Closed ruptures of the deep flexor tendons are rare, even though they occur more often than those of the superficial flexor tendons. We report about a closed distal rupture of the deep flexor tendon of the little finger as experienced by a 50-year-old man who suffered an injury at work. The proximal stump allocated to the torn flexor tendon of zone I had noticeably pulled back to the middle of the palm of hand, and had come to rest around the tendon of the ring finger. We illustrate the problems linked with diagnosis, care and follow-up treatment of such a case.
