PURPOSE: In this study, we designed a prospective project to test the hypothesis that acute fourth and fifth carpometacarpal (CMC) @entity174 can be treated conservatively with good restoration of strength, range of motion (ROM), and function, whereas @entity1 with delayed treatment of fourth and fifth @entity174 should be treated with open reduction and internal fixation (ORIF). METHODS: We evaluated the results of 20 @entity1 with acute and 6 @entity1 with subacute fourth and fifth @entity174 . All 20 @entity174 were treated conservatively, whereas 3 of the 6 @entity1 with subacute injuries underwent operative intervention. The sensibility, ROM, and grip strength of the hands were tested during 1-year follow-up. The Michigan Hand Outcomes Questionnaire and control radiographs were also taken. RESULTS: All 20 @entity1 with @entity174 showed good restoration of grip strength, ROM, and function, with an average Michigan Hand Outcomes Questionnaire score of 98    2 at 1-year follow-up. @entity1 with delayed diagnosis who underwent conservative treatment had noticeable deformity of their injured hands, @entity158 complaints, limited ROM at the fourth and fifth @entity2720 , and decreased grip strength. The 3 @entity1 with delayed diagnosis treated with ORIF showed good restoration of grip strength, ROM, and function. CONCLUSIONS: @entity1 with @entity174 can be treated by closed reduction with good restoration of grip strength, ROM, and function. In @entity1 with delayed presentation of @entity174 , we recommend ORIF. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
