ObjectiveTo introduce the surgical method and effectiveness of repairing skin and soft tissue defect in the palm or dorsum of the hand and forearm with epigastric bilobed flap. MethodsBetween October 2010 and December 2013, 4 male patients with skin and soft tissue defect in the palm or dorsum of the hand and forearm were treated, aged from 36 to 62 years. Of them, 3 cases had degloving injury caused by machines and 1 case had necrosis of fingers and skin after surgery of crush injury. The time from injury to hospitalization was from 3 hours to 15 days. Among the 4 cases, the size of palmar defect was 7 cm×4 cm to 16 cm×6 cm, and the size of dorsal defect was 10 cm×7 cm to 20 cm×10 cm. The epigastric bilobed flap was designed based on the axial vessel which was formed by inferior epigastric artery, superior epigastric artery, and intercostals arteries. The size of flap ranged from 12 cm×4 cm to 18 cm×6 cm in the vertical direction, 15 cm×8 cm to 22 cm×11 cm in the oblique direction. The donor site was directly closed. The pedicles were cut at 22 to 24 days after repairing operation. ResultsAll the flaps survived well with the wound healing by first intention. Four patients were followed up 3 months to 1 year and 2 months. The other flaps had good appearance and texture except 1 bulky flap. The flap sensation basically restored to S2-S3. The function of the hands recovered well. ConclusionSkin and soft tissue defect in the palm or dorsum of the hand and forearm can be repaired with the epigastric bilobed flap, because it has such advantages as big dermatomic area and adequate blood supply. Besides, the operation is practical, safe, and simple.
Objective?To introduce a new method of flap design and to investigate the feasibility of the clinical application.?Methods?Between April 2006 and November 2009, 89 patients with skin and soft tissue defects were treated. There were 47 males and 42 females with an average age of 36 years (range, 16-67 years). The injuries were caused by machine crush (38 cases), electric saw (16 cases), electricity (8 cases), traffic accident (18 cases), rolling machine (3 cases), and crash of heavy object (6 cases). The locations were forearm in 4 cases, palm in 23 cases, finger in 41 cases, lower leg in 7 cases, and dorsum of foot in 14 cases. All the cases complicated by exposure of tendons or bones. The time from injury to hospitalization was 30 minutes to 5 days (mean, 3 hours). The areas of skin and soft tissue defect ranged from 2.0 cm × 1.5 cm to 26.0 cm × 18.0cm. The wounds were repaired with the pedicle flaps in 72 cases and the free flaps in 17 cases. All the flaps were designed with eight-point-location method. A trapezoid was made in the raw surface and the four vertexes of the trapezoid were on the edge of the raw surface. The exterior points of the heights of arciforms were made on the edge of the raw surface too. The eight points were the labelling points. The top width, the bottom width, the height of the trapezoid, and the heights of the arciforms could be measured. The above numerus were expanded 5%-10%. The expanded numerus were the corresponding numerus of the skin flap. The size of flaps ranged from 2.2 cm × 1.7 cm to 28.5 cm × 19.5cm. The donor sites were closed directly in 17 cases, and repaired with skin grafts in 72 cases.?Results?All the flaps were successfully dissected according to flap design. When the flaps were transplanted to the wounds, tension of the flaps was appropriate. All the flaps and skin grafts survived. The wounds and incisions at donor sites healed by first intention. Eighty-nine patients were followed up 6 to 26 months (mean, 20 months). The texture, appearance, flexibility, and function of the flaps were satisfactory, and no complication occurred. The sensory restoration of the pedicle flaps were graded as S3-S4.?Conclusion?It is an ideal and simple method to design flap using eight-point-location method. The flaps are precise in the figure and area.
