Background: Heterotopic ossification around the elbow can result in pain, loss of motion, and impaired function. We hypothesized that a single dose of radiation therapy could be administered safely and acutely after elbow trauma, could decrease the number of elbows that would require surgical excision of heterotopic ossification, and might improve clinical results.Methods: A prospective randomized study was conducted at three medical centers. Patients with an intra-articular distal humeral fracture or a fracture-dislocation of the elbow with proximal radial and/or ulnar fractures were enrolled. Patients were randomized to receive either single-fraction radiation therapy of 700 cGy immediately postoperatively (within seventy-two hours) or nothing (the control group). Clinical and radiographic assessment was performed at six weeks, three months, and six months postoperatively. All adverse events and complications were documented prospectively.Results: This study was terminated prior to completion because of an unacceptably high number of adverse events reported in the treatment group. Data were available on forty-five of the forty-eight patients enrolled in this study. When the rate of complications was investigated, a significant difference was detected in the frequency of nonunion between the groups. Of the nine patients who had a nonunion, eight were in the treatment group. The nonunion rate was 38% (eight) of twenty-one patients in the treatment group, which was significantly different from the rate of 4% (one) of twenty-four patients in the control group (p = 0.007). There were no significant differences between the groups with regard to the prevalence of heterotopic ossification, postoperative range of motion, or Mayo Elbow Performance Score noted at the time of study termination.Conclusions: This study demonstrated that postoperative single-fraction radiation therapy, when used acutely after elbow trauma for prophylaxis against heterotopic ossification, may play a role in increasing the rate of nonunion at the site of the fracture or an olecranon osteotomy. The clinical efficacy of radiation therapy could not be determined on the basis of the sample size. Further research is needed to determine the role of limited-field radiation for prophylaxis against heterotopic ossification after elbow trauma. [ABSTRACT FROM AUTHOR]

Objectives: To determine whether the timing of acetabular fracture fixation through an anterior approach influences estimated and calculated perioperative blood loss., Design: Retrospective cohort study., Setting: Level 1 trauma center from 2013 to 2021., Patient Selection Criteria: Patients aged ≥18 years treated with acetabular fracture fixation through an anterior-based approach., Outcome Measures and Comparisons: The primary outcome was calculated blood loss (CBL). Secondary outcomes were estimated blood loss reported by surgeon and anesthesia, and blood transfusion requirements. Comparisons of blood loss were made at discrete postinjury time thresholds (24, 36, and 48 hours) and on a continuous basis., Results: One hundred eight patients were studied. The mean age was 65 years, and 73% of patients were male. Earlier fixation of acetabular fractures resulted in greater CBL and estimated blood loss (surgeon and anesthesia) compared with later fixation when analyzed on a continuum and at specific time points (24, 36, and 48 hours). Mean CBL in patients treated earlier (<48 hours, 2539 ± 1194 mL) was significantly greater than those treated later (≥48 hours, 1625 ± 909 mL; P < 0.001). Fracture repair before 48 hours postinjury was associated with a 3 times greater risk of >2000 mL of CBL ( P = 0.006). This did not result in differences in transfusion rates between groups at 24 hours ( P = 0.518), 36 hours ( P = 1.000), or 48 hours ( P = 0.779)., Conclusions: Delaying fixation of acetabular fractures treated through an anterior approach for 48 hours postinjury may significantly reduce perioperative blood loss., Level of Evidence: Prognostic Level III.

