RESUMO
INTRODUCTION: Elastic stable intramedullary nailing (ESIN) is a well-defined and appropriate treatment of choice for long bone fractures. Despite its benefits, the risk of cancer from imaging devices is of particular concern for younger adults. So, this survey was conducted to estimate the doses administered to patients undergoing ESIN of long bone fractures utilizing a 2-dimensional (2D) C-arm fluoroscopy machine during surgery, as well as the carcinogenic risk associated with the use of the machine. METHODS: This study was conducted on 147 patients who required ESIN for long-bone fractures. Patients' demographic data, surgical data and imaging information were collected. For each patient, the organ doses and the effective doses were computed with the Monte Carlo PCXMC 2.0 simulation software. The cancer risk models proposed in the Biological Effects of Ionizing Radiation VII (BEIR VII) Phase 2 report were used to evaluate the risk of exposure-induced cancer death (REID) values. RESULTS: For all patients, the highest organ dose was delivered to the gonads. The mean effective dose was 0.026 ± 0.015 mSv and 1.3E-04 ± 1E-04 mSv for ESIN of femur and tibia fractures, respectively. Males had a mean REID of 1 per million, while females had a mean REID of 0.19 per million. The younger males had considerably higher REID values. The effective dose was significantly correlated with age, gender, and irradiation time. CONCLUSION: Low levels of effective doses and cancer risks associated with the utilization of the fluoroscopy machine in current practice were found in ESIN treatment of long-bone fractures. IMPLICATIONS FOR PRACTICE: This outcome will help to raise surgeons' awareness of radiation risks and encourage them to initiate measures to keep radiation dose and exposure time as low as reasonably achievable.

OBJECTIVES: To determine the accuracy of the intermalleolar method, an intraoperative fluoroscopic method for assessing tibial rotation in patients undergoing intramedullary nail fixation for tibial shaft fractures, by comparing it with the gold standard computed tomography (CT). DESIGN: Prospective cohort study. SETTING: Academic Level 1 trauma center. PATIENT SELECTION CRITERIA: Consecutive patients, aged 18 years and older, with unilateral tibial shaft fractures who underwent intramedullary fixation from September 2021 to January 2023. OUTCOME MEASURES AND COMPARISONS: Intraoperatively, tibial rotation measurements were obtained using the intermalleolar method on both the uninjured and injured limbs. Postoperatively, patients underwent bilateral low-dose lower extremity rotational CT scans. CT measurements were made by 4 blinded observers. Mean absolute rotational differences and standard errors were calculated to compare the injured and uninjured limbs. Subgroup analysis was performed assessing accuracy relating to injured versus uninjured limbs, body mass index, OTA/AO fracture pattern, tibial and fibular fracture location, and distal articular fracture extension requiring fixation. RESULTS: Of the 20 tibia fractures, the mean patient age was 43.4 years. The intermalleolar method had a mean absolute rotational difference of 5.1 degrees (standard error 0.6, range 0-13.7) compared with CT. Sixty percent (24/40) of the measurements were within 5 degrees, 90% (36/40) of the measurements were within 10 degrees, and 100% (40/40) were within 15 degrees of the CT. No patients were revised for malrotation postoperatively. CONCLUSIONS: The intermalleolar method is accurate and consistently provides intraoperative tibial rotation measurements within 10 degrees of the mean CT measurement for adult patients undergoing intramedullary nail fixation for unilateral tibial shaft fractures. This method may be employed in the operating room to accurately quantify tibial rotation and assist with intraoperative rotational corrections. LEVEL OF EVIDENCE: Diagnostic Level II.

