    Abstract Anticoagulation use is common in elderly patients presenting with hip fractures and has been shown to delay time to surgery (TTS). Delays in operative treatment have been associated with worse outcomes in hip fracture patients. Direct oral anticoagulants (DOACs) comprise a steadily increasing proportion of all oral anticoagulation. Currently, no clear guidelines exist for perioperative management of hip fracture patients taking DOACs. DOAC use is associated with increased TTS, with delays frequently greater than 48 h from hospital presentation. Increased mortality has not been widely demonstrated in DOAC patients, despite increased TTS. Timing of surgery was not found to be associated with increased risk of transfusion or bleeding. Early surgery appears to be safe in patients taking DOACs presenting with a hip fracture, but is not currently widely accepted due to factors such as site-specific anesthesiologic protocols that periodically delay surgery. Direct oral anticoagulant use should not routinely delay surgical treatment in hip fracture patients. Surgical strategies to limit blood loss should be considered and include efficient surgical fixation, topical application of hemostatic agents, and the use of intra-operative cell salvage. Anesthesiologic strategies have utility in minimizing risk and a collaborative effort to minimize blood loss should be undertaken by the surgeon and anesthesiologist. Anesthesia team interventions include considerations regarding positioning, regional anesthesia, permissive hypotension, avoidance of hypothermia, judicious administration of blood products, and the use of systemic hemostatic agents.

    Abstract Diaphyseal clavicle fractures occur most frequently in adolescents (defined as ages 10 to 19 years by the World Health Organization). Multiple prospective comparative studies exist in the adult literature, whereas studies focusing on adolescents are limited. Given the notable differences in healing potential between pediatric, adolescent, and adult diaphyseal clavicle fractures, treatment algorithms tailored specifically to children, adolescents, and adults are required. In the past two decades, there has been a dramatic rise in surgical fixation of adolescent diaphyseal clavicle fractures, largely influenced by adult literature. The remodeling potential of the clavicle throughout adolescence and into early adulthood exceeds that of the adult population. Furthermore, prospective outcomes studies of displaced diaphyseal clavicle fractures have demonstrated that, when compared with surgical management, nonsurgical management portends equivalent functional outcomes but a nearly four times greater rate of complications. Even those injuries with comminution and notable shortening, nonsurgical treatment yields good functional outcomes, high rates of return to sport, and low incidence of complications, such as nonunion, symptomatic malunion, and refracture. In rare cases of unsatisfactory nonsurgical treatment, secondary surgical fixation most often results in union and good functional outcomes.

    Abstract Background: Industry funding and corporate sponsorship have played a significant role in the advancement of orthopaedic research and technology. However, this relationship raises concerns for how industry association may bias research findings and influence clinical practice.
    Purpose: To determine whether industry affiliation plays a role in the outcomes of randomized controlled trials (RCTs) investigating platelet-rich plasma (PRP).
    Study design: Meta-analysis; Level of evidence, 2.
    Methods: A search of the PubMed, Cochrane, and MEDLINE databases for RCTs published between 2011 and the present comparing PRP versus hyaluronic acid, corticosteroid, or placebo for the treatment of knee osteoarthritis was performed. To determine industry affiliation, the conflict of interest, funding, and disclosure sections of publications were assessed, and all authors were assessed through the American Academy of Orthopaedic Surgeons disclosure database and the Centers for Medicare & Medicaid Services open payments database. Studies were classified as industry affiliated (IA) or non-industry affiliated (NIA). The outcomes of each study were rated as favorable, analogous, or unfavorable according to predefined criteria.
    Results: A total of 37 studies (6 IA and 31 NIA) were available for analysis. Overall, 19 studies (51.4%) reported PRP as favorable compared with other treatment options, while 18 studies (48.6%) showed no significant differences between PRP and other treatment methods. There was no significant difference in qualitative conclusions between the IA and NIA groups, with the IA group having 3 favorable studies and 3 analogous studies and the NIA group having 16 favorable studies and 15 analogous studies (
    Conclusion: The results of this study demonstrated that qualitative conclusions and outcome scores were found to not be associated with industry affiliation. Although the results of this study suggest that there is no influence of industry involvement on RCTs examining PRP, it is still necessary to carefully evaluate pertinent commercial affiliations when reviewing recommendations from studies before adopting new treatment approaches, such as the use of PRP for knee osteoarthritis.

