RESUMEN
PURPOSE: Synovial fluid cultures of periprosthetic joint infections (PJI) may be limited by bacteria living in the fluids as biofilm-aggregates. The antibiofilm pre-treatment of synovial fluids with dithiotreitol (DTT) could improve bacterial counts and microbiological early stage diagnosis in patients with suspected PJI. METHODS: Synovial fluids collected from 57 subjects, affected by painful total hip or knee replacement, were divided into two aliquots, one pre-treated with DTT and one with normal saline. All samples were plated for microbial counts. Sensitivity of cultural examination and bacterial counts of pre-treated and control samples were then calculated and statistically compared. RESULTS: Dithiothreitol pre-treatment led to a higher number of positive samples, compared to controls (27 vs 19), leading to a statistically significant increase in the sensitivity of the microbiological count examination from 54.3 to 77.1% and in colony-forming units count from 1884 ± 2.129 CFU/mL with saline pre-treatment to 20.442 ± 19.270 with DTT pre-treatment (P = 0.02). CONCLUSIONS: To our knowledge, this is the first report showing the ability of a chemical antibiofilm pre-treatment to increase the sensitivity of microbiological examination in the synovial fluid of patients with peri-prosthetic joint infection. If confirmed by larger studies, this finding may have a significant impact on routine microbiological procedures applied to synovial fluids and brings further support to the key role of bacteria living in biofilm-formed aggregates in joint infections.

PURPOSE: Among the functional impairments associated with pelvic ring injuries (PRI), sexual dysfunction (SD) is a common clinical issue. The aim of this study is to investigate correlations between traumatic PRI, genitourinary, and sexual dysfunctions, for a proper multidisciplinary treatment. METHODS: We performed an observational, multicentric study, from January 2020 to 2022. We conducted a follow-up after surgery at three, six, 12, and 24 months by measuring the Female Sexual Functioning Index (FSFI), the International Index of Erectile Function (IIEF), the Arizona Sexual Experience Scale (ASEX), the Majeed Score, and the SF-12. Descriptive statistics was conducted on T-test, Whelc's test, and one-way ANOVA which were performed when appropriate. RESULTS: A total of 76 patients (mean age 42.17 ± 15 years) were included in the study and allocated into three groups (A, B, and C). Tile A group revealed good sexual outcomes, similar to that of healthy patients. Tile B group demonstrated worsen SD than the previous group. In Tile C group, there was a longer average duration of the orthopaedic surgery when compared to group B. However, in terms of SDs, statistical significance could not be demonstrated between groups C and B. CONCLUSIONS: We observed a progressive spontaneous recovery of sexual function, corresponding to each PRI group. Moreover, men classified as B2 had milder SDs than B1 male patients.

BACKGROUND: There is no evidence in the current literature about the best treatment option in sacral fracture with or without neurological impairment. MATERIALS AND METHODS: The Italian Pelvic Trauma Association (A.I.P.) decided to organize a consensus to define the best treatment for traumatic and insufficiency fractures according to neurological impairment. RESULTS: Consensus has been reached for the following statements: When complete neurological examination cannot be performed, pelvic X-rays, CT scan, hip and pelvis MRI, lumbosacral MRI, and lower extremities evoked potentials are useful. Lower extremities EMG should not be used in an acute setting; a patient with cauda equina syndrome associated with a sacral fracture represents an absolute indication for sacral reduction and the correct timing for reduction is "as early as possible". An isolated and incomplete radicular neurological deficit of the lower limbs does not represent an indication for laminectomy after reduction in the case of a displaced sacral fracture in a high-energy trauma, while a worsening and progressive radicular neurological deficit represents an indication. In the case of a displaced sacral fracture and neurological deficit with imaging showing no evidence of nerve root compression, a laminectomy after reduction is not indicated. In a patient who was not initially investigated from a neurological point of view, if a clinical investigation conducted after 72 h identifies a neurological deficit in the presence of a displaced sacral fracture with nerve compression on MRI, a laminectomy after reduction may be indicated. In the case of an indication to perform a sacral decompression, a first attempt with closed reduction through external manoeuvres is not mandatory. Transcondylar traction does not represent a valid method for performing a closed decompression. Following a sacral decompression, a sacral fixation (e.g. sacroiliac screw, triangular osteosynthesis, lumbopelvic fixation) should be performed. An isolated and complete radicular neurological deficit of the lower limbs represents an indication for laminectomy after reduction in the case of a displaced sacral fracture in a low-energy trauma associated with imaging suggestive of root compression. An isolated and incomplete radicular neurological deficit of the lower limbs does not represent an absolute indication. A worsening and progressive radicular neurological deficit of the lower limbs represents an indication for laminectomy after reduction in the case of a displaced sacral fracture in a low-energy trauma associated with imaging suggestive of root compression. In the case of a displaced sacral fracture and neurological deficit in a low-energy trauma, sacral decompression followed by surgical fixation is indicated. CONCLUSIONS: This consensus collects expert opinion about this topic and may guide the surgeon in choosing the best treatment for these patients. LEVEL OF EVIDENCE: IV. TRIAL REGISTRATION: not applicable (consensus paper).

