Surgical management and outcomes following atypical subtrochanteric femoral fractures - results from a matched-pair analysis of the registry for geriatric trauma of the German Trauma Society.

BACKGROUND AND OBJECTIVES: The outcomes of patients with atypical subtrochanteric fractures (ASFs) remain unclear. Data from a large international geriatric trauma registry were analysed to examine the outcome of patients with ASFs compared to patients with typical osteoporotic subtrochanteric fractures (TSFs). MATERIALS AND METHODS: Data from the Registry for Geriatric Trauma of the German Trauma Society (Deutsche Gesellschaft für Unfallchirurgie [DGU]) (ATR-DGU) were analysed. All patients treated surgically for ASFs or TSFs were included in this analysis. Across both fracture types, a paired matching approach was conducted, where statistical twins were formed based on background characteristics sex, age, American Society of Anesthesiologists (ASA) score and walking ability. In-house mortality and mortality rates at the 120-day follow-up, as well as mobility at 7 and 120 days, the reoperation rate, hospital discharge management, the hospital readmission rate at the 120-day follow-up, health-related quality of life, type of surgical treatment and anti-osteoporotic therapy at 7 and 120 days, were assessed as outcome measures using a multivariate logistic regression analysis. RESULTS: Amongst the 1,800 included patients, 1,781 had TSFs and 19 had ASFs. Logistic regression analysis revealed that patients with ASFs were more often treated with closed intramedullary nailing (RR = 3.59, p < 0.001) and had a higher probability of vitamin D supplementation as osteoporosis therapy at 120 days (RR = 0.88, p < 0.002). Patients with ASFs were also more likely to live at home after surgery (RR = 1.43, p < 0.001), and they also tended to continue living at home more often than patients with TSFs (RR = 1.33, p < 0.001). Accordingly, patients with TSFs had a higher relative risk of losing their self-sufficient living status, as indicated by increased rates of patients living at home preoperatively and being discharged to nursing homes (RR = 0.19, p < 0.001) or other hospitals (RR = 0.00, p < 0.001) postoperatively. CONCLUSIONS: Surgical treatment of ASFs was marked by more frequent use of closed intramedullary fracture reduction. Furthermore, patients with ASFs were more likely to be discharged home and died significantly less often in the given timeframe. The rate of perioperative complications, as indicated by nonsignificant reoperation rates, as well as patient walking abilities during the follow-up period, remained unaffected.

Risk factors for mechanical failure of intertrochanteric fractures after fixation with proximal femoral nail antirotation (PFNA II): a study in a Southeast Asian population.

INTRODUCTION: Intertrochanteric hip fractures pose a significant health problem. The proximal femur nail anti-rotation (PFNA IIDePuySynthes) is the most commonly used implant for intramedullary nailing of unstable intertrochanteric fractures at our institution. We aim to identify the risk factors predisposing to mechanical failure of intertrochanteric hip fractures fixation with PFNAII in our Southeast Asian population. MATERIALS AND METHODS: We retrospectively reviewed 295 consecutive patients who underwent PFNA fixation for intertrochanteric fractures of the proximal femur between January 2014 and June 2018 at our institution. Exclusion criteria included a follow-up period of less than 4 months and patients with polytrauma. 204 patients were eligible for analysis, of which 22 had mechanical failure of PFNAII. We compared these patients with respect to their demographics, medical co-morbidities, quality of reduction according to the Baumgartner scale, calcar restoration, blade position according to Cleveland Zones, the stability of fracture according to OTA/AO classification, neck-shaft-angle, tip-apex distance, as well as neck of femur bone mineral density T-score. Patients were followed up for a minimum of 4 months and until fracture union or complication had occurred. Logistic regression analysis was performed to determine the odds ratio for mechanical failure for selected variables. RESULTS: Good quality of reduction reduced risk of mechanical failure whilst posterior blade position in lateral hip X-ray predicted it, with odds ratios of 0.147 (95% confidence interval, 0.030-0.733; p = 0.019) and12.12 (95% confidence interval, 1.583-92.825; p = 0.016) respectively. On univariate analysis, the mechanical failure group were older, had poorer calcar restoration, more unstable fracture patterns, more varus neck-shaft angle, and trochanteric starting points that were lateral to or on the tip of the greater trochanter. However, these were not significant in multivariate analysis. Tip apex distance, the severity of osteoporosis, presence of diabetes, chronic kidney disease and serum vitamin D levels were not significant predictors of failure. CONCLUSIONS: To avoid mechanical failure, one should aim to achieve a good quality of reduction and centre blade position on lateral hip X-ray. Tip apex distance did not predict mechanical failure in our study.