    Abstract Objectives: The objective of this study was to define the danger zone at which the anterior tibial artery (ATA) is at risk during anterolateral plating of the distal tibia using a novel 3D computed tomography angiography (CTA) modeling technique.
    Methods: 116 patients (232 lower extremities) who underwent lower extremity CTAs between April 2020 and April 2022 were identified. Those with lower extremity trauma, evidence of a previously healed tibial fracture, or poor visualization of the ATA were excluded. The remaining 150 lower extremities (92 patients) were modeled with an anterolateral distal tibia plate using Sectra IDS7 software. The distance of the ATA from bony landmarks was measured perpendicular to the level at which the vessel intersected the plate.
    Results: The ATA intersected the plate proximally at a mean distance of 10.5 cm (95% confidence intervals, 10.2-10.9) and at a mean distance of 4.6 cm (95% confidence intervals, 4.4-4.9) distally from the central tibial plafond. The ATA intersected with the plate as far distal as hole number 1 and as proximal as hole 14 of the plate. The greatest injury risk was associated with plate holes 3-8. In this region, the artery was at risk in 46-99 percent of specimens.
    Conclusions: The ATA is at risk when screws are placed percutaneously in an anterolateral distal tibia plate. The artery can be as close as 4.4 cm and as far as 10.9 cm proximal to the tibial plafond when crossing the plate, correlating to a risk of injury to the ATA at plate holes 1 through 14.

    Abstract Traumatic native hip dislocations require prompt reduction of the dislocation to limit the risk of avascular necrosis and resultant hip arthrosis. Although closed reduction under sedation is frequently attempted, there is minimal evidence about which sedative agent is most safe and effective. The goal of this study was to compare the efficacy of propofol vs combination fentanyl/midazolam for closed reduction under sedation of traumatic native hip dislocations. This was a single-center retrospective review. The main outcome measures were the rate of successful closed reduction with propofol vs combination fentanyl/midazolam and time from the start of sedation to radiographic evidence of reduction. Fifty-four patients with traumatic native hip dislocations were identified. Closed reduction under sedation with propofol was successful in 11 of 14 attempts compared with 4 of 11 attempts with combination fentanyl/midazolam (

    Abstract Case: A 28-year-old woman with an infected proximal femur nonunion was treated with an antibiotic-coated intramedullary nail. Shortly after discharge, the patient presented to the emergency department and was readmitted with a morbilliform rash sparing the left lower extremity. She became hemodynamically unstable, despite cessation of intravenous antibiotics, requiring transfer to the intensive care unit and urgent removal of her antibiotic nail. She improved after surgery, and biopsy results from the rash confirmed acute generalized examthematous pustulosis.
    Conclusion: Acute generalized exanthematous pustulosis is a rare, dermatologic crisis that can be precipitated by antibiotics, even in the form of antibiotic cement.

This was a retrospective study of 331 spine surgery patients at UCSD conducted during 1 March 2019–31 May 2019 (pre-COVID-19) and 1 March 2020–31 May 2020 (first COVID-19 surge). All variables were collected through RedCap and compared between pre- and during-COVID groups. There were no significant differences in patient demographics, operating room duration, and skin-to-skin time. However, length of stay was 4.7 days shorter during COVID-19 ( p = 0.03) and more cases were classified as ‘urgent’ ( p = 0.04). Preoperative pain scores did not differ between groups ( p = 0.51). However, pain levels at discharge were significantly higher during COVID ( p = 0.04) and trended towards remaining higher in the short- ( p = 0.05) but not long-term ( p = 0.17) after surgery. There was no significant difference in the number of post-operative complications, but there was an increase in the use of the emergency room and telemedicine to address complications when they arose. Overall, the pandemic resulted in a greater proportion of ‘urgent’ spine surgery cases and shorter length of hospital stay. Pain levels upon discharge and at short-term timepoints were higher following surgery but did not persist in the long term.

    Abstract Introduction: The inability to mobilize after surgical intervention for hip fractures in the elderly is established as a risk factor for greater morbidity and mortality. Previous studies have evaluated the association between the timing and distance of ambulation in the postoperative acute care phase with postoperative complications. The purpose of this study was to evaluate the association between ambulatory distance in the acute postoperative setting and ambulatory capacity at 3 months.
    Methods: Patients aged 65 and older who were ambulatory at baseline and underwent surgical intervention for hip fractures from 2014 to 2019 were retrospectively reviewed. Consistent with previous literature, patients were divided into two groups: those who were able to ambulate 5 feet within 72 hours after surgical fixation (early ambulatory) and those who were not (minimally ambulatory).
    Results: One hundred seventy patients (84 early ambulatory and 86 minimally ambulatory) were available for analysis. Using a multivariable ordinal logistic regression model, variables found to be statistically significant predictors of ambulatory status at 3 months were the ability to ambulate five feet in 72 hours (P < 0.0001), ambulatory distance at discharge (P = 0.012), and time from presentation to surgery (P = 0.039). Patients who were able to ambulate 5 feet within 72 hours had 9 times the odds of being independent ambulators rather than a lower ambulatory class (cane, walker, and nonambulatory). Pertrochanteric fractures were less likely than femoral neck fractures to independently ambulate at 3 months (17.2% vs. 42.3%; P = 0.0006).
    Discussion: Ambulating 5 feet within 72 hours after hip fracture surgery is associated with an increased likelihood of independent ambulation at 3 months postoperatively. This simple and clear goal may be used to help enhance postoperative mobility and independence while providing a metric to guide therapy and help counsel patients and families.
