RESUMEN
OBJECTIVE: Electrical contact burns of the scalp cause serious morbidity and mortality. Early necrotic bone debridement and flap cover are crucial for successful wound closure. 18 F Sodium Fluoride (NaF), with high bone-to-soft tissue activity ratio, is useful for bone viability assessment. This study evaluated the role of 18 F NaF PET-computed tomography (CT) in objectively defining the extent and depth of nonviable calvarial bone, to guide adequate bone debridement. METHOD: Of 20 patients referred to our institute with electrical contact burns of the scalp during a 2-year period, 15 were enrolled in the study. Two weeks after the initial management, tracer uptake pattern was noted on 18 F NaF PET-CT of the head and exposed bone measured. Surgical bone debridement was based on scan findings, followed by wound closure. All patients underwent clinical evaluation and follow-up scan 3 months after surgery. RESULTS: Eight patients showed a central photopenic area in the exposed bone (maximum standardized uptake value [SUVmax] of 0.76 ± 0.14 with mean maximum dimensions 4.10 ± 1.76/2.67 ± 1.54 cm). High tracer uptake (SUVmax, 9.66 ± 6.03) was seen peripheral to the exposed bone (mean maximum dimensions, 8.14 ± 3.03/4.75 ± 1.61 cm). Postoperatively, there was no significant change in tracer uptake in the central debrided region or peri-debridement bone area under the flap. Clinically all patients showed a well-healed flap. CONCLUSION: 18 F NaF PET-CT appears useful for objective evaluation of skull bone viability and planning necrotic bone debridement in patients with electrical contact burns. However, additional studies with longer patient follow-up are required to validate these results.

Electrical burns pose unique challenges in reconstructive surgery due to the extensive tissue damage they cause. The thumb is particularly susceptible to electrical burns, leading to severe functional impairment. This case series introduces the use of the temporal fascia free flap for thumb coverage in patients with electrical burn injuries. The study aims to assess the functional outcomes of this approach using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Six male patients underwent thumb reconstruction using temporal fascia free flaps following electrical burn injuries. The extent of the injury was assessed, and necrotic tissue was debrided. Functional outcomes were evaluated using the DASH questionnaire 6 months postoperation. All procedures were conducted in accordance with ethical guidelines, and informed consent was obtained from all patients. All patients achieved successful transplants using temporal fascia free flaps. The average DASH score at the 6-month follow-up indicated satisfactory functional recovery. Patients reported improvements in thumb mobility and functionality, and the cosmetic appearance of the thumb was acceptable. The appearance of the scar in the donor area was well-received. The temporal fascia free flap proved to be an effective method for thumb reconstruction following electrical burn injuries. Its thin and flexible nature allows for optimal contouring and improved range of motion. Although one case of partial flap loss was observed, overall functional and aesthetic outcomes were satisfactory. Further research with larger sample sizes is warranted to optimize surgical techniques and postoperative care for better outcomes.

Advancements in technology allow for the utilization of low-voltage battery-powered devices for patients admitted to the hospital. There have been rare cases of burns due to leakage of the internal contents from low-voltage batteries, but to date, there have been no reports of electrical burns caused by low-voltage batteries. We present the case of an 89-year-old female who presented to the general surgery service with a suspected electrical burn from laying on a 9-volt battery. The patient underwent operative debridement with no evidence of a deeper injury. The patient continues to follow up with an outpatient wound clinic and is healing well. This case highlights the importance of teaching and raising awareness of all small devices that may become entangled or lost in patients' linens, such as 9-volt telemetry batteries, to prevent harm.

Volar finger contractures can be challenging for plastic surgeons. The dorsal metacarpal artery perforator (DMCAP) flap is frequently used to cover bones, tendons, and neurovascular structures in the dorsum of the hand after trauma and burns as an alternative to grafts and free flaps. We aimed to report volar finger defect reconstruction with expanded DMCAP flap. A 9-year-old male patient applied to our clinic with the complaint of inability to open the second finger of the left hand after an electrical burn that caused proximal and distal interphalangeal joints flexion contractures. Reconstruction was planned for the patient with a two-session expanded first DMCAP flap. A 16 mL 5 × 3 cm tissue expander was placed in the prepared area from the vertical incision in the first session. The tissue expander was inflated with 4 mL of isotonic solution. The DMCA area was enlarged 6 weeks later by giving 22 mL of isotonic solution. After the pedicle dissection, the 9 × 3 cm DMCAP flap was elevated by dissection over the paratenon. With 180° of rotation, the left-hand second finger was adapted to the 6 × 2 cm defect area on the volar face. The flap donor site was closed primarily. The operation was terminated by placing the hand on a protective splint. There were no complications in the flap in the postoperative 6 months. The patient was referred to the physical therapy and rehabilitation department. As a result, an expanded DMCAP flap may cover volar tissue defects up to the distal phalanx. This report may present the first case in which volar finger contracture reconstruction was performed with an expanded first DMCAP flap after an electrical burn in a pediatric patient.