Plate fixation versus intramedullary nailing of proximal humerus fractures: an ACS NSQIP-based comparative analysis over 8 years.

PURPOSE: The primary goal of this study was to compare the utilization of plate versus intramedullary nail (IMN) in the treatment of humerus fractures. Secondarily, we sought to examine whether any differences in demographics and clinical course of patients who receive a nail versus plate affect the procedure selection process. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database was queried for patients surgically treated for a humeral shaft fracture from the years 2007-2015, using current procedural terminology (CPT) code. Patients with overlapping procedures, nonunion, polytrauma, and malignancy were excluded. The Charlson Comorbidity Index (CCI) was calculated to compare preoperative comorbidities. A two-sample Wilcoxon rank-sum (Mann-Whitney U) test was used to compare numerical values, whereas the Fisher exact and Chi-squared analyses were performed to compare categorical variables. A p value < 0.05 was considered significant. Preoperative variables with a p value < 0.05 and a clinical prevalence > 1%, indicating statistical and clinical significance, were included in a logistic regression for multivariate analysis to identify any independent predictors for procedure selection (IMN versus PF) based on preoperative patient characteristics. RESULTS: During the study period plate fixation increased from 7 cases per year to 272 cases per year, while IMN increased from 8 cases per year to 80 cases per year. IMNs were mostly in older patients (63.85 vs 56.19 years, p < 0.001), and patients with a higher Charlson Comorbidity Index (CCI) (4.64 vs 2.79, p < 0.001). IMN was associated with shorter operation times (104 min vs 128 min, p < 0.001) and longer lengths of hospital stay (3.43d vs 2.78d, p < 0.001). No significant differences in overall complication rates were seen between patients who received IMN versus PF. However, the postoperative mortality rate was higher in patients who received IMN compared to PF (2.19% vs 0.40%, p < 0.01). Based on the regression analysis, patient age was the only independent patient factor demonstrated to predict the utilization of IMN over PF in older patients with humeral shaft fractures p = 0.043). CONCLUSION: According to this NSQIP-based analysis, the rate of PF and IMN utilization increased in the treatment of humeral shaft fractures over a period of 8 years, but PF was performed at an overall a higher rate than IMN. Intramedullary nailing was preferred over PF in older patients with more comorbidities. The last possibly contributed to the higher 30-day mortality rate observed in patients who received IMN compared to PF. LEVEL OF EVIDENCE III: Retrospective comparative study.

Treatment and re-operation rates in one thousand and three hundred tibial fractures from the Swedish Fracture Register.

PURPOSE: Approximately, 50 persons per 100,000 per year sustain a tibial fracture. There is, however, a lack of large cohort studies that describe the treatment and re-operation frequencies of tibial fractures. The aim of this study was to describe the treatment and re-operation rates of tibial fractures in all segments of the tibia. METHODS: Data related to all patients aged 16 and above treated for tibial fractures (ICD-10 S82.10-31) at Sahlgrenska University Hospital in 2011-2015 were extracted from the Swedish Fracture Register. To make sure all re-operations were included in the study, the operation planning system was checked for all patients included in the study. RESULTS: The study comprised 1371 tibial fractures - 712 proximal, 417 diaphyseal and 242 distal tibial fractures. Among the proximal and distal tibial fractures, plate fixation was the most commonly used surgical method, whereas among tibial shaft fractures, an intramedullary nail was the most commonly used surgical method. Almost 30% (29.8%) of all surgically treated tibial fractures underwent re-operation. Among proximal tibial fractures, 24.0% underwent re-operation; tibial shaft fractures 37.0% and distal tibial fractures 26.8%. Re-operations due to infection were more or less equally common in all segments (3.9-5.4%). CONCLUSION: This study describes the treatment and re-operation rates after tibial fractures in a cohort of 1371 tibial fractures at Sahlgrenska University Hospital during a period of 5 years. The study shows an overall re-operation rate of 29.8% for fractures in all segments of the tibia.

Exploring trends in admissions and treatment for ankle fractures: a longitudinal cohort study of routinely collected hospital data in England.

