RESUMO
For femoral fractures of the trochanteric region in children and adolescents, only two mechanisms have been identified to cause a fracture of the proximal femur: high-energy trauma or predisposing bone pathologies with inadequate trauma (e.g., simple fall, movement). We identified 20 patients between 1993 and 2018 with a trochanteric fracture under the age of 18 (12 males; 8 females; mean age, 12 years; range, 4-17 years) who were treated operatively at our department. The mean follow-up of all patients was 50.06 months. All 20 patients were treated operatively. Complications occurred after a mean time of 6.27 months (range, 0.47 to 12.07 months) in two patients. Harris Hip Score was evaluated in all patients with a mean score of 94.16 (range 11 to 100). Eighty-five percent of the patients reached an excellent clinical outcome after treatment. Trochanteric femoral fractures in children and adolescents are very rare accounting for only 1% of all trochanteric fractures. Excellent long-term results can be achieved with an adequate fracture reduction.Conclusion: Physicians treating pediatric trauma have to be aware of other predisponding diseases when low-energy trauma leads to a trochanteric fracture as in this study, 50% of the trochanteric fractures were associated with bone pathologies. What is Known: ⢠Trochanteric femoral fractures in children and adolescents are very rare ⢠In all patients with trochanteric femoral fractures, malignancies have to be ruled out What is New: ⢠Awareness of an underlying bone pathology in a high number of cases ⢠Awareness for necessity of a good fracture reduction leading to highly satisfactory results.

This study describes the outcome of supracondylar humerus fractures in children using crossed K-wires after closed or open reduction with the medial, lateral or bilateral approach. Patients treated between January 2000 and December 2019 were classified according to the Von Laer classification, complications were classified according to the Sink classification and clinical outcomes were classified according to modified Flynn criteria. In total, 364 patients with a mean age of 5.23 ± 2.45 years were included. The majority were type IV fractures (156; 42.9%) and 94 (60.3%) needed an open reduction for which the medial approach (53; 56.4%) was predominantly used. Overall, of 50 complications (31 using closed reduction, 19 open reduction), 17/50 (34%) needed revision surgery. An excellent clinical outcome was achieved in 348/364 (95.6%) patients. The approach used for open reduction as such had no influence on the complication rate or clinical outcome. For severely displaced fractures, the data showed that an open approach for crossed K-wires tended to result in fewer complications and better clinical outcomes than a closed reduction. If an open reduction is indicated, the required approach (medial, lateral or bilateral) should be primarily selected according to the requirements of the fracture pattern and eventual cosmetic considerations.
RESUMO
BACKGROUND: An alarming increase in domestic violence was reported during the COVID-19 pandemic worldwide. The aim of this study is to investigate changes in the frequency and the nature of domestic violence at the largest level-one trauma center in Austria. METHODS: All patients admitted to our institution with domestic violence injuries 15 months before and after the beginning of the COVID-19 pandemic were included. For our analysis, we investigated the frequency of trauma patients after domestic violence in relation to all other trauma patients. Furthermore, age, sex, citizenship, injury pattern, injured body regions, injury mechanism, offender-victim relationship, and hospitalization rate were also analyzed. RESULTS: Among all trauma patients admitted, the ratio of patients who reported domestic violence injuries increased from 0.465% to 0.548% since the start of the pandemic. In addition, out of the total count of domestic violence victims, the percentage of Austrian citizens increased significantly from 51.2% to 60.6% (p = 0.016). All other parameters showed no significant changes pre and post-pandemic. CONCLUSION: The COVID-19 pandemic contributed to a relative increase in patients with domestic violence injuries at the largest trauma unit in Austria, along with a significant increase among Austrian citizens. The remaining study parameters did not differ significantly, indicating that the frequency changed during the pandemic but not the underlying pattern of domestic violence.
