How to evaluate the quality of fracture reduction and fixation of the wrist and ankle in clinical practice: a Delphi consensus

MethodA Delphi study was conducted to obtain consensus on the most important criteria for the radiological evaluation of the reduction and fixation of the wrist and ankle. The Delphi study consisted of a bipartite online questionnaire, focusing on the interpretation of radiographs and CT scans of the wrist and the ankle. Questions addressed imaging techniques, aspects of the anatomy and fracture reduction and fixation. Agreement was expressed as the percentage of respondents with similar answers. Consensus was defined as an agreement of at least 90%.ResultsIn three Delphi rounds, respectively, 64, 74 and 62 specialists, consisting of radiologists, trauma and orthopaedic surgeons from the Netherlands responded. After three Delphi rounds, consensus was reached for three out of 14 (21%) imaging techniques proposed, 11 out of the 13 (85%) anatomical aspects and 13 of the 22 (59%) items for the fracture reduction and fixation. This Delphi consensus differs from existing scoring protocols in terms of the greater number of anatomical aspects and aspects of fracture fixation requiring evaluation and is more suitable in clinical practice due to a lower emphasis on measurements.

An X-ray template assessment for distal radial fractures

BackgroundThe current method for radiological measurements on plain X-rays of distal radius fractures is unreliable. We examined the reproducibility of a new X-ray assessment technique—where the uninjured side is used as a template for the injured side—compared to the conventional assessment technique.MethodsX-rays of 30 patients with a unilateral distal radial fracture were included reflecting the prevalence of AO fracture types in clinical practice. Eight experienced observers assessed these X-rays on two separated occasions (2-month interval) using the traditional measurement technique and the template technique. Reproducibility of the X-ray assessments was quantified by intraclass correlations and weighted kappa coefficients.ResultsThe reproducibility of the radial length measurement did not improve nor did the volar angulation measurement. However, marked improvement in reproducibility was observed for the radial inclination measurement, the kappa increased from 0.36 (95 % CI; 0.30–0.41) to 0.49 (95 % CI; 0.43–0.55) in the template technique. As a result, the classification of the reduction results (Lidström score) greatly improved. The overall kappa for the Lidström score improved from 0.37 (95 % CI; 0.31/0.43) to 0.59 (0.52/0.63).ConclusionThe assessment technique using the uninjured side as a template for the injured side resulted only in an improved reproducibility of the radial inclination measurement which in turn resulted in an improved classification reproducibility of the reduction results.

Indications for total-body computed tomography in blunt trauma patients: a systematic review

PurposeTotal-body CT scanning (TBCT) could improve the initial in-hospital evaluation of severe trauma patients. Indications for TBCT, however, differ between trauma centers, so more insight in how to select patients that could benefit from TBCT is required. The aim of this review was to give an overview of currently used indications for total-body CT in trauma patients and to describe mortality and Injury Severity Scores of patient groups selected for TBCT.MethodsA systematic review was performed by searching MEDLINE and Embase databases. Studies evaluating or describing criteria for selection of patients with potentially severe injuries for TBCT during initial trauma care were included. Also, studies comparing total-body CT during the initial assessment of injured patients with conventional imaging and selective CT in specific patient groups were included.ResultsThirty eligible studies were identified. Three studies evaluated indications for TBCT in trauma with divergent methods. Combinations of compromised vital parameters, severe trauma mechanisms and clinical suspicion on severe injuries are often used indications; however, clinical judgement is used as well. Studies describing TBCT indications selected patients in different ways and were difficult to compare regarding mortality and injury severity.ConclusionsIndications for TBCT in trauma show a wide variety in structure and cut-off values for vital parameters and trauma mechanism dimensions. Consensus on indications for TBCT in trauma is lacking.

Value of prehospital assessment of spine fracture by paramedics

BackgroundCurrent guidelines state that trauma patients at risk of spine injury should undergo prehospital spine immobilization to reduce the risk of neurological deterioration. Although this approach has been accepted and implemented as a standard for decades, there is little scientific evidence to support it. Furthermore, the potential dangers and sequelae of spine immobilization have been extensively reported. The role of the paramedic in this process has not yet been examined. The aim of this study was to evaluate the accuracy of prehospital evaluations for the presence of spine fractures made by paramedics.MethodsAll patients who presented with prehospital spine immobilization at our level II trauma center between January 2013 and January 2014 were prospectively included in a database. Prior to the diagnosis, paramedics recorded the probability of a spine fracture after a prehospital examination. These predictions were compared with patient outcomes. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated.ResultsOne hundred and thirty-nine patients were included that positive predictive value was 22%, negative predictive value was 95%, sensitivity was 92%, specificity was 30%, and accuracy was 41%.ConclusionsThe results of this study suggest that paramedics cannot accurately predict spinal fractures.

