RESUMEN

Background: The optimal duration and choice of antibiotic for fracture-related infection (FRI) is not well defined. This study aimed to determine whether antibiotic duration (≤6 vs >6 weeks) is associated with infection- and surgery-free survival. The secondary aim was to ascertain risk factors associated with surgery- and infection-free survival. Methods: We performed a multicenter retrospective study of patients diagnosed with FRI between 2013 and 2022. The association between antibiotic duration and surgery- and infection-free survival was assessed by Cox proportional hazard models. Models were weighted by the inverse of the propensity score, calculated with a priori variables of hardware removal; infection due to Staphylococcus aureus, Staphylococcus lugdunensis, Pseudomonas or Candida species; and flap coverage. Multivariable Cox proportional hazard models were run with additional covariates including initial pathogen, need for flap, and hardware removal. Results: Of 96 patients, 54 (56.3%) received ≤6 weeks of antibiotics and 42 (43.7%) received >6 weeks. There was no association between longer antibiotic duration and surgery-free survival (hazard ratio [HR], 0.95; 95% CI, .65-1.38; P = .78) or infection-free survival (HR, 0.77; 95% CI, .30-1.96; P = .58). Negative culture was associated with increased hazard of reoperation or death (HR, 3.52; 95% CI, 1.99-6.20; P < .001) and reinfection or death (HR, 3.71; 95% CI, 1.24-11.09; P < .001). Need for flap coverage had an increased hazard of reoperation or death (HR, 3.24; 95% CI, 1.61-6.54; P = .001). Conclusions: The ideal duration of antibiotics to treat FRI is unclear. In this multicenter study, there was no association between antibiotic treatment duration and surgery- or infection-free survival.

RESUMEN

Here, we describe the case of an 80-year-old female patient with type II insulin-dependent diabetes mellitus with a left proximal tibia fracture. Open reduction internal fixation was performed using a locking plate. After the surgical site infection, the plate was removed and negative-pressure wound therapy was applied. The bone was covered with a vastus medialis muscle flap, and a split-thickness skin graft and external fixation using an Ilizarov device was performed as the definitive treatment.

RESUMEN

Infection after fracture fixation (IAFF) in orthopaedic surgery is a significant complication that can lead to disability due to chronic infection and/or relapsing disease, non-union necessitating revision surgery. Management of IAFF is a major challenge facing orthopaedic surgeons across the world due to two key pathogenic mechanisms of Biofilm formation and antimicrobial resistance (AMR) against traditional antibiotics. Advanced prophylactic and treatment strategies to help eradicate established infections and prevent the development of such infections are necessary. Bacteriophage therapy represents an innovative modality to treat IAFF due to multi-drug resistant organisms. We assess the current role and potential therapeutic applications of the novel bacteriophage therapy in the management of these recalcitrant infections to achieve a successful outcome.

RESUMEN

INTRODUCTION AND IMPORTANCE: Infection after fracture fixation (IAFF) is one of the most challenging issues for the lower-middle class socioeconomic. It is also related to unsatisfactory outcome of the treatment. Arthroscopy usually used to treat joint disease, but the evidence of arthroscopic management in IAFF is still limited. CASE PRESENTATION: We present a case of 54-year-old female with IAFF of the ankle. An arthroscopic debridement and soft tissue release procedure were performed in this patient in one stage because the irrigation and debridement were sufficient. It showed a good result good functional outcome. CLINICAL DISCUSSION: The aims of IAFF treatment are to eradicate the infection, promote healing of soft tissue, prevent osteomyelitis, restore the joint function, and fracture consolidation. Arthroscopy in IAFF has been found to be safe and effective. In this case, arthroscopy was done in one stage because the debridement and irrigation were sufficient while the delay of the release would result in further pain and morbidity for the patient. CONCLUSION: Arthroscopic debridement with simultaneous release of impingement and stiffness is a novel, safe, and promising option in to eliminate both IAFF and its further complications of the ankle region.

RESUMEN

BACKGROUND: Surgical site infections (SSI) after distal radius fracture (DRF) surgery have not previously been studied as the primary outcome in a large population with comparative data for different surgical methods. The aims of this study were 1) to compare SSI rates between plate fixation, percutaneous pinning and external fixation, and 2) to study factors associated with SSI. METHODS: We performed a nation-wide cohort study linking data from the Swedish national patient register (NPR) with the Swedish prescribed drug register (SPDR). We included all patients ≥18 years with a registration of a surgically treated DRF in the NPR between 2006 and 2013. The primary outcome was a registration in the SPDR of a dispensed prescription of peroral Flucloxacillin and/or Clindamycin within the first 8 weeks following surgery, which was used as a proxy for an SSI. The SSI rates for the three main surgical methods were calculated. Logistic regression was used to study the association between surgical method and the primary outcome, adjusted for potential confounders including age, sex, fracture type (closed/open), and a dispensed prescription of Flucloxacillin and/or Clindamycin 0-8 weeks prior to DRF surgery. A classification tree analysis was performed to study which factors were associated with SSI. RESULTS: A total of 31,807 patients with a surgically treated DRF were included. The proportion of patients with an SSI was 5% (n = 1110/21,348) among patients treated with plate fixation, 12% (n = 754/6198) among patients treated with percutaneous pinning, and 28% (n = 1180/4261) among patients treated with external fixation. After adjustment for potential confounders, the surgical method most strongly associated with SSI was external fixation (aOR 6.9 (95% CI 6.2-7.5, p < 0.001)), followed by percutaneous pinning (aOR 2.7 (95% CI 2.4-3.0, p < 0.001)) (reference: plate fixation). The classification tree analysis showed that surgical method, fracture type (closed/open), age and sex were factors associated with SSI. CONCLUSIONS: The SSI rate was highest after external fixation and lowest after plate fixation. The results may be useful for estimation of SSI burdens after DRF surgery on a population basis. For the physician, they may be useful for  estimating the likelihood of SSI in individual patients.