BACKGROUND: Evidence on the most effective and cost-effective management of ankle fractures is sparse but evolving. A recent large RCT in older patients with unstable fractures found that management with close-contact-casting was functionally equivalent and more cost-effective than internal fixation. We describe temporal and geographic variation in ankle fracture management and estimate the potential savings if close-contact-casting was used more often in older patients. METHODS: Patients admitted to hospital in England between 2007/08 and 2016/17 with an ankle fracture were identified using routine hospital episode statistics. We tested whether the use of internal fixation, and the proportion of internal fixations using intramedullary implants, changed over time. We estimated the potential annual cost savings if patients aged 60+ years were treated with close-contact-casting rather than internal fixation, in line with emerging evidence. RESULTS: Over the 10-year period, there were 223,465 hospital admissions with a primary ankle fracture diagnosis. The incidence (per 100,000) of internal fixation was fairly consistent over time in younger (33.2 in 2007/08, 30.9 in 2016/17) and older (36.5 in 2007/08, 37.4 in 2016/17) patients. The proportion of internal fixations which used intramedullary implants increased in both age groups (17.0-19.5% < 60 years; 15.2-17.4% 60+ years). In 2016/17, the cost of inpatient hospital care for ankle fractures in England was over £63.1million. If 50% of older patients who had an internal fixation instead had close-contact-casting, we estimate that approximately £1.56million could have been saved. CONCLUSIONS: Despite emerging evidence that non-surgical and surgical management achieve equivalent functional outcomes in older patients, the rate of surgical fixation has remained relatively stable over the decade. The health service could achieve substantial savings if a higher proportion of older patients were treated with close-contact-casting, in line with recent evidence.

Predictors of Open Reduction in Pediatric Femur Fractures Treated With Flexible Nails.

BACKGROUND: Closed reduction (CR) is sufficient to reduce the majority of femur fractures treated with flexible intramedullary nailing (FIN). No previous study has examined factors associated with failed CR of pediatric femoral shaft fractures treated with FIN. We sought to determine preoperative factors associated with failed CR. We hypothesized that fracture, patient, and surgeon characteristics would impact the need for open reduction (OR). METHODS: A retrospective review of children treated for femur fracture between 2012 and 2017 at a tertiary pediatric hospital was performed. Comparisons were made between 2 groups: FIN with CR group and FIN that required OR group. Demographic and baseline characteristics were compared between treatment groups using either χ tests or Fisher exact tests for categorical variables and general linear models for continuous variables. Odds ratios with 95% confidence intervals were calculated using univariate logistic regression tests. RESULTS: Of 449 consecutive pediatric femur fractures treated at our center, 85 children were treated with FIN and constituted the study cohort. CR failed in 14 patients (16.5%) necessitating OR of the fracture site. Significant differences between study groups were found in fracture location (P=0.018), the mechanism (P=0.003), and displacement on the anteroposterior radiograph (P=0.027). Surgical time was found to be longer in the OR group (P=0.010). We identified 3 preoperative predictors of OR for FIN including fractures caused by high energy mechanisms (odds ratio=7.5), distal third fractures (odds ratio=15.3), and fracture displacement on the anteroposterior view (odds ratio=1.06). Surgeon years in practice, patient weight, age, and time from injury to surgery were not associated with OR. CONCLUSIONS: This study presents 3 preoperative risk factors that predict the need for OR of femur fractures treated with FIN. Surgical time was longer in cases that required OR. Our findings suggest that surgeons should avoid lengthy attempts at CR and consider a lower threshold for OR of at-risk fractures or use another technique other than flexible nails. LEVEL OF EVIDENCE: Level III-prognostic.

Rates of Contralateral SCFE in the United States: Analysis of the Pediatric Health Information System.

BACKGROUND: Slipped capital femoral epiphysis (SCFE) is relatively common in pediatric patients. Subsequent contralateral SCFE is also common and rates of bilateral SCFE have been reported to range from 12% to 80% in the literature. The purpose of this study was to determine the rates of subsequent contralateral SCFE in patients who present with unilateral SCFE in the United States and determine risk factors for the development of subsequent contralateral SCFE. METHODS: The authors performed a retrospective study using data from the Pediatric Health Information System (PHIS). Patients who underwent in situ pinning of a unilateral SCFE between 2004 and 2016 were included in this study and followed prospectively to determine subsequent contralateral SCFE. They excluded patients who underwent bilateral pinning at index admission. Descriptive, univariate, and multivariate statistics were used to determine rates of subsequent contralateral SCFE and identify factors associated with contralateral SCFE. RESULTS: This study included 9755 patients who underwent in situ pinning for unilateral SCFE. The mean age at the time of index SCFE was 11.9 years (SD, 1.7) and ~62% of patients were male individuals. Subsequent contralateral SCFE occurred in 1077 (11%) patients at an average of 277 days (range, 7 to 1523 d) after the index procedure. Patients who developed a subsequent contralateral SCFE were younger at the time of index SCFE than patients who did not develop a contralateral SCFE (11.3 vs. 12 y old, P<0.01). In multivariate analysis, older children had a lower risk of subsequent contralateral SCFE (adjusted odds ratio, 0.8; 95% confidence interval, 0.77-0.83), and the odds of subsequent contralateral SCFE decreased by 20% with each increasing year in age. CONCLUSIONS: The rate of subsequent contralateral SCFE is ~11% in the United States, and younger patients are more likely to develop a contralateral SCFE than older patients. Prophylactic pinning should be considered in younger patients with unilateral SCFE, and patients should be followed until skeletal maturity to monitor for subsequent contralateral SCFE.

