RESUMO
Case: A 62-year-old woman presenting with ankle pain was initially treated for a non-displaced fracture. Persistent pain despite months of conservative management for her presumed injury prompted repeat radiographs which demonstrated the progression of a lytic lesion and led to an orthopedic oncology referral. Following a complete work-up, including biopsy and staging, she was diagnosed with colorectal carcinoma metastatic to the distal fibula. Conclusion: Secondary tumors of the fibula are uncommon but an important diagnosis to consider for intractable lower extremity pain especially in patients with history of malignancy or lack of age-appropriate cancer screening.
RESUMO
BACKGROUND: Implants are a significant contributor to health care costs. We hypothesized that extra-articular fracture patterns would have a lower implant charge than intra-articular fractures and aimed to determine risk factors for increased cost. METHODS: In total, 163 patients undergoing outpatient distal radius fracture fixation at 2 hospitals were retrospectively reviewed stratified by Current Procedural Terminology codes. Implants and associated charges were noted, as were sex, age, insurance status, surgeon specialty, and location. Bivariate and multivariable regression were used to determine associations. RESULTS: Total implant charges were significantly lower for 25607 (extraarticular, $3,348) than 25608 (2-part intraarticular, $3,859) and 25609 (3+ part intraarticular, $3,991). In addition, intra-articular fractures had higher charges for distal screws/pegs and bone graft. Charge was lower when surgery was performed at a trauma center. There was no charge difference associated with insurance status, age, sex, hand surgery specialty, or fellow status. Substantial intersurgeon variation existed in all fracture types. CONCLUSION: Distal radius fractures may represent a good model for examining implant costs. Extra-articular fractures had lower implant charges than intra-articular fractures. These data may be used to help construct pricing for distal radius fracture bundles and potential cost savings.

CASE: We present a case of a 41-year-old male bodybuilder with a partial delaminated quadriceps tendon rupture after a traumatic injury. Partial quadriceps tendon tears are rare overall and usually are treated nonoperatively with conservative management depending on the patient's limitations. He was found to have an intact superficial quadriceps tendon with a partial thickness tear of the vastus intermedius and delamination of the undersurface quadriceps tendon precluding active knee extension. CONCLUSION: To our knowledge, there has never been a reported partial quadriceps tendon tear with delamination of the undersurface, causing a complete extensor mechanism failure necessitating operative repair.

INTRODUCTION: A simple antibiotic prophylaxis initiative can effectively decrease the time to antibiotic administration for patients with open fractures. We aim to determine whether adherence to the protocol decreased over time without active input from the orthopaedic trauma team. PATIENTS AND METHODS: This retrospective cohort study included adult patients with open fractures (excluding hand) presenting directly to the emergency department at one Level I trauma center. Three separate 50-patient groups were included: a preimplementation cohort, immediately postimplementation cohort, and a retention cohort 2 years later. The primary outcome was time from emergency department presentation to antibiotic administration, and secondary outcomes were the percentage of patients receiving antibiotics within 60 minutes and incidence of infection requiring revision surgery within 90 days. The χ2 and Student t-tests evaluated between-group differences, and multivariable linear or logistic regression evaluated risk factors. RESULTS: After implementation, the time from presentation to antibiotic administration decreased markedly from 123.1 to 35.7 minutes and remained durable (50.0 minutes) at retention. The proportion of patients receiving antibiotics within 60 minutes increased markedly from 46% preimplementation to 82% postintervention and remained similar at retention (80%). The postintervention and retention groups were markedly more likely to receive antibiotics within 60 minutes than the preintervention group (odds ratio [OR], 8.4 and 4.7, respectively), as were patients with a higher Gustilo-Anderson type (OR, 2.4/unit increase), lower extremity injury (OR, 2.8), and male sex (OR, 3.1); mechanism, age, and Injury Severity Score were not associated. No difference was observed in infection. CONCLUSIONS: Our educational initiative showed durable results in reducing the time from presentation to antibiotic administration after 2 years. LEVEL OF EVIDENCE: Therapeutic Level III.

