Summary

Primary repair for flexor tendon lacerations remain the standard of care. However, despite recent advances in knowledge of tendon healing, suture material, and post-operative protocols, outcomes have been reported as fair or poor in 7-20% of patients. Complications encountered include adhesion formation, development of joint contractures, tendon rupture, triggering, bow stringing and quadriplegia. Tendon surgery is unique because it should ensure tendon gliding after surgery Tendon surgery now can be performed under local anesthesia without tourniquet, by injecting epinephrine mixed with lidocaine, to achieve vasoconstriction in the area of surgery. This method allows the tendon to move actively during surgery to test tendon function intraoperatively and to ensure the tendon is properly repaired before leaving the operating table.

Wide awake hand surgery is well described by its other name, WALANT which stands for wide awake local anaesthesia no tourniquet. The only two medications most patients are given for wide awake hand surgery are Lidocaine for anaesthesia and epinephrine for haemostasis. In the period before 1950, the belief developed among surgeons that epinephrine causes finger necrosis .The source of the epinephrine myth stemmed from the use of procaine (Novocaine). It was the only safely injectable local anaesthetic until the introduction of Lidocaine in 1948. More fingers died from procaine injection alone than from procaine plus epinephrine injection .no lost finger no case require phentolamine in many studies.