Intraoperative Issues and Clinical and Radiographic Outcomes of Femur Fractures Treated With Flexible Nails: A Comparison of Cases Utilizing Skeletal Traction and a Traction Table to Cases Using Manual Traction Only.

INTRODUCTION: The use of the orthopaedic traction table (OTT) during elastic stable intramedullary nailing (ESIN) in the management of displaced diaphyseal femur fractures (DFFs) is still debated. In most centers, children with displaced DFF are treated using an OTT. In some other institutions, however, fracture reduction and stabilization by ESIN are performed on a radiolucent table without an OTT. The aim of this study was to evaluate the clinical and radiologic outcome of children with displaced DFF managed by ESIN with and without the use of an OTT. METHODS: Charts and radiographs were retrospectively reviewed for all pediatric patients sustaining DFF managed by ESIN from 2011 to 2017 at 2 different institutions. In all, 69 consecutive children with displaced DFF were recorded, of whom 35 underwent operative treatment by ESIN with the use of an OTT with skeletal traction (Group A), and 34 by ESIN without OTT (Group B). The titanium elastic nails outcome measure scale score and Beaty radiologic criteria were used to evaluate the results. RESULTS: Average patient age at time of injury was 9 years (range, 5 to 13) and 10 years (range, 4 to 15) in Groups A and B, respectively. The mean follow-up was 54 months (range, 24 to 96). Overall, complications were observed in 6 patients (8.6%). Complication rate was higher among children managed without OTT (11.8%) than among children treated with OTT (2.5%); no complication related to pin insertion for skeletal traction was recorded. However, the number of patients with a poor outcome according to the titanium elastic nails outcome score was higher in Group A (20%) than in Group B (5.8%). Beaty radiologic criteria were comparable between the 2 groups. Mean length of surgery and mean cumulative time of radiation exposure during surgery were similar between the 2 groups. CONCLUSIONS: Overall, both techniques work equally well although patients treated by ESIN with the use of an OTT and skeletal traction tended to have a lower rate of complications and radiologic outcome was worse than for patients treated without using an OTT; however, no statistically significant difference was found.Despite their limitations, the results of this study suggest that displaced DFF can be safely managed by ESIN with or without the use of intraoperative OTT and skeletal traction, according to the surgeon's preference. Further studies are now needed to consolidate these conclusions and clarify the role of the OTT. LEVEL OF EVIDENCE: Level III.

Outcome at 1 year in patients with femoral shaft fractures treated with intramedullary nailing or skeletal traction in a low-income country: a prospective observational study of 187 patients in Malawi.

Background and purpose - Intramedullary nailing (IMN) is underutilized in low-income countries (LICs) where skeletal traction (ST) remains the standard of care for femoral shaft fractures. This prospective study compared patient-reported quality of life and functional status after femoral shaft fractures treated with IMN or ST in Malawi. Patients and methods - Adult patients with femoral shaft fractures managed by IMN or ST were enrolled prospectively from 6 hospitals. Quality of life and functional status were assessed using EQ-5D-3L, and the Short Musculoskeletal Function Assessment (SMFA) respectively. Patients were followed up at 6 weeks, 3, 6, and 12 months post-injury. Results - Of 248 patients enrolled (85 IMN, 163 ST), 187 (75%) completed 1-year follow-up (55 IMN, 132 ST). 1 of 55 IMN cases had nonunion compared with 40 of 132 ST cases that failed treatment and converted to IMN (p < 0.001). Quality of life and SMFA Functional Index Scores were better for IMN than ST at 6 weeks, 3 and 6 months, but not at 1 year. At 6 months, 24 of 51 patients in the ST group had returned to work, compared with 26 of 37 in the IMN group (p = 0.02). Interpretation - Treatment with IMN improved early quality of life and function and allowed patients to return to work earlier compared with treatment with ST. Approximately one-third of patients treated with ST failed treatment and were converted to IMN.

