[A case of repairing the destructive high-voltage electric burn wounds in the head, face, and neck based on the economic theory of flaps].

In September 8th, 2021, a male patient (aged 18 years) with severe destructive injuries of high-voltage electric burns in the head, face, and neck was admitted to General Hospital of Taiyuan Iron Steel (Group) Co., Ltd. Based on the economic theory of flaps, the flap donor site and transplantation method were optimized and evaluated before surgery, and then debridement of head, face, and neck wounds+removal of necrotic skull+free transplantation of super large latissimus dorsi myocutaneous flap+thin intermediate thickness skin graft transplantation from the left thigh was performed. The extra large flap donor site wound was sutured directly. This surgery reduced the adverse consequences of the flap donor site on the premise of ensure of repair effect. After operation, the patient's condition was stable, the flap and skin graft survived well, the repair effect of wound was well, the scar in the flap donor area was relatively mild, and the upper limb had no dysfunction.

Introducing the Muzzammil classification for spoke wheel injuries in children to enhance injury assessment and treatment in developing countries.

Motorbike spoke wheel injuries (SWIs) among children are a notable public health concern, especially in low and middle-income regions. The primary objective of this study is to comprehensively examine the patterns of motorbike spoke wheel injuries (SWIs) in children. Additionally, the study introduces a novel classification system for these injuries. The implementation of this classification system aims to streamline the management of SWIs, making it more efficient and facilitating the development of standardized treatment protocols. This prospective observational study was conducted in the Accident and Emergency Department from January 2019 to 2021. Children < 14 years of age of either gender with foot and ankle injury due to motorbike spoke wheels as passengers and presenting within 3 days were included. The motorbike SWI was assessed for its location and classified by a new classification as Class I, Soft tissue injury without skin loss; Class II, Skin loss of more than 1 cm without underlying tissue involvement; Class III, Skin loss with underlying tissue involvement, this class is further divided on basis of underlying soft-tissue involvement; Class IV: mangled foot/toe. Management plan and outcome were noted. In our study158 children suffering from SWI were registered with a mean age of 6.2 ± 5.4 years, 127 (80.37%) males and 31 (19.62%) females. Class I injury was seen in 18 (11.39%) patients, class II in 69 (43.67%), and class III in 68 (43.03%) patients. Class III injuries were further subcategorized as follows: IIIT (Tendon) injuries, which accounted for 32 cases (20.25%); IIIB (Bone) injuries, with 29 cases (18.35%); and IIINV (Neurovascular) injuries, identified in 7 cases (4.43%). Class IV injuries were observed in 3 (1.8%) children. The flap was needed in 33 (20.88%) patients. There were no complications like flap necrosis or graft rejection. In this current study, a new classification system specific for a motorbike SWI has been introduced along with its application on children presenting at tertiary care hospital's emergency department. The application of the proposed classification will enable universal management guidelines for SWIs, especially in the Ino-Pak region where SWIs are common.

ATMP-classified, scalable, autologous cell spray for the treatment of skin wounds and assessment of its effects on wound healing clinically and on a molecular level.

BACKGROUND: Autologous split-thickness skin grafts (STSGs) are the standard of care for closure of deep and large burns. However, perforation and extensive fishnet-like expansion of the grafts to achieve greater area wound coverage can lead to treatment failures or esthetically poor healing outcomes and scarring. The purpose of this study was to validate an autologous advanced therapy medicinal product (ATMP)-compliant skin cell suspension and evaluate its efficacy to promote epithelialization. METHODS: Cells isolated from a piece of STSG according to ATMP classification requirements were sprayed onto 20 patients during a single operation in a validation study. Comparative evaluation of treatment efficacy was carried out using side-by-side skin graft donor site wounds that were standardized in depth. Firstly, we characterized wound healing transcriptomes at 14 and 21 days from serial wound biopsies in seven patients. Then, side-by-side wounds in four patients were treated with or without the skin cells. The wounds were photographed, clinical outcomes assessed, and the treatment and control wound transcriptomes at 14 days were compared to the untreated wounds' healing transcriptomes. RESULTS: The average cell yield after isolation from the STSG was 2.4 × 106 cells/cm2 with 96 % viability. The product contained mainly keratinocytes and their precursors but also other skin cells such as fibroblasts were present. As compared to vehicle-treated donor site wounds, the wounds treated with cells demonstrated improved epithelialization by both direct comparison and machine learning analysis of the transcriptomes. CONCLUSIONS: We showed that rapid and scalable ATMP-classified processing of skin cells is feasible, and application of the skin cells effectively promotes healing and epithelization of donor site wounds.

