Fourth and fifth CMC fracture-dislocations are unstable, and dorsal metacarpal dislocations are most common. Operative management for maintaining reduction of the unstable fracture-dislocation was closed reduction and percutaneous pinning; however, in delayed fractures, open reduction is necessary. We report on a plating technique used for acute and delayed, unstable fourth and\/or fifth CMC fracture-dislocations. This method of plating is novel and allows for physiological motion at the CMC joint through a dorsal buttressing mechanism while maintaining joint reduction. The range of motion begins within the first week postoperatively, and full composite fist formation and digital extension occur 4 to 6 weeks postoperatively. This novel technique affords an alternative effective surgical treatment option with excellent outcomes for patients presenting with fourth and fifth CMC fracture-dislocations up to 12 weeks following the injury.<\/jats:p>","DOI":"10.1097\/bth.0000000000000443","type":"journal-article","created":{"date-parts":[[2023,7,11]],"date-time":"2023-07-11T09:00:05Z","timestamp":1689066005000},"page":"239-242","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Treatment of Fourth and Fifth Carpometacarpal Fracture-Dislocations in Punching Injuries With Motion-Sparing Hamate Fixation Spring Plates: \u201cRabbit Ears\u201d Plating"],"prefix":"10.1097","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1578-0989","authenticated-orcid":false,"given":"Shelby R.","family":"Smith","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Rush University Medical Center"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Santucci","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Midwestern University, Downers Grove, IL"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul M.","family":"Lamberti","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, John H.
