RESUMO

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) plays a vital role in providing life support for patients with reversible cardiac or respiratory failure. Given the high rate of complications and difficulties associated with caring for ECMO patients, the goal of this study was to compare outcomes of orthopaedic surgery in polytrauma patients who received ECMO with similar patients who have not. This will help elucidate the timing and type of fixation that should be considered in patients on ECMO. METHODS: A retrospective cohort was collected from the electronic medical record of two level I trauma centers over an 8-year period (2015 to 2022) using Current Procedural Terminology codes. Patients were matched with a similar counterpart not requiring ECMO based on sex, age, American Society of Anesthesiologists score, body mass index, injury severity score, and fracture characteristics. Outcomes measured included length of stay, number of revisions, time to definitive fixation, infection, amputation, revision surgery to promote bone healing, implant failure, bleeding requiring return to the operating room, and mortality. RESULTS: Thirty-two patients comprised our ECMO cohort with a patient-matched control group. The ECMO cohort had an increased length of stay (40 versus 17.5 days, P = 0.001), number of amputations (7 versus 0, P = 0.011), and mortality rate (19% versus 0%, P = 0.024). When comparing patients placed on ECMO before definitive fixation and after definitive fixation, the group placed on ECMO before definitive fixation had significantly longer time to definitive fixation than the group placed on ECMO after fixation (14 versus 2.0 days, P < 0.001). CONCLUSION: ECMO is a lifesaving measure for trauma patients with cardiopulmonary issues but can complicate fracture care. Although it is not associated with an increase in revision surgery rates, ECMO was associated with prolonged hospital stay and delays in definitive fracture surgery when initiated before definitive fixation. LEVEL OF EVIDENCE: III.

RESUMO

OBJECTIVES: To analyze the relationship between patient resilience and patient-reported outcomes after orthopaedic trauma. DESIGN: Retrospective analysis of prospectively collected data. SETTING: Single Level 1 Trauma Center. PATIENT SELECTION CRITERIA: Patients were selected based on completion of the Patient-Reported Outcomes Measurement Information System (PROMIS) and Brief Resilience Scale (BRS) surveys 6 months after undergoing operative fracture fixation following orthopaedic trauma. Patients were excluded if they did not complete all PROMIS and BRS surveys. OUTCOME MEASURES AND COMPARISONS: Resilience, measured by the BRS, was analyzed for its effect on patient-reported outcomes, measured by PROMIS Global Physical Health, Physical Function, Pain Interference, Global Mental Health, Depression, and Anxiety. Variables collected were demographics (age, gender, race, body mass index), injury severity score, and postoperative complications (nonunion, infection). All variables were analyzed with univariate for effect on all PROMIS scores. Variables with significance were included in multivariate analysis. Patients were then separated into high resilience (BRS >4.3) and low resilience (BRS <3.0) groups for additional analysis. RESULTS: A total of 99 patients were included in the analysis. Most patients were male (53%) with an average age of 47 years. Postoperative BRS scores significantly correlated with PROMIS Global Physical Health, Pain Interference, Physical Function, Global Mental Health, Depression, and Anxiety ( P ≤ 0.001 for all scores) at 6 months after injury on both univariate and multivariate analyses. The high resilience group had significantly higher PROMIS Global Physical Health, Physical Function, and Global Mental Health scores and significantly lower PROMIS Pain Interference, Depression, and Anxiety scores ( P ≤ 0.001 for all scores). CONCLUSIONS: Resilience in orthopaedic trauma has a positive association with patient outcomes at 6 months postoperatively. Patients with higher resilience report higher scores in all PROMIS categories regardless of injury severity. Future studies directed at increasing resilience may improve outcomes in patients who experience orthopaedic trauma. LEVEL OF EVIDENCE: Prognostic Level III.