Background: Studies evaluating surgical-site infection have had conflicting results with respect to the use of alcohol solutions containing iodine povacrylex or chlorhexidine gluconate as skin antisepsis before surgery to repair a fractured limb (i.e., an extremity fracture)., Methods: In a cluster-randomized, crossover trial at 25 hospitals in the United States and Canada, we randomly assigned hospitals to use a solution of 0.7% iodine povacrylex in 74% isopropyl alcohol (iodine group) or 2% chlorhexidine gluconate in 70% isopropyl alcohol (chlorhexidine group) as preoperative antisepsis for surgical procedures to repair extremity fractures. Every 2 months, the hospitals alternated interventions. Separate populations of patients with either open or closed fractures were enrolled and included in the analysis. The primary outcome was surgical-site infection, which included superficial incisional infection within 30 days or deep incisional or organ-space infection within 90 days. The secondary outcome was unplanned reoperation for fracture-healing complications., Results: A total of 6785 patients with a closed fracture and 1700 patients with an open fracture were included in the trial. In the closed-fracture population, surgical-site infection occurred in 77 patients (2.4%) in the iodine group and in 108 patients (3.3%) in the chlorhexidine group (odds ratio, 0.74; 95% confidence interval [CI], 0.55 to 1.00; P = 0.049). In the open-fracture population, surgical-site infection occurred in 54 patients (6.5%) in the iodine group and in 60 patients (7.3%) in the chlorhexidine group (odd ratio, 0.86; 95% CI, 0.58 to 1.27; P = 0.45). The frequencies of unplanned reoperation, 1-year outcomes, and serious adverse events were similar in the two groups., Conclusions: Among patients with closed extremity fractures, skin antisepsis with iodine povacrylex in alcohol resulted in fewer surgical-site infections than antisepsis with chlorhexidine gluconate in alcohol. In patients with open fractures, the results were similar in the two groups.

Objectives: To evaluate the rate of reoperation in patients without sagittal plane malalignment who underwent percutaneous screw fixation of a valgus-impacted femoral neck fracture., Design: Retrospective case series., Setting: Two Level 1 academic trauma centers., Patients and Intervention: Two hundred seven patients >50 years of age with valgus-impacted femoral neck fractures treated with at least 3 large-diameter (>6.5 mm) cancellous screws from 2013 to 2019. Patients were excluded if there was a sagittal plane fracture deformity., Main Outcome Measurements: The primary outcome was reoperation. Secondary outcomes considered "major complications" included: avascular necrosis, varus collapse or implant cutout, nonunion, deep infection, and hematoma requiring reoperation. Surgical fixation strategies (screw configuration, aim) and implant type (partial vs. fully threaded cancellous screws) were secondarily compared., Results: Average patient age was 77 years, and median clinical follow-up was 658 days. Thirty-one patients (15%) required reoperation, and the major complication rate was 17.3% (36 complications in 33 patients). Logistic regression analysis demonstrated a higher risk of reoperation with constructs consisting of all partially threaded screws (17.0%) compared with the use of at least 1 fully threaded screw (7.5%) when an inverted triangle configuration was used (odds ratio, 2.50; 95% CI, 0.81-7.77)., Conclusions: This study demonstrated a relatively high rate of reoperation and major complications in patients with valgus-impacted femoral neck fractures without sagittal malalignment treated with in situ percutaneous screw fixation., Level of Evidence: Therapeutic Level IV.

Objectives: To determine if the use of Peripheral Nerve Block (PNB) versus Local Infiltration Analgesia (LIA) for hip fracture patients, affected opioid consumption in the early post-operative period., Design: Retrospective cohort study SETTING: Two level 1 trauma centers PATIENTS/INTERVENTION: 588 patients with surgically treated AO/OTA 31A and 31B fractures between February 2016-October 2017 were included. 415 (70.6%) received general anesthesia (GA) alone, 152 received GA plus perioperative PNB (25.9%), and 21 had GA plus LIA intra-operatively (3.6%). Median age was 82 years; predominantly female (67%) and AO/OTA 31A fractures (55.37%)., Main Outcome Measures: Morphine Milligram Equivalents (MME) at 24 and 48 hours postoperatively, length of stay (LOS) and the occurrence of any complication after surgery RESULTS: The PNB cohort was less likely to use any opioid than the GA group at 24 and 48 hours postoperatively (OR: 0.36, 95% CI: 0.22-0.61 and OR: 0.56, 95% CI: 0.35-0.89 respectively). LOS ≥ 10 days had 3.24 times the odds of 24- and 48-hour opioid administration compared to LOS ≤ 10 days (OR: 3.24, 95% CI 1.11-9.42; OR: 2.98, 95% CI 1.38-6.41, respectively). The most common complication was post-operative delirium, with PNB more likely to present with any complication compared to GA (OR= 1.88, 95% CI 1.09-3.26). There was no difference when comparing LIA to general anesthesia., Conclusions: Our findings suggest PNB for hip fracture can help limit the use of post-operative opioids with adequate pain relief. Regional analgesia does not seem to avoid complications such as delirium., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr. Hsu reports consultancy and speaker fees for Stryker, consultancy and speaker fees from Smith & Nephew speakers’ bureau, soeaker fees from Integra Lifesciences, and speaker fees from Depuy/Synthes., (Copyright © 2023 Elsevier Ltd.

