Comparative analysis of external locking plate and combined frame external fixator for open distal tibial fractures: a comprehensive assessment of clinical outcomes and financial implications.

BACKGROUND: Open distal tibial fractures pose significant challenges regarding treatment options and patient outcomes. This retrospective single-centre study aimed to compare the stability, clinical outcomes, complications, and financial implications of two surgical interventions, namely the external locking plate and the combined frame external fixator, to manage open distal tibial fractures. METHODS: Forty-four patients with distal open tibial (metaphyseal extraarticular) fractures treated between 2020 and 2022 were selected and formed into two main groups, Group A and Group B. Group A (19 patients) are patients that underwent treatment using the external locking plate technique, while Group B (25 patients) received the combined frame external fixator approach. Age, gender, inpatient stay, re-operation rates, complications, functional recovery (measured by the Johner-Wrush score), pain ratings (measured by the Visual Analogue Scale [VAS]), and cost analyses were evaluated for each group. Statistical analyses using SPSS were conducted to compare the outcomes between the two groups. RESULTS: The research found significant variations in clinical outcomes, complications, and cost consequences between Group A and Group B. Group A had fewer hospitalisation periods (23.687.74) than Group B (33.5619.47). Re-operation rates were also considerably lower in Group A (26.3%) than in Group B (48%), owing to a greater prevalence of pin-tract infections and subsequent pin loosening in the combination frame external fixator group. The estimated cost of both techniques was recorded and analysed with the locking average of 26,619.69 ± 9,602.352 and the combined frame average of 39,095.64 ± 20,070.077. CONCLUSION: This study suggests that although the two approaches effectively manage open distal tibia fractures, the locking compression plate approach (Group A) has an advantage in treating open distal tibia fractures. Shorter hospitalisation times, reduced re-operation rates, and fewer complications will benefit patients, healthcare systems, and budget allocation. Group A's functional recovery results demonstrate the locking plate technique's ability to improve recovery and patient quality of life. According to the cost analysis, the locking plate technique's economic viability and cost-effectiveness may optimise healthcare resources for open distal tibia fractures. These findings might improve patient outcomes and inform evidence-based orthopaedic surgery.

Operative and Nonoperative Treatment of Humeral Shaft Fractures: A Cost-Effectiveness Analysis.

BACKGROUND: Decision-making with regard to the treatment of humeral shaft fractures remains under debate. The cost-effectiveness of these treatment options has yet to be established. This study aims to compare the cost-effectiveness of operative treatment with that of nonoperative treatment of humeral shaft fractures. METHODS: We developed a decision tree for treatment options. Surgical costs included the ambulatory surgical fee, physician fee, anesthesia fee, and, in the sensitivity analysis, lost wages during recovery. We used the Current Procedural Terminology codes from the American Board of Orthopaedic Surgery to determine physician fees via the U.S. Centers for Medicare & Medicaid Services database. The anesthesia fee was obtained from the national conversion factor and mean operative time for included procedures. We obtained data on mean wages from the U.S. Bureau of Labor and data on weeks missed from a similar study. We reported functional data via the Disabilities of the Arm, Shoulder and Hand (DASH) scores obtained from existing literature. We used rollback analysis and Monte Carlo simulation to determine the cost-effectiveness of each treatment option, presented in dollars per meaningful change in DASH score, utilizing a $50,000 willingness-to-pay (WTP) threshold. RESULTS: The cost per meaningful change in DASH score for operative treatment was $18,857.97 at the 6-month follow-up and $25,756.36 at the 1-year follow-up, by Monte Carlo simulation. Wage loss-inclusive models revealed values that fall even farther below the WTP threshold, making operative management the more cost-effective treatment option compared with nonoperative treatment in both settings. With an upward variation of the nonoperative union rate to 84.17% in the wage-exclusive model and 89.43% in the wage-inclusive model, nonoperative treatment instead became more cost-effective. CONCLUSIONS: Operative management was cost-effective at both 6 months and 1 year, compared with nonoperative treatment, in both models. Operative treatment was found to be even more cost-effective with loss of wages considered, suggesting that an earlier return to baseline function and, thus, return to work are important considerations in making operative treatment the more cost-effective option.