OBJECTIVES: Assess the burden and co-occurrence of pain, depression, and posttraumatic stress disorder (PTSD) among service members who sustained a major limb injury, and examine whether these conditions are associated with functional outcomes. DESIGN: A retrospective cohort study. SETTING: Four U.S. military treatment facilities: Walter Reed Army Medical Center, National Naval Medical Center, Brooke Army Medical Center, and Naval Medical Center San Diego. PATIENTS/PARTICIPANTS: Four hundred twenty-nine United States service members who sustained a major limb injury while serving in Afghanistan or Iraq met eligibility criteria upon review of their medical records. INTERVENTION: Not applicable. MAIN OUTCOME MEASUREMENTS: Outcomes assessed were: function using the short musculoskeletal functional assessment; PTSD using the PTSD Checklist and diagnostic and statistical manual criteria; pain using the chronic pain grade scale. RESULTS: Military extremity trauma and amputation/limb salvage patients without pain, depression, or PTSD, were, on average, about one minimally clinically important difference (MCID) from age- and gender-adjusted population norms. In contrast, patients with low levels of pain and no depression or PTSD were, on average, one to 2 MCIDs from population norms. Military extremity trauma and amputation/limb salvage patients with either greater levels of pain, and who experience PTSD, depression, or both, were 4 to 6 MCIDs from population norms. Regression analyses adjusting for injury type (upper or lower limb, salvage or amputation, and unilateral or bilateral), age, time to interview, military rank, presence of a major upper limb injury, social support, presence of mild traumatic brain injury/concussion, and combat experiences showed that higher levels of pain, depression, and PTSD were associated with lower one-year functional outcomes. CONCLUSIONS: Major limb trauma sustained in the military results in significant long-term pain and PTSD. Overall, the results are consistent with the hypothesis that pain, depression, and PTSD are associated with disability in this population. LEVEL OF EVIDENCE: Prognostic Level III.

BACKGROUND: Although periprosthetic fractures are increasing in prevalence, evidence-based guidelines for the optimal treatment of periprosthetic tibial fractures (PTx) are lacking. Thus, the purpose of this study is to assess the clinical outcomes in PTx after a total knee arthroplasty (TKA) which were treated with different treatment options. METHODS: A retrospective review was performed on a consecutive series of 34 nontumor patients treated at 2 academic institutions who experienced a PTx after TKA (2008-2016). Felix classification was used to classify fractures (Felix = I-II-III; subgroup = A-B-C) which were treated by closed reduction, open reduction/internal fixation, revision TKA, or proximal tibial replacement. Patient demographics and surgical characteristics were collected. Failure of treatment was defined as any revision or reoperation. Independent t-tests, one-way analysis of variance, chi-squared analyses, and Fisher's exact tests were conducted. RESULTS: Patients with Felix I had more nonsurgical complications when compared to Felix III patients (P = .006). Felix I group developed more postoperative anemia requiring transfusion than Felix III group (P = .009). All fracture types had >30% revision and >50% readmission rate with infection being the most common cause. These did not differ between Felix fracture types. Patients who underwent proximal tibial replacement had higher rate of postoperative infection (P = .030), revision surgery (P = .046), and required more flap reconstructions (P = .005). CONCLUSION: PTx after a TKA is associated with high revision and readmission rates. Patients with Felix type I fractures are at higher risk of postoperative nonsurgical complications and anemia requiring transfusion. Fractures treated with proximal tibial replacement are more likely to develop postoperative infections and undergo revision surgery.

