ObjectiveTo summarize the nursing experience of vacuum-assisted closure (VAC) technology for deficiency of skin and soft tissue in "4·20" earthquake damage. MethodsWe used VAC to treat 20 patients suffering from deficiency of skin and soft tissue who were injured in "4·20" earthquake (35 wounds) from April 21st to 28th, 2013; and we observed closely the results of nursing for pain and psychological care. ResultsA total of 35 wounds were all cleaned after 5 to 7 days; 20 wounds were healed after VAC treatment; 15 wounds recovered well by covering autogenous split-thickness skin; 20 patients had stable emotion and all left the hospital with the recovery. ConclusionVAC for deficiency of skin and soft tissue caused by "4·20" earthquake damage may obviously decrease the time of wound healing, relieve the pain caused by changing fresh dressing, and reduce the length of stay in the hospital.
Objective To observe the effectiveness of disposable skin stretch closure in the treatment of wounds with skin and soft tissue defects that were difficult to close. Methods The clinical data of 13 patients with skin and soft tissue defects that were difficult to close treated with disposable skin stretch closure and met the selection criteria between July 2021 and February 2022 were retrospectively reviewed. There were 9 males and 4 females, the age ranged from 15 to 71 years with a mean of 39.8 years. The causes of injury included falling injury in 5 patients, traffic accident injury in 5 patients, and falling from height injury in 3 patients. The causes of skin soft tissue defects included open fractures in 4 patients, wound infection in 4 patients, osteomyelitis in 3 patients, degloving injury in 1 patient, and necrosis of skin graft in 1 patient. The injury was located at calf in 8 patients, calcaneus in 3 patients, pelvis in 1 patient, and plantar in 1 patient. The skin and soft tissue defects ranged from 5.0 cm×2.0 cm to 10.5 cm×6.5 cm. Wound conditions (wound closure and wound healing) and the presence or absence of complications were recorded. Results All 13 patients were followed up 32-225 days with a median of 164 days. The wound closure time ranged from 5 to 14 days, with a mean of 8.8 days. The wound closure speed ranged from 0.7 to 13.7 cm2/day, with a mean of 3.6 cm2/day. All wounds healed at grade A, and no complication such as skin edge injury, wound necrosis, infection, dehiscence, and edema occurred. No patient complained of pain or discomfort, and no obvious scarring was found during follow-up. The wound healing time ranged from 17 to 28 days, with a mean of 21.7 days. One of them was transferred to other department due to lung cancer condition changes after using disposable skin stretch closure, and the wound had directly healed without suturing at 17 days after operation. Conclusion The effectiveness of disposable skin stretch closure in the treatment of wounds with skin and soft tissue defects that were difficult to close was exact, with short wound closure time, few complications, and easy operation.
ObjectiveTo investigate the treatment outcome of applying venous Flow-through flap in the replantation of severed finger with circularity soft tissue defect and vascular defect. MethodsBetween January 2010 and December 2012,11 cases (11 fingers) of severed finger with circularity soft tissue defect and vascular defect underwent replantation with venous Flow-through flaps.There were 8 males and 3 females,aged 18-42 years (mean,24.6 years).The cause of injury was squeeze injury in 6 cases,crush injury in 3 cases,and strangulation in 2 cases.Combined injuries included nerve defect in 3 cases (1.0,2.0,and 3.5 cm in length),and tendon defect in 2 cases (2.0 and 6.5 cm in length); cyclic skin and soft tissue defect was 3.0-4.5 cm in width,was 1/2-1 finger circumference in length,and was 2.0 cm×1.0 cm to 7.0 cm×4.5 cm in size.Six cases had complete circular defect (both finger artery and vein defects),and 5 cases had incomplete circular defect (only finger artery defect),and vascular defect was 1.0-4.5 cm in length.The time from injury to operation was 1.5-4.5 hours. ResultsVenous crisis occurred in 1 case at 2 days after operation,was cured after vein graft; flap edge necrosis was observed in 2 cases and was cured after dressing change and skin grafting respectively; flap edema and blister occurred in 2 cases and relieved spontaneously.The other 6 flaps and replanted fingers survived completely,with primary healing of incision.Ten cases were followed up 12-18 months (mean,15.5 months).Only a linear scar was seen at the donor sites,with no functional limitation.The flaps had similar color and texture to adjacent skin.The two-point discrimination was 6.5-13.0 mm (mean,8.6 mm).According to replanted finger function scoring system of Society of Hand Surgery of Chinese Medical Association,the results were excellent in 6 cases,good in 3 cases,and poor in 1 case at last follow-up,and the excellent and good rate was 90%. ConclusionVenous Flow-through flap can repair both vascular defect and soft tissue defect,so it has good outcome in increasing the survival rate of replanted finger for severed finger replantation with circularity soft tissue defect and vascular defect.
Objective To investigate the effectiveness of tissue transplantation combined with bone transmission in treatment of large defects of tibial bone and soft tissue. Methods Between February 2006 and February 2011, 15 cases of traumatic tibia bone and soft tissue defects were treated. There were 12 males and 3 females, aged from 16 to 54 years (mean, 32 years). After internal and external fixations of fracture, 11 patients with open fracture (Gustilo type III) had skin necrosis, bone exposure, and infection; after open reduction and internal fixation, 2 patients with closed fracture had skin necrosis and infection; and after limb replantation, 2 patients had skin necrosis and bone exposure. The area of soft tissue defect ranged from 5 cm × 5 cm to 22 cm × 17 cm. Eight cases had limb shortening with an average of 3.5 cm (range, 2-5 cm) and angular deformity. The lenghth of bone defect ranged from 4 to 18 cm (mean, 8 cm). The flap transplantation and skin graft were used in 9 and 6 cases, respectively; bone transmission and limb lengthening orthomorphia were performed in all cases at 3 months after wound healing; of them, 2 cases received double osteotomy bone transmission, and 14 cases received autologous bone graft and reset after apposition of fracture ends. Results All flaps and skin grafts survived; the wound healed at 3.5 months on average (range, 3 weeks-18 months). The length of bone lengthening was 6-22 cm (mean, 8 cm). The time of bone healing and removal of external fixation was 9.5-39.0 months (mean, 15 months). The healing index was 40-65 days/cm (mean, 55 days/cm). All patients were followed up 1-5 years (mean, 4 years). The wounds of all the cases healed well without infection or ulceration. The functions of weight-bearing and walking were recovered; 6 cases had normal gait and 9 cases had claudication. The knee range of motion was 0° in extention, 120-160° in flexion (mean, 150°). According to the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system for ankle function, the results were excellent in 7 cases, good in 4 cases, and fair in 4 cases, with an excellent and good rate of 73.3%. Conclusion Tissue transplantation combined with bone transmission is an effective method to treat large defects of soft tissue and tibial bone, which can increase strength of bone connection and reduce damage to the donor site.
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.
