Abstract Background “Orthoplastics” is a relatively new approach to lower limb reconstruction, where an integration of both plastic and orthopedic expertise is required, together with the availability of well-equipped facilities. Acute shortening and long-term frames for lengthening are generally considered alternatives to length preservation and soft tissue microsurgical reconstruction, but an integration of external fixation and reconstructive microsurgery is gaining an increasing role with refinements of joint approaches. Material and methods Data on sixteen patients who underwent microsurgical lower limb reconstruction and external fixation with an orthoplastic approach, following acute or chronic tibial injury, were retrospectively reviewed. All patients presented a post traumatic soft tissue defect associated with a Gustilo III tibial fracture or a tibial septic pseudarthrosis. Data on type and timing of bone and soft tissue reconstruction, outcomes, complications and need for re-operation were extrapolated and compared to an historic group of patients treated with an orthopedic-based approach. Results In the orthoplastic group, soft tissues were reconstructed with an ALT flap in most cases; a muscle-sparing VL or ALT-VL chimeric flap was necessary in cases with a very extensive defect. In the orthopedic group, soft tissues were left to heal by second intention or patients were lately referred to plastic surgeons. Statistical comparison between the two groups has showed significant differences on the following data: time for soft tissue healing, time to bone union, number of reinterventions, post-operative deep infection rate, time to return to work. Conclusion The orthoplastic approach to complex leg defects yields shorter treatment time and better functional results compared to the orthopedic-based approach. External fixation and microsurgical reconstruction are not necessarily alternative procedures but can integrate in an orthoplastic path to address at best both soft tissue and bone reconstruction.

Introduction: Tactic of emergency closing of soft tissue defect allows to significantly improve the treatment results concerning patients with severe open fractures. However, a number of certain factors make the implementation of this tactic rather difficult. Injured people’s unstable conditions are mong these crucial factors which include, polytrauma in lots of cases, absence of exact recommendations for recovery terms, choice of definite tissue flaps and a type of circulation. The Aim of Study: is to develop exact, usable and in practice algorithm of emergency reconstruction of leg soft tissues in patients with severe open tibia fractures, based on the usage of the most foolproof and simple methods. Data (Patients) and Methods: 85 patients with open tibia fractures complicated by soft tissue defects were included in our study. Patients were divided into two groups. The control group consisted of 56 patients. Soft tissue reconstruction in this group was provided without an exact algorithm, after continuous attempts on local healing. After analyzing the treatment process and the treatment results we have developed the algorithm of emergency soft tissue reconstruction. It was used in 29 patients (the study group). This algorithm allows choosing optimal timing for tissue reconstruction and appropriate method to be applied, depending on the patient’s condition, the mechanism of soft tissue defect formation, and its square and localization. Results: We observed a statistical decrease in deep wound infection frequency, partial tibia necrosis frequency, chronic osteomyelitis frequency, duration of hospitalization in patients with severe open tibia fractures because of using our algorithm.

AbstractSoft tissue defects of the lower extremity that expose underlying bones, joints, and tendons pose challenging problems and generally require free tissue transfer for a successful reconstruction. Historically, muscle flaps were the gold standard choice for lower limb reconstruction. To obviate the unpredictable appearance and high donor-site morbidity of muscle flaps, fasciocutaneous flaps were introduced. Recently, perforator flaps, such as the anterolateral thigh flap, gained a leading role in the reconstructive scenario. There is growing evidence in the literature supporting that fasciocutaneous and perforator flaps are comparable to muscle flaps in terms of flap survival, postoperative infection, osteomyelitis, bone union, and ambulation. With the advances of knowledge in perforator anatomy and their mapping, a new era of lower limb reconstruction has begun. Propeller flap could be raised on any suitable perforator vessel and, without the aid of microsurgical anastomosis, used to restore small- to middle-sized soft tissue defects. In this review, we intend to analyze pros and cons of muscle and fasciocutaneous free flaps and the applicability of the propeller flaps in lower limb reconstruction.

