Orthopedic trauma surgeon in Sierra Leone: how to keep one’s head over water

PurposeDeveloping a guideline for orthopedic trauma surgeons working in civilian trauma hospitals in low-income countries.MethodsThis is a retrospective data analysis in a non-governmental organizational trauma hospital in Sierra Leone, Africa. Trauma victims (282), with 349 fractures, were admitted to the hospital 10/2015–01/2016. The incidence of open and closed fractures and the use of implants were evaluated.ResultsThe most common fractures were open and closed tibial shaft fractures and closed femoral shaft fractures in adults, and closed supracondylar humerus fractures in children. The most used implants were external fixators, K-wires, and intramedullary nails. External fixators were used for open fractures, K-wires for closed fractures in children, hand and foot, and nails for closed fractures of the lower extremity in adults. Plates were used the least and mostly for fractures of the upper extremity, the proximal tibia and malleolar region in adults. The complication rate was 5.67%.ConclusionSurgeons in low-income country trauma hospitals should treat conservatively on outpatient basis only, to reduce the amount of stationary patients. Open fractures should be treated with external fixators, and closed fractures in children, hand and foot, with K-wires. Closed fractures in adults of the lower extremity should be nailed, and closed fractures in adults of the upper extremity can be treated with plates.

Preoperative Evaluation of Intramedullary Tibial Nail Measurements-A Review of the Literature and a New Technique Using Contralateral Radiographs and Digital Planning.

Introduction:An accurate selection of tibial nail and screws measurements is paramount in purpose to achieve proper tibial fracture reduction and fixation, avoid irritation of the soft-tissue envelope, and enable extraction of the nail in the future, if needed. To this date, many methods were suggested to determine the length and diameter of an intramedullary tibial nail, preoperatively and intraoperatively. Each method has its disadvantages, and most are lacking in accuracy. Digital aids are currently available for preoperative planning for many types of surgeries.Methods:Retrospectively, 27 patients operated for diaphysial tibial fracture intramedullary nailing were selected. The contralateral leg was imaged using AP and lateral radiograph views. Six orthopaedic trauma surgeons used the TraumaCad program (Voyant Health) to plan the appropriate nail and distal locking screws measurements, while blinded from the actual hardware used in the operation. Later, they also conducted quality review regarding the operation carried out and suggested correction in measurements of the hardware. Intra-observer and inter-observer reliability was calculated.Results:The inter-correlation coefficient for the planned nails was 0.97 and 0.84 (P < 0.001) in AP view for length and diameter, respectively, and similarly 0.98 and 0.86 (P < 0.001) in lateral view. The interclass correlation coefficient (ICC) for the locking screws length was 0.7 (P < 0.02) and 0.82 (P < 0.01) for the proximal and distal medio-lateral screws, respectively, and 0.9 (P < 0.001). The ICC between AP and lateral views was 0.98 for length and 0.96 for diameter (P < 0.001). The scores and corrections given by the examiners to the actual selected nail were ICC of 0.98 and 0.96 (P < 0.001) for length and diameter, respectively. The examiners suggested they would correct, post-factum, the length of the nail in average 28% and the diameter in average 30%. The average observer resulted in ICC of 0.94 and 0.91 (P < 0.001) in length and only 0.77 and 0.67 (P < 0.001) in diameter (AP and lateral views, respectively) when comparing the actual nail used and the post-factum plan.Conclusion:Preoperative planning of tibial fractures' nailing using imaging of the contralateral leg and a digital graphic planning program is an accurate and reliable method. It may serve to reduce errors, surgical time, and radiation dose in the operating room. This method could also be applied for surgical debriefing.

Relative Incidence of Proximal Fibula Fractures with Tibial Plateau Fractures: An Investigation of 354 Cases.

