Carpal Joint Malalignment With Distal Radius Malunion and Factors in Correction After Distal Radius Osteotomy

PurposeThere is a paucity of data regarding recommendations on when to correct for distal radius malunions and if the initial severity radiographic outcomes correlated with ability baseline. We evaluated effects corrective osteotomy preoperative carpal joint malalignment resulting from malunions, injury timing outcomes, developed straightforward classification system predicting radiocarpal midcarpal maladaptive patterns.MethodsA retrospective review included 26 patients (27 wrists) who reported closed treatment fracture subsequently underwent malunion. Data patient demographics, range motion, deformity, deformity correction, postoperative measurements alignment patterns.ResultsOf 27 dorsally angulated 16 were classified as type 1 adaptation 11 2 adaptation. The group showed significant improvements in parameters after surgery, except ulnar variance. parameters, radiolunate angle, radioscaphoid capitolunate angle. exhibited an overall decrease motion compared that group. Severity time taken radius, especially beyond 40 weeks.ConclusionsThe correlate radius. Early correction recommended, patterns. A useful analysis patterns direct measurement articular surface lunate, termed relative-radiolunate angle.Type study/level evidenceTherapeutic IV. There Of weeks.