Introduction: Free tissue transfers have become a mainstay in lower limb salvage, allowing safe and reliable reconstruction after trauma, tumor extirpation, and complex wounds. The optimal perioperative (PO) management of these flaps remains controversial. This study aims to assess the current state of practice among Canadian microsurgeons. Methods: Sixty-four Canadian microsurgeons were approached to complete an online questionnaire regarding their PO management of fasciocutaneous free flaps used for lower limb reconstruction. Trends in dangling timing and duration, use of venous couplers, compressive garments, thromboprophylaxis, and surgeons’ satisfaction with their protocol were assessed. Results: Twenty-eight surgeons responded. Fifty-seven percent did not have a specific mobilization protocol. Dangling was mainly initiated on postoperative days 5 to 6 (44%). The most common protocol duration was 5 to 6 days (43%). The concern for prolonged venous pooling was the main reason for delay of dangling (71%). Compressive garments were placed routinely by 12 surgeons (43%) with 20% starting before dangling, 46% with dangling, and 33% after dangling. Venous couplers were routinely used by 24 surgeons (85.7%). Trends in management were influenced by previous training in 53.6% of cases (vs evidence-based medicine 7.1%). Although 89.3% were satisfied with their approach, 92.8% would consider changing practice if higher-level evidence was available. Conclusions: The majority of Canadian microsurgeons initiate dangling early and utilize venous couplers. However, the use of compressive garments is limited. Trends in management are largely based on personal experience. Nearly all surgeons would consider changing their practice if higher-level evidence was available.

Soft tissue losses from tumor removal, trauma, aging, and congenital malformation affect millions of people each year. Existing options for soft tissue restoration have several drawbacks: Surgical options such as the use of autologous tissue flaps lead to donor site defects, prosthetic implants are prone to foreign body response leading to fibrosis, and fat grafting and dermal fillers are limited to small-volume defects and only provide transient volume restoration. In addition, large-volume fat grafting and other tissue-engineering attempts are hampered by poor vascular ingrowth. Currently, there are no off-the-shelf materials that can fill the volume lost in soft tissue defects while promoting early angiogenesis. Here, we report a nanofiber-hydrogel composite that addresses these issues. By incorporating interfacial bonding between electrospun poly(ε-caprolactone) fibers and a hyaluronic acid hydrogel network, we generated a composite that mimics the microarchitecture and mechanical properties of soft tissue extracellular matrix. Upon subcutaneous injection in a rat model, this composite permitted infiltration of host macrophages and conditioned them into the pro-regenerative phenotype. By secreting pro-angiogenic cytokines and growth factors, these polarized macrophages enabled gradual remodeling and replacement of the composite with vascularized soft tissue. Such host cell infiltration and angiogenesis were also observed in a rabbit model for repairing a soft tissue defect filled with the composite. This injectable nanofiber-hydrogel composite augments native tissue regenerative responses, thus enabling durable soft tissue restoration outcomes.

Introduction: Major crush injury of elbow joint following trauma with extensive injury to skin & soft tissue, bone, tendon, nerves and vessels remains a challenge to the reconstructive surgeon. Purpose of this study is to nd out whether the size of the defect, type of ap used and the location of the soft tissue defect inuence the outcome of soft tissue reconstruction. Material and methods: A prospective study was performed in all patients with soft tissue defects around the elbow in need of ap cover at Ganga Medical Centre Coimbatore, Tamilnadu India from April 2014 to December 2015.Patients demographics, defect size, location, type of ap used, complications and long – term outcomes analysed. Patients Mayo elbow performance score and Likert scale score were recorded for analysis of functional and aesthetic outcome respectively. The Kruskal wallis test was used for statistical comparison. Results: Forty three aps were performed primarily for coverage in forty patients. Three patients required two primary aps for reconstruction. The aps used in our study included 14 local fasciocutaneous aps (32.5%); 20 pedicled aps both locoregional and distant (46.5%) and 9 2 2 Anterolateral thigh free aps (20.9%) The average defect size was 151 cm . For local fasciocutaneous ap the average defect size was 44.7cm , 2 2 2 2 2 (range, 4-120 cm ), distant pedicled ap was181 cm (range 24- 600 cm ) and for the ALT free ap was 252.2 cm (range 80-450 cm ). Conclusion: The defect size is the main determinant of the type of ap used and their outcomes.
