OBJECTIVE: To investigate the effectiveness of free latissimus dorsi myocutaneous flap transplantation combined with external fixation in the treatment of bone and soft tissue defects around the knee joint. METHODS: A retrospective analysis was conducted on the clinical data of 13 patients with high-energy trauma-induced bone and soft tissue defects around the knee joint admitted between January 2016 and July 2023. Among them, 11 were male and 2 were female, the age ranged from 23 to 61 years, with an average of 35.7 years. The causes of injury included 10 cases of traffic accident, 2 cases of machine entanglement injury, and 1 case of heavy object crush injury. According to the Gustilo-Anderson classification, 11 cases were type Ⅲ B and 2 cases were type Ⅲ C. Post-injury, 2 cases had wound infection and 2 cases had popliteal artery injury. The time from injury to flap repair was 40-49 days, with an average of 27.5 days. The wound size was 18 cm×13 cm to 32 cm×20 cm, all accompanied by distal femoral bone defects and quadriceps muscle defects. After primary debridement, vacuum sealing drainage combined with external fixation was used for treatment. In the second stage, free latissimus dorsi myocutaneous flaps were transplanted to repair soft tissue defects, with the flap size ranging from 20 cm×15 cm to 34 cm×22 cm. The donor sites of 9 flaps were directly sutured, and 4 cases with large tension were repaired with a keystone flap based on the posterior intercostal artery perforator. At 6-15 months postoperatively, with an average of 10.5 months, 11 patients underwent knee arthrodesis surgery; 2 patients with large bone defects at the distal femur and proximal tibia underwent multi-segment bone transport reconstruction of the bone defect. At last follow-up, the recovery of the flap and the donor site was recorded, and the function of the shoulder joint was evaluated by the American Shoulder and Elbow Surgeons (ASES) score, and the function of the affected knee joint was evaluated by the Knee Society Score (KSS). RESULTS: All the flaps survived after operation, the wounds and donor site incisions healed by first intention. All 13 patients were followed up 15-55 months, with an average of 21.6 months. Four patients who underwent the restoration of the donor site with the thoracodorsal keystone perforator flap had obvious scar hyperplasia around the wound, but no contracture or symmetrical breasts on both sides. At last follow-up, the appearance and texture of the flaps were good; the bony fusion of the knee joint was good, and the range of motion and function recovered well; the shoulder joint function on the flap-harvested side was not significantly affected, and the range of motion was satisfactory. The ASES shoulder joint score of the latissimus dorsi muscle-harvested side was 85-95, with an average of 89.5. The knee joint function KSS score was 75-90, with an average of 81.2. CONCLUSION Free latissimus dorsi myocutaneous flap transplantation combined with external fixation for the treatment of bone and soft tissue defects around the knee joint caused by high-energy trauma can repair bone and soft tissue defects and reconstruct the stability of the knee joint, effectively preserve the integrity of the limb and soft tissues, and improve the patient's ability of self-care.

OBJECTIVE: To explore the feasibility and effectiveness of a foldable pedicled latissimus dorsi myocutaneous flap to repair soft tissue defects in the shoulder and back. METHODS: Between August 2018 and January 2023, the foldable pedicled latissimus dorsi myocutaneous flaps were used to repair soft tissue defects in the shoulder and back of 8 patients. There were 5 males and 3 females with the age ranged from 21 to 56 years (mean, 35.4 years). Wounds were located in the shoulder in 2 cases and in the shoulder and back in 6 cases. The causes of injury were chronic infection of skin and bone exposure in 2 cases, secondary wound after extensive resection of skin and soft tissue tumor in 4 cases, and wound formation caused by traffic accident in 2 cases. Skin defect areas ranged from 14 cm×13 cm to 20 cm×16 cm. The disease duration ranged from 12 days to 1 year (median, 6.6 months). A pedicled latissimus dorsi myocutaneous flap was designed and harvested. The flap was divided into A/B flap and then were folded to repair the wound, with the donor area of the flap being pulled and sutured in one stage. RESULTS: All 7 flaps survived, with primary wound healing. One patient suffered from distal flap necrosis and delayed healing was achieved after dressing change. The incisions of all donor sites healed by first intention. All patients were followed up 6 months to 4 years (mean, 24.7 months). The skin flap has a good appearance with no swelling in the pedicle. At last follow-up, 6 patients had no significant difference in bilateral shoulder joint motion, and 2 patients had a slight decrease in abduction range of motion compared with the healthy side. The patients' daily life were not affected, and linear scar was left in the donor site. CONCLUSION The foldable pedicled latissimus dorsi myocutaneous flap is an ideal method to repair the soft tissue defect of shoulder and back with simple operation, less damage to the donor site, and quick recovery after operation.