PURPOSE: The optimal operative treatment for displaced acetabular fractures in elderly population is still object of debate. Acute fix and replace procedure, the so called "combined hip procedure" (CHP), was introduced because of the poor results of the open reduction and internal fixation (ORIF) alone. The aim of the study is to compare clinical outcomes of CHP and ORIF alone for the treatment of acetabular fractures in elderly patients. METHODS: This is the largest multicentric retrospective analytical study, with a case-control design on the issue. Hospital records and clinical notes were reviewed to collect demographic, peri-operative, and clinical data. RESULTS: A total of 45 patients met the inclusion criteria: 24 patients entered the CHP group whereas 21 entered the ORIF control group. The mean age was 69.5 + - 1.12 years in the ORIF group and 73.4 + - 1.84 in the control group. The most frequent traumatic mechanism was the fall from same level in both groups (37.5% CHP; 42.9% ORIF). Operating time was significantly lower in the CHP group compared to the ORIF group (207 + - 11.0 ORIF; 175 + - 9.16 CHP; p < 0.05). Moreover, full weight-bearing was allowed significantly earlier in the CHP group compared to ORIF alone (37.3 + - 1.59 ORIF; 32.5 + - 1.69 CHP; p < 0.05). Among the clinician-completed scores, the HHS at three months was higher in the CHP group (66.3 + - 1.83 ORIF;73.6 + - 2.09 CHP; p < 0.05). All the other clinical outcomes were similar in both study groups. CONCLUSION: CHP is desirable treatment option in elderly patients with acetabular fracture when there are poor expected outcomes in terms of joint survival with ORIF alone.

BACKGROUND AND AIM: Sacral fractures with concomitant unstable pelvic ring injuries are severe conditions which occur in patients involved in high-energy trauma. When operative treatment is required, high surgical experience on the field is mandatory, especially in a sub-polpulation of obese patients which have increased risk of complications. The aim of this multicentric retroscpective study was to describe and analyze clinical and radiological outcomes of sacral vertical fractures in obese patients with a minimum of 2 years follow-up. Methods: A total of 121 pelvic fractures admitted to Emergency Departments of three II level trauma centres from April 2015 to April 2021 were retrospectively reviewed. Demographics, injury mechanism, surgical data and complications were collected. The quality of life and the pelvic function were respectively measured by SF-12 questionnaires, Denis Work Scale and Majeed Score. The inter-rater agreement between the clinical scores and the Denis Work Scale was assessed. Results: A total of 19 patients were included in the study. The average follow up was 41.16 months. The average BMI was 38.63 and the mean abdominal circumference was 128.10 cm. The average Majeed and SF-12 scores were respectively 66.47 and 74.32. Five patients were able to return to their previous employment. The post traumatic life's quality and related dysfunctions are influenced by the high BMI. Conclusions: Faster recovery and early weight-bearing should be persued in order to minimize complications, expecially in obese patients. In these sample of patients, "triangular osteosynthesis" was the best treatment choice for sacral vertical fractures.

Aim To investigate the effects of surgical reduction of complex acetabular fractures on spine balance, postural stability and quality of life. Methods Twenty-six patients with acetabular fractures surgically treated by open reduction and internal fixation were divided into two groups according to the amount of reduction. Group A consisted of 18 patients with satisfactory reduction (≤2 mm), and group B of eight patients with incomplete reduction (>2 mm). Functional outcome was measured with Harris Hip Score (HHS), Oswestry Disability Index (ODI), and Short Form (12) Health Survey (SF12). Radiological parameters were assessed with standing whole spine, pelvis and hip X-rays, including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), and sagittal vertical axis (SVA). Follow-up intervals were 1, 3, 6 and 12 months and annually thereafter. Gait analysis and baropodometry were performed after 24 months of operation. Results Mean HHS, ODI, and SF-12 was improved during the first postoperative year in both groups. After two years average scores kept improving for group A, but worsened for group B. Mean PI, PT, and SS increased in both groups during the first postoperative year, with further increase after two years only in group B. After two years, 16 (89%) patients in group A and four (50%) in group B had a balanced spine (SVA <50 mm). Gait analysis and baropodometry showed greater imbalance and overload for group B compared to group A. Conclusion In the long term, incomplete reduction of associated acetabular fractures may lead to poor outcome because of secondary spinopelvic imbalance, with posture and gait impairment.

