ABSTRACT
PURPOSE: Despite the availability of clinical guidelines for hip fracture patients, adherence to these guidelines is challenging, potentially resulting in suboptimal patient care. The goal of this study was (1) to evaluate and benchmark the adherence to recently established quality indicators (QIs), and (2) to study clinical outcomes, in fragile hip fracture patients from different European countries. METHODS: This observational, cross-sectional multicenter study was performed in 10 hospitals from 9 European countries including data of 298 consecutive patients. RESULTS: A large variation both within and between hospitals were seen regarding adherence to the individual QIs. QIs with the lowest overall adherence rates were the administration of systemic steroids (5.4%) and tranexamic acid (20.1%). Indicators with the highest adherence rates (above 95%) were pre-operative (99.3%) and post-operative haemoglobin level assessment (100%). The overall median time to surgery was 22.6 h (range 15.7-42.5 h). The median LOS was 9.0 days (range 5.0-19.0 days). The most common complications were delirium (23.2%) and postsurgical constipation (25.2%). CONCLUSION: The present study shows large variation in the care for fragile patients with hip fractures indicating room for improvement. Therefore, hospitals should invest in benchmarking and knowledge-sharing. Large quality improvement initiatives with longitudinal follow up of both process and outcome indicators should be initiated.
ABSTRACT
INTRODUCTION: People with an intellectual disability (ID) are at risk of developing challenging behavior. Although previous research provided important insights into how to support people with an ID and challenging behavior, it remains unclear what various stakeholders consider to be the most essential aspects to further improve their support. METHOD: Statements regarding aspects perceived necessary to improve the support to people with an ID and challenging behavior were collected in focus groups. Afterwards participants individually prioritized and clustered these statements, resulting in concept maps for people with an ID, direct support workers, and psychologists. Since only three relatives participated in the entire concept mapping procedure, no concept map could be composed based on their input. RESULTS: Participants generated 200 statements. In the concept map of clients, statements were mentioned regarding relational aspects, providing clarity and structure, characteristics of support staff, and professional attitude of direct support workers. Direct support workers provided statements related to their own personal competencies, the necessity of feeling supported and appreciated, and a physical safe environment. Psychologists provided statements regarding their support for direct support workers, the support for the clients, the perspective on the client, and their role as psychologists. CONCLUSION: The results of this study may be a starting point to foster increased evidence based practice for the support for persons with an ID and challenging behavior. Moreover, it provides opportunities to create care founded on mutual attunement, based on listening to each other's ideas and insight into perspectives and needs of various stakeholders.
ABSTRACT
BACKGROUND: Beneficial effects of pulmonary rehabilitation at high-altitude (HAPR) in patients with severe refractory asthma have been reported earlier, but evidence for the effectiveness is limited. AIM: To investigate the effectiveness of high-altitude pulmonary rehabilitation to comparable treatment at sea-level (LAPR) on patient outcome parameters. METHODS: Adults with severe refractory asthma living in The Netherlands were included. Treatment consisted of a 12-week personalized multidisciplinary rehabilitation program either at high-altitude (Davos Switzerland) (n = 93) or in a tertiary lung center at sea-level in The Netherlands (n = 45). At baseline, after treatment, and during 12 months follow-up asthma related quality of life (AQLQ), asthma control (ACQ), pulmonary function and OCS-dose were assessed. Patients could not be randomized resulting in different asthma populations. Groups were compared using linear regression analysis (ANCOVA) adjusted for baseline values, in addition to age, atopy, smoking history, BMI and gender. RESULTS: After treatment, and at 12 months follow-up, improved AQLQ(0.92,p < 0.001 and 0.82,p = 0.001, respectively), ACQ(-0.87,p < 0.001 and -0.69,p = 0.008, respectively) and lower maintenance OCS dose (Unadjusted linear regression analysis-5.29 mg, p = 0.003 and Crude Odds Ratio-1.67, p = 0.003, respectively) were observed in the HAPR-group compared to the LAPR group. Patients receiving HAPR also had less asthma exacerbations (≥1 exacerbation: 20% vs 60%,p < 0.001) and showed improvement in lung function (%predFEV1 3.4%,p = 0.014) compared to the LAPR group, but at 12 months no differences between groups were observed. CONCLUSION: HAPR resulted in a larger improvement in patient outcome parameters compared to LAPR, on the long run the improvement in patient reported symptoms and lower maintenance OCS-dose persists. Underlying factors that explain this observed effect need to be investigated.