INTRODUCTION: Financial toxicity is highly prevalent in patients after an orthopaedic injury. However, little is known regarding the conditions that promote and protect against this financial distress. Our objective was to understand the factors that cause and protect against financial toxicity after a lower extremity fracture. METHODS: A qualitative study was conducted using semi-structured interviews with 20 patients 3 months after surgical treatment of a lower extremity fracture. The interviews were audio-recorded, transcribed verbatim, and analyzed using thematic analysis to identify themes and subthemes. Data saturation occurred after 15 interviews. The percentage of patients who described the identified themes are reported. RESULTS: A total of 20 patients (median age, 44 years [IQR, 38 to 58]; 60% male) participated in the study. The most common injury was a distal tibia fracture (n = 8; 40%). Eleven themes that promoted financial distress were identified, the most common being work effects (n = 14; 70%) and emotional health (n = 12; 60%). Over half (n = 11; 55%) of participants described financial toxicity arising from an inability to access social welfare programs. Seven themes that protected against financial distress were also identified, including insurance (n = 17; 85%) and support from friends and family (n = 17; 85%). Over half (n = 13; 65%) of the participants discussed the support they received from their healthcare team, which encompassed expectation setting and connections to financial aid and other services. Employment protection and workplace flexibility were additional protective themes. CONCLUSION: This qualitative study of orthopaedic trauma patients found work and emotional health-related factors to be primary drivers of financial toxicity after injury. Insurance and support from friends and family were the most frequently reported protective factors. Many participants described the pivotal role of the healthcare team in establishing recovery expectations and facilitating access to social welfare programs.

INTRODUCTION: Lactic acid is well studied in the trauma population and is frequently used as a laboratory indicator that correlates with resuscitation status and has thus been associated with patient outcomes. There is limited literature that assesses the association of initial lactic acid with post-operative morbidity and hospitalization costs in the orthopedic literature. The purpose of this study was to assess the association of lactic acid levels and alcohol levels post-operative morbidity, length of stay and admission costs in a cohort of operative lower extremity long bone fractures, and to compare these effects in the ballistic and blunt trauma sub-population. METHODS: Patients presenting as trauma activations who underwent tibial and/or femoral fixation at a single institution from May 2018 to August 2020 were divided based on initial lactate level into normal, (< 2.5) intermediate (2.5-4.0), and high (> 4.0). Mechanism of trauma (blunt vs. ballistic) was also stratified for analysis. Data on other injuries, surgical timing, level of care, direct hospitalization costs, length of stay, and discharge disposition were collected from the electronic medical record. The primary outcome assessed was post-operative morbidity defined as in-hospital mortality or unanticipated escalation of care. Secondary outcomes included hospital costs, lengths of stay, and discharge disposition. Data were analyzed using ANOVA and multivariate regression. RESULTS: A total of 401 patients met inclusions criteria. Average age was 34.1 ± 13.0 years old, with patients remaining hospitalized for 8.8 ± 9.5 days, and 35.2% requiring ICU care during their hospitalization. Patients in the ballistic cohort were younger, had fewer other injuries and had higher lactate levels (4.0 ± 2.4) than in the blunt trauma cohort (3.4 ± 1.9) (p = 0.004). On multivariate regression, higher lactate was associated with post-operative morbidity (p = 0.015), as was age (p < 0.001) and BMI (p = 0.033). ISS, ballistic versus blunt injury mechanism, and other included laboratory markers were not. Lactate was also associated with longer lengths of stay, and higher associated direct hospitalization cost (p < 0.001) and lower rates of home disposition (p = 0.008). CONCLUSION: High initial lactate levels are independently associated with post-operative morbidity as well as higher direct hospitalization costs and longer lengths of stay in orthopedic trauma patients who underwent fixation for fractures of the lower extremity long bones. Ballistic trauma patients had significantly higher lactate levels compared to the blunt cohort, and lactate was not independently associated with increased rates of post-operative morbidity in the ballistic cohort alone. LEVEL OF EVIDENCE: III.