Cost-Effectiveness of Titanium Elastic Nail (TEN) in the Treatment of Forearm Fractures in Children.

Background and objectives: There are various methods in the management of forearm fractures in children. Elastic stable intramedullary nailing using Titanium Elastic Nail (TEN) is nowadays employed in diaphysis fractures of children, with clear benefits over other treatment options. However, in the case of TEN versus other treatment methods of forearm fractures in children, cost is an important issue. This report will focus on the cost assessment of using TEN versus other therapeutic means in the treatment of forearm fractures in children. Materials and Methods: We performed a retrospective longitudinal study of 173 consecutive patients with forearm fractures treated in a single institution during 2017. We calculated the cost for each patient by summing up direct costs plus indirect costs, calculated at an aggregate level. Hospital income data were extracted from the Diagnosis Related Groups database. Results: A total of 173 patients with forearm fractures were treated, 44 using TEN, 86 using K-wire, and 46 using closed reduction and cast. There were 66 radius fractures, 1 ulna fracture, and 106 that were both radius and ulna fractures. Mean treatment cost were $632.76 for TEN, $499.50 for K-wire, and $451.30 for closed reduction and cast. Costs for TEN were higher than for K-wire insertion (p = 0.00) and higher than closed reduction and cast ($182.42; p = 0.00). Reimbursement per patient was higher with TEN versus K-wire patients; $497.88 vs. $364.64 /patient (p = 0.00), and higher than for patients treated with closed reduction and cast (p = 0.00). Conclusions: The treatment of upper extremity fractures using TEN was more expensive than the other methods. In Romania, because the reimbursement for TEN is higher as well, there are no differences in the financial burden when treating forearm fractures with TEN versus K-wire. Non-surgical treatment has the lowest cost but also the lowest reimbursement.

Risk factors for nonunion after intramedullary nailing of subtrochanteric femoral fractures.

INTRODUCTION: Nonunion is a common complication after intramedullary nailing of subtrochanteric femoral fractures. A more detailed knowledge, particularly of avoidable risk factors for subtrochanteric fracture nonunion, is thus desired to develop strategies for reducing nonunion rates. The aim of the present study therefore was to analyse a wide range of parameters as potential risk factors for nonunion after intramedullary nailing of subtrochanteric fractures. MATERIALS AND METHODS: Seventy-four patients who sustained a subtrochanteric fracture and were treated by femoral intramedullary nailing at a single level 1 trauma centre within a 6-year period were included in this study. A total of 15 patient-related, fracture-related, surgery-related, mechanical and biological parameters were analysed as potential risk factors for nonunion. Furthermore, the accuracy of each of these parameters to predict nonunion was calculated. RESULTS: Nonunion occurred in 17 of 74 patients (23.0%). Of the 15 potential risk factors analysed, only 3 were found to have a significant effect on the nonunion rate (p < 0.05): postoperative varus malalignment, postoperative lack of medial cortical support and autodynamisation of the nail within the first 12 weeks post-surgery. Accuracy of each of these 3 parameters to predict nonunion was > 0.70. Furthermore, the nonunion rate significantly increased with the number of risk factors (no risk factor: 2.9%, one risk factor: 23.8%, two risk factors: 52.9%, and three risk factors: 100% [Chi-square test, p = 0.001)]. CONCLUSIONS: Our study indicates that intraoperative correction of varus malalignment and restoration of the medial cortical support are the most critical factors to prevent nonunion after intramedullary nailing of subtrochanteric femoral fractures. In addition, autodynamisation of the nail within the first 3 months post-surgery is a strong predictor for failure and should result in revision surgery.

Comparison of intraoperative radiation exposure with and without use of distal targeting device: a randomized control study.