RESUMO
The aim of this retrospective study was to present an epidemiological overview of paediatric nonelectric-scooter-related injuries, focusing on changes in injury mechanism and frequency. A retrospective, descriptive data analysis at a Level I trauma centre, including patients aged from 0 to 18 years injured by riding nonelectric scooters, was performed. The observation period ranged from January 2015 to December 2022. The total study population consisted of 983 (mean age: 7.9 ± 4.0 years) children and adolescents, with most patients being male (800/983; 81.4%). The frequency of nonelectric scooter injuries was relatively consistent over the observation period. Patients sustained mostly minor injuries (lacerations, bone contusions, sprains) (527/983; 53.6%), followed by head injuries (238/983; 24.5%), limb fractures (166/983; 16.9%) and trunk injuries (52/983; 5.3%). However, a few patients sustained severe injuries, including skull fractures (7/238; 2.9%), intracranial haematoma (4/238; 1.7%) or lacerations of abdominal organs (4/52; 7.7%). This study presented a consistently high frequency of scooter injuries in children. Children under 15 years were the most affected by scooter-related injuries. Although most injuries were minor, serious injuries occurred that should not be underestimated. Hence, we emphasise the use of protection gear and recommend raising awareness among parents and children.
RESUMO
The most common cause leading to supracondylar humerus fractures in children is falling onto an outstretched arm. A correlation between fall height and fracture severity may be assumed but has not yet been described. The aim of this study was to show that fracture severity increases with fall height. Furthermore, the correlation between fracture severity and outcome was examined. A total of 971 children with supracondylar humerus fractures between January 2000 and December 2019 were included in this study. The correlations between fall height and fracture severity and between fracture severity and outcome were assessed. Increasing fall height correlates with fracture severity (p < 0.001; r = 0.24). Furthermore, the incidence of complications increases with fracture severity and a correlation was present accordingly (p < 0.001; r = 0.28). A total of 30 (3.1%) patients showed limitations in range of motion and/or persistent neurologic deficits at the latest follow-up. Type I fractures rarely lead to subsequent limitations. The correlation between increasing fall height and fracture severity was significant. Furthermore, children with type III and IV supracondylar fractures are more likely to develop complications or restrictions in movement than children with type I and II fractures. Hence, the initial fall height may be an indirect indicator of a more or less favorable outcome.
RESUMO
The COVID-19 pandemic and the resulting restrictions led to a reduced number of surgeries. This study examines its impact on the course of treatment and clinical outcome of surgically treated paediatric upper limb fractures during that specific period. This retrospective cohort study evaluated all children aged 0-18 years presenting with an upper limb fracture treated surgically at the level 1 trauma centre of the University Clinic of Orthopaedics and Trauma Surgery of Vienna within lockdown from 16 March to 29 May 2020 (definition applied through corresponding legislation) compared to the same period from 2015 to 2019. A total number of 127 children (m:63; f:44) were included. The lockdown did not lead to a significant increase in complications during and after initial surgery. Time until removal of implant was not significantly prolonged (p = 0.068; p = 0.46). The clinical outcome did not significantly differ compared to previous years. The experience of a level 1 trauma centre showed that despite reduced surgical capacity during the COVID-19 pandemic, no negative differences concerning course of treatment and clinical outcome of surgically treated paediatric upper limb fractures were present. These findings are still of importance since the COVID-19 pandemic continues and several countries in Central Europe are currently under their fourth lockdown.
RESUMO
BACKGROUND: This study examined the effect of the COVID-19 pandemic and the resulting decrease in the incidence of various categories of injuries, with the main focus on fractures and mild traumatic brain injuries in a paediatric population. METHODS: This retrospective cohort study evaluated all children from 0 to 18 years of age presenting with an injury at the level 1 trauma centre of the University Clinic of Orthopaedics and Trauma Surgery in Vienna during the lockdown from 16 March to 29 May 2020 compared to records over the same timeframe from 2015 to 2019. RESULTS: In total, 14,707 patients with injuries were included. The lockdown did not lead to a significant decrease in fractures but, instead, yielded a highly significant increase in mild traumatic brain injuries when compared to all injuries that occurred (p = 0.082 and p = 0.0001) as well as acute injuries (excluding contusions, distortions and miscellaneous non-acute injuries) (p = 0.309 and p = 0.034). CONCLUSIONS: The percentage of paediatric fractures did not decrease at the level 1 trauma centre, and a highly significant proportional increase in paediatric patients with mild traumatic brain injuries was observed during the COVID-19 lockdown. Therefore, medical resources should be maintained to treat paediatric trauma patients and provide neurological monitoring during pandemic lockdowns.