BACKGROUND: Distal femur fractures are known to have challenging nonunion rates. Despite various available treatment methods aimed to improve union, optimal interventions are yet to be determined. Importantly, there remains no standard agreement on what defines radiographic union. Although various proposed criteria of defining radiographic union exist in the literature, there is no clear consensus on which criteria provide the most precise measurement. The use of inconsistent measures of fracture healing between studies can be problematic and limits their generalizability. Therefore, this systematic review aims to identify how fracture union is defined based on radiographic parameters for surgically treated distal femur fractures in current literature. METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, Medline, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science Core Collection databases were searched from inception to October 2022. Studies that addressed surgically treated distal femur fractures with reported radiographic union assessment were included. Outcomes extracted included radiographic definition of union; any testing of validity, reliability, or responsiveness; reported union rate; reported time to fracture union; and any functional outcomes correlated with radiographic union. RESULTS: Sixty articles with 3,050 operatively treated distal femur fractures were included. Operative interventions included lateral locked plate (42 studies), intramedullary nail (15 studies), dynamic condylar screw or blade plate (7 studies), dual plate or plate and nail construct (5 studies), distal anterior-posterior/posterior-anterior screws (1 study), and external fixation with a circular frame (1 study). The range of mean follow-up time reported was 4.3 to 44 months. The most common definitions of fracture union included "bridging or callus formation across 3 of 4 cortices" in 26 (43%) studies, "bony bridging of cortices" in 21 (35%) studies, and "complete bridging of cortices" in 9 (15%) studies. Two studies included additional assessment of radiographic union using the Radiographic Union Scale in Tibial fracture (RUST) or modified Radiographic Union Scale in Tibial fracture (mRUST) scores. One study included description of validity, and the other study included reliability testing. The reported mean union rate of distal femur fractures was 89% (range 58%-100%). The mean time to fracture union was documented in 49 studies and found to be 18 weeks (range 12-36 weeks) in 2,441 cases. No studies reported correlations between functional outcomes and radiographic parameters. CONCLUSION: The current literature evaluating surgically treated distal femur fractures lacks consistent definition of radiographic fracture union, and the appropriate time point to make this judgement is unclear. To advance surgical optimization, it is necessary that future research uses validated, reliable, and continuous measures of radiographic bone healing and correlation with functional outcomes.

The purpose of this study is to determine the financial practicality for the use of nasal povidone-iodine (NP-I) in the preoperative holding area in attempt to decrease the rate of infection that is associated with operative fixation of closed pilon fractures. Institutional costs for treating postoperative infection following a closed pilon fracture, along with costs associated with preoperative NP-I use, were obtained. A break-even equation was used to analyze these costs to determine if the use of NP-I would decrease the current infection rate (17%) enough to be financially beneficial for routine use preoperatively. The total cost of treating a postoperative infection was found to be $18,912, with the cost of NP-I being $30 per patient dose. Considering a 17% infection rate and utilizing the break-even equation, NP-I was found to be economically viable if it decreased the current infection rate by 0.0016% (Number Needed to Treat = 63,051.7). This break-even model suggests that the use of NP-I in the preoperative holding area is financially beneficial for decreasing the rate of infection associated with the treatment of closed pilon fractures.

The objective of the study was to evaluate the long-term strength and gait outcomes after intramedullary nailing of isolated tibial diaphyseal fractures. This retrospective cohort study was conducted at an academic Level I trauma center. Fifteen participants with isolated tibial diaphyseal fractures (OTA/AO 42) at least 2 years postoperative from intramedullary nailing (IMN) provided informed consent. The average age was 40 ± 14 (range, 24-69); there were nine men and six women. Knee flexion-extension strength data were collected. Temporal-spatial, kinematic, and kinetic gait parameters were measured and compared to historic control data. Participants completed the SF-36 and shortened musculoskeletal function assessment questionnaires. The mean length of follow-up between surgery and gait analysis was 6 ± 2 years. The fractured limb demonstrated deficits in quadriceps strength between 9.8% and 23.4% compared to the unaffected limb. Temporal-spatial parameters revealed slower walking speed, shorter stride length, decreased cadence, and shorter single-limb support time in the fractured limb. Altered kinematic and kinetic findings included a knee extension shift during stance, with an increased knee flexor moment demand and decreased total knee power during loading and midstance. These findings represent deficits in concentric and eccentric knee extensor activity. Additionally, the fractured limb demonstrated decreased ankle dorsiflexion during stance and diminished ankle push-off power. Long-term outcomes after IMN of tibial diaphyseal fractures demonstrate decreased quadriceps strength and altered gait parameters that may have implications to the high incidence of knee and ankle pain in the fractured limb.

