Arthrogryposis multiplex congenita: spectrum of upper limb deformities concerning a series of cases

Introduction: Arthrogryposis multiplex comprises a complex group of pathologies that cause decreased joint mobility. Its treatment is focused on improving mobility through physical rehabilitation and surgery in some cases. Objective: To depict upper limb deformities caused by arthrogryposis, as well as the types of treatment and results. Materials and methods: 27 cases (19 operated) were considered for this study, and were grouped according to distal involvement in fingers or wrist or proximal involvement in elbow and shoulder. Results: The most affected areas were wrists and fingers; two cases of only elbow involvement were observed. Surgeries included z-plasties, palmar plate release and joint fixation. Soft tissue release, provisional fixation and arthrodesis were performed on the wrist. There was one case of triceps release, another of pterygium release and another of muscle transfer for elbow flexion. Conclusion: A decrease or absence of folds in flexion areas, as well as internal shoulder rotation, marked limitation of elbow flexion, wrist flexion and ulnar deviation were observed in the upper limbs. Camptodactyly and thumb adduction were found on the fingers. Surgeries improved daily activities function. The treatment is individualized and takes into consideration the degree of affectation
