METHODS: In 1994 to 1997, 47 cases with multiple fingers degloving injury were sutured by two reverse "s"-type skin flaps on abdominal flank. RESULTS: The skin flaps in 46 cases survived and the wounds obtained primary heal. CONCLUSION: The application of abdominal flank "s"-type skin flap is reliable and convenient in the treatment of multiple fingers degloving injury.
Objective To estimate clinical effect ofspin iliac deep vascular pedicled periosteum flap in repairing traumatic femoral neck of theca inside fracture in young and middleaged. Methods From April 1993 to September 2001, 12 cases of traumatic femoral neck fracture were given diaplastic operation with fixation of 3 centre hollow pressed bolt and were conducted under os traction bed and "C" arm X-ray machine. Spin iliac deep vascular pedicled periosteum flap wasstripped off, and transferred to the front of femoral neck fundus，then transplanted to the narrow inside of fracture through outer open door of articular capsule.Results All patients were followed up for 17 years. All fracture healedwithout femoral head necrosis, but mild arthritis appeared in 7 cases.Conclusion Vascular pedicled periosteum flap transfer of young and middle-aged femoral neck fracture, by decompression of femoral neck and reconstruction of blood circulation, can promote the fracture healing and decrease the wound and blood circulation destroy.
Rectus femoris muscle of the lower abdomen was used as myocutaneous flap in the reconstruction of the breast in 4 patients, of which, in 2 cases the reconstruction was carried out immediately following the radical mastectomy for breast cancer by using trancfer of the pedicled myocutaneous flap, and in the other two cases, the vascularized free myocutaneous flap was used 2 months and 5 years after the radical mastectomy, respectively. The vascularized free myocutaneous flaps were survived, however, in the pedicled myocutaneous flap group, the fat of the flaps had liquefaction 23 weeks after operation. The latter were healed after repeated dressings. The external appearance of the 4 reconstructed breasts lookedsattisfactory. The patients wete follwed up for 10 to 18 months, 2 patients hadno ill effects, while the 2 pedicled myocutaneous flaps, in which 1 patient hadbulging of the weakened abdominal wall, and the other had lost from follow up.
【Abstract】 Objective To explore the effectiveness of reducing tension method on the survival and appearance of distally-based pedicle flap. Methods Between October 2009 and February 2011, 27 cases of defect of extremity skin and soft tissue were repaired with distally-based pedicle flap through reducing tension flap method. There were 19 males and 8 females with an average age of 31.5 years (range, 17-58 years). Defects were caused by traffic accident in 14 cases, by machine in 9 cases, by surgical infection in 3 cases, and by tumor excision in 1 case. The locations were the distal tibia in 7 cases, the ankle-joint in 12 cases, the foot in 5 cases, the palm in 2 cases, and the dorsum of hand in 1 case. The time from injury to hospitalization was 1-19 hours with an average of 10 hours. The size of defect ranged from 5.2 cm × 3.8 cm to 14.0 cm × 5.8 cm. The size of distally-based pedicle flap ranged from 5.5 cm × 4.5 cm to 14.5 c m × 6.5 cm. The donor sites were sutured directly in 6 cases and were repaired with skin grafting in 21 cases. Results All reducing tension flaps survived. Partial necrosis occurred in the distally-based pedicle flap in 3 cases at 7 days after operation, which was cured after dressing change and skin grafting in 1 case, after excision of necrosis skin edge and direct suture in 2 cases. The other flaps survived and wounds achieved primary healing. The incisions at donor sites healed by first intention and skin grafting survived. Twenty-six cases were followed up 6-12 months (mean, 7.5 months). The appearance and texture of the flaps were good. Conclusion Pedicle reducing tension flap could promote the survival and the appearance of distally-based pedicle flap.
OBJECTIVE: To explore the anatomic feature and clinical application of the bone (periosteum) flap pedicled with upper muscular branches of lateral femoral muscle. METHODS: The anatomic features and distribution of upper muscular branches of lateral femoral muscle were observed in the lower extremities of 40 adult cadavers. From February 1989 to February 1999, 7 cases with bone defect or nonunion of upper part of femur were treated with transfer of bone (periosteum) flap pedicled with upper muscular branches of lateral femoral muscle. RESULTS: The upper muscular branches of lateral femoral muscle originated from the transversal branch of lateral circumflex femoral artery. The musculoperiosteal branch and periosteal branch were originated at 16.8 +/- 3.0 cm below the greater trochanter. The diameter and length of musculoperiosteal branch were 1.4 to 1.7 mm and 2.7 to 5.6 cm, those of the periosteal branch were 0.4 to 0.6 mm and 1.2 to 1.5 cm respectively. Bone union achieved in 10 to 18 weeks after operation in all 7 cases after 18 to 42 months follow-up. The motion of hip joint reached 180 degrees in 4 cases, 120 degrees in 2 cases and 65 degrees in 1 case. The donor area recovered well. CONCLUSION: The bone (periosteum) flap pedicled with upper muscular branches of lateral femoral muscle is an effective alternative for repairing the bone defect or nonunion of the upper or middle part of femur.