Reconstruction of segmental diaphyseal bone defects has been a major challenge in limb salvage surgery. Staged reconstruction as first described by Masquelet is a common strategy to deal with this problem in limb salvage surgery. One consequence of this technique is a time period of prolonged limited weightbearing while the segmental defect heals. The purpose of this study was to describe an adjunctive technique for stage II of the Masquelet procedure and retrospectively analyze the outcome and weight bearing progression of 3 patients who sustained femur fractures with significant bone loss and underwent this technique. A retrospective chart review was performed. The patients (2 males, 1 female with an average age of 36.6 years) all sustained segmental femur fractures which resulted in significant bone loss. Induced membrane technique with adjunct use of a fibular strut allograft was performed after initial stabilization and PMMA spacer placement. All three patients went on to union and full weight bearing after being treated by the described technique. All the patients were allowed toe-touch weight bearing immediately after surgery and all progressed to weight bearing as tolerated at an average of 3.6 months. Using a fibular strut allograft as an adjunct to the induced membrane technique serves as a biologic and mechanical scaffold and may allow earlier weightbearing.

OBJECTIVES: To evaluate opioid-prescribing patterns after surgery for orthopaedic trauma before and after implementation of opioid-limiting mandates in one state. DESIGN: Retrospective review. SETTING: Level-1 trauma center. PATIENTS/PARTICIPANTS: Seven hundred fifty-three patients (297 pre-law and 456 post-law) undergoing isolated fixation for 6 common fracture patterns during specified pre-law (January 1, 2016-June 28, 2016) and post-law (June 01, 2017-December 31, 2017) study periods. Polytrauma patients were excluded. INTERVENTION: Implementation of statewide legislation establishing strict limits on initial opioid prescriptions [150 total morphine milligram equivalents (MMEs), 30 MMEs per day, or 20 total doses]. MAIN OUTCOME MEASUREMENTS: Initial opioid prescription dose, cumulative MMEs filled by 30 and 90 days postoperatively. RESULTS: Pre-law and post-law patient groups did not differ in terms of age, sex, opioid tolerance, recent benzodiazepine use, or open versus closed fracture pattern (P > 0.05). The post-law cohort received significantly less opioids (363.4 vs. 173.6 MMEs, P < 0.001) in the first postoperative prescription. Furthermore, the post-law group received significantly less cumulative MMEs in the first 30 postoperative days (677.4 vs. 481.7 MMEs, P < 0.001); This included both opioid-naïve (633.7 vs. 478.1 MMEs, P < 0.001) and opioid-tolerant patients (1659.2 vs. 880.0 MMEs, P = 0.048). No significant difference in opioid utilization between pre- and post-law groups was noted after postoperative day 30. Independent risk factors for prolonged (>30 days) postoperative opioid use included male gender (odds ratio 2.0, 95% confidence interval 1.4-2.9, P < 0.001) and preoperative opioid use (odds ratio 5.1, 95% confidence interval 2.4-10.5, P < 0.001). CONCLUSIONS: Opioid-limiting legislation is associated with a statistically and clinically significant reduction in initial and 30-day opioid prescriptions after surgery for orthopaedic trauma. Preoperative opioid use and male gender are independently associated with prolonged postoperative opioid use in this population. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: The purpose of this study was to assess the impact of adding a geriatric comanagement program to the care of geriatric patients with a hip fracture at our hospital. The Institute for Healthcare Improvement (IHI) Global Trigger Tool (GTT) was used to follow the frequency and severity of adverse events occurring in hospitalized patients and to examine the effectiveness of a comanagement program (the Geriatric Hip Fracture Program [GHFP]). METHODS: Data were collected for patients treated for a hip fracture from 2010 to 2014, which was 1 year prior to (October 2010 to September 2011) and 2 years after the implementation of the GHFP, and were grouped into 3-month intervals for analysis. The patients treated prior to the implementation of the GHFP were compared with those treated following the implementation of the program. The frequency and severity of adverse events were collected using the GTT. RESULTS: There were 75.9 patients with an adverse event and 160.7 adverse events per 100 admissions. After the institution of the GHFP, there was a significant decrease in the number of patients with adverse events and the number of adverse events per 100 admissions over time. The rate of adverse events decreased by 12% per year when acute blood loss anemia was excluded. Similarly, the number of adverse events (excluding blood loss anemia) decreased significantly over time, from 128.7 per 100 admissions before the GHFP to 34.2 in the last quarter. Multivariable analysis (excluding acute blood loss anemia) demonstrated a trend toward a decreased likelihood of a patient experiencing an adverse event after the institution of the GHFP as well as a trend toward a decrease in the number of adverse events per patient. The length of the hospital stay was significantly shorter after the implementation of the GHFP. CONCLUSIONS: The implementation of the GHFP reduced the number of adverse events over time. Increasing age and the Carlson Comorbidity Index (CCI) were predictors of adverse events, while only age was a predictor of readmissions and CCI was a predictor of death in our study. The implementation of the GHFP has played an important role at our institution in quantifying the decrease in adverse events over a 2-year period, and we believe that it is essential for improving care of geriatric patients with a hip fracture. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