RESUMO

OBJECTIVES: To assess the relationship between patient smoking status and fracture-related infection (FRI) characteristics including patient symptoms at FRI presentation, bacterial species of FRI, and rates of fracture union. DESIGN: Retrospective cohort study. SETTING: Urban level 1 trauma center. PATIENT SELECTION CRITERIA: All patients undergoing reoperation for FRI from January 2013 to April 2021 were identified through manual review of an institutional database. OUTCOME MEASURES AND COMPARISONS: Data including patient demographics, fracture characteristics, infection presentation, and hospital course were collected through review of the electronic medical record. Patients were grouped based on current smoker versus nonsmoker status. Hospital course and postoperative outcomes of these groups were then compared. Risk factors of methicillin-resistant Staphylococcus aureus (MRSA) infection, Staphylococcus epidermidis infection, and sinus tract development were evaluated using multivariable logistic regression. RESULTS: A total of 301 patients, comprising 155 smokers (51%) and 146 nonsmokers (49%), undergoing FRI reoperation were included. Compared with nonsmokers, smokers were more likely male (69% vs. 56%, P = 0.024), were younger at the time of FRI reoperation (41.7 vs. 49.5 years, P < 0.001), and had lower mean body mass index (27.2 vs. 32.0, P < 0.001). Smokers also had lower prevalence of diabetes mellitus (13% vs. 25%, P = 0.008) and had higher Charlson Comorbidity Index 10-year estimated survival (93% vs. 81%, P < 0.001). Smokers had a lower proportion of S. epidermidis infections (11% vs. 20%, P = 0.037), higher risk of nonunion after index fracture surgery (74% vs. 61%, P = 0.018), and higher risk of sinus tracts at FRI presentation (38% vs. 23%, P = 0.004). On multivariable analysis, smoking was not found to be associated with increased odds of MRSA infection. CONCLUSIONS: Among patients who develop a FRI, smokers seemed to have better baseline health regarding age, body mass index, diabetes mellitus, and Charlson Comorbidity Index 10-year estimated survival compared with nonsmokers. Smoking status was not significantly associated with odds of MRSA infection. However, smoking status was associated with increased risk of sinus tract development and nonunion and lower rates of S. epidermidis infection at the time of FRI reoperation. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

PURPOSE: To assess if pes anserinus tenotomy (PAT) during definitive open reduction and internal fixation (ORIF) of tibial plateau fractures is associated with a decreased risk of surgical site infection (SSI) and other postoperative complications. METHODS: A retrospective review of all adults who underwent ORIF for tibial plateau fractures from April 2005 to February 2022 at single level 1 trauma center was performed. Patients who had a medial approach to the plateau with minimum three-month follow-up were required for inclusion. All patients with fasciotomy for compartment syndrome or with traumatically avulsed or damaged pes anserinus prior to ORIF were excluded. Two groups were created: those who received a pes anserinus tenotomy with repair (PAT group) and those whose pes anserinus were spared and left intact (control group). Patient demographics, injury and operative characteristics, and surgical outcomes were compared. The primary outcomes were rates of deep and superficial SSI. RESULTS: The PAT group had significantly lower rates of deep SSI (9.2% vs. 19.7%, P = 0.009), superficial SSI (14.2% vs. 26.5%), P = 0.007), and any SSI (15.8% vs. 28.9%, P = 0.005). Multiple logistic regression showed that heart failure (aOR = 7.215, 95% CI 2.291-22.719, P < 0.001), and presence of open fracture (aOR = 4.046, 95% CI 2.074-7.895, P < 0.001) were independently associated with increased odds of deep SSI, while PAT was associated with a decreased odds of deep SSI (aOR = 0.481, 95% CI 0.231-0.992, P = 0.048). PAT had significantly lower rates of unplanned return to the operating room (20.8% vs. 33.7%, P = 0.010) and implant removal (10.0% vs. 18.0%, P = 0.042). CONCLUSION: While these data do not allow for discussion of functional recovery or strength, pes anserinus tenotomy was independently associated with significantly lower rates of infection, unplanned operation, and implant removal. LEVEL OF EVIDENCE: Level III.

