Perceptions of critically ill individuals with acute and chronic spinal cord injury requiring a tracheostomy tube.

STUDY DESIGN: Observational study. OBJECTIVES: To evaluate the perceptions of patients requiring a tracheostomy tube and to identify possible different perceptions in critically ill patients with tracheostomy tubes who have acute (ASCI) or chronic spinal cord injuries (CSCI). SETTING: Medical and surgical intensive care units (ICU) and intermediate care unit of the BG University Hospital Bergmannsheil Bochum, Germany. METHODS: Patients who met the inclusion criteria completed a 25-item questionnaire on two consecutive days regarding their experiences and perceptions in breathing, coughing, pain, speaking, swallowing, and comfort of the tracheostomy tube. RESULTS: A total of 51 persons with ASCI (n = 31) and CSCI (n = 20) were included with a mean age of 53 years. Individuals with ASCI reported significantly more frequent pain and swallowing problems as compared to individuals with CSCI (p ≤ 0.014) at initial assessment. There were no differences between ASCI and CSCI reported with respect to speaking and overall comfort. CONCLUSIONS: It is necessary to regularly assess the perceptions of critically ill patients with tracheostomy tubes with ASCI or CSCI in the daily ICU care routine. We were able to assess these perceptions in different categories. For the future, evaluating the perception of individuals with SCI and a tracheostomy should be implemented to their daily routine care. TRIAL REGISTRATION: DRKS00022073.

Behavioral pain scale may not be reliable in awake non-verbal intensive care patients: a case control study.

BACKGROUND: The evaluation of pain in patients, unable of oral communication, often relies on behavioral assessment. However, some critically ill patients, while non-verbal, are awake and have some potential for self-reporting. The objective was to compare the results of a behavioral pain assessment with self-reporting in awake, non-verbal, critically ill patients unable to use low-tech augmentative and alternative communication tools. METHODS: Prospective cohort study of intubated or tracheotomized adult, ventilated patients with a RASS (Richmond Agitation Sedation Scale) of -1 to + 1 and inadequate non-verbal communication skills in a surgical intensive care unit of a tertiary care university hospital. For pain assessment, the Behavioral Pain Scale (BPS) was used. Self-reporting of pain was achieved by using an eye tracking device to evaluate the Numeric Rating Scale (NRS) and the pain/discomfort item of the EuroQol EQ-5D-5 L (EQ-Pain). All measurements were taken at rest. RESULTS: Data was collected from 75 patients. Neither the NRS nor the EQ-Pain (r < .15) correlated with the BPS. However, NRS and EQ-Pain were significantly correlated (r = .78, p = < 0.001), indicating the reliability of the self-reporting by these patients. Neither the duration of intubation/tracheostomy, nor cause for ICU treatment, nor BPS subcategories had an influence on these results. CONCLUSIONS: Behavioral pain assessment tools in non-verbal patients who are awake and not in delirium appear unreliable in estimating pain during rest. Before a behavioral assessment tool such as the BPS is used, the application of high-tech AACs should be strongly considered.

Medial augmentation plating of aseptic distal femoral nonunions.

BACKGROUND: Distal femur nonunions are well-recognized contributors to persistent functional disability, with limited data regarding their treatment options. In the current study, we asked whether additional medial augmentation plating is a feasible treatment option for patients with aseptic distal femoral nonunion and intact lateral implants. METHODS: We conducted a single-center, retrospective study including 20 patients treated for aseptic distal femoral nonunion between 2002 and 2017. The treatment procedure included a medial approach to the distal femur, debridement of the nonunion site, bone grafting and medial augmentation plating utilizing a large-fragment titanium plate. Outcome measures were bone-related and functional results, measured by the Hospital for Special Surgery Knee Rating Scale (HSS) and the German Short Musculoskeletal Function Assessment questionnaire (SMFA-D). RESULTS: Eighteen of 20 nonunions showed osseous healing at 8.16 ± 5.23 (range: 3-21) months after augmentation plating. Regarding functional results, the mean HSS score was 74.17 ± 11.12 (range: 57-87). The mean SMFA-D functional index was 47.38 ± 16.78 (range 25.74-71.32) at the last follow-up. Index procedure-associated complications included two cases of persistent nonunion and one case of infection. CONCLUSIONS: According to the assessed outcome measures, augmentation plating is a feasible treatment option, with a high proportion of patients achieving bony union and good functional outcomes and a few patients experiencing complications.

