There were 7 males and 2 females, aged 21-61 years (mean, 39.8 years). The body mass index ranged from 19.49 to 26.45 kg/m² (mean, 23.85 kg/m²). Causes of injury included 5 cases of traffic accident injuries and 4 cases of machine crush injuries. There were 3 cases of leg wounds, 2 cases of foot wounds, and 4 cases of hand wounds. After debridement, the size of wound ranged from 7 cm×4 cm to 13 cm×11 cm. The time from admission to flap repair surgery was 5-12 days (mean, 7 days). Preoperatively, perforator localization was performed using a traditional Doppler flow detector and infrared thermography, respectively.

Preoperatively, all patients exhibited bone defects ranging from 2.0 to 6.5 cm and soft tissue defects ranging from 10 to 210 cm&lt;sup&gt;2&lt;/sup&gt;. Reconstruction was performed using functional perforator flaps based on the superficial circumflex iliac artery and chimeric iliac bone flaps.

There were 17 males and 4 females, aged 25-67 years (mean, 44 years). There were 19 cases of femoral anterograde intramedullary nail fixation, 1 case of femoral retrograde intramedullary nail fixation, and 1 case of steel plate fixation with fatigue fracture. There were 9 cases of hypertrophic non-union and 12 cases of atrophic non-union. All patients had varying degrees of fracture end atrophy/sclerosis. Among them, 20 patients who were fixed with intramedullary nails underwent removal of soft tissue and hardened bone at the fracture end, and cortical treatment resulted in the appearance of \"chili sign\" at the fracture end. Iliac bone grafting and anti-rotation steel plate fixation were performed. One patient with steel plate fixation was removed the steel palte and fixed with a retrograde intramedullary nail, while the hardened bone at the fracture end was removed, iliac bone grafting and anti-rotation steel plate fixation were performed. Postoperative follow-up observation included the incision healing, maximum knee flexion range of motion, bone healing, length of lower limbs, and subjective satisfaction.

Their morphology, microstructure, elemental composition and distribution, diameter, and molecular constitution were characterized using scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and energy-dispersive spectroscopy. Femurs and tibias were harvested from twelve 4-week-old Sprague Dawley rats, and bone marrow mesenchymal stem cells (BMSCs) were isolated and cultured using the whole bone marrow adherent method, followed by passaging. The third passage cells were identified as stem cells by flow cytometry and then co-cultured with nanoflowers at concentrations of 0, 0.4, 0.8, 1.2, 1.6, 2.0, 2.4, 2.8, 3.2, and 3.6 mg/mL. Cell counting kit 8 (CCK-8) assay was performed to screen for the optimal concentration that demonstrated the best cell viability, which was subsequently used as the experimental concentration for further studies. After co-culturing BMSCs with the screened concentration of nanoflowers, the biocompatibility of the nanoflowers was verified through live/dead cell staining, scratch assay, and cytoskeleton staining. The antioxidant capacity was assessed by using reactive oxygen species (ROS) fluorescence staining. The &lt;i&gt;in vitro&lt;/i&gt; osteoinductive ability was evaluated via alkaline phosphatase (ALP) staining, alizarin red staining, and immunofluorescence staining of osteocalcin (OCN) and Runt-related transcription factor 2 (RUNX2). All the above indicators were compared with the control group of normally cultured BMSCs without the addition of nanoflowers.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Scanning electron microscopy revealed that the prepared nanoflowers exhibited a flower-like structure; transmission electron microscopy scans discovered that the nanoflowers possessed a multi-layered structure, and high-magnification images displayed continuous atomic arrangements, with the nanoflower diameter measuring (2.00±0.25) μm; energy-dispersive spectroscopy indicated that the nanoflowers contained elements such as C, N, O, P, and Ca, which were uniformly distributed across the flower region; Fourier transform infrared spectroscopy analyzed the absorption peaks of each component, demonstrating the successful preparation of the nanoflowers. Through CCK-8 screening, the concentrations of 0.8, 1.2, and 1.6 mg/mL were selected for subsequent experiments. The live/dead cell staining showed that nanoflowers at different concentrations exhibited good cell compatibility, with the 1.2 mg/mL concentration being the best (&lt;i&gt;P&lt;/i&gt;&lt;0.05).

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 (&lt;i&gt;n&lt;/i&gt;=7), traffic accidents (&lt;i&gt;n&lt;/i&gt;=5), machinery crush injuries (&lt;i&gt;n&lt;/i&gt;=5), and osteomyelitis (&lt;i&gt;n&lt;/i&gt;=3). Defects involved the left (&lt;i&gt;n&lt;/i&gt;=7) and right (&lt;i&gt;n&lt;/i&gt;=13) limbs, with anatomical distributions including tibiofibular injuries (&lt;i&gt;n&lt;/i&gt;=6), isolated tibial injuries (&lt;i&gt;n&lt;/i&gt;=6), foot and ankle injuries (&lt;i&gt;n&lt;/i&gt;=5), and femoral-tibial injuries (&lt;i&gt;n&lt;/i&gt;=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.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;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 (&lt;i&gt;n&lt;/i&gt;=1), persistent hypoesthesia (&lt;i&gt;n&lt;/i&gt;=3), and chronic pain (&lt;i&gt;n&lt;/i&gt;=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 (&lt;i&gt;P&lt;/i&gt;&lt;0.05).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The anterolateral thigh-ilioinguinal Flow-through flaps for repairing complex lower limb injuries is a good method.