We aimed to investigate the incidence of proximal fibula fractures in patients with tibial plateau fractures and to identify risk factors for such combined injuries. From January 2011 to December 2015, 354 patients with tibial plateau fractures who had been admitted to a level 1 trauma center were retrospectively evaluated by an orthopaedic trauma surgeon and two skeletal radiologists. Anteroposterior plain radiography and computed tomography (CT) were used to characterize the injuries, and the incidence of associated proximal fibula fractures was determined. The tibial plateau fractures were classified according to the Schatzker's and three-column classifications. Associated proximal fibula fractures were simultaneously classified with a new fibula fracture classification system. Finally, we determined whether there were statistically significant associations between the presence of a proximal fibula fracture and different types of tibial plateau fractures, as well as sex and age. Proximal fibula fractures were detected in 192 (54.24%) patients using plain radiography and in 215 (60.73%) patients using CT. Logistic regression analysis indicated an increasing trend in the incidence of fibula fractures detected by the CT-based three-column classification system as follows: "age × sex > three columns > age > single posterior column > lateral column + posterior column > medial column + posterior column > medial column + lateral column > single lateral column > single medial column." Proximal fibula fracture associated with tibial plateau fracture is a common phenomenon worthy of attention. In women, age increases the likelihood of complex tibial plateau fractures, particularly those involving the posterolateral articular surface and diaphysis, as well as the likelihood of developing proximal fibula fractures. This s Level IV diagnostic study.

Orthopaedic Trauma Quality Measures for Value-Based Health Care Delivery: A Systematic Review.

To assess the current portfolio of quality measures and candidate quality measures that address orthopaedic trauma surgery. We systematically reviewed the National Quality Forum, the Agency for Healthcare Research and Quality, and the Quality Payment Program for quality measures relevant to fracture surgery. We also searched MEDLINE/PubMed, Embase/Scopus, and Cochrane libraries. Clinical practice guidelines were included as candidate quality measures if their development was in accordance with the Institute of Medicine criteria for development of clinical practice guidelines, were based on consistent clinical evidence including at least one Level I study, and carried the strongest possible recommendation by the developing body. We categorized the measures as structure, process, or outcome domains according to the framework described by Donabedian. From the 3809 articles initially identified and screened, a total of 189 combined quality or candidate quality measures were extracted from our review. With regard to the Donabedian framework, there were a total of 7% (13/189) structure, 52% process (99/189), and 41% (77/189) outcome measures identified. As quality measures progressively inform reimbursement in value-based health care models, quality measures evaluating the care of patients sustaining a fracture will become increasingly relevant to orthopaedic trauma surgeons.

The Relevance of the Judet and Letournel Acetabular Fracture Classification System in the Modern Era: A Review.

The Judet and Letournel acetabular fracture classification system, based on the idea of bicolumnar support of the acetabulum, was first described in a landmark article published in the 1960s. It has stood the test of time and continues to be the preferred method for describing acetabular fractures for the majority of orthopaedic trauma surgeons. Still, there have been attempts to modify or replace Letournel system since its introduction for a variety of reasons, chief among them a perceived inability of the classification system to account for a number of transitional fracture patterns and injury modifiers that may affect surgical decision making and patient outcomes. In this review, we present the literature related to the Judet and Letournel acetabular fracture classification system, over 50 years after its first formal description. We summarize its strengths, weaknesses, and its place in our current understanding of acetabular fractures and their recommended management.

Pertinence des classifications Garden, AO, et « simplifiée 2 stades » pour les fractures cervicales vraies du fémur proximal

IntroductionSuccessful treatment starts by accurate classification of pathology, but there is no conclusive, reliable and universally accepted method for classification of intracapsular femoral neck fractures. As a perfect classification should have high intra- and inter-observer agreement, this study aims to access reliability of three classification systems: Garden, AO and simple II stage classification. Materials and methodsFour orthopaedic trauma surgeons (two of them professors) and two senior orthopaedic trauma residents were invited to evaluated 136 blinded anterior-posterior and lateral X-rays of patients with femoral neck fractures. Observers classified fractures according to IV stage Garden, AO and simple II stage classifications. The exercise was repeated after one month on same but randomised X-rays. Cohen kappa was used to measure inter- and intra-observer agreement. Fleiss kappa was used to access multi-rater agreement. ResultsAO classification showed an overall agreement of 0.22 (fair agreement). Garden classification had overall reliability slightly higher than AO, but matching same fair agreement group (0.33). II stage classification provided the highest estimates: from 0.35 (fair agreement) to 0.83 (almost perfect agreement) and multi-rater agreement of 0.50 (moderate agreement). There was seen no difference in intra- and inter-observer agreement between observer groups (professors, trauma surgeons and trauma residents). DiscussionAll three classification systems showed equal adoption among differently experienced observer groups. Despite this finding, IV stage Garden and AO classifications should be avoided in clinical use because of poor reproducibility. Only simple II stage classification showed sufficient intra- and inter-observer reliability. Level of evidenceIV, retrospective study.