INTRODUCTION: Young patients with femoral neck fractures are optimally treated with reduction and stable fixation, while patients over the age of sixty-five are often treated with arthroplasty. This study analyzes in-hospital outcomes associated with total hip arthroplasty, hip hemiarthroplasty and internal fixation for treatment of femoral neck fractures in patients aged 45-64. METHODS: Records of patients between the ages of 45-64, from 2002 to 2014, sustaining femoral neck fractures and treated with internal fixation, hip hemiarthroplasty or total hip arthroplasty were obtained from the Nationwide Inpatient Sample (NIS). Examined variables were age, sex and Charlson Comorbidity Index (CCI). Outcome measures included hospital length of stay (LOS), complications, and inpatient hospitalization charge. RESULTS: From 2002-2014 74,678 femoral neck fractures were available for analysis. THA use increased from 5.3% of operatively managed fractures in 2002 to 22.3% of operatively managed fractures in 2014 (p < 0.0001). Patients undergoing THA had higher hospital cost, higher in hospital complication rates and longer length of stay than patients undergoing internal fixation (p < 0.0001). The in-hospital mortality for patients undergoing a hip hemiarthroplasty was higher (1.2%) than either total hip arthroplasty (0.2%) or internal fixation (0.5%) (P = 0.007). CONCLUSION: This study demonstrates that the use of total hip arthroplasty in treatment of femoral neck fractures in patients from the age of 45-64 increased 4.2-fold over the study period. This treatment is associated with increased hospital cost, length of stay and complications. Additionally, as age increased in our study population, there was a stepwise increase in the use of arthroplasty, and it appears that hemiarthroplasty is being used with a different patient population.

INTRODUCTION: Pilon and unstable ankle fractures are often treated initially with an external fixator (ex-fix). Ex-fix application in the emergency department (ED) has been described but not compared with that placed in the operating room (OR). METHODS: Retrospective, case-cohort study was performed at a level-1 trauma center. Using CPT codes, we identified patients who had surgical fixation of pilon or ankle fractures with an initial ex-fix application (in the ED or the OR). Postoperative outcomes and hospital logistical data were compared between the two groups. RESULTS: Ninety-six patients met the inclusion criteria. The average age of patients was 47 years, and 54 (56%) of the patients were men. Thirty-three patients had the ex-fix placed in the OR, whereas 63 patients had the ex-fix placed in the ED. Postsurgical complications (prominent implant, nonunion, deep infection, deep vein thrombosis, loss of reduction) were seen in 6 of 33 patients in the ED ex-fix group and in 8 of 63 patients in the OR ex-fix group (P = 0.51). Deep infections occurred in 2 of 33 patients in the OR ex-fix group and in 5 of 63 patients in the ED ex-fix group (P = 0.71). Revision ex-fix for loss of reduction was performed in 4 of 33 patients in the OR ex-fix group and in 10 of 63 patients in the ED ex-fix group (P = 0.59). Mean length of stay was 14 days for the OR ex-fix group and 13 days for the ED ex-fix group (P = 0.35). CONCLUSION: No statistically significant differences were found in postsurgical complications (surgical or infectious) or ex-fix revision rates for the ED ex-fix group and the OR ex-fix group. Results indicate that uniplanar ex-fix may be safely applied in the ED. LEVEL OF EVIDENCE: Level III, therapeutic.