BACKGROUND: Indication for surgical treatment of posterior tibial plateau fractures (TPFs) remains up for debate. Three-dimensional computed tomography (3D-CT) reconstruction can provide insight into fracture morphology and could improve treatment strategy and surgical planning. In this study, we investigated the value of 3D-CT reconstruction in the treatment of posterior TPF and evaluated the influence on surgical decision-making. METHODS: CT images of 34 cases with a TPF involving the posterior column were included and digitally presented to a panel of five international observers at two intervals. At the first evaluation, only coronal, axial and sagittal images were shown. After an interval of at least three weeks, 3D-CT reconstruction images were added. During both surveys, observers were asked to classify the TPF according to the revised three-column classification (rTCC), as well as to define operative strategy. RESULTS: When using 2D images, overall multirated kappa value was 0.48, with an average pairwise agreement of 68%. After adding 3D images, overall multirated kappa value was 0.43, with average pairwise agreement of 67%. Hierarchical logistic regression of decision to operate on image condition (3D vs. 2D) shows an odds ratio of 2.01 (95% confidence interval, 1.11-3.67), Pâ¯=â¯.022. Increase in operative indication was seen mainly in posterolateral fractures. CONCLUSION: This study investigated the value of 3D classification in the treatment of posterior column TPF. Contrary to expectations, the addition of 3D images to the assessment did not reduce but rather appeared to increase operative indications, especially in fractures involving the posterolateral region.

The muscle footprint anatomy of the clavicle is described in various anatomical textbooks but research on the footprint variation is rare. Our goal was to assess the variation and to create a probabilistic atlas of the muscle footprint anatomy. 14 right and left clavicles of anatomical specimens were dissected until only muscle fibers remained. 3D models with muscle footprints were made through CT scanning, laser scanning and photogrammetry. Then, for each side, the mean clavicle was calculated and non-rigidly registered to all other cadaveric bones. Muscle footprints were indicated on the mean left and right clavicle through the 1-to-1 mesh correspondence which is achieved by non-rigid registration. Lastly, 2 probabilistic atlases from the clavicle muscle footprints were generated. There was no statistical significant difference between the surface area (absolute and relative), of the originally dissected muscle footprints, of male and female, and left and right anatomical specimens. Visualization of all muscle footprints on the mean clavicle resulted in 72% (right) and 82% (left) coverage of the surface. The Muscle Insertion Footprint of each specimen covered on average 36.9% of the average right and 37.0% of the average left clavicle. The difference between surface coverage by all MIF and the mean surface coverage, shows that the MIF location varies strongly. From the probabilistic atlas we can conclude that no universal clavicle exists. Therefore, patient-specific clavicle fracture fixation plates should be considered to minimally interfere with the MIF. Therefore, patient-specific clavicle fracture fixation plates which minimally interfere with the footprints should be considered.

INTRODUCTION: The management of segmental bone loss poses a significant clinical challenge. The purpose of this study was to conduct a retrospective evaluation of our experience in treating segmental bone loss, using Reamer-Irrigator-Aspirator (RIA)-harvested autologous bone graft. MATERIALS AND METHODS: Between June 2008 and March 2015, 81 patients were treated with the RIA technique for multiple purposes. Inclusion criteria for this study were skeletal mature patients with segmental bone loss, due to acute trauma or non-union, who were treated with RIA-harvested bone graft. Exclusion criteria were skeletal immaturity, pathological fractures and indications for the RIA system other than bone graft harvesting. The primary outcome parameter was clinical and radiographical bone healing. RESULTS: During the study period, 72 patients met the inclusion criteria. In total, 39 patients (54.2%) were classified as having clinical and radiographical bone healing. Although univariate analysis could not reveal any significant influence of specific risk factors to predict the outcome, there was a trend towards statistical significance for defect volume. Further analysis indeed revealed that smaller defect volumes (< 8 cm3) had a lower risk of non-union. CONCLUSIONS: In approximately half of our study population, the use of the RIA technique for autologous bone graft harvesting in cases of segmental bone loss resulted in a successful outcome with bone healing. Defect size seems to be a critical issue regarding the outcome. Although our results are less promising than previously published, the RIA technique has its place in the treatment algorithm of segmental bone defects.

Background: The present paper describes three cases where ER-REBOA® was used with partial aorta occlusion (AO), by performing a partial resuscitative endovascular balloon occlusion of the aorta or pREBOA, in an austere pre-hospital military environment.In addition, because no specific REBOA algorithm for pre-hospital environment exists yet, this paper seeks to fill this gap, proposing a new pragmatic REBOA algorithm. Methods: Belgian Special Operations Surgical Team applied REBOA in three patients according to a decisional algorithm, based on the MIST acronym used for trauma patients. Only 3 ml, in the first instance, was inflated in the balloon to get AO. The balloon was then progressively deflated, and reperfusion was tracked through changes of end-tidal carbon dioxide (EtCO2). Results: Systolic blood pressure (SBP) before ER-REBOA® placement was not higher than 60 mmHg. However, within the first 5 min after AO, SBP improved in all three cases. Due to the aortic compliance, a self-made pREBOA was progressively achieved while proximal SBP was raising with intravenous fluid infusion. Afterwards, during deflation, a steep inflection point was observed in SBP and EtCO2. Conclusions: ER-REBOA® is suitable for use in an austere pre-hospital environment. The MIST acronym can be helpful to select the patients for which it could be beneficial. REBOA can also be performed with pREBOA in a dynamic approach, inflating only 3 mL in the balloon and using the aortic compliance. Furthermore, while proximal SBP can be convenient to follow the occlusion, EtCO2 can be seen as an easy and interesting marker to follow the reperfusion.

A fracture-related infection (FRI) is an important complication that can lead to an increase in morbidity, mortality and economic costs. Preclinical in vivo models are critical in the evaluation of novel prevention and treatment strategies, yet it is important that these studies recapitulate the features of an FRI that make it such a clinical challenge. The aim of this systematic review was to survey the available preclinical models of FRIs and assess which of the key FRI-specific parameters are incorporated in these models. A comprehensive search was performed on July 1st 2017 in PubMed, Embase and Web of Science. Overall, 75 preclinical studies were identified, 97.3 % (n = 73) of which use Staphylococcus aureus as the causative microorganism. The most common mode for creation of bone instability is an osteotomy (n = 30; 40 %), followed by the creation of a defect (n = 26; 34.7 %). An actual fracture is created in only 19 studies (25.3 %). 12 (16 %) of the models include a time gap between bacterial inoculation and fixation to mimic the time-to-treatment in clinical open fracture scenarios. This systematic review reveals that animal models used in translational research on prevention and treatment of FRIs rarely incorporate all key clinical features in one model and that there is an over-representation of S. aureus in comparison to actual clinical epidemiology. To improve the relevance of these studies, existing preclinical models should be adapted or new models developed that better recapitulate the clinical condition of FRI.

OBJECTIVES: As well as debridement and irrigation, soft-tissue coverage, and osseous stabilization, systemic antibiotic prophylaxis is considered the benchmark in the management of open fractures and considerably reduces the risk of subsequent fracture-related infections (FRI). The direct application of antibiotics in the surgical field (local antibiotics) has been used for decades as additional prophylaxis in open fractures, although definitive evidence confirming a beneficial effect is scarce. The purpose of the present study was to review the clinical evidence regarding the effect of prophylactic application of local antibiotics in open limb fractures. METHODS: A comprehensive literature search was performed in PubMed, Web of Science, and Embase. Cohort studies investigating the effect of additional local antibiotic prophylaxis compared with systemic prophylaxis alone in the management of open fractures were included and the data were pooled in a meta-analysis. RESULTS: In total, eight studies which included 2738 patients were eligible for quantitative synthesis. The effect of antibiotic-loaded poly(methyl methacrylate) beads was investigated by six of these studies, and two studies evaluated the effect of local antibiotics applied without a carrier. Meta-analysis showed a significantly lower infection rate when local antibiotics were applied (4.6%; 91/1986) than in the control group receiving standard systemic prophylaxis alone (16.5%; 124/752) (p < 0.001) (odds ratio 0.30; 95% confidence interval 0.22 to 0.40). CONCLUSION: This meta-analysis suggests a risk reduction in FRI of 11.9% if additional local antibiotics are given prophylactically for open limb fractures. However, due to limited quality, heterogeneity, and considerable risk of bias, the pooling of data from primary studies has to be interpreted with caution.Cite this article: M. Morgenstern, A.

ABSTRACT
INTRODUCTION: One of the most challenging musculoskeletal complications in modern trauma surgery is infection after fracture fixation (IAFF). Although infections are clinically obvious in many cases, a clear definition of the term IAFF is crucial, not only for the evaluation of published research data but also for the establishment of uniform treatment concepts. The aim of this systematic review was to identify the definitions used in the scientific literature to describe infectious complications after internal fixation of fractures. The hypothesis of this study was that the majority of fracture-related literature do not define IAFF. MATERIAL AND METHODS: A comprehensive search was performed in Embase, Cochrane, Google Scholar, Medline (OvidSP), PubMed publisher and Web-of-Science for randomized controlled trials (RCTs) on fracture fixation. Data were collected on the definition of infectious complications after fracture fixation used in each study. Study selection was accomplished through two phases. During the first phase, titles and abstracts were reviewed for relevance, and the full texts of relevant articles were obtained. During the second phase, full-text articles were reviewed. All definitions were literally extracted and collected in a database. Then, a classification was designed to rate the quality of the description of IAFF. RESULTS: A total of 100 RCT's were identified in the search. Of 100 studies, only two (2%) cited a validated definition to describe IAFF. In 28 (28%) RCTs, the authors used a self-designed definition. In the other 70 RCTs, (70%) there was no description of a definition in the Methods section, although all of the articles described infections as an outcome parameter in the Results section. CONCLUSION: This systematic review shows that IAFF is not defined in a large majority of the fracture-related literature. To our knowledge, this is the first study conducted with the objective to explore this important issue. The lack of a consensus definition remains a problem in current orthopedic trauma research and treatment and this void should be addressed in the near future.

OBJECTIVES: The complication rate following operative treatment of patellar fractures remains high and is associated with a poor functional outcome. The primary goal of this study was to evaluate our functional outcome of patellar fracture osteosynthesis and define strategies to improve the outcome. The healthcare costs and utilization were calculated. METHODS: All demographic, clinical, radiographic variables and hospital-related costs of 111 patients with 113 surgically treated patellar fractures between January 2005 and December 2014 were analyzed. Fractures were grouped as either simple or complex. Functional outcome was assessed using Knee Injury and Osteoarthritis Outcome Score (KOOS). RESULTS: There were 67 simple fractures (59.3%) and 46 complex fractures (40.7%). The overall complication rate was 48.7%, including 19.5% implant-related complications. In 69 patients (61.1%), implants were removed. The outcome was rather poor, with considerable impairment in all KOOS subscales with the knee-related quality of life rated worst (median 62.5, IQR 37.5-81.25). Poor outcome correlated significantly with complex patellar fractures and extensive tension-band constructs. CONCLUSIONS: The operative treatment of patellar fractures was associated with a high complication rate, functional impairment and reduced quality of life. Complex patellar fractures and extensive tension-band constructs were identified as the main determinants of poor outcome and increased economic burden due to higher reinterventions rates. Strategies to reduce complications and improve outcome should focus on less onerous implants.

BACKGROUND: To optimize the treatment strategy and reduce treatment costs of proximal fifth metatarsal fractures, clinical and patient-reported outcome, and its determinants were addressed. METHODS: A retrospective adult cohort study including 152 proximal fifth metatarsal fractures: 121 nonoperatively and 31 operatively treated. In the operative group, 21 were zone 1 and 10 zone 2 fractures. Median follow-up was 37.5 (IQR 20.8-52.3) months with a minimal follow-up of 6 months. Twenty-three demographic, fracture, and treatment characteristics were assessed as well as the healthcare costs. Outcome was assessed using the patient files, anterior-posterior and oblique X-rays, foot function index (FFI), visual analog score (VAS), and SF-36 questionnaires. RESULTS: The median FFI, physical SF-36, and VAS scores did not significantly differ between nonoperatively and operatively treated patients. The FFI and physical SF-36 were predominantly affected by a history of mobility impairment and pre-existent cardiovascular diseases, whereas mental SF-36 correlated significantly with higher ASA-score. Overall complication rate was 5.9% (4.1 vs. 12.9%; p = 0.065, nonoperative vs. operative, respectively). Nonunion was recorded in only one (nonoperatively) treated patient. The total healthcare costs for operative treatment were 4.2 times higher compared to nonoperative treatment (1960 vs. 463 per patient, respectively). CONCLUSION: Overall, the clinical and patient-reported outcome was good. The foot function and quality of life were mainly affected by comorbidity, rather than fracture and treatment-related variables. Although nonoperatively treated patients indicated decreased mental quality of life, our study indicates that proximal fifth metatarsal fractures can safely be treated nonoperatively without the risk of nonunion, with fewer complications and lower healthcare costs. LEVEL OF EVIDENCE: 3.

PURPOSE: In the last 10 years, there has been an increasing tendency toward operative fixation of clavicle fractures. In this retrospective analysis, we will demographically assess all patients who sustained a clavicle fracture and were treated in our university hospital between 2004 and 2014. METHODS: We retrospectively updated our database and analyzed all adult patients who were diagnosed with a clavicle fracture in our hospital. The following parameters were included in the database: age, gender, Robinson classification, date of trauma, injury mechanism, time until surgery, and reason for delayed surgery. Descriptive statistics were used to describe differences between patient groups and linear regression was performed to identify trends over time. RESULTS: 667 patients were included for analysis. The mean age was 43 ± 17.7 years. The majority of clavicle fractures occurred due to bicycle injuries (35.3%) and these increased from 2004 until 2014 (r = 0.738, R² = 0.545, p = 0.009). Patients with a midshaft clavicle fracture were increasingly treated primarily surgically (r = 0.928, R² = 0.861, p < 0.0001). There was an increased ratio of delayed surgery in relation to age from the age of 16 (9.1%) until the age of 70 years (37.2%). CONCLUSIONS: There is an increasing number of fractures sustained by bicycle accidents and an increasing number of patients undergoing operative treatment. Middle-aged patients more often had delayed surgery compared with young adult patients. This could be due to an increased activity level of the elder population and the concomitant demand for a faster return to activities. LEVEL OF EVIDENCE: III, retrospective comparative study.

INTRODUCTION: The anatomy of the distal tibia accounts for reduced biomechanical stability and higher complication rates when treating distal tibiofibular fractures with an intramedullary tibia nail (IMTN). The goal of this study was to identify variables that affect the stability of IMTN. We assessed the value of additional fibular fixation, angular stable interlocking screws (ASLS) and multiplanar screw configuration in IMTN. PATIENTS AND METHODS: A retrospective cohort study was performed including 184 distal tibial fractures and associated fibula fracture treated with IMTN. Relevant demographic, fracture-related (type and level of the tibia and fibula fracture) and operative variables (depth of the nail, screw type and configuration, use of polar screws, fibular fixation) were studied. Coronal and sagittal alignment was assessed directly and 3-6 months after IMTN. Loss of reduction (LOR) was classified as 5-9° or ≥10°. RESULTS: 48.4% of the patients showed ≥5° LOR in one or both planes. Coronal LOR 5°-9° significantly correlated with low tibial fractures (p = 0.034), AO/OTA type 43 distal tibial fractures (p = 0.049), and sagittal LOR 5°-9° (p = 0.015). Although sagittal LOR 5°-9° was associated with fibular fractures (non-fixated suprasyndesmotic, p = 0.011), conversely we could not demonstrate the added value of (suprasyndesmotic) fibula fixation in IMTN. Coronal LOR ≥10° significantly correlated with AO/OTA type 43 distal tibial fractures (p = 0.009). In contrast to multiplanar configuration, we found a clear benefit of ASLS in distal IMTN locking. CONCLUSIONS: The level of the tibial fracture (AO/OTA type) and (suprasyndesmotic) fibular fractures were the main determinants of LOR after IMTN. ASLS was found to increase the stability of IMTN. Due to heterogeneity, however, we could not demonstrate the value of fibular fixation in IMTN. Therefore, a future prospective study with uniform treatment strategy for IMTN of distal tibiofibular fractures, with or without fixation of the fibula, is mandatory.

OBJECTIVES: Exact reconstruction of the depressed articular surface and stable subchondral fixation of the lateral tibial plateau (ORIF, "open reduction and internal fixation"). INDICATIONS: Tibial plateau fractures with involvement of the lateral column and depression of the articular surface. CONTRAINDICATIONS: Critical soft tissue. Severe osteoporosis. SURGICAL TECHNIQUE: Supine position, classical anterolateral approach, lateral submeniscal arthrotomy, visualisation of the fracture, osteotomy of the lateral tibial condyle. Reconstruction of the articular surface under visual control and temporary fixation with Kirschner wires. One or more 2.7 mm locking screws are placed subchondral for permanent stable fixation of the articular surface. If needed, the metaphyseal bone defect is filled with autologous or allogenic bone graft. The lateral tibial condyle is reduced and a 3.5 mm (variable angle) locking compression plate applied. Closure of fascia and skin in layers. FOLLOW-UP MANAGEMENT: Free range of motion, in case of residual instability of the collateral ligaments varus-valgus stabilizing brace, partial weight-bearing of 10-15 kg for 8 weeks, control computed tomography (CT) scan after 3 months. RESULTS: Since February 2014, a total of 23 lateral tibial plateau fractures were treated using the described technique; 4 patients were lost to follow-up and the 3month follow-up of 2 patients is not completed yet. After an average of 167 days, 11 patients had no complaints. At approximately 3 months postoperatively, 10 patients had full range of motion, 3 had a flexion deficit of at least 30°, and 2 patients had residual instability of the medial collateral ligament. One postoperative superficial infection was noted. At the 3 month CT, 10 of 17 patients showed successful reduction without significant articular steps or anatomical malalignment.

OBJECTIVES: Variable angle locking compression plates allow for lateral buttress and support of the posterolateral joint surface of tibial plateau fractures. This gives room for improvement of the surgical 3-column classification approach. Our aim was to revise and validate the 3-column classification approach to better guide the surgical planning of tibial plateau fractures extending into the posterolateral corner. METHODS: In contrast to the 3-column classification approach, in the revised approach the posterior border of the lateral column in the revised approach lies posterior instead of anterior of the fibula. According to the revised 3-column classification approach, extended lateral column fractures are defined as single lateral column fractures extending posteriorly into the posterolateral corner. CT-images of 36 patients were reviewed and classified twice online according to Schatzker and revised 3-column classification approach by five observers. The intraobserver reliability was calculated using the Cohen's kappa and the interobserver reliability was calculated using the Fleiss' kappa. RESULTS: The intraobserver reliability showed substantial agreement according to Landis and Koch for both Schatzker and the revised 3-column classification approach (0.746 vs. 0.782 p = 0.37, Schatzker vs. revised 3-column, respectively). However, the interobserver reliability of the revised 3-column classification approach was significantly higher as compared to the Schatzker classification (0.531 vs. 0.669 p < 0.01, moderate vs. substantial agreement, Schatzker vs. revised 3-column, respectively). CONCLUSIONS: With the introduction of variable angle locking compression plates, the revised 3-column classification approach is a very helpful tool in the preoperative surgical planning of tibial plateau fractures, in particular, lateral column fractures that extend into the posterolateral corner. The revised 3-column classification approach is rather a practical supplement to the Schatzker classification. It has a significantly higher interobserver reliability as compared to the Schatzker classification, most likely due to the more simple nature of the revised 3-column classification approach.

We describe the step-by-step process of a corrective osteotomy using 3D printed patient specific guides. Before surgery, bilateral computed tomography (CT) scans are made to plan correction in the affected limb. The digital pre-planning defines the location of the K-wires, drill holes, and the osteotomy site(s). Subsequently, a 3D printed patient specific guide is applied, which indicates the exact position of these drill holes and the osteotomies. This increases the accuracy of the surgery by means of patient specific fit of the guide. During surgery an incision is made and the guide is applied on the bone, which allows the surgeon to perform a very precise osteotomy. Next, the bone is reduced either directly using the plate and marked drill holes, or indirectly using a second reduction guide. In the latter case, the previously drilled K-wires are used to adequately position the reduction guide. Fixation of the bone fragments using plating osteosynthesis finalizes the process. Although this technique has its specific limitations, it might serve as a powerful tool in the treatment of malunion of both articular and nonarticular fractures of the limb.

Fracture fixation devices are implanted into a growing number of patients each year. This may be attributed to an increase in the popularity of operative fracture care and the development of ever more sophisticated implants, which may be used in even the most difficult clinical cases. Furthermore, as the general population ages, fragility fractures become more frequent. With the increase in number of surgical interventions, the absolute number of complications of these surgical treatments will inevitably rise. Implant-related infection and compromised fracture healing remain the most challenging and prevalent complications in operative fracture care. Any strategy that can help to reduce these complications will not only lead to a faster and more complete resumption of activities, but will also help to reduce the socio-economic impact. In this review we describe the influence of implant design and material choice on complication rates in trauma patients. Furthermore, we discuss the importance of local delivery systems, such as implant coatings and bone cement, and how these systems may have an impact on the prevalence, prevention and treatment outcome of these complications.

BACKGROUND: The complex disabilities of children with profound intellectual and multiple disabilities (PIMD) impede their presentation of peer directed behaviours. Interactions with typically developing peers have been observed to be more frequent than those with peers with PIMD. The typically developing peers with whom people with PIMD have frequent contact are their siblings. In this study, the amount of peer directed behaviours was compared between an interaction with a sibling and an interaction with a peer with PIMD. In addition, the attention directing strategies of the siblings, and how these affect the presentation of peer directed behaviours, were examined. METHOD: Thirteen children and young people with PIMD, who had a typically developing sibling, were identified. For each of these thirteen children, a peer with PIMD and a sibling were selected. The child with PIMD was observed together with a peer with PIMD and together with a sibling. In both conditions, video observations were conducted. A coding scheme for the peer directed behaviours of the children and young people with PIMD and a coding scheme for the attention directing behaviours of the siblings were used. Descriptive, comparative and sequential analyses were conducted. RESULTS: Significantly, more peer directed behaviours of the children with PIMD were observed in the condition with the sibling (30.76%) compared with that of the condition with the peer with PIMD (13.73%). The siblings presented attention directing behaviours in 30% of the time; the most frequently used was nonverbal behaviour. When the siblings presented a combination of verbal and nonverbal attention directing behaviours, they elicited multiple peer directed behaviours in the children and young people with PIMD. CONCLUSIONS: Persons with PIMD interact more with their siblings compared with their peers with PIMD. Interacting with siblings may probably be more motivating and encouraging. Presenting a combination of verbal and nonverbal behaviours attracts more attention of the persons with PIMD.

BACKGROUND: The multiple and complex disabilities of persons with profound intellectual and multiple disabilities (PIMD) form a barrier for peer interactions and peer-directed behaviours. In this study, we further explore the nature of peer-directed behaviours in persons with PIMD and its relationship with social scaffolding behaviour of direct support workers (DSWs). METHODS: Fourteen dyads of children with PIMD, who knew each other for at least 12 months, participated. They were sitting in close proximity while they were filmed with and without the presence of the DSW. Video recordings were coded continuously making use of observation schemes for the peer-directed behaviours of the children and the peer interaction influencing behaviours of the DSW. RESULTS: Significantly more singular peer-directed behaviour (without DSW: 18.00%; with DSW: 3.81%) was observed than multiple peer-directed behaviour (without DSW: 4.01%; with DSW: 0.52%). The amount of time the singular and multiple peer-directed behaviours were observed was significantly lower in the presence of a DSW. When the DSW shows peer interaction influencing behaviour, it was mostly social scaffolding behaviour (2.17%). The conditional probability of observing social scaffolding behaviour in the 10 s following on singular peer-directed behaviour was 0.02 with a Yule's Q of 0.04 and following on multiple peer-directed behaviour 0.04 with a Yule's Q of 0.33. CONCLUSION: The way in which peer interactions in children with PIMD are defined could have an impact on the amount of observed peer-directed behaviours and on the effect of the social scaffolding behaviours presented by DSW.