Non-operative treatment of displaced distal radius fractures leads to acceptable functional outcomes, however at the expense of 40% subsequent surgeries

BACKGROUND Although secondary displacement following closed reduction and plaster immobilisation is high, several guidelines still recommend non-operative treatment for displaced distal radius fractures with an adequate closed reduction. PURPOSE The purpose of this study was to evaluate functional outcomes, measured with the Disability of the Arm, Shoulder and Hand (DASH) questionnaire, in non-operative treated patients with displaced distal radius fractures and an adequate closed reduction confirmed on radiograph. MATERIALS AND METHODS From a retrospective database, we reviewed non-operative treated adult patients with an unilateral displaced distal radius fracture and adequate closed reduction confirmed on radiograph. The primary outcome was the DASH score at 12months. DASH scores were prospectively collected pre-trauma and at three, six and 12months. Secondary outcome was the number of subsequent surgeries due to secondary displacement or a symptomatic malunion, and their possible predictors. Additionally, the difference in DASH scores between patients who were treated due to secondary displacement and asymptomatic malunion was compared. RESULTS One-hundred and sixteen patients were included. The median age was 62 years and 79% was female. Fractures were classified according to the AO/OTA classification as follows: AO/OTA type A (49%), AO/OTA type B (3%), AO/OTA type C (48%). After 12months the median DASH score was 15. Forty-six (40%) patients underwent subsequent surgery due to a secondary displacement or symptomatic malunion. No significant differences in DASH scores between patients who were treated non-operatively and patients who received subsequent surgery were found. Younger patients were more likely to undergo subsequent surgery. Patients with a symptomatic malunion had significant higher DASH scores compared to patients with secondary displacement. DISCUSSION Non-operative treatment of displaced distal radius fractures after adequate closed reduction confirmed on radiograph leads to acceptable functional outcomes after 12months, however, at the expense of 40% subsequent surgeries. LEVEL OF EVIDENCE Level IV, retrospective cohort study.

Prehospital care of spinal injuries: a historical quest for reasoning and evidence

PurposeThe practice of prehospital immobilization is coming under increasing scrutiny. Unravelling the historical sequence of prehospital immobilization might shed more light on this matter and help resolve the situation. Main purpose of this review is to provide an overview of the development and reasoning behind the implementation of prehospital spine immobilization.MethodsAn extensive search throughout historical literature and recent evidence based studies was conducted.ResultsThe history of treating spinal injuries dates back to prehistoric times. Descriptions of prehospital spinal immobilization are more recent and span two distinct periods. First documentation of its use comes from the early 19th century, when prehospital trauma care was introduced on the battlefields of the Napoleonic wars. The advent of radiology gradually helped to clarify the underlying pathology. In recent decades, adoption of advanced trauma life support has elevated in-hospital trauma-care to an high standard. Practice of in-hospital spine immobilization in case of suspected injury has also been implemented as standard-care in prehospital setting. Evidence for and against prehospital immobilization is equally divided in recent evidence-based studies. In addition, recent studies have shown negative side-effects of immobilisation in penetrating injuries.ConclusionAlthough widely implementation of spinal immobilization to prevent spinal cord injury in both penetrating and blunt injury, it cannot be explained historically. Furthermore, there is no high-level scientific evidence to support or reject immobilisation in blunt injury. Since evidence in favour and against prehospital immobilization is equally divided, the present situation appears to have reached something of a deadlock.Graphical abstractThese slides can be retrieved under Electronic Supplementary Material.

Incidence of spinal fractures in the Netherlands 1997–2012

: To determine time trends of emergency department (ED) visits, hospitalization rates, spinal cord lesions and characteristics of patients with spinal fractures in the Netherlands. METHODS In an observational database study we used the Dutch Injury Surveillance System to analyse spinal fracture-related ED visits, hospitalization rates and spinal cord lesions between 1997 and 2012. RESULTS The total number of ED visits associated with spinal fractures increased from 4,507 in 1997 to 9,690 in 2012 (115% increase). The increase in the total number of fractures occurred in all age groups independently of gender. However, incidence rates increased more strongly with age and were higher in young males and ageing females. The hospitalization rate of diagnosed spinal fractures remained stable between 62 and 67%. The incidence of spinal cord lesions varied between 13.8 and 20.3 per million of the population over a period of 15 years. CONCLUSION Spinal fracture-related ED visits are increasing in the Dutch population, independently of age or gender. The hospitalization rate and the absolute numbers of spinal cord lesions have remained stable over a period of 15 years. These findings are relevant for public health decision-making and resource allocation.

Systematic CT evaluation of reduction and hardware positioning of surgically treated calcaneal fractures: a reliability analysis

IntroductionUp to date, there is a lack of reliable protocols that systematically evaluate the quality of reduction and hardware positioning of surgically treated calcaneal fractures. Based on international consensus, we previously introduced a 23-item scoring protocol evaluating the reduction and hardware positioning in these fractures based on postoperative computed tomography. The current study is a reliability analysis of the described scoring protocol.MethodsThree raters independently and systematically evaluated anonymized postoperative CT scans of 102 surgically treated calcaneal fractures. A selection of 25 patients was scored twice by all individual raters to calculate intra-rater reliability. The scoring protocol consisted of 23 items addressing quality of reduction and hardware positioning. Each of these four-option questions was answered as: ‘optimal’, ‘suboptimal (but not needing revision)’, ‘not acceptable (needing revision)’ or ‘not judgeable’. We used intraclass correlation coefficients (ICC’s) to calculate inter- and intra-rater reliability.ResultsInter-rater reliability of the overall 23-item protocol was good (ICC 0.66, 95% CI 0.64–0.69). Individual items that scored an inter-rater ICC ≥0.60 included evaluation of the calcaneocuboid joint, the posterior talocalcaneal joint, the anterior talocalcaneal joint, the position of the plate and sustentaculum screws and screws protruding the tuber and medial wall. The intra-rater reliability for the overall protocol was good for all three individual raters with ICC’s between 0.60 and 0.70.ConclusionOur scoring protocol for the radiological evaluation of operatively treated calcaneal fractures is reliable in terms of inter- and intra-rater reliability.