High-voltage electrical injury usually causes severe tissue damage and serious secondary complications. We report a case of treatment of severe high-voltage electrical injury. A series of personalized and effective treatment plans were created through repeated discussions, we successfully handled a series of acute and critical conditions, including severe limb damage, a very large area of full-thickness abdominal wall defect, abdominal viscera (stomach and liver) necrosis, abdominal infection, renal insufficiency, myocardial damage, and malignant arrhythmia (atrial fibrillation). Finally, the wounds were all closed, the functions of the abdominal organs were restored, and the course of the disease was successfully transitioned into the rehabilitation stage. It took a lot of twists and turns but ultimately saved the patient's life. The successful treatment of this patient provides an important reference for similar patients with serious electrical injury in the future.

Objective: To explore the effects of artificial dermis combined with autologous skin in repairing the wounds with exposed bone and/or tendon in fingers of children after electric burns. Methods: A retrospective observational study was conducted. From January 2017 to December 2022, 14 children with bone and/or tendon exposed wounds in fingers after electric burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 9 males and 5 females, aged 2 to 11 years. A total of 38 fingers were affected, with 1 wound per finger. After debridement, artificial dermal coverage combined with vacuum sealing drainage was performed in all the wounds in the first stage, with wound area of 2.0 cm×1.0 cm-4.5 cm×2.5 cm after debridement. The second stage surgery was performed to close the wound with autologous thin intermediate thickness skin graft. Then the children were told to perform functional rehabilitation exercise as early as possible. The survival of autologous skin graft was observed at the 7th day after the second stage surgery. The wound healing time was recorded. After 12 months of follow-up, the Vancouver scar scale was used to evaluate the scar hyperplasia at the skin grafting site of the affected finger; the total action mobility (TAM) of the affected finger joint was measured for evaluating the functional recovery of the affected finger; a self-made efficacy satisfaction rating table was used to investigate the parents' satisfaction with the curative effect of the children. Results: At the 7th day after the second stage surgery, all the children had good survival of autologous skin grafts. The wound healing time was (24.1±2.7) d. After 12 months of follow-up, the scar score at the skin grafting site of the affected finger was 5.2±2.4; the TAM of the affected finger joint was (177±40)°; the functional assessment was good in 12 fingers, medium in 23 fingers, and poor in 3 fingers; the parents' satisfaction with the curative effect of the children in the survey was very satisfied in 10 cases, satisfied in 3 cases, and dissatisfied in 1 case. Conclusions: The combination of artificial dermis and autologous thin intermediate thickness skin graft is an alternative surgical method that can effectively repair the bone and/or tendon exposed wounds in fingers of children after electric burns. After wound healing, the scars are slight, the finger function is well recovered, and the parents of the children are highly satisfied with the curative effect of the children, which is worthy of clinical promotion.