INTRODUCTION: When locking intramedullary nails, inserting the distal interlocking screw accurately and quickly with less radiation exposure is very important. The purpose of this randomized control study was to compare radiation exposure and accuracy of distal locking screws between free-hand fluoroscopic guidance and the use of a distal targeting system (DTS). MATERIALS AND METHODS: Inclusion criteria of this study were patients older than 60 years who need an intramedullary nailing due to unstable intertrochanteric and subtrochanteric fracture. The primary outcome was the attempt numbers of image intensifier during the insertion of distal locking screws. Secondary outcomes were operative time and angles between distal locking screws and nail. RESULTS: A total of 36 patients participated in the study. Eighteen patients using free-hand fluoroscopic guidance were assigned to Group I while 18 patients using DTS were assigned to Group II. The number of attempts of image intensifier during distal screw insertion (57.3 ± 31.42 vs. 11.5 ± 7.41, p < 0.001), ratio of attempt number for distal screws to the total attempts (0.33 ± 0.21 vs. 0.12 ± 0.08, p = 0.001), the number of hand exposure to image intensifier directly (75.0 ± 29.55 vs. 13.5 ± 19.07, p < 0.001), and the time of radiation exposure during distal screws insertion (42.57 ± 2.42 s vs. 12.72 ± 8.10 s, p < 0.001) were significantly lower in Group II compared to those in Group I. And, operation time (96.3 min ± 18.94 vs. 76.1 min ± 14.10, p < 0.001) was also statistically significantly lower in Group II. Both distal locking screws were significantly closer to perpendicular direction to the nail in Group II. CONCLUSION: The attempt number of image intensifier during the insertion of two distal locking screws was significantly reduced with DTS compared with that with free hand fluoroscopic guidance. Angle between distal locking screws and nail was also more accurate using DTS.

The association between weight-bearing status and early complications in hip fractures.

BACKGROUND: Early mobilization and weight-bearing have been proposed to improve hip fracture outcomes. This study aimed to compare early postoperative complications and outcomes of patients who underwent weight-bearing as tolerated (WBAT) on postoperative day one (POD1) with those that did not on: (1) 30-day mortality; (2) 30-day postoperative major and minor complications; (3) length of stay (LOS); and (4) discharge disposition after hip fracture management. METHODS: The NSQIP database was used to identify 7947 hip fracture patients managed with a hemiarthroplasty and internal fixation, sliding hip screw, or cephalomedullary nail, for a total of 5845 patients were allowed to WBAT on POD1. They were compared to patients who were non-WBAT using adjusted multivariate regression models to evaluate the effect of WBAT status on the outcomes above. RESULTS: Among the cephalomedullary nail patients, WBAT on POD1 was associated with a decreased likelihood of mortality. In the cephalomedullary nail and sliding hip screw treatment groups, patients were less likely to experience major and minor complications if they were WBAT on POD1. WBAT patients had shorter LOS in the sliding hip screw and cephalomedullary nail treatment groups. Patients were less likely to be discharged to a non-home facility when WBAT on POD1 regardless of treatment. CONCLUSION: Early weight-bearing after surgical care of hip fracture seems to decrease morbidity and mortality; however, this effect is treatment dependent. These findings further support the need for early mobilization and rapid recovery programs in the care of hip fracture patients. LEVEL OF EVIDENCE: Level III.

Obesity's Influence on Operative Management of Pediatric Supracondylar Humerus Fractures.

BACKGROUND: As childhood obesity remains an ongoing issue for the United States there has been an increasing number of studies detailing its effect on fracture complexity, management, and outcomes. This study utilizes a national database to examine whether obese children with supracondylar humerus fractures are more likely to require open reduction and internal fixation than nonobese children. METHODS: The Healthcare Cost and Utilization Project Kid's Inpatient Database of 2003, 2006, 2009, 2012 were queried for pediatric supracondylar humerus fractures [International Classification of Disease (ICD-9), 812.41] between 2 and 12 years. Patients were separated into those undergoing closed reduction percutaneous pinning (CRPP), open reduction internal fixation (ORIF), or both. Obesity was determined by comorbidity and ICD-9 coding (ICD-9, 278.00, 278.01). Univariable and multivariable logistic regression models were utilized with P<0.05 considered significant. RESULTS: Between 2003 and 2012, 31,905 patients between the ages of 2 and 12 years sustained supracondylar humerus fractures. In total, 105 patients (0.3%) were obese. A majority of patients, 27,658 (86.7%), underwent CRPP. Odds for ORIF increased in association with age, obesity, white race, and private insurance. Significant association was found between age and obesity (P<0.05) in those undergoing ORIF. Obese children between 2 and 7 years of age had no difference in ORIF or CRPP compared with normal-weight children. Those between 8 and 12 years who were obese were significantly more likely to undergo ORIF (OR, 4.29; 95% confidence interval, 1.78-10.36). CONCLUSIONS: Supracondylar humerus fractures sustained in obese children between 8 and 12 years are over 4 times more likely to require ORIF compared with normal-weight children of the same age. Providers should identify and counsel older obese children and their families regarding the potential for increased difficulty in fracture management that may require open surgical intervention.

Treatment Modalities for Pathologic Fractures of the Proximal Femur Pertrochanteric Region: A Systematic Review and Meta-Analysis of Reoperation Rates.

