To describe clinical situations for use of modified VAC in POC based on: diagnosis, comorbidities, BMI, wound size in cm, days following trauma when VAC was first applied, total duration of uninterrupted use, frequency of change, settings, bacterial growth, outcomes. To report the outcomes of mVAC use in POC within 6 months to help improve and standardize its application in the institution. This study involves data gathering from inpatients handled by orthopedic surgeons in training and subspecialty rotations in POC. The data collected are highly dependent on the doctors-in-charge's complete charting, thorough reporting and accurate documentation. Modified Vacuum Assisted Closure (mVAC) is used frequently in this study and is defined as a form of revised, adapted and reformed use of VAC based on available materials in the involved institution. The materials that are included are, but not limited to the following: sterile Uratex™ blue foam, nasogastric or suction tubing, phlegm suction machine, Bactigras™ and Opsite™ or Ioban™. A total of 58 patients were included in the study. The average age of the population was 35 and are predominantly male. The most common mechanism of injury was motorcycle accident and 37 of the patients were diagnosed with an open fracture of the lower extremity with open tibia fractures (22) being the most common. Average wound area measured was 24.12 cm. 3. All patients yield a bacteria growth with e. coli being the most frequent. Average during of uninterrupted use was 39 days. Of the 58 included in the study, 8 patients underwent STSG, 2 had a flap coverage surgery, 4 patients eventually underwent amputation and 33 with complete resolution of soft tissue defect after conversion to biologic dressing post-mVAC. The rest of the population were still ongoing mVAC at the end of the study. mVAC is an alternative temporary medium for soft tissue coverage for cases with or without concomitant fractures. mVAC promotes removal of exudate from the wound, supports wound apposition and granulation bed proliferation. Usage mVAC helps prepare for skin coverage procedure and on some cases leads to full resolution of defect

Aim. Pelvic osteomyelitis following pressure ulceration results in substantial patient morbidity. Previous studies have reported a heterogenous approach to diagnosis and medical management by physicians, suggesting equipoise on key clinical questions. This study hypothesised that the same equipoise exists amongst Orthopaedic surgeons. Method. An 18-question multiple-choice questionnaire was designed through an iterative feedback process until the final version was agreed by all authors. Likert-type scale responses were used with graded responses (e.g., never/fewer than half of patients/around half of patients/more than half of patients/every patient). The online survey was sent to members of the Musculoskeletal Infection Society (MSIS), the European Bone and Joint Infection Society (EBJIS), and the ESCMID Study Group for Implant-Associated Infections (ESGIAI). No incentive for participation was provided. Results. Amongst respondents, 22/41 were based in Europe and 10/41 from the USA. The majority (29/41) had been in clinical practice between 5—24 years. There was a high priority placed on bone biopsy histology, culture-positive bone sampling, and palpable bone without periosteal covering for diagnosis. Multidisciplinary team approach with plastic surgery involvement at the index procedure was advocated. The strongest indications for surgical intervention were source control for sepsis, presence of an abscess/collection, and prevention of local osteomyelitis progression. Physiological/psychological optimisation and control of acute infection were the primary determinants of surgical timing. There was low utilisation of adjunctive surgical therapies. Local/regional primary tissue transfer or secondary healing with/without VAC were the preferred techniques for wound closure. Recurrent osteomyelitis was the most common reason for prolonged antimicrobial therapy. The majority received bedside advice from an infectious disease-specialist but a quarter of respondents preferred telephone advice. Conclusions. Amongst an international cohort of Orthopaedic Surgeons there was a heterogenous diagnostic and therapeutic approach to pressure-related pelvic osteomyelitis

Aims

The Open-Fracture Patient Evaluation Nationwide (OPEN) study was performed to provide clarity in open fracture management previously skewed by small, specialist centre studies and large, unfocused registry investigations. We report the current management metrics of open fractures across the UK.