RESUMO

OBJECTIVES: Evaluate the effect of anterior fixation on infection in patients with operative pelvic fractures and bladder or urethral injuries. DESIGN: Retrospective. SETTING: Eight centers. PATIENT SELECTION CRITERIA: Adult patients with closed pelvic fractures with associated bladder or urethral injuries treated with anterior plating (AP), intramedullary screw (IS), or no anterior internal fixation (NAIF, including external fixation or no fixation). OUTCOME MEASURES AND COMPARISONS: Deep infection. RESULTS: There were 81 extraperitoneal injuries and 57 urethral injuries. There was no difference in infection between fixation groups across all urologic injuries (AP: 10.8%, IS: 0%, NAIF: 4.9%, P = 0.41). There was a higher rate of infection in the urethral injury group compared with extraperitoneal injuries (14.0% vs. 2.5%, P = 0.016). Among extraperitoneal injuries, specifically, there was no difference in deep infection related to fixation (AP: 2.6%, IS 0%, NAIF: 2.9%, P = 0.99). Among urethral injuries, there was no statistical difference in deep infection related to fixation (AP: 23.1%, IS: 0%, NAIF: 7.4%, P = 0.21). There was a higher rate of suprapubic catheter (SPC) use in urethral injuries compared with extraperitoneal injuries (57.9% vs. 4.9%, P < 0.0001). In the urethral injury group, SPC use did not have a statistically significant difference in infection rate (SPC: 18.2% vs. No SPC: 8.3%, P = 0.45). Early removal of the SPC before or during the definitive orthopaedic intervention did not significantly affect infection rate (early: 0% vs. delayed: 25.0%, P = 0.16). CONCLUSIONS: Surgeons should approach operative pelvic fractures with associated urologic injuries with caution given the high risk of infection. Further work must be done to elucidate the effect of anterior implants and SPC use and duration. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

BACKGROUND: The objective of this study was to investigate the outcomes of COVID-19-positive patients undergoing orthopaedic fracture surgery using data from a national database of U.S. adults with a COVID-19 test for SARS-CoV-2. METHODS: This is a retrospective cohort study using data from a national database to compare orthopaedic fracture surgery outcomes between COVID-19-positive and COVID-19-negative patients in the United States. Participants aged 18-99 with orthopaedic fracture surgery between March and December 2020 were included. The main exposure was COVID-19 status. Outcomes included perioperative complications, 30-day all-cause mortality, and overall all-cause mortality. Multivariable adjusted models were fitted to determine the association of COVID-positivity with all-cause mortality. RESULTS: The total population of 6.5 million patient records was queried, identifying 76,697 participants with a fracture. There were 7,628 participants in the National COVID Cohort who had a fracture and operative management. The Charlson Comorbidity Index was higher in the COVID-19-positive group (n = 476, 6.2 %) than the COVID-19-negative group (n = 7,152, 93.8 %) (2.2 vs 1.4, p<0.001). The COVID-19-positive group had higher mortality (13.2 % vs 5.2 %, p<0.001) than the COVID-19-negative group with higher odds of death in the fully adjusted model (Odds Ratio=1.59; 95 % Confidence Interval: 1.16-2.18). CONCLUSION: COVID-19-positive participants with a fracture requiring surgery had higher mortality and perioperative complications than COVID-19-negative patients in this national cohort of U.S. adults tested for COVID-19. The risks associated with COVID-19 can guide potential treatment options and counseling of patients and their families. Future studies can be conducted as data accumulates. LEVEL OF EVIDENCE: Level III.

RESUMO

OBJECTIVES: To determine if nail plate constructs have lower rates of reoperation to promote bone healing than lateral locking plates in the treatment of distal femur fractures. DESIGN: Retrospective Cohort. SETTING: Single Level 1 trauma centerPatients/Participants: 312 consecutive patients treated operatively for native distal femur fractures (OTA/AO 33A or 33C). INTERVENTION: Reduction and fixation of distal femur fractures with either a lateral locked plate (LLP) or a nail plus plate construct (NPC). MAIN OUTCOME MEASURES: reoperation to promote bone healing at any time after definitive fixation. RESULTS: 279 fractures were treated with LLP and were compared with and 33 fractures treated with NPC constructs. Patient demographics, injury severity score (ISS), and frequency utilization of each construct between different types of OTA/AO classified distal femur fractures were similar. The reoperation rate to promote bone healing was 18.7% (51/273) for LLPs, and 3% (1/33) for NPC constructs. There was no significant difference in surgical site infection (SSI) (p = 0.67). CONCLUSIONS: Utilization of NPC technique demonstrated a significant decrease in rates of reoperation to promote bone healing compared to LLP alone in the treatment of OTA/AO 33A and 33C distal femur fractures. Augmented fixation with NPCs should be considered to treat complex distal femur fractures as it is associated with lower rates of reoperation to promote bone healing in comparison to LLP. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

PURPOSE: The objective of this study was to determine the underlying factors that drive the decision for surgeons to pursue operative versus nonoperative management for proximal humerus fractures (PHF) and if fellowship training had an impact on these decisions. METHODS: An electronic survey was distributed to members of the Orthopaedic Trauma Association and the American Shoulder and Elbow Surgeons Society to assess differences in patient selection for operative versus nonoperative management of PHF. Descriptive statistics were reported for all respondents. RESULTS: A total of 250 fellowship trained Orthopaedic Surgeons responded to the online survey. A greater proportion of trauma surgeons preferred nonoperative management for displaced PHF fractures in patients over the age of 70. Operative management was preferred for older patients with fracture dislocations (98%), limited humeral head bone subchondral bone (78%), and intraarticular head split (79%). Similar proportions of trauma surgeons and shoulder surgeons cited that acquiring a CT was crucial to distinguish between operative and nonoperative management. CONCLUSION: We found that surgeons base their decisions on when to operate primarily on patient's comorbidities, age, and the amount of fracture displacement when treating younger patients. Further, we found a greater proportion of trauma surgeons elected to proceed with nonoperative management in patients older than the age of 70 years old as compared to shoulder surgeons.

RESUMO

BACKGROUND: There is limited literature comparing the publications on ankle arthrodesis (AA) and total ankle arthroplasty (TAA) in the setting of hemophilic arthropathy. Our objective is to systematically review the existing literature and to assess ankle arthroplasty as an alternative to ankle arthrodesis in this patient population. METHODS: This systematic review was conducted and presented according to the PRISMA statement standards. A search was conducted on March 7-10, 2023, using MEDLINE (via PubMed), Embase, Scopus, ClinicalTrials.gov, CINAHL Plus with Full Text, and the Cochrane Central Register of Controlled Studies. This search was restricted to full-text human studies published in English, and articles were screened by 2 masked reviewers. Systematic reviews, case reports with less than 3 subjects, letters to the editor, and conference abstracts were excluded. Two independent reviewers rated study quality using the MINORS tool. RESULTS: Twenty-one of 1226 studies were included in this review. Thirteen articles reviewed the outcomes associated with AA in hemophilic arthropathy whereas 10 reviewed the outcomes associated with TAA. Two of our studies were comparative and reviewed the outcomes of both AA and TAA. Additionally, 3 included studies were prospective. Studies showed that the degree of improvement in American Orthopaedic Foot & Ankle Society hindfoot-ankle score, visual analog scale pain scores, and the mental and physical component summary scores of the 36-Item Short Form Health Survey were similar for both surgeries. Complication rates were also similar between the 2 surgeries. Additionally, studies showed a significant improvement in ROM after TAA. CONCLUSION: Although the level of evidence in this review varies and results should be interpreted with caution, the current literature suggests similar clinical outcomes and complication rates between TAA and AA in this patient population.

RESUMO

OBJECTIVES: To assess the ability of computed tomography angiography identified infrapopliteal vascular injury to predict complications in tibia fractures that do not require vascular surgical intervention. DESIGN: Multicenter retrospective review. SETTING: Six Level I trauma centers. PATIENTS AND INTERVENTION: Two hundred seventy-four patients with tibia fractures (OTA/AO 42 or 43) who underwent computed tomography angiography maintained a clinically perfused foot not requiring vascular surgical intervention and were treated with an intramedullary nail. Patients were grouped by the number of vessels below the trifurcation that were injured. MAIN OUTCOME MEASUREMENTS: Rates of superficial and deep infection, amputation, unplanned reoperation to promote bone healing (nonunion), and any unplanned reoperation. RESULTS: There were 142 fractures in the control (no-injury) group, 87 in the one-vessel injury group, and 45 in the two-vessel injury group. Average follow-up was 2 years. Significantly higher rates of nerve injury and flap coverage after wound breakdown were observed in the two-vessel injury group. The two-vessel injury group had higher rates of deep infection (35.6% vs. 16.9%, P = 0.030) and unplanned reoperation to promote bone healing (44.4% vs. 23.9%, P = 0.019) compared with controls, as well as increased rates of any unplanned reoperation compared with control and one-vessel injury groups (71.1% vs. 39.4% and 51.7%, P < 0.001), respectively. There were no significant differences in rates of superficial infection or amputation. CONCLUSIONS: Tibia fractures with two-vessel injuries were associated with higher rates of deep infection and unplanned reoperation to promote bone healing compared with those without vascular injury, as well as increased rates of any unplanned reoperation compared with controls and fractures with one-vessel injury. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVES: To evaluate the effect of translation on a large series of low-energy proximal humerus fractures initially treated nonoperatively. DESIGN: Retrospective multicenter analysis. SETTING: Five level-one trauma centers. PATIENTS/PARTICIPANTS: Two hundred ten patients (152 F; 58 M), average age 64, with 112 left- and 98 right-sided low-energy proximal humerus fractures (OTA/AO 11-A-C). INTERVENTION: All patients were initially treated nonoperatively and were followed for an average of 231 days. Radiographic translation in the sagittal and coronal planes was measured. Patients with anterior translation were compared with those with posterior or no translation. Patients with ≥80% anterior humeral translation were compared with those with <80% anterior translation, including those with no or posterior translation. MAIN OUTCOMES: The primary outcome was failure of nonoperative treatment resulting in surgery and the secondary outcome was symptomatic malunion. RESULTS: Nine patients (4%) had surgery, 8 for nonunion and 1 for malunion. All 9 patients (100%) had anterior translation. Anterior translation compared with posterior or no sagittal plane translation was associated with failure of nonoperative management requiring surgery ( P = 0.012). In addition, of those with anterior translation, having ≥80% anterior translation compared with <80% was also associated with surgery ( P = 0.001). Finally, 26 patients were diagnosed with symptomatic malunion, of whom translation was anterior in 24 and posterior in 2 ( P = 0.0001). CONCLUSIONS: In a multicenter series of proximal humerus fractures, anterior translation of >80% was associated with failure of nonoperative care resulting in nonunion, symptomatic malunion, and potential surgery. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

Open pelvic ring injuries are rare clinical entities that require multidisciplinary care. Due to the scarcity of this injury, there is no well-defined treatment algorithm. As a result, conflicting evidence surrounding various aspects of care including wound management and fecal diversion remain. Previous studies have shown mortality reaching 50% in open pelvic ring injuries, nearly five times higher than closed pelvic ring injuries. Early mortality is due to exsanguinating hemorrhage, while late mortality is due to wound sepsis and multiorgan system failure. With advancements in trauma care and ATLS protocols, there has been an improved survival rate reported in published case series. Major considerations when treating these injuries include aggressive resuscitation with hemorrhage control, diagnosis of associated injuries, prevention of wound sepsis with early surgical management, and definitive skeletal fixation. Classification systems for categorization and management of bony and soft tissue injury related to pelvic ring injuries have been established. Fecal diversion has been proposed to decrease rates of sepsis and late mortality. While clear indications are lacking due to limited studies, previous studies have reported benefits. Further large-scale studies are necessary for adequate evaluation of treatment protocols of open pelvic ring injuries. Understanding the role of fecal diversion, avoidance of primary closure in open pelvic ring injuries, and importance of well-coordinated care amongst surgical teams can optimize patient outcomes.