Peri-operative outcomes for ORIF of acetabular fracture in the elderly: Comparison with displaced intracapsular hip fractures in a national pelvic and acetabular referral centre over 5 years

IntroductionThe increasing incidence of acetabular fractures in the elderly and the fracture complexity seen in this cohort represents one of the greatest challenges faced by trauma orthopaedic surgeons today. There are no formal guidelines of best practice in the treatment of these patients. Management options vary from non-operative, acute ORIF, and/or total joint replacement. Although surgical intervention allows for earlier mobilization and avoidance of the complications of prolonged bedrest, the patients ability to tolerate what is often major surgery is always of concern. This is in stark contrast to intracapsular hip fractures, (a fracture within the same joint), where acute surgery is recommended in virtually all cases. ObjectivesThis study was undertaken to evaluate the peri-operative outcomes for geriatric patients undergoing acetabular ORIF and hemiarthroplasty to assess if there is a significant difference in early outcome parameters. DesignThis is a retrospective case–control study. SettingThis study was performed in the National Centre for Pelvic and Acetabular surgery. Patients42 age- and sex-matched patients with comparable ASA grades were included in each arm of the study. Patient selection in the acetabular ORIF group was consecutive patients managed operatively in the centre during the period 2010–2015. The selection for the hemiarthroplasty group was by random selection of age- and sex-matched patients undergoing hemiarthroplasty during the same period. Main outcome measurementsThe primary outcomes that were proposed prior to the study being performed was perioperative mortality and post-op complications. Secondary outcomes were operating times, blood loss and need for ICU admission. ResultsA significant difference between the two cohorts was observed with operative times, blood loss, need for transfusion, and need for ICU admission, all higher in the acetabular ORIF group. There was no significant difference in mortality or post-op infection. ConclusionsOur paper supports the concept that acute ORIF of acetabular fractures, with appropriate peri-operative support, can be undertaken safely. There is no difference in the major peri-operative outcomes of mortality or infection when compared with hip fracture patients requiring hemiarthroplasty.

The reliability of a Garden, AO and simple II stage classifications for intracapsular hip fractures

Non-technical training in orthopedic surgery: An unrecognized need

Objectives: Surgical safety has become a raising concern over the past few decades. Many studies have shown that it is correlated to nontechnical performance rather than clinical expertise, and it can be improved if nontechnical competencies are combined with technical training in the surgical profession. The primary purposes of this study were to assess and prioritize the perceived needs of orthopedic surgeons for nontechnical skills for orthopedic surgeons in correlation to years of experience. Methods: An online survey was sent to 200 AOTrauma members in the Middle East clearly stating the study purposes and volunteer participation. A 5-point Likert scale was used to collect surgeons' ratings of the selected nontechnical topics. Results: One-hundred and nine of 200 (54.5%) invited participants responded. More than half (65.1%) being surgeons with >10 years of experience. The majority (92%) of respondents emphasized the importance of nontechnical skills training for orthopedic surgeons. Of the enlisted topics, professionalism and patient privacy scored the highest priority for junior surgeons, while more experienced surgeons ranked patient safety and teamwork as their top two desired topics. An interesting finding was that medicolegal training was rated as an increasing need as more surgical experience was gained. Conclusions: This study highlights the demand for nontechnical skills training from the orthopedic trauma surgeons' perspective. The results showed that topics such as patient safety essentials, professionalism, teamwork, and medicolegal issues came on the top of the list. Addressing this demand by creative and specialty-focused nontechnical skills courses will help to improve patient care.

Current trends in the management of flail chest and the perceived role of the surgeon