Objective: To explore the selection strategy of pedicled axial flaps for repairing high-voltage electric burn wounds in foot and ankle. Methods: The retrospective observational research method was used. From January 2017 to December 2022, 16 patients with skin and soft tissue defects in foot and ankle after high-voltage electric burns were treated in General Hospital of Eastern Theater Command, including 11 cases of unilateral defect and 5 cases of bilateral defect. All patients were male, aged from 25 to 75 years. After thorough debridement, the area of the defect to be repaired with the flap was 5.0 cm×4.0 cm to 12.0 cm×8.0 cm. Before operation, the color Doppler ultrasound, computed tomography angiography, or digital subtraction angiography was used to fully evaluate the degree of vascular injury in the affected limb and to identify the distribution and traffic anastomosis of vascular network. Pedicled axial flaps with reliable blood supply were used to repair the wounds as soon as possible, and the area of flaps ranged from 3.0 cm×2.0 cm to 13.0 cm×8.0 cm. The wound in the donor area of flaps was repaired with split-thickness skin graft from head or medium-thickness skin graft from thigh. The flap repair of wounds in various areas of the ankle and foot was recorded. The postoperative survivals of the flaps and skin grafts were observed after surgery. The postoperative appearance of flaps and walking function of patients were followed up. At the last follow-up, the foot and ankle function was evaluated and rated using the American Association of Foot and Ankle Surgeons Ankle Posterior Foot Scoring System. Results: Two wounds in toe area were repaired with reverse dorsal pedis flaps, 3 wounds in medial ankle area and 2 wounds in heel area were repaired with medial plantar flaps, 2 wounds in anterior plantar area combined with toe area were repaired with reverse medial plantar flaps, 2 wounds in anterior plantar area combined with toe area and 5 wounds in anterior plantar area were repaired with reverse medial pedis flaps, 1 wound in toe area was combined with proper plantar digital artery flap, 1 dorsal pedis wound and 1 lateral malleolus wound were repaired with lateral supramalleolar perforator flaps, and 1 lateral malleolus wound and 1 dorsal pedis wound were repaired with sural neurovascular flap. One flap had venous reflux disorder after surgery and survived after treatment, while the other flaps and skin grafts survived completely after surgery. During the follow-up of 6 to 24 months after operation, the appearance of the flaps was good, and the walking function of patients was normal. At the last follow-up, the functional score of foot and ankle was 76 to 95, which was evaluated as excellent in 11 cases and good in 5 cases. Conclusions: According to the condition of high-voltage electric burn in foot and ankle, early and thorough debridement, preoperative imaging examination to evaluate blood vessels of the affected limb, and selection of pedicled axial flap with reliable blood supply are good methods for wound repair and related functional reconstruction of high-voltage electric burn in foot and ankle.

Objective: To explore the effects of low position lateral supramalleolar flap carrying periosteum and proximal leg propeller flap in relay repair of electric burn wounds of forefoot. Methods: A retrospective observational study was conducted. From January 2019 to January 2022, 12 patients with electric burn wounds of forefoot meeting the inclusion criteria were admitted to the Sixth Hospital of Shanxi Medical University, including 10 males and 2 females, aged 23-65 years. After debridement, the wound with an area of 6.0 cm×3.0 cm to 15.0 cm×7.0 cm was repaired with the lateral supramalleolar flap carrying part of the periosteum of the distal tibia and fibula with the rotation point moved down to the front of the ankle joint. The area of the cutted flap was 6.5 cm×3.5 cm-15.5 cm×7.5 cm. At the same stage, the donor site wound of lateral supramalleolar flap was repaired with peroneal artery or superficial peroneal artery perforator propeller flap in relay, with the relay flap area of 3.0 cm×1.5 cm-15.0 cm×4.0 cm. After operation, the survival of the lateral supramalleolar flap and relay flap, and the wound healing of the relay flap donor site were observed. During follow-up, the shapes of the lateral supramalleolar flap and its donor site were observed. Results: After operation, one patient developed secondary blisters in the superficial skin distal to the lateral supramalleolar flap, which healed after dressing change, and the lateral supramalleolar flap and relay flaps survived well in the other patients; the donor site wound of the relay flap healed well. During follow-up of 12-18 months, the lateral supramalleolar flaps were in good shape and not bloated, with only linear scar left in the donor site of the flap. Conclusions: The low position lateral supramalleolar flap carrying periosteum can repair electric burn wounds of forefoot with advantages including reliable blood supply, low rotation point, and better repair effects. The use of relay flap to repair the donor site of lateral supramalleolar flap can reduce the damage to the appearance and function of the donor site.

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 â ¡ 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 investigate the clinical effect of the giant deep inferior epigastric artery paraumbilical perforator flap in repairing the circular high-voltage electric burn wounds on the wrist. Methods: A retrospective observational study method was used. From September 2016 to October 2021, thirteen male patients (aged 20-43 years) with annular high voltage (10-100 kV) electrical burns on the wrist were admitted to the Beijing Jishuitan Hospital. At the early stage after injury, the patient's wrist was subjected to incision, tension reduction and debridement, with the wound area after debridement being 27 cm×16 cm-32 cm×19 cm; in 12 patients with vascular injury, the radial or ulnar artery was reconstructed by great saphenous vein transplantation, with the length of 15-25 cm; the wrist wound was repaired by free transplantation of the deep inferior epigastric artery paraumbilical perforator flap (if the wound was giant, the lower abdominal flap carrying other perforators was used), with the area of 30 cm×19 cm-35 cm×20 cm. The donor site was repaired by direct suture+skin grafting or relay flap transplantation. After surgery, the survival of flap in recipient area, as well as survival of the skin or flap in donor site were observed. During follow-up, the appearances of the flap in recipient area and the recovery of hand function, as well as the healing of donor site, occurrence of abdominal wall hernia, and scar in skin graft area were observed. Results: After surgery, all the 13 patients' paraumbilical perforator flaps survived. Among them, 3 patients had subcutaneous fat necrosis at the distal end of the wrist flap, and the wound had mild infection, which healed after re-expansion and dressing change. All the skin grafts in the donor site of 10 patients survived, and the flaps in the donor site of 3 patients survived well. The patients were followed up for 6 months to 3 years. The flaps in recipient area were in good shape, 8 cases had partial recovery of hand function, and 5 cases had loss of finger flexion function; the donor site of abdominal flap healed well with no abdominal hernia occurred, and the skin graft site had no obvious scar hyperplasia and was soft in texture. Conclusions: Early vascular reconstruction after injury, together with free transplantation of the giant deep inferior epigastric artery paraumbilical perforator flap are effective in repairing circular high-voltage electrical burn wounds on the wrist.

