Treatment of displaced intra-articular calcaneal fractures: A single-center experience study with 20 years follow-up.

INTRODUCTION: This study was conducted to identify the patient characteristics, classification, treatment, complications, and functional outcomes of operatively treated displaced intra-articular calcaneal fractures (DIACFs) in a level-I trauma center over a 20-year period. METHODS: Patients with a DIACF classified as Sanders ≥2 and operatively treated with percutaneous reduction and screw fixation (PSF) or open reduction and internal fixation (ORIF) between 1998 and 2017 were identified. Pre- and postoperative radiological assessments were performed. Functional outcomes were evaluated using the American Orthopaedic Foot & Ankle Society (AOFAS) score and the Maryland Foot Score (MFS). General health and patient satisfaction were assessed using the Short Form-36 Health Survey (SF-36) and the visual analog scale (VAS). RESULTS: In total, 120 patients with a DIACF that were operatively treated with PSF or ORIF. Of these patients, 72 with a total of 80 DIACFs completed the questionnaires (60%). The average follow-up was 130 months. Mean scores for PSF and ORIF were 74 and 75 for AOFAS, 78 and 78 for MFS, 68 and 61 for SF-36, and 7.7 and 7.5 for VAS, respectively. An infection was the most common complication associated with ORIF (31%), and hardware removal (58%) was the most common complication in patients treated with PSF. Overall, 36 patients (68%) were able to return to work after a median time 6 months (IQR, 3-7) and 6 months (IQR, 3,25-6,75) for PSF and ORIF treated, respectively CONCLUSION: This long-term follow-up study reviews ORIF using ELA and PSF in the treatment of DIACFs. This study shows that both treatments are capable of restoring the Böhler angle and yield relatively good long-term functional outcomes. Differences in complication rates were apparent, infectious problems are inherent to ORIF using ELA, and hardware removal is associated with PSF.

Long-term results of displaced intra-articular calcaneal fractures treated with minimal invasive surgery using percutaneous screw fixation.

INTRODUCTION: Over the last 20 years, minimally invasive surgery using Percutaneous Screw Fixation (PSF) has been performed increasingly frequently in the treatment of Displaced Intra-Articular Calcaneal Fractures (DIACFs). The purposes of this study were to assess the long-term postoperative outcomes of mobility, foot function, stability, pain and patient satisfaction. METHODS: All patients had DIACFs and underwent PSF between 1998 and 2006 according to the method reported by Forgon and Zadravecz. Functional outcomes, range of motion and change in footwear were evaluated with the American Orthopaedic Foot & Ankle Society (AOFAS) score and the Maryland Foot Score (MFS). All patients completed a general health status form (Short Form-36 [SF-36]) and visual analogue scale (VAS) for patient satisfaction. Anatomical restoration was assessed based on the pre- and postoperative radiographic images. RESULTS: Sixty-six patients with an DIACF were observed in the period 1998-2006. Patients who had open fractures, died or were <18 years of age at trauma were excluded. A total of 46 patients were asked to complete the questionnaires, during the last quarter of 2018. Of these patients, 27 with 29 DIACFs responded (58%). Nineteen were males, and the mean age at trauma was 45 years. Seven cases were classified as Sanders type II, 14 as Sanders type III, and 8 as Sanders type IV. The mean pre- and postoperative Böhler angles were 10 ͦ and 26 ͦ, respectively. The average follow-up period was 16 years, and at the follow-up, the mean AOFAS, MFS, SF-36 and VAS scores were 76, 74, 63 and 7.7 points, respectively. In comparison to the results at 5-10 years postoperatively in a previous study, we observed a decline in the average AOFAS and MFS scores by 8 and 11 points, respectively. Patient satisfaction decreased by 0.1 points and general health by 14 points. CONCLUSION: The long-term results of this study show relatively good functional outcomes is two-thirds of the treated patients. According to the reported scores, patients described their level of function as essentially normal. PSF should therefore be considered as a good option in patients with DIAC fractures, especially in patients with Sanders II and III fractures. LEVEL OF EVIDENCE: Therapeutic Level III.

Quality of life after pelvic ring fractures: Long-term outcomes. A multicentre study.