Background: Flail chest injuries typically occur in poly-traumatized patients and are often associated with prolonged hospital stays and high rates of morbidity and mortality. Despite multiple studies showing significantly improved outcomes with surgical fixation, the surgical community has been slow to adopt rib fixation as a part of practice and, as a result, many of these patients never undergo surgical fixation. Purpose: The purpose of this study is to determine the percentage of flail chest injuries that are being treated with surgical fixation in the United States. In addition, a survey of orthopedic trauma surgeons was conducted to assess their perception of the role of orthopedics in the treatment of patients with flail chest injuries. Methods: Patients diagnosed with a flail chest injury were identified using the National Inpatient Sample (NIS) database between 2001 and 2012 and divided into two groups based on whether or not surgical fixation of the chest wall was performed. In addition, we distributed a survey questionnaire to orthopedic trauma surgeons focusing on each individual's experience with rib fracture fixation both in training and practice. Results: A total of 45,202 patients with a flail chest injury were identified using the NIS database between 2001 and 2012. Of these, 2.1% underwent surgical fixation of the chest wall with an increase in rate of fixation from 0.8% to 3.3% over the study period. According to our survey, only 20% of orthopedic trauma surgeons performed any rib fracture fixation cases in training, and only 24% perform rib fracture fixation cases in their practice. Of those who do not perform rib fracture fixation, 72% would consider doing so if they received additional training on the topic. Of all participants surveyed, 60% believed that rib fracture fixation should be a part of the orthopedic residency curriculum and 89% believed that it should be a part of the orthopedic trauma fellowship curriculum. Conclusions: Very few flail chest injuries are being treated with surgical fixation despite the emerging literature showing improved outcomes when compared to nonoperative management. Our survey shows that there is significant interest in incorporating rib fracture fixation into surgeons' training curriculum, as well as providing specialized workshops for practicing surgeons. We hope this work encourages the surgical community to embrace rib fracture fixation as a part of our specialty so that patients with flail chest injuries receive optimal care.

Single lateral locked plate can be an effective implant in providing fracture stabilization of bicondylar tibial plateau fractures

Background: Bicondylar tibial plateau fractures present a therapeutic challenge to the orthopaedic trauma surgeon, both in terms of the osseous injury as well as the concomitant soft-tissue insult. Double Plating with single incision or dual incisions provide more insult to the compromised soft tissue. However, single locking plate combines the technical advantages of an angular stable plate with those of the modern biological plating technique. Methods: The Study was held at Razi Orthopedic hospital in Kuwait. Between May 2012 and November 2013, 20 patients with a mean age of 37.65 years (Range from 24– 57 years) with bicondylar tibial plateau fractures with or without metaphyseal extension. Patients were diagnosed clinically, checked with standard X-rays, CT was done for all cases. Patients were treated by single lateral anatomically contoured locked plate through LISS or Polyaxial locking plate systems with or without additional screws from medial side. Radiological evaluation and functional assessment was done according to the Rasmussen Knee score. Patients were followed-up for an average of 12 months. Results: Union was achieved in all patients with a mean knee range of motion of 1.5°-130° (range: 0°-10° for extension lag, range: 100°-135° for flexion). The mean Functional Rasmussen Knee score at 6 month follow up (25.32±1.53 SD) ranged from (23.0-28.0). The mean Functional Rasmussen Knee score at last follow-up was (28.33±1.57 SD) ranged between (25.0-30.0) with significant P value (P value&lt;0.001). The mean Anatomical Rasmussen Knee score at 6 month follow up (16.11±1.56 SD) ranged from (14.0-18.0). The mean Anatomical Rasmussen Knee score at last follow-up was (16.67±1.37 SD) ranged from (14.0-18.0) with insignificant P value (P value 0.096 ). Of the 20 patients, one patient had wound related problems, one patient had preoperative compartment syndrome, one patient suffered from hardware irritation and one patient had fixation failure upon which revision with double plating done for him. Conclusions: Surgical treatment of bicondylar tibial plateau fractures with the single lateral locked plate that was evaluated in our study can lead to a good functional and anatomical outcome and considered an effective system for providing fracture stabilization provided that the correct surgical technique is used. Awareness of potential hardware complications is essential.

The association between patient education level and economic status on outcomes following surgical management of (fracture) non-union