RESUMO

The purpose of this study was to investigate the association between pre-operative anemia and prolonged hospital stay among geriatric patients with operative femoral neck fractures. This retrospective cohort study was performed at a level I trauma center and included geriatric patients with femoral neck fractures (OTA/AO 31) and operative treatment with Current Procedural Terminology code 27236. Exclusion criteria were admission to the intensive care unit, evacuation of subdural hematoma, and conditions requiring exploratory laparotomy. A total of 207 individuals, with data collected between January 2015 and August 2019 and age 65 years and older, were included in the analysis. Linear regression was used to evaluate the association between anemia and length of stay adjusting for potential confounders. Anemia was defined using preoperative hematocrit. The primary outcome was prolonged length of stay, defined as 5 or more days. The group was 65% women. The mean age was 80.2 years (range, 64-98 years). The majority (61%) of patients had anemia. American Society of Anesthesiologists classification was associated with preoperative anemia (P=.02). Patients with anemia had a 16% higher risk of prolonged length of stay compared with patients without anemia (81% vs 65%, P=.009). In the linear regression model, preoperative hematocrit was associated with length of stay (P=.032) when adjusted for sex, age, preoperative tranexamic acid, preoperative hemoglobin, postoperative hemoglobin, and postoperative hematocrit. Length of stay was approximately 1 week in this study, with anemia being a statistically significant risk factor for prolonged length of stay. Health care providers and administrators can consider anemia on admission when predicting length of stay. [Orthopedics. 2023;46(4):211-217.].

RESUMO

OBJECTIVE: To compare outcomes of Masquelet-induced membrane technique (IMT) in metaphyseal and diaphyseal fractures with acute bone loss. DESIGN: Retrospective cohort study. SETTING: Four Level 1 Academic Trauma Centers. PATIENTS/PARTICIPANTS: Patients acutely treated with IMT for traumatic lower extremity bone loss at 4 Level 1 trauma centers between 2010 and 2020. INTERVENTION: Operative treatment with placement of cement spacer within 3 weeks of initial injury followed by staged removal and bone grafting to the defect. MAIN OUTCOME MEASUREMENTS: Fracture union, infection, revision grafting, time to union, and amputation. RESULTS: One hundred twenty fractures met inclusion criteria, including 43 diaphyseal fractures (DIM) and 77 metaphyseal fractures (MIM). Demographic characteristics were not significantly different, except for age (DIM 34 years vs. MIM 43 years, P < 0.001). Union after treatment with IMT was 89.2% overall. After controlling for age, this was not significantly different between DIM (41/43, 95.3%) and MIM (66/77, 85.7%) ( P = 0.13) nor was the rate of infection between groups. There was no difference in any secondary outcomes. CONCLUSIONS: The overall union rate in the current series of acute lower extremity fractures treated with the induced membrane technique was 89%. There was no difference in successful union between patients with diaphyseal bone loss or metaphyseal bone loss treated with IMT. Similarly, there was no difference in patients with tibial or femoral bone loss treated with induced membrane. Defect size after debridement may be more prognostic for secondary operations rather than the limb segment involved or the degree of soft-tissue injury. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVES: To determine risk factors for early conversion total hip arthroplasty (THA) in Pipkin IV femoral head fractures. DESIGN: Retrospective cohort. SETTING: Two level I trauma centers. PATIENTS AND INTERVENTION: One hundred thirty-seven patients with Pipkin IV fractures meeting inclusion criteria with 1 year minimum follow-up managed from 2009 to 2019. MAIN OUTCOME MEASUREMENT: Patients were separated into groups by the Orthopaedic Trauma Association/AO Foundation (OTA/AO) classification of femoral head fracture: 31C1 (split-type fractures) and 31C2 (depression-type fractures). Multivariable regression was performed after univariate analysis comparing patients requiring conversion THA with those who did not. RESULTS: We identified 65 split-type fractures, 19 (29%) underwent conversion THA within 1 year. Surgical site infection ( P = 0.002), postoperative hip dislocation ( P < 0.0001), and older age ( P = 0.049) resulted in increased rates of conversion THA. However, multivariable analysis did not identify independent risk factors for conversion. There were 72 depression-type fractures, 20 (27.8%) underwent conversion THA within 1 year. Independent risk factors were increased age ( P = 0.01) and posterior femoral head fracture location ( P < 0.01), while infrafoveal femoral head fracture location ( P = 0.03) was protective against conversion THA. CONCLUSION: Pipkin IV fractures managed operatively have high overall risk of conversion THA within 1 year (28.5%). Risk factors for conversion THA vary according to fracture subtype. Hip joint survival of fractures subclassified OTA/AO 31C1 likely depends on patient age and postoperative outcomes such as surgical site infection and redislocation. Pipkin IV fractures subclassified to OTA/AO 31C2 type with suprafoveal and posterior head impaction and older age should be counseled of high conversion risk with consideration for alternative management options. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVES: To determine patient, fracture, and construct related risk factors associated with nonunion of distal femur fractures. DESIGN: Retrospective cohort study. SETTING: Academic Level I trauma center. PARTICIPANTS: Patients 18 years and older presenting with OTA/AO 33A and 33C distal femur fractures from 2004 to 2020. A minimum follow-up of 6 months was required for inclusion. OTA/AO 33B and periprosthetic fractures were excluded, 438 patients met inclusion criteria for the study. MAIN OUTCOMES: The primary outcome of the study was fracture nonunion defined as a return to the OR for management of inadequate bony healing. Patient demographics, comorbidities, injury characteristics, fixation type, and construct variables were assessed for association with distal femur fracture nonunion. Secondary outcomes include conversion to total knee arthroplasty, surgical site infection, and other reoperation. RESULTS: The overall nonunion rate was 13.8% (61/438). The nonunion group was compared directly with the fracture union group for statistical analysis. There were no differences in age, sex, mechanism of injury, Injury Severity Score, and time to surgery between the groups. Lateral locked plating characteristics including length of plate, plate metallurgy, screw density, and working length were not significantly different between groups. Increased body mass index [odds ratio (OR), 1.05], chronic anemia (OR, 5.4), open fracture (OR, 3.74), and segmental bone loss (OR, 2.99) were independently associated with nonunion. Conversion to total knee arthroplasty (TKA) ( P = 0.005) and surgical site infection ( P < 0001) were significantly more common in the nonunion group. CONCLUSION: Segmental bone loss, open fractures, chronic anemia, and increasing body mass index are significant risk factors in the occurrence of distal femoral nonunion. Lateral locked plating characteristics did not seem to affect nonunion rates. Further investigation into the prevention of nonunion should focus on fracture fixation constructs and infection prevention. LEVEL OF EVIDENCE: Prognostic Level III.