AIMS: This study was conducted to determine long-term (5-10 years) health-related quality of life (HRQOL) and ceiling effects in patients with a pelvic ring fracture. PATIENTS AND METHODS: We identified all patients with pelvic ring fractures after high-energy trauma admitted at two level 1 trauma centres in the Netherlands from 2006 to 2011. Patients were asked to complete the Majeed Pelvic Score (MPS), EuroQol-5D (EQ-5D) and Short Musculoskeletal Function Assessment (SMFA) questionnaires. HRQOL analysis used a multiple linear regression model. RESULTS: In total, 136 patients returned the questionnaires. The median follow-up period was 8.7 years. The mean MPS and EQ-5D-VAS scores were 85.1 and 74, respectively. The mean EQ-5D index scores were 0.87, 0.81 and 0.82 in Tile B, A and C patients, respectively. The mean SMFA index was 24. A ceiling effect was observed for 1/3 of the patients. After multiple linear regression analysis, no differences were identified among the various fracture types for each questionnaire, with the exception of 2 subscales of the MPS. CONCLUSION: Patients who suffer pelvic ring fractures generally have good HRQOL outcomes after 5-10 years. No significant differences were found among different fracture types. Long-term follow-up of patients with Tile C fractures is warranted.

Patient-reported outcome measures after surgery for an acetabular fracture.

Aims: The aim of this study was to record the incidence of post-traumatic osteoarthritis (OA), the need for total hip arthroplasty (THA), and patient-reported outcome measures (PROMS) after surgery for a fracture of the acetabulum, in our centre. Patients and Methods: All patients who underwent surgery for an acetabular fracture between 2004 and 2014 were included. Patients completed the 36-Item Short Form Health Survey (SF-36) and the modified Harris Hip Score (mHHS) questionnaires. A retrospective chart and radiographic review was performed on all patients. CT scans were used to assess the classification of the fracture and the quality of reduction. Results: A total of 220 patients were included, of which 55 (25%) developed post-traumatic OA and 33 (15%) underwent THA. A total of 164 patients completed both questionnaires. At a mean follow-up of six years (2 to 10), the mean SF-36 score for patients with a preserved hip joint was higher on role limitations due to physical health problems than for those with OA or those who underwent THA. In the dimension of bodily pain, patients with OA had a significantly better score than those who underwent THA. Patients with a preserved hip joint had a significantly better score on the function scale of the mHHS and a better total score than those with OA or who underwent THA. Conclusion: Of the patients who were treated surgically for an acetabular fracture (with a mean follow-up of six years), 15% underwent THA at a mean of 2.75 years postoperatively. Patients with a THA had a worse functional outcome than those who retain their native hip joint. We recommend using PROMS and CT scans when reviewing these patients.

Open pelvic fracture: the killing fracture?

BACKGROUND: Open pelvic fractures are rare but represent a serious clinical problem with high mortality rates. The purpose of this study was to evaluate the outcomes of open pelvic fractures in our clinic and to compare the results from our patient group with those of closed fractures and with the literature from the past decade. METHODS: Data of patients older than 16 years of age who were admitted to our hospital with a pelvic fracture between January 1, 2004, and December 31, 2014, were analyzed. The collected data were patient demographics, mechanism of injury, RTS, ISS, transfusion requirement during the first 24 h, Gustilo-Anderson and Faringer classification, number and type of interventions complications, mortality, and length of stay. RESULTS: Twenty-four of 492 patients (5% of all pelvic fracture patients) had an open fracture. Their mean age was 36 years, the mean ISS was 31, and the mean number of transfused packed red blood cells was 5.5. These numbers were all significantly higher than in the patients with a closed fracture, although they were comparable to other studies with open fractures. The mortality was 4% in the open group versus 14% in the closed group (p = 0.23). The reported mortality in the literature ranges between 4 and 45%. CONCLUSION: Open pelvic fractures are relatively rare but are a cause of significant morbidity. In this series, we treated patients with open pelvic fractures successfully, with a survival rate of 96%. There was no significant difference in survival rate between open and closed pelvic fractures. Compared with other studies, the mortality in our study was relatively low.

Paediatric pelvic fractures: how do they differ from adults?

BACKGROUND: The aim of this article was to review the incidence, presentation, treatment and complications of paediatric pelvic fractures of children who were admitted to our level 1 trauma centre and to compare them with our data from adult pelvic fracture patients. METHODS: We conducted a retrospective chart review of all children with pelvic fractures who were managed at our institution between January 1993 and December 2013 and compared the data with our database on pelvic fractures in adults during the period 2007 to 2012. RESULTS: We identified 51 children and 268 adults with pelvic fractures. The median age of the paediatric patients was 11 years. Children were significantly more involved in traffic accidents than adults (p < 0.001). Adults had a significantly higher Injury Severity Score (ISS) (31 vs 24.5; p < 0.03) and were significantly more often haemodynamically unstable (p < 0.01). Adults had a type C fracture more often, while children had a type B fracture (p < 0.001). Associated injuries were seen in both groups; however, thoracic injuries were significantly higher in adults (p < 0.01) and injuries to the extremities were higher in children (p < 0.01). Adults were significantly more often treated with open reduction and internal fixation (p < 0.001). Mortality in both groups, however, did not differ (6% vs 8%). CONCLUSION: Paediatric pelvic fractures are rare. They differ from adult pelvic fractures in presentation, associated injuries and management. Mortality, however, is substantial and does not differ from the adult population. Mortality is often due to concomitant injuries and not to exsanguination from the pelvic fracture.

