Comparative Study of Dorsal and Volar Plating for Ulnar Shortening Osteotomy.
JOURNAL OF HAND SURGERY-ASIAN-PACIFIC VOLUME(2020)
摘要
Background: Postoperative results of ulnar shortening osteotomy for ulnar abutment syndrome were compared between groups of patients in whom the plate was placed on the volar side and those in whom the plate was placed on the dorsal side. Methods: A total of 35 wrists of 14 males and 21 females were evaluated. The average age of patients at surgery was 44.3 years, and the average follow-up period was 66.2 months. After transverse osteotomy was performed, the ulna was fixed using a 6-hole LC-LCP or a LC-DCP on the dorsal (group D) or the volar (group V) side, respectively. Imaging and clinical results, rates and reasons for implant removal were evaluated. Results: There were 27 patients in group D and 8 in group V. A significant difference was observed only in the postoperative grip strength compared with that of the unaffected side between groups V and D (102% and 87%, respectively). Implant removal was performed in 18 (64%) patients in group D and in 7 (88%) in group V, and the main reasons for this were pain in group V and discomfort in group D. Re-fracture occurred after implant removal in one patient in group D. Conclusions: There were no differences in the imaging and clinical results depending on the plate position. It is preferable to avoid implant removal by placing the lower profile plate on the dorsal side.