Objective To investigate the effectiveness of transvertebral space and under the pedicle osteotomy for thoracolumbar kyphosis caused by old osteoporotic vertebral compression fracture (OVCF). Methods The clinical data of 11 patients with thoracolumbar kyphosis caused by old OVCF treated by transvertebral space and under the pedicle osteotomy between January 2016 and December 2020 were retrospectively analyzed. There were 2 males and 9 females, with an average age of 61.3 years (range, 50-77 years) and with a median disease duration of 8 years (range, 6 months to 50 years). Fracture reasons: 9 cases had a clear history of trauma, and 2 cases had no obvious incentive. A total of 11 vertebrae was involved in fracture, including T12 in 3, L1 in 7, L2 in 1. The operation time, intraoperative blood loss, postoperative drainage volume, and complications were recorded. Full-length X-ray films of spine and local X-ray films of the operation area were examined before operation, at 7 days after operation, and at last follow-up. The Cobb angle of thoracolumbar kyphosis was measured, and the correction rate was calculated. The visual analogue scale (VAS) score and Oswestry disability index (ODI) were recorded to assess patients’ pain and functional improvement before operation, at 1 month after operation, and at last follow-up. Results All operations were successfully completed. The average operation time was 188.6 minutes (range, 140-215 minutes); the average intraoperative blood loss was 268.2 mL (range, 100-500 mL); the average postoperative drainage volume was 615.5 mL (range, 160-1 500 mL). One patient developed bilateral thigh rebound pain after operation, which relieved after symptomatic treatment of nutritional nerve and acesodyne. All patients were followed up 14.7 months on average (range, 6-56 months). At last follow-up, osseous fusion was observed in all patients, and no fracture, loose, or displacement of internal fixator was observed on imaging. At 7 days after operation and at last follow-up, the Cobb angle of thoracolumbar kyphosis significantly improved when compared with preoperative one (P<0.05), and there was no significant difference between at 7 days after operation and at last follow-up (P>0.05); the correction rates of Cobb angle at 7 days after operation and at last follow-up were 68.0%±9.8% and 60.3%±11.9%, respectively. At 1 month after operation and at last follow-up, the VAS score and ODI significantly improved when compared with preoperative ones, and further improved at last follow-up when compared with those at 1 month after operation, all showing significant differences (P<0.05). ConclusionTransvertebral space and under the pedicle osteotomy is an effective way to treat thoracolumbar kyphosis caused by old OVCF with less trauma, shorter operation time, and less intraoperative blood loss. Patients can obtain good orthopedic results and quality of life.
OBJECTIVE In order to increase the survival area of pedicled fasciocutaneous flap, a multiple pedicled blocking randomized fasciocutaneous flap was designed. METHODS From January 1991 to September 1998, this technique was used to repair 33 cases, including 27 males and 6 females and the ages ranged from 6 to 58 years. All of the patients were suffered from traffic accidents. In these cases, 22 cases had skin defects of legs and feet with bone, nerve and tendon exposed, 5 cases had osteomyelitis as well as internal fixaters exposed and the other 6 had deformity from scar. The size of the flap was 25.0 cm x 13.0 cm x 2.4 cm at its maximum and 6.0 cm x 3.5 cm x 1.5 cm at its minimum. Based on the traditional blocking flap, according to the severity of the wound and conditions of the neighboring tissues, a flap having 2 to 4 orthogonal pedicles with a width of 1.5 to 3.0 cm was designed. The medical-graded stainless steel sheet was implanted below the deep fascia, and after blocking for 3 to 6 days, the side pedicles were divided. 6 to 14 days later, one of the two remaining pedicles was divided and was transferred to repair the defect. RESULTS 31 cases were followed up for 6 months to 5 years without any trouble of the joints. The flap had a good external appearance and was high pressure-resistant. CONCLUSION The multiple pedicled blocking randomized fasciocutaneous flap increased the size of the flap and the length to width ratio. It had the following advantages: manage at will, high resistance to infection and a large survival area of flap.
Abstract From March, 1987 through May, 1996, a total of 13 cases of severe deep burn and bone defect of hand and wrist were treated by groin skin and iliac bone composite graft with vascular pedicle and had resulted in satisfactory result. The operation was relatively simple. Because thecomposite graft carried its own blood supply in the pedicle, it was not necessary to revascularize the composite graft by anastomosis of blood vessel during operation. Owing to the presence of abundant vascular supply of the iliac bone, the antiinfection potency was high, so its application was suitable for those conditions such as fresh severe deep burn with infection and bone defect. As a result, this technique gave the best chance to save the limb from amputation, and the duration required for treatment could be markedly shortened. This method provided the possibility to solve effectively the difficult problem dealing with the treatment of severe deep burn with infection and bone defect of the hand and wrist.