Polytrauma at the Emergency Department; can we relate arterial blood gas analysis to a shock classification?

OBJECTIVE: Shock 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. METHODS: In 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 p ≤ 0.05. RESULTS: A 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 I + II and shockclass III + IV, 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. CONCLUSIONS: Prehospital shock influences patient outcome; outcome of patients is related to initial shock classification. Further validation of our shock classification, however, is necessary.

Treatment of displaced intra-articular calcaneal fractures with closed reduction and percutaneous screw fixation.

BACKGROUND: Surgical treatment of displaced intra-articular fractures of the calcaneus is a standard procedure in many institutions. To avoid soft-tissue complications, several minimally invasive procedures have recently been introduced. The aim of this study was to assess the percutaneous treatment of displaced intra-articular calcaneal fractures with use of one of these techniques. METHODS: All patients who underwent percutaneous screw fixation according to the method of Forgon and Zadravecz between 1998 and 2006 were selected. Postoperative infections were recorded. During follow-up, pain, functional outcome, range of motion, and change in footwear were evaluated with the use of the American Orthopaedic Foot & Ankle Society (AOFAS) score and the Maryland Foot Score (MFS). All patients also completed a general health status form (Short Form-36 [SF-36]) and a visual analog scale (VAS) for patient satisfaction. Subsequent subtalar arthrodesis and the removal of irritating screws were performed when indicated. RESULTS: We reviewed the cases of thirty-seven patients who had a combined total of thirty-nine displaced intra-articular calcaneal fractures and a follow-up period of at least twenty-four months. Five wound infections occurred, two of which were superficial and three of which were deep. At a mean follow-up time of sixty-six months, the mean AOFAS and MFS scores were 84 and 86 points, respectively, of 100 possible points. The mean score on the SF-36 was 76 points, and the mean score on the visual analog scale for patient satisfaction was 7.9 points of 10 possible points. Twenty-nine patients (78%) were able to wear normal shoes. At the time of follow-up, subtalar arthrodesis had been performed in two patients and seventeen patients (46%) had undergone an uncomplicated removal of painful screws. No substantial correlation was found between the severity of the fracture (Sanders classification) or the quality of the reduction when correlated with functional outcome parameters. CONCLUSIONS: We consider the technique of Forgon and Zadravecz to be an excellent option for the treatment of displaced intra-articular calcaneal fractures in selected patients despite the frequent need for screw removal following fracture-healing.

First aid and basic life support: a questionnaire survey of medical schools 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.

[Intraoperative parathyroid hormone measurement in patients with primary hyperparathyroidism; particularly valuable for suspected solitary parathyroid adenoma and re-operation]. / Intraoperatieve bepaling van parathormoon bij primaire hyperparathyreoïdie; vooral waardevol bij vermoeden van solitair bijschildklieradenoom en bij heroperatie.

OBJECTIVE: Analysis of the value of intraoperative parathormone (PTH) measurement in patients with primary hyperparathyroidism. DESIGN: Prospective study. METHOD: Evaluation of the value of intraoperative measurement ofPTH in 75 patients (including 19 patients with multiple endocrine neoplasia(MEN)-1 syndrome) who underwent parathyroidectomy in 2001-2005. RESULTS: The so-called Miami-criterion (PTH concentration 10 min after excision at least 50% below the value measured prior to the first incision) correctly predicted the success of the operation in 91% of the subjects. The success rate was correctly predicted as follows: in subgroups of patients with MEN-1 syndrome, 85%, patients after exclusion of MEN-1, 94%, and patients in whom a solitary adenoma was likely after preoperative localization studies, 97%. In 13% of the total number of operations, PTH-measurements led to further exploration, removal of additional parathyroid tissue and normocalcemia postoperatively. In patients without MEN-1 syndrome, in whom a solitary adenoma was likely on the basis of preoperative investigations, it was possible to limit the operation to a unilateral procedure in 87%. CONCLUSION: In the majority of patients with primary hyperparathyroidism, intraoperative PTH-measurement in combination with preoperative imaging studies leads to patients being cured with a unilateral instead of a bilateral operation.

Safety of computer-assisted surgery for cannulated hip screws.