Clinical trial of a low-cost external fixator for global surgery use.

PURPOSE: A low-cost modular external fixator for the lower limb has been developed for global surgery use. The purpose of this study is to assess outcome measures in the first clinical use of the device. METHODS: A prospective cohort study was conducted with patients recruited in two trauma hospitals. Initial clinical procedure data were collected, and patients were followed up every two weeks until 12 weeks or definitive fixation. Follow-up assessed infection, stability, and radiographic outcomes. In addition, patient-reported outcomes and surgeons' feedback on device usability were collected by questionnaires. RESULTS: The external fixator was used on 17 patients. Ten were mono-lateral, five were joint spanning, and two were delta configuration. One patient had a pin site infection at 12-week follow-up. All were stable when tested mechanically and using radiographic assessment, and 53% were converted to definitive fixation. CONCLUSION: The low-cost external fixator developed is appropriate for use in global surgery trauma centres with good clinical outcomes. PROSPECTIVE TRIAL REGISTRATION NUMBER AND DATE: SLCTR/2021/025 (06 Sep 2021).

Racial Disparities in the Operative Management of Orthopedic Trauma: A Systematic Review and Meta-Analysis.

OBJECTIVE: The objective of this study was to investigate if race is associated with the likelihood of operative management of acute fractures. METHODS: A systematic review of the literature was performed using the PubMed, EMBASE, and Cochrane databases to identify studies associated with social disparities and acute orthopedic trauma. Peer-reviewed studies commenting on social disparities and the decision to pursue operative or non-operative management of acute fractures were identified for detailed review. Study characteristics and odds ratios were extracted from each article. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed. A quality analysis of the data was also performed. RESULTS: In total, 13 studies were identified and 8 were included in the meta-analysis totaling 743,846 fractures. Hip, distal radius, pelvic, tibial plateau, clavicle, femoral neck, and femoral shaft fractures were represented in this patient population. The meta-analysis demonstrated that White race is associated with a higher likelihood of operative intervention compared to all other races pooled together (odds ratio, 1.31; 95% confidence interval 1.16 to 1.47; p < .0001) as well as Black race (odds ratio 1.39; 95% confidence interval 1.12 to 1.72; p = .0025). CONCLUSIONS: Non-White race and Black race are associated with a lower likelihood of receiving surgical management of acute orthopedic trauma. Surgeons and health systems should be aware of these inequities and consider strategies to mitigate bias and ensure all patients receive appropriate and timely care regardless of race.

Cost-utility analysis of surgical fixation with Kirschner wire versus casting after fracture of the distal radius : a health economic evaluation of the DRAFFT2 trial.

AIMS: The aim of this study was to compare the cost-effectiveness of surgical fixation with Kirschner (K-)wire ersus moulded casting after manipulation of a fracture of the distal radius in an operating theatre setting. METHODS: An economic evaluation was conducted based on data collected from the Distal Radius Acute Fracture Fixation Trial 2 (DRAFFT2) multicentre randomized controlled trial in the UK. Resource use was collected at three, six, and 12 months post-randomization using trial case report forms and participant-completed questionnaires. Cost-effectiveness was reported in terms of incremental cost per quality-adjusted life year (QALY) gained from an NHS and personal social services perspective. Sensitivity analyses were conducted to examine the robustness of cost-effectiveness estimates, and decision uncertainty was handled using confidence ellipses and cost-effectiveness acceptability curves. RESULTS: In the base case analysis, surgical fixation with K-wire was more expensive (£29.65 (95% confidence interval (CI) -94.85 to 154.15)) and generated lower QALYs (0.007 (95% CI -0.03 to 0.016)) than moulded casting, but this difference was not statistically significant. The probability of K-wire being cost-effective at a £20,000 per QALY cost-effectiveness threshold was 24%. The cost-effectiveness results remained robust in the sensitivity analyses. CONCLUSION: The findings suggest that surgical fixation with K-wire is unlikely to be a cost-effective alternative to a moulded cast in adults, following manipulation of a fracture of the distal radius in a theatre setting.Cite this article: Bone Joint J 2022;104-B(11):1225-1233.