Synchronous circular frame stabilisation and microsurgical soft tissue reconstruction for open lower limb fractures-A cost analysis and description of the surgical technique.

INTRODUCTION: Current surgical paradigms for ortho-plastic management of IIIB open tibial fractures make compromises. Often, definitive circular frame stabilisation is delayed until the soft tissue envelope is secure to allow access for further soft tissue reconstruction if required. This delay has potential clinical and cost implications. A previous study showed acute circular frame stabilisation performed concurrently or before soft tissue reconstruction was feasible without additional soft tissue reconstruction problems. This study examines potential resource savings using this approach. METHODS: All open tibial fractures managed by circular fixator and microsurgical soft tissue reconstruction between April 2015 and June 2019 were identified from a prospectively maintained database. Those receiving circular frame stabilisation with synchronous microsurgical soft tissue reconstruction were considered cases; those in whom the frame stabilisation was delayed were controls. Cost data were derived from the Patient Level Information and Costing System. Salvage cases and those with incomplete treatment were excluded. RESULTS: Nine cases and 25 controls were evaluated. No statistically significant difference was observed between groups in terms of age, sex, injury severity score, time to debridement, time to coverage, length of follow up, or time to union. Median length of stay was 13.3 and 19.7 days for cases and controls respectively (p<0.01). Cases required fewer procedures (2.3) compared to controls (4.5) (p<0.001). The cost of care was less for cases (£25,527) than controls (£32,952) (p <0.05). No cases returned to theatre with flap failure or flap compromise. Complications were similar between groups. CONCLUSION: In suitable patients, synchronous circular frame stabilisation and microsurgical soft tissue reconstruction is a safe, clinically effective, and cost-saving option.

Wound-Healing Following Negative-Pressure Wound Therapy with Use of a Locally Developed AquaVac System as Compared with the Vacuum-Assisted Closure (VAC) System.

BACKGROUND: Negative-pressure wound therapy (NPWT) gained widespread clinical use after its introduction in the 1990s because of its many beneficial effects on the wound environment. However, high treatment costs have limited its use in third-world countries. The present study compares a low-cost, locally developed NPWT system with a commercially available system in terms of efficacy, reliability, ease of application, and safety. METHODS: This prospective, randomized controlled trial involved 36 patients who were managed with NPWT with either a low-cost, locally developed system (AquaVac) or a commercially available Vacuum-Assisted Closure Advanced Therapy System (VAC ATS; KCI). The low-cost NPWT system described consists of a converted aquarium pump as a reusable vacuum source and a dressing system that can be found in the hospital supply room: food plastic wrap as an occlusive drape, surgical gauze as wound filler, nasogastric tubes as tubing, and used intravenous (IV) bottles as effluent canisters. The purpose of the study was to compare the 2 systems in terms of (1) time to apply the dressing, (2) exudate levels, (3) amount of granulation tissue, (4) wound size reduction, (5) average cost of treatment, (6) visual analog scale (VAS) pain scores, and (7) complications. RESULTS: The experimental low-cost system had a small but statistically insignificant advantage over the commercially available system in terms of application time, pain during dressing changes, and wound contraction percentage. The 2 systems were comparable in terms of the amount of exudate, granulation tissue coverage, and VAS scores during the course of treatment. No wound or periwound complications were observed. The systems were significantly different in terms of cost, with the AquaVac system being 7 times less expensive than the VAC ATS system ($63.75 compared with $491.38 USD). CONCLUSIONS: The low-cost AquaVac system was shown to be comparable with the commercial VAC ATS system, suggesting that it is an effective and safe alternative method for NPWT in resource-challenged settings. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Free perforator flaps vs propeller flaps in lower limb reconstruction: A cost/effectiveness analysis on a series of 179 cases.

