Abstract

The psychoflexed hand is a rare clinical condition characterized by fixed finger contractures undetermined by organic etiology, often associated with a psychiatric pathology. We report a series of 20 patients (nine males and 11 females, mean aged 56.2 years). We have introduced a new classification of the various possible patterns of finger deformities: 1) Type 1: prevalent flexion contracture at the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints of the last two or three fingers; the thumb and the index are not affected; 2) type 2: prevalent flexion contracture at the PIP and distal interphalangeal (DIP) joints of the last two or three fingers; 3) type 3: flexion contracture of all the long fingers; 4) type 4: flexion contracture of all the fingers of the hand, including the thumb (clenched fist syndrome); 5) type 5: isolated flexus-adductus thumb (the long fingers are not affected); 6) type 6: flexion of digits associated with flexion contractures of other joints of the upper extremity. The treatment was conservative in 14 patients with recent deformities and surgical in six patients. Both forms of treatment were followed by a rigorous rehabilitation program, mostly based on home self-rehabilitation. The correction of the deformities was obtained in all cases and maintained over time.