Electric burn is a kind of three-dimensional destructive damage. It is necessary to attach great importance to the functional reconstruction and rehabilitation of patients with destructive electric burns. Wound repair and limb salvage are not the end of the treatment of destructive electric burns, but functional rehabilitation and reintegration into society of patients are the goals of treatment. This paper systematically discusses the early wound repair, late functional reconstruction and rehabilitation, limb salvage and amputation, minimized damage of donor area, psychological rehabilitation, and multi-disciplinary cooperation of destructive electric burns. Only by attaching great importance to the functional reconstruction and rehabilitation, and embedding these concepts in people's brains, perfect repair and rehabilitation of destructive electric burns can be realized.

Objective: To investigate the treatment methods of upper limbs with destructive electric burns and its clinical efficacy. Methods: A retrospective observational study was conducted. From July 2014 to December 2020, 20 male patients with destructive electric burns in upper limbs who met the inclusion criteria were admitted to Tongren Hospital of Wuhan University & Wuhan Third Hospital, aged from 21 to 57 years, of whom 7 patients underwent emergency surgery, and a total of 20 affected limbs were treated with limb salvage. The necrotic bone was resected in 5 affected limbs, the residual hand and wrist at the distal end of left affected limb was replanted to the residual end of the right forearm in one patient in a cross heterotopic way, and short reduction and replantation after osteotomy were performed for two affected limbs with distal ulnar and radial necrosis. After thorough debridement, the area of wound proposed to be repaired by tissue flap was from 12 cm×7 cm to 58 cm×13 cm. According to the size and distribution of wound, the wounds of 2 affected limbs were repaired by transplantation of pedicled latissimus dorsi myocutaneous flap and free groin flap with vascular anastomosis. The wounds of the remaining 17 affected limbs were repaired with the transplantation of free latissimus dorsi myocutaneous flap, anterolateral thigh flaps, and paraumbilical perforator flap, with 10 affected limbs with larger wounds being jointly transplanted with the groin flap or the paraumbilical perforator flap on the other side. The total grafted tissue flap area was 20 cm×8 cm to 52 cm×20 cm. During tissue flap transplantation, according to the length of blood vessel defect in the affected limb, the distal artery of the affected limb was bridged with the distal part of flap vascular pedicle, undamaged vein on the affected side, superficial vein of abdominal wall, and great saphenous vein, etc., in 14 affected limbs, and the great saphenous vein was grafted in 3 of them with impeded distal return for recanalization of distal limb veins. The wound in the donor area was repaired by direct suture or grafting with split-thickness scalp. After the wound was basically healed, the functional rehabilitation training was started gradually, and the functional reconstruction and scar rectification surgery were started 3 months after tissue flap transplantation. The survival of tissue flaps/skin grafts, wound healing, limb salvage, and follow-up status after surgery were recorded. At the last follow-up, the function of the successfully salvaged limb was evaluated and scored by the disabilities of the arm, shoulder and hand (DASH) scoring scale. Results: After surgery, the grafted tissue flap in the affected limb and the skin grafts transplanted on the wound at flap donor site survived, and wounds at the recipient and donor sites healed well. Two affected limbs had distal necrosis within 10 days after tissue flap transplantation, and the middle and upper forearms were amputated. The remaining 18 affected limbs were successfully salvaged (including shortened replantation and cross heterotopic replantation). During 6-48 months of follow-up, 5 affected limbs that were successfully salvaged developed aseptic dissolution of residual tendon and bone tissue 3 to 18 months after tissue flap transplantation, which gradually healed after surgical debridement combined with vacuum sealing drainage treatment. At the last follow-up, the stump of two affected limbs healed well after amputation; 18 affected limbs that were successfully salvaged all survived well, of which 8 affected limbs had good recovery of finger flexion and extension function and thumb opponensplasty and could complete daily activities independently, 9 affected limbs regained partial mobility and could complete daily activities such as dressing and eating with the assistance of the opposite upper limb or auxiliary devices, and one affected limb had no function. At the last follow-up, the functional scores of DASH scoring scale of the 18 affected limbs that were successfully salvaged ranged from 30.0 to 100. Conclusions: Timely surgical debridement, proper treatment of the injured bone tissue, effective vascular bridging for reconstruction of the distal artery of the affected limb, and the use of blood-rich tissue flap to repair the wound, combined with early rehabilitation and functional restoration treatment, are beneficial to salvage the upper limb with destructive electric burns and improve the function of the affected limb.

