OBJECTIVE: To evaluate the effectiveness of combined anterolateral thigh-ilioinguinal Flow-through flaps for repairing complex lower limb defects. METHODS: A clinical data of 20 patients with complex lower limb injuries admitted between January 2018 and January 2024 was retrospectively analyzed. The cohort included 14 males and 6 females with an average age of 47.3 years (range, 29-65 years). Injury mechanisms comprised heavy-object trauma (n=7), traffic accidents (n=5), machinery crush injuries (n=5), and osteomyelitis (n=3). Defects involved the left (n=7) and right (n=13) limbs, with anatomical distributions including tibiofibular injuries (n=6), isolated tibial injuries (n=6), foot and ankle injuries (n=5), and femoral-tibial injuries (n=3). The size of soft tissue defects ranged from 23 cm×8 cm to 44 cm×12 cm. Reconstruction employed combined anterolateral thigh-ilioinguinal Flow-through flaps in the size of 24 cm×10 cm to 48 cm×14 cm. The recipient sites were sutured in primary closure in 12 cases, and 8 cases had no available vascular anastomosis sites in the recipient sites, and a cross-leg flap form was used to establish a temporary blood supply, and the flaps were cut off after 3-4 weeks. The donor sites in the thigh were directly sutured. During follow-up, the survival of the flaps, appearance, texture, and related complications were observed; the Vancouver scar scale (VSS) score was used to evaluate the scar condition of the flaps, the lower extremity function scale (LEFS) score was used to evaluate the function of the affected lower limb, and the visual analogue scale (VAS) score was used to evaluate the pain condition of the affected side. RESULTS: Postoperatively, the flap complete necrosis occurred in 1 case, marginal necrosis in 1 case, superficial infections in 2 cases, and venous thrombosis in 1 case. The remaining flaps survived completely with primary wound healing at both recipient and donor sites. Limb salvage was achieved in all patients. All patients were followed up with 12-24 months (mean, 18.4 months). All flaps had satisfactory color, texture, and contour. Fractures reached clinical union in all cases. Donor site morbidity included mild contralateral hip flexion/knee extension limitation (n=1), persistent hypoesthesia (n=3), and chronic pain (n=1) at 6 months. At 12 months after operation, the LEFS, VSS, and VAS scores on the affected side were 62.7±4.6, 3.5±1.1, and 1.2±0.6, respectively, which were superior to those at 1 month after operation (38.6±2.8, 8.5±1.4, 4.7±1.1), and the differences were significant (P<0.05). CONCLUSION The anterolateral thigh-ilioinguinal Flow-through flaps for repairing complex lower limb injuries is a good method. The distal blood supply of the affected side recover well, the survival rate of the flap is high, and the function recovery of the affected limb is good.

OBJECTIVE: To investigate the effectiveness of Flow-through bridge anterolateral thigh flap transplantation in the treatment of complex calf soft tissue defects. METHODS: The clinical data of the patients with complicated calf soft tissue defects, who were treated with Flow-through bridge anterolateral thigh flap (study group, 23 cases) or bridge anterolateral thigh flap (control group, 23 cases) between January 2008 and January 2022, were retrospectively analyzed. All complex calf soft tissue defects in the two groups were caused by trauma or osteomyelitis, and there was only one major blood vessel in the calf or no blood vessel anastomosed with the grafted skin flap. There was no significant difference between the two groups in general data such as gender, age, etiology, size of leg soft tissue defect, and time from injury to operation ( P>0.05). The lower extremity functional scale (LEFS) was used to evaluate the sufferred lower extremity function of the both groups after operation, and the peripheral blood circulation score of the healthy side was evaluated according to the Chinese Medical Association Hand Surgery Society's functional evaluation standard for replantation of amputated limbs. Weber's quantitative method was used to detect static 2-point discrimination (S2PD) to evaluate peripheral sensation of the healthy side, and the popliteal artery flow velocity, toenail capillary filling time, foot temperature, toe blood oxygen saturation of the healthy side, and the incidence of complications were compared between the two groups. RESULTS: No vascular or nerve injury occurred during operation. All flaps survived, and 1 case of partial flap necrosis occurred in both groups, which healed after free skin grafting. All patients were followed up 6 months to 8 years, with a median time of 26 months. The function of the sufferred limb of the two groups recovered satisfactorily, the blood supply of the flap was good, the texture was soft, and the appearance was fair. The incision in the donor site healed well with a linear scar, and the color of the skin graft area was similar. Only a rectangular scar could be seen in the skin donor area where have a satisfactory appearance. The blood supply of the distal limb of the healthy limb was good, and there was no obvious abnormality in color and skin temperature, and the blood supply of the limb was normal during activity. The popliteal artery flow velocity in the study group was significantly faster than that in the control group at 1 month after the pedicle was cut, and the foot temperature, toe blood oxygen saturation, S2PD, toenail capillary filling time, and peripheral blood circulation score were significantly better than those in the control group ( P<0.05). There were 8 cases of cold feet and 2 cases of numbness on the healthy side in the control group, while only 3 cases of cold feet occurred in the study group. The incidence of complications in the study group (13.04%) was significantly lower than that in the control group (43.47%) ( χ ²=3.860, P=0.049). There was no significant difference in LEFS score between the two groups at 6 months after operation ( P>0.05). CONCLUSION Flow-through bridge anterolateral thigh flap can reduce postoperative complications of healthy feet and reduce the impact of surgery on blood supply and sensation of healthy feet. It is an effective method for repairing complex calf soft tissue defects.