RESUMEN

A precise definition of infection after fracture fixation is essential for the evaluation of published research data and for the future establishment of uniform treatment concepts. Recently, a multidisciplinary expert panel has developed a consensus definition that includes 4 confirmatory criteria for infection following fracture fixation. These criteria are: Fistula, sinus, or wound breakdown; purulent drainage or deep purulence at surgery; positive cultures from at least 2 separate deep tissue/implant specimens taken during an operative intervention; and microorganisms in deep tissue specimens confirmed by histopathological staining. The consensus panel also identified 6 categories of suggestive criteria which are features associated with infection that requires further investigation.

RESUMEN

One of the most challenging complications in trauma surgery is infection after fracture fixation (IAFF). IAFF may result in permanent functional loss or even amputation of the affected limb in patients who may otherwise be expected to achieve complete, uneventful healing. Over the past decades, the problem of implant related bone infections has garnered increasing attention both in the clinical as well as preclinical arenas; however this has primarily been focused upon prosthetic joint infection (PJI), rather than on IAFF. Although IAFF shares many similarities with PJI, there are numerous critical differences in many facets including prevention, diagnosis and treatment. Admittedly, extrapolating data from PJI research to IAFF has been of value to the trauma surgeon, but we should also be aware of the unique challenges posed by IAFF that may not be accounted for in the PJI literature. This review summarizes the clinical approaches towards the diagnosis and treatment of IAFF with an emphasis on the unique aspects of fracture care that distinguish IAFF from PJI. Finally, recent developments in anti-infective technologies that may be particularly suitable or applicable for trauma patients in the future will be briefly discussed.

RESUMEN

INTRODUCTION: One of the most challenging musculoskeletal complications in modern trauma surgery is infection after fracture fixation (IAFF). Although infections are clinically obvious in many cases, a clear definition of the term IAFF is crucial, not only for the evaluation of published research data but also for the establishment of uniform treatment concepts. The aim of this systematic review was to identify the definitions used in the scientific literature to describe infectious complications after internal fixation of fractures. The hypothesis of this study was that the majority of fracture-related literature do not define IAFF. MATERIAL AND METHODS: A comprehensive search was performed in Embase, Cochrane, Google Scholar, Medline (OvidSP), PubMed publisher and Web-of-Science for randomized controlled trials (RCTs) on fracture fixation. Data were collected on the definition of infectious complications after fracture fixation used in each study. Study selection was accomplished through two phases. During the first phase, titles and abstracts were reviewed for relevance, and the full texts of relevant articles were obtained. During the second phase, full-text articles were reviewed. All definitions were literally extracted and collected in a database. Then, a classification was designed to rate the quality of the description of IAFF. RESULTS: A total of 100 RCT's were identified in the search. Of 100 studies, only two (2%) cited a validated definition to describe IAFF. In 28 (28%) RCTs, the authors used a self-designed definition. In the other 70 RCTs, (70%) there was no description of a definition in the Methods section, although all of the articles described infections as an outcome parameter in the Results section. CONCLUSION: This systematic review shows that IAFF is not defined in a large majority of the fracture-related literature. To our knowledge, this is the first study conducted with the objective to explore this important issue. The lack of a consensus definition remains a problem in current orthopedic trauma research and treatment and this void should be addressed in the near future.

RESUMEN

INTRODUCTION: One of the most challenging complications in musculoskeletal trauma surgery is the development of infection after fracture fixation (IAFF). It can delay healing, lead to permanent functional loss, or even amputation of the affected limb. The main goal of this study was to investigate the total healthcare costs and length-of-stay (LOS) related to the surgical treatment of tibia fractures and furthermore identify the subset of clinical variables driving these costs within the Belgian healthcare system. The hypothesis was that deep infection would be the most important driver for total healthcare costs. PATIENTS AND METHODS: Overall, 358 patients treated operatively for AO/OTA type 41, 42, and 43 tibia fractures between January 1, 2009 and January 1, 2014 were included in this study. A total of 26 clinical and process variables were defined. Calculated costs were limited to hospital care covered by the Belgian healthcare financing system. The five main cost categories studied were: honoraria, materials, hospitalization, day care admission, and pharmaceuticals. RESULTS: Multivariate analysis showed that deep infection was the most significant characteristic driving total healthcare costs and LOS related to the surgical treatment of tibia fractures. Furthermore, this complication resulted in the highest overall increase in total healthcare costs and LOS. Treatment costs were approximately 6.5-times higher compared to uninfected patients. CONCLUSION: This study shows the enormous hospital-related healthcare costs associated with IAFF of the tibia. Treatment costs for patients with deep infection are higher than previously mentioned in the literature. Therefore, future research should focus more on prevention rather than treatment strategies, not only to reduce patient morbidity but also to reduce the socio-economic impact.
