Digital extensor tendon suture, zone I

It is suitable for the old puncture of the affected finger. The last section can not actively stretch, and the active flexion and passive straightening are good. Treatment of diseases: tendonitis, hand tendon injury Indication It is suitable for the old puncture of the affected finger. The last section can not actively stretch, and the active flexion and passive straightening are good. 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 1. Edema and inflammation of the limbs and wards, even if mild, should be actively treated, so that it completely disappears after 2 to 3 months of surgery. 2. Local large and hard scars should be removed first and the flaps should be repaired to ensure a good blood supply and a soft loose tissue bed around the tendons. 3. Before the tendon is sutured, the joint stiffness of the dominant tendon should be treated first, and the physical therapy and active and passive exercise should be given to restore the greater activity, so that the effect of the tendon suture can be operated and received. 4. The suture material should be selected from the varieties with small reaction, large pulling force and smooth surface. Generally, soft stainless steel wire with a diameter of 0.25 to 0.30 mm is preferred, and is mostly used for drawing steel wire stitching. Tendons with small or small diameters can be sutured with Nilon monofilament. Filament thread suture has a certain degree of tissue reaction, mostly used for Bunnell burial suture, but the silk thread must be able to withstand 1 to 1.5 kg of tensile force. 5. Prepare a slender straight round needle for suturing the tendon. Surgical procedure 1, cut the skin, pay attention not to hurt the nail, revealing the extensor tendon. See the extensor tendon rupture proximal to the interphalangeal joint capsule, the two ends are connected by thin scars. Make an "H" cut between the scar and the tendon. 2. The broken end is slightly free for suturing. 3, the assistant will flex the proximal interphalangeal finger, the distal interphalangeal joint is overextended, and the two ends of the fracture can be close to each other or overlap each other. 4, with 5 / 0 non-invasive needle thread, the broken end (partially scar) overlap stitching 4 needles. 5. Stitch the skin incision. A thin plaster bandage was used to make the finger tube type, and the proximal interphalangeal joint was fixed at the flexion position and the distal interphalangeal joint was overstretched for 6 weeks. 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.