A male patient weighing 2.5 kg was admitted for respiratory difficulty, and a large ventricular septal defect (VSD) was diagnosed. During care, sudden right leg swelling with a femur shaft fracture occurred. The patient's father had a history of recurrent lower extremity fractures; thus, osteogenesis imperfecta was considered. The patient's respiratory difficulty became aggravated, and VSD repair in the neonatal period was therefore performed with gentle sternal traction and great vessel manipulation under total intravenous anesthesia to prevent malignant hyperthermia. The patient was discharged without notable problems, except minor wound dehiscence. Outpatient genetic testing revealed that the patient had a COL1A1/COL1A2 mutation.

PURPOSE: Defects around the distal one third of the leg and ankle are difficult to manage by conservative measures or simple split thickness skin graft. Distally based peroneus brevis muscle flap is a well described flap for such defects. METHODS: This is a retrospective analysis conducted on 25 patients with soft tissue and bony defects of distal third of lower leg and ankle, which were treated using distally based peroneus brevis muscle flap from January 2013 to January 2018. Information regarding patient demographics, etiology, size and location of defects and complications were collected. All patients were followed up for at least 3 months after surgery. RESULTS: There were 21 males and 4 females with the mean age of 39 (5-76) years. The most common cause of injuries was road traffic accident, followed by complicated open injury. The average size of defects was 20 (4-50) cm. The mean operating time was 75 (60-90) min for flap harvest and inset. We had no patient with complete loss of the flap. Five patients (20%) had marginal necrosis of the flap and two patients have graft loss due to underlying hematoma and required secondary split thickness skin grafting. CONCLUSION The distally based peroneus brevis muscle flap is a safe option with reliable anatomy for small to moderate sized defects following low velocity injury around the ankle. The commonest complication encountered is skin graft loss which can be reduced by primary delayed grafting.

PURPOSETo express the versatility of a variety of non-microsurgical skin flaps used for coverage of difficult wounds in the lower third of the leg and the foot over 4 years period. Five kinds of flaps were used. Each flap was presented with detailed information regarding indication, blood supply, skin territory and technique.

METHODSAltogether 26 patients underwent lower leg reconstruction were included in this study. The reconstructive procedures applied five flaps, respectively distally based posterior tibial artery perforator flap (n = 8), distally based peroneal artery perforator flap (n = 4), distally based sural flap (n = 6), medial planter artery flap (n = 2) and cross leg flaps (n = 6).

RESULTSIn all cases, there were no signs of osteomyelitis of underlying bones or discharge from the undersurface of the flaps. Fat necrosis occurred at the distal end of posterior tibial artery perforator flap in one female patient. The two cases of medial planter artery flap showed excellent healing with closure of donor site primarily. One cross leg flap had distal necrosis.

CONCLUSIONWould at lower third of leg can be efficiently covered by posterior tibial, peroneal artery and sural flaps. Heel can be best covered by nearby tissues such as medial planter flap. In presence of vascular compromise of the affected limb or exposure of dorsum of foot, cross leg flap can be used.