BackgroundSocioeconomic disparities are an inherent and currently unavoidable aspect of medicine. Knowledge of these disparities is an essential component towards medical decision making, particularly among an increasingly diverse population. While healthcare disparities have been elucidated in a wide variety of orthopaedic conditions and management options, they have not been established among patients who present for treatment of an ununited fracture. The purpose of this study is to answer the following questions: 1) Following surgical management of (fracture) non-unions, are there differences in outcomes between differing ethnic groups? 2) Following surgical management of (fracture) non-unions, are there differences in outcomes between patients with differing education levels? 3) Following surgical management of (fracture) non-unions, are there differences in outcome between patients with differing incomes? MethodsBetween September 2004 and December 2017, operatively treated patients who presented with a long bone fracture non-union were prospectively followed. These patients presented with a variety of fracture non-unions that underwent surgical intervention. Sociodemographic factors were recorded at presentation. Long-term outcomes were evaluated using the Short Musculoskeletal Function Assessment (SMFA), pain scores, post-operative complications and physical exam at latest follow up. The SMFA is a 46-item questionnaire, assessing patient functional and emotional response to musculoskeletal ailments. ResultsThree-hundred-twenty-nine patients met inclusion criteria. Patients with a lower education had worse long-term functional outcomes (P < 0.001) and increased pain scores (P = 0.002) at latest follow-up. Patients who made less than $50,000 annually had worse long-term functional outcomes (P = 0.002) and reported higher pain scores (P = 0.003) following surgical management of (fracture) non-unions. Multiple linear regression demonstrated education level to be an independent predictor of long-term functional outcomes following surgical management of (fracture) non-unions (B= -0.154, 95% Confidence Interval [CI]=-10.96 to -1.26, P = 0.014). No differences existed in outcomes or pain scores between those of different ethnic groups. No differences existed regarding post-operative complications and time to union between patients of different ethnic groups, educational levels and income status. ConclusionPatients with lower education levels and individuals who make less than $50,000 annually have worse functional outcomes following surgical management of (fracture) non-unions. Orthopaedic trauma surgeons should therefore be aware of these disparities, and consider early interventions aimed at optimizing patient recovery in these subsets.

Patient-reported quality of life and pain after permissive weight bearing in surgically treated trauma patients with tibial plateau fractures: a retrospective cohort study

IntroductionA Dutch survey among orthopedic surgeons and trauma surgeons showed that almost 90% of the surgeons do not follow protocols regarding the weight bearing aftercare for tibial plateau fractures. Clinical studies comparing permissive weight bearing (PWB) versus restricted weight bearing (RWB) after surgically treated tibial plateau fractures are not available. The aim of this study was to inventory potential differences in quality of life and pain, and number of complications in patients with surgically treated tibial plateau fractures who followed a PWB regime, relative to those that followed a RWB regime.Materials and methodsThis retrospective cohort study included surgically treated trauma patients with tibial plateau fractures, who underwent rehabilitation according to PWB or RWB between 2005 and 2015. Data such as demographics, patient-reported quality of life and pain, and patient outcome were collected.ResultsThis cohort study included 91 patients with a tibial plateau fracture (31 and 60 patients in the PWB and RWB groups respectively). No significant between-group differences in either age or gender were found. However, a significant difference in fracture type was found between groups, (p = 0.04). No significant differences were found in either patient-reported SF-12 or VAS scores between the PWB group and RWB group. Time to full weight bearing was significantly shorter in the PWB than in the RWB group, i.e., 14.7 versus 20.7 weeks, (p = 0.02). No significant differences were found regarding postoperative complications between the PWB and the RWB groups, i.e., 6.5% versus 10.0%, respectively.ConclusionPWB after surgically treated tibial plateau fractures is safe and is related to a significantly reduced time to full weight bearing with no significant differences in patient-reported quality of life and pain or complication rates.

Treatment of distal clavicle nonunion with and without bone grafting

The management of distal clavicle nonunion represents a challenging task for orthopaedic trauma surgeon. Both the choice of the implant and whether a bone graft is needed are controversial points which must be addressed. Particularly, in the case of a hypertrophic nonunion, grafting may not necessarily be needed, but given a poor underlying biological environment, a bone graft becomes necessary in order to enhance fracture healing.We report the case of a 62-year-old patient who came to us with a hypertrophic nonunion of the left distal clavicle. She was initially treated with a hook plate without bone grafting. After an early peri-implant fracture she was treated again with anatomical S-shaped locking plate associated with autologous cancellous bone graft.

Reduction of routine radiographs in the follow-up of distal radius and ankle fractures: Barriers and facilitators perceived by orthopaedic trauma surgeons.