Hastes telescópicas para correção de deformidades e prevenção de fraturas em crianças e adolescentes em fase de crescimento com osteogênese imperfeita / Telescopic rods for deformity correction and fracture prevention in growing children and adolescents with osteogenesis imperfecta

INTRODUÇÃO: A OI é uma doença genética caracterizada por fragilidade óssea e fraturas recorrentes por mínimo trauma, além de deformidades de ossos longos e, nos casos mais graves, consequente incapacidade funcional para deambulação. Além do tratamento medicamentoso para aumentar densidade mineral óssea, cirurgias ortopédicas com inserção de dispositivos intramedulares são indicadas para corrigir as deformidades e estabilizar as fraturas. Entre estes dispositivos implantáveis disponíveis estão: fios (Kirschner ou Steinmann) e hastes (flexíveis ou extensíveis). Com o objetivo de alinhar os ossos longos prevenindo e corrigindo curvaturas que propiciem fraturas, a escolha por haste extensível, também chamada telescópica, para criança ou adolescente ainda em fase de crescimento se justifica por sua capacidade de se estender, acompanhando o crescimento ósseo e, possivelmente, reduzindo o número de revisões cirúrgicas para substituição do implante. Contudo, apesar da evolução das hastes extensíveis ao longo dos anos, chegando ao atual modelo Fassier Duval (FD), complicações pós-operatórias podem ocorrer e demandar revisão cirúrgica, assim como ocorre com as hastes e os dispositivos não extensíveis. TECNOLOGIA: Hastes intramedulares telescópicas (extensíveis). PERGUNTA: O uso de hastes intramedulares telescópicas (extensíveis, tipo Fassier Duval) é seguro e eficaz para correção de deformidades ósseas, redução das incidências de fraturas, revisões e complicações cirúrgicas, além de incremento dos resultados de

Cost Reduction for Knee-Spanning External Fixation in the Staged Treatment of Tibial Plateau Fractures: A Practical Intervention.

OBJECTIVE: To determine whether an educational intervention affects surgeon implant decision making measured by total implant costs for temporizing a knee-spanning external fixation construct. DESIGN: A total of 24 cases were prospectively collected after an educational intervention and matched to 24 cases before intervention using Schatzker classification and by surgeon. SETTING: A single Level 1 trauma center. PATIENTS/PARTICIPANTS: Forty-eight patients with Schatzker II-VI tibial plateau fractures. INTERVENTION: Education session to create transparency with component pricing and to provide 3 clinical cases of Orthopaedic Trauma Association/AO 41-C3 (Schatzker VI) with accompanying images and fixator construct costs. Total implant costs displayed in the session ranged from $2354 to $11,696. OUTCOME MEASUREMENT: External fixator construct cost. RESULTS: The mean cost of constructs in the postintervention group was $4550.20 [95% confidence interval (CI) $3945.60-$5154.00], which was significantly different compared with the preintervention group cost of $6046.75 (95% CI = $5309.54-$6783.97, P = 0.003). After 1 year, the total implant costs of external fixation constructs were reduced by an average of almost $1500 per patient. CONCLUSION: An educational intervention created a reduction in the average total implant construction costs for temporary knee-spanning external fixation in the treatment of tibial plateau fractures. Surgical implant selection and cost variance remain an ideal area to improve value for patients and hospitals. Empowering surgeons with knowledge regarding implant prices is a critical part of working toward the cost reductions of external fixation constructs.

