Graft Tendonectomy

The palmar muscle tendon is often used as a transplanted tendon. The long extensor tendon of the toe is rarely used because of its poor quality and often has dysfunction in the donor area. If you need more than one transplant, you can use allogeneic tendon graft instead. Treatment of diseases: hand tendon injury Indication The palmar muscle tendon is often used as a transplanted tendon. The long extensor tendon of the toe is rarely used because of its poor quality and often has dysfunction in the donor area. If you need more than one transplant, you can use allogeneic tendon graft instead. Contraindications 1. The infection after the local injury has not been eliminated. 2. Injury refers to the passive flexion and extension of each joint. 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 and ZBF6-20 for flexion and extension fingers (toe); ZBF6-15 and 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. Before the palmar tendon is cut, the weight of the palmar tendon can be clearly observed to determine whether it is suitable or not. 2, at the end of the tendon of the palmar tendon, the site of the tendon, and the middle of the full length of the tendon, each made a 1.5cm transverse incision, and sneaked the tendon between the three incisions under direct vision, paying attention to protecting the periorbital tissue. 3. After the peeling is completed, the tendon is provoked and it is confirmed that it is a tendon rather than a median nerve. 4. The tendon is cut from the distal edge of the transverse ligament of the scapula and extracted from the proximal incision of the forearm. 5, according to the required length from the proximal side of the tendon cut off, remove the long palm tendon. complication Suppurative infection, infected wounds have pain, redness, tenderness, purulent secretions, etc., body temperature can be increased and neutrophils can be increased. Closed wounds may also be associated with various infections, such as post-injury aspiration, airway endocrine retention, and atelectasis secondary lung infections. Tetanus or gas gangrene may also occur after the injury, and the consequences are quite serious.