The impact of knee arthrodesis on gait kinematics, muscle activity and patient-reported outcome.

BACKGROUND: The aim of this retrospective study was to analyze gait kinematicsandoutcome parameters after knee arthrodesis. METHODS: Fifteenpatients with a mean follow-up of 5.9 (range0.8-36) years after unilateral knee arthrodesis were included. A 3D gait analysis was performed and compared to a healthy control group of14patients. Comparative electromyography was performed bilaterally at the rectus femoris, vastuslateralis/medialisand tibialis anterior muscles. The assessment further included standardized outcome scores- Lower Extremity Functional Scale (LEFS) andShort Form Health Survey (SF-36). RESULTS: The 3D analysis showed a significantly shortened stance phase (p = 0.000), an extended swing phase (p = 0.000), and an increased time per step (p = 0.009) for the operated side compared with thenonoperatedside. There were statistically significant differences in the extent of movement of the hips, knees and ankles among the operated andnonoperatedsides and the control group. For the mean EMG measurement, no significant difference was found between the healthy control group and the patients with arthrodesis.The average LEFSscorewas 27.5 ± 10.6out of a maximum of 80 points,and the mean physical total scale and mean emotional total scale scores for the SF-36 were 27.9 ± 8.5and 52.9 ± 9.9, respectively. CONCLUSIONS: Arthrodesis of the knee joint causes significant kinematic changes in gait pattern,and patients achieve poor results in subjective and functional outcomes(SF- 36, LEFS).Arthrodesis ensures that the extremities are preserved and can enable walking, but it must be viewed as a severe handicap for the patient.

Rate of progressive healing with a carbon-fiber orthosis in cases of partial union and nonunion after ankle arthrodesis using the Ilizarov external fixator.

BACKGROUND: The Ilizarov fixator is a popular device for treating arthrodesis of the ankle joint in complex situations. However, the therapy can fail, with nonunion or partial union that might not be load stable. There is the possibility of follow-up surgery or extended wearing of the fixator. Full weight bearing with a carbon orthosis remains another treatment option, which has not yet been investigated.The aim of the study was to determine the rate of progress that can be obtained with a carbon orthosis in cases of partial union or nonunion after fixator removal. METHODS: In this retrospective observational study thirty-three patients received a carbon orthosis after fixator removal due to nonunion or partial union. All patients were allowed to walk with the orthosis under full load. The consolidation rate was determined radiologically and compared with the imaging data obtained during the last follow-up. In addition to demographic data, the Foot and Ankle Ability Measure and pain using a numeric rating scale were determined. Nine patients had to be excluded due to insufficient follow-up, and finally n = 24 patients were included in the study. RESULTS: The average duration of fixator use was 21 weeks (range 15-40 weeks), and the total average follow-up after removal of the fixator was 16 months (range 4- 56). For 14 (58.33%) patients, there was a further increase in consolidation with the orthosis after the fixator was removed. CONCLUSION: The results show that if there is only partial union or nonunion, further consolidations can be achieved after the application of a carbon orthosis. In a difficult patient population, using an orthosis should therefore be attempted to avoid unnecessary revision operations.

Development of the Tracheostomy Well-Being Score in critically ill patients.

PURPOSE: Little attention has been given to understanding the experiences and perceptions of tracheostomized patients. This study aimed to measure the impact of tracheostomy on well-being in critically ill patients with the development of the Tracheostomy Well-Being Score (TWBS). METHODS: This is a prospective, monocentric, observational study including critically ill patients with a tracheostomy without delirium. A 25-item questionnaire with items from six categories (respiration, coughing, pain, speaking, swallowing, and comfort) was used to select the 12 best items (two per category) to form the TWBS score after testing on two consecutive days. Item selection secured (1) that there were no skewed response distributions, (2) high stability from day 1 to day 2, and (3) high prototypicality for the category in terms of item-total correlation. RESULTS: A total of 63 patients with a mean age of 56 years were included. The 12 items of the TWBS were characterized by a high retest reliability (τ = 0.67-0.93) and acceptable internal consistency. The overlap with the clinician rating was low, suggesting that acquiring self-report data is strongly warranted. CONCLUSION: With the TWBS, an instrument is available for the assessment of the subjective effects a tracheostomy has on in critically ill patients. The score potentially offers a chance to increase well-being of these patients. Additionally, this score could also increase their quality of life by improving tracheostomy and weaning management.