External Fixation Characteristics Drive Cost of Care for High-Energy Tibial Plateau Fractures.

OBJECTIVE: To determine the total cost for a 30-day episode of care for high-energy tibial plateau fractures and the aspects of care associated with total cost. DESIGN: Time-driven activity-based costing analysis. SETTING: One Level 1 adult trauma center. PATIENTS: One hundred twenty-one patients with isolated, bicondylar tibial plateau fractures undergoing staged treatment were reviewed. PRIMARY OUTCOME: Total cost. RESULTS: A total of 85 patients were included and most sustained Schatzker VI fractures (n = 66, 77%). All patients were treated with biplanar external fixation before definitive fixation. A total of 26 patients (31%) were discharged to skilled nursing facilities, and 37 patients (43%) were not discharged between procedures. Total cost for a 30-day episode of care was $22,113 ± 4056. External fixation components ($5952, 26.9%), length of hospital stay ($5606, 25.4%), discharge to skilled nursing facility (SNF) ($3061, 13.8%), and definitive fixation implants ($2968, 13.4%) contributed to the total cost. The following were associated with total cost: patient discharged to SNFs (P < 0.001), patient remaining inpatient after external fixation (P < 0.001), days of admission for open reduction internal fixation (ORIF) (P = 0.005), days spent with external fixation (P < 0.001), days in a SNF after ORIF (P < 0.001), and external fixation component cost (P < 0.001). CONCLUSIONS: External fixation component selection is the largest contributor to cost of a 30-day episode of care for high-energy bicondylar tibial plateau fractures. Reduction in cost variability may be possible through thoughtful use of external fixation components and care pathways. LEVEL OF EVIDENCE: Economic analyses Level IV.

The Impact of the COVID-19 2020 Pandemic on Hospital Length of Stay Following Fragility Hip Fracture Surgery.

BACKGROUND: Hip fractures in elderly patients are a major cause of morbidity and mortality. Variability in length of hospital stay (LOS) was evident in this population. The coronavirus disease-2019 (COVID-19) pandemic led to prompt discharge of effected patients in order to reduce contagion risk. LOS and discharge destination in COVID-19 negative patients has not been studied. OBJECTIVES: To evaluate the LOS and discharge destination during the COVID-19 outbreak and compare it with a similar cohort in preceding years. METHODS: A retrospective study was conducted comparing a total of 182 consecutive fragility hip fracture patients operated on during the first COVID-19 outbreak to patients operated on in 2 preceding years. Data regarding demographic, co-morbidities, surgical management, hospitalization, as well as surgical and medical complications were retrieved from electronic charts. RESULTS: During the pandemic 67 fragility hip fracture patients were admitted (COVID group); 55 and 60 patients were admitted during the same time periods in 2017 and 2018, respectively (control groups). All groups were of similar age and gender. Patients in the COVID group had significantly shorter LOS (7.2 ± 3.3 vs. 8.9 ± 4.9 days, P = 0.008) and waiting time for a rehabilitation facility (7.2 ± 3.1 vs. 9.3 ± 4.9 days, P = 0.003), but greater prevalence of delirium (17.9% vs. 7% of patients, P = 0.028). In hospital mortality did not differ among groups. CONCLUSIONS: LOS and time to rehabilitation were significantly shorter in the COVID group. Delirium was more common in this group, possibly due to negative effects of social distancing.

Cost-effectiveness of surgery versus cast immobilization for adults with a bicortical fracture of the scaphoid waist : an economic evaluation of the SWIFFT trial.