Rationale, aims, and objectivesStudies suggest that routine radiographs during follow‐up of distal radius and ankle fractures result in increased radiation exposure and health care costs, without influencing treatment strategies. Encouraging clinicians to omit these routine radiographs is challenging, and little is known about barriers and facilitators that influence this omission. Therefore, this study aims to identify barriers and facilitators among orthopaedic trauma surgeons that might prove valuable towards the design of a deimplementation strategy.MethodsA mixed‐method approach was used. First, interviews were conducted with orthopaedic trauma surgeons and patients (n = 16). Subsequently, a questionnaire was developed. This questionnaire was presented to 228 orthopaedic trauma surgeons in the Netherlands. Regression analyses were performed in order to identify which variables were independently associated to the decision to stop performing routine radiographs 6 and 12 weeks after trauma if proven not effective in a large randomized controlled trial.ResultsIn total, 130 (57%) respondents completed the questionnaire. Of these, 71% indicated they would stop ordering routine radiographs if they were proven not effective. Three facilitators were independent predictors for the intention to omit routine radiographs: This will “lead to lower health care costs” (Odds Ratio [OR]: 5.38 and 4.38), the need for “incorporation in the regional protocol” (OR: 3.66 and 2.66), and this will “result in time savings for the patient” (OR: 4.84).ConclusionsWe identified three facilitators that could provide backing for a deimplementation strategy aimed at a reduction of routine radiographs for patients with distal radius and ankle fractures.

A simplified classification of proximal femoral fractures improves accuracy, confidence, and inter-reader agreement of hip fracture classification by radiology residents.

To demonstrate the effect of teaching a simplified treatment-based classification of proximal femoral fractures on the accuracy, confidence, and inter-reader agreement of radiology residents. The authors hypothesize that these measures will improve after viewing an educational presentation. Three radiology residents independently classified 100 operative proximal femoral fractures, both before and after viewing a 45-min educational video describing the simplified classification scheme, with a washout period of at least 12weeks between sessions. Based on the gold standard established by consensus of two radiologists and an orthopedic trauma surgeon utilizing intraoperative fluoroscopic imaging, operative reports, and pre-procedural imaging, accuracy of classification was calculated for each reader before and after viewing the educational video. Reader confidence was recorded on a 0-10 scale, and inter-reader agreement was calculated with Fleiss's kappa. McNemar's test was used to compare accuracy, a paired t test was used to compare confidence, and the Z-test was used to compare kappa values after bootstrapping to determine the standard error of the mean. The study cohort included 60/100 females, with a mean age of 76.6years. The pooled classification accuracy was initially 65%, which improved to 80% in the second reading session after viewing the educational video (p < 0.0001). Confidence improved from 6.9 initially to 8.6 (p < 0.0001). Inter-reader agreement improved from a kappa of 0.45 (moderate agreement) to 0.74 (substantial agreement) (p < 0.0001). A simplified treatment-based classification of proximal femoral fractures is easily taught to radiology residents and resulted in increased accuracy, increased inter-reader agreement, and increased reader confidence.

Experimental Validation of the Radiographic Union Score for Tibial Fractures (RUST) Using Micro-Computed Tomography Scanning and Biomechanical Testing in an in-Vivo Rat Model

The Radiographic Union Score for Tibial fractures (RUST) and the modified version of the system, mRUST, are popular standards for assessing fracture-healing progress with use of radiographs. To our knowledge, this is the first study to experimentally validate the ability of RUST and mRUST to accurately assess bone-healing progression with use of both micro-computed tomography (micro-CT) scanning and biomechanical testing. Adult male rats (n = 29) underwent osteotomy with a midshaft fracture gap repaired with use of a polyetheretherketone plate. Anteroposterior and lateral radiographs were made of the repaired femora prior to rat death at end points of 5, 6, 7, 8, 9, and 17 weeks, and 2 fellowship-trained orthopaedic trauma surgeons independently assigned RUST and mRUST scores to repaired femora. The repaired and intact contralateral femora were then dissected. Bones underwent dissection, micro-CT scanning, and biomechanical torsion testing at the end points. RUST scores ranged from 5 to 12 and mRUST scores ranged from 5 to 16. Intraclass correlation coefficients (ICCs) were 0.89 (95% confidence interval [CI]: 0.78 to 0.94) for RUST and 0.86 (95% CI: 0.74 to 0.93) for mRUST, which fall within the "almost perfect agreement" category for ICCs. Spearman rank correlation coefficients (RS) showed correlation of RUST (RS range, 0.456 to 0.818) and mRUST (RS range, 0.519 to 0.862) with micro-CT measurements of mineralized callus volume (BV), total callus volume (TV), and BV/TV ratio, but less so with bone mineral density (BMD). Additionally, RUST (RS range, 0.524 to 0.863) and mRUST (RS range, 0.434 to 0.850) were correlated with some biomechanical properties. A RUST score of 10 or an mRUST score of 15 may be considered the threshold above which a plated bone is "healed" because, at these scores, 120% or 140% of failure torque, respectively, was achieved by the repaired femora as compared with the intact contralateral femora. RUST and mRUST both show strong statistical correlations with micro-CT and biomechanical parameters. RUST and mRUST scoring systems provide clinicians with validated, reliable, and available tools to assess the progress of fracture-healing.

