Classification and treatment of hand deformities of arthrogryposis multiplex congenita: a clinical analysis

Objective To explore the classification and treatment efficacy of hand deformities of arthrogryposis multiplex congenita. Methods From January 2010 to January 2018, 72 patients (144 thumbs, 556 other fingers) with hand deformities of arthrogryposis multiplex congenita were treated. The patients were divided into 6 groups according to their different pathological and anatomical characteristics and treated accordingly. Results Postoperatively, 60 patients (93 thumbs, 296 other fingers) were follow-up for 1 to 83 months, with an average of 16.2 months. The overall excellent and good rate of the clinical efficacy of the affected fingers was 87.4% (340/389), of which 76.3% (71/93) was for the thumbs and 90.9% (269/296) for the other fingers. All skin grafts survived and 1 finger recurred. Conclusion All the patients in this group have satisfactory finger movement and high safety after treatment. Therefore, according to the classification method described in this paper, the patients with hand deformities of arthrogryposis multiplex congenita can be treated accordingly, which can achieve good results.