BACKGROUND: The proximal femur represents the most common site of metastatic bone disease in the appendicular skeleton, and associated pathologic pertrochanteric femur fractures contribute to cancer-related morbidity and mortality. Controversy exists as to whether these injuries are best managed with intramedullary nailing (IMN) or with arthroplasty. METHODS: A systematic review of the literature was performed using a PubMed search following PRISMA guidelines to identify studies performed within the last 20 years regarding treatment of proximal femur metastatic lesions with either nailing or arthroplasty with a reported reoperation rate. Sixteen studies were selected for inclusion containing 1414 patients. Pooled estimates and 95% confidence intervals (CIs) for reoperation rates associated with IMN and endoprosthetic reconstruction (EPR) were separately calculated. RESULTS: The pooled estimate for reoperation for IMN was a median of 9% (95% CI, 5%-14%) and the pooled estimate for reoperation for EPR was a median of 7% (95% CI, 5%-11%). Significant heterogeneity was present in studies reporting on both treatment modalities: for IMN, I2 = 55%, and for EPR, I2 = 51%. CONCLUSION: This systematic literature review identified 16 eligible, nonrandomized, retrospective studies that reported on the results of surgical treatment for proximal femur metastatic disease. The pooled estimate of reoperation was similar between patients treated with IMN and EPR. Inconsistencies among follow-up and the study designs used limited evidence-based conclusions. As the oncologic care of patients with metastatic disease continues to evolve and improve, patient-specific needs must be carefully considered when selecting an optimal treatment strategy.

Tranexamic Acid in Pertrochanteric Femoral Fracture: Is it a Safe Drug or Not?

BACKGROUND: There is a high incidence of blood transfusion following hip fractures in elderly patients. AIM: The aim of this study is to evaluate the effectiveness and complications of use of tranexamic acid in proximal femur nailing surgery. MATERIALS AND METHODS: Our sample group consisted of 90 patients suffering from pertrochanteric fractures surgically treated with osteosynthesis with SupernailGT(LimaCorporate). The classification system AO/OTA was used to divide the fractures into 31A1 (n=45) and 31A2 (n=45). The patients were divided into two groups: 47 patients were administered 15 mg of tranexamic acid per kg (group A) and 43 patients were administered placebo (group B). Blood counts were monitored daily to evaluate the rate of anemia. As a safety criterion, we monitored the possible occurrence of vascular events, symptomatic or not, over the 8 weeks post-surgery. Markers predicting mortality and deep venous thrombosis (DVE) were also monitored (fibrinogen D-dimer). RESULTS: Blood loss occurring post-surgery can be influenced by numerous factors that are not linked to the use or non-use of tranexamic acid. While closely monitoring hemoglobin levels daily, we observed that 42% of the patients in group A required blood transfusion as opposed to 60% in group B. The results of the markers predicting mortality (alpha1-acid glycoprotein; albumin LDL) and those of DVE were not statistically significant between the two groups in this study (p>0.05). CONCLUSION: Based on this study, the use of tranexamic acid was statistically significant in reducing post-surgery blood loss.

Surgical outcomes of intramedullary nailing for diaphyseal atypical femur fractures: is it safe to modify a nail entry in bowed femur?

INTRODUCTION: The purpose of the study was to determine the surgical outcomes of intramedullary nailing in diaphyseal atypical femoral fractures (AFFs) and to evaluate the clinical outcomes of nail entry modification technique. MATERIALS AND METHODS: We retrospectively reviewed diaphyseal AFFs treated with IMN at nine institutions. In total, 82 patients were included. Surgical outcomes such as complication, union time, and femoral bowing were evaluated. We modified the nail entry of the straight nail from piriformis fossa to the tip of the greater trochanter in the bowed femur and compared the surgical outcomes between the original group and the modification group. RESULTS: The average union time was 20.1 weeks, and the union rate was 89.0%. The average union time was 13.1 weeks and 21 weeks in incomplete and complete AFFs, respectively. There was no nonunion in incomplete AFFs, but 13.8% in complete AFFs. Complete AFFs had 86.2% of union rate. There were 46 cases of group 1 with original entry point and 19 cases of group 2 with modified entry. In group 2, the union rate was similar to group 1 and union time was shorter. CONCLUSION: Changing the entry point laterally allowed the nail to be accommodated in bowed femurs, decreasing the risk of deformity and improving healing time. In severely varus femur, the lateral entry of the straight nail can be a useful technique.

