Flexor tendon lengthening in zone II injuries

Primary repair of acute severed flexor tendons in zone II has replaced the "no-man's-land" concept, which advocates secondary procedures. Primary repair can be difficult when there are severe soft-tissue and bony injuries, and may lead to unfavorable results. The authors describe a technique that is simple, quick, and safe, and eliminates the need for tendon harvesting or other secondary procedures. It can also be used when a flexor profundus tendon gap occurs due to the injury.
