A 14 months old boy presented with limitations of movement in his index, middle and ring fingers of both hands since birth. On examination, his affected fingers were stiff and flexion was present only at metacarpophalangeal joint. Flexion movement was restricted
at the interphalangeal joints (both proximal and distal). There was no local swelling or tenderness. All the other joints, bones and systems were normal. X ray of both the hands revealed bony fusion at proximal interphalangeal joint.
