Objective:To explore the clinical efficacy of staged reconstruction with anterolateral thigh flap (ALTF) for wrist-forearm soft tissue defects of electrical burns.Methods:A retrospective observational study was conducted on 10 patients who had wrist-forearm soft tissue defects after electrical burns and were admitted in the Department of Burns, Zhengzhou First People's Hospital from January 2019 to December 2022. The patients were 6 males and 4 females, aged 8 to 64 years. All the patients were third-and-fourth degree electrical burns. Debridement was performed to remove the necrotic tissues around the wound in stage I surgery. Area of the wound after debridement ranged from 15 cm×11 cm to 31 cm×20 cm. According to the condition of wrist-forearm injury, the wounds with relatively mild injury were retained. Free ALTF was used to cover the wound surface. Size of the flaps ranged from 16 cm×12 cm to 32 cm×21 cm. The descending branch of lateral circumflex femoral artery and the accompanying veins carried by the flap were anastomosed end-to-end with the radial artery and vein or ulnar artery and vein in the recipient site, respectively. Conditions of other vessels were explored. The great saphenous veins in a length of 10-18 cm was used to bridge the occluded arteries. The donor sites were covered by medium thick skin grafts from trunk. After survival of the flap, stage Ⅱ surgery was carried out to debride the wound temporarily retained in stage I surgery and to thin the flap, then had all the wound covered with the thinned flap. Follow-ups were conducted at outpatient clinic, and via telephone and WeChat interviews. The limb salvage, flap survival, vascular compromise and other complications, as well as the donor site healing were observed. The wound coverage rate of the thinned flap. The appearance of flap, donor site scar hyperplasia, the patient satisfaction with the shape and function of the donor site at 6 months after the stage Ⅱ surgery were evaluated. Likert scale was employed to evaluate the patient satisfaction. The Michigan Hand Outcomes Questionnaire (MHQ) and Disabilities of the Arm, Shoulder and Hand (DASH) were used to evaluate the upper limb function in daily life of the patients.Results:The limb salvages in the 10 patients were all successful, and the flaps survived without any postoperative event of vascular compromise or other complication. One patient had mild cyanosis at the edges of flap after surgery and regressed at 7 days later. One flap had poor blood circulation and partial necrosis. The thinned flaps covered the wound completely after the stage-Ⅱ flap thinning surgery. The postoperative follow-up period was 6.0-7.0 months. All skin grafts in the donor sites survived well. The thinned flaps of stage Ⅱ surgery achieved 100% in wound coverage rate. At 6 months after surgery, the colour and texture of the flaps were about the same as those of the normal skin of the upper limb. There were linear scars in both of donor and recipient sites. Four patients were satisfactory to the postoperative appearance and function of the donor site and 6 patients were very satisfactory. MHQ scores were 49-82 (mean, 74) points; DASH scores were 27-45 (mean, 32) points.Conclusion:Reconstruction of the wounds in wrist-forearm soft tissue defects of electrical burns with ALTF in staged surgery, can improve the function and aesthetics of the wrist-forearm. It is a good method.