Managing tibial fractures requires substantial health resources, which costs the health system. This study aimed to describe the costs of photobiomodulation (PBM) with LEDs in the healing process of soft tissue lesions associated with tibial fracture compared to a placebo. Economic analysis was performed based on a randomized controlled clinical trial, with a simulation of the cost-effectiveness and incremental cost model. Adults (n = 27) hospitalized with tibia fracture awaiting definitive surgery were randomized into two distinct groups: the PBM Group (n = 13) and the Control Group with simulated phototherapy (n = 14). To simulate the cost-effectiveness and incremental cost model, the outcome was the evolution of wound resolution by the BATES-JENSEN scale and time of wound resolution in days. The total cost of treatment for the Control group was R$21,164.56, and a difference of R$7,527.10 more was observed when compared to the treatment of the PBM group. The proposed intervention did not present incremental cost since the difference in the costs to reduce measures between the groups was smaller for the PBM group. When analyzing the ICER (Incremental cost-effectiveness ratio), it would be possible to save R$3,500.98 with PBM and decrease by 2.15 points in the daily average on the BATES-JENSEN scale. It is concluded, therefore, that PBM can be a supportive therapy of clinical and economic interest in a hospital setting.

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.

PURPOSE: Patients with tibial plateau fractures (TPF) are at risk of long-term hampered bipedal locomotion. A retrospective single-center study using patient-related outcome measures and a sophisticated assessment of walking abilities was conducted. METHODS: Adults receiving surgical treatment of an isolated TPF between January 2012 and December 2016 received the KOOS questionnaire together with the invitation for an extensive follow-up examination on the clinical outcome including standardized assessment of the walking abilities (loadsol® system). Outcome was assessed relative to the severity of the injury or time to follow-up. Fractures were classified according to AO/OTA and Luo, respectively. RESULTS: 58 out of 132 eligible patients filled in the questionnaire and participated at a median follow-up of 3.05 years after injury. For the categories "pain", "mobility", and "daily life activities", all patients were rather satisfied and this was virtually not related to the time between fracture and assessment. Relevant limitations were reported for "sports and recreational activities" and "quality of life". Loading of the previously fractured leg was most evidently changed on stairs and outdoor walking. Outcome was not related to either fracture type severity or time from injury. CONCLUSION: Outcome after an isolated TPF is neither related to fracture type, severity of the fracture nor time from injury. Simple gait analysis techniques relying on different tasks appear to yield a more sophisticated image on functional deficits after TPF than classical exam of ground-level walking and correlate quite well with validated patient-related outcome measures as the KOOS.

BACKGROUND: Few contemporary US-based long bone non-union analyses have recently been published. Our study was designed to provide a current understanding of non-union risks and costs, from the payers' perspective. METHODS: The Merative™ MarketScan® Commercial Claims and Encounters database was used. Patients with surgically treated long bone (femur, tibia, or humerus) fractures in the inpatient setting, from Q4 2015 to most recent, were identified. Exclusion criteria included polytrauma and amputation at index. The primary outcome was a diagnosis of non-union in the 12 and 24 months post-index. Additional outcomes included concurrent infection, reoperation, and total healthcare costs. Age, gender, comorbidities, fracture characteristics, and severity were identified for all patients. Descriptive analyses were performed. Crude and adjusted rates of non-union (using Poisson regressions with log link) were calculated. Marginal incremental cost of care associated with non-union and infected non-union and reoperation were estimated using a generalized linear model with log link and gamma distribution. RESULTS: A total of 12,770, 13,504, and 4,805 patients with femoral, tibial, or humeral surgically treated fractures were identified, 74-89% were displaced, and 18-27% were comminuted. Two-year rates of non-union reached 8.5% (8.0%-9.1%), 9.1% (8.6%-9.7%), and 7.2% (6.4%-8.1%) in the femoral, tibial, and humeral fracture cohorts, respectively. Shaft fractures were at increased risk of non-union versus fractures in other sites (risk ratio (RR) in shaft fractures of the femur: 2.36 (1.81-3.04); tibia: 1.95 (1.47-2.57); humerus: 2.02 (1.42-2.87)). Fractures with severe soft tissue trauma (open vs. closed, Gustilo III vs. Gustilo I-II) were also at increased risk for non-union (RR for Gustilo III fracture (vs. closed) for femur: R = 1.96 (1.45-2.58), for tibia: 3.33 (2.85-3.87), RR for open (vs. closed) for humerus: 1.74 (1.30-2.32)). For all fractures, younger patients had a reduced risk of non-union compared to older patients. For tibial fractures, increasing comorbidity (Elixhauser Index 5 or greater) was associated with an increased risk of non-union. The two-year marginal cost of non-union ranged from $33K-$45K. Non-union reoperation added $16K-$34K in incremental costs. Concurrent infection further increased costs by $46K-$86K. CONCLUSIONS: Non-union affects 7-10% of surgically treated long bone fracture cases. Shaft and complex fractures were at increased risk for non-union.