Objectives: Surgical site infections in orthopaedic trauma are a significant problem with meaningful patient and health care system-level consequences. Direct application of antibiotics to the surgical field has many potential benefits in reducing surgical site infections. However, to date, the data regarding the local administration of antibiotics have been mixed. This study reports on the variability of prophylactic vancomycin powder use in orthopaedic trauma cases across 28 centers., Methods: Intrawound topical antibiotic powder use was prospectively collected within three multicenter fracture fixation trials. Fracture location, Gustilo classification, recruiting center, and surgeon information were collected. Differences in practice patterns across recruiting center and injury characteristics were tested using chi-square statistic and logistic regression. Additional stratified analyses by recruiting center and individual surgeon were performed., Results: A total of 4941 fractures were treated, and vancomycin powder was used in 1547 patients (31%) overall. Local administration of vancomycin powder was more frequent in open fractures 38.8% (738/1901) compared with closed fractures 26.6% (809/3040) ( P < 0.001). However, the severity of the open fracture type did not affect the rate at which vancomycin powder was used ( P = 0.11). Vancomycin powder use varied substantially across the clinical sites ( P < 0.001). At the surgeon level, 75.0% used vancomycin powder in less than one-quarter of their cases., Conclusions: Prophylactic intrawound vancomycin powder remains controversial with varied support throughout the literature. This study demonstrates wide variability in its use across institutions, fracture types, and surgeons. This study highlights the opportunity for increased practice standardization for infection prophylaxis interventions., Level of Evidence: Prognostic-III., (Copyright © 2023 The Authors.

Background: At the initiation of the COVID-19 pandemic, restrictions forced researchers to decide whether to continue their ongoing clinical trials. The PREPARE (Pragmatic Randomized Trial Evaluating Pre-Operative Alcohol Skin Solutions in Fractured Extremities) trial is a pragmatic cluster-randomized crossover trial in patients with open and closed fractures. PREPARE was enrolling over 200 participants per month at the initiation of the pandemic. We aim to describe how the COVID-19 research restrictions affected participant enrollment., Methods: The PREPARE protocol permitted telephone consent, however, sites were obtaining consent in-person. To continue enrollment after the initiation of the restrictions participating sites obtained ethics approval for telephone consent scripts and the waiver of a signature on the consent form. We recorded the number of sites that switched to telephone consent, paused enrollment, and the length of the pause. We used t-tests to compare the differences in monthly enrollment between July 2019 and November 2020., Results: All 19 sites quickly implement telephone consent. Fourteen out of nineteen (73.6%) sites paused enrollment due to COVID-19 restrictions. The median length of enrollment pause was 46.5 days (range, 7-121 days; interquartile range, 61 days). The months immediately following the implementation of restrictions had significantly lower enrollment., Conclusion: A pragmatic design allowed sites to quickly adapt their procedures for obtaining informed consent via telephone and allowed for minimal interruptions to enrollment during the pandemic., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 Published by Elsevier Inc.)