Objective To investigate the operative procedure and the cl inical results of reverse lateral tarsal artery flap in treating forefoot skin and soft tissue defect. Methods From August 2007 to April 2009, 11 patients with forefoot skin and soft tissue defect were treated with reverse lateral tarsal artery flaps, including 7 males and 4 females aged from 16 to 60 years(36 years on average). Of 11 cases, defects were caused by crash in 5 cases, by grind contusion in 3 cases and the course disease was 4-12 hours; by tumor extended resection in 3 cases and the disease course was 3-12 months. There were 5 wounds on the dorsum of first metatarsophalangeal joint, 2 on the dorsum of the first toes, and 4 on the dorsum of distal part of metatarsal bones. The area of defect ranged from 4 cm × 2 cm to 6 cm × 5 cm. There were 6 cases of tendon exposure, 4 cases of tendon defect with bone exposure, and 1 case of tendon defect with open dislocation of metatarsophalangeal joint. The flap was designed with dorsal artery of foot as its pedicle. The plantar perforating branch was designed as its rotating point. And the flaps were transferred retrogradely to repair the forefoot wounds. The flap area ranged from 4.5 cm × 2.5 cm to 6.5 cm × 4.5 cm. The lateral dorsal nerve of foot was anastomosed with the nerve in wound area in 7 cases. Donor site was covered by full thickness skin graft. Results Partial necrosis occurred and was cured by dressing change, followed by skin graft in 2 cases. The flaps survived and primary heal ing was achieved in the other 9 cases. All the skin grafts of donor site survived and primary heal ing wasachieved after operation. All the patients were followed up for 6 months to 2 years, averaged 13 months. The texture and color of the flap were similar to skin at the recipient site. All patients returned to normal in walking and running and no ulceration occurred. The two point discrimination was 5-12 mm 6 months after operation in 7 patients who received nerve anastomosis, while only protective sensation recovered partly in the other 4 patients whose cutaneous nerve were not anastomosed. Conclusion Reverse lateral tarsal artery flap has the perfect shape and its blood vessel is constant. The blood pedicle is thick and long enough when transferred retrogradely. The flap is a good choice in the treatment of forefoot skin and soft tissue defect.
OBJECTIVE: To evaluate the application of skin and soft tissue expansion in the treatment of deformity due to extensive severe burn injury and repair of severe deep electrical burned scalp and skull with fresh wound. METHODS: From 1988, 83 cases of application of skin and soft tissue expansion were reported. In those patients with deformity due to severe burn of large area and with whole nasal defect, soft tissue expander was used under the forehead skin graft and venter frontalis, followed by reconstruction of nose with the expanded vascularized skin flap and carved cartilago costalis as nasal frame. In patients of severe deep electrical burned scalp and skull with fresh wound, skin and soft tissue expansion were used to repair the wound simultaneously with scalp burn alopecia, anesthetics and antibiotics injected into the extracapsular space of the expander in case of pain and infection. RESULTS: All of the cases were successfully treated with little pain and minimized infection. CONCLUSION: Skin and soft tissue expansion in a safe and reliable measure in the treatment of deformity due to extensive severe burn injury and repair of severe deep electrical burned scalp and skull with fresh wound.
ObjectiveTo investigate the effectiveness of V-Y advanced medial gastrocnemius muscle flap to repair soft tissue defects in the middle and lower segments of the anterior tibia. MethodsBetween March 2008 and March 2014, 8 patients with skin and soft tissue defects of the anterior tibia were treated, including 6 males and 2 females with an average age of 36.2 years (range, 28-47 years). The soft tissue defects located at the left leg in 5 cases and at the right leg in 3 cases. The causes included traffic accident injury in 6 cases, and heavy pound injury in 2 cases. Three cases had simple soft tissue defects, and the disease course was 5 hours, 6 days, and 14 days, respectively. Five cases had soft tissue defects and fractures, including 1 case of Pilon fracture, and 4 cases of middle and distal tibial fracture; open reduction and internal fixation were performed in 3 cases, the implementation of external fixation in 2 cases; 1 case had chronic osteomyelitis at 11 months after operation, and 4 cases had skin necrosis and wound infection at 1 to 2 weeks after operation; the duration was 1-12 months (mean, 3.4 months). The skin and soft tissue defect area was 5.2 cm×2.5 cm to 13.0 cm×5.5 cm. Debridement was given, and vacuum sealing drainage was used in 6 cases, and then V-Y advancement of medial gastrocnemius muscle flap was used to cover the wound. Because of light wound contamination, the wound was repaired by the flap after emergency debridement in 1 case; 1 patient with osteomyelitis underwent flap repair at immediate after sensitive antibiotics use and debridement. The size of medial gastrocnemius muscle flaps ranged from 15 cm×6 cm to 26 cm×15 cm. The donor site was sutured in 3 cases or repaired with skin graft in 5 cases. ResultsOne case had tension blisters in the distal flap, which was cured after symptomatic treatment. The flap and skin graft survived, and primary healing was obtained in the other cases. Seven patients were followed up 6-18 months (mean, 9 months). The texture and appearance of the flaps were satisfactory. At 6 months after operation, two-point discrimination ranged from 12 to 18 mm (mean, 16 mm). The plantar flexion was weaker than that of normal side, but the patients could normally walk and had normal gait. ConclusionThe V-Y advancement of medial gastrocnemius muscle flap is recommendable to repair soft tissue defects in the middle and lower segments of the anterior tibia for the advantages of reliable blood supply, simple operation, high survival rate of the flap, and satisfactory appearance.