INTRODUCTION: Fractures of the proximal femur are a significant cause of mortality and morbidity in the elderly population. Yet predictive marker of unfavourable prognosis are still lacking. Calcium phosphate product is a marker of osteo-renal dysregulation. This study investigated the role of serum calcium phosphate product (SCPP) levels as a prognostic parameter for outcome in those patients. PATIENTS AND METHODS: A total of 3577 consecutive patients with diagnosed fractures of the proximal femur were included in our study (72.5% females). SCPP was divided into tertiles: <1.92mmol(2)/l(2), 1.93-2.38mmol(2)/l(2) and >2.39mmol(2)/l(2). Data collection was performed prospectively and statistical evaluation was performed retrospectively. RESULTS: Mean follow up in our study group was 11.0±0.3 months. The mean age of our study group was 79.0 years (SEM ±14 years). To facilitate analysis, patients were divided in two groups: ≤84 years (64.4%) and ≥85 years (35.6%), and mortality <12 months was 12.4% (n=445). In our study population higher SCPP levels ad admission were associated with a markedly elevated mortality. In a multivariate logistic regression model adjusted for age and sex, plasma creatinine and haemoglobin at admission caused a 1.3 (CI: 1.01-1.6) for SCPP 1.93-2.38mmol(2)/l(2), and a 1.6 (CI: 1.2-2.0) for SPP >2.39mmol(2)/l(2) fold increase in overall mortality compared to patients with baseline SCPP levels (<1.92mmol(2)/l(2)) as reference category. CONCLUSION: Those findings in our study population with 3577 patients over a period of 20 years proved to be, that serum Ca levels may be a good predictor for mortality in patients with fracture of the proximal femur. Further studies are required to evaluate whether these high risk patients might benefit from specific therapeutic measurements. This prognostic factor may help to increase the outcome of elderly patients with a fracture of the proximal femur.

BACKGROUND: Bite wounds are among the commonest types of trauma to which man is the subject. They account for 5 % of the total traumatic wounds evaluated in the emergency department (ED) and approximately 1 % of all the ED visits. Early estimation of infection risk, adequate antibiotic therapy and if indicated surgical treatment are the cornerstones of successful cure of bite wounds. METHODS: A total of 5248 consecutive trauma patients were collected prospectively and analysed retrospectively over a period of 15 years in this study at a level I trauma centre, Department of Trauma Surgery, Medical University of Vienna, Austria. RESULTS: The mean age was 33.8 years (range 0-97), 2620 (49.9 %) were male and 2628 (50.1 %) were female individuals. In our study population, a total of 2530 dog bites (48.2 %), 930 cat bites (17.8 %), 357 other animal bites (6.8 %), 426 human bites (8.1 %) and 1005 human self-bites (19.2 %) have been observed. A total of 995 wounds (19.0 %) have been infected. Surgery was done in 132 wounds (2.5 %). CONCLUSION: We could show a six times higher infection rate of cat bites compared to dog bites. Human bites showed a total infection rate of 8.2 %. Observed infection rate of puncture wounds and wounds greater than 3 cm was 1.5 times higher than for all other wounds in the present study. Total infection rates within 24 h to antibiotic administration was 29.3 %, compared to 65.0 % < 48 h and 81.1 % < 72 h. Time interval also influenced the overall outcome showing a 2.6 increase in acceptable and 1.3 increase in poor outcome after 72 h.

INTRODUCTION: Hip fractures are a significant cause of mortality and morbidity in the elderly. This study investigated the relationship between initial haemoglobin (Hb) levels and a prognostic parameter for outcome in those patients. PATIENTS AND METHODS: A total of 3595 consecutive patients with diagnosed hip fractures were included in our study (72.2% females). Anaemia was defined according to WHO criteria, with according subgroups mild, moderate and severe anaemia. Data collection was performed prospectively and statistical evaluation was performed retrospectively. RESULTS: Mean follow up in our study group was 11.2 ± 0.3 months. The mean age of our study group was 78.5 years (SEM ± 0.2 years). To facilitate analysis, patients were divided in two groups: ≤ 84 years (60.1%) and ≥ 85 years (39.9%). Mortality <12 months was 12.2% (n = 439). In our study population lower Hb levels ad admission were associated with a markedly elevated short-term mortality. In a multivariate logistic regression model adjusted for age and sex, mild anaemia at admission caused a 1.5 (CI: 1.1-1.9), moderate anaemia a 2.6 (95 CI: 2.0-3.4), and severe anaemia a 3.6 (CI: 1.8-6.9) fold increase in three months mortality compared to patients without anaemia. Total lymphocyte count (1.2 ± 0) did not show any differences between the subgroups. CONCLUSION: Those findings in our study population with 3595 patients over a period of twenty years have proven that initial Hb levels are a useful and cost effective parameter to predict mortality in elderly patients with a hip fracture. This prognostic factor may help to increase the outcome of elderly patients with a hip fracture.

