TY - JOUR T1 - Hand Deformity in Parkinson’s Disease: A Case of Striatal Hand Deformity Mimicking Rheumatoid Arthritis AU - Tunçekin, İsmail AU - Toprak, Murat AU - Kaya, Ümit PY - 2025 DA - August JF - Kafkas Journal of Medical Sciences JO - KAFKAS TIP BİL DERG PB - Kafkas Üniversitesi WT - DergiPark SN - 2146-2631 SP - 270 EP - 272 VL - 15 IS - 2 LA - en AB - Abnormal postures and deformities can be seen in the hands and feet in parkinson’s disease. The most typical deformities seen in the upper extremities are flexion of the metacarpophalangeal joints, extension of the proximal interphalangeal joints, flexion of the distal interphalangeal joints, and ulnar deviation. These deformities may cause rheumatoid arthritis to be misdiagnosed and unnecessary medical treatment given to patients whose Parkinson’s findings, such as tremor, bradykinesia, and rigidity, are not fully established. In our case, there was a male patient with hand deformities in his right upper extremity due to Parkinson’s disease, and his differential diagnosis was made with rheumatoid arthritis. It was aimed to prevent the progression of deformities by starting physical therapy after the diagnosis was made. This case shows that there may be a diagnosis confusion due to the similar hand deformities in rheumatoid arthritis and Parkinson’s disease. To draw attention to this situation, a case of Parkinson’s disease with striatal hand deformity is presented. KW - striatal hand deformity KW - Parkinson’s hand deformity KW - hand deformity CR - 1.