Summary: In current clinical practice, weight-bearing is typically restricted for up to 12 weeks after definitive fixation of lower extremity periarticular fractures. However, muscle atrophy resulting from restricting weight-bearing has a deleterious effect on bone healing and overall limb function. Antigravity treadmill therapy may improve recovery by allowing patients to safely load the limb during therapy, thereby reducing the negative consequences of prolonged non-weight-bearing while avoiding complications associated with premature return to full weight-bearing. This article describes a multicenter randomized controlled trial comparing outcomes after a 10-week antigravity treadmill therapy program versus standard of care in adult patients with periarticular fractures of the knee and distal tibia. The primary hypothesis is that, compared with patients receiving standard of care, patients receiving antigravity treadmill therapy will report better function 6 months after definitive treatment., Competing Interests: The authors report no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background: The effects of spinal anesthesia as compared with general anesthesia on the ability to walk in older adults undergoing surgery for hip fracture have not been well studied., Methods: We conducted a pragmatic, randomized superiority trial to evaluate spinal anesthesia as compared with general anesthesia in previously ambulatory patients 50 years of age or older who were undergoing surgery for hip fracture at 46 U.S. and Canadian hospitals. Patients were randomly assigned in a 1:1 ratio to receive spinal or general anesthesia. The primary outcome was a composite of death or an inability to walk approximately 10 ft (3 m) independently or with a walker or cane at 60 days after randomization. Secondary outcomes included death within 60 days, delirium, time to discharge, and ambulation at 60 days., Results: A total of 1600 patients were enrolled; 795 were assigned to receive spinal anesthesia and 805 to receive general anesthesia. The mean age was 78 years, and 67.0% of the patients were women. A total of 666 patients (83.8%) assigned to spinal anesthesia and 769 patients (95.5%) assigned to general anesthesia received their assigned anesthesia. Among patients in the modified intention-to-treat population for whom data were available, the composite primary outcome occurred in 132 of 712 patients (18.5%) in the spinal anesthesia group and 132 of 733 (18.0%) in the general anesthesia group (relative risk, 1.03; 95% confidence interval [CI], 0.84 to 1.27; P = 0.83). An inability to walk independently at 60 days was reported in 104 of 684 patients (15.2%) and 101 of 702 patients (14.4%), respectively (relative risk, 1.06; 95% CI, 0.82 to 1.36), and death within 60 days occurred in 30 of 768 (3.9%) and 32 of 784 (4.1%), respectively (relative risk, 0.97; 95% CI, 0.59 to 1.57). Delirium occurred in 130 of 633 patients (20.5%) in the spinal anesthesia group and in 124 of 629 (19.7%) in the general anesthesia group (relative risk, 1.04; 95% CI, 0.84 to 1.30)., Conclusions: Spinal anesthesia for hip-fracture surgery in older adults was not superior to general anesthesia with respect to survival and recovery of ambulation at 60 days. The incidence of postoperative delirium was similar with the two types of anesthesia.

Objective: Given the tremendous medical, social and financial costs of surgical site infections, the pressure to minimize these complications has been mounting. There remains a substantial gap in evidence-based practice for postoperative wound care after orthopaedic trauma surgery. The purpose of this study is to determine what standards are currently in practice for postoperative wound management., Methods: A 16-question web-based survey was published on the Orthopaedic Trauma Association website and disseminated to members through the association's quarterly email. The survey gathered data on postoperative wound care practices; specifically, when wound checks are performed, and when providers allow patients to get the incisions wet., Results: 102 Orthopaedic surgeons completed the survey. Ninety-one percent were trauma fellowship trained, and 95% worked at either a Level I (76%) or Level II (19%) trauma center. There were over 100 different proposed protocols captured by the survey. The majority of surgeons (54%) perform a wound check within the first three days after surgery. Additionally, half of surgeons (50%) do not permit patients to get their incisions wet until sutures and staples are removed., Conclusion: Wound care routines following surgical management of orthopaedic trauma injuries are highly variable. Diverse protocols are performed at the discretion of the treating surgeon without scientific basis. This study defines immense variability in one aspect of peri-operative care that could play an important role in surgical site infections and provides a foundation for future studies to explore the potential influence of standardized wound care routines on post-operative infections and wound healing., Competing Interests: Declaration of Competing Interests All authors have no personal or financial conflicts of interest to report related to the present study., (Copyright © 2021 Elsevier Ltd.