Objective:Exploring the clinical application effect of a series of digital designed guide plates in the repair of mandibular defects with free fibular muscle flap. Methods:A total of 32 patients who underwent fibular muscle flap repair of mandibular defects in the Head and Neck Tumor Surgery Department of Xi'an Jiaotong University Stomatological Hospital were selected as the research subjects. They were divided into a guide plate assisted group（16 cases） and a conventional surgery group（16 cases） according to the different surgical methods. The guide plate assisted group completed the surgery with the assistance of a digital design series of guide plates, while the conventional surgery group served as the control. Record the preparation and shaping time of two groups of fibular myocutaneous flaps, evaluate the surgical effect at least 6 months after surgery, and conduct a patient satisfaction survey. Use SPSS 16.0 software package to statistically process the data. Results:The preparation and shaping time of the fibular muscle flap in the guide plate assisted group were significantly shorter than those in the conventional surgery group（P<0.05）. The excellent and good rate（87.5%） of the guide plate assisted group in evaluating the surgical effect was significantly higher than that of the conventional surgery group（75.0%）（P<0.05）. The satisfaction scores of patients in the guide plate assisted group for facial shape and bite function recovery were significantly higher than those in the conventional surgery group（P<0.05）, while there was no significant statistical difference in the satisfaction scores of pronunciation function recovery between the two groups（P>0.05）. Conclusion:The design of digital guide plates can improve the accuracy of repairing mandibular defects with fibular flaps, shorten the preparation and shaping time of fibular flaps, restore good facial appearance and bite relationship of patients, and improve satisfaction. It is worth promoting and applying in clinical practice, but the design accuracy still needs to be continuously improved.

OBJECTIVE: To explore the effectiveness of lobulated pedicled rectus abdominis myocutaneous flap to repair huge chest wall defect. METHODS: Between June 2021 and June 2022, 14 patients with huge chest wall defects were treated with radical resection of the lesion and lobulated pedicled rectus abdominis myocutaneous flap transplantation for reconstruction of chest wall defects. The patients included 5 males and 9 females with an average age of 44.2 years (range, 32-57 years). The size of skin and soft tissue defect ranged from 20 cm×16 cm to 22 cm×22 cm. The bilateral pedicled rectus abdominis myocutaneous flaps in size of 26 cm×8 cm to 35 cm×14 cm were prepaired and cut into two skin paddles with basically equal area according to the actual defect size of the chest wall. After the lobulated pedicled rectus abdominis myocutaneous flap was transferred to the defect, there were two reshaping methods. The first method was that the skin paddle at the lower position and opposite side was unchanged, and the skin paddle at the effected side was rotated by 90° (7 cases). The second method was that the two skin paddles were rotated 90° respectively (7 cases). The donor site was sutured directly. RESULTS: All 14 flaps survived successfully and the wound healed by first intention. The incisions at donor site healed by first intention. All patients were followed up 6-12 months (mean, 8.7 months). The appearance and texture of the flaps were satisfactory. Only linear scar was left at the donor site, and the appearance and activity of the abdominal wall were not affected. No local recurrence was found in all tumor patients, and distant metastasis occurred in 2 breast cancer patients (1 liver metastasis and 1 lung metastasis). CONCLUSION The lobulated pedicled rectus abdominis myocutaneous flap in repair of huge chest wall defect can ensure the safety of blood supply of the flap to the greatest extent, ensure the effective and full use of the flap tissue, and reduce postoperative complications.