AIMS: The aim of the Scaphoid Waist Internal Fixation for Fractures Trial (SWIFFT) was to determine the optimal treatment for adults with a bicortical undisplaced or minimally displaced fracture of the waist of the scaphoid, comparing early surgical fixation with initial cast immobilization, with immediate fixation being offered to patients with nonunion. METHODS: A cost-effectiveness analysis was conducted to assess the relative merits of these forms of treatment. The differences in costs to the healthcare system and quality-adjusted life years (QALYs) of the patients over the one-year follow-up of the trial in the two treatment arms were estimated using regression analysis. RESULTS: Our base case analysis found that patients randomized to early surgical fixation had statistically significantly higher mean costs to the NHS of £1,295 more than for the cast immobilization arm (p < 0.001), primarily due to the cost of surgery. They also had a marginally better quality of life, over the period, of 0.0158 QALYs; however, this was not statistically significant (p = 0.379). The mean combined cost per additional QALY was £81,962, well above the accepted threshold for cost-effectiveness used in the UK and internationally. The probability of early surgery being cost-effective in this setting was only 5.6%. CONCLUSION: Consistent with the clinical findings of SWIFFT, these results indicate that initial cast immobilization of minimally displaced scaphoid fractures, with immediate fixation only offered to patients with nonunion, is the optimal form of treatment, resulting in comparable outcomes with less cost to the healthcare system.

Spinopelvic Dissociation: Assessment, Reduction Strategies, and Fixation Techniques.

Spinopelvic dissociation is a rare injury associated with 2% to 3% of transverse sacral fractures and 3% of sacral fractures associated with pelvic ring injuries. When spinopelvic dissociation is expediently identified and treated appropriately, patient outcomes can be maximized, highlighting the importance of early diagnosis and treatment. Because of its rarity and complexity, there remains a paucity of high-level evidence-based guidance on treating this complex issue. No consensus exists on fixation techniques or reduction maneuvers to achieve stability, allowing for early functional rehabilitation. The purpose of this article is to review the current body of literature to better understand this injury pattern to help establish a treatment algorithm that appropriately guides the treating surgeons in the surgical planning and perioperative care of these patients.

Volar locking plate versus external fixation for unstable dorsally displaced distal radius fractures-A 3-year cost-utility analysis.

AIM: To investigate the cost-effectiveness of Volar Locking Plate (VLP) compared to External Fixation (EF) for unstable dorsally displaced distal radius fractures in a 3-year perspective. METHODS: During 2009-2013, patients aged 50-74 years with an unstable dorsally displaced distal radius fracture were randomised to VLP or EF. Primary outcome was the incremental cost-effectiveness ratio (ICER) for VLP compared with EF. Data regarding health effects (Quality-adjusted life years, QALYs) was prospectively collected during the trial period until 3 years after surgery. Cost data was collected retrospectively for the same time period and included direct and indirect costs (production loss). RESULTS: One hundred and thirteen patients (VLP n = 58, EF n = 55) had complete data until 3 years and were used in the analysis. At one year, the VLP group had a mean incremental cost of 878 euros and a gain of 0.020 QALYs compared with the EF group, rendering an ICER of 43 900 euros per QALY. At three years, the VLP group had a mean incremental cost of 1 082 euros and a negative incremental effect of -0.005 QALYs compared to the EF group, which means that VLP was dominated by EF. The probability that VLP was cost-effective compared to EF at three years, was lower than 50% independent of the willingness to pay per QALY. CONCLUSION: Three years after distal radius fracture surgery, VLP fixation resulted in higher costs and a smaller effect in QALYs compared to EF. Our results indicate that it is uncertain if VLP is a cost-effective treatment of unstable distal radius fractures compared to EF.

Cost-Effectiveness of Volar Locking Plate Compared with Augmented External Fixation for Displaced Intra-Articular Wrist Fractures.