Importance: Despite the widespread use of systemic antibiotics to prevent infections in surgically treated patients with fracture, high rates of surgical site infection persist., Objective: To examine the effect of intrawound vancomycin powder in reducing deep surgical site infections., Design, Setting, and Participants: This open-label randomized clinical trial enrolled adult patients with an operatively treated tibial plateau or pilon fracture who met the criteria for a high risk of infection from January 1, 2015, through June 30, 2017, with 12 months of follow-up (final follow-up assessments completed in April 2018) at 36 US trauma centers., Interventions: A standard infection prevention protocol with (n = 481) or without (n = 499) 1000 mg of intrawound vancomycin powder., Main Outcomes and Measures: The primary outcome was a deep surgical site infection within 182 days of definitive fracture fixation. A post hoc comparison assessed the treatment effect on gram-positive and gram-negative-only infections. Other secondary outcomes included superficial surgical site infection, nonunion, and wound dehiscence., Results: The analysis included 980 patients (mean [SD] age, 45.7 [13.7] years; 617 [63.0%] male) with 91% of the expected person-time of follow-up for the primary outcome. Within 182 days, deep surgical site infection was observed in 29 of 481 patients in the treatment group and 46 of 499 patients in the control group. The time-to-event estimated probability of deep infection by 182 days was 6.4% in the treatment group and 9.8% in the control group (risk difference, -3.4%; 95% CI, -6.9% to 0.1%; P = .06). A post hoc analysis of the effect of treatment on gram-positive (risk difference, -3.7%; 95% CI, -6.7% to -0.8%; P = .02) and gram-negative-only (risk difference, 0.3%; 95% CI, -1.6% to 2.1%; P = .78) infections found that the effect of vancomycin powder was a result of its reduction in gram-positive infections., Conclusions and Relevance: Among patients with operatively treated tibial articular fractures at a high risk of infection, intrawound vancomycin powder at the time of definitive fracture fixation reduced the risk of a gram-positive deep surgical site infection, consistent with the activity of vancomycin., Trial Registration: ClinicalTrials.gov Identifier: NCT02227446.

Objectives: To determine the factors associated with successful union and eradication of infection in the setting of staged procedures to treat obviously infected nonunions of long bones. We hypothesize that patients with positive intraoperative cultures obtained at the time of definitive surgery for infected nonunions are more likely to have persistent nonunion than those with negative cultures., Design: Multicenter retrospective review., Setting: Eight academic Level 1 trauma centers., Patients/participants: Patients who underwent staged management for obviously infected nonunion of a long bone., Main Outcome Measurements: For each patient, initial fracture management, management of retained implants, number of debridements, grafting, bacteriology, antibiotic course, bone defect management, soft-tissue coverage, and definitive surgery performed were reviewed., Results: A total of 134 patients were treated with staged procedures for obviously infected nonunion of a long bone (mean age 49 years, 60% open fractures, and mean follow-up 22 months). During definitive procedures, 120 patients had intraoperative cultures taken with 43% having positive cultures. For culture-positive patients, 41 patients achieved eventual union and 10 had persistent nonunion. Of 69 culture-negative patients, 66 achieved eventual union and 3 had persistent nonunion. The number of patients with union versus persistent nonunion was statistically significant between culture-positive and culture-negative groups (P = 0.015)., Conclusions: Management of infected nonunion in long bones with staged treatments before definitive fixation are beneficial but ultimately less effective when performed in the setting of positive bacterial cultures at the time of definitive management., Level of Evidence: Prognostic Level III.

Engaging patients-defined broadly as individuals with lived experience of a given condition, family members, caregivers, and the organisations that represent them-as partners in research is a priority for policymakers, funders, and the public. Nonetheless, formal efforts to engage patients are absent from most studies, and models to support meaningful patient engagement in clinical anaesthesia research have not been previously described. Here, we review our experience in developing and implementing a multifaceted patient engagement strategy within the Regional Versus General Anesthesia for Promoting Independence After Hip Fracture (REGAIN) surgery trial, an ongoing randomised trial comparing spinal vs general anaesthesia for hip fracture surgery in 1600 older adults across 45 hospitals in the USA and Canada. This strategy engaged patients and their representatives at both the level of overall trial oversight and at the level of individual recruiting sites. Activities spanned a continuum ranging from events designed to elicit patients' input on key decisions to longitudinal collaborations that empowered patients to actively participate in decision-making related to trial design and management. Engagement activities were highly acceptable to participants and led to concrete changes in the design and conduct of the REGAIN trial. The REGAIN experience offers a model for future efforts to engage patients as partners in clinical anaesthesia research, and highlights potential opportunities for investigators to increase the relevance of anaesthesia studies by incorporating patient voices and perspectives into the research process., (Copyright © 2020 British Journal of Anaesthesia.