Orthopaedic surgeons are routinely exposed to intraoperative radiation and, therefore, follow the principle of "as low as reasonably achievable" with regard to occupational safety. However, standardized education on the long-term health effects of radiation and the basis for current radiation exposure limits is limited in the field of orthopaedics. Much of orthopaedic surgeons' understanding of radiation exposure limits is extrapolated from studies of survivors of the atomic bombings in Hiroshima and Nagasaki, Japan. Epidemiologic studies on cancer risk in surgeons and interventional proceduralists and dosimetry studies on true radiation exposure during trauma and spine surgery recently have been conducted. Orthopaedic surgeons should understand the basics and basis of radiation exposure limits, be familiar with the current literature on the incidence of solid tumors and cataracts in orthopaedic surgeons, and understand the evidence behind current intraoperative fluoroscopy safety recommendations.

INTRODUCTION: Hip fractures account for a significant disease burden in the Unites States. With an aging population, this disease burden is expected to increase in the upcoming decades. MATERIALS AND METHODS: This represents a retrospective cohort study to assess mortality following hip fracture in the octogenarian and nonagenarian populations. Odds ratios for postoperative mortality were constructed using normalized patients from United States Social Security death tables. Kaplan Meier analysis and binary logistic regression were used to assess the impact of surgical delay and medical comorbidity (measured by the Carlson Comorbidity Index (CCI)) on postoperative mortality. RESULTS: 189 octogenarians and 95 nonagenarians were included. One-year mortality was nearly three times higher for both the octogenarians (OR: 3.1) and nonagenarians (OR: 3.14), and returned to that of the normal population 4 years post-op for octogenarians and 5 years post-op for nonagenarians. Higher preoperative medical comorbidity (CCI) was associated with higher post-op mortality for both octogenarians (log rankâ¯=â¯0.026) and nonagenarians (log rankâ¯=â¯0.034). A 48-h surgical delay resulted in significantly increased postoperative mortality among healthy patients (CCI of 0 or 1, OR: 18.1), but was protective for patients with significant medical comorbidity (CCIâ¯≥â¯3). Age, preoperative CCI, and 48-h surgical delay were all independent predictors of 1-year post-op mortality. CONCLUSIONS: Following hip fracture, there is a 3-fold increase in mortality for octogenarians and nonagenarians at 1 year post-op. A 48-h surgical delay significantly increased mortality for healthier patients but was protective against mortality for sicker patients.

OBJECTIVES: With rising rates of obesity in the United States, the burden of knee dislocations in this population remains unknown. This national epidemiologic study was designed to analyze the association of obesity with closed knee dislocation and vascular complications. DESIGN: Retrospective cohort study. SETTING: The deidentified Nationwide Inpatient Sample database was used to access the US inpatient data from 2000 to 2012. PATIENTS/PARTICIPANTS: Patients with noncongenital closed knee dislocations were included. Examined variables included patient age, sex, vascular injury, and obesity status. MAIN OUTCOME MEASURES: Outcome measures included hospital length of stay, amputation, and inpatient hospitalization charge. RESULTS: From 2000 to 2012, a total of 19,087 knee dislocations were identified, including 2265 in overweight/obese patients (11.9%). The annual incidence of knee dislocations reported in patients diagnosed as either obese or morbidly obese increased over the 13-year period (P < 0.0001). The overall average rate of vascular injury requiring intervention was 5.63%, whereas 7.2% of obese patients and 11.3% of morbidly obese patients with knee dislocations (P < 0.0001) sustained a vascular injury requiring intervention. The average length of stay and amputation rate for obese and morbidly obese patients who sustained a knee dislocation was not statistically different from nonobese patients when vascular injury was controlled. When patients with a vascular injury were excluded, obese and morbidly obese patients who sustained a knee dislocation had higher average cost of hospital stay than nonobese patients (P = 0.0262). CONCLUSIONS: This study demonstrates significant increases in costs of stay with obese patients sustaining knee dislocations when compared with normal weight knee dislocation patients. Vascular injuries were found to be far more common in obese and morbidly obese patient groups than nonobese patients. Providers should be on high alert when managing knee dislocations in obese patients because a significant number require prompt vascular intervention. LEVEL OF EVIDENCE: Prognostic Level III.