Evolution in Management of Tibial Pilon Fractures.

Tibial plafond, or pilon, fractures can be some of the most difficult fractures to manage. As they are often associated with high-energy trauma, both the soft tissue involvement and the comminuted fracture pattern pose challenges to fixation. Furthermore, the complex anatomy and trauma to the cartilage at the time of injury predispose pilon fractures to poor functional outcomes and high rates of posttraumatic arthritis. This review will discuss the recent developments in the treatment of tibial pilon fractures. Historically, surgical management of pilon fractures has been associated with high rates of complications, including wound complications, infections, nonunions, and even the need for amputation. In response, staged protocols were created. However, recent studies have called this into question, demonstrating low wound complications with early definitive fixation. Additional studies are evaluating adjuvants to minimize wound complications, including the use of vancomycin powder and oxygen supplementation, while another study challenges the 7-cm myth regarding the distance needed between skin incisions. Additional research has been focused on alternative methods of managing these complex, and sometimes non-reconstructable, injuries with the use of external fixation, minimally invasive internal fixation, and primary arthrodesis. Tibial pilon fractures remain difficult to treat for even the most skilled orthopedic trauma surgeons. With improvements in surgical techniques and implants, complication rates have declined and outcomes have improved; however, the overall prognosis for these injuries often remains poor.

Does altering projection of the fractured clavicle change treatment strategy?

Shortening of the fractured clavicle is proposed and debated as an indicator for surgical intervention. There is no standardized or uniform method for imaging and measuring shortening. Different methods and techniques can lead to different measured outcomes. However, the question remains whether a difference in measured shortening using a different technique has any short-term clinical relevance in terms of treatment strategy. The aim of this study was to investigate whether a different projection of the same midshaft clavicular fracture would lead to a different choice in treatment strategy. Thirty-six AO-OTA (Arbeitsgemeinschaft für Osteosynthesefragen-Orthopaedic Trauma Association) 15A.1-15A.3 midshaft clavicular fractures were digitally reconstructed into radiographs using both 15° caudocranial and 15° craniocaudal projections. The 72 projections were rated in random order by 23 orthopedic trauma or upper-extremity surgeons on the need for either conservative or operative treatment. On average, the raters altered their treatment strategy with a different projection of the same midshaft clavicular fracture 12.2 times among the 36 cases (33.9%), ranging from 5 times (13.9%) to 19 times (52.8%). A statistically significant increase in choice for surgical treatment was identified when using the 15° caudocranial projection (P = .01). This study reveals the influence the projection of the midshaft clavicular fracture has on the surgeon's decision of treatment strategy. The decision changes from operative to nonoperative or vice versa in 33.9% of the cases.

Staged internal plate fixation of severe lower extremity fractures that use a temporary external fixator for the initial treatment as an intraoperative retention tool: a technical note.

Staged treatment for severe lower extremity fractures is coming into widespread use, and some reports have described internal fixation (IF) using a temporary external fixator for primary care as an intraoperative retention tool. However, the infection risk with this procedure has not been examined sufficiently. To our knowledge, this article is the first report focusing exclusively on this specific surgical technique. A key point of our developed protocol for internal plate fixation with this technique to avoid postoperative infection is a precisely structured sterilization procedure, which required multiple changes of sterile surgical gloves. In all 19 fractures treated with our set protocol, postoperative infection did not occur. In this regard, however, a goal of definitive IF at the time of initial treatment is essential for this specific procedure. This technique could help orthopaedic trauma surgeons to import a temporary external fixator into the operative field for definitive IF, with less concern regarding risk of infection.