OBJECTIVES: To determine the impact of acute compartment syndrome (ACS) and identify cost drivers of 1-year total treatment costs for operative tibial plateau fractures. DESIGN: Retrospective review. SETTING: Level 1 trauma center. PATIENTS: 337 patients with tibial plateau fractures, 24 of which were complicated by ACS. OUTCOMES: The primary outcome was total treatment cost over the first year for operatively treated tibial plateau fractures. The secondary objective was to use regression analysis to identify significant cost drivers. RESULTS: The diagnosis of ACS was associated with 2.85 times higher total treatment cost ( P < 0.001). ACS demonstrated increased total treatment cost when controlling for polytrauma ( P < 0.001) and postoperative infection ( P < 0.001). Regression analysis identified 5 variables significantly associated with total cost of care: body mass index, injury severity score, ACS, staged external fixation, and locking fixation ( P < 0.001; R 2 = 0.57). The diagnosis of ACS had the largest impact on total cost with a 3.5× greater impact on cost compared with the next highest variable, staged external fixation. CONCLUSIONS: Tibial plateau fractures complicated by ACS are associated with 2.85 times higher treatment costs over a 1-year period. There were 5 significant variables identified by regression analysis with ACS having the highest impact on total treatment. Together, these 5 factors account for 57% of treatment cost variability.