Objective: To investigate the method and effect of free anterolateral thigh myocutaneous flap combined with pedicled latissimus dorsi myocutaneous flap transfer for functional reconstruction after resection of huge shoulder tumor. Methods: The clinical data of 6 patients who were treated with pedicled latissimus dorsi myocutaneous flap combined with free anterolateral thigh myocutaneous flap to repair large-area complex defects after shoulder tumor resection at Department of Oncology Plastic Surgery, Hunan Province Cancer Hospital from December 2015 to December 2020 were retrospectively analyzed. There were 2 males and 4 females, with an average age of 41.7 years (range:29 to 56 years). There were 2 cases of synovial sarcoma,2 cases of phylloid cell sarcoma,1 case of liposarcoma and 1 case of fibrosarcoma. Before this operation, tumor resection had been performed for 1 to 5 times on each case,and the course of disease was 6 to 24 months. Pedicled latissimus dorsi myocutaneous flap combined with free anterolateral thigh myocutaneous flap were used to repair soft tissue defects and reconstruct deltoid function. Postoperative flap status, complications, appearance and function of upper limbs and tumor recurrence were recorded. Results: Six patients were followed up for an average of 21.6 months (range: 12 to 36 months). There were no serious complications after operation,and all flaps survived. No tumor recurrence was found. The appearance of shoulder contour reconstructed by flaps was satisfactory. The reinnervation effect of lateral femoral muscle was confirmed recovered smoothly by neuroelectromyography 3 months after operation. Shoulder function was mildly limited in 3 patients,moderately limited in 2 patients and severely limited in 1 patient. All patients reported significant improvement in shoulder discomfort.The overall functional results of all patients were satisfactory. Conclusion: Combined myocutaneous flaps transplantation can perfectly repair the wound left after the resection of huge shoulder tumor,minimize the recurrence of tumor,reconstruct the function of shoulder joint and greatly improve the quality of life of patients.

Objective: To observe the clinical effects of free latissimus dorsi myocutaneous flap combined with artificial dermis and split-thickness skin graft in the treatment of degloving injury in lower limbs. Methods: A retrospective observational study was conducted. From December 2017 to December 2020, 8 patients with large skin and soft tissue defect caused by degloving injury in lower extremity were admitted to Ningbo No.6 Hospital, including 5 males and 3 females, aged from 39 to 75 years, with wound area of 25 cm×12 cm-61 cm×34 cm. The free latissimus dorsi myocutaneous flap with latissimus dorsi muscle in the width of 12-15 cm and flap area of 20 cm×8 cm-32 cm×8 cm was used to repair the skin and soft tissue defect of bone/tendon exposure site or functional area. The other defect was repaired with bilayer artificial dermis, and the flap donor site was sutured directly. After the artificial dermis was completely vascularized, the split-thickness skin graft from thigh was excised and extended at a ratio of 1∶2 to 1∶4 and then transplanted to repair the residual wound, and the donor site of skin graft was treated by dressing change. The survival of latissimus dorsi myocutaneous flap, artificial dermis, and split-thickness skin graft after operation was observed, the interval time between artificial dermis transplantation and split-thickness skin graft transplantation was recorded, and the healing of donor site was observed. The appearance and function of operative area were followed up. At the last outpatient follow-up, the sensory recovery of flap was evaluated by British Medical Research Council evaluation criteria, the flap function was evaluated by the comprehensive evaluation standard of flap in Operative Hand Surgery, the scar of lower limb skin graft area and thigh skin donor area was evaluated by Vancouver scar scale, and the patient's satisfaction with the curative effects was asked. Results: The latissimus dorsi myocutaneous flap survived in 6 patients, while the distal tip of latissimus dorsi myocutaneous flap was partially necrotic in 2 patient and was repaired by skin grafting after resection at split-thickness skin grafting. The artificial dermis survived in all 8 patients after transplantation. The split-thickness skin graft survived in 7 patients, while partial necrosis of the split-thickness skin graft occurred in one patient and was repaired by skin grafting again. The interval time between artificial dermis transplantation and split-thickness skin graft transplantation was 15-26 (20±5) d. The donor site of latissimus dorsi myocutaneous flap healed with linear scar after operation, and the thigh skin graft donor site healed with scar after operation. The patients were followed up for 6-18 (12.5±2.3) months. The color and elasticity of the flap were similar to those of the surrounding skin tissue, and the lower limb joint activity returned to normal. There was no increase in linear scar at the back donor site or obvious hypertrophic scar at the thigh donor site. At the last outpatient follow-up, the sensation of the flap recovered to grade S₂ or S₃; 3 cases were excellent, 4 cases were good, and 1 case was fair in flap function; the Vancouver scar scale score of lower limb skin graft area was 4-7 (5.2±0.9), and the Vancouver scar scale score of thigh skin donor area was 1-5 (3.4±0.8). The patients were fairly satisfied with the curative effects. Conclusions: In repairing the large skin and soft tissue defect from degloving injury in lower extremity, to cover the exposed bone/tendon or functional area with latissimus dorsi myocutaneous flap and the residual wound with artificial dermis and extended split-thickness skin graft is accompanied by harvest of small autologous flap and skin graft, good recovery effect of functional area after surgery, and good quality of healing in skin grafted area.