Importance: Numerous studies have demonstrated that long-term outcomes after orthopedic trauma are associated with psychosocial and behavioral health factors evident early in the patient's recovery. Little is known about how to identify clinically actionable subgroups within this population., Objectives: To examine whether risk and protective factors measured at 6 weeks after injury could classify individuals into risk clusters and evaluate whether these clusters explain variations in 12-month outcomes., Design, Setting, and Participants: A prospective observational study was conducted between July 16, 2013, and January 15, 2016, among 352 patients with severe orthopedic injuries at 6 US level I trauma centers. Statistical analysis was conducted from October 9, 2017, to July 13, 2018., Main Outcomes and Measures: At 6 weeks after discharge, patients completed standardized measures for 5 risk factors (pain intensity, depression, posttraumatic stress disorder, alcohol abuse, and tobacco use) and 4 protective factors (resilience, social support, self-efficacy for return to usual activity, and self-efficacy for managing the financial demands of recovery). Latent class analysis was used to classify participants into clusters, which were evaluated against measures of function, depression, posttraumatic stress disorder, and self-rated health collected at 12 months., Results: Among the 352 patients (121 women and 231 men; mean [SD] age, 37.6 [12.5] years), latent class analysis identified 6 distinct patient clusters as the optimal solution. For clinical use, these clusters can be collapsed into 4 groups, sorted from low risk and high protection (best) to high risk and low protection (worst). All outcomes worsened across the 4 clinical groupings. Bayesian analysis shows that the mean Short Musculoskeletal Function Assessment dysfunction scores at 12 months differed by 7.8 points (95% CI, 3.0-12.6) between the best and second groups, by 10.3 points (95% CI, 1.6-20.2) between the second and third groups, and by 18.4 points (95% CI, 7.7-28.0) between the third and worst groups., Conclusions and Relevance: This study demonstrates that during early recovery, patients with orthopedic trauma can be classified into risk and protective clusters that account for a substantial amount of the variance in 12-month functional and health outcomes. Early screening and classification may allow a personalized approach to postsurgical care that conserves resources and targets appropriate levels of care to more patients.

Previous research suggests that the care provided to trauma patients could be improved by including early screening and management of emotional distress and psychological comorbidity. The Trauma Collaborative Care (TCC) program, which is based on the principles of well-established models of collaborative care, was designed to address this gap in trauma center care. This article describes the TCC program and the design of a multicenter study to evaluate its effectiveness for improving patient outcomes after major, high-energy orthopaedic trauma at level 1 trauma centers. The TCC program was evaluated by comparing outcomes of patients treated at 6 intervention sites (n = 481) with 6 trauma centers where care was delivered as usual (control sites, n = 419). Compared with standard treatment alone, it is hypothesized that access to the TCC program plus standard treatment will result in lower rates of poor patient-reported function, depression, and posttraumatic stress disorder.

Traumatic injury frequently leads to an abrupt change in physical and psychological functioning; informal caregivers play a significant role in the recovery process in the hospital and at home. The purpose of this study was to describe the range of stressors and burdens experienced by orthopedic trauma family caregivers in the acute care setting, as well as responses and strategies employed. Qualitative, in-depth interviews were conducted in the hospital with 12 family caregivers of severely injured orthopedic trauma patients. Interviews were audiotaped, transcribed, and analyzed to identify the range of experiences and common themes. Data were organized into 4 categories: stressors and needs; barriers; resources; and response. Stressors and barriers included the confusion and turmoil of life in the hospital, exposure to tragedy, difficulty obtaining and understanding information, and a sense that the family was not considered an integral part of the care plan. Factors influencing caregiver coping included access to the patient, provider communication, caregiver internal and external resources, and the presence of staff assisting in negotiation of the complex and unfamiliar hospital system. Understanding the caregiver experience enables nursing providers to build trust and offer effective support and guidance; caregiver-centered systems of information from admission to discharge may facilitate adaptation and improved caregiving.

