    Abstract Objective: To investigate current practices among orthopaedic trauma surgeons in treating geriatric distal femur fractures and evaluate current postoperative weight-bearing recommendations.
    Methods: A 26-question survey was emailed to Major Extremity Trauma Research Consortium surgeon members to characterize current practice with different fixation methods for distal femur fractures and the surgeon-directed postoperative weight-bearing recommendations for each approach.
    Results: Surveys were completed by 123 orthopaedic trauma surgeons with a response rate of 37% (123/332). Retrograde intramedullary nailing (IMN) was commonly performed by 88% of surgeons, and lateral locked plate was commonly performed by 74% of surgeons. Retrograde IMN with a lateral plate was commonly performed by 51% of surgeons. Dual femoral plating was commonly performed by 18% of surgeons and sometimes performed by 39% of surgeons. Surgeons were significantly more likely to allow immediate postoperative weight-bearing for retrograde IMN (
    Conclusion: A variety of implants are commonly used to treat geriatric distal femur fractures. Patients with distal femur fracture commonly have weight-bearing restrictions in the immediate postoperative period. A large proportion of orthopaedic trauma surgeons have clinical equipoise for an RCT to investigate the impact of surgical construct and weight-bearing on geriatric distal femur fracture patient recovery.

    Abstract Background: Several factors are thought to contribute to posttraumatic osteoarthritis (PTOA) development, including the posttraumatic inflammatory response. The purpose of this study was to compare 2 injuries at the same joint with a different severity and prognosis. This study compared the intra-articular inflammatory response after rotational ankle fracture (lower energy and less PTOA) with tibial plafond fracture (higher energy and more PTOA).
    Methods: This prospective comparative study was conducted at a level 1 trauma center between 2014-2019. Patients between 18 and 60 years of age with acute ankle or tibial plafond fractures were enrolled. Patients with preexisting ankle OA, autoimmune disease, additional injury, or open fractures were excluded. Synovial fluid aspirations were obtained within 24 hours of injury. The concentrations of interleukin (IL)-1β, IL-1 receptor antagonist (IL-1RA), IL-6, IL-8, and IL-10 and matrix metalloproteinase (MMP)-1, MMP-3, and MMP-13 were quantified.
    Results: Aspiration were obtained from 29 plafond fractures and 36 ankle fractures. Mean age was 43 years, and patients were predominately female (64%). Age, gender, and comorbidities did not vary between cohorts. Of the plafond fractures, 13 were 43-B and 16 were 43-C injuries. Ankle fractures were predominately 44-B injuries, and 15 ankle fracture had articular impaction. IL-10, IL-1β, IL-6, IL-8, MMP-1, MMP-3, and MMP-13 were all significantly higher in acute plafond fractures as compared to acute ankle fractures.
    Conclusion: This study compared articular inflammatory marker profiles after fractures of different severities. Several cytokines were elevated in plafond fractures as compared to ankle fractures, suggesting a greater inflammatory response with plafond fractures. Given the difference in prognosis for and higher rate of PTOA after plafond fractures, these data strengthen the case that postinjury inflammatory response plays a role in PTOA development. Given that the postinjury inflammatory response is one of the few modifiable variables of these injuries, future research in this area remains important.
    Level of evidence: Level II, prospective.

    Abstract Background: Chronic preconception paternal alcohol use adversely modifies the sperm epigenome, inducing fetoplacental and craniofacial growth defects in the offspring of exposed males. A crucial outstanding question in the field of paternal epigenetic inheritance concerns the resilience of the male germline and its capacity to recover and correct sperm-inherited epigenetic errors after stressor withdrawal.
    Objectives: We set out to determine if measures of the sperm-inherited epigenetic program revert to match the control treatment 1 month after withdrawing the daily alcohol treatments.
    Materials and methods: Using a voluntary access model, we exposed C57BL/6J males to 6% or 10% alcohol for 10 weeks, withdrew the alcohol treatments for 4 weeks, and used RNA sequencing to examine gene expression patterns in the caput section of the epididymis. We then compared the abundance of sperm small RNA species between treatments.
    Results: In the caput section of the epididymis, chronic alcohol exposure induced changes in the transcriptional control of genetic pathways related to the mitochondrial function, oxidative phosphorylation, and the generalized stress response (EIF2 signaling). Subsequent analysis identified region-specific, alcohol-induced changes in mitochondrial DNA copy number across the epididymis, which correlated with increases in the mitochondrial DNA content of alcohol-exposed sperm. Notably, in the corpus section of the epididymis, increases in mitochondrial DNA copy number persisted 1 month after alcohol cessation. Analysis of sperm noncoding RNAs between control and alcohol-exposed males 1 month after alcohol withdrawal revealed a ∼100-fold increase in mir-196a, a microRNA induced as part of the nuclear factor erythroid 2-related factor 2 (Nrf2)-driven cellular antioxidant response.
    Discussion and conclusion: Our data reveal that alcohol-induced epididymal mitochondrial dysfunction and differences in sperm noncoding RNA content persist after alcohol withdrawal. Further, differences in mir-196a and sperm mitochondrial DNA copy number may serve as viable biomarkers of adverse alterations in the sperm-inherited epigenetic program.