PURPOSE: The aim of this report is to compare free perforator flaps and propeller flaps in the coverage of lower limb soft tissue defects. PATIENTS AND METHODS: 179 patients (age between 5 and 92 years old), underwent soft tissue reconstruction of the lower limb between January 2009 and January 2015, either by free flap or propeller flap. The two groups were retrospectively evaluated in order to assess the outcome, complications and potential risk factors. Correlations between risk factors and presence/absence of failure or complications have been evaluated with descriptive statistical analysis and a set of logistic regression models. Finally, an economic analysis was conducted to evaluate the different tecniques. RESULTS: In a simple descriptive statistical analysis, the overall failure rate is 6% for free flaps and 3.7% for propeller flaps; the complication rates are 14% vs 21.5% and it increases as dimension increases. The logistic models relating failure and complications with potential risk factors do not show significant differences, whereas the economic analysis show that the average expense of free flaps is 5077.5€ per patient, 1595.6€ per patient for propeller flaps. CONCLUSIONS: Our results do not demonstrate significant differences between the two groups about correlation of risk factors or flap size with complication or failure. The surgical option choice should be taken only after accurate evaluation of the soft tissue surrounding the defect. Propeller flaps should be preferred in case of small/medium size defects in otherwise healthy extremities. Free perforator flaps should be the choice in large defects due to trauma or vascular diseases. The economic analysis suggests that propeller flap should be considered when possible.

Immediate Reconstruction of Oncologic Spinal Wounds Is Cost-Effective Compared with Conventional Primary Wound Closure.

BACKGROUND: Several studies have demonstrated a reduced wound complication rate when immediate soft-tissue reconstruction is performed after complex spine instrumentations in high-risk patients; however, the cost-effectiveness of this technique is not known. The authors hypothesized that immediate soft-tissue reconstruction of oncologic spine wounds would be a cost-effective strategy compared with the standard of care (i.e., oncologic spine surgery with conventional primary wound closure). METHODS: The authors used a decision tree model to evaluate the cost-utility, from the perspective of a hospital/insurer, of immediate reconstruction relative to the standard of care after oncologic spine surgery. A systematic review of the literature on oncologic spine surgery and immediate and delayed spinal wound reconstruction was performed to estimate health state probabilities. Overall expected cost and quality-adjusted life-years were assessed using a Monte Carlo simulation and sensitivity analyses. RESULTS: Immediate soft-tissue reconstruction after oncologic spine surgery had an expected cost of $81,458.90 and an expected average of 24.19 quality-adjusted life-years, whereas primary wound closure (no reconstruction) had an expected cost of $83,434.34 and an expected average of 24.17 quality-adjusted life-years, making immediate reconstruction the dominant, most cost-effective strategy. Monte Carlo sensitivity analysis demonstrated that immediate reconstruction was the preferred and most cost-effective option in the majority of simulations. Even when the willingness-to-pay threshold varied from $0 to $100,000 per quality-adjusted life-year, immediate reconstruction remained the dominant strategy across all iterations. CONCLUSION: This cost-utility analysis suggests that immediate soft-tissue reconstruction after oncologic spine surgery is more cost-effective than primary closure alone.

Preoperative Diagnosis Can Predict Conversion Total Knee Arthroplasty Outcomes.

BACKGROUND: Compared to total knee arthroplasty (TKA) for primary osteoarthritis, conversion TKAs in the post-traumatic setting are associated with increased operative times, infection rates, and readmissions. We aim at determining how post-traumatic osteoarthritis and previous knee surgery influence postoperative outcomes in conversion TKA. METHODS: Seventy-two conversion TKA procedures with prior knee trauma at a single institution between April 2012 and 2016 were examined. Twenty-seven (37.5%) cases had a preoperative site-specific diagnosis such as fracture of the proximal tibia, distal femur, or patella whereas 45 (62.5%) cases had a preoperative diagnosis of significant soft-tissue trauma. These 2 groups were compared in terms of total implant cost, length of stay, complications, and readmission and reoperation rates. A subanalysis was conducted to evaluate the effects of previous knee surgery on surgical outcomes. RESULTS: The postfracture TKA cohort suffered significantly higher early surgical site complications (22% vs 4.4%, P = .02) and 90-day readmissions (14.8% vs 2.2%, P = .042) compared to the soft-tissue trauma cohort. Operative time, total implant costs, length of stay, medical complications, 30-day readmissions, and 90-day reoperation rates did not significantly differ. It was also found that patients with multiple prior knee surgeries compared to one prior knee surgery are younger (53.0 vs 63.1, P = .003), healthier, and receive significantly more expensive implants (1.72 vs 1.07, P = .026). In addition, patients with previous open reduction internal fixations experience more surgical site complications than patients with previous arthroscopies (31% vs 3.3%, P = .042). CONCLUSION: Patients with previous site-specific fracture are more likely to experience surgical site complications and 90-day readmissions after conversion TKA than patients with previous soft-tissue knee trauma. Multiple previous knee surgeries appear to serve as an independent factor in the selection of costlier implants irrespective of preoperative diagnosis.

