Orthopaedic surgeons are partly responsible for this, but there is a wide variation of prescription practices within the specialty with no established guidelines. Excessive opiate prescription is associated with the development of addiction, increased risk of hip fracture, nonunion, and lethal overdose. Furthermore, there is growing evidence that increased opiate use does not correlate with pain control as strongly as psychosocial variables, and that pharmacologic alternatives may be equally effective in reducing postoperative pain. Methods: This will be a prospective study with two parts, each lasting about 6 months. The first part will quantify the baseline narcotic prescription habits of three orthopaedic trauma surgeