How to evaluate the quality of fracture reduction and fixation of the wrist and ankle in clinical practice: a Delphi consensus
Complex regional pain syndrome - phenotypic characteristics and potential biomarkers
Complex regional pain syndrome (CRPS) is a pain condition that usually affects a single limb, often following an injury. The underlying pathophysiology seems to be complex and probably varies between patients. Clinical diagnosis is based on internationally agreed-upon criteria, which consider the reported symptoms, presence of signs and exclusion of alternative causes. Research into CRPS biomarkers to support patient stratification and improve diagnostic certainty is an important scientific focus, and recent progress in this area provides an opportunity for an up-to-date topical review of measurable disease-predictive, diagnostic and prognostic parameters. Clinical and biochemical attributes of CRPS that may aid diagnosis and determination of appropriate treatment are delineated. Findings that predict the development of CRPS and support the diagnosis include trauma-related factors, neurocognitive peculiarities, psychological markers, and local and systemic changes that indicate activation of the immune system. Analysis of signatures of non-coding microRNAs that could predict the treatment response represents a new line of research. Results from the past 5 years of CRPS research indicate that a single marker for CRPS will probably never be found; however, a range of biomarkers might assist in clinical diagnosis and guide prognosis and treatment
Accuracy and consequences of 3D-fluoroscopy in upper and lower extremity fracture treatment: A systematic review
Objectives: The aim of this systematic review was to compare the diagnostic accuracy, subjective image quality and clinical consequences of 3D-fluoroscopy with standard imaging modalities (2D-fluoroscopy, X-ray or CT) during reduction and fixation of intra-articular upper and lower extremity fractures. Methods: A systematic literature search was performed in MEDLINE, EMBASE and the Cochrane library. In total 673 articles were identified (up to March 2012). The 19 included studies described patients/cadavers with intra-articular upper/lower extremity fractures and compared 3D-fluoroscopy to standard imaging. The study was performed in accordance with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) guidelines. Diagnostic accuracy was defined by the quality of fracture reduction or implant position and, if possible, expressed as sensitivity and specificity; subjective image quality was determined by the quality of depiction of bone or implants; clinical consequences were defined as corrections in reduction or implant position following 3D-fluoroscopy. Results: Ten cadaver-and nine clinical studies were included. A meta-analysis was not possible, because studies used different scoring protocols to express diagnostic accuracy and reported incomplete data. Based on the individual studies, diagnostic accuracy of 3D-fluoroscopy was better than 2D-fluoroscopy and X-ray, but similar to CT-scanning. Subjective image quality of 3D-fluoroscopy was inferior compared to all other imaging modalities. In 11-40% of the operations additional corrections were performed after 3D-fluoroscopy, while the necessity for these corrections were not recognized based on 2D-fluoroscopic images. Conclusions: Although subjective image quality is rated inferior compared to other imaging modalities, intra-operative use of 3D-fluoroscopy is a helpful diagnostic tool for improving the quality of reduction and implant position in intra-articular fractures.