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 medial plantar free flap in reconstructing electric burn wound and scar contracture in the palm. Methods: A retrospective observational study was conducted. From January 2020 to January 2023, 6 patients with electric burn wounds or scar contracture in the palm who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University, including 5 males and 1 female, aged 35 to 55 years. The wound area was 5.0 cm×3.0 cm-8.0 cm×7.0 cm after the debridement of electric burn wounds or resection of scar in the palm. The medial plantar free flap anastomosed with cutaneous nerve was used for wound reconstruction, with flap area of 5.5 cm×3.5 cm-8.5 cm×7.5 cm. The wound in the donor site was repaired with transplantation of abdominal full-thickness skin graft. After surgery, the survival of flaps and skin grafts were observed, the shape and texture of flap and the recovery of donor site of flap were observed, and the holding function of the affected hand was assessed. At the last follow-up, the two-point discrimination distance of flap was measured, the sensory recovery of flap was 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, and the function recovery of flap was evaluated by post-surgery flap function evaluation scale. Results: After surgery, 5 flaps survived well, while the distal part of 1 flap was partially necrotic, which was repaired by medium-thickness skin graft from lateral thigh after debridement. All the skin grafts at the donor sites survived well. During follow-up of 3 to 24 months, the flap was not bloated, the texture and color were good, the match with the surrounding tissue was high, with no obvious scar contracture occurred at the donor site. The affected hand had good holding function. At the last follow-up, the two-point discrimination distance of flap was 6-8 mm, the flap sensation recovery was as follows: 5 flaps recovered to grade S3+, 1 flap recovered to grade S3, and the functional evaluation of flaps was excellent in 5 cases and good in 1 case. The patients basically returned to normal life and work. Conclusions: The medial plantar free flap with cutaneous nerve anastomosis has many advantages, such as high matching degree of appearance, good sensory recovery, and holding function of the affected hand. It is an ideal choice for the reconstruction of the electric burn wound and scar contracture in the palm.

Type III electrical burns on the wrist are characterized by circumferential wounds, three dimensional with sandwich-like necrosis, and progressive blood circulation disturbances. Limb salvage is challenging, and success in meeting this challenge depends on vascular reconstruction and wound coverage. This article is intended for the following purposes: to investigate the principles of wound debridement, the management of involved blood vessels, and the clinical effects of the extended paraumbilical perforator flap pedicled with the inferior epigastric artery for coverage of type III circumferential electrical burns of the wrist. A total of 13 male patients (age, 20 to 43 years; average, 29 years) were enrolled in the study. After early escharotomy, debridement, and vascular reconstruction, all wounds were repaired with the extended paraumbilical perforator flap pedicled with the inferior epigastric artery. Flap survival was achieved in all 13 patients. Subcutaneous liquefaction necrosis and infection beneath the flap occurred in three patients. Radial or ulnar artery reconstruction via the great saphenous vein (GSV) graft was performed in 12 cases. All patients had a mean follow-up of 6 to 36 months, and the flaps demonstrated satisfactory flexibility and texture. Hand function was preserved in eight patients, and no patients developed abdominal hernia. Thorough debridement, early vascular reestablishment, and wound coverage are essential for the overall limb salvage effort for type III circumferential electrical burns of the wrist. The extended paraumbilical perforator flap may provide a new and appropriate option for the primary repair of extensive soft tissue defects.