BACKGROUND: The purpose of the present study was to estimate the cost-effectiveness of treating displaced, intra-articular distal radial fractures with volar locking plate fixation compared with augmented external fixation. METHODS: A cost-utility analysis was conducted alongside a randomized, clinical trial comparing 2 surgical interventions for intra-articular distal radial fractures. One hundred and sixty-six patients were allocated to either volar locking plate fixation (84 patients) or external fixation (82 patients) and were followed for 2 years. Health-related quality of life was assessed with the EuroQol-5 Dimensions and was used to calculate patients' quality-adjusted life-years (QALYs). Resource use was identified prospectively at the patient level at all follow-up intervals. Costs were estimated with use of both a health-care perspective and a societal perspective. Results were expressed in incremental cost-effectiveness ratios, and uncertainty was assessed with use of bootstrapping methods. RESULTS: The average QALY value was equivalent between the groups (1.70463 for the volar locking plate group and 1.70726 for the external fixation group, yielding a nonsignificant difference of -0.00263 QALY). Health-care costs were equal between the groups, with a nonsignificant difference of &OV0556;52 (p = 0.8) in favor of external fixation. However, the external fixation group had a higher loss of productivity due to absence from work (5.5 weeks in the volar locking plate group compared with 9.2 weeks for the external fixation group; p = 0.02). Consequently, the societal costs were higher for the external fixation group compared with the volar locking plate group (&OV0556;18,037 compared with &OV0556;12,567, representing a difference of &OV0556;5,470; p = 0.04) in favor of the volar locking plate group. Uncertainty analyses showed that there is indifference regarding which method to recommend from a health-care perspective, with volar locking plate treatment and external fixation having a 47% and 53% likelihood of being cost-effective, respectively. From the societal perspective, volar locking plate treatment had a 90% likelihood of being cost-effective. CONCLUSIONS: External fixation was less cost-effective than volar locking plate treatment for distal radial fractures from a societal perspective, primarily because patients managed with external fixation had a longer absence from work.

Biomechanical study of a low-cost external fixator for diaphyseal fractures of long bones.

BACKGROUND: External fixation improves open fracture management in emerging countries. However, sophisticated models are often expensive and unavailable. We assessed the biomechanical properties of a low-cost external fixation system in comparison with the Hoffmann® 3 system, as a reference. METHODS: Transversal, oblique, and comminuted fractures were created in the diaphysis of tibia sawbones. Six external fixators were tested in three modes of loading-axial compression, medio-lateral (ML) bending, and torsion-in order to determine construction stiffness. The fixator construct implies two uniplanar (UUEF1, UUEF2) depending the pin-rods fixation system and two biplanar (UBEF1, UBEF2) designs based on different bar to bar connections. The designed low-cost fixators were compared to a Hoffmann® 3 fixator single rod (H3-SR) and double rod (H3-DR). Twenty-seven constructs were stabilized with UUEF1, UUEF2, and H3-SR (nine constructs each). Nine constructs were stabilized with UBEF1, UBEF2, and H3-DR (three constructs each). RESULTS: UUEF2 was significantly stiffer than H3-SR (p < 0.001) in axial compression for oblique fractures and UUEF1 was significantly stiffer than H3-SR (p = 0.009) in ML bending for transversal fractures. Both UUEFs were significantly stiffer than H3-SR in axial compression and torsion (p < 0.05), and inferior to H3-SR in ML bending, for comminuted fractures. In the same fracture pattern, UBEFs were significantly stiffer than H3-DR (p = 0.001) in axial compression and torsion, while only UBEF1 was significantly stiffer than H3-DR in ML bending (p = 0.013). CONCLUSIONS: The results demonstrated that the stiffness of the UUEF and UBEF device compares to the reference fixator and may be helpful in maintaining fracture reduction. Fatigue testing and clinical assessment must be conducted to ensure that the objective of bone healing is achievable with such low-cost devices.

Current opinion in the assessment and management of ballistic trauma to the craniomaxillofacial region.