RESUMO

A displaced medial tibial plateau fracture with central and lateral impaction, but an intact anterolateral cortical rim, is an uncommon variant of bicondylar tibial plateau fracture that presents a number of challenges. Without a lateral metaphyseal fracture line to work through, it is challenging to address central and lateral impaction. Previously published techniques for addressing this fracture pattern describe an intra-articular osteotomy of the lateral plateau to aid visualization and reduction, or use a posterolateral approach to the proximal tibia with or without an osteotomy of the proximal fibula. This study presents a technique which utilizes standard dual incision approaches and does not involve an intra-articular osteotomy of the lateral tibial plateau or a posterolateral approach. A case series was conducted evaluating radiographic and functional outcomes of 8 patients.

RESUMO

The purpose of this multicenter retrospective chart review was to describe demographics, fracture and wound characteristics, and treatments for foot and/or ankle fractures caused by gunshot wounds (GSWs) and identify factors that increase risk of infection in adults treated at 5 urban level 1 trauma centers in South and Midwest regions of the United States. A total of 244 patients sustained GSW-related fractures of the foot/ankle during 2007-2017, of whom 179 had ≥30 days of follow-up data after the initial injury. Most patients were male (95.1%; 232/244) with an average age of 31.2 years. On average, patients sustained 1.3 GSWs (range 1-5) to the foot/ankle. Most GSWs were categorized as low energy (85.1%; 171/201) and the majority (58.2%; 142/244) had retained bullet fragments. Antibiotics were administered at initial presentation to 78.7% (192/244) of patients and 41.8% (102/244) were managed operatively at the time of initial injury. Nerve injury, vascular injury, and infection were documented in, respectively, 8.6% (21/243), 6.6% (16/243), and 17.2% (42/244) of all cases. Multivariable analysis revealed that high-energy injuries and retained bullet fragments increased the risk of infection by 3-fold (odds ratio 3.09, 95% confidence interval 1.16-8.27, p = .025) and 3.5-fold (OR 3.48, 95% CI1.40-8.67; p = .008), respectively. Side of injury, primary injury region, and vascular injury were not significant predictors of infection risk. Further research should examine whether retained bullet fragments are directly associated with infection risk and support the development of guidelines regarding the management of patients with GSW-related fractures to the ankle/foot.

