Abstract

Objective

The purpose of this study was to evaluate the clinical and radiologic outcomes of the first patients who received a dual-mobility trapeziometacarpal prosthesis in our centre, for first carpometacarpal joint osteoarthritis, with a minimum 5-year follow-up.

Patients and methods

Fifty-seven patients received a total trapeziometacarpal ball-and-socket arthroplasty with the Touch® prosthesis for severe arthritis and one for significant laxity. Four patients underwent bilateral surgery. One was lost of follow-up and three died during the study. Function was assessed before surgery and at one, 3, 5 and 10-years follow-up visits. Visual analog scale for pain, active thumb range of motion, including Kapandji’s score, key-pinch grip strength and patients’ satisfaction outcomes were recorded by an independent observer. Standardized radiographs were obtained to assess osteolysis, loosening, and subsidence.

Results

Patients were followed for an average of 6.5 years (5–8.8). Pain decreased from 7.3 to 0.4, range of motion increased, and key grip strength improved from 67% to 102% of the contralateral side. Metacarpophalangeal hyperextension was present in 26 thumbs (46%) before surgery (5 severe, more than 30°), and in 19 thumbs (33%) at follow-up. Z-deformity was reported in 13 cases (23%) preoperatively and in 2 cases (4%) postoperatively. At maximum follow-up, radiographs showed minor osteolysis in 4 cases (7%) around the trapezium component and in 7 cases (12%) around the metacarpal component. One revision (2%) was required for cup loosening 7 years after surgery. All patients were satisfied or very satisfied with the treatment.

Conclusions

This prospective study of 61 Touch® dual mobility prostheses confirms that this implant is a safe and effective treatment option for trapeziometacarpal osteoarthritis in the short and medium term. Continued follow-up is necessary to assess the long-term outcomes of this arthroplasty.

Level of evidence

61例Touch®梯形腕关节假体的5 -8年前瞻性随访。

目的：本研究的目的是通过至少5年的随访，评估在我们中心首次接受双活动的腕关节骨关节炎患者的临床和影像学结果。患者和方法：57例重度关节炎患者接受Touch®假体全斜跖骨球窝置换术，1例明显松弛患者接受Touch®假体置换术。4例患者接受了双侧手术。1人失去随访，3人在研究期间死亡。术前及1年、3年、5年和10年随访时评估功能。由独立观察员记录疼痛视觉模拟量表、拇指活动范围（包括Kapandji评分）、键捏握力和患者满意度。获得标准化x线片以评估骨溶解、松动和下沉。结果：患者平均随访6.5年（5 ~ 8.8年）。疼痛从7.3下降到0.4，活动范围增加，对侧关键握力从67%提高到102%。在手术前26个拇指（46%）出现掌指关节过伸（5个严重，超过30°），随访时19个拇指（33%）出现掌指关节过伸。术前z型畸形13例（23%），术后2例（4%）。在最大随访时，x线片显示4例（7%）在斜方周围有轻度骨溶解，7例（12%）在掌骨周围有轻度骨溶解。术后7年因杯杯松动需要进行一次翻修（2%）。所有患者均对治疗满意或非常满意。结论：这项对61个Touch®双活动假体的前瞻性研究证实，该假体在中短期内是一种安全有效的治疗斜跖骨关节炎的选择。需要继续随访以评估该关节置换术的长期效果。证据水平：II。

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.