Aim To propose a new prognostic classification system for pelvic injuries based on a new detailed and all-encompassing evaluation of the injury pelvic outcome score and to check the prognostic value of this classification and evaluate its reliability and reproducibility. Methods From January 2017 to June 2020 from 156 pelvic fractures treated at our hospitals, 98 patients with pelvic fractures were recruited according to inclusion and exclusion criteria. All patients compiled three scores (New Score System, Majeed Score, SF-12) sessions two times during the hospital stay to evaluate the endpoint before the trauma and two years after the trauma. All patients carried out three tests independently. The evaluation of three scores included a pelvic and general complication after the surgery, the times needed to compile three score system. For reliability of the new score systems we evaluated the inter-observer or intraobserver agreement, the prediction strength of each score, and a prognostic value. Results A total of 98 patients were enrolled (74 were males and 24 females) with mean age of 43.6 (±18.6) (range 16-75) years. Tau B Kendall value was 0.827 for the new score system, 0.673 for the Majeed score, 0.746 for SF-12, there was p<0.05 for the new score system. Conclusion The new score system is prognostic, reliable, reproducible and can become a useful instrument to adequately correlate the long-term outcomes of pelvic injury fractures. Also, it provides a better evaluation of pain, work, sexual possibilities and satisfaction, balance-sitting-walking and psychological status.

Aim Multifragmentary segmental femoral shaft fracture is a high energy injury frequently associated with life-threatening conditions. The aim of this study was to compare the use of bio metallic open reduction internal fixation (ORIF) (plate with allograft bone strut) with minimally invasive plate osteosynthesis (MIPO) fixation for the treatment of multi-segmental femoral shaft fracture in terms of outcomes, bone healing and complications. Methods Forty patients with segmental femoral shaft fractures were included and divided into two groups: 20 patients treated with ORIF+, 20 with MIPO. All fractures were classified according to AO (Arbeitsgemeinschaft für Osteosynthesefragen) and Winquist and Hansen Classification. Evaluation criteria were: duration of follow up and surgery, Non-Union Scoring System, Pain Visual Analogic Scale (VAS), objective quality of life and hip function, subjective quality of life and knee function, quality of life the Short Form-12 Survey Questionnaires (SF-12), bone healing and femoral alignment (radiographs), Radiographic Union Score for Hip (RUSH). Results Better results of ORIF in terms of complication rate, RUSH, VAS, regression between RUSH and VAS, average correlation clinical-radiographic results and patients' outcomes (Cohen k) were obtained, and similar results for the length of follow up, surgery duration, perioperative blood transfusion, wound healing. No statistical difference for Harris Hip Score (HHS), Knee Society Score (KSS), quality of life (SF-12). Conclusions The ORIF and bone strut allograft technique had better results compared to the MIPO technique with regards to complication rate, RUSH, VAS, regression between RUSH and VAS, and average correlation clinical-radiographic results and patients' outcomes (Cohen k) in the surgical treatment of multifragmentary segmental femoral shaft fractures.

INTRODUCTION: Floating knee is a flail knee joint resulting from fractures of the shafts or adjacent metaphyses of the femur and the ipsilateral tibia. It is usually associated with several complications and mortality. This study was designed to present our experience with the treatment of this injury. MATERIAL AND METHOD: This study was performed between January 2004 and December 2014. 224 cases of floating knee injuries gathered from the 34,480 lower extremities trauma files were studied, and the target information recorded. The injuries most frequently occurred in subjects between 16 and 35 years of age (60.71%), and in male subjects (85.71%). The most frequent mechanism of injury was traffic accident (92.85%). External fixation was the common type of treatment (82.14%) in emergency or as a definitive treatment. The treatment was performed within 24 h of the trauma. We performed a 36-month follow up with clinical examination, radiographs, assessing the complications, and using the Modified Cincinnati Rating System Questionnaire (MCRSQ) and the Karlström/Olerud Score (KOS) to evaluate the progression of the outcomes. RESULTS: Early complications included 8 cases of compartment syndrome, 60 open fractures and 24 partially amputated limbs. A total amputation was performed in 3 patients. The most common late complication was heterotopic calcifications of the knee (n = 68, 30.6%). Good scores for MCRSQ and KOS were obtained only after patients were sent to a reference center for knee surgery. CONCLUSIONS: Our experience revealed that the complication rate associated with floatingknee injuries remains high, regardless of the performed treatment. Surgeons should focus on reducing complications while treating these severe injuries.