A representative assessment of the management of open fractures of the lower limb within UK orthoplastic centres: A two-centre audit of compliance with national standards.

BACKGROUND: Open fractures of the lower limb represent a complex and varied array of injuries. The BOAST 4 document produced by BAPRAS and the BOA provides standards on how to manage these patients, and NICE have recently produced additional guidance. We aimed to assess concordance with these standards in a large cohort representative of UK orthoplastic centres. METHODS: Patients admitted to the orthoplastic units at Norfolk and Norwich University Hospital and Royal Stoke University Hospital with open lower limb fractures between 2009 and 2014 were included. Data was gathered from notes and endpoints based on the BOAST 4 document. RESULTS: In total, 84 patients were included across the two sites, with 83 having their initial debridement within 24h (98.8%). Forty-two patients had a documented out-of-hours initial surgery. Of these, 10 (23.8%) had an indication for urgent surgery. This pattern was consistent across both hospitals. A plastic surgeon was present at 33.3% of initial operations. Of 78 patients receiving definitive soft tissue cover, 56.4% had cover within 72h and 78.2% within 7days. Main reasons for missing these targets were transfer from other hospitals, plastic surgeons not present at initial operation and intervening critical illness. CONCLUSIONS: This study has identified key areas for improving compliance with the national BOAST 4 and NICE standards. Out-of-hours operating is occurring unnecessarily and time targets are being missed. The development of dedicated referral pathways and a true orthoplastic approach are required to improve the management of this complex set of injuries.

Setting the Goals in the Management of Mutilated Injuries of the Hand-Impressions Based on the Ganga Hospital Experience.

Mutilated injuries need to be treated aggressively and appropriately to avoid amputation or severe disability in the individual. Assessment of the management of these injuries on a global level reveals that there is a gap between the need and availability of the skilled manpower to manage these injuries. There is also a gap in the utilization of the available services. These gaps need to be covered or narrowed as far as possible. Although some measures need policy changes and improvement of health care delivery infrastructure, simpler measures taken at the final health care delivery level can significantly improve the final outcome.

A prospective randomized cost billing comparison of local fasciocutaneous perforator versus free Gracilis flap reconstruction for lower limb in a developing economy.

UNLABELLED: Distal half leg complex wounds are usually a formidable problem that necessitates either local or free flap coverage. The aim of this study was to compare cost billing charges in free Gracilis flap (fGF) and local fasciocutaneous perforator flap (lFPF) in reconstructing complex soft tissue leg and foot defects. PATIENTS AND METHODS: Thirty consecutive adult (>15-year-old) patients with soft tissue defects in the leg and/or foot requiring tissue coverage with a flap in the period between 2012 and 2015 were randomly assigned (block randomization) to either an fGF or lFPF procedure. The outcome measures addressed were total billed charges costs, perioperative billed charges cost, partial or complete flap loss, length of hospital stay, inpatient postsurgical care duration, complications, operating time and number of operative scrub staff. RESULTS: One patient suffered from complete flap loss in each group. Reconstruction with lFPF showed total lower billed charges costs by 62% (2509 USD) (p < 0.001) and perioperative billed charges cost by 54% (779 USD) (p < 0.001), and shorter total hospital stay (36.5 days; p < 0.001), inpatient postsurgical care duration (6.4 days; p < 0.001), operating time (4.3 h; p < 0.001) and fewer scrub staff (2.2 persons; p < 0.001). CONCLUSION: These results suggest that neither flap is totally superior to the other; the choice should instead be based on the outcome sought and logistics. lFPF requires lower billed charges cost and resource use and saves operative time and personnel and reduces length of hospital stay. Our approach changed towards using perforator flaps in medium-sized defects, keeping the free flap option for larger defects.

Hand amputations: epidemiology, management and resurfacing options for soft tissue coverage.

