Hand Deformity in Parkinson’s Disease: A Case of Striatal Hand Deformity Mimicking Rheumatoid Arthritis

Öz

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.
