Finger Contracture Associated with Forearm Infection Mimicking Neurogenic Claw Hand Deformity

초록

Claw hand deformity is produced by imbalance of the intrinsic and extrinsic hand muscles. It can be caused by peripheral neuropathies such as median or ulnar neuropathy, hereditary motor sensory neuropathies and spinal cord disorders. We have experienced selective flexion deformity of the ring and little fingers resembling a mild type of claw hand deformity resulted from soft tissue infection within the deep flexor muscle of the forearm in a middle-aged woman.