Objective:To compare the clinical curative effects of saphenous artery flap and retrograde anterolateral femoral perforator flap in repairing full-thickness electric burn wounds deep to tendon and bone in the knee.Methods:This study was a retrospective observational study. From July 2018 to February 2022, 34 patients with full-thickness electric burn wounds deep to tendon and bone in the knee and conformed to the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 26 males and 8 females, aged 18 to 54 years. According to the repair method of the electric burn wounds in the knee, the patients were divided into saphenous artery flap group (18 cases) repaired with saphenous artery flap and anterolateral femoral flap group (16 cases) repaired with retrograde anterolateral femoral perforator flap. The exposed area of bone and/or tendon after debridement was 5 cm×4 cm to 12 cm×7 cm, 5 patients were combined with open joint, and the resected area of the flap was 9 cm×6 cm to 25 cm×12 cm in saphenous artery flap group; the exposed area of bone and/or tendon after debridement was 7 cm×5 cm to 15 cm×7 cm, 6 patients were combined with open joint, and the resected area of the flap was 15 cm×10 cm to 39 cm×25 cm in anterolateral femoral flap group. According to the resected width of the flap, the wounds in the flap donor areas were repaired by direct suture or medium thickness skin graft in the trunk. The survival of the flap was observed after surgery. At the last follow-up, the color and texture of the flap were observed, and the two-point discrimination distance of the flap was detected. The sensory recovery of the flap was evaluated using the trial standards for evaluation of partial function of upper extremity by the Hand Surgery Society of Chinese Medical Association, and the excellent ratio of sensory recovery was calculated. The function of knee joint was assessed using the Knee Subjective Score Scale of International Knee Documentation Committee. The repairing effect of the flap was evaluated using comprehensive evaluation scale of flap, and the excellent ratio was calculated.Results:Most of the flaps in patients in the 2 groups survived well after surgery, only 2 patients in the anterolateral femoral flap group had distal flap necrosis of 3 to 5 cm 2, which healed after skin grafting or local suture. At the last follow-up of 12 to 18 months after surgery, the color and texture of the flap in patients in the two groups were similar to those of the skin tissue in the knee. The excellent ratio of sensory recovery of the flap was 18/18 in patients in saphenous artery flap group, which was significantly higher than 5/16 in anterolateral femoral flap group ( P<0.05). The two-point discrimination distance of the flap was (11.7±1.5) mm in patients in saphenous artery flap group, which was significantly shorter than (21.5±1.7) mm in anterolateral femoral flap group ( t=-1.84, P<0.05). The score of the knee joint function and the excellent ratio of the repairing effect of the flap had no statistically significant differences in patients in the two groups ( P>0.05). Conclusions:The full-thickness electric burn wounds deep to tendon and bone in the knee can be repaired with saphenous artery flap and retrograde anterolateral femoral perforator flap. After being repaired with those two types of flaps, the function of the knee joint recovers well, while the sensory recovery is better after being repaired by the saphenous artery flap.

Objective:To investigate the clinical application effect of bypass vein bridging in repairing high-voltage electric burn wounds on the head with free anterolateral thigh flaps.Methods:This study was a retrospective observational study. From May 2017 to December 2022, 8 patients with high-voltage electric burns on the head who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 6 males and 2 females, aged 33 to 73 years. All patients had skull exposure, including 3 cases of large skull defect, 1 case of left eye necrosis, and 3 cases of cerebral hemorrhage. After debridement, the head wound area was from 13 cm×7 cm to 21 cm×15 cm, and the free anterolateral thigh flap with the area of 14 cm×8 cm to 22 cm×16 cm was cut for repair. The main descending branch of the lateral circumflex femoral artery carried by the flap was anastomosed end-to-end with the superficial temporal artery in the recipient area. One accompanying vein of the anastomotic artery of the flap was end-to-end anastomosed with the branch of the external jugular vein via great saphenous vein bridging, and the other accompanying vein was end-to-end anastomosed with the superficial temporal vein in the recipient area. The donor site wounds were directly sutured or closed with medium-thickness skin grafts from inner thigh. The blood supply and survival of the flap, and the wound healing on the head were observed after operation. The blood flow and lumen filling of the transplanted vein were observed and recorded by using color ultrasound diagnostic system within 2 weeks after operation. The wound repair method and wound healing of the flap donor site were recorded and observed. Patients were followed up to observe the appearance of the flaps and the flap donor sites, the muscle strength of the lower limbs where the flap donor site was located, and whether the patient could complete standing, walking, and squatting using the lower limbs where the flap donor site was located.Results:The flaps of 8 patients survived after operation, and no arterial or venous crisis occurred. The wounds of 5 patients on the head healed after operation, and the wounds of 3 patients on the head healed after second debridement 21 to 35 days after operation due to exudates under the flap 2 weeks after operation. Within 2 weeks after operation, the grafted vein continued to be unobstructed. After the ultrasound probe was pressurized, the grafted vein could be deflated, and the blood vessels were rapidly filled after the probe was released. The wounds of flap donor sites of 3 patients were directly sutured and healed 2 weeks after operation. The wounds of flap donor sites of 5 patients were closed with medium-thickness skin grafts from inner thigh, and all the skin grafts survived 12 days after operation. During follow-up of 6 to 12 months, the head flaps of all patients were slightly bloated without hair growth. Mild linear or patchy scar hyperplasia was left in the donor site. The muscle strength of the lower limbs where the flap donor site was located was normal and did not decrease. The patients could stand, walk, and squat with the lower limbs where the flap donor site was located.Conclusions:When using the free anterolateral thigh flap to repair high-voltage electric burn wounds of various areas and depths on the head, bypass vein bridging can reduce the occurrence of postoperative flap vein crisis and improve the quality of postoperative wound healing without affecting the function of the lower limbs where the flap donor site is located.

