OBJECTIVE: To evaluate the clinical result of repairing degloving injury of hand with abdominal bipedicled subdermal vascular-network flap in emergence. METHODS: From 1994 to 1997, 19 cases with degloving injury of hand were treated with two flaps, one flaps with the inferior epigastric artery as pedicle, another with superficial epigastric artery. The two skin flaps were designed oppositely to cover the injured hands. RESULTS: All the flaps survived. Followed up for 1 to 3 years, the contour of hands were fine. Extension of fingers was normal and opponers of thumbs was good. Range of flexion of metacarpo-phalangeal joints was from 45 to 60 degrees, and the proximal interphalangeal joints was from 10 to 25 degrees. CONCLUSION: For the subdermal vascular network, the bipedicled flaps of abdomen in repair of degloving injury of hand have sufficient blood supply, b resistance to infection, high survival rate, and good contour.
Objective?To investigate the surgical method and clinical efficacy of repairing whole-hand destructive injury or hand degloving injury with the transplant of pedis compound free flap.?Methods?From February 2003 to June 2008, 21 patients with whole-hand destructive injury or hand degloving injury were treated, including 15 males and 6 females aged 18-45 years old (average 25 years old). The injury was caused by punching machine crush in 10 cases, roller crush in 7 cases, and imprinter crush in 4 cases. The time between injury and operation was 1-9 hours. Eleven cases had the skin-degloving injury of the whole hand, while the other 10 cases had the proximal palm injury combined with dorsal or palmar skin and soft tissue defect. After debridement, the size of wound was 9 cm × 7 cm - 15 cm × 10 cm in the dorsal aspect and 10 cm × 7 cm -16 cm × 10 cm in the palmar aspect. The defect was repaired by the thumbnail flap of dorsalis pedis flap and the second toenail flap of dorsalis pedis flap in 5 cases, the thumbnail flap of dorsalis pedis flap and the second toe with dorsalis pedis flap in 4 cases, and bilateral second toe with dorsalis pedis flap in 12 cases. The flap area harvested during operation ranged from 6 cm × 5 cm to 16 cm × 11 cm. Three fingers were constructed in 2 cases and two fingers in 19 cases. Distal interphalangeal joint toe amputation was conducted in the thumbnail flap donor site, metatarsophalangeal joint toe amputation was performed in the second toenail flap donor site, and full-thickness skin grafting was conducted in the abdomen.?Results?At 7 days after operation, the index finger in 1 case repaired by the second toenail flap suffered from necrosis and received amputation, 1 case suffered from partial necrosis of distal dorsalis pedis flap and recovered after dressing change, and the rest 42 tissue flaps survived. Forty-three out of 44 reconstructed fingers survived. All the wounds healed by first intention. At 2 weeks after operation, 2 cases had partial necrosis of the donor site flap and underwent secondary skin grafting after dressing change, the rest skin grafts survived, and all the wounds healed by first intention. Nineteen cases were followed up for 6-36 months (average 11 months). The flaps of palm and dorsum of hand showed no swelling, the reconstructed fingers had a satisfactory appearance and performed such functions as grabbing, grasping, and nipping. The sensory of the flaps and the reconstructed fingers recovered to S2-S4 grade. The donor site on the dorsum of the foot had no obvious scar contracture, without obvious influence on walking.?Conclusion?For the whole-hand destructive injury or hand degloving injury, the method of transplanting pedis compound free flap can repair the defect in the hand and reconstruct the function of the injured hand partially. It is an effective treatment method.
