Abstract

Intrinsic paralysis can be the manifestation of a variety of pathologic entities (stroke, cerebral palsy, Charcot-Marie-Tooth, muscular dystrophy, leprosy, trauma, cervical disease, and compressive and metabolic neuropathies). Patients present with a spectrum of clinical findings dependent on the cause and severity of the disease. The 3 main problems caused by intrinsic weakness of the fingers are clawing with loss of synchronistic finger flexion, inability to abduct/adduct the digits, and weakness of grip. Clawing is defined as hyperextension of the metacarpophalangeal joints and flexion of the interphalangeal joints. This article describes the clinical evaluation and surgical treatment options for claw hand.