OBJECTIVES: While osteoporosis has been shown to be a contributing factor in low energy fractures in the elderly, limited data exists regarding the correlation of bone mineral density (BMD) and T-Scores to mortality and failure of fracture fixation. This study seeks to determine the relationship between femoral neck BMD in elderly patients with typical geriatric fractures and mortality and fracture fixation failure using Quantitative Computed Tomography (QCT). MATERIALS AND METHODS: Patients over the age of 65 who sustained fractures of the proximal humerus, distal radius, pelvic ring, acetabulum, hip, proximal tibia, and ankle who also underwent a CT scan that included an uninjured femoral neck were retrospectively reviewed. QCT was used to assess bone mineral density and T scores. Mortality and fixation failure were recorded. Standard descriptive statistics, as well as logistic regression were used to correlate BMD and mortality, and BMD and fixation failure. RESULTS: Of the 173 patients initially screened, 150 met inclusion criteria. Patients who remained alive at the end of the study (LP) had significantly (Pâ¯=â¯.019) higher adjusted mean femoral neck BMD (0.502â¯g/cm2) than non-polytrauma patients who died (MNPT) (0.439â¯g/cm2) when controlling for age, time to mortality, follow up, CCI, and ASA. Patients who had fixation failure events (FE) had significantly (Pâ¯=â¯.002) lower adjusted mean femoral neck BMD (0.342â¯g/cm2) than patients without failure events (NE) (0.525â¯g/cm2) when controlling for age and time to radiographic follow-up. CONCLUSIONS: Our study illustrates that QCT is a reliable method for the determination of femoral neck BMD in elderly patients with geriatric fractures. Furthermore, lower BMD/T-Scores are associated with increased mortality and fixation failures in this patient population.

OBJECTIVE: To determine whether time to administration of antibiotics decreased after the implementation of an open fracture working group and antibiotic prophylaxis protocol. DESIGN: Retrospective cohort study. SETTING: One Level 1 Trauma Center. PATIENTS: Patients 18 years of age and older who sustained an open fracture and presented directly to our emergency department. INTERVENTION: Prompt irrigation and debridement in the operating room and fracture stabilization dictated by the treating surgeon. Fifty patients were reviewed as the preintervention group, comprising the period before conception and before intervention. Fifty patients were included after the initiation of our protocol during the same time period 1 year later. MAIN OUTCOME MEASUREMENTS: Time from entrance to the emergency department to ordering of antibiotics, time from ordering to administration of antibiotics, and time from entrance to the emergency department to administration of antibiotics. RESULTS: After protocol implementation, time from admission to antibiotic administration decreased significantly from 123.1 to 35.7 minutes (P = 0.0003). Each component decreased significantly: admission to order decreased from 94.1 to 26.1 minutes, and order to administration decreased from 29.0 to 9.5 minutes (P = 0.0046 and P = 0.0003). CONCLUSION: Our study demonstrates a significantly reduced time to antibiotic prophylaxis for patients with open fractures after the implementation of a multidisciplinary working group. We hope that this provides a model for institutions to improve care and outcomes of these injuries. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVES: To compare the static and dynamic mechanical properties of a modified crossed cannulated screw (CS) configuration, the inverted triangle (IT) cannulated screw configuration, and a compression hip screw (CHS) with derotation screw in Pauwels type III femoral neck fractures. METHODS: Thirty synthetic femora were divided into 3 groups, and vertical femoral neck osteotomies were made. Ten osteotomized femora were fixed with a CS configuration, 10 were fixed with 3 parallel screws in an IT configuration, and the remaining 10 osteotomized femora were fixed with a CHS construct. All groups were tested using a cyclic (up to 15,000 load cycles) axial loading protocol, and survivors were statically loaded to failure. Cycles to failure, load to failure, and stiffness were calculated. The Kaplan-Meier method was used to estimate survival functions and were compared among fixation methods. The relationship between construct structural properties (maximum load and stiffness) and treatment were assessed using general linear modeling. RESULTS: All CHS fixation constructs survived the 15,000 cycle loading protocol. They endured longer (P = 0.034) than the CS fixation constructs (mean failure 13,332 cycles), but were not different from IT fixation constructs (mean failure 13,592 cycles). Maximum loads to failure for CS (3870 N) and IT (3756 N) fixation constructs were not different, but were less (P < 0.0001) than the maximum loads to failure for the CHS fixation constructs (5654 N). These findings parallel the results of the axial stiffness measurements: CS fixation constructs (663.01 N/mm) were not stiffer than IT fixation constructs (620.0 N/mm), but were less (P = 0.0005) than the axial stiffness of the CHS fixation constructs (1241.86 N/mm). CONCLUSIONS: The biomechanical performance of the CHS fixation method was superior to both the CS fixation method and the IT fixation method using a synthetic femoral model and this test protocol. Biomechanical performance of the latter 2 groups was indistinguishable. We recommend the use of CHS with the derotational screw construct for Pauwels III femoral neck fractures whenever possible.