OBJECTIVE: Agricultural hand injuries occur mainly among young adults, many affecting the dominant hand, thereby impeding patients' ability to work or cope with social obligations. This study was carried out with the aim of collecting data on the epidemiology and management of agricultural hand injuries in Indian subjects. METHOD: The study was conducted in the Department of Plastic and Reconstructive Surgery, JN Medical College, AMU, Aligarh, India, from October 2009 to December 2013. Patients with agricultural hand injuries were included. Data collected included socio-demographic details, mode and type of injury, type of reconstruction, complications, length of hospital stay and assessment of post-reconstruction status. These data were tabulated and analysed. RESULTS: The typical patient was young (mean 33.2 years), of lower socio-economic status and with a total disregard for safety regulations. There is clustering of cases during the wheat harvest season (April-June). Wheat thresher injuries were the most common cause of partial hand amputation (51%), especially during this season. This was followed by fodder cutting (kutti/chara) machine injury, especially in females and children (36%). A simple classification for these injuries has been described and Grade II injury was the commonest. Reverse radial forearm flap was the most suitable regional flap for coverage, whereas thoraco-umbilical flap was the most commonly used distant flap. Patients who had the single-stage procedure had a significantly shorter stay. CONCLUSION: Agricultural hand injuries are not totally avoidable and their incidence can be reduced by proper education, but the low economic and literacy status of the patients is a big hurdle. The forearm offers many flaps for reconstruction of hand, which can be used in defects on dorsal or palmar aspect of hand and results in early discharge from the hospital and early rehabilitation. In patients with associated injury to the forearm, abdominal flaps can be used for cover.

Soft tissue injury of the shoulder after single non-dislocating trauma: prevalence and spectrum of intraoperative findings during shoulder arthroscopy and treatment results.

BACKGROUND AND PURPOSE: The purpose of our study was to present the spectrum and prevalence of intraarticular lesions in patients with shoulder pain after a single non-dislocating shoulder trauma and to evaluate the clinical results according to pathology and workers' compensation status. METHODS: Sixty consecutive patients (61 shoulders) with shoulder pain following a single non-dislocating shoulder trauma had shoulder arthroscopy. The indication for surgery was either persistent pain for 3 months or longer after trauma and/or an intraarticular lesion on MRI. Patients with history of shoulder complaints, previous shoulder surgery, a complete rotator cuff tear or a fracture of the shoulder girdle were excluded. Intraarticular findings during shoulder arthroscopy were retrospectively analyzed. After a minimum follow-up of 1 year patients were contacted by telephone interview and ASES score, Simple Shoulder Test, Subjective Shoulder Value and residual pain were assessed for the entire population and for patients with and without workers' compensation. RESULTS: The most common intraarticular findings were SLAP (44.3 %) and Pulley (19.7 %) lesions followed by lesions of the anterior or posterior labrum (14.8 %). The mean age of the 13 women and 47 men was 41.9 years (SD 10.9). Patients with workers' compensation had significantly lower scores than patients without and had a significantly lower return to work rate than patients without. INTERPRETATION: In patients with persistent shoulder pain after sprain or contusion arthroscopy revealed a broad spectrum of intraarticular findings. Patients with workers' compensation claims had worse results than those without. LEVEL OF EVIDENCE: Case series (Level IV).

Wound closure of leg fasciotomy: comparison of vacuum-assisted closure versus shoelace technique. A randomised study.

BACKGROUND: Fasciotomies, though essential for the prevention and management of compartment syndromes, may increase morbidity and prolong hospitalisation. Two widely applied methods of delayed primary closure are compared in leg fasciotomy wounds. PATIENTS AND METHODS: Two groups, each of 25 patients with leg fasciotomies due to fractures and soft tissue injuries, who were randomly assigned to be treated either by vacuum assisted closure (VAC®, n=42 wounds, group V) or by the shoelace technique (n=40 wounds, group S), were evaluated in this study. Wound length, time to definite closure, complications, need for additional interventions and daily treatment costs were data collected and statistically assessed. RESULTS: Wound closure time was significantly higher in group V compared to group S (p=0.001; 95% CI of the difference, 1.8-6.3 days). Five group V patients required split thickness skin grafts. In six group S patients, the vessel loops had to be replaced. The mean daily cost of negative pressure therapy alone was 135 euro (range 117-144 euro), whilst the mean daily cost of treatment for the shoelace technique was 14 euro ranging from 8 to 18 euro (p=<0.001). CONCLUSIONS: Both VAC® and the shoelace technique are safe, reliable and effective methods for closure of leg fasciotomy wounds. VAC® requires longer time to definite wound closure and is far more expensive than the shoelace technique, especially when additional skin grafting is required.