OBJECTIVES: To determine whether an acute fixation protocol for high-energy tibial pilon fractures increases the rate of wound complications. DESIGN: Retrospective comparative study. SETTING: Urban level 1 trauma center. PATIENTS/PARTICIPANTS: One hundred forty-seven patients with OTA/AO 43B and 43C high-energy tibial pilon fractures treated with open reduction and internal fixation (ORIF). INTERVENTION: Acute (<48 hours) versus delayed ORIF protocols. MAIN OUTCOME MEASUREMENT: Wound complications, reoperations, time to fixation, operative costs, and hospital length of stay (LOS). Patients were compared by protocol, regardless of ORIF timing, for an intention-to-treat analysis. RESULTS: Thirty-five and 112 high-energy pilon fractures were treated under the acute and delayed ORIF protocols, respectively. In the acute ORIF protocol group, 82.9% of patients received acute ORIF versus 15.2% of patients in the standard delayed protocol group. The 2 groups had no observed difference (OD) in the rate of wound complications (OD -5.7%, confidence interval (95% CI) -16.1% to 7.8%; P = 0.56) or reoperations (OD -3.9%, 95% CI, -14.1% to 9.4%; P = 0.76). The acute ORIF protocol group had a shorter LOS (OD -2.0, 95% CI, -4.0 to 0.0; P = 0.02) and lower operative costs (OD $-2709.27, 95% CI, -3582.02 to -1601.16; P < 0.01). On multivariate analysis, wound complications were associated with open fractures (odds ratio 3.36, 95% CI, 1.06-10.69; P = 0.04) and an American Society of Anesthesiologists score >2 (odds ratio 3.68, 95% CI, 1.07-12.67; P = 0.04). CONCLUSION: This study suggests that an acute fixation protocol for high-energy pilon fractures decreases time to definitive fixation, lowers operative costs, and shortens hospital LOS without affecting wound complications or reoperations. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVES: To investigate whether an acute fixation protocol for high-energy tibial plateau fractures increases the rate of wound complications. DESIGN: Retrospective comparative study. SETTING: Urban level 1 trauma center. PATIENTS/PARTICIPANTS: One hundred thirty-four patients with high-energy tibial plateau fractures (OTA/AO 41B/C [Schatzker VI/V/VI]) treated with open reduction and internal fixation (ORIF). INTERVENTION: Utilization of an acute ORIF (<48 hours) versus delayed ORIF protocol. MAIN OUTCOME MEASURE: Primary outcomes: wound complications (wound dehiscence/necrosis, superficial/deep infections) and reoperations. Secondary outcomes: total operative costs and hospital length of stay. RESULTS: Overall, 83.9% (26/31) of patients received definitive fixation within 48 hours under the acute ORIF protocol versus 18.4% (19/103) of patients treated under the standard delayed protocol with no observed differences in the rate of wound complications (proportional difference (PD) -4.6%, confidence interval (CI) -17.2% to 11.3%; P = 0.78) or reoperations (PD 2.0%, CI, 13.0% to 12.5%; P = 1.00). The acute ORIF protocol lowered operative costs (median difference (MD) $-2.563.00, CI, 3021.00 to -1661.00; P < 0.001) and hospital length of stay (MD 4.0 days, CI, 6.0-1.0; P = 0.001). On multivariate analysis, wound complications were associated with increasing age (odds ratio (OR) 1.05, CI, 1.01-1.10; P = 0.01) and tobacco use (OR 3.75, CI, 1.19-11.82; P = 0.02). CONCLUSION: An acute ORIF protocol for high-energy tibial plateau fractures decreased time to fixation and lowered operative costs without increasing the risk of wound complications or reoperations. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVES: To evaluate the presence of financial distress and identify risk factors for financial toxicity in patients after tibial shaft fracture. DESIGN: A cross-sectional analysis. SETTING: Level I trauma center. PATIENTS: All patients within 4 years after tibial shaft fracture (open, closed, or fracture that required flap reconstruction). INTERVENTION: Injury-related financial distress. MAIN OUTCOME MEASUREMENTS: Financial distress related to the injury, as reported by the patient in a binary question. Financial toxicity using the LIMB-Q, scored from 0 to 100, with higher scores indicating more financial toxicity. RESULTS: Data were collected from 142 patients after tibial shaft fracture [44% closed (n = 62), 41% open (n = 58), and 15% flap (n = 22)]. The mean age was 44 years (SD 17), 61% were men, and the mean time from injury was 15 months. Financial distress was reported by 64% of patients (95% confidence interval, 56% to 72%). Financial toxicity did not differ by fracture severity ( P = 0.12). Medical complications were associated with a 14-point increase in financial toxicity ( P = 0.04). Age older than 65 years (-15 points, P = 0.03) and incomes of $70,000 or more ($70,000-$99,999, -15 points, P = 0.02; >$100,000, -19 points, P < 0.01) protected against financial toxicity. CONCLUSION: We observed financial distress levels more than twice the proportion observed after cancer. Medical complications, lower incomes, and younger age were associated with increased financial toxicity. LEVEL OF EVIDENCE: Prognostic Level IV.

