A viable alternative to using vascularized bone grafts for scaphoid nonunions with AVN is nonvascularized bone grafting with screw fixation.<\/jats:p><jats:p>\n          Question\u2003What are the functional outcomes of patients with scaphoid nonunions and associated proximal pole AVN who are treated with nonvascularized distal radius bone grafting and screw fixation?<\/jats:p><jats:p>\n          Patients and Methods\u2003Eight scaphoid nonunions with AVN, which received nonvascularized distal radius bone graft and screw fixation, underwent a retrospective review. Range of motion, strength, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores were obtained. Follow-up X-rays were compared with immediate postoperative X-rays.<\/jats:p><jats:p>\n          Results\u2003At a mean follow-up of 88.9 months, thumb palmar abduction and radial abduction were significantly higher on the operative side (p\u2009=\u20090.28 and 0.49, respectively). Extension\/flexion arc was significantly lower in the operative wrist (p\u2009=\u20090.148). There was no significant difference between the operative and nonoperative sides with regard to strength. The median postoperative DASH score was 2.9 (interquartile range [IQR]: 8.3). There was no progression of osteoarthritis when immediate postoperative and follow-up X-rays were compared. Radiographic union was observed in six of the seven (85.7%) patients who were able to return to the office for follow-up radiographs. The mean scapholunate and radioscaphoid angles measured on X-rays were within normal anatomic range postoperatively.<\/jats:p><jats:p>\n          Conclusions\u2003Using nonvascularized distal radius bone graft and screw fixation in the treatment of scaphoid nonunions with associated AVN has favorable radiologic and functional outcomes and should be considered a viable treatment option for this difficult problem.<\/jats:p>","DOI":"10.1055\/s-0043-1768236","type":"journal-article","created":{"date-parts":[[2023,4,12]],"date-time":"2023-04-12T23:00:31Z","timestamp":1681340431000},"page":"024-030","source":"Crossref","is-referenced-by-count":7,"title":["Scaphoid Nonunions Treated with Nonvascularized Bone Grafting and Screw Fixation"],"prefix":"10.1055","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0825-4684","authenticated-orcid":false,"given":"Robert L.","family":"Zondervan","sequence":"additional","affiliation":[{"name":"McLaren Greater Lansing Hospital, Department of Orthopedics, Lansing, Michigan"},{"name":"Sparrow Hospital, Lansing, Department of Orthopedics, Michigan"},{"name":"Michigan State University, College of Osteopathic Medicine, East Lansing, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica R.","family":"Childe","sequence":"additional","affiliation":[{"name":"Tulsa Bone and Joint, Tulsa, Oklahoma"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robin","family":"Kustasz","sequence":"additional","affiliation":[{"name":"McLaren Greater Lansing Hospital, Department of Orthopedics, Lansing, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erich E.","family":"Hornbach","sequence":"additional","affiliation":[{"name":"Sparrow Hospital, Lansing, Department of Orthopedics, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2023,4,12]]},"reference":[{"issue":"11","key":"ref1","first-page":"861","article-title":"Scaphoid fractures and scaphoid nonunion.