First experiences of communication with mechanically ventilated patients in the intensive care unit using eye-tracking technology.

INTRODUCTION: Eye-tracking (ET) may be a novel tool for communication with intubated and mechanically ventilated critically ill patients. We hypothesized that ET could be learned fast and be used successfully by intensive care unit (ICU) and intermediate care (IMC) patients with artificial airways for communication. METHODS: Including all patients with mechanical ventilation via oral intubation or tracheostomy, who were at least 18 years of age with a score of -1 to +1 points on the Richmond agitation-sedation scale and a history of ventilation for more than 48 h. A commercially available ET was used. The investigations were performed by a physician with the support of a psychologist following a standardized study protocol. RESULTS: During a 4-week period a total of 11 patients completed all of the five steps of our study protocol. The time to complete our study protocol was 64 ± 23.8 min (range 43-125 min) with a mean of 1.5 ± 0.9 sessions (range 1-4 sessions). Seven patients (63.6 %) could run through all of the five steps within their first session. All patients (100%) preferred the gaze fixation technique to control the ET to the wink control. CONCLUSION: Mechanically ventilated ICU and IMC patients are able to use ET in a very short time for communication to indicate their basic needs, answer rating scales and pain scores as well as questionnaires about quality of life and self-esteem.Implications for rehabilitationCOMFORT - The novel communication device improves the patients' ability to communicate with the attending physicians, physiotherapists and nurses in order to provide a tailored rehabilitation approach.COMPLIANCE - The use of the eye-tracking technology enables the patients to communicate special needs and fears during the course of the rehabilitation.COMPLICATIONS - The eye-tracking technology enables the attending rehabilitation team to earlier detect complications (e.g. pain, depression) during the course of the rehabilitation.

The Use of the Ilizarov Fixator for the Treatment of Open and Closed Tibial Shaft and Distal Tibial Fractures in Patients with Complex Cases.

INTRODUCTION: Open and closed fractures of the tibial shaft or distal tibia can be challenging for surgeons to treat if the fractures are accompanied by aggravating conditions, such as various accompanying diseases, pronounced soft tissue injuries, osteomyelitis, and/or noncompliance. The aim of this retrospective study was to present our approach and results with the Ilizarov fixator as a treatment option for such individually complex cases. MATERIALS AND METHODS: Between 2005 and 2018, 20 patients were treated with the Ilizarov fixator for fractures of the tibial shaft/distal tibia. The indication for this was a 2nd- to 3rd-degree open fracture in 10 patients, a 1st-degree open fracture in one patient, and closed fractures in 9 patients. Aggravating conditions included soft tissue injuries, osteomyelitis, leg deformities, multiple traumas, smoking, alcohol/drug abuse, and obesity (BMI > 60). In addition to demographic data, the time of fixator treatment, complications, and the endpoint of consolidation were evaluated retrospectively. RESULTS: The mean time of fixator treatment was 29 (range 15-65) weeks. Complete fracture consolidation was achieved in 13 patients (65%) with the Ilizarov fixator. The mean follow-up period after fixator removal was 36 (range 2-186) months in 14 patients. Five patients with complete consolidation were lost to further follow-up. One patient was amputated. In six patients without union, internal osteosynthesis was carried out. CONCLUSION: The use of the Ilizarov fixator is a treatment option for individual high-risk patients with complicating courses but should be seen as a salvage procedure due to the high complication rate and long treatment process.

Injuries after Forklift Trucks Accidents - Injury Patterns, Therapy and Outcome in the Context of the Statutory Accident Insurance. / Gabelstaplerunfälle ­ Verletzungsmuster, Therapie und Outcome im berufsgenossenschaftlichen Kontext.

