ABSTRACT
Objective To discuss the method and clinical effect of bilobed DIEP flap for repair of degloving injuries of the hand.Methods From June, 2013 to January, 2015, the bilobed DIEP flap were designed to repair 6 cases of degloving injuries of hand, of which the small leaf flap repaired separately defect of thumb, larger leaf flap repair 2nd-5th finger and palm and dorsum.The bilobed DIEP flap design were based upon anatomic study on deep inferior epigastric artery, superior epigastric artery, intercostal artery and its anastomosis.Results The largest area of main flap was 35 cm × 12 cm, and the deputy leaves of flap was 10 cm× 7 cm.All of the 6 flaps survived.One of them experienced distal end necrosis of epidermis.But it was healed by dressing changes.All of the 6 cases were followed up for average of 12 months (range, 6-20 months).All flaps were seen with good appearance, fully recovered protectve sensation and the active motion of the thumb was recovery.Moreover, the donor sites were closed directly and the appearance were satisfactory.Conclusion The bilobed DIEP flap is a satisfying choice in repairing degloving injuries of the hand in that it has reliable blood supply, can obtain the larger area of skin and leaves small injuries in targeted area.
ABSTRACT
Objective To determine the surgical approaches and evaluate the clinical efficacy of skin defects of the emergency thumb, finger reconstruction.Methods Emergency in 11 cases complicated skin defect of the thumb and the hand, fingers missing injured patients by using the method of combined of toenail flap of biped dorsalis pedis flap or the second toe.The implantation of thumbnail flap of dorsalis pedis flap combined with the second toenail flap was applied on 5 cases.3 cases had received the implantation of thumbnail flap of dorsalis pedis flap combined with the second toe and 3 cases with combined repair of the second toe of biped dorsal flap.Of all the cases, reconstruction of 3 fingers in 1 case, reconstruction of 2 fingers in 10 cases,5 cases with reconstruction by means of implantation of toenail flap of same pediele splitting flap or the second toe, 6 cases with repair of toenail flap of dorsalis pedis flap or second toe.Results Except for 1 necrosis occurred in 1 finger in 1 case of 3 fingers reconstruction, the rest of tissue flaps and fingers all survived.The primary healing was achieved postoperatively.The patients were followed up for 5-24 months.The functions such as grabbing, grasping, nipping were basically restored after the repair.The appearance of hand was also restored to a certain degree.Sensory recovery S2-S4 of reconstruction finger and flap was achieved.Healing was satisfying in the donor area, no obvious cicatricial contracture was seen, while the walk function was not affected.Conclusion The application of combined implantation of toenail flap of biped dorsalis pedis flap or the second toe in the repair of overall hand skin degloving injury could restore the function and appearance of the injured hands to a certain degree.It is proved to be an effective treatment method.