Suture button devices such as the TightRope (Arthrex, Naples, Florida) have been increasingly used for syndesmotic fixation of ankle fractures. Despite proposed advantages, prior studies have shown equivalent outcomes, with a theoretical decreased need for removal of hardware. Complications of suture button fixation of syndesmotic instability may be underreported and include lateral suture knot inflammation with or without granuloma formation, infection, aseptic osteolysis with widening of the tibial drill tunnels, heterotopic ossification, and osteomyelitis. In this case series, the authors review the current literature and describe 3 patients with TightRope fixation for syndesmotic instability who developed deep infection. The authors believe that braided suture within suture button devices may provide an environment conducive to the propagation of infection across the syndesmotic fixation tract. Evidence of suture button migration or osteolysis of the TightRope tract should prompt an infectious workup and removal of hardware. If there is concern for infection associated with the TightRope, the authors recommend removing both metallic buttons and the entirety of the suture to prevent harboring a nidus for further infection.

Hemorrhage continues to be the most common cause of death among service members wounded in combat. Injuries that were previously nonsurvivable in previous wars are now routinely seen by combat surgeons in forward surgical units, the result of improvements in body armor, the universal use of field tourniquets to control extremity hemorrhage at the point of injury, and rapid air evacuation strategies. Combat orthopaedic surgeons remain a vital aspect of the forward surgical unit, tasked with assisting general surgical colleagues in the resuscitation of patients in hemorrhagic shock while also addressing traumatic amputations, open and closed long bone fractures, and mechanically unstable pelvic trauma. Future military and civilian trauma research endeavors will seek to identify how the advances made in the past 15 years will translate toward the emerging battlefield of the future, one where forward surgical units must be lighter, smaller, and more mobile to address the changing scope of military combat operations.
RESUMO
Successful management of the mangled extremity is difficult; however, recent advancements are changing the outcomes of these difficult cases. Multiple centers are working on new bionic limbs with real-time feedback and better performance parameters. Research progress, particularly in the military sector, has aided in our understanding of heterotopic ossification after devastating limb injuries. This progress has also allowed a better treatment program for the residual limb in surgery and postsurgery. It is an exciting time in the management and rehabilitation of amputated limbs, as both biologic and technological advancements are enabling better patient satisfaction. This article looks at some of these discoveries and how they are changing the treatment of the residual limb.