PURPOSE: The cost implications of limb reconstruction techniques have not been adequately investigated. Aim of this pilot study was to compare the direct medical cost of tibial bone defects managed with distraction osteogenesis-Ilizarov method (ILF), or with Masquelet technique (MIF). METHODS: Data of 20 random patients treated in a single centre were analysed. Inclusion criteria included acute tibial defects, or post-debridement of nonunions with complete follow-up and successful union. The endpoint of clinical efficacy was the time-to-defect union. Comparisons were made between equally sized subgroups (ILF vs. MIF). RESULTS: The average defect length was 5.6 cm (2.6-9.6 cm). The overall cost of 20 cases reached £452,974 (mean £22,339, range £13,459-£36,274). Statistically significant differences favoring the MIF were found regarding the average time-to-union; number of surgeries, of admissions and follow-up visits, as well as the mean intraoperative cost (£8857 vs. £14,087). These differences lead to significant differences of the mean cost of the overall treatment (MIF £18,131 vs. ILF £26,126). Power analysis based on these data indicated that 35 patients on each group would allow detection of a 25% difference, with an alpha value of 0.05 and probability (power) of 0.9. CONCLUSIONS: The results and analysis presented highlight factors affecting the high financial burden, even in a best-case scenario, this type of surgery entails. Larger pivotal studies should follow to improve the cost efficiency of clinical practice.

OBJECTIVE: To assess the impact of severe obesity on 30-day adverse event rates, hospital length of stay (LOS), readmissions, and projected costs after operative fixation of tibia and femur fractures. METHODS: An analysis of the American College of Surgeons National Surgical Quality Improvement Project database from 2012 to 2019 of isolated femoral shaft and tibial shaft fracture fixation cases was conducted. Adverse events, LOS, readmission rates, and operative time were queried for severe obesity, defined as body mass index greater than 40, compared with other patients. Student t tests were used to assess continuous variables. Fisher exact test and odds ratios were used for categorical variables. A cost-analysis was also performed to quantify the effect of severe obesity on projected health care expenditures. RESULTS: A total of 10,436 patients were included with 7.0% of patients categorized as severely obese. Severely obese patients had higher infectious complication rates (9.0% vs. 6.7%, P = 0.013, OR 1.36, 95% CI 1.04-1.78), readmission rates (7.9% vs. 5.6%, P-value = 0.008, OR 1.44, 95% CI 1.08-1.91), longer LOS (5.8 days SD ±10.2 vs. 5.0 days SD ±7.9 days, P-value = 0.008), and longer operative times (mean 115 minutes ± 56 minutes SD vs. 103 minutes SD ±54 minutes, P-value = <0.001). Severe obesity resulted in an estimated $4258.07 additional health care expenditures per patient compared with nonobese patients. This amounted to a projected added total expenditure of $3.09 million USD in the overall cohort. CONCLUSION: Severe obesity is associated with significantly worse 30-day outcomes and higher readmission rates for patients undergoing operative fixation of tibial shaft and femoral shaft fractures. Health policy considerations should be made to incentivize care for this patient population, particularly in trauma where modification of risk factors before surgery is often not feasible. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

The distal tibia bone quality is of paramount importance for ankle fractures, total ankle implants, ankle fusions, and osteotomy procedures. Despite this fact relatively little is known regarding the overall bone quality for this section of the tibia. Previous literature suggest that there is a statistically significant decrease in bone mineral density within the distal 5% to 10% segment of the tibia medullary canal. This segment of medullary bone is considerable in size and thus valuable for fixation constructs as it is oftentimes utilized for medial malleolar fractures, distal tibia fractures, total ankle replacements, ankle fusions, and other procedures. This study assessed bone attenuation between the distal 5% and 10% mark of the tibia in 1% slices via Hounsfield unit measurements on CT scans based on previously established correlation between Hounsfield units and bone mineral density found on DEXA scans. One hundred five distal tibia segments were assessed with an average interval in percentile slices of 3.8 mm. As expected there was a gradual decrease in bone attenuation noted with each proximal percentile segment. There exists a statistically significant difference in bone attenuation among males versus females as well as those older than 60 years versus younger than 60 years. The findings suggest fixation constructs in the tibia medullary canal may find limited benefit proximal from 7% segment in females ≥60, or 26.1 mm from tibial plafond. Fixation constructs in tibia medullary canal may find limited benefit proximal from 8% segment in males <60, or 32.3 mm from tibial plafond.