INTRODUCTION: The use of forklift trucks during work has a high accident potential. The aim of this study is to describe injury patterns, treatment and outcome after forklift truck accidents in the context of the employers' liability insurance association. METHODS: Retrospective data collection of all cases between 2004 and 2019. Excluded were patients < 18 years, without follow-up or with definitive external treatment. Trauma mechanism, injury patterns and distribution, treatment, complications, time of incapacity for work, return to work and impairment of earning capacity were recorded. RESULTS: Of 109 patients with 110 injuries, 52.7% showed isolated injuries and 47.3% combined injuries, which affected the lower extremity in 95 cases. There were fractures in 85.5%, including 32.7% in open form. The mean length of stay was 29.1 days (range 1 - 129); an indication for surgery was seen in 80.9%. Surgical treatment required an average of 3 interventions, with significantly more operations for soft tissue closure than for the fractures (p ≤ 0.023). Amputations were necessary in 8 cases; complications occurred in 29.1%. Return to work was possible in 90%, after a mean period of incapacity for work of 33.6 weeks. A total of 40% showed a pensionable impairment of earning capacity. CONCLUSION: Accidents with forklift trucks result in complex lower extremities injuries with the need of multi-stage treatment and show relatively high complication rates. A return to work is often possible after a long period of convalescence, and a pensionable impairment of earning capacity often persists.

Approach to the basic needs in patients on invasive ventilation using eye-tracking devices for non-verbal communication.

PURPOSE: To analyze the feasibility of eye-tracking (ET) devices as a communicative approach to the basic needs (BN) of intensive care unit (ICU) and invasively ventilated nonverbal patients. METHODS: Prospective, monocentric, and observational study including all patients without delirium, with an endotracheal tube or tracheostomy tube, with a history of invasive ventilation for more than 48 h, and inadequate nonverbal communication skills. The investigation was performed with commercially available ET devices (Tobii Dynavox I-15+) to express BN of ICU patients following a standardized 30-item yes-or-no questionnaire. RESULTS: A total of 64 patients with a mean age of 58.6 years were included. The main diagnoses for ICU admission were major trauma (43.6%), sepsis (21.8%), and acute abdomen (15.6%). Pain during repositioning (69%), thirst (69%), sleep disorders (66%), fatigue (64%), and anxiety regarding the lifelong need for assistance (64%) were the main problems reported by the patients. However, most of the patients described expectations of health improvement (78%), good family support (66%), and an improvement in quality of life due to the use of ET devices (67%). CONCLUSION: The use of ET in selected ICU patients with impaired communication is feasible, allowing them to express their BN. Apart from knowing the patients' individual BN, the results of our BN questionnaire may provide guidance for improvement measures in the care of patients in the ICU who are unable to speak. We believe that ET is useful for inquiring about and expressing BN and, therefore, may be capable of improving patient-medical team interactions and patient satisfaction.

Factors Associated With Major Complications and Mortality During Hospitalization in Patients With Ankylosing Spondylitis Undergoing Surgical Management for a Spine Fracture.

STUDY DESIGN: Retrospective study. OBJECTIVES: To analyze factors associated with major complications (MC) in patients with ankylosing spondylitis (AS) undergoing surgical management for a spine fracture. METHODS: Included were all persons with spine fractures and AS in a teriary health care center between 2003 and 2019. Clinical data and MC were characterized with descriptive characteristics. Multivariable analyses were used to find factors associated with MC. RESULTS: In total, 174 traumatic fracture incidents in 166 patients with AS were included, with a mean patient age of 70.7 ± 13.1 years. The main reason for spine fracture was minor trauma (79.9%). Spinal cord injuries (SCI) were described in 36.7% of cases. The majority of patients (54.6%) showed more than one fracture of the spine, with cervical fractures being the most common (50.5%). Overall, the incidences of surgical site infection, implant failure, nosocomial pneumonia (NP), and mortality were 17.2%, 9.2%, 31%, and 14.9%, respectively. ICU stay > 48 hours was associated with MC (including death). Posterior approach for spondylodesis, ICU stay > 48 hours and cervical SCI were related to MC (excluding death). Age > 70 years, NP and Charlson comorbidity index > 5 points were associated with in-hospital mortality. CONCLUSIONS: Patients with AS and surgical treatment of spine fractures are at high risk for MC. Therefore, our results might give physicians better insight into the incidence and sequelae of major complications and therefore might improve patient and family expectations.