Quantitative assessment of bone microvascularization after osteocutaneous flap transplantation using contrast-enhanced ultrasound (CEUS).

BACKGROUND: Extensive wound defects frequently have to be covered by free flap transplantation. A monitoring device for measuring capillary level perfusion of bone is currently not available. OBJECTIVE: The aim of the study was to detect complications after osteocutaneous flap transplantation using contrast-enhanced ultrasound (CEUS). Additionally quantitative analysis was performed by special perfusion software (QONTRAST®; Bracco, Italy). METHODS: 22 patients were examined after osteocutaneous flap transplantation during the first 72 h after operation. CEUS was performed with a linear transducer (6-9 MHz, LOGIQ E9/GE) after bolus injections of 2.4 ml ultrasound contrast agent (SonoVue®; Bracco, Italy). The osseous perfusion and soft tissue perfusion were analyzed separately and quantitative perfusion analysis was performed. Five patients had to undergo reoperation due to compromised flap microvascularization. RESULTS: In all 5 complications reduced osseous and soft tissue perfusion was seen using CEUS. Additionally using the perfusion parameters TTP (time to PEAK), RBV (regional blood volume), RBF (regional blood flow) und MTT (mean transit time), significantly lower soft tissue and osseous perfusion was detected. CONCLUSION: CEUS seems to be capable of detecting vascular disturbances and of assessing microvascularization of the osseous component after osteocutaneous flap transplantation.

The efficacy of color duplex sonography in preoperative assessment of anterolateral thigh flap.

The anterolateral thigh (ALT) flap has become a workhorse in reconstructive surgery of the head and neck region and the extremities. However, its inconsistent vascular anatomy and frequent intramuscular course of perforators often cause difficulties during the dissection of this versatile flap. Hence, reliable preoperative perforator mapping and identification of vascular anomalies may render the raising of the flap easier and safer. The aim of this study was to evaluate the use of Color Duplex sonography and whether it allows the distinction between septocutaneous and musculocutaneous perforators. For this purpose, the thighs of 13 patients undergoing reconstruction with ALT flaps were examined preoperatively, and results were compared to intraoperative findings. A total of 30 perforators could be detected preoperatively, of which 29 were confirmed during flap dissection. Preoperative Color Duplex sonography correctly predicted the course of all perforators as either running through the vastus lateralis muscle or the intermuscular septum. In our investigations, Color Doppler sonography had a 96.7% positive predictive value and a 96.7% true positive rate in detecting perforators. Color Duplex sonography is a highly reliable tool in the preoperative assessment of ALT flaps. Localization and course of perforators can be determined accurately and vascular anomalies can be identified.

A pediatric acute wound service: a novel approach in wound management.

INTRODUCTION: In 2001, in response to an overwhelming increase in patient visits for various pediatric abscesses, burns, and other wounds, an ambulatory burn and procedural sedation program (Pediatric Acute Wound Service, or PAWS) was developed to minimize operating room utilization. The purpose of this study is to report our initial 7-year experience with the PAWS program. METHODS: The hospital records of all children managed through PAWS from 2001 to 2007 were reviewed. Outcomes measured include patient demographics, number and location of visits per patient, procedure information, cause of wounds, and reimbursement. chi(2) test and linear regression were performed using GraphPad Prism (GraphPad Software Inc, San Diego, CA). RESULTS: Overall, 7620 children (age 0-18 years) received wound care through PAWS from 2001 to 2007. There were no differences in patient age, race, and sex during this time period. Between 2001 and 2007, the percentage of patients seen as outpatients increased from 51% to 68% (P < .05), and the average number of visits per patient decreased from 3.9 to 2.4 (P = .05). In, 2007, 46% of the children required only 1 visit. In 2007, 74% of the visits were for management of wound and soft tissue infections, compared with only 9% in 2001 (P < .05). The contribution margin of a PAWS visit and total contribution margin in 2007 were $1052 and $4.0 million, respectively. CONCLUSION: The creation of PAWS has allowed for the transition in management of most pediatric skin and soft tissue wounds and infections to an independent ambulatory setting, alleviating the need for operating room resources, while functioning at a profitable cost margin for the hospital.