AIM: To assess the clinical effects and the morphological grade of nerve compression. METHODS: In a prospective single-center randomized, open study we assessed the clinical effects and the morphological grade of nerve compression during 20 min of either a silicon ring (group A) or pneumatic tourniquet (group B) placement variantly on the upper non-dominant limb in 14 healthy human volunteers. Before and during compression, the median and radial nerves were visualized in both groups by 3 Tesla MR imaging, using high resolutional (2.5 mm slice thickness) axial T2-weighted sequences. RESULTS: In group A, Visual analog pain scale was 5.4 ± 2.2 compared to results of group B, 2.9 ± 2.5, showing a significant difference (P = 0.028). FPS levels in group A were 2.6 ± 0.9 compared to levels in group B 1.6 ± 1, showing a significant difference (P = 0.039). Results related to measureable effect on median and radial nerve function were equal in both groups. No undue pressure signs on the skin, redness or nerve damage occurred in either group. There was no significant difference in the diameters of the nerves without and under compression in either group on T2 weighted images. CONCLUSION: Based on our results, no differences between narrow and wide tourniquets were identified. Silicon ring tourniquets can be regarded as safe for short time application.
RESUMO
Trauma of the infant or juvenile spine is a very rare occurrence (less than 2%). Nevertheless, it is almost always dramatic. In 21 years 1630 patients with spinal cord injuries were treated. Of these, 21.7% (357 patients) had injuries in the area of the cervical spine. 23 patients (1.4%) were younger than 17.5 years, 8 of them were younger than 10 years. In 10 cases the cause was a traffic accident, in 7 cases it was a jump in too shallow water. In 4 times other leisure activities were the cause. A fall from a window sill and a falling tree were further reasons. Neck segment C0 to C3 was involved eight times, segment C3 to C7/Th1 was involved 15 times. The average age of the group with injuries in C0 to C3 was 5.6 years, in the group with injuries of segments C3 to C7/Th1 it was 15.8 years. In 11 cases the trauma caused complete tetraplegia, in six cases the paralysis was partial. In six further cases no neurological deficit occurred. 14 cases were treated surgically, six were treated conservatively. Four children younger than 10 years with complete tetraplegia died. In seven cases tetraplegia persisted; out of six patients with incomplete neurological deficit three improved and three patients recovered completely.

BACKGROUND: The purpose of this study was to determine whether different forms of stabilization for open femur fractures can be performed without influencing outcome, in particular infection and delayed unions/nonunions. Although the traditional management of these injuries is external fixation, a trend toward definitive stabilization techniques has evolved in the current literature. METHODS: All open fractures of the femur shaft and the distal femur presenting to our urban Level I trauma center during a 10 year period were reviewed. A total of 40 patients (41 fractures) were initially treated at the above institution within 6 h of injury. All patients underwent emergent wound irrigation, debridement, and antibiothic theraphy. The method of fracture immobilization was left to the discretion of the attending trauma surgent. Study population consited of 12 (29 %) GI, 10 (25 %) GII, and 19 (46 %) GIII fractures. RESULTS: Initially, fracture management was performed with external fixation (EF) 19 (43.2 %), intramedullary nailing (IM) 18 (38.6 %), plating (PL) 3 (6.8 %), screw fixation (SF) 1 (2.3 %) and without treatment 4 (9.1 %). In all, 3 (6.8 %) fractures were complicated by infection, 7 (15.9 %) had implant failure, and 5 (11.4 %) developed delayed union. CONCLUSIONS: Using external fixation in acute fracture treatment for open femur fractures is a safe and effective surgical technique. Based on our results, external fixation might be superior to intramedullary nailing or plating when evaluating outcome parameters and complications.