Tibiocalcaneal arthrodesis using the Ilizarov fixator in compromised hosts: an analysis of 19 patients.

INTRODUCTION: Salvage of joint destruction of the tibiotalar and subtalar joint with necrosis or infection of the talus in compromised hosts is a challenging problem. In these cases, tibiocalcaneal arthrodesis using the Ilizarov external fixator represents a possible alternative to amputation. This retrospective study presents the results and complications of this salvage procedure. MATERIALS AND METHODS: Between 2005 and 2015, 19 patients were treated with tibiocalcaneal arthrodesis using the Ilizarov external fixator. Ten patients received tibiocalcaneal arthrodesis due to an acute or chronic infection with joint destruction. The other nine patients presented posttraumatic necrosis of the talus or Charcot arthropathy. In addition to demographic data, the time spent in the fixator, the major and minor complications and the endpoint of the consolidation were evaluated retrospectively. Furthermore, clinical outcomes were measured using the modified American Orthopedic Foot and Ankle Society (AOFAS) score. RESULTS: The average time spent in the fixator was 22 (range 14-34) weeks. The average follow-up in 17 patients was 116 (range 4-542) weeks. Two patients were lost to follow-up. Complete osseous consolidation was achieved in 14 out of 19 patients. One patient presented partial consolidation, and in four patients, pseudarthrosis could be detected. The mean modified AOFAS score at the final follow-up was 53 out of 86 possible points. CONCLUSION: Tibiocalcaneal arthrodesis using the Ilizarov fixator is a possible salvage procedure even in compromised hosts. However, the healing rates are below the rates reported in the literature for tibiotalar arthrodesis in comparable clinical situations.

The use of predefined scales and scores with eye-tracking devices for symptom identification in critically ill nonverbal patients.

BACKGROUND: Eye tracking (ET) may be a novel tool to enable nonverbal communication. We hypothesized that ET could be used successfully by intensive care unit (ICU) patients with artificial airways to express their levels of pain and mood, quality of life, and self-esteem with predefined scales and scores. METHODS: Prospective, monocentric, observational study, including patients with an endotracheal tube or tracheostomy tube and a history of mechanical ventilation for more than 48 hours without delirium, and inadequate nonverbal communication skills. The ICU patients' pain was assessed with a numeric rating scale, their mood was tested with a smiley analog scale. Quality of life and self-esteem were measured with the European quality of life-5 dimensions-5 levels-score and the visual analog self-esteem scale. RESULTS: A total of 75 patients with a mean age of 58.3 years were included. Main diagnoses for ICU admission were major trauma (45.3%), nonabdominal sepsis (22.6%), and acute abdomen (13.3%). Patients showed moderate levels of pain and sadness with a median of 4 (interquartile range, 3-5.5) on the numeric rating scale and a median of 4 (interquartile range, 3-4) on the smiley analog scale. The general health status on the European quality of life-5 dimensions-5 levels-score was rated as poor. Reporting on the visual analog self-esteem scale, most of the included patients felt trapped (90.7%) and not confident (72%), were frustrated (64%) or did not feel understood (56%). However, despite their severe illness, many patients classified themselves as intelligent (30.6%), not mixed up (38.6%), outgoing (38.6%), and optimistic (44%). CONCLUSION: Eye tracking enables symptom identification in critically ill voiceless patients with impaired communication options. The results of our study may provide guidance for improvement measures in the care of voiceless ICU patients. We believe that ET is useful for symptom identification and therefore may be capable of improving patient-medical team interaction and patient satisfaction.

Impact of surgical site infection on patients' outcome after fixation of tibial plateau fractures: a retrospective multicenter study.

