Hand tendon surgery incision design

The principle of designing a tendon surgical incision is that it should be parallel to the skin lines, palm prints, fingerprints, or with a beveled, curved incision to reveal the tendon. Treatment of diseases: hand flexor tendon injury hand tendon injury Indication Hand tendon injury. Contraindications 1, with systemic diseases, can not tolerate surgery. 2, local infection, not suitable for surgery. Preoperative preparation During the operation, 1 hour before the transplant is expected, a sterile table is additionally placed, which is separated from the surgical instrument vehicle to avoid pollution. The compound lactated Ringer's solution of 15-20 ° C was prepared in a rewarming container, and under the aseptic conditions, the cryopreserved allogeneic bone was taken out from the package in parallel with the first bacterial culture. The allogeneic bone was placed in the thermostatic compound lactated Ringer's solution for 15 minutes, and then taken out, and the second bacterial culture was performed. After washing for 5 min in an antibiotic solution (40,000 U gentamicin/100 ml), a third bacterial culture was performed. The allogeneic bone is ready. 1, patient preparation Patience and meticulous psychological care before surgery to eliminate patient tension and anxiety, in order to achieve a good match. Shave the hair in the surgical site, and cut the nails in the hands and feet. 2, 109HH artificial tendon selection: 1 carcass selection: carcass is a biological fiber, in the shape of a rope. Different types of artificial tendon bodies are selected according to the needs of the surgical site, such as ZBF3-10, ZBF6-20 for flexion and extension finger (toe), ZBF6-15, ZBF6-20 for knee collateral ligament and cruciate ligament, ZBF9 -10, ZBF9-15, ZBF9-20 are used for Achilles tendon. 2 membrane selection: membrane is a specially treated biofilm material. It can be a dry film and a wet film. It has two specifications, namely 5cm×2.5cm×(0.020.12)mm and 10cm×2.5cm×(0.020.12)mm. It can be selected according to the length of the carcass. membrane. 3. Suture: The specially treated biofibrous material can be gradually absorbed by the body in the body. Its specifications are the same as ordinary sutures. Surgical procedure 1. The design of the mid-incision of the finger side. Flex your fingers and mark them at the apex of the finger. 2. Connect the marker points into a line, which refers to the side median incision. Applicable to the exposure of the flexor tendon I and II regions. 3. Straighten your fingers and mark them on a line. 4, the palm side of the "Z"-shaped incision, can directly reveal the flexor tendon I, II area. The palm-striated incision and the large fish-grain incision are suitable for the flexor tendon III. 5, palm and forearm combined incision, can reveal the flexor tendon III, IV, V area. 6, refers to the dorsal ganglion transverse incision or "Z-shaped" incision, revealing the extensor tendon 1 area. The back of the "S"-shaped incision can reveal the extensor tendon II and III regions. 7, "S"-shaped incision in the back of the hand, wrist back and forearm, can reveal the extensor tendon III, IV, V area. complication Wound infection.
