Objectives: Intramedullary nailing has been accepted as the treatment of choice for femoral shaft fractures. The aim of our study was to determine the incidence and implications of rotational malalignment after intramedullary nailing using computed tomography measurements. Design: Cohort study. Setting: Patients who postoperatively visited the orthopaedic outpatient and radiology clinics. Patients: Seventy-six patients, 59 men and 17 women, with a mean age of 28.4 years (15–88). Intervention: Patients treated on a fracture table with an antegrade reamed AO nail (n = 46) or Grosse Kempf nail (n = 30) for a unilateral femoral shaft fracture between 1988 and 1998 were included in the study. Main Outcome Measurements: Patients filled out a questionnaire concerning pain, daily activities, and sport. Oxford, Western Ontario and McMaster University osteoarthritis index, and Harris Hip and Knee Society scores were obtained. Physical exams and computed tomography measurements were established. Results: Twenty-one patients (28%) were found to have a rotational malalignment of 15° or more. There was no significant difference in rotational deformity with either the AO or Grosse Kempf nail. The incidence of malrotation was independent of the fracture level. Patients with a torsional deformity had difficulties with more demanding activities like running, sports, and climbing stairs. Patients with an external rotational malalignment (n = 12) have more functional problems than patients with an internal rotational malalignment (n = 9). Clinically determined rotation differences are not accurate (±20°) compared with the established computed tomography measurements. Conclusions: Rotational malalignment after intramedullary nailing for femoral fractures is found in 28% of the patients in this study. These patients have difficulties with more demanding activities, especially when they have an external torsional deformity.

A study of 24 patients who sustained an extra-articular fracture of the distal third of the tibial shaft was performed to determine the effect of the type of treatment, open reduction and internal fixation (ORIF) or closed reduction and intramedullary (IM) nailing, on the occurrence of malalignment. All patients were treated in our clinic between 1993 and 2001 for a fracture in the distal third of the tibia. Twelve patients treated with ORIF were matched to 12 patients treated with IM nailing, with regard to gender, age decade, and the AO classification of the fracture. The group treated with IM nailing was assessed after a mean 6.0xa0years versus ORIF after a mean of 4.5xa0years. Two patients treated with ORIF versus six patients treated with IM nailing had a malalignment of the tibia. Furthermore, we found no difference with regard to time to union, non-union, hardware failure or deep infections between ORIF and IM nailing. Our results suggest that control of alignment is difficult with IM nailing of distal tibial fractures. For optimal alignment we advise considering the use of ORIF for closed and type I open extra-articular fractures in the distal third of the tibia.RésuméNous avons étudié 24 patients présentant une fracture extra articulaire du tiers distal de la diaphyse tibiale afin de déterminer quel était le meilleur type de traitement. Les patients ont été traités soit par réduction sanglante et fixation interne (ORIF) soit par réduction fermée et enclouage centromédullaire. Tous les patients ont été traités dans notre établissement entre 1993 et 2001. Douze patients traités par ostéosynthèse interne ont été comparés à 12 patients traités par enclouage centromédullaire, ces deux groupes étant comparables également en terme de sexe, d’âge, de classification AO. Le groupe traité par enclouage centromédullaire a été suivi pendant une moyenne de 6 ans alors que le groupe par ostéosynthèse, sur une moyenne de 4,5 ans. Deux patients traités par ostéosynthèse interne versus 6 patients traités par enclouage centromédullaire ont présenté un cal vicieux du tibia. Nous n’avons pas trouvé de différence significative sur le plan de la consolidation, du taux de pseudarthrose, du débricolage ou sur le taux d’infection. Nos résultats nous permettent de penser qu’il est plus difficile de traiter ce type de fracture avec l’enclouage centromédullaire et, nous conseillons, pour ce type de fractures fermées ou ouvertes de type I de faire un traitement pas ostéosynthèse interne.