BACKGROUND: Surgical site infection (SSI) occurs in 3-10 % of patients with surgically treated tibial plateau fractures. This study aimed to evaluate the impact of SSI on patients' outcome after fixation of tibial plateau fractures. METHODS: We conducted a retrospective multicenter study in seven participating level I trauma centers between January 2005 and December 2014. All participating centers followed up with patients with SSI. In addition, three centers followed up with patients without SSI as a reference group. Descriptive data and follow-up data with patient-reported outcome scores (Knee Injury and Osteoarthritis Outcome Score [KOOS] and Lysholm knee scoring scale score) were evaluated. RESULTS: In summary, 287 patients (41 with SSI and 246 without SSI; average 50.7 years) with an average follow-up of 75.9 ± 35.9 months were included in this study. Patients with SSI had a significantly poorer overall KOOS (KOOS5) (48.7 ± 23.2 versus [vs.] 71.5 ± 23.5; p < 0.001) and Lysholm knee scoring scale score (51.4 ± 24.0 vs. 71.4 ± 23.5; p < 0.001) than patients without SSI. This significant difference was also evident in the KOOS subscores for pain, symptoms, activities of daily living (ADL), and quality of life (QoL). SSI remained an important factor in multivariable models after adjusting for potential confounders. Clinically relevant differences in the KOOS5 and KOOS subscores for symptoms, pain, and ADL were found between those with SSI and without SSI even after adjustment. Furthermore, the number of previous diseases, Arbeitsgemeinschaft für Osteosynthesefragen Foundation (AO) C fractures, and compartment syndrome were found to be additional factors related to poor outcome. CONCLUSIONS: Compared to previous studies, validated patient-reported outcome scores demonstrated that the impact of SSI in patients with surgically treated tibial plateau fractures is dramatic, in terms of not only pain and symptoms but also in ADL and QoL, compared to that in patients without SSI.

Risk Factors for Deep Surgical Site Infection in Patients With Operatively Treated Tibial Plateau Fractures: A Retrospective Multicenter Study.

OBJECTIVES: To identify the potential controllable risk factors for surgical site infection (SSI). DESIGN: A retrospective cohort study. SETTING: Seven Level-I trauma centers. PATIENTS/PARTICIPANTS: Patients with OTA/AO 41 B or C tibial plateau fractures (n = 2106). INTERVENTION: Various surgical treatments for tibial plateau fractures. MAIN OUTCOME MEASUREMENTS: The primary outcome was SSI after the index operation. The secondary outcomes were the risk factors for SSI, identified using backward stepwise generalized multiple regression analysis. RESULTS: Of the 2106 enrolled patients, 94 had deep SSIs. The average SSI rate was 4.5%. Fracture morphology revealed type B injuries in 57.5% and type C in 42.5% of the patients. Univariate regression analysis revealed that several factors, namely, number of comorbidities [>6 vs. none; odds ratio (OR) 8.01, 95% confidence interval (CI) 2.8-22.8, P < 0.001], diabetes mellitus (OR 3.5, 95% CI 2.0-6.3, P < 0.001), high body mass index (OR 1.3, 95% CI 1.1-1.6, P = 0.001), OTA/AO fracture type C (OR 5.6, 95% CI 3.3-9.5, P < 0.001), compartment syndrome (OR 9.1, 95% CI 5.7-14.8, P < 0.001), and open fracture (OR 6.6, 95% CI 3.7-11.7, P < 0.001), were associated with a significantly higher SSI risk. Analysis of microbial sensitivity tests revealed that 55.1% of the pathogens were resistant to perioperative antibiotic prophylaxis. CONCLUSIONS: Most of the identified risk factors cannot be controlled or are subject to other factors that are difficult to control. However, our data suggest that the choice of perioperative antibiotic prophylaxis may influence the rate of SSI. This possibility should be investigated in a prospective randomized controlled trial. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Spinal Cord Injury With Tetraplegia in Young Persons After Diving Into Shallow Water: What Has Changed in the Past 10 to 15 Years?