RESUMO

OBJECTIVE: To quantify preoperative blood loss in isolated acetabular fractures and identify any fracture or patient characteristics associated with increased blood loss or blood transfusion. DESIGN: Retrospective cohort study. SETTING: Two level 1 trauma centers. PATIENTS/PARTICIPANTS: All patients with operative, isolated acetabular fractures from January 2010 to December 2018. INTERVENTION: Operative management of an acetabular fracture. MAIN OUTCOME MEASUREMENTS: Volume of preoperative blood loss and transfusion rates associated with isolated acetabular fracture patterns. RESULTS: A total of 598 patients were included. The mean preoperative blood loss of all fractures was 1172.6 mL. The 3 fracture patterns with the greatest average preoperative blood loss were associated both column (1454.9 mL), T-type (1374.8 mL), and anterior column posterior hemitransverse fractures (1317.7 mL). The acetabular fracture pattern had a significant association with preoperative blood loss and preoperative transfusion. The timing from injury to surgery and body mass index were significantly associated with preoperative blood loss. CONCLUSIONS: In conclusion, operatively treated isolated acetabular fractures surprisingly lose an average of greater than 1 liter of blood in the preoperative setting. Surgeons must carefully assess patient's physiology, ensuring they are adequately resuscitated before surgery and remain aware that increasing body mass index is associated with increased preoperative blood loss. However, as patients await surgery, unreduced acetabular fractures continue to contribute to ongoing blood loss beyond the first 24 hours from injury. We believe the best hemostasis after initial resuscitation is provided by surgical reduction and fixation, and we recommend a continued early surgical intervention to prevent continued bleeding from fracture surfaces. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVES: To evaluate the effects of prophylactic piperacillin-tazobactam (PT) on inpatient acute kidney injury (AKI) and fracture-related infection (FRI) in patients with open fractures. SETTING: The study was conducted at a Level 1 trauma center. PATIENTS: We reviewed 358 Gustilo-Anderson type II and III open fractures at our institution from January 2013 to December 2017. INTERVENTION: Administration of PT (the PT group) or antibiotics other than PT (the historical control group) during the first 48 hours of arrival for open fracture antibiotic prophylaxis. MAIN OUTCOME MEASUREMENTS: The main outcome measurements were rates of inpatient AKI and FRI within six months after definitive fixation. RESULTS: There were 176 patients in the PT group and 182 patients in the historical control group. The PT group had worse American Society of Anesthesiologists class ( P = 0.004) and injury severity scores ( P < 0.001), a higher average number of debridements before closure/coverage ( P = 0.043), and higher rates of gross soil contamination ( P = 0.049) and staged procedures ( P = 0.008) compared with the historical control group.There was no difference in the rate of AKI between the PT and historical control groups (5.7% vs. 2.7%, P = 0.166) nor when stratified by Gustilo-Anderson fracture classification (type II: 5.8% vs. 3.6%, P = 0.702; type III: 5.6% vs. 2.0%, P = 0.283). There was no significant difference in the rate of FRI between the PT and historical control groups (23.6% vs. 19.6%, P = 0.469). CONCLUSION: The use of PT in prophylactic antimicrobial treatment in patients with Gustilo-Anderson type II and III open fractures does not increase the rate of AKI or FRI. We believe PT can be used as an effective monotherapy in these patients without an increased risk of renal injury, but future investigations are necessary. LEVEL OF EVIDENCE: Therapeutic Level III.