Objective:To explore the effects of free gracilis muscle flap combined with sural nerve transfer for reconstruction of digital flexion and sensory function of hand in patient with severe wrist electric burn.Methods:A retrospective observational study was conducted. From January 2017 to December 2020, 4 patients with wrist high-voltage electric burn admitted to the Department of Burns of the First People's Hospital of Zhengzhou and 4 patients with wrist high-voltage electric burn admitted to the Department of Hand Surgery of Beijing Jishuitan Hospital met the inclusion criteria, including 6 males and 2 females, aged 12 to 52 years. They were all classified as type Ⅱ wrist high-voltage electric burns with median nerve defect. In the first stage, the wounds were repaired with free anterolateral thigh femoral myocutaneous flap. In the second stage, the free gracilis muscle flap combined with sural nerve transplantation was used to reconstruct the digital flexion and sensory function of the affected hand in 3 to 6 months after wound healing. The cut lengths of muscle flap and nerve were 32 to 38 and 28 to 36 cm, respectively. The muscle flap donor area and nerve donor area were both closed and sutured. The survival condition of gracilis muscle flap and sural nerve, the wound healing time of recipient area on forearm, the healing time of suture in muscle flap donor area and nerve donor area were observed and recorded after operation, and the recovery of donor and recipient areas was followed up. In 2 years after operation, the muscle strength of thumb and digital flexion and finger sensory function after the hand function reconstruction were evaluated with the evaluation criteria of the hand tendon and nerve repair in the trial standard for the evaluation of functions of upper limbs of Hand Surgery Society of Chinese Medical Association.Results:All the gracilis muscle flap and sural nerve survived successfully after operation. The wound healing time of recipient area on forearm was 10 to 14 days after operation, and the healing time of suture in muscle flap donor area and nerve donor area was 12 to 15 days after operation. The donor and recipient areas recovered well. In the follow-up of 2 years after operation, the muscle strength of thumb and digital flexion was evaluated as follows: 4 cases of grade 5, 3 cases of grade 4, and 1 case of grade 2; the finger sensory function was evaluated as follows: 4 cases of grade S3 +, 2 cases of grade S3, and 2 cases of grade S2. Conclusions:For patients with hand dysfunction caused by severe wrist electric burn, free gracilis muscle flap combined with sural nerve transplantation can be used to reconstruct the digital flexion and sensory function of the affected hand. It is a good repair method, which does not cause great damage to thigh muscle flap donor area or calf nerve donor area.

Objective:To explore the curative effects of foot microflap free transplantation in the repair of full-thickness electric burn wounds deep to tendon or even bone in fingers.Methods:A retrospective observational study was conducted. From July 2017 to February 2022, 20 patients with full-thickness electric burn wounds deep to tendon or even bone in fingers who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 19 males and 1 female, aged 18 to 64 years. Among the 20 wounds, 15 wounds were located on the palm side, including 8 on the thumb, 5 on the index finger, and 2 on the middle finger; 5 wounds were located on the back, including 1 on the index finger and 4 on the middle finger. After debridement, the wound area ranged from 4.5 cm×2.0 cm to 7.0 cm×3.0 cm. According to the principle of tissue structure similarity, 10 wounds were repaired with plantar medial flaps, 5 wounds were repaired with hallux peroneal flaps, and 5 wounds were repaired with dorsalis pedis artery flaps, with flap area of 5.0 cm×2.5 cm-8.0 cm×3.5 cm. The flaps were transplanted freely and arteries and veins and/or nerves were anastomosed at the same time. The wound in the donor site was repaired with thigh medium-thick skin graft. The survival of flaps and skin grafts were observed after surgery. The appearance of flap, temperature and color of the distal end in the affected finger were observed during follow-up. At the last follow-up, the joint function and flap sensory recovery of the affected finger were evaluated with the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association; the two-point discrimination distance of skin in the area of flaps with nerve anastomosis was measured; the satisfaction of patients with the curative effect was investigated by using the curative effect satisfaction rating scale, and the very satisfied rate was calculated; the repair effect of flap was evaluated by the comprehensive evaluation scale, and the excellent and good rate was calculated.Results:All