ObjectiveTo investigate the clinical value of pedicled latissimus dorsi Kiss flap in repairing chest wall large skin defect after tumor operation. MethodsA retrospective analysis was made on the clinical data from 15 cases of chest wall tumors treated between December 2010 and December 2015. There were 2 males and 13 females with an average age of 51.8 years (range, 43-60 years); there were 11 cases of locally advanced breast cancer, 3 cases of fibrosarcoma in chest wall, and 1 case of chest wall radiation ulcer with a median disease duration of 24.1 months (range, 6 months to 8 years). The area of skin defects was 17 cm×12 cm to 20 cm×18 cm after primary tumor resection; the pedicled latissimus dorsi Kiss flap was designed to repair wounds. The flap was a two-lobed flap at a certain angle on the surface of latissimus dorsi based on the thoracodorsal artery, with a size of 17 cm×6 cm to 20 cm×9 cm for each lobe. The donor site was sutured directly. ResultsFourteen flaps survived with primary healing of wound; delayed healing was observed in 1 flap because of distal necrosis; and healing by first intention was obtained at the donor sites. The follow-up time was from 6 months to 3 years (mean, 21.6 months). The flap had good appearance with no bloated pedicle. The shoulder joint activities were normal. No local recurrence occurred, but distant metastasis in 2 cases. No obvious scar was found at donor sites. ConclusionThe application of pedicled latissimus dorsi Kiss flap to repair chest wall skin defects after tumor resection has important clinical value, because of the advatages of simple operation, minor donor site damage and rapid postoperative recovery, especially for late stage cancer patients.
ObjectiveTo summarize the effectiveness of delayed skin-stretching device in treatment of skin and soft tissue defects.MethodsBetween December 2014 and December 2016, 10 cases of skin and soft tissue defects were treated with delayed skin-stretching device. There were 6 males and 4 females with an average age of 53 years (range, 42-64 years). The skin and soft tissue defects were caused by acute trauma in 6 cases. The incision could not be closed directly after making incisions because of osseous fascia syndrome in 3 cases. The skin soft tissue defect caused after huge carbuncle incision and drainage in 1 case. The defect located at thigh in 4 cases, lower leg in 3 cases, upper arm in 2 cases, back in 1 case. The defect area ranged from 10 cm×4 cm to 22 cm×12 cm. Pinch test was performed on the wound margin, which confirmed that the wound could not be closed directly.ResultsTension blisters were found in 3 cases during traction, and no complications such as impaired blood circulation or skin necrosis occurred in all cases. Skin defects closed directly after continuously stretching for 7-18 days. No skin graft or free flap repair was performed in all patients. The wound healed well after operation. All the 10 patients were followed up 5-8 months (mean, 6.5 months). There was no necrosis around the wound margin and the scar was linear. The sensation and function were not affected.ConclusionDelayed skin-stretching device is an effective method to treat skin and soft tissue defects, which has the advantages of simple operation, lower risk of operation, less complications, and reliable effectiveness.
