Demographic and surgical factors were abstracted. Preoperative, immediate postoperative, and final follow-up scapholunate (SL) angles were measured. Radiographic union (>75% healing) and patient-reported pain at final follow-up were assessed. Associations between SL angle measurements, patient characteristics, and surgical variables with union and pain were evaluated using unpaired\n t<\/jats:italic>\n tests and \u03c7\n 2<\/jats:sup>\n tests.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Fifty-five patients met inclusion criteria with persistent nonunion occurring in 17 patients (30.1%). Patient sex was significantly associated with union (\n P<\/jats:italic>\n = .045) but not pain at final follow-up (\n P<\/jats:italic>\n = .399). All other demographic factors (smoking status, diabetes, prior surgery) and surgical factors (fracture location, surgical approach, implant type, graft type, and use of adjunct Kirschner-wire) were not significantly associated with union or pain at final follow-up (all\n P<\/jats:italic>\n > .05). Among SL angle measurements, only a lower final follow-up SL angle was significantly associated with higher union rates (\n P<\/jats:italic>\n = .038). No SL angle measurement was associated with pain at follow-up (all\n P<\/jats:italic>\n > .05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Patient sex was associated with union. No other demographic or surgical variables were associated with union or pain at final follow-up. A lower SL angle at final follow-up was independently associated with successful union, suggesting that correction of carpal alignment may contribute to improved healing in scaphoid nonunion repair.<\/jats:p>\n