OBJECTIVE: To analyse the results after tibial plateau fractures with a focus on socioeconomic consequences. METHODS: On the basis of the data from the rehabilitation documentation of the German Statutory Accident Insurance (DGUV) on tibial plateau fractures (Code 83), a retrospective anonymised evaluation of the injuries which occurred in 2010 and 2016 was carried out. The registry data allowed subdivision into 3 groups: Medial, lateral and bicondylar tibial plateau fractures. The data have been analysed with regard to the following parameters: age, gender, treatment, time of return to work (AU), costs per case, total costs, workers compensation (MdE) and total payments. RESULTS: The analysis includes 1046 isolated tibial plateau fractures for 2010 and 1072 for 2016. In 2016, 798 fractures could be assigned to the medial, lateral or bicondylar fracture groups. In 551 cases, both condyles were involved. In another 221 cases, the lateral plateau and in 26 the medial plateau was injured. There were 476 (59.7%) men and 322 (40.4%) women. The mean age was 43.4 (SD ± 16.7) years with a peak of 180 cases in the 55-60 year subgroup and 98 aged 15-20 years. The mean age of the cases with isolated lateral plateau involvement was 48.1 (SD ± 13.8) and was 47.5 (SD ± 16.6) in those with medial plateau fractures and 41.4 (SD ± 17.2) years in the subgroup with bicondylar patterns. The mean time of return to work was 39.4 (SD ± 25.3) weeks for the bicondylar tibial plateau fractures, 28.1 (SD ± 27.2) weeks for the medial and 24.5 (SD ± 22.8) weeks for the lateral groups. For the 2016 group, the mean costs were 5212 for outpatient, 10358 for inpatient and 7622 for rehab costs per case (total costs over three years of 4247443 for outpatient and 7506508 for acute inpatient treatment). The highest costs per case were caused by the inpatient acute treatment of bicondylar tibial plateau fractures, at a mean of 22292 . 17.6% of the 2016 casualty group resulted in compensation of at least 20%. The treatment costs for the 2010 group over 9 years (2010-2019) amounted to 4190855 for outpatient treatments and 9565313 for inpatient treatments. In addition, compensations of 8632448 and lump-sum payments of 483289 were paid from 2010 to 2019. Over a period of 9 years, 456 (66%) of 692 patients needed another in patient follow-up treatment. A total of 51% (n = 353) needed these treatments within the first year. CONCLUSION: Tibial plateau fractures, in particular bicondylar tibial plateau fractures, show long-term, cost-intensive healing processes with reduced occupational capacity. Tibial plateau fractures are of economic importance in the statutory accident insurance in the long term. Preventive measures, optimal care and rehabilitation are therefore essential, together with innovative research to improve clinical outcomes.

High-energy orthopedic injuries cause severe damage to soft tissues and are prone to infection and healing complications, making them a challenge to manage. Further research is facilitated by a clinically relevant animal model with commensurate fracture severity and soft-tissue damage, allowing evaluation of novel treatment options and techniques. Here we report a reproducible, robust, and clinically relevant animal model of high-energy trauma with extensive soft-tissue damage, based on compressed air-driven membrane rupture as the blast wave source. As proof-of-principle showing the reproducibility of the injury, we evaluate changes in tissue and bone perfusion for a range of different tibia fracture severities, using dynamic contrast-enhanced fluorescence imaging and microcomputed tomography. We demonstrate that fluorescence tracer temporal profiles for skin, femoral vein, fractured bone, and paw reflect the increasing impact of more powerful blasts causing a range of Gustilo grade I-III injuries. The maximum fluorescence intensity of distal tibial bone following 0.1 mg/kg intravenous indocyanine green injection decreased by 35% (p < 0.01), 75% (p < 0.001), and 87% (p < 0.001), following grade I, II, and III injuries, respectively, compared to uninjured bone. Other kinetic parameters of bone and soft tissue perfusion extracted from series of fluorescence images for each animal also showed an association with severity of trauma. In addition, the time-intensity profile of fluorescence showed marked differences in wash-in and wash-out patterns for different injury severities and anatomical locations. This reliable and realistic high-energy trauma model opens new research avenues to better understand infection and treatment strategies. Level of evidence: Level III; Case-control.