OBJECTIVETo explore the feasibility and the effect of free chimeric perforator flap with deep inferior epigastric artery for the soft tissue defect on the lower extremity with deep dead space.

METHODSFrom Mar. 2010 to Aug. 2011, 8 patients with soft tissue defects on the lower extremities combined with dead space, bone or joint exposure were reconstructed with free hinged perforator flaps with deep inferior epigastric artery. The muscle flap was inserted into the deep dead space, with perforator flap for superficial defect. The defects on the donor sites were closed directly.

RESULTSAll the flaps survived with primary healing. Good color and texture was achieved. The patients were followed up for 12-24 months, with an average of 16 months. 2 over-thick flaps were treated by flap-thinning surgery. Only linear scar was left on the donor site on abdomen with no malfunction.

CONCLUSIONSThe free chimeric perforator flap with deep inferior epigastric artery can simultaneously construct the dead space and superficial defect with only anastomosis of one set of vascular pedicle. It is an ideal method with good results on recipientsites and less morbidity on donor sites.

OBJECTIVETo summarize the clinical application results of the repair soft tissue defect in contralateral leg with a cross-leg soleus muscle flap pedicle transplantation.

METHODSFrom January 2008 to January 2013, 8 patients with soft-tissue defect in lower leg underwent reconstruction with a cross-leg soleus muscle flap pedicle transplantation (without microvascular anastomoses). There were 7 males and 1 female, aged from 20 to 49 years old with an average of 31.8 years. The operative time after injury was from 2 to 8 weeks with the mean of 46 days. The soleus muscle flap was transposed across to the contralateral leg defect area, then immediate to perform the coverage of the muscle flaps by a meshed split-thickness skin graft. The donor site was closed directly.

RESULTSAll the muscle flaps had survived completely. In one case, recipient area edge had a less exudate from drainage hole everyday, the incision spontaneously was healed after 2 week's changing dressing. Follow-up period ranged form 1.5 to 4 years with an average of 2.5 years postoperatively. The tibia and fibula fractures were healed well. A good contour was achieved at the recipient area. According to LEM standard, 2 cases got excellent results, 5 good and 1 fair.

CONCLUSIONSoleus flap pedicle transplantation is very suitable to repair the soft tissue defect of the injuried leg only one main blood vessel, and can reduce the damage of donor area.

This case demonstrates a rare variation in the pattern of injury and the presentation of acute lateral compartment syndrome of the leg. Although uncommon, lateral compartment syndrome of the leg after an ankle inversion leading to peroneus longus muscle rupture has been previously documented. This case was unusual because there was no overt ankle injury and the patient was able to continue physical activity, in spite of a significant rupture of the peroneus longus muscle that was determined later. This case highlights the necessary vigilance clinicians must maintain when assessing non-contact injuries in patients with possible compartment syndrome.

OBJECTIVETo investigate the clinical application of flow-through deep inferior epigastric perforator flaps for reconstruction of large defects at the extremities.

METHODSThe deep inferior and superior epigastric arteries were designed as the axial vessel and the arterial supply to the flap was the paraumbilical perforator artery. Free deep inferior epigastric perforator flaps were harvested in flow- through manners to reconstruct associated arterial defect in the wound. The sensation assessment,Enneking score,and questionnaire of the flap aesthetic were all performed during follow-up period.

RESULTSFrom December 2011 to September 2012, 5 patients with large defects at extremities were treated. The deep inferior and superior epigastric arteries were designed as the axial vessel and the arterial supply to the flap was the paraumbilical perforator artery. The wound defects ranged form 11 cm x 5 cm to 30 cm x 11 cm. And the flap size ranged from 13 cm x7 cm to 33 cm x 13 cm. All flaps survived completely. The recipient arteries were all bypassed well documented by color Doppler examinations. All cases had 12-24 months' follow-up period. The flaps had good appearance and high aesthetic satisfactory(100%). 12 months after operations, sensation assessment were all S3+, and the Enneking score ratios were 82%-95% ,with 87.2% in average.

CONCLUSIONSFlow-through deep inferior epigastric perforator flaps are reliable and effective for reconstruction of large defects at the extremities with maintenance of the vascular status of the extremities. The flaps can also be designed in transverse or oblique mode for clinical application.