BackgroundFatigue is one of the most frequently reported symptoms after Mild Traumatic Brain Injury (MTBI). To date, systematic and comparative studies on fatigue after MTBI are scarce, and knowledge on causal mechanisms is lacking.ObjectivesTo determine the severity of fatigue six months after MTBI and its relation to outcome. Furthermore, to test whether injury indices, such as Glasgow Coma Scale scores, are related to higher levels of fatigue.MethodsPostal questionnaires were sent to a consecutive group of patients with an MTBI and a minor-injury control group, aged 18–60, six months after injury. Fatigue severity was measured with the Checklist Individual Strength. Postconcussional symptoms and limitations in daily functioning were assessed using the Rivermead Post Concussion Questionnaire and the SF-36.ResultsA total of 299 out of 618 eligible (response rate 52%) MTBI patients and 287 out of 482 eligible (response rate 60%) minor-injury patients returned the questionnaire. Ninety-five MTBI patients (32%) and 35 control patients (12%) were severely fatigued. Severe fatigue was highly associated with the experience of other symptoms, limitations in physical and social functioning, and fatigue related problems like reduced activity. Of various trauma severity indices, nausea and headache experienced on the ED were significantly related to higher levels of fatigue at six months.ConclusionsIn conclusion, one third of a large sample of MTBI patients experiences severe fatigue six months after injury, and this experience is associated with limitations in daily functioning. Our finding that acute symptoms and mechanism of injury rather than injury severity indices appear to be related to higher levels of fatigue warrants further investigation.

Documenting the timing and organisation of trauma resuscitation can be utilised to assess performance standards, and to ensure a high quality of trauma resuscitation procedures. Since there is no European literature available on trauma resuscitation time (TRT) in the emergency room, the aim of this descriptive study is to evaluate TRT in the Netherlands. The introduction of an ATLS-trained prehospital mobile medical team (MMT) in the Nijmegen area initiated the on-site advanced trauma life-support for the prehospital management of trauma patients. We studied TRT in two groups of patients, one with, the other without on-site care by a MMT. In the emergency room the use of videotape recording was chosen to document trauma resuscitation (22 actions) and TRT. A specially flow-chart was used to define the TRT-procedures. We studied 43 patients; 27 without MMT treatment and 16 with MMT treatment. The activities were divided into the ABCDEs of trauma care. Significant more patients of the MMT group were intubated before arrival in the hospital (12/16 (75%) versus 2/27 (2%), P<0.05). Eleven definitive airway management interventions (intubation) and one thoracic drainage in the non-MMT group were demanded by the protocol, but not performed before arrival in the hospital. Sixteen out of 22 actions that were documented were carried out at an earlier stage in the MMT group. There was no significant difference between the resuscitation times; in both groups the recorded median time was approximately 43 min. This prospective analysis demonstrates the timing of resuscitation procedures in a resuscitation room and provides some insight into the timing of ATLS initial assessment.

This study aimed to evaluate the intra- and interobserver agreement for both fracture classification according to Schatzker and treatment plan of tibial plateau fractures using plain radiographs alone and with computed tomography (CT) scans. The study was carried out prospectively to assess the impact of an advanced radiographic study on the agreement of treatment plan and fracture classification of tibial plateau fractures. Eight experienced observers (six surgeons and two radiologists) classified 15 tibial plateau fractures with plain radiographs and CT scans and set up a treatment plan. Agreement was measured using kappa coefficients. Using plain radiographs alone, the mean interobserver kappa coefficient for classification was 0.47, which decreased to 0.46 after addition of CT scans. Using plain films alone for formulating a treatment plan, the mean interobserver kappa coefficient was 0.40, which decreased to 0.30 after addition of CT scans. The mean intraobserver kappa coefficient for fracture classification using plain radiographs was 0.60, which decreased to 0.57 with addition of CT scans. The mean intraobserver kappa coefficient for treatment plan based on plain radiographs alone was 0.53, which decreased to 0.45 after addition of CT scans. In contrast with other recent publications, there is no increase in inter- and intra-agreement of a CT scan compared to plain radiographs for the classification and treatment plan in tibial plateau fractures. Routine CT scanning of the knee for tibial plateau fractures is not supported by this study.

