The analysis encompassed technical developments, surgical protocols, combination therapies, regenerative mechanisms, and clinical outcomes.</p><p><strong>Results: </strong>Diabetic foot is one of the most severe complications of diabetes mellitus. Conventional treatments show limited efficacy in patients with advanced stages, such as Wagner grade 3/4 or Texas grade C and above. TTT, an evolution of the Ilizarov technique, promotes tissue regeneration through the \"tension-stress principle\". The procedure for the treatment of diabetic foot has evolved from an open large cortical window (120 mm×20 mm) to a minimally invasive small window (50 mm×15 mm), with incision length reduced to 10 mm and simplified external fixators. A dual-incision technique (10 mm apart) is now applied at 5 cm distal to the tibial tuberosity. Bone transport typically begins 3-5 days postoperatively at a rate of 1 mm/day, incorporating the \"accordion technique\" (2 weeks distraction+3 days stabilization+reverse transport). Multicenter studies report a limb salvage rate of 96.1%, wound healing rate of 96.3%, and amputation rate of less than 5%. Combining TTT with vascular reconstruction and antibiotic-loaded bone cement further enhances outcomes. There are also a series of studies on the mechanism of TTT in treating diabetic foot. TTT has been shown to activate the hypoxia-inducible factor 1α-vascular endothelial growth factor/stromal cell-derived factor 1 (HIF-1α-VEGF/SDF-1) signaling pathway to facilitate microcirculatory reconstruction; mobilize immune cells and rebalance macrophage polarization, thereby improving the inflammatory microenvironment; recruit stem cells via chemotaxis to accelerate re-epithelialization; and promote the release of regenerative small extracellular vesicles.</p><p><strong>Conclusion: </strong>TTT demonstrates promising clinical potential in the treatment of diabetic foot, particularly in improving limb perfusion and promoting tissue repair. However, the underlying mechanisms have not been fully elucidated. Further in-depth investigations are required.

There were 6 males and 5 females, aged 21-60 years with an average of 43.2 years. Among them, 5 cases were untreated congenital rigid clubfoot, 4 cases were recurrent rigid clubfoot after previous treatment, and 2 cases were rigid clubfoot due to disease sequelae. All 11 patients first received slow distraction using Ilizarov technique combined with circular external fixator until the force lines of the foot and ankle joint were basically normal. Then, 1 male patient aged 24 years was selected, and CT scanning was used to obtain imaging data of the ankle joint and foot. A 3D finite element model was established and validated using the plantar stress distribution nephogram of the patient. After validation, the biomechanical changes of the tibiotalar joint under the same load were simulated after triple arthrodesis and fixation. The optimal correction angle of the hindfoot was determined to fabricate 3D-printed osteotomy guide plates, and all 11 patients underwent triple arthrodesis using these guide plates. The functional recovery was evaluated by comparing the American Orthopaedic Foot and Ankle Society (AOFAS) score, International Clubfoot Study Group (ICFSG) score, and 36-Item Short Form Survey (SF-36) score before and after operation.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Finite element analysis showed that the maximum peak von Mises stress of the tibiotalar joint was at hindfoot varus 3° and the minimum at valgus 6°; the maximum peak von Mises stress of the 3 naviculocuneiform joints under various conditions appeared at lateral naviculocuneiform joint before operation, and the minimum appeared at lateral naviculocuneiform joint at neutral position 0°; the maximum peak von Mises stress of the 5 tarsometatarsal joints under various conditions appeared at the 2nd tarsometatarsal joint at hindfoot neutral position 0°, and the minimum appeared at the 1st tarsometatarsal joint at valgus 6°. Clinical application results showed that the characteristics of clubfoot deformity observed during operation were consistent with the preoperative 3D reconstruction model. All 11 patients were followed up 8-24 months with an average of 13.1 months. One patient had postoperative incision exudation, which healed after dressing change; the remaining patients had good incision healing.

There were 40 patients with distal clavicle fractures (fracture group) and 50 with acromioclavicular joint dislocations (dislocation group).

There was 1 male and 5 females with an average age of 28.7 years (range, 20-49 years). There were 3 cases of simple ankle equinus, 2 cases of ankle equinus, midfoot rocker-bottom foot, and forefoot pronation, and 1 case of calcaneus foot and forefoot pronation. Preoperative American Orthopedic Foot and Ankle Society (AOFAS) score was 45.3±18.2, 12-Item Short-Form Health Survey (SF-12)-Physical Component Summary (PCS) score was 34.3±7.3 and Mental Component Summary (MCS) score was 50.4±8.8. Imaging examination showed tibial-calcaneal angle of (79.8±31.5)°, calcaneus-first metatarsal angle of (154.5±45.3)°, talus-first metatarsal angle of (-19.3±35.0)°. Except for 1 case with severe deformity that could not be measured, the remaining 5 cases had talus-second metatarsal angle of (40.6±16.4)°. The deformities were fixed with TSF after soft tissue release and osteotomy. Then, the residual deformities were gradually corrected according to software-calculated prescriptions. TSF was removed after maximum deformity correction and osteotomy healing. External fixation time, brace wearing time after removing the TSF, and pin tract infection occurrence were recorded. Infection severity was evaluated based on Checketts-Otterburns grading. Joint function was evaluated using AOFAS score and SF-12 PCS and MCS scores. Patient satisfaction was assessed using Likert score. Imaging follow-up measured relevant indicators to evaluate the degree of deformity correction. Deformity recurrence was observed during follow-up.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The external fixation time was 103-268 days (mean, 193.5 days). The mild pin tract infections occurred during external fixation in all patients, which healed after pin tract care and oral antibiotics. No serious complication such as osteomyelitis, fractures, neurovascular injury, or skin necrosis occurred. After external fixation removal, 3 cases did not wear braces, while the remaining 3 cases wore braces continuously for 6 weeks, 8 weeks, and 3 years, respectively. All patients were followed up 13.9-70.0 months, with an average of 41.7 months. During follow-up, none of the 6 patients had recurrence of foot deformity. At 1 year after operation, the AOFAS score was 70.0±18.1, SF-12-PCS and MCS scores were 48.9±4.5 and 58.8±6.4, respectively, all showing significant improvement compared to preoperative values ( &lt;i&gt;P&lt;/i&gt;&lt;0.05).
