Nail pathology is well described in systemic and central nervous system disorders. Patients with chronic hemiplegia can develop unilateral decrease in nail growth rate, dyschromic changes, and increases in nail plate convexity leading to fingernail clubbing. Nail clubbing, a beaked fingertip deformity, occurs because of hyperplasia of dermal fibrovascular tissue. Advanced clubbing involves bony destruction of the distal phalanges with osteoblast proliferation. Bilateral symmetric clubbing is classically seen in congenital heart disease and chronic pulmonary disease. Unilateral clubbing exclusively occurring because of hemiplegia is rare, only affecting about 2% of hemiplegic patients, and may result from local autonomic dysregulation.