PURPOSE OF REVIEW: Ballistic trauma represents a small proportion of injuries to the craniomaxillofacial (CMF) region, even in societies where the availability of firearms is more prevalent. The aim of this article is to review current opinion in the assessment and management of ballistic injuries sequentially from primary survey to definitive reconstruction. RECENT FINDINGS: For mandibular fractures because of ballistic trauma, load-bearing fixation remains the mainstay in the treatment. The use of load sharing fixation is rarely advised, even if the fracture pattern radiologically appears to fulfil the traditional indications for its use. Clinicians must be aware of specific situations in early internal fixation is contraindicated, particularly in those unstable patients requiring short damage control surgical procedures, avulsive soft and hard tissue defects and those injuries at increased risk of infection. SUMMARY: Staged surgery for complex injuries is increasingly becoming accepted, by which injuries are temporarily stabilized by means of maxillary--mandibular fixation (MMF) or an external fixation. Patients are subsequently repeat CT-scanned, and definitive internal fixation performed a few days later. Increased access to virtual surgical planning (VSP) and three-dimensional plates has revolutionized fracture reconstruction.

An Assessment of Normal Tibiofibular Anatomy on Lateral Fluoroscopy.

BACKGROUND: Intraoperative identification of syndesmotic malreduction during ankle fracture fixation can be challenging. Prior studies describe the normal tibiofibular relationship on anteroposterior and mortise views to aid assessment, but the normal anatomic variation on the lateral view has not been well defined. The aim of this study was to describe the normal anatomy of the lateral radiographic view of the ankle, focusing on the relative position of the fibula and tibial plafond. METHODS: We retrospectively identified consecutive adults undergoing ankle fracture open reduction internal fixation in 2011-2018. Two independent observers assessed the tibiofibular relationship on perfect lateral images of the uninjured side. Measurements were made in pixels, converted into millimeters using published parameters, and averaged for analysis. Reliability was calculated using Pearson correlation coefficients. RESULTS: Of 751 cases of adult ankle fracture fixation identified, 50 patients had perfect lateral images of the contralateral side. In 11 patients (22%), the posterior border of the fibula intersected precisely at the posterior edge of the tibial plafond. Ten patients (20%) had anterior intersections, whereas 29 (58%) had posterior intersections. The intersection was within ±2 mm of the plafond edge in 27 patients (54%). Intrarater reliability was 0.86 and 0.93. Interrater reliability was 0.88. CONCLUSION: In most ankles, the posterior border of the fibula intersects the posterior extent of the tibial plafond within 2 mm. If more than 2 mm away, one should query malreduction, especially if anterior. This method of intraoperative assessment may decrease the occurrence of syndesmotic malreduction. LEVEL OF EVIDENCE: Level III, comparative series.

The Global Burden of Surgical Management of Osteoporotic Fractures.

Osteoporosis is an epidemic in the developed world. Fracture is a major burden associated with osteoporosis. Surgical management is recommended for particular anatomical areas, whilst other fracture patterns have a less defined and controversial role for surgery. This review aims to highlight increase in the global burden of osteoporosis and subsequent fragility fractures. As health and life expectancy improves, osteoporotic fracture fixation will constitute a significant physical and economic burden. The surgical management of osteoporotic fractures involves awareness on all levels from government to the individual, from primary prevention of fracture to surgical aftercare in the community.

In the cost-conscious era: Ilizarov circular frame or uniplanar external fixator for management of complex open tibia shaft fracture, retrospective cohort study from a level-1 trauma center.

OBJECTIVE: External fixation is the most commonly used method for temporary management of open fractures of the Tibial shaft followed by internal fixation. This can also be used as a definitive method of fixation. Ilizarov is more superior and can be the primary and definite option where expertise is available. This study was conducted todetermine the outcome of open tibia shaft fracture treated with either Ilizarov or AO External Fixator. METHODS: Anon-commercial retrospective cohort was conducted at Aga Khan University Hospital Karachi on patients operated for isolated open tibia fractures Gustillo type III (A, B, C) stabilized with external fixation either circular or uniplanar external fixator. These two groups were compared in terms of fracture pattern, healing and complications. For fracture healing, Radiographic union score (RUST) for tibial fractures were used. RESULTS: A total of 93 patients were included in the study. Mean age 36.7 +/- 17.3 years comprising 83 males and 10 females. Circular Fixator was used for 46 whereas 47 were treated with uni-planar fixator. Mean new injury severity score was 21 ± 3.4 for circular fixator group and 26 ± 7 in uniplanar fixator group. Mean time fur fracture healing was 6±1months in circular fixator group and 9 months in Uniplanar Fixator group. Mean RUST score for circular fixator was 9.5±1.2.and of uniplanar it was 7.3±1.0. CONCLUSIONS: Circular fixator works as a single stage procedure with acceptable outcomes for Gustilo grade III open tibial shaft fractures as compared to uniplanar external fixator.