AIM: To investigate several complications like persistent radial head dislocation, forearm deformity, elbow stiffness and nerve palsies, associated with radial head fractures. METHODS: This study reviewed the clinical records and trauma database of this levelâ Iâ Trauma Center and identified all patients with fractures of the radial head and neck who where admitted between 2000 and 2010. An analysis of clinical records revealed 1047 patients suffering from fractures of the radial head or neck classified according to Mason. For clinical examination, range of motion, local pain and overall outcome were assessed. RESULTS: The incidence of one-sided fractures was 99.2% and for simultaneous bilateral fractures 0.8%. Non-operative treatment was performed in 90.4% (n = 947) of the cases, surgery in 9.6% (n = 100). Bony union was achieved in 99.8% (n = 1045) patients. Full satisfaction was achieved in 59% (n = 615) of the patients. A gender related significant difference (P = 0.035) in Mason type distribution-type III fractures were more prominent in male patients vs type IV fractures in female patients-was observed in our study population. CONCLUSION: Mason typeâ Iâ fractures can be treated safe conservatively with good results. In type II to IV surgical intervention is usually considered to be indicated.
RESUMO
BACKGROUND: Spine injuries, a common component in polytrauma, are relatively rare in pediatric patients. Previous studies mainly described injuries to the cervical region, whereas information of injury patterns to the thoracic and lumbosacral region lack in the current literature. The aim of this study was to determine the incidence and characteristics of polytraumatized children and associated spine injuries in different pediatric development ages. METHODS: A cohort review of all pediatric patients with the diagnosis of polytrauma and associated spine injury, admitted to a urban Level I trauma center, was conducted over an 18-year period from January 1992 to December 2010. Patients were stratified into four developmental age groups: infants/toddlers (age 0-4 years), preschool/young children (age 5-9 years), preadolescents (age 10-14 years), and adolescents (age 15-17 years). Demographics, clinical injury data, patterns of spine injuries, associated injuries, treatment, and outcome were abstracted and analyzed. RESULTS: From a database of 897 severely (Injury Severity Score ≥ 16) injured pediatric patients, 28 children met the inclusion criteria. The mean age was 12.7 years (range, 1.3-16.7 years), and there were 18 males and 10 females. Younger children (age 0-9 years) sustained more injuries to the upper spine region, whereas injuries to the lumbar region were only seen in adolescents. Nine (32%) patients received surgical treatment for spine fracture or subluxation, and 15 (54%) were treated by nonoperative means. Four patients (14%) received only palliative treatment due to medical futility. Overall, the most commonly associated injury was thoracic injury (89%) followed by traumatic brain injury (64%). CONCLUSION: The age-related anatomy and physiology predispose younger children to upper spine injuries in contrast to lower spine injuries seen in adolescents. Predictors of mortality include pathologic pupillary light reflex, high Injury Severity Score and Abbreviated Injury Scale score, and a low Glasgow Coma Scale score at admission. Thoracic injuries were the most common associated injuries followed by traumatic brain injury. LEVEL OF EVIDENCE: Prognostic study, level III.

INTRODUCTION: Animal bite wounds are a significant problem, which have caused several preventable child deaths in clinical practice in the past. The majority of bite wounds is caused by dogs and cats, and also humans have to be considered to lead to those extreme complicated diagnosis in the paediatric patient population. Early estimation of infection risk, adequate antibiotic therapy and, if indicated, surgical treatment, are cornerstones of successful cures of bite wounds. However, antibiotic prophylaxis and wound management are discussed controversially in the current literature. In our study, we retrospectively investigated the bite source, infection risk and treatment options of paediatric bite wounds. METHODS: A total of 1592 paediatric trauma patients were analysed over a period of 19 years in this retrospective study at a level I trauma centre, Department of Trauma Surgery, Medical University of Vienna, Austria. Data for this study were obtained from our electronic patient records and follow-up visits. In our database, all paediatric patients triaged to our major urban trauma centre have been entered retrospectively. RESULTS: During the 19-year study period, 1592 paediatric trauma patients met the inclusion criteria. The mean age was 7.7 years (range 0-18.9), 878 (55.2%) were males and 714 (44.8%) were females. In our study population, a total of 698 dog bites (43.8%), 694 human bites (43.6%), 138 other bites (8.7%) and 62 cat bites (3.9%) have been observed. A total of 171 wounds (10.7%) have been infected. Surgical intervention was done in 27 wounds (1.7%). CONCLUSION: Gender-related incidence in bite wounds for dog and cat could be detected. Second, our findings for originator of bite wounds reflect the findings in the published literature. Total infection rate reached 10.7%, primary antibiotic therapy was administered in 221 cases (13.9%) and secondary antibiotic therapy in 20 (1.3%) cases. Observed infection rate of punctured wounds and wounds greater than 3 cm was 3 times higher than for all other wounds. Our findings need to be proven in further prospective clinical trials.

