Abstract

Three-dimensional analysis of bones, especially for preoperative planning of corrective osteotomy in fracture malunion, assumes that the bilateral extremities exhibit a symmetrical mirror image when projected onto each other. No studies are available for phalanges. Three-dimensional bone models of all phalanges of 20 healthy participants (40 hands) were created from computed tomography data. For each phalanx, the difference between the left and right sides were assessed with respect to axis of rotation, ulnoradial deviation, flexion-extension and bone length.

The average absolute side difference was small, but with significant differences of extension-flexion (mean 1.1°), supination-pronation (mean 1.8°), ulnoradial deviation (mean 0.9°) and translation (mean 0.2 mm). All left proximal phalanges were significantly pronated in comparison to the right side. The differences are likely unimportant, especially in corrective osteotomy using advanced 3D techniques.

基于计算机层析成像的双侧指骨差异三维分析。

骨骼的三维分析，特别是在骨折不愈合的矫正截骨术前计划时，假设双侧肢体在相互投射时呈现对称镜像。没有关于指骨的研究。利用计算机断层扫描数据建立了20名健康参与者（40只手）所有指骨的三维骨模型。对于每个指骨，评估左右两侧之间的差异，包括旋转轴、尺骨偏差、屈伸和骨长度。平均绝对侧差很小，但伸屈（平均1.1°）、旋前（平均1.8°）、尺桡侧偏（平均0.9°）和平行（平均0.2 mm）差异显著。与右侧相比，所有左侧近端指骨均明显内旋。差异可能并不重要，特别是在使用先进的3D技术进行矫正截骨时。

期刊介绍： As the official publication of the French, Belgian and Swiss Societies for Surgery of the Hand, as well as of the French Society of Rehabilitation of the Hand & Upper Limb, ''Hand Surgery and Rehabilitation'' - formerly named "Chirurgie de la Main" - publishes original articles, literature reviews, technical notes, and clinical cases. It is indexed in the main international databases (including Medline). Initially a platform for French-speaking hand surgeons, the journal will now publish its articles in English to disseminate its author''s scientific findings more widely. The journal also includes a biannual supplement in French, the monograph of the French Society for Surgery of the Hand, where comprehensive reviews in the fields of hand, peripheral nerve and upper limb surgery are presented. Organe officiel de la Société française de chirurgie de la main, de la Société française de Rééducation de la main (SFRM-GEMMSOR), de la Société suisse de chirurgie de la main et du Belgian Hand Group, indexée dans les grandes bases de données internationales (Medline, Embase, Pascal, Scopus), Hand Surgery and Rehabilitation - anciennement titrée Chirurgie de la main - publie des articles originaux, des revues de la littérature, des notes techniques, des cas clinique. Initialement plateforme d''expression francophone de la spécialité, la revue s''oriente désormais vers l''anglais pour devenir une référence scientifique et de formation de la spécialité en France et en Europe. Avec 6 publications en anglais par an, la revue comprend également un supplément biannuel, la monographie du GEM, où sont présentées en français, des mises au point complètes dans les domaines de la chirurgie de la main, des nerfs périphériques et du membre supérieur.