Assessment of neovascularization during bone healing using contrast-enhanced ultrasonography in a canine tibial osteotomy model: a preliminary study.

Blood perfusion of skeletal muscle and callus was evaluated using contrast-enhanced ultrasonography (CEUS) in a canine osteotomy model to determine the applicability of CEUS in the assessment of neovascularization during fracture healing and to compare the vascular signals on CEUS between external skeletal fixation and cast-applied dogs. In 6 Beagle dogs, a simple transverse osteotomy was performed at the left tibial shaft and external skeletal fixation (n = 3) or a cast (n = 3) was applied. Radiography, power Doppler ultrasonography (power Doppler), and CEUS were performed until complete union was achieved. On CEUS, vascular changes were quantitatively evaluated by measuring peak intensity (PI) and time to PI in the soft tissue and callus and by counting the vascular signals. Vascular signals from the soft tissue were detected on power Doppler and CEUS on day 2. Significantly more vascular signals were detected by CEUS than by power Doppler. On CEUS, PI in the surrounding soft tissue was markedly increased after the fracture line appeared indistinctively changed on radiography in all dogs. In the cast-applied dogs, vascular signals from the periosteal and endosteal callus were detected on CEUS before mineralized callus was observed on radiography. CEUS was useful in assessing the vascularity of soft tissue and callus, particularly in indirect fracture healing, and provided indications of a normally healing fracture.

Significant Improvement in the Value of Surgical Treatment of Tibial Plateau Fractures Through Surgeon Practice Standardization.

INTRODUCTION: It is unclear whether cost-based decisions to improve the value of surgical care (quality:cost ratio) affect patient outcomes. Our hypothesis was that surgeon-directed reductions in surgical costs for tibial plateau fracture fixation would result in similar patient outcomes, thus improving treatment value. METHODS: This was a prospective observational study with retrospective control data. Surgically treated tibial plateau fractures from 2013 to October 2014 served as a control (group 1). Material costs for each case were calculated. Practices were modified to remove allegedly unnecessary costs. Next, cost data were collected on similar patients from November 2014 through 2015 (group 2). Costs were compared between groups, analyzing partial articular and complete articular fractures separately. Minimum follow-up (f/u) was 1-year. Outcomes data collected include Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) and pain interference domains, Western Ontario and McMaster Universities Osteoarthritis Index, visual analog pain scale, infection, nonunion, unplanned return to surgery, demographics, injury characteristics, and comorbidities. RESULTS: Group 1 included 57 partial articular fractures and 57 complete articular fractures. Group 2 included 37 partial articular fractures and 32 complete articular fractures. Median cost of partial articular fractures decreased from $1,706 to $1,447 (P = 0.025), and median cost of complete articular fractures decreased from $2,681 to $2,220 (P = 0.003). Group 1 had 55 patients who consented to clinical f/u, and group 2 had 39. Median PROMIS PF score was 40 for group 1 and was 43 for group 2 (P = 0.23). There were no significant differences between the groups for any clinical outcomes, demographics, injury characteristics, or comorbidities. Median f/u in group 1 was 31 months compared with 15 months in group 2 (P < 0.0001). DISCUSSION: We have demonstrated that surgeons can improve value of surgical care by reducing surgical costs while maintaining clinical outcomes.