BACKGROUND: Cervical spine injuries are uncommon in pediatric trauma patients. Previous studies were often limited by the small numbers of patients available for evaluation. The aim of this study was to determine the incidence and characteristics of pediatric cervical spine injuries at this Level 1 trauma center and to review the authors' experiences with documented cases. METHODS: This study retrospectively analyzed the clinical records of all pediatric trauma patients with skeletal and/or nonskeletal injuries of the spine that were admitted to this Level 1 trauma center between 1980 and 2004. Those with significant injuries of the cervical spine were identified and included in this study. Pediatric patients were defined as patients younger than the age of 17 years. In addition, they were stratified by age into two study groups: group A included patients aged 8 years or fewer and group B contained patients from the ages of 9 to 16 years. RESULTS: We found 56 pediatric patients with injuries of the cervical spine that met criteria for inclusion. Thirty-one female and 25 male patients with an average age of 8.9 years (range, 1-16 years) sustained significant skeletal and/or nonskeletal injuries of the cervical spine and were entered in this study. Thirty patients (54%) were aged 8 years or fewer and entered into study group A, whereas 26 patients (46%) from the ages of 9 to 16 met criteria for inclusion in study group B. An analysis of data revealed that younger patients (group A) showed significantly more injuries of the upper cervical spine, whereas older children (group B) sustained significantly more injuries of the lower level. Spinal cord injuries without radiographic findings were only found in study group A. In addition, younger children were more likely injured by motor vehicle crashes, whereas older children more commonly sustained C-spine injuries during sports activities. Two-thirds of our patients showed neurologic deficits, and the overall mortality was 28%. CONCLUSION: The results of our study were similar to several previous reports, underscoring a low incidence (1.2%) and age-related characteristics. Younger children had a predilection for injuries of the upper cervical spine, whereas children in the older age group sustained significantly more injuries of the lower cervical spine. Spinal cord injuries without radiographic abnormalities were only seen in the younger age group. Despite the low incidence of cervical spine injuries in pediatric patients, increased efforts at prevention are demanded because mortality rate (27%) and incidence of neurologic deficits (66%) were dreadfully high in our series.

Clearing the cervical spine in polytrauma patients still presents a challenge to the trauma team. The risk of an overlooked cervical spine injury is substantial since these patients show painful and life-threatening injuries to one or more organ systems so that clinical examination is usually not reliable. A generally approved guideline to assess the cervical spine in polytrauma patients might significantly reduce delays in diagnosis, but a consistent protocol for evaluating the cervical spine has not been uniformly accepted or followed by clinicians. One purpose of this study was to analyse the common methods for cervical spine evaluation in critically injured patients and its safety and efficacy at this trauma centre. The second purpose was to present a comprehensive diagnostic C-spine protocol, based on the authors' experiences with documented cases. From a prospectively gathered polytrauma database, we retrospectively analysed the clinical records of all polytrauma patients, with skeletal and/or non-skeletal cervical spine injuries, who were admitted to this level I trauma centre between 1980 and 2004. All patients were assessed following the trauma algorithm of our unit (modified by Nast-Kolb). Standard radiological evaluation of the cervical spine consisted of either a single lateral view or a three-view cervical spine series (anteroposterior, lateral, odontoid). Further radiological examinations (functional flexion/extension views, oblique views, CT scan, MRI) were carried out for clinical suspicion of an injury or when indicated by the standard radiographs. Sixteen patients (14%) had a single cross-table lateral view for radiological assessment of the cervical spine during initial trauma evaluation, Twenty-nine patients had a three-view cervical spine series (anteroposterior, lateral, odontoid) and 81 patients underwent extended radiological examinations by cervical CT scan (n=52), functional flexion/extension views (n=26) or MRI (n=3). Correct diagnosis was made in 107 patients (91%) during primary trauma evaluation, whereas in 11 patients (9%) our approach to clear the cervical spine failed to detect significant cervical spine injuries. In six patients skeletal injuries were missed by a single lateral view and in two patients by a three-view standard series because inadequate radiographs with poor technical quality or incomplete visualization of the cervical spine did not show the extent of the injury. In three cases ligamentous injuries were missed despite complete sets of standard radiographs and cervical CT scan, but without functional radiography. Common methods for cervical spine evaluation in critically injured patients were plain radiographs, cervical CT scan and functional flexion/extension views. Cervical CT scan was the most efficient imaging tool in detecting skeletal injuries, showing a sensitivity of 100%. A single cross-table lateral view appeared to be insufficient, as we found a sensitivity of only 63%. Functional radiography or MRI was also necessary, as plain radiographs and CT scan failed to detect significant ligamentous injuries in 6% of the patients. For more comprehensive assessment of the C-spine, we presented a new C-spine protocol based on the authors' experiences, with the aim to avoid unnecessary delays in diagnosis.

