there is the possibility of an associated dislocation or subluxation of the joint. |