STUDY DESIGN: Retrospective, monocentric, observational study in a tertiary health care center. OBJECTIVES: To analyze prehospital and clinical findings, complications, neurological improvement and follow-up in a young person cohort with spinal cord injury (SCI) and tetraplegia according to the American Spinal Injury Association (ASIA) Impairment Scale (AIS) A to D after diving into shallow water. METHODS: Included were all persons younger than 50 years with SCI after head-first diving into shallow water between June 2001 and June 2019. All persons with SCI were divided into complete tetraplegia (AIS A) and incomplete tetraplegia (AIS B, C, and D) to test differences. RESULTS: A total of 59 males (98.7%) and 1 female with a mean age of 27.7 years suffered an SCI. Alcohol use was documented in 25 cases (41.7%). At the time of admission, 33 people (55%) showed a complete tetraplegia (AIS A) and 27 showed an incomplete tetraplegia with 8 AIS B (13.3%), 15 AIS C (25%), and 4 AIS D (6.7%). At the time of discharge, people with initially complete tetraplegia showed a significant improvement from admission to discharge (P ≤ .004). Persons with incomplete tetraplegia were more likely to improve their neurological status compared with complete tetraplegia patients (P ≤ .001). Especially persons with complete tetraplegia suffered from typical SCI-related problems and complications. CONCLUSIONS: People with SCI and tetraplegia at the time admission show neurological improvement in 50% of the cases with an overall better outcome in persons with incomplete tetraplegia. The surgical treatment of SCI within 24 hours seems to be associated with a better neurological outcome and a lower level of tetraplegia. The incidence of SCI caused by diving into shallow water remains stable without a significant change, especially in high-risk groups. More education and prevention programs are necessary to avoid these injuries.

Microbial findings and the role of difficult-to-treat pathogens in patients with periprosthetic infection admitted to the intensive care unit.

Little is known about patients with Periprosthetic Joint Infection (PJI) admitted to the Intensive Care Unit (ICU). The purpose of this study was threefold: i) To report the microbiological findings of ICUpatients with PJI. ii) To compare the clinical data between Difficult-To-Treat (DTT) and non-DTT PJI. iii) To identify risk factors for mortality. This is a retrospective study from a tertiary healthcare center in Germany from 2012-2016. A total of 124 patients with 169 pathogens were included. The most common bacteria were Staphyloccous aureus (26.6%), Staphyloccus epidermidis (12.4%), Enterococci ssp. and Escherichia coli (respectively 9.4%). DTT PJI was diagnosed in 28 patients (22.6%). The main pathogens of DTT PJI were Staphylococus epidermidis (14.5%), Escherichia coli (12.7%), Staphylococcus aureus and Candida spp. (respectively 9.1%). Polymicrobial PJI, number of pathogens, ICU stay and mortality were significantly differrent between DTT PJI and non-DTT PJI (p≤0.05). Multivariate logistic regression identified prolonged ICU stay and DTT PJI as risk factors for mortality. In conclusion, we suggest, that the term of DTT pathogens is useful for the intensivist to assess the clinical outcome in ICU-patients with PJI.

Effect of fracturoscopy on the incidence of surgical site infections post tibial plateau fracture surgery.

PURPOSE: Surgical treatment of tibial plateau fracture (TPF) is common. Surgical site infections (SSI) are among the most serious complications of TPF. This multicentre study aimed to evaluate the effect of fracturoscopy on the incidence of surgical site infections in patients with TPF. METHODS: We performed a retrospective multicentre study. All patients with an AO/OTA 41 B and C TPF from January 2005 to December 2014 were included. Patients were divided into three groups: those who underwent arthroscopic reduction and internal fixation (ARIF), and those who underwent open reduction and internal fixation (ORIF) with fracturoscopy, and those treated with ORIF without fracturoscopy. The groups were compared to assess the effect of fracturoscopy. We characterised our cohort and the subgroups using descriptive statistics. Furthermore, we fitted a logistic regression model which was reduced and simplified by a selection procedure (both directions) using the Akaike information criterion (AIC). From the final model, odds ratios and inclusive 95% confidence intervals were calculated. RESULTS: Overall, 52 patients who underwent fracturoscopy, 48 patients who underwent ARIF, and 2000 patients treated with ORIF were identified. The rate of SSI was 0% (0/48) in the ARIF group and 1.9% (1/52) in the fracturoscopy group compared to 4.7% (93/2000) in the ORIF group (OR = 0.40, p = 0.37). Regression analyses indicated a potential positive effect of fracturoscopy (OR, 0.65; 95% CI, 0.07-5.68; p = 0.69). CONCLUSION: Our study shows that fracturoscopy is associated with reduced rates of SSI. Further studies with larger cohorts are needed to investigate this. LEVEL OF EVIDENCE: Level III.