ObjectiveTo explore the epidemiological characteristics and analyze the related diagnosis and treatment information of wound outpatient cases in a tertiay hospital in Leshan City.MethodsThe data of cases admitted to the wound clinic in a tertiary hospital of Leshan City between January 1st, 2017 and December 31st, 2019 were retrospectively collected. The SPSS software was used for statistical analyses in terms of basic patient information, wound type and dressing use, number of visits and expenses.ResultsA total of 10 880 cases were enrolled. The average age of the patients treated was (45.23±13.45) years old. Patients from the Central District, where the hospital was located in, accounted for the highest proportion (38.63%). The proportion of acute skin and soft tissue injuries was higher than that of chronic skin and soft tissue injuries (62.51% vs. 37.49%). According to the proportions from high to low, the top three chronic skin and soft tissue injuries were postoperative refractory wounds (19.63%), skin and soft tissue infections (3.90%), and stoma complications (3.04%), respectively. A total of 22 937 functional wound dressings were used, of which non-woven outer dressings accounted for 47.52%. Patients with acute skin and soft tissue injuries had a higher healing rate compared with those with chronic skin and soft tissue injuries (96.65% vs. 43.03%, P<0.05). The type of skin and soft tissue injuries with the most visits was cancerous wound [the median (lower quartile, upper quartile) was 68 (35, 121) visits], and the one with the least visits was acute skin and soft tissue injuries [the median (lower quartile, upper quartile) was 2 (1, 7) visits].ConclusionsAs the distance between residence and hospital grows, the number of patients decreases, suggesting that the specialized nursing assistance has achieved initial results in remote areas, but the task of assistance in surrounding areas is still heavy. The type of skin and soft tissue injuries is changing under the concept of enhanced recovery after surgery, and wound care plays an important role in the recovery of patients after surgery. The concept of wet healing and new dressings to promote wound healing are widely used, but still need to be further popularized among patients and medical staff. For chronic wounds that are more expensive to treat, it is necessary to formulate comprehensive treatment plans such as wound treatment, psychological support, and systemic nutrition to promote healing.
Objective To investigate the effectiveness of the second dorsal metacarpal artery fascial vascular pedicle retrograde island flap relaying the dorsal island flap of the index finger in repairing skin and soft tissue defects of the thumb. Methods The clinical data of 8 patients with skin and soft tissue defects of thumb between October 2019 and January 2021 were retrospectively analyzed. There were 3 males and 5 females with an average age of 35 years (range, 18-52 years). The causes of injury included machine injury in 2 cases, crush injury in 3 cases, and cutting injury in 3 cases. There were 2 cases of dorsal defect of the proximal part, 1 dorsal defect of the distal part, and 5 instances of the distal part defect. The skin and soft tissue defects ranged from 1.7 cm×1.4 cm to 3.0 cm×2.5 cm. The time from injury to flap repair was 7-21 days, with an average of 14 days. Firstly, the dorsal island flap of the index finger (dorsal side of the proximal part of the index finger) was used to repair the defect of the thumb. Then the second dorsal metacarpal artery fascia vascular pedicle retrograde island flap (near the radial side of the back of the hand) was used to repair the dorsal defect of the index finger; the donor site was sutured directly. ResultsVascular crisis of the flap occurred in 1 case within 48 hours after operation, and the flap was bloated and bruised in 1 case due to excessive suture tension, and all the flaps survived after symptomatic treatment; partial skin margin of the flap was necrotic in 1 case after operation, and the incision healed after dressing change; the other 5 flaps survived, and all the wounds in the donor and recipient sites healed by first intention. All the 8 patients were followed up 3-10 months, with an average of 6 months. One patient had mild scar; the other patients had no significant difference in the color of the flap and the surrounding skin, no adhesion of tendons, and little interference of index finger function, and there was no obvious pain and dysfunction in the donor and recipient sites of the flap. At last follow-up, the extension-flexion range of motion of the metacarpophalangeal joint of the thumb was 0°-55°, and that of the interphalangeal joint was 0°-75°; the extension-flexion range of motion of the metacarpophalangeal joint of the index finger was 0°-82°, that of the proximal interphalangeal joints was 0°-90°, and that of the distal interphalangeral joints was 0°-65°. Conclusion The application of the second dorsal metacarpal artery fascial vascular pedicle retrograde island flap relaying the dorsal island flap of the index finger to repair skin and soft tissue defect wounds of thumb is a feasible treatment with reliable blood supply, less postoperative complications, no need for skin grafting, less interference to the function of the index finger, and satisfactory wound repair effect.
