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.
Objective To investigate the therapeutic effect of medial sural artery perforator flap in the repair of small and medium size skin and soft tissue defects in the ipsilateral lower extremities. Methods The clinical data of patients with small and medium area skin and soft tissue defects of lower limbs admitted to Restorative and Reconstructive Department, NO.1 Orthopedics Hospital of Chengdu between September 2021 and January 2023 was retrospectively analyzed. Basic information of patients was collected. The anatomical characteristics, application methods, and clinical results of the flap were recorded after operation, and the comprehensive efficacy evaluation table of the flap was used to evaluate the clinical efficacy at the last follow-up. Results A total of 13 patients were included. There were 12 males and 1 female. A total of 19 perforating branches of medial sural artery were found in the 13 cases, with an average of 1.46 perforating branches. The incision range of the flap was 5.5 cm×3.5 cm−13.5 cm×5.0 cm. Anterograde pedicle metastasis occurred in 3 cases and free transplantation occurred in 10 cases; mosaic flaps were used in 5 cases, lobed flaps in 1 case, and conventional perforator flaps in the remaining 7 cases. All the flaps survived successfully. All the 13 patients were followed up for 4-15 months, with an average of (10.38±3.64) months. The comprehensive score of flap efficacy was 77-92 points, with an average of (86.76±4.45) points. Among them, 5 cases were excellent, 8 cases were good, and the excellent and good rate was 100%. Conclusion The multifunctional features and flexible use of medial sural artery perforator flap increase the repair strategy of small and medium-sized wounds of the ipsilateral lower limbs, and can obtain better aesthetic repair results.
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.