Tibia fracture is the most common type of long bone fracture, and intramedullary nailing is the preferred treatment. In open fractures, a provisional plate is often used to maintain reduction. It is unknown whether this practice increases the risk of infection or other complications. This study retrospectively compared patients who were treated at a level 1 trauma center with intramedullary nailing of an open tibia fracture. Patients who were included: (1) were 18 years or older; (2) were treated between January 1, 2005, and June 30, 2013; (3) had an open fracture of the tibia; and (4) were treated operatively with intramedullary nailing, with or without provisional plate fixation. Patient sex, history of diabetes, history of smoking, mechanism of injury, and side of injury were analyzed. Postoperative complications included infection, delayed union or non-union, compartment syndrome, and death. After the authors controlled for age, Gustilo-Anderson type, and AO/Orthopaedic Trauma Association classification, they found that provisional plate use did not significantly increase the risk of infection (adjusted odds ratio, 1.64; 95% confidence interval, 0.51-5.32; P=.41) or any other complications (adjusted odds ratio, 1.24; 95% confidence interval, 0.46-3.35; P=.67). In the subgroup of patients who had a provisional plate (n=35), removal of the plate did not significantly decrease the risk of infection (adjusted odds ratio, 0.43; 95% confidence interval, 0.07-2.69; P=.36) or other complications (adjusted odds ratio, 0.55; 95% confidence interval, 0.12-2.46; P=.44). In open tibia fractures treated with intramedullary nailing, provisional plate stabilization, a valuable reduction aid, did not increase the risk of infection or other complications. Because of the small subgroup size, however, definitive conclusions cannot be drawn about removal of these provisional plates.

Objectives: Locking plates are the predominant implants used for proximal humerus fractures. Despite a preponderance of good clinical outcomes, failures continue to occur. The purpose of this study was to investigate the failure mechanism of locked proximal humeral plate fixation and its relationship with bone density and screw length., Methods: Human cadaveric humeri were subjected to cyclic bending loads after an unstable 2-part fracture (Orthopedic Trauma Association classification 11 A-3) was created and stabilized with a locking proximal humeral plate. Acoustic emission (AE) sensors were mounted on the specimens to detect fracture displacement and generation of microcracks. The data were analyzed to evaluate construct failure., Results: Eight of 10 locking plate constructs in cadaver specimens failed in varus collapse. The primary influences on failure were cancellous bone density and cancellous bone screw length. AE monitoring demonstrated patterns of microcrack progression, predominantly along the inferior screws. The progression trends according to AE were similar to their respective actuator displacement versus time curves., Conclusions: Cancellous bone density and total cancellous screw depth penetration seem to be critical variables. Although the patients' bone density cannot be controlled, surgeons may decrease the risk of failure by maximizing the length of the screws within the cancellous bone. Analysis of microcrack formation revealed that failures begin at the midportion and tips of the inferior screws and at the bone-plate interface of the inferior screws.

Background: The development of a deep wound infection in the presence of hardware after open reduction and internal fixation presents a clinical dilemma, and there is scant literature to aid in decision-making. The purpose of the present study was to determine the prevalence of osseous union with maintenance of hardware after the development of postoperative infection within six weeks after internal fixation of a fracture., Methods: The present study included 121 patients from three level-I trauma centers, retrospectively identified from billing and trauma registries, in whom 123 postoperative wound infections with positive intraoperative cultures had developed within six weeks after internal fixation of acute fractures. The incidence of fracture union without hardware removal was calculated, and the parameters that predicted success or failure were evaluated., Results: Eighty-six patients (eighty-seven fractures; 71%) had fracture union with operative débridement, retention of hardware, and culture-specific antibiotic treatment and suppression. Predictors of treatment failure were open fracture (p = 0.03) and the presence of an intramedullary nail (p = 0.01). Several variables were not significant but trended toward an association with failure, including smoking, infection with Pseudomonas species, and involvement of the femur, tibia, ankle, or foot., Conclusions: Deep infection after internal fixation of a fracture can be treated successfully with operative débridement, antibiotic suppression, and retention of hardware until fracture union occurs. These results may be improved by patient selection based on certain risk factors and the specific bacteria and implants involved.

In a retrospective study of 476 surgical orthopedic trauma patients, we compared postoperative infection rates between individuals seropositive for the human immunodeficiency virus (HIV) and with no associated clinical symptoms with HIV-seronegative patients. Overall, the surgical postoperative infection rate was 16.7% in seropositive patients and 5.4% in the seronegative group (Chi-square, p = 0.035). When open fractures were considered separately, the seropositive group had a 55.6% infection rate compared with 11.3% in the seronegative group (Fisher's exact test, p = 0.004). Similarly, seropositive patients also had significantly increased rates of postoperative non-wound infections and complications (Chi-square p < 0.001). Asymptomatic HIV-seropositive orthopedic trauma patients are at significantly higher risk for postoperative infections than their seronegative counterparts. For HIV-seropositive patients with open fractures, this risk is especially pronounced.
