Objective To explore the effectiveness of the improved pedicled superficial iliac circumflex artery flap for repairing serious wound of the hand and forearm. Methods Between June 2008 and June 2011, 13 cases of serious wound of the hand and forearm were treated. There were 9 males and 4 females with a mean age of 41 years (range, 23-64 years). The disease causes included twist injury by machine in 2 cases, wire rope squeezed injury in 4 cases, traffic accident injury in 3 cases, crushing injury in 2 cases, high voltage electrical injury in 1 case, and snake bites in 1 case. There were 10 cases of fresh wounds and 3 cases of infection and necrosis wounds, and all had bone and tendon exposure. The skin and soft tissue defects ranged from 7 cm × 3 cm to 22 cm × 6 cm. The pedicled iliac artery flap was used in 8 cases, and pedicled iliac artery composite flap in 5 cases. The flap size ranged from 12 cm × 4 cm to 27 cm × 8 cm, with the flap pedicle of 2-4 cm wide strip and 3-5 cm wide fascia. Results The pedicle of flap was cut at 3 weeks in 12 patients, and at 4 weeks in 1 patient who had partial avulsion and hemorrhage at 1 week after operation. All flaps survived and incisions at donors and wounds healed by first intention. Eleven patients were followed up 6-36 months (mean, 20 months). The flap color and texture were good; 3 bulky flaps were observed, and satisfactory appearance was achieved after skin flap thinning. After 6 months, the protective sensation recovered in all cases; according to the Hand Surgery Society of Chinese Medical Association evaluation of upper extremity function trial standard for total active motion of the fingers, the results were excellent in 9 cases, good in 1 case, and poor in 1 case. Conclusion Improved fascia pedicled superficial iliac circumflex artery skin flap can repair serious hand and forearm injury, which is easy-to-operate and less injury at donor site.
【Abstract】 Objective To explore the effect of early scrotal dermatoplasty on spermatogenic functional rehabilitation of testis in juvenile pigs with third degree burn wound of the scrotum. Methods Thirty healthy male Guizhou miniature pigs (weighing 10-15 kg, 2-month-old) were divided into 3 groups: control group (group A, n=10), natural healing group (group B, n=10), and dermatoplasty group (group C, n=10). In group A, the pig was not given any treatment; after third degree burn model of the scrotum was prepared, wounds were not treated in group B and the burn skin was excised and whole hypogastric pachydermia was used for dermatoplasty in group C. At 3 months and 1 year after model preparation, bilateral testis were collected from 5 pigs, respectively. HE staining was performed to observe the effects of different repair method on the morphology of spermatogenic cells and immunohistochemical staining was used to detect Survivin protein expression. Results All pigs survived to the end of the experiment and the wound healed successfully. Histological observation showed that spermatogenic cells had normal shape at all stages and mature sperms were seen in lumens in group A; the thickness of seminiferous epithelium was thinner, having one layer or two layers of spermatogenic cells in group B; the spermatogenic cells in group C were slightly more than that in group B with some spermatids; and in groups B and C, the spermatogenic cells at 1 year were more than that at 3 months. Immunohistochemistry staining showed that the Survivin protein expression in groups B and C was less than in group A, and group B was less than group C, showing significant differences at 3 months and 1 year (P lt; 0.05), but no significant difference between 3 months and 1 year in the same group (P gt; 0.05). Conclusion Dermatoplasty has inhibitory effect on spermatogenic functional rehabilitation of testis. Dermatoplasty can decrease spermatogenic cells and reduce Survivin protein expression, but some spermatids still survive in seminiferous tubule.
