摘要

本研究探讨了背侧韧带修复加内支架增强是否比单纯的背侧韧带修复更能立即稳定梯形掌关节。研究使用了七对匹配的尸体手掌。每对尸体中的一个标本被分配到单纯修复组,另一个标本被分配到修复+内支架加固组。两组在不同条件下对肘掌关节的活动范围和平移进行了量化:1)完整组;2)背侧韧带横断组;3)修复背侧韧带组或修复背侧韧带加内支架增强组。修复后进行了载荷-失效测试。背韧带横断增加了活动范围和平移幅度,而背韧带修复则减少了活动范围和平移幅度;不过,与完好的情况相比,仅修复组的屈伸幅度更大,而修复+内支架组的活动范围没有明显差异。与单纯修复组相比,修复+内部支撑组在2毫米和3毫米位移时的平均载荷更大(2毫米位移时分别为18.0 ± 1.8 N vs 10.8 ± 1.3 N,3毫米位移时分别为35.3 ± 3.7 N vs 23.1 ± 2.9 N)。内支架加固改善了背侧韧带修复的负载-失效特性,同时不影响活动范围。证据等级:四级。

Internal brace augmentation improves the biomechanical properties of trapeziometacarpal joint dorsoradial ligament repair

This study investigated whether dorsoradial ligament repair with internal brace augmentation provided more immediate stability in the trapeziometacarpal joint than dorsoradial ligament repair alone. Seven matched pairs of cadaveric hands were used. One specimen from each pair was assigned to the repair-only group and the other to the repair + internal brace augmentation group. Trapeziometacarpal joint range of motion and translation were quantified under different conditions for both groups: (1) intact, (2) transected dorsoradial ligament, and (3) repaired dorsoradial ligament or repaired dorsoradial ligament plus internal brace augmentation. Load-to-failure tests were performed after repair. Range of motion and translation were increased by dorsoradial ligament transection and were decreased by dorsoradial ligament repair; however, compared to the intact condition, the repair-only group demonstrated greater flexion/extension range, while the repair + internal brace group showed no significant difference in range of motion. Mean loads at 2- and 3-mm displacements were greater in the repair + internal brace group than in the repair-only group (18.0 ± 1.8 N vs. 10.8 ± 1.3 N for 2 mm displacement and 35.3 ± 3.7 N vs. 23.1 ± 2.9 N for 3 mm displacement, respectively). Internal brace augmentation improved the load-to-failure characteristics of dorsoradial ligament repair without compromising range of motion.

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.
