Finger trauma amputation repair

The soft tissue of the hand is freshly damaged and can be used for this operation. After the wound on the palm of the palm of the finger is thoroughly debrided, a partial flap is formed on the lateral side of the finger or on the side of the ruler, and the cover is rotated. The flap is preferably cut on the side of the ruler to preserve the normal sensory function of the skin on the side of the finger. The remaining donor skin wounds need to be closed with a medium-thickness skin graft. If the wound is large or because of local limitation, it should not be repaired with a local flap. It can be repaired with a distal flap. The skin of the upper arm and forearm is thin and detailed, and the thickness is suitable for the repair of finger skin defects. Treatment of diseases: hand trauma, open hand injury Indication The soft tissue of the hand is freshly damaged. Preoperative preparation 1. Injection of tetanus antitoxin. 2. Prophylactic antibiotics. Surgical procedure (1) Cross-cutting repair of the distal end of the finger: Commonly used are VY forming (propelled flap repair) and rotating flap repair. 1. VY forming technique: after debridement, remove part of the phalanx end, which is 0.3~0.5cm shorter than the surrounding soft tissue; then V-shaped incision on both sides of the finger end, and draw the flaps on both sides to the midline Stitched, covering the fingertips. Finally, the V-shaped skin defect remaining on both sides is made into a Y-shaped suture. 2. Rotating flap repair: The local flap formed by the annular bulge on the dorsal side of the injured finger is covered and repaired on the phalanx end. Due to the large degree of looseness of the skin at the annular ridge, the wound left in the donor area can be closed by direct suturing. (B) finger oblique truncation repair: after debridement, bite the exposed phalanx, flattened the end of the bone, the finger nerve pulled out 0.5cm, cut with a sharp knife. The surrounding subcutaneous tissue is then covered with the exposed phalangeal end. After suturing, the longer side of the volar flap was used to invert to the dorsal side, and the suture was directly sutured to close the wound. (C) distal interphalangeal joint plane truncation repair: after debridement, the finger nerve is pulled out 0.5cm and then cut with a sharp knife, the flexor tendon is trimmed and sewed and fixed with the surrounding tissue, and then the exposed articular surface cartilage Bite and twilight, making the end elliptical. The skin on both sides was sutured after being cut out. A flap (or flap) graft can also be used to close the wound. Finger traumatic fingering, such as short injury time, clean and tidy wounds, should be re-planted with the fingers to maximize the recovery of hand function. Especially the thumb and index finger, it is better to replant.
