Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The hand is divided into five zones (Verdan's). Zone II is described by Bunnel as "No Man's Land" historically back to 14th century (area outside London used for executions) because it was previously believed that primary repair should not be done in this zone. After understanding of flexor tendon anatomy, biomechanics , and healing new techniques of surgery and anesthesia repair is possible with good results.
General anesthesia has been the standard technique for along time. wide awake local anesthesia no tourniquet. (WALANT),using safe drugs lidocaine for anesthesia and epinephrine for hemostasis, the investigators can do operations while patient is awake.
WALANT has been recommended by some surgeons to be the next standard for repair of zone 2 injuries .
This techniques has a lot of Advantages in repair zone II as 1) intraoperative testing of the flexor repair by active movement to exclude any gap. and lets the surgeon see that the repair fits through the pulleys with active movement.
2)sheath and pulley damage are minimized, as flexor tendons are repaired through small transverse sheathotomy incisions 3) the surgeon can interview the patient during the procedure and assess the ability to comply with the postoperative regimen 4) the risks of general anesthesia are avoided in most patients. Negative effects of general anesthesia include nausea and vomiting, hospital admission for anesthesia recovery, exacerbation of comorbidity issues such as diabetes, aggressive flexion by the patient emerging from general anesthesia,and others