Objective: To evaluate the functional outcomes of repairing parietal and occipital defect after surgery for cancer by lower trapezius myocutaneous flap with latissimus dorsi. Methods: Retrospective analyses of eight patients were performed who underwent repairing parietal and occipital defects with dural exposure after surgeries for cancers from January 2015 to January 2020 in Tianjin Institute of Occupational Disease Control and Prevention (Tianjin Workers Hospital) and the Second Hospital of Tianjin Medical University, including 6 males and 2 females aged from 26 to 68 years old. The method for harvesting the lower trapezius myocutaneous flap was improved and thus the lower trapezius myocutaneous flaps with latissimus dorsi were used for repairing the parietal and occipital defects. The area of myocutaneous flap depended on the size of defect. Results: The defects were repaired with the flaps with areas ranging from 12 cm×8 cm to 17 cm×15 cm. Seven flaps survived after surgery and the wounds were healed. Blisters and bruise were observed at the distal end of one flap 2 days after operation, which were cured with dressing change for 10 days. All cases were followed-up for six months, with normal functions of the shoulder joints, aside from mild hypertrophic scar in donor site on the back. Conclusion: It is feasible to use the lower trapezius myocutaneous flap with latissimus dorsi to repair the parietal and occipital defect after surgery for cancer, and the clinical effect is satisfactory.

Large and ptotic breast reconstruction in patients who are not candidates for a transverse rectus abdominalis myocutaneous flap and revision surgery for the contralateral breast remains challenging. We developed a novel breast reconstruction technique using a latissimus dorsi myocutaneous (LD m-c) flap set at the posterior aspect of the reconstructed breast, combined with an anatomical silicone breast implant (SBI), following tissue expander surgery. We performed the proposed technique in four patients, in whom the weight of the resected tissue during mastectomy was >500 g and the depth of the inframammary fold (IMF) was >3 cm. After over-expansion of the lower portion of the skin envelope by a tissue expander, the LD m-c flap was transferred to cover the lower portion of the breast defect and to achieve a ptotic contour, with the skin paddle set at the posterior aspect of the reconstructed breast. An SBI was then placed in the rest of the breast defect after setting the LD m-c flap. No major complications were observed during the follow-up period. The proposed technique resulted in symmetrical and aesthetically satisfactory breasts with deep IMFs, which allowed proper fitting of the brassiere, following large and ptotic breast reconstruction.

Descending branch of the lateral circumflex femoral artery (LCFA) is commonly used pedicle for ante- rolateral thigh (ALT) flap. Oblique branch of LCFA is an alternative pedicle that can be used in micro- vascular surgery. According to review of literature and to the best of our knowledge we could not find the use of oblique branch of LCFA as a pedicle of the ALT flap in regional soft tissue reconstruction. Here we presented a case of a 55-year-old man sustaining soft tissue injury and wound over the left trochanteric and gluteal region following a road traffic accident, who was treated by the use of extended ALT pedicle flap with oblique branch of LCFA as the pedicle for reconstruction of soft tissue defect in trochanteric and gluteal regions with successful outcome.

OBJECTIVETo explore the clinical effects of ipsilateral lower trapezius myocutaneous flap for repairing cervical ulcer as a result of radiotherapy after radical mastectomy.

METHODSSix patients with cervical ulcers as a result of radiotherapy after radical mastectomy were hospitalized from March 2010 to February 2015, suffering from persistent pain in different degrees. The wound area ranged from 6 cm × 4 cm to 10 cm × 6 cm before debridement, 8 cm × 5 cm to 16 cm × 10 cm after debridement. Ipsilateral lower trapezius myocutaneous flap was used to repair the wound after thorough debridement, with the area ranging from 10 cm × 7 cm to 20 cm × 13 cm. The donor sites were sutured directly or covered with medium-thickness skin graft obtained from the back.

RESULTSPain was obviously relieved in all the patients 2 days after surgery. The wounds in five patients were healed, while necrosis of superficial skin approximately 1 cm in diameter appeared at the distal end of one myocutaneous flap, and it healed after dressing change. During the follow-up period of 3 to 18 months, no recurrence of ulcer was found, the texture of the myocutaneous flaps was soft with good appearance, and the donor sites healed well.

CONCLUSIONSOn the basis of thorough debridement, it is feasible to repair the cervical ulcer as a result of radiotherapy after radical mastectomy with the ipsilateral lower trapezius myocutaneous flap.