Soft tissue damage in electric burn injuries is often deep and may expose tendons, bones, or joints in the hand. Here, we present the case of a 76-year-old man treated using perifascial areolar tissue (PAT) transplantation for covering the proximal interphalangeal joint of the middle finger, which had been exposed because of an electric burn. Following ointment therapy, surgery was performed on day 34 postinjury when a deep ulcer with opening of the proximal interphalangeal joint was observed on the dorsum of the right middle finger. After resecting the cartilage of the proximal interphalangeal articular surface, two Kirschner wires were inserted, and arthrodesis was performed. PAT was harvested from the left inguinal region and applied to the joint exposed wound of the middle finger. Full-thickness skin graft was applied over it. Three months after surgery, the preserved middle finger could be used as a functional finger. PAT transplantation does not require microsurgery techniques, is simple and minimally invasive, and has a short treatment period, so it may be an effective option for treating wounds in which exposed ischemic tissue is present. Soft tissue damage in electric burn injuries is often deep and may expose tendons, bones, and joints in the hand, which is the most common affected site. Here, we report a case treated using perifascial areolar tissue (PAT) transplantation for covering the proximal interphalangeal joint of the middle finger, which had been exposed because of an electric burn.

OBJECTIVE: To study the relationship between serum creatine phosphokinase and outcomes of injury in victims with electrical burns. MATERIAL AND METHODS: Among 40 patients with electrical injury, 7 (18%) ones underwent upper limb amputation. There were 37 (92.5%) men and 3 (7.5%) women aged 37 (28; 47) years. We analyzed total serum creatine phosphokinase and MB fraction on the first day in patients with and without amputations. RESULTS: Total serum creatine phosphokinase exceeded the upper reference value in 11 out of 33 patients without amputation and in all 7 patients with limb amputation (p=0.001). Patients with limb amputation had significantly higher total serum creatine phosphokinase and MB fraction (p<0.001 and p=0.030, respectively). Logistic regression equation showed that high total serum creatine phosphokinase significantly influenced amputation rate (p<0.001), as evidenced by odds ratio (42.7, 95% CI 3.5-514.8). ROC analysis revealed the cut-off value of total serum creatine phosphokinase (950 IU/L). Sensitivity was 100% (63; 100), specificity - 94% (86; 94), positive predictive value - 78% (49; 78), negative predictive value - 100% (92; 100). CONCLUSION: Total serum creatine phosphokinase depends only on severity of electrical and flame burns. Serum creatine phosphokinase is a predictor of upper limb amputation in patients with electrical injury. Total serum creatine phosphokinase ≥ 950 IU/L is significant for upper limb amputation (in CK-MB fraction within the reference values).

Electrical trauma is associated with significant morbidity and mortality, which have been reduced by improved medical care, as measured by the length of stay (LOS) as a marker for this population's quality of care. This paper will review the clinical and demographic characteristics, LOS in the hospital, and variables related to patients with electrical burns. A retrospective cohort study was conducted at a specialized burn unit in Southwest Colombia. Five hundred seventy-five electrical burn-related admissions from 2000 to 2016 were reviewed for the LOS and variables including patient-related (age, gender, marital status, education, and occupation), location of the accident (domestic vs labor-related), voltage, direct contact, arc, flash, flame, clinical presentation (burn surface area, depth, single or multiple organ injury, secondary infection, and abnormal labs), and treatment (surgical procedures and intensive care unit [ICU] admission). Univariate and bivariate analysis, with its 95% CI (confidence interval). We also performed a multiple logistic regression. LOS was correlated to males, age greater than 20 years, construction workers, high voltage injuries, severe burns by area and depth, infection, ICU admission, and multiple surgical procedures or extremity amputation. LOS due to electrical injury was observed to be significantly associated with the following variables, carpal tunnel release (OR [odds ratio]= 4.25, 95% CI [confidence interval] 1.70-5.20); amputation (OR = 2.81, 95% CI 1.60-5.10); infection (OR = 2.60, 95% CI 1.30-5.20); site of infection, mainly wound (OR = 1.30, 95% CI 1.10-1.44); associated injury (OR = 1.72, 95% CI 1.00-3.24); work or domestic accident (OR = 1.83, 95% CI 1.00-3.32); aged 20-40 years (OR = 1.41, 95% CI 1.00-2.10); CPK (OR = 1.40, 95% CI 1.00-2.00); and third-degree burns (OR = 1.55, 95% CI 1.00-2.80). Risk factors for LOS secondary to electrical injury should be appropriately addressed. Prevention at high-risk workplaces is imperative. Mitigating the injury with appropriate management of infection and timely surgical interventions play an essential role in the successful treatment of these patients.
