Hand clenching Thumb clasp HP:0001188 Hands fisted Hand clenching is commonly characterized by malpositioning of the fingers characterized by radial deviation of the 4th and 5th digits and ulnar deviation of the 2nd digit over the 3rd finger. Hand clenching is distinguished from Camptodactyly, as that term may describe fewer than five digits of a eudactylous hand and does not involve the MCPJ. The digits may overlap when they lie flexed in the palm. It is not necessary to specify the overlapping fingers finding separately. Clenched hand Hand clenching Fisted hand Fisting Clenched hands Hands tightly fisted An abnormal hand posture in which the hands are clenched to fists. All digits held completely flexed at the metacarpophalangeal and interphalangeal joints. In prenatal sonography of the fetal clenched hand, the index finger overlaps a clenched fist formed by the other digits. The proximal interphalangeal articulation of the index finger is flexed and ulnarly deviated, and the thumb is adducted. UMLS:C0239815 Abnormal hand morphology