Computer-assisted orthopaedic surgery has developed considerably during the past few years. Several manufacturers produce hardware and software for use in trauma surgery. Validation of these systems before clinical application is mandatory to be sure they work accurately and safely. The accuracy of surgical performance is highly correlated with the cut-out percentages of hip screws. In a standardized operative setting, three cannulated hip screws were inserted in each of 20 sawbones. The screws were positioned either by fluoroscopic navigation technique or by conventional operative technique depending on randomization. Our primary aim was to assess whether computer-navigated screw fixation is equally safe compared with conventional screw fixation using fluoroscopy. To determine safety, we investigated number of drilling attempts, screw position, and radiation time. Secondary to these safety parameters, we also compared the operating time between the two procedures to assess the efficiency of computer navigation. Statistical analysis showed no differences regarding accuracy of screw position. Computer-assisted surgery resulted in fewer drilling attempts and less radiation time, with a similar operation time. We believe the currently used navigation system is safe and accurate.

[The level of first aid and basic life support for the next generation of physicians]. / Het niveau van eerstehulpverlening en basale reanimatie door aankomende artsen.

According to Dutch medical-education guidelines junior doctors are expected to be able to carry out first aid and basic life support. We determined the level of first aid and basic life support of junior doctors at the Radboud University Nijmegen Medical Centre, The Netherlands. Of the 300 junior doctors 54 (18%) were submitted to a theoretical test, consisting of 52 multiple-choice questions on first aid and basic life support. This was followed by a practical test consisting of two first aid and basic life support scenarios including cardiopulmonary resuscitation (CPR). The scenarios were evaluated by certified examiners who used Berden's internationally accepted criteria. 19% of the junior doctors passed the theoretical test. The first-aid scenario was performed correctly in 11% of the cases. According to the examiners the CPR situation was performed correctly by 30% of the junior doctors but when assessed by Berden's international criteria only 6% of the junior doctors had performed CPR correctly. The level of first aid and basic life support amongst junior doctors was low and so the majority of them did not meet the required level as stated in the guidelines for practice of medical education in The Netherlands on this subject.

Rotational malalignment after intramedullary nailing of femoral fractures.

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 15degrees 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 (+/-20degrees) 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.

Glial and neuronal proteins in serum predict outcome after severe traumatic brain injury.

OBJECTIVE: To study the ability of glial (glial fibrillary acidic protein [GFAP] and S100b) and neuronal (neuron specific enolase [NSE]) protein levels in peripheral blood to predict outcome after severe traumatic brain injury. METHODS: Eighty-five patients with severe traumatic brain injury (admission Glasgow Coma Score [GCS] < or = 8) were included. Blood samples taken at the time of hospital admission were analyzed for S100b, GFAP, and NSE. Data collected included demographic and clinical variables. Outcome was assessed using the Glasgow Outcome Scale (GOS) at 6 months post injury. RESULTS: The median serum levels of S100b, GFAP, and NSE were raised 18.3 fold (S100b), 4.6 fold (GFAP), and twofold (NSE) compared to normal reference values. S100b, GFAP, and NSE serum levels correlated significantly with the injury severity score and CT findings but not with age, sex, or GCS. S100b, GFAP, and NSE levels were significantly higher in patients who died or had a poor outcome 6 months post injury than in those who were alive or had good outcome. S100b level >1.13 microg/L was the strongest predictor of death with 100% discrimination, but GFAP (>1.5 microg/L) and NSE (>21.7 microg/L) levels also strongly predicted death (adjusted odds ratios 5.82 [for GFAP] and 3.91 [for NSE]). S100b, GFAP, and NSE all strongly predicted poor outcome (adjusted odds ratios 5.12 [S100b], 8.82 [GFAP], and 3.95 [NSE]). CONCLUSIONS: These results suggest that determination of serum levels of glial and neuronal proteins may add to the clinical assessment of the primary damage and prediction of outcome after severe traumatic brain injury.

Two cases of subcutaneous Scedosporium apiospermum infection treated with voriconazole.

Scedosporium apiospermum is a mold that is increasingly being recognized as an opportunistic pathogen in immunocompromised patients, and treatment is complicated by intrinsic resistance to several antifungal agents. In our hospital, two cases of S. apiospermum infection occurring within 2 weeks were successfully treated with voriconazole. Since both patients were infected with an uncommon pathogen, a search for a common nosocomial source was performed. As environmental cultures yielded no S. apiospermum, and random amplified polymorphic DNA (RAPD) fingerprinting showed that the patients' strains were genotypically unrelated, we considered a common nosocomial source of S. apiospermum to be unlikely.