Epidemiology of extremity fractures in the Netherlands
Insight in epidemiologic data of extremity fractures is relevant to identify people at risk. By analyzing age- and gender specific fracture incidence and treatment patterns we may adjust future policy, take preventive measures and optimize health care management. Current epidemiologic data on extremity fractures and their treatment are scarce, outdated or aiming at a small spectrum of fractures. The aim of this study was to assess trends in incidence and treatment of extremity fractures between 2004 and 2012 in relation to gender and age. We used a combination of national registries of patients aged ≥ 16 years with extremity fractures. Fractures were coded by the International Classification of Diseases (ICD) 10, and allocated to an anatomic region. ICD-10 codes were used for combining the data of the registries. Absolute numbers, incidences, number of patients treated in university hospitals and surgically treated patients were reported. A binary logistic regression was used to calculate trends during the study period. From 2004 to 2012 the Dutch population aged ≥16 years grew from 13,047,018 to 13,639,412 inhabitants, particularly in the higher age groups of 46 years and older. The absolute number of extremity fractures increased significantly from 129,188 to 176,129 (OR 1.308 [1.299-1.318]), except for forearm and lower leg fractures. Incidences increased significantly (3-4%) for wrist, hand/finger, hip/upper leg, ankle and foot/toe fractures. In contrast to the older age categories from 66 years and older, in younger age categories from 16 to 35 years, fractures of the extremities were more frequent in men than in women. Treatments gradually moved towards non-university hospitals for all except forearm fractures. Both relative and absolute numbers increased for surgical treatments of clavicle/shoulder, forearm, wrist and hand/finger fractures. Contrarily, lower extremity fractures showed an increase in non-surgical treatment, except for lower leg fractures. During the study period, we observed an increasing incidence of extremity fractures and a shift towards surgical treatment. Patient numbers in university hospitals declined. If these trends continue, policy makers would be well advised to consider the changing demands in extremity fracture treatment and pro-actively increase capacity and resource
Systematic CT evaluation of reduction and hardware positioning of surgically treated calcaneal fractures: a reliability analysis
Up 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. Three 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. Inter-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 ae 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. Our scoring protocol for the radiological evaluation of operatively treated calcaneal fractures is reliable in terms of inter- and intra-rater reliabilit
Wound infections following open reduction and internal fixation of calcaneal fractures with an extended lateral approach
Post-operative wound infections (PWI) following calcaneal fracture surgery can lead to prolonged hospital stay and additional treatment with antibiotics, surgical debridement or implant removal. Our aim was to determine the incidence of superficial and deep PWI and to identify risk factors (RF). This study is a retrospective case series. All consecutive patients from 2000 to 2010 with a closed unilateral calcaneal fracture treated with open reduction and internal fixation (ORIF) by an extended lateral approach were included. Patient, fracture, trauma and peri-operative characteristics were collected, including RF such as smoking, diabetes mellitus, time to operation, pre-operative in- or outpatient management and wound closure technique. The primary end point was a PWI as defined by the US Centers for Disease Control and Prevention. A total of 191 patients were included of which 47 patients (24.6%) had a PWI; 21 (11.0%) and 26 (13.6%) patients had a superficial and deep wound infection, respectively. American Society of Anesthesiologists (ASA) classification higher than ASA 1 was associated with an increased risk. Placement of a closed suction drain at the end of surgery was associated with less PWI (35% vs 15%, p = 0.002). In this study, none of the previously reported RF were associated with an increased risk for PWI. ORIF of displaced calcaneal fractures is associated with a high rate of PWI of 25%. Factors that were associated with an increased risk were ASA classification other than 1 and absence of a closed suction drain placement. A closed suction drain may be a protective measure to avoid wound complication

The Value of Intraoperative 3-Dimensional Fluoroscopy in the Treatment of Distal Radius Fractures: A Randomized Clinical Trial
Purpose: This study attempted to determine the clinical effectiveness of the intraoperative use of 3-dimensional fluoroscopy compared with conventional 2-dimensional fluoroscopy in patients with distal radius fractures. Methods: We performed a multicenter randomized clinical trial in which 206 patients were randomized between the use of 3-dimensional fluoroscopy or not during operative treatment of the distal radius fracture. The primary outcome was the quality of fracture reduction and fixation assessed on a postoperative computed tomography scan with a dichotomous outcome: indication for revision, yes or no. Results: There was no significant difference in whether the fracture required revision surgery: 31% (2-dimensional group) versus 24% (3-dimensional group). In 11% of distal radius fractures allocated to the 3-dimensional group, additional intraoperative corrections (screw replacements) were performed. Conclusions: Compared with 2-dimensional fluoroscopy, the use of intraoperative 3-dimensional fluoroscopy does not appear to improve the quality of reduction and fixation in the management of patients with a distal radius fracture. However, the use of 3-dimensional fluoroscopy appears to have advantages such as more intraoperative revisions and less revision surgeries that this study could not clearly demonstrate.