RESUMEN
BACKGROUND: In critically ill patients with colonization/infection of multidrug-resistant organisms, source control surgery is one of the major determinants of clinical success. In more complex cases, the use of different tools for sepsis management may allow survival until complete source control. CASE PRESENTATION: A 42-year-old white man presented with traumatic hemorrhagic shock. Unstable pelvic fractures led to emergency stabilization surgery. Fever ensued with diarrhea, followed by septic shock. Two weeks later, an abdominal computed tomography scan revealed suprapubic and ischiatic abscesses at surgical sites, as well as dilated bowel. Debridement of both surgical sites, performed with vacuum-assisted closure therapy, yielded isolates of carbapenem and colistin-resistant Klebsiella pneumoniae. Antibiotic treatment was de-escalated after 21 days; 4 days later fever, leukocytosis, hypotension and acute renal failure relapsed. Blood purification techniques were started, for the removal of endotoxin and inflammatory mediators, with sequential hemodialysis. Clinical improvement ensued; blood cultures yielded Candida albicans and multidrug-resistant Acinetobacter baumannii; panresistant carbapenemase-producing Klebsiella pneumoniae grew from wound swabs. In spite of shock reversal, our patient remained febrile, with diarrhea. Control blood cultures yielded Candida albicans, Acinetobacter baumannii and carbapenem-resistant Klebsiella pneumoniae. His abdominal pain increased, paralleled by a right flank palpable mass. Colonoscopy revealed patchy serpiginous ulcers. At exploratory laparotomy, an inflammatory post-traumatic pseudotumor of his right colon was removed. Blood cultures turned negative after surgery. Septic shock, however, relapsed 4 days later. A blood purification cycle was repeated and combination antimicrobial therapy continued. Surgical wounds and blood cultures were persistently positive for carbapenem-resistant Klebsiella pneumoniae. Removal of pelvic synthesis media was therefore anticipated. Three weeks later, clinical, microbiological, and biochemical evidence of infection resolved. CONCLUSIONS: High quality intensive assistance for sepsis episodes needs a clear plan of cure, aimed to complete infection source control, in a complex multidisciplinary interplay of specialists and intensive care physicians.

OBJECTIVE: To present the experience in a single institution of the management of 82 consecutive fractures and fracture-dislocations of the proximal humerus treated with the Proximal Humeral Internal Locking System (Philos(®)) plate. MATERIALS AND METHODS: A total of 81 patients with 82 proximal humerus fractures (one patient had bilateral fracture) were treated at our institution with open reduction and internal fixation with Philos(®) plate from January 2008 to December 2012 and the clinico-radiological outcome was analysed. Twelve of these patients also had a dislocation of the proximal humerus. According to the Neer classification, there were seven two-part fractures, 40 three-part fractures and 35 four-part fractures. All patients received a similar physical therapy programme following internal fixation. Mean final follow-up was 32 months. Functional outcome was evaluated for each patient using the Constant-Murley score; radiographic evaluation was also conducted and complications were recorded. RESULTS: At the end of the follow-up period, the mean Constant-Murley score for the injured side was 75 points (range 42-92); results were graded as excellent for eight patients, good for 52, moderate for 17 and poor for five. Twenty-three patients (28%) had complications during the follow-up period. Reoperation was required in 12 patients. Complications included avascular necrosis of the humeral head in 10 patients (12%), varus positioning of the head in four patients (4.8%), impingement syndrome in three patients (3.6%), secondary screw perforation in three patients (3.6%), non-union of the fracture in two patients (2.4%) and infection in one patient (1.2%). CONCLUSIONS: Open reduction and internal fixation of proximal humeral fractures with the Philos(®) plate was associated with good clinical outcomes provided the correct surgical technique was used. To better evaluate the real incidence of complications, it is important to follow patients for more than one year after surgery as some complications may arise after this time.
