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: To explore clinical effect of arthroscopy-assisted rotator cuff tendon transfer in treating irreparable rotator cuff tears (IRCT). METHODS: From May 2015 to May 2018, 23 patients with unrepairable rotator cuff tears were treated with arthroscopy-assisted rotator cuff tendon transfer, and 21 patients were followed up finally, including 8 males and 13 females, aged from 48 to 82 years old with an average of(64.3±9.1) years old;the courses of disease ranged from 6 to 36 months with an average of (14.0±6.4) months. American Rotator and Elbow Surgeons Score(ASES) and Constant-Murley score were used to evaluate clinical efficacy before surgery and at the latest follow-up. RESULTS: All 21 patients were followed up for 36 to 54 months with an average of (39.4±4.4) months. Axillary incision of 1 patient was redness, swelling and exudation after surgery, which healed after 3 weeks of dressing change, and exudate culture was negative. At the latest follow-up, MRI showed partial tearing of the metastatic tendon in 2 patients, but pain and movement of the affected shoulder were still better than before surgery. ASES increased from preoperative (41.0±9.6) scores to the latest follow-up (75.6±14.0) scores, and had statistical difference (t=10.50, P<0.01). Constant-Murley score increased from (49.8±7.1) scores before operation to (67.5±11.6) scores at the latest follow-up (t=11.27, P<0.01). CONCLUSION Arthroscopic assisted latissimus dorsalis tendon transposition restores physiological and anatomical structure of glenohumeral joint by reconstructing balance of horizontal and vertical couples of shoulder joint, thus achieving the stability of the shoulder joint, relieving shoulder pain and improving shoulder joint function.

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 explore the clinical effects of three-dimensional printed preformed titanium mesh combined with latissimus dorsi muscle flap free transplantation in the treatment of wounds with skull defect after radical surgery of squamous cell carcinoma in the vertex. Methods: A retrospective observational study was conducted. From January 2010 to December 2019, 5 patients with squamous cell carcinoma in the vertex accompanied with skull invasion who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of the Second Affiliated Hospital of Air Force Medical University, including four males and one female, aged 50 to 65 years. The original lesion areas ranged from 5 cm×4 cm to 15 cm×8 cm. The titanium mesh was prefabricated via three-dimensional technic based on the result the scope of skull resection predicted with computerized tomography three-dimensional reconstruction before surgery. During the first stage, the soft tissue defect area of scalp (8 cm×7 cm to 18 cm×11 cm) after tumor enlargement resection was repaired with the preformed titanium mesh, and the titanium mesh was covered with latissimus dorsi muscle flap, with area of 10 cm×9 cm to 20 cm×13 cm. The thoracodorsal artery/vein was anastomosed with the superficial temporal artery/vein on one side. The muscle ends in the donor site were sutured together or performed with transfixion, and then the skin on the back were covered back to the donor site. On the 10th day after the first-stage surgery, the second-stage surgery was performed. The thin intermediate thickness skin graft was taken from the anterolateral thigh to cover the latissimus dorsi muscle flap. The duration and intraoperative blood loss of first-stage surgery were recorded. The postoperative muscle flap survival after the first-stage surgery and skin graft survival after the second-stage surgery was observed. The occurrence of complications, head appearance, and recurrence of tumor were followed up. Results: The average first-stage surgery duration of patients was 12.1 h, and the intraoperative blood loss was not more than 1 200 mL. The muscle flaps in the first-stage surgery and the skin grafts in the second-stage surgery all survived well. During the follow-up of 6-18 months, no complications such as exposure of titanium mesh or infection occurred, with good shape in the recipient sites in the vertex, and no recurrence of tumor. Conclusions: Three-dimensional printed preformed titanium mesh combined with latissimus dorsi muscle flap free transplantation and intermediate thickness skin graft cover is an effective and reliable method for repairing the wound with skull defect after extended resection of squamous cell carcinoma in the vertex. This method can cover the wound effectively as well as promote both recipient and donor sites to obtain good function and appearance.

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.

PURPOSE: The purpose of this study was to assess the effect of quilting suture extent on the latissimus dorsi myocutaneous flap (LDMCF) donor site and the necessity of drainage.METHODS: Clinical data of 136 breast cancer patients, who underwent breast reconstruction using LDMCF between May 2014 and December 2015, were retrospectively reviewed. Patients were divided into three groups. Group A: quilting sutures were performed on half of the LDMCF donor site and a closed suction drain was inserted. Group B: quilting sutures were performed for the entire LDMCF donor site and a closed suction drain was inserted. Group C: quilting sutures were performed for the entire LDMCF donor site and no drain was inserted. The duration of drainage, total drainage, length of hospital stay, number of postoperative aspirations for seroma removal, and total aspirated volume were compared.RESULTS: In the comparison of groups A and B, group B showed better results including the total amount of drained seroma, drain maintenance period, number of aspirations for seroma removal after drainage tube removal, total aspirated seroma, and hospitalization period with statistical significance (P<0.05). In the comparison of groups B and C, group C without drain showed no difference in all other variables except mean total drained seroma volume. Therefore, group C was superior to group A and there was no difference compared to group B with drain, even though the drain was not inserted.CONCLUSION: Total quilting suture at LDMCF donor site can reduce seroma formation and eliminate the need for a drain tube.

PURPOSE: The creation of the nipple-areola complex is the final stage in breast reconstruction and highly affects patient satisfaction. The neo-nipple is well known to shrink over time, particularly in the nipple projection. Currently, no reconstruction technique is clearly superior in terms of nipple size maintenance. We evaluated nipple size changes among several methods of breast mound reconstruction. METHODS: Seventy-eight patients received nipple-areola complex reconstruction secondarily after breast reconstruction. C-V flap nipple reconstructions were performed using a free transverse rectus abdominis myocutaneous (TRAM) flap in 25 cases (TRAM group), a latissimus dorsi (LD) myocutaneous flap in 27 cases (LD group), and an implant in 26 cases (implant group). The circumference and projection of the neo-nipple were measured using a flexible ruler, immediately after reconstruction and average 10 months after surgery. RESULTS: The overall circumference and projection at the final measurement were 91.43% ± 7.11% and 62.16% ± 21.55%, respectively, of immediate postoperative values. The change in circumference did not significantly differ among the 3 groups. In contrast, the change in projection was significantly worse in implant group compared to that in TRAM and LD groups. In addition, among the patients in implant group, greater inflation was significantly associated with greater decrease in the nipple projection. CONCLUSION: Breast mound reconstruction with autologous musculocutaneous flap techniques achieves better long-term maintenance of the neo-nipple projection compared to that achieved with expanded tissue and implantation. Considering the prospective loss of long-term nipple dimension, the preoperative design should be oversized in accordance with its origin in mound reconstruction.

Spinal accessory neuropathy (SAN) is commonly caused by an iatrogenic procedure, and that caused by tumors is very rare. We present a case of a 49-year-old man suffering from weakness in the right trapezius and sternocleidomastoid muscle. An electrophysiology study confirmed proximal SAN. Fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) revealed a diffuse large B-cell lymphoma compressing the right spinal accessory nerve. Ultrasonography showed definite atrophy on the trapezius and sternocleidomastoid muscles. In addition, post-chemotherapy FDG-PET/CT showed increased FDG uptake in the right upper trapezius, suggestive of denervation. This is the first report of SAN caused by direct compression by a diffuse large B-cell lymphoma, comprehensively assessed by an electrophysiology study, ultrasonography, and FDG-PET/CT.