Objective To investigate the effectiveness of reverse island flaps of digital artery parallel for repairing degloved injuries of the fingerti p. Methods Between June 2008 and January 2010, 13 cases of degloved injuries of the fingertip were treated. There were 8 males and 5 females with an average age of 34 years (range, 19-62 years). The causes of injuries were as follow: impact and press injury in 5 cases, wringer injury in 7 cases, and crush injury in 1 case. The injured fingers were comprised of index finger in 6 cases, middle finger in 4 cases, ring finger in 2 cases, and l ittle finger in 1 case. The size of skin and soft tissue defect ranged from 2.0 cm × 1.8 cm to 3.0 cm × 2.5 cm. Three cases compl icated by fracture of thedistal phalanx, 1 case by rupture of the insertion of extensor tendon, and 1 case by rupture of the insertion of flexor tendon. The average time from injure to surgery was 4 hours (range, 1 hour and 30 minutes-12 hours). Two neighboring skin flaps located in the same course of digital artery were adopted to repair defect of the fingertip. The size of proximal skin flap ranged from 1.2 cm × 1.0 cm to 2.0 cm × 1.5 cm and the size of distal skin flap ranged from 1.1 cm × 1.0 cm to 1.5 cm × 1.3 cm. The free skin grafts were used to repair the donor sites. Results Circulation crisis occurred in 1 case at 2 hours after operation and was el iminated by interval disconnecting. The other flaps and skin grafts survived and the wounds healed by first intention. The patients were followed up 6-18 months (mean, 10 months). All flaps presented the satisfactory appearance and texture, and the flexion and extension function of wounded fingers recovered to normal. Two-point discrimination ranged from 7 to 11 mm at last follow-up. According to the functional assessment criteria of upper l imb formulated by the Hand Surgery Branch of Chinese Medical Association, the results were excellent in 9 cases, good in 3 cases, and fair in 1 case with an excellent and good rate of 92.3%. Conclusion Based on the anatomical features of communicating branches of distal interphalangeal joint, two neighboring flaps located in the same course of digital artery are adopted to repair soft tissue defect of the fingertip. This surgical method is a simple and effective method.
OBJECTIVE: To explore a new surgical management of multiple fingers degloving injury. METHODS: In 1994 to 1997, 47 cases with multiple fingers degloving injury were sutured by two reverse "s"-type skin flaps on abdominal flank. RESULTS: The skin flaps in 46 cases survived and the wounds obtained primary heal. CONCLUSION: The application of abdominal flank "s"-type skin flap is reliable and convenient in the treatment of multiple fingers degloving injury.
OBJECTIVE In order to solve the difficult problem of one-stage repair of degloving injury of multiple fingers, the common pedicled ilio-inguinal-hypogastric subdermal vascular network skin flap was designed and the multi-lobes skin flap was performed subsequently. METHODS From 1993 to 1996, there were 5 cases with degloving injuries of multiple fingers were treated by this flap. There were 2 males and 3 females and the age ranged from 7 to 19 years old. RESULTS After operation, the pedicles of the flap was detached between 12 to 16 days and all of the flaps survived completely. Patients were followed up for 6-18 months. After repair, the contour and skin colour of the digits were excellent, and the motion of the interphalangeal joints and skin sensation were good. CONCLUSION The conclusion was as follows: The newly designed skin flap was characterized by the advantages of duration of treatment being short, excellent contour and more rapid recovery of function. It could be used for one-stage repair of degloving injury of multiple fingers.
Objective To investigate the effectiveness of the combination of the anterolateral thigh perforator (ALTP) flap and other flaps for repairing the extreme circumferential defects on the limb. Methods Between October 2016 and June 2019, 9 patients with the extreme circumferential defects on the limb were admitted, which resulted by degloving injury, including 8 males and 1 female with a median age of 42 years (range, 32-65 years). The etiology involved twist injury in 5 cases, traffic accident in 2 cases, and high voltage electric injury in 2 cases. The location of the defects was left forearm in 2 cases, right forearm in 3, left foot in 3, and right foot in 1. The injected wound bed followed by the exposure of bone, joint, tendon, and blood vessel. The dimension of defects was 25 cm×20 cm to 40 cm×28 cm. The period between the injury and admission was 1-12 hours (mean, 5 hours). All contaminated wounds were taken thorough and radical debridement and covered by the vacuum sealing drainage device during the emergency operation. The ALTP flap and the other one flap were tailored according to the dimension of the wound when the wound surface became granulating, including the thoracodorsal artery perforator (TAP) flap in 3 cases, superficial inferior epigastric artery perforator flap in 3 cases, superficial circumflex iliac artery perforator flap in 3 cases. And the donor site was primary closure. Results After operation, all the flaps survived except 1 case of partial necrosis at the edge of TAP flap and healed after secondary skin grafting, and the wounds in the donor and recipient areas healed by first intention. All patients were followed up 14-24 months (mean, 16 months). The shape of the flap was satisfactory and the texture was soft. There was no abnormal hair growth and obvious pigmentation during the follow-up. Only linear scar was left in the donor area, there was no complication such as abdominal wall hernia, and the activity of hip and knee was not affected. The functional reconstruction of upper limb and ankle was satisfactory, and the disabilities of the arm, shoulder, and hand (DASH) score was excellent in 4 cases and good in 1 case; the American Orthopaedic Foot and Ankle Association (AOFAS) score was excellent in 3 cases and good in 1 case. Conclusion ALTP flap combined with different flaps can reconstruct the circumferential extreme defects after limb damage in one-stage, which can achieve limb salvage to the greatest extent.