Objective To investigate the effectiveness of latissimus dorsi Kiss flap for repairing composite tissue defects and functional reconstruction of upper arm. Methods Between March 2010 and November 2016, 12 cases of composite tissue defects of upper arm were repaired by latissimus dorsi Kiss flap with blood vessel and nerve bunch. There were 8 males and 4 females with a median age of 34 years (range, 21-50 years). The reason of injury included plowing mechanical injury in 4 cases, traffic accident injury in 5 cases, electrical injury in 2 cases, and resecting upper arm soft tissue sarcoma in 1 case. There were deltoid defect in 5 cases, triceps brachii and brachialis defect in 4 cases, and deltoid, triceps brachii, and brachialis damaged in varying degrees in 3 cases. The defect area ranged from 13 cm×7 cm to 20 cm×8 cm. Among them, there were 6 cases of fracture combined with partial bone exposure, one of them with bone defect. The disease duration was 3 hours to 6 months. The flap size ranged from 10 cm×6 cm to 15 cm×7 cm, and the donor sites were directly sutured. Results Twelve flaps survived with primary healing of wounds. Ten patients were followed up 6-26 months (mean, 14 months). At last follow-up, the flaps were soft and the skin color was similar to the surrounding skin. No obvious scar was found at donor sites. The abduction range of motion of shoulder was 30-90°. The muscle strength of brachialis were all at grade 4 or above. The superficial sensation and tactile sensation recovered partialy (S1 in 2 cases, S2 in 6 cases, S3 in 2 cases). According to Society of Hand Surgery standard for the evaluation of upper part of the function, the shoulder joint function was excellent in 2 cases, good in 4 cases, and fair in 4 cases. Conclusion The design of the latissimus dorsi Kiss flaps are flexible, and the donor site can be directly sutured, with the nerves of the latissimus dorsi muscle can partialy reconstruct abduction function of upper arm. In general, the Kiss flap repairing upper arm defect can obtain satisfactory effectiveness.
ObjectiveTo explore the clinical application of the flap supported by perforating branch of the radial artery superior wrist catena-form blood vessel in repairing hand and wrist wound. MethodsBetween March 2010 and March 2013, 24 cases of severe wounds in wrist were repaired with the flap supported by perforating branch of forearm radial artery and catena-form blood vessel. There were 15 males and 9 females, aged 19-54 years (mean, 37 years). In 22 patients with trauma, there were 9 cases of machine injury, 5 cases of traffic accident injury, 5 cases of crash injury of heavy objects, 1 case of sharp instrument injury, and 2 cases of electrical injury, with a mean disease duration of 11 days (range, 2-20 days). In 2 patients with tumor excision wound, there were 1 case of right forearm liposarcoma and 1 case of left forearm squamous-cell carcinoma, with the disease duration of 7 days and 3 months, respectively. All cases complicated by bone and tendon exposure. The size of defect was 4.5 cm×4.0 cm to 10.0 cm×7.5 cm, and the size of the flap was 6.0 cm×4.0 cm to 20.0 cm×8.5 cm. The donor site was directly sutured or repaired by skin graft. ResultsPartial flap necrosis occurred in 1 case, and was cured after dressing change; the other flaps survived, and primary healing of incision was obtained. The patients were followed up 6-36 months (mean, 20 months). The flap featured good color and texture, and also recovered protective sensation at 6 months after operation, with a mean two-point discrimination of 12 mm (range, 11-14 mm). No ulcers of the flap was observed. At last follow-up, according to Hand Surgery Society of Chinese Medical Association for functional evaluation of upper limb, the function was rated as excellent in 19 cases, good in 4 cases, and fair in 1 case. ConclusionThe flap supported by perforating branch of forearm radial artery and catena-form blood vessel can be used to repair wound in wrist, which has no injury to the radial artery, and it also could be used for the patients with ulnar and radial artery injuries. Thus it is an ideal method to repair wound in the wrist because the operation is simple, and the flap has good appearance and texture.
Objective To investigate the feasibility and effectiveness of designing wide pedicle of abdominal pedicled flap and repairing large skin defect of upper limb with improved suture method. Methods Between March 2014 and August 2016, 11 cases with hand and forearm skin soft tissue defect were repaired with abdominal pedicled flaps. Among them, 8 cases were male and 3 were female; aged 18-65 years (mean, 38 years). The causes of injury were machinery injury in 7 cases and traffic accident in 4 cases. The wound located at left upper limb in 6 cases and right upper limb in 5 cases. The size of wound ranged from 12 cm×7 cm to 20 cm×10 cm. The interval from injury to operation was 2-5 days (mean, 4 days). Four cases were repaired with lower abdominal flap and 7 with umbilical flap. The size of flap ranged from 10 cm×9 cm to 22 cm×10 cm. And the flap was designed with wide pedicle at width of 8 to 18 cm (mean, 15 cm); then the wound was sutured with improved method. The pedicle was cut after 3 weeks. Results All the flaps survived without congestion, necrosis, and tension blisters. The wound and the incision were both healed at stage Ⅰ. All patients were followed up 4-12 months (mean, 8 months). The skin color, texture, and shape were satisfying, and no ulcer formed. Only line-like scar left at the donor site. Conclusion Abdominal pedicled flap with wide pedicle and improved suture method can reduce the abdominal skin waste, avoid postoperative infection, and be feasible to repair large skin defect of upper limb with advantages of simple operation and reliable fixation.