According to the Dutch medical education guidelines junior doctors are expected to be able to perform first aid and basic life support. A prospective study was undertaken to assess the level of first aid and basic life support (BLS) competence of junior doctors at the Radboud University Nijmegen Medical Centre (RUNMC), the Netherlands. Fifty-four junior doctors (18%), of the medical students in their final years, were submitted to a theoretical test, composed of multiple-choice questions concerning first aid and basic life support. This test was followed by a practical test consisting of two out-of-hospital first aid and basic life support scenarios including cardiopulmonary resuscitation (CPR). In total, 19% of the junior doctors passed the theoretical test. The first scenario was performed correctly in 11%. The CPR situation was correctly performed by 30% of the students as observed by the examiners but when assessed by the checklists of Berden only 6% of the students performed correct CPR. It is concluded that the level of first aid and basic life support of the junior doctors at the RUNMC is low and does not meet the required level as stated in the guidelines for practice of medical education in the Netherlands.

Purpose: Adequate education in first aid and basic life support (BLS) should be considered as an essential aspect of the medical curriculum. The objective of this study was to investigate the current medical training in first aid and BLS at all 8 medical schools in the Netherlands. Summary: An evaluation was made, by sending a questionnaire to all medical schools, regarding whether the medical training was performed in accordance with the national Dutch guidelines for medical education. The response was 100%. Seven of the eight medical schools train their students in first aid and BLS during the medical curriculum. An average of only 38% of the clinical pictures and diseases and 69% of the skills were mastered at the level-defined national Dutch guidelines. Conclusion: The medical education in the Netherlands does not meet the required objectives as stated in the national Dutch guidelines concerning first aid and BLS.Purpose: Adequate education in first aid and basic life support (BLS) should be considered as an essential aspect of the medical curriculum.

ObjectiveShock is defined as a change of circulation which results in hypoxia at the tissue level. Lactate and base deficit (BD) are associated with a high risk of multiple organ dysfunction in trauma patients. In this study we evaluated the influence of early recognition of shock in trauma patients.MethodsIn a retrospective study, relevant data were collected from the Radboud University Nijmegen Medical Centre (RUNMC) database between January 2009 and December 2010. Vital parameters were taken at the accident scene, and patients were divided into four shock classes. Arterial blood gas analysis was performed on arrival in the emergency department. Statistical analysis was performed with SPSS version 17.0. Statistical significance was assumed at pxa0≤xa00.05.ResultsA total of 255 patients were included. Patients who suffered from prehospital shock, and those who were intubated prior to hospital admittance showed a bad outcome, presenting with a more severe metabolic acidosis, higher ISS and higher mortality. There was a significant difference for bicarbonate and BD between shockclass Ixa0+xa0II and shockclass IIIxa0+xa0IV, respectively 22.7 vs. 19.7 and −3.4 vs. −6.9. Intubated patients had a decreased bicarbonate and BD compared to not intubated patients, respectively 21.81 vs. 23.24 and −5.08 vs. −2.38. Mortality and ISS were higher in patients in shock class III and IV. Significant differences in serum lactate levels were not found.ConclusionsPrehospital shock influences patient outcome; outcome of patients is related to initial shock classification. Further validation of our shock classification, however, is necessary.

We report a lethal case of fat embolism syndrome in a nine-year-old child after a direct blunt trauma leading to a pelvic fracture. On the second day, signs of bowel perforation and septic shock led to an acute aggravation of the pulmonary symptoms, cardiac arrest and death. Fat embolism is seldom thought to occur in pediatric trauma patients; however, this case illustrates it can lead to disastrous sequela. Since there is no specific treatment for it, prevention by early fracture stabilization is the only option.