Aim. The purpose of this study is to analyze the demographic and microbiological variables of acute ankle infections posterior to ankle osteosynthesis and to determine the different characteristics of patients withE. cloacae infection. Method. A multicenter retrospective observational study (4 national hospitals) of acute post osteosynthesis infections of ankle fracture operated between 2015 and 2018 was implemented. The demographic and microbiological variables relating to the surgical intervention and the antibiotic treatment performed were collected. A descriptive assessment of all the variables and a univariate comparison between patients with E. cloacae infection and patients with alternative microorganism infections were performed. The SPSS v25 program for Windows was the choice for statistical analysis. Results. 71 Patients with an average age of 57 years were included, the majority being males (55%). 31% of patients were diabetic, 27% had vascular pathology, and 18.3% had a BMI greater than 35. Trimalleolar fracture was the most common in our study being 52%. 26.8% were open fractures. The microorganisms isolated were: 25% S. aureus, 22.5% E. cloacae and 22.5% polymicrobial. Accounting for polymicrobial infections, the presence of E. cloacae rises to 32%. In the univariate analysis, only significant differences were found in age (patients with E. cloacae infection were older) and the use of VAC therapy. Conclusions. In our series, higher percentages of E. cloacae infection were observed than those described in the literature. There are statistically significant differences in the variables of age and need for VAC therapy. The high incidence of E. cloacae infections suggests the vital importance of adapting antibiotic prophylaxis, ensuring the coverage of this microorganism

Aims

The aims of the study were to analyze differences in surgical and oncological outcomes, as well as quality of life (QoL) and function in patients with ankle sarcomas undergoing three forms of surgical treatment, minor or major limb salvage surgery (LSS), or amputation.

Aims

Limb salvage in bone tumour patients replaces the bone with massive segmental prostheses where achieving bone integration at the shoulder of the implant through extracortical bone growth has been shown to prevent loosening. This study investigates the effect of multidrug chemotherapy on extracortical bone growth and early radiological signs of aseptic loosening in patients with massive distal femoral prostheses.

Aims

It has been generally accepted that open fractures require early skeletal stabilization and soft-tissue reconstruction. Traditionally, a standard gauze dressing was applied to open wounds. There has been a recent shift in this paradigm towards negative pressure wound therapy (NPWT). The aim of this study was to compare the clinical outcomes in patients with open tibial fractures receiving standard dressing versus NPWT.

Aims

Diagnosis of cauda equina syndrome (CES) remains difficult; clinical assessment has low accuracy in reliably predicting MRI compression of the cauda equina (CE). This prospective study tests the usefulness of ultrasound bladder scans as an adjunct for diagnosing CES.

Aims

The aim of this study was to estimate the cost-effectiveness of negative-pressure wound therapy (NPWT) in comparison with standard wound management after initial surgical wound debridement in adults with severe open fractures of the lower limb.

Aims

This study reviews the use of a titanium mesh cage (TMC) as an adjunct to intramedullary nail or plate reconstruction of an extra-articular segmental long bone defect.

Aim. Negative pressure wound treatment (NPWT) has been widely adopted in the management of septic wound complications or prophylactically after large surgeries. Recent publications have indicated the necessity of further investigations to support the use of NPWT with more evidences. Therefore, the purpose of this pilot-study was to investigate the efficacy of VAC-assisted dressing systems in the treatment of septic trauma cases. Method. We analysed data of 16 retrospective cases following traumas and septic soft tissue surgeries around the hip and knee. The collected data consisted of bacterial cultures, inflammatory markers (WBC, CRP/HCRP) and body temperature, taken periodically during treatment. Also recorded were the time periods the vacuum pump was used during treatment. To increase the number of measurements and to facilitate subsequent data analysis, the measurements were interpolated to regularly sampled curves with a sampling rate of one day. We used cross-plots and linear regression analysis to investigate trends in the data: 1) while the vacuum pump was switched on and 2) while it was switched off. Results. The analysis shows that the average WBC and CRP/HCRP values decline in the first days after initiation of the VAC treatment. WBC values decline in the first four days of VAC treatment (linear regression, R. 2. =0.960). CRP/HCRP values decline in the first thirteen days (linear regression, R. 2. =0.952). No meaningful trends were observed in body temperature measurements. Importantly, there is a trend for an increase of WBC and CRP/HCRP, following the 4. th. and 14. th. days, respectively. These findings suggest that the prolonged use of VAC treatment may result in secondary relapses. Conclusions. Our results indicate a marked decrease of inflammatory markers during the first two weeks, confirming the efficacy of NPWT in the management of septic wounds after traumas. Importantly, our analyses also show a periodic relapse with the prolonged use of NPWT. However, further studies are needed with a larger, standardized population to confirm these findings

Aims

The purpose of this prospective study was to evaluate the outcomes of coccygectomy for patients with chronic coccydynia.