Subtrochanteric fractures in elderly people treated with intramedullary fixation: quality of life and complications following open reduction and cerclage wiring versus closed reduction.

INTRODUCTION: Subtrochanteric fractures are more difficult to treat than other proximal femoral fractures. The aim of this study was to report the outcomes for patients with subtrochanteric fractures treated using a cephalomedullary nail following open reduction and cerclage wiring versus closed reduction alone, regarding health-related quality of life (HRQoL) and social function. MATERIALS AND METHODS: We performed a prospective cohort study including patients aged 60 years or older suffering fragility subtrochanteric fractures of the femur treated with cephalomedullary nails, with a minimum 2-year follow-up. We defined two treatment groups: one treated with closed reduction manoeuvres (60 patients), and another treated with open reduction and cerclage wiring (30 patients). The outcomes were mortality, orthopaedic complications (reoperation and no-union), social function (Jensen Index), and HRQoL (EQ-5D index score). RESULTS: There were no differences regarding sex, age, side affected, type of implant, anaesthetic risk, 1-year mortality, and orthopaedic complications. Surgical time was longer in the cerclage wire group, but length of stay was 2 days shorter for the cerclage group and reduction was better. Patients treated with cerclage wiring had significantly better EQ-ED at 12 months (0.66 ± 0.22 points vs. 0.78 ± 0.15 points); and social status at 12 and 18 months (2.77 ± 1.00 points vs. 2.10 ± 1.22 points). CONCLUSIONS: Better reduction is achieved when using cerclage wires for fragility subtrochanteric fractures. These fractures had a negative effect on quality of life and social function, but better outcomes were observed in the cerclage group.

[Elderly trauma patients with proximal femur fractures : Statistical evaluation of regular process data from a trauma center for the elderly]. / Alterstraumatologische Patienten mit proximaler Femurfraktur : Auswertung von Routinedaten eines Alterstraumazentrums.

BACKGROUND/AIMS: Proximal femoral fractures are one of the most frequently occurring injuries among elderly people. High rates of inpatient treatment indicate the importance of optimized clinical care. OBJECTIVES: Based on selected outcome parameters in elderly trauma patients with proximal femoral fractures, the current situation of medical care in a trauma center for geriatric patients is presented. METHODS: For a descriptive evaluation of outcome parameters, 250 patients aged 70 years and older have been included. A clinical register of a trauma center for the elderly served as the database. RESULTS: The average length of stay was approximately 25 days. Sixty-seven percent of the patients underwent surgical treatment within 24 h of admission to the hospital. More than half of the patients were taking anticoagulant drugs. Around 18 % of patients presented with one or more complications. Mortality rate was 5.2 %. Thirty-two percent of those patients who had been living at home before admission had been discharged to a nursing home. DISCUSSION AND CONCLUSIONS: Analyzing the data of a trauma registry enables critical reflection upon the clinical outcome of interdisciplinary treatment procedures. The low rate of mortality may be a result of the geriatric co-treatment, starting right from admission. It remains unclear whether the influence of preoperative interdisciplinary treatment outweighs the effect of a timely surgical procedure.

Quality of life following hip fractures: results from the Norwegian hip fracture register.

BACKGROUND: Patient-reported health-related quality of life is an important outcome measure when assessing the quality of hip fracture surgery. The frequently used EQ-5D index score has unfortunately important limitations. One alternative can be to assess the distribution of each of the five dimensions of the patients' descriptive health profile. The objective of this paper was to investigate health-related quality of life (HRQoL) after hip fractures. METHODS: Data from hip fracture operations from 2005 through 2012 were obtained from The Norwegian Hip Fracture Register. Patient reported HRQoL, (EQ-5D-3L) was collected from patients preoperatively and at four and twelve months postoperatively n = 10325. At each follow-up the distribution of the EQ-5D-3L and mean pain VAS was calculated. RESULTS: Generally, a higher proportion of patients reported problems in all 5 dimensions of the EQ-5D-3L at all follow-ups compared to preoperative. Also a high proportion of patients with no preoperative problems reported problems after surgery; At 4 and 12 months follow-ups 71 % and 58 % of the patients reported walking problems, and 65 % and 59 % of the patients reported pain respectively. Patients with femoral neck fractures and the youngest patients (age < 70 years) reported least problems both preoperatively and at all follow-ups. CONCLUSIONS: A hip fracture has a dramatic impact on the patients' HRQoL, and the deterioration in HRQoL sustained also one year after the fracture. Separate use of the descriptive profile of the EQ-5D is informative when assessing quality of life after hip fracture surgery.