the flaps and skin grafts survived after surgery. During the follow-up of 10-18 months after surgery, the appearance of flap was natural and not bloated; the temperature and color of the distal end in the affected finger were basically the same as that of normal finger skin. At the last follow-up, the function recovery of the affected finger joints was as follows: 11 affected fingers were within the normal range of motion, 6 affected fingers had their total active range of motion recovered to 85% of the healthy side, and 3 affected fingers had their total active range of motion recovered to 75% of the healthy side; the flap sensory recovery was as follows: the sense of 15 flaps with nerve anastomosis all recovered to grade S3 +, and the two-point discrimination distance of skin in the flap area was 7.0-9.0 mm; the sense of 1 flap without nerve anastomosis recovered to grade S2 and the sense of 4 flaps recovered to grade S1. The satisfaction with curative effect of 20 patients was very satisfied in 16 cases and moderately satisfied in 4 cases, with the very satisfied rate of 80%; the repair result of 20 flaps was excellent in 16 cases, good in 2 cases, and fair in 2 cases, with excellent and good rate of 90%. Conclusions:Due to the similar tissue structure of donor site and recipient site, foot microflap free transplantation in the repair of full-thickness electric burn wounds deep to tendon or even bone in fingers can achieve good appearance and function, with better functional and sensory recovery of the affected finger in the case of nerve anastomosis. Patients have high degree of satisfaction with the curative effects, which is worthy of promotion.

Objective:To explore the curative effects of ultrathin anterolateral femoral flap in one-stage split-finger repair of palmar combined with multiple finger wounds.Methods:A retrospective observational study was conducted. From October 2016 to June 2018, 20 patients with wounds on palms and multiple fingers who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 15 males and 5 females, aged 18 to 77 years. After debridement, the wound area was 8 cm×4 cm-17 cm×12 cm. The wound was repaired by ultrathin anterolateral femoral flap with area of 9 cm×5 cm to 19 cm×13 cm. According to the wound condition of finger, the finger division was performed in one stage, and the length-to-width ratio of the split-finger flap was 2.0:1.0-2.5:1.0. During the surgery, the descending branches of lateral circumflex femoral artery and accompanying vein of flap were anastomosed end-to-end to the radial artery and vein in the recipient area, respectively, and the anterolateral femoral cutaneous nerve of flap was bridged with the superficial branch of radial nerve in the recipient area. The wounds in the donor area of flap in 14 patients were sutured directly, the wounds in the donor area of flap in 3 patients were repaired by relay superficial iliac circumflex artery perforator flap, and the wounds in the donor area of flap in 3 patients were covered by free trunk medium-thick skin graft. The survival of flap, occurrence of vascular crisis and other complications, and healing of wounds in the donor area of flap were recorded. The appearance of flap, scar hyperplasia in the donor and recipient areas and the patients' satisfaction with the shape and function of the donor and recipient areas were followed up. In 1 year after surgery, the two-point discrimination distance of the flap was measured, and the recovery of hand function was evaluated by the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association.Results:The flaps of 17 patients survived without vascular crisis or other complications after surgery. The flap of 1 patient had poor blood circulation and partial necrosis, and the wound was healed 14 days after dressing change and grafting of split-thickness skin graft from head. Two patients had mild cyanosis at the margin of flap after surgery, which disappeared spontaneously 5 days later. Incisions at donor site, relay flaps, and skin grafts of all patients survived well. After surgery, the color and texture of flap were basically the same as that of the normal skin of hand, and linear scars were observed in the donor and recipient areas. The patients were satisfied with the recovery of appearance and function of donor and recipient areas. After 1 year of follow-up, the patients' hand sensory function recovered well, the two-point discrimination distance of flap was 4-6 mm, and the recovery of hand function was evaluated as excellent in 18 cases and good in 2 cases.Conclusions:The ultrathin anterolateral femoral flap in repairing the palmar combined with multiple finger wounds in one-stage split-finger can significantly reduce the number of surgeries and improve the function and beauty of the hand, so it is worthy of clinical promotion.