To evaluate the value of the use of massive prostheses in periprosthetic infections both in one stage and two stages procedures. Between 2008 and 2014, 236 revisions for PJI had been performed in our hospital by the same surgeon. For the most complex cases, we decided to introduce megaprostheses in our practice in 2011. We report a prospective series of 33 infected patients treated between 2011 and the end of 2014, 14 male and 19 female with on average 67.9 years old (38–85) Infection involved TKA in 22 cases (17 TKA revisions, 4 primary TKA), THA in 9 cases (6 revisions, 3 primary THA), a femoral pseudo-arthrosis with posttraumatic gonarthrosis in one case and a septic humeral pseudoarthrosis in one case. We used a total femoral component for two patients: the first one for a hip PJI with extended diaphyseal bone loss and multiples sinus tracks, and the second one for a massive infected knee prosthesis used in a knee reconstruction for liposarcoma. We used one stage procedures in 20 cases (8 hips, 12 knees, 1 shoulder) and two stages in 13 cases (12 knees and 1 hip). Additional technics included 3 massive extensor system allografts, two local flaps. Perioperative hyperbaric treatment was used for 2 patients. The average follow up is 19.8 months (6–48 months). The most frequent complications were wound swelling and delayed healing in 8 cases;). In 3 cases of one stage surgery a complementary debridement was necessary in the three weeks after the surgery with always a good local and infectious evolution. VAC therapy was used in four cases with good results. We report one early postoperative dead. In summary, the use of massive prostheses in PJI is a good option for complex cases. It can be a good alternative to knee arthrodesis. These components must be used preferentially for older patients, in cases of extreme bone loss or extensive osteomyelitis to secure the bone debridement and the quality of the reconstruction. In our series, the one stage procedure is a validated option even by using complementary technics as bone allografts, extensor system allografts or flaps. We believe the two stages surgery is a secondary option, particularly when soft tissues status is compromised before or after the debridement, and mostly for the knees. The longevity of the implantation must be evaluate by a long term follow up

Chronic posttraumatic osteomyelitis (CPTO) is a complex condition that results in considerable morbidity and may be limb threatening. Tibia is the most common site of CPTO, with an average infection rate of 10% for open fractures and 1% for closed fractures. In most cases osteomyelitis is polymicrobial. Staphylococcus aureus is the most common infecting organism present either alone or in combination with other pathogens in 65 to 70% of patients. Adequate soft-tissue coverage is one of the cornerstones in chronic osteomyelitis management. Vacuum-assisted closure (VAC) is frequently used for the treatment of posttraumatic osteomyelitis of the extremities. After debridement and repeated VAC dressing changes, the wounds are closed by secondary suture, split-thickness skin grafts or local flaps. Free muscle flaps are recommended in distal third tibial defects. We present our experience with two case reports. The authors present two cases of type IIIA osteomyelitis according to Cierny-Mader classification, following previous distal third tibial open fractures. Both patients presented with limb deformity, insidious local pain and chronic purulent discharge (without significant local inflammatory signs) after 11 and 24 years of trauma. They were treated with radical debridement of all nonviable and infected tissue, VAC instillation therapy for 3 weeks and transverse rectus abdominis muscle (TRAM) flap defect coverage. Intra-operative cultures were positive for multiple pathogens. Specific antibiotic therapy was performed for each case for 8 weeks. Symptomatic relieve was achieved and C-reactive protein and white blood cell count returned to normal values. No complications were documented. 1 year post-surgery, both patients remain asymptomatic, with no signs of infection, with full flap integrity and gait without assistance. Despite the challenging management of chronic posttraumatic osteomyelitis of the tibia, infection control and a satisfactory functional outcome can be achieved. The cornerstones of management include infection control with surgical debridement, microbial-specific antibiotic administration and soft tissue coverage. VAC instillation therapy has an important role promoting granulation tissue formation and infection eradication. The aggressive approach, even with delay on diagnosis, is the key factor for a worthy outcome. Despite the good results, recrudescence of osteomyelitis is known to occur even years after the original offense is treated
