Complex post-traumatic injuries of the extremities remain a major reconstructive challenge because they may simultaneously involve skin, soft tissues, muscle, tendons, nerves, blood vessels, joints, and bone. The objective of this study was to analyze the principal reconstructive strategies used in severe extremity trauma and to determine their relationship with limb preservation, functional recovery, complication reduction, donor-site morbidity, and aesthetic integration. An integrative literature review with a comparative analytical approach was conducted according to the principles of the Scientific Method. Evidence concerning reconstructive timing, orthoplastic management, muscle and fasciocutaneous flaps, free-tissue transfer, limb salvage, functional outcomes, rehabilitation, and aesthetic results was identified and comparatively analyzed. The findings showed that early definitive soft-tissue coverage was associated with lower rates of flap failure and infection, although contemporary evidence supports an individualized therapeutic window according to wound condition and patient stability. Muscle and fasciocutaneous free flaps demonstrated broadly comparable outcomes for infection, revision surgery, and limb salvage, while fasciocutaneous flaps showed advantages in selected outcomes related to donor-site morbidity and flap loss. Overall flap survival and limb-salvage rates were high, frequently exceeding 90%; however, functional recovery was less uniform, demonstrating that technical success does not necessarily correspond to complete restoration of pre-injury function. Aesthetic satisfaction, contour, tissue thickness, scar characteristics, donor-site effects, and social reintegration also emerged as relevant components of long-term outcome. The evidence supports an early, individualized, defect-oriented, multidisciplinary, and patient-centered orthoplastic approach. Contemporary extremity reconstruction should therefore be evaluated according to its capacity to restore a viable, stable, durable, functional, and aesthetically integrated limb rather than by flap survival alone.

Traumatic peripheral nerve injuries of the extremities represent a significant cause of motor, sensory, and functional impairment, particularly when diagnosis or reconstructive management is delayed. This study analyzed the role of neurophysiological assessment and functional reconstruction in the management of traumatic peripheral nerve injuries through an integrative review of clinical and surgical evidence. The analysis focused on mechanisms of nerve injury, clinical examination, nerve conduction studies, needle electromyography, peripheral nerve ultrasound, magnetic resonance neurography, timing of intervention, direct nerve repair, nerve grafting, nerve transfers, and rehabilitation. The findings showed that clinical and neurophysiological assessment constituted the most frequently represented diagnostic components, while imaging provided complementary structural information regarding nerve continuity, neuroma formation, compression, and fascicular abnormalities. Regarding reconstruction, nerve grafting, direct repair, and nerve transfer were the most commonly addressed strategies. Injury severity, anatomical level, timing of intervention, regenerative distance, evidence of reinnervation, and target-muscle condition emerged as the principal factors associated with reconstructive decision-making and functional prognosis. The evidence indicates that no isolated diagnostic modality or surgical technique is sufficient for all traumatic nerve injuries. Instead, serial neurological examination, appropriately timed electrodiagnostic testing, complementary imaging, and individualized reconstructive planning should be integrated within the same therapeutic pathway. Early recognition of severe lesions and timely referral for reconstruction may preserve opportunities for motor and sensory recovery before prolonged denervation compromises the biological capacity of the target tissues. Functional rehabilitation remains essential for translating neural regeneration into useful movement, sensation, and independence.

Lymphedema is a chronic and progressive disorder resulting from impaired lymphatic transport, leading to fluid accumulation, chronic inflammation, fibrosis, and progressive functional impairment. Recent advances in reconstructive surgery have shifted therapeutic strategies from symptom control toward physiological restoration of lymphatic drainage through supermicrosurgical techniques. This review analyzes the current scientific evidence regarding supermicrosurgery and lymphatic reconstruction, emphasizing lymphaticovenous anastomosis, vascularized lymph node transfer, immediate lymphatic reconstruction, advanced diagnostic imaging, and emerging regenerative medicine approaches. Contemporary literature demonstrates that individualized patient selection, supported by indocyanine green lymphography and other imaging modalities, is fundamental for optimizing surgical outcomes. Physiological reconstruction has been associated with reductions in limb volume, lower incidence of cellulitis, improved functional recovery, decreased dependence on compression therapy, and better quality of life when integrated into multidisciplinary care. Emerging technologies, including tissue engineering, therapeutic lymphangiogenesis, artificial intelligence, and image-guided surgery, are expanding future therapeutic possibilities while promoting increasingly personalized treatment strategies. Although current evidence supports the effectiveness of physiological lymphatic reconstruction, further multicenter prospective studies with standardized methodologies are required to strengthen clinical recommendations and improve the global implementation of these techniques. Overall, supermicrosurgery represents a major milestone in modern reconstructive surgery and continues to redefine the management of primary and secondary lymphedema through innovation, technological development, and international multidisciplinary collaboration.

Tissue bioengineering and regenerative aesthetic medicine have emerged as rapidly evolving interdisciplinary fields that integrate plastic surgery, regenerative medicine, endocrinology, molecular biology, biomaterials science, and biomedical engineering to promote tissue restoration and functional recovery. The objective of this review was to analyze current advances in regenerative technologies and their applications in aesthetic and reconstructive medicine. A comprehensive review of scientific literature indexed in major biomedical databases was conducted, focusing on stem cell therapies, platelet-rich plasma, extracellular vesicles, bioactive scaffolds, biomaterials, and three-dimensional bioprinting. The analyzed evidence demonstrated that adipose-derived stem cells and platelet-rich plasma remain the most established regenerative interventions due to their favorable safety profiles, accessibility, and demonstrated effectiveness in tissue repair and rejuvenation. Emerging technologies such as exosome-based therapies and advanced tissue-engineering platforms exhibited significant innovation potential and may contribute to future therapeutic developments. Angiogenesis, extracellular matrix remodeling, cellular signaling, and endocrine regulation were identified as essential mechanisms underlying successful regenerative outcomes. Furthermore, the findings highlighted the increasing importance of personalized regenerative approaches that incorporate metabolic and hormonal optimization. Despite substantial progress, challenges related to protocol standardization, long-term clinical validation, regulatory frameworks, and accessibility remain significant barriers to widespread implementation. Overall, tissue bioengineering and regenerative aesthetic medicine represent promising strategies capable of transforming contemporary healthcare by promoting biological restoration, improving aesthetic outcomes, and advancing personalized therapeutic interventions.