BACKGROUND: Deep venous thrombosis (DVT) and pulmonary embolism (PE) may be significant complications following spinal surgery. The incidence rate ranges from 0.5% to 2.5% in patients with symptomatic thromboembolic disease and up to 15% in patients with non-symptomatic thrombotic complications. We determined the incidence of symptomatic thromboembolism after spinal surgery in patients with postoperative systemic prophylaxis and investigated general and specific risk factors for development of this disease. PATIENTS AND METHODS: We analyzed the clinical records of 978 patients who had undergone surgery of the spine because of trauma and who had been admitted to our level-I trauma center between 1980 and 2004. Spinal procedures included anterior and/or posterior spinal fusion, video-assisted thoracoscopic fusion, and spinal decompression. Symptomatic thromboembolic disease was diagnosed when patients showed significant clinical signs or symptoms of DVT or PE. In cases of DVT, diagnosis was confirmed by duplex scan of the lower limbs; in cases of PE, diagnosis was confirmed by CT-scanning of the thorax or at post mortem. RESULTS: The incidence rate of symptomatic thromboembolic complications was 2.2% (n 22). 17 patients showed clinical signs of deep venous thrombosis, with 4 of them developing pulmonary embolism subsequently. The other 5 patients developed pulmonary embolism without prior clinical signs of deep venous thrombosis. 6 patients died because of thromboembolic disease. Thromboembolic complications were more frequent in older patients and among males, as well as in patients with regular tobacco consumption and obesity. Thromboembolic complications were also seen more frequently in patients with surgical procedures at the lumbar spine, in patients with anterior spinal fusion, and in those with motor deficits in the lower extremities. INTERPRETATION: We found a rather low rate of clinically significant thromboembolic complications after spinal surgery because of trauma, compared to the results reported in the literature. Level of spinal surgery, surgical approach, and motor deficits in the lower extremities were identified as specific risk factors for DVT or PE. Age, sex, obesity and regular smoking were identified as general risk factors.

BACKGROUND: Correct diagnosis of cervical spine injuries is still a common problem in traumatology. The incidence of delayed diagnosis ranges from 5 to 20%. The aim of this study was to analyze the frequency and reasons for delayed or missed diagnosis at this Level I trauma unit and to provide recommendations for optimal examination of patients with suspected cervical spine injuries. METHODS: Analysis of clinical records showed 367 patients with cervical spine injuries who were admitted to this trauma department between 1980 and 2000. In all, 140 patients had an injury of the upper cervical spine (C1/C2), 212 patients had an injury of the lower cervical spine (C3-C7), and 15 patients had a combined injury of the upper and lower cervical spine. RESULTS: The diagnostic failure rate was 4.9% (n = 18). Results showed several profound reasons for missed or delayed diagnosis. In eight patients (44%), radiologic misinterpretation was responsible for delay in diagnosis; in five patients (28%), incomplete sets of radiographs were responsible. In four cases (22%), the injury was missed because inadequate radiographs did not show the level of the injury; in one case (6%), the treating surgeon did not see the radiographs. CONCLUSION: For optimal examination of patients with suspected cervical spine injuries, we recommend establishing specific diagnostic algorithms including complete sets of proper radiographs with functional flexion/extension views, secondary evaluation of the radiographs by experienced staff, and further radiologic examinations (computed tomography, magnetic resonance imaging) if evaluation of standard views is difficult.