[Cost-effectiveness analysis of vacuum-assisted closure in the surgical wound bed preparation of soft tissue injuries]. / Evaluation coût-efficacité de la thérapie par pression négative dans la préparation chirurgicale des pertes de substance cutanée.

This work proposes, from the point of view of the University Hospital Center of Nantes (acute care), a cost-effectiveness assessment of negative pressure wound therapy (NPWT), in comparison with moist wound therapy, in the surgical preparation of cutaneous defects requiring reconstructive surgery. This retrospective study was realized after data collection from patient files with hospitalization for the management of open-leg fractures with a view to reconstructive surgery by graft or flap (Cauchoix II or III). Effectiveness criteria, after debridement and NWPT initiation, was the time period required for preparing the wound for definitive reconstructive surgery closure by flap or graft. NWPT is compared, over the same 2000 to 2006 period, to the only existing therapeutic alternative, that is to say moist wound therapy. Only direct costs in relation with consumed resources dedicated to each medical strategy were taken into account. A Mann-Whitney U nonparametric test and boostrap technique have been used for statistical and sensitivity analysis. Twenty-five patients were recruited for the two medical strategies. Wound preparation time is significantly shorter for patient treated with NPWT (p=0.026 Mann-Whitney U-test) and is equal to 20 days less on average for time period required for preparing the wound for reconstructive surgery. Hospitalization costs is very significantly lower for patients being treated with NPWT (p=0.02). In absolute value, this cost is reduced on the average by 6000 euro per patient (i.e. by more than 60%). The incremental cost-effectiveness ratio is of the order of 164 euro per day of wound preparation for surgery gained.

Versatility of the anterolateral thigh flap with vascularized fascia lata for reconstruction of complex soft-tissue defects: clinical experience and functional assessment of the donor site.

BACKGROUND: The anterolateral thigh flap is commonly used for reconstruction of various soft-tissue defects. This article presents the authors' approach to one-stage reconstruction of composite soft-tissue defects using an anterolateral thigh flap with a vascularized fascia lata. METHODS: This retrospective review analyzed 973 patients who had undergone anterolateral thigh flap reconstruction for various soft-tissue defects over the past 10 years. Various types of complicated defects in 36 patients were reconstructed with a composite anterolateral thigh flap combined with vascularized fascia lata. The fascia lata component of the flap was used for abdominal wall and fascial defect reconstruction in 12 patients, for lip-cheek defect reconstruction in 15 patients, for reconstruction of composite defects in extremities in nine patients, and for reconstruction of the perineum in one patient. Functional outcomes of donor sites were investigated by using a dynamometer. RESULTS: All flaps except one survived. The overall flap survival rate was 97 percent. Patients achieved satisfactory results without major postoperative complications. The study revealed that vascularized fascia may mimic a fascial sheath but lacks the muscle-synchronized excursion properties. Apart from a mild deficiency in quadriceps femoris muscles contraction in the donor thighs, no difficulties in daily ambulation were reported by the patients. CONCLUSIONS: The anterolateral thigh flap with vascularized fascia lata provides a reliable fascial component for single-stage reconstruction of complex soft-tissue defects.

Soft tissue coverage at the resource-challenged facility.

Covering soft tissue defects remains challenging for orthopaedic surgeons, especially those in resource-challenged facilities. Covering tissue defects follow a plan from simple to complex: primary closure, local flap, area flap, pedicle flap, and free flap. I will limit my discussion to the role of latter two. At the district-level hospital in Vietnam, pedicle flaps are generally more useful, so I will discuss free flaps only briefly. The choices of pedicle flaps include: kite flap, posterior interosseous flap, radial flap (Chinese flap), neurocutaneous flap, anterolateral thigh fasciocutaneous flap, gastrocnemius flap, sural flap, posterior leg flaps; we typically use a free flap with the latissimus dorsi. Soft tissue coverage with pedicle flaps has many advantages: reliability, relatively easy harvest, and good blood supply. Free flaps with microanastomosis have an important place in covering difficult medium- or large-sized soft tissue defects but also require more instruments and more highly trained surgeons.