    Abstract Autologous bone graft remains the only clinically available source of graft material with osteogenic, osteoinductive, and osteoconductive properties. Although iliac crest autologous bone graft has long served as the benchmark, reamed autogenous bone graft offers several advantages. Reamed autograft has a biochemical and cellular profile that is at least equivalent, and perhaps superior, to that of iliac crest autograft. In addition, larger volumes of reamed autograft can be obtained via less-invasive techniques, giving surgeons an accessible source of mesenchymal stem cells that can be reliably and repeatedly harvested. Early clinical experience involving reamed autogenous bone graft in the management of nonunion, bone defects, and arthrodesis has been encouraging and has demonstrated the necessary properties to warrant regular consideration of reamed graft for these applications.

    Abstract Background: Bacterial cancer therapy was first trialled in patients at the end of the nineteenth century. More recently, tumour-targeting bacteria have been harnessed to deliver plasmid-expressed therapeutic interfering RNA to a range of solid tumours. A major limitation to clinical translation of this is the short-term nature of RNA interference in vivo due to plasmid instability. To overcome this, we sought to develop tumour-targeting attenuated bacteria that stably express shRNA by virtue of integration of an expression cassette within the bacterial chromosome and demonstrate therapeutic efficacy in vitro and in vivo.
    Results: The attenuated tumour targeting Salmonella typhimurium SL7207 strain was modified to carry chromosomally integrated shRNA expression cassettes at the xylA locus. The colorectal cancer cell lines SW480, HCT116 and breast cancer cell line MCF7 were used to demonstrate the ability of these modified strains to perform intracellular infection and deliver effective RNA and protein knockdown of the target gene c-Myc. In vivo therapeutic efficacy was demonstrated using the Lgr5creER
    Conclusions: In summary we have demonstrated that tumour tropic bacteria can be modified to safely deliver therapeutic levels of gene knockdown. This technology has the potential to specifically target primary and secondary solid tumours with personalised therapeutic payloads, providing new multi-cancer detection and treatment options with minimal off-target effects. Further understanding of the tropism mechanisms and impact on host immunity and microbiome is required to progress to clinical translation.

    Abstract Background: Obtaining insurance approval is a necessary component of healthcare in the United States and denials of these claims have been estimated to result in a loss of 3% to 5% of revenue.
    Objective: Examine the trends in insurance denials for rhinological procedures.
    Methods: A retrospective review of deidentified financial data of patients who were treated by participating physicians across 3 institutions from January 1, 2021, to June 30, 2023. The data was queried for rhinological and non-rhinological procedures via CPT codes. Cumulative insurance denials were calculated and stratified by procedure and insurance type. Write-offs were dollar amounts associated with final denials.
    Results: A sample of 102,984 procedures and visits revealed a final denial rate between 2.2% and 2.9% across institutions (
    Conclusion: Final denial rates of rhinology procedures ranged between 2% and 3%. Common procedures such as nasal endoscopy and nasal debridement are among the highest written-off procedures. Insurance denials can lead to notable revenue loss. Rhinology practices must continue to remain knowledgeable of the changes and effects of insurance reimbursement on their practice.

    Abstract Introduction: The natural history of diaphyseal tibial butterfly fragments is poorly documented. Numerous studies have analyzed risk factors for nonunions in the tibial shaft with known factors including Gustilo classification, ASA class, and cortical contact. However, the healing potential and ideal management of nonsegmental butterfly fragments in this setting remains unknown. The aim of this study was to determine the nonunion rate of diaphyseal tibial fractures with a butterfly fragment.
    Methods: A performed a retrospective review of patients at a single academic Level 1 Trauma Center from 2000-2020 who underwent intramedullary nailing of tibial shaft fractures. Those with non-segmental butterfly fragments (OTA/AO: 42-B) and minimum 12 month follow up were included. Morphologic measurements of butterfly fragments were performed to measure location, size, and displacement, and mRust scores at final follow up were calculated. Outcome measures were surgery to promote union, and mRust scores.
    Results: A total of 99 patients were included with 21 patients requiring revision surgery to promote union. Thirty six patients had open fractures and 77% of patients were male with a mean age of 34 (range: 12-80). Average follow up was 19 months (3 months - 12 years). The most common location of the butterfly fragment was the anterior cortex (42%), with a mean length of 7.8cm (SD: 3.3) and width of 1.8cm (SD: 0.5cm). At final follow-up 37% of fractures had persistent lucency without callus at the site of the butterfly while only 31% of fractures had remodeled cortex. Average time to complete healing was 13.3 months. Open fractures with butterfly fragments were more likely to go on to nonunion than closed (44% vs 9.2%, p=<0.001). The length of the butterfly fragment was not different between the union and nonunion groups (7.7 vs 7.5, P=0.42).
    Conclusions: Open tibial shaft fractures with a butterfly fragment have a high risk of nonunion. Further research may seek to determine if adjunct treatment of butterfly fragments (ie inter-fragmentary compression) in the acute setting could improve healing rates.