ObjectiveTo explore the effectiveness of dual-pedicle abdominal flap for unilateral breast reconstruction.MethodsBetween March 2014 and March 2018, a clinical data of 19 female patients underwent dual-pedicle abdominal flap reconstruction because of unilateral mastectomy defect was reviewed retrospectively. The median age was 45 years (range, 32-51 years), including 3 immediate breast reconstruction and 16 delayed breast reconstruction, and left side in 7 cases and right side in 12 cases. Unilateral breast reconstruction were performed for 8 patients with unilateral pedicle transverse rectus abdominis musculocutaneous (TRAM) flap and contralateral free TRAM flap, for 3 patients with pedicle TRAM flap and contralateral deep inferior epigastric perforator (DIEP) flap, for 7 patients with bilateral DIEP flaps, for 1 patient with free muscle-sparing TRAM flap and contralateral DIEP flap. The size of abdominal flap ranged from 24 cm×7 cm to 43 cm×13 cm. The donor sites were closed directly.ResultsVascular crisis ocuurred in 1 flap and relieved after surgical exploration. The other flaps survived. Poor wound healing in abdominal incision occurred in 1 patient and was successfully treated with debridement. The other donor sites healed without any other complication. The patients were followed up with a median period of 12 months (range, 4-42 months). Four patients received reparative operation of their reconstructive breast, and 2 patients received mamopexy of the contralateral breast due to mastoptosis. The abdominal BREAST-Q score was 84.1±11.7, chest score was 86.5±8.9, and breast score was 67.6±16.4 at last follow-up.ConclusionThe dual-pedicle abdominal flap for unilateral breast reconstruction provides adequate soft tissue volume and good blood supply. It is a reliable and effective breast reconstructive method for patients who need large tissue volume to make symmetric with the contralateral breast, or slim patients with few tissue in the donor site, or patients with scars in the donor site, especially vertical abdominal scars.
ObjectiveTo evaluate the feasibility and the effectiveness of minimally invasive passage in posterior laminotomy decompression and intervertebral bone grafting combined with percutaneous pedicle screw fixation for the treatment of Denis type B thoracolumbar burst fractures. MethodsBetween January 2013 and March 2015, 53 patients with Denis type B thoracolumbar burst fractures were treated by minimally invasive passage in posterior laminotomy decompression and intervertebral bone grafting combined with percutaneous pedicle screw fixation. There were 37 males and 16 females with a mean age of 43 years (range, 16-57 years). The causes included falling injury from height in 23 cases, traffic accident injury in 15 cases, heavy pound injury in 7 cases, and falling injury in 8 cases. The time between injury and operation was 7 hours to 12 days (mean, 6.7 days). The involved segments included T11 in 2 cases, T12 in 7 cases, L1 in 20 cases, L2 in 18 cases, and L3 in 6 cases; based on the neurological classification of spinal cord injury by American Spinal Injury Association (ASIA), 3 cases were rated as grade A, 5 cases as grade B, 12 cases as grade C, 24 cases as grade D, and 9 cases as grade E. The operation time, bleeding volume, and postoperative drainage were recorded; postoperative visual analogue scale (VAS) was used for pain evaluation, and ASIA for neurological function assessment; CT and X-ray films were taken to observe fracture healing, bone fusion, and grafted bone absorption; The vertebral canal patency rate was calculated; the relative height of fractured vertebrae and Cobb angle were measured. ResultsThe operation was successfully completed in all patients; the average operation time was 150 minutes (range, 90-240 minutes); the average bleeding volume was 350 mL (range, 50-500 mL); the average postoperative drainage was 80 mL (range, 20-150 mL); and the average VAS score was 2.3 (range, 1.5-4.7) at 3 days after operation. The incisions healed primarily. All the patients were followed up 12-19 months (mean, 15 months). All fractures healed at 3-9 months (mean, 6 months). No complications of broken nails, broken rod, and screw loosening occurred. At last follow-up, the vertebral canal patency rate was significantly improved when compared with preoperative value (t=27.395, P=0.000). The Cobb angle, and the anterior and posterior heights of of traumatic vertebra were significantly improved at 1 week, 1 year, and last follow-up when compared with preoperative ones (P < 0.05), but there was no significant difference between different time points after operation (P > 0.05). The neurological function was improved in different degrees; 1 case was rated as grade A, 4 cases as grade B, 7 cases as grade C, 15 cases as grade D, and 26 cases as grade E, showing significant difference when compared with preoperative one (Z=-5.477, P=0.000). ConclusionMinimally invasive passage in posterior laminotomy decompression, bone graft in the injured vertebrae combined with percutaneous pedicle screw fixation is an effective method to treat Denis type B thoracolumbar burst fractures, which not only can fully decompression, but also can effectively maintain the postoperative injured vertebral height, reduce the postoperative failure risk of internal fixation and decrease operation trauma.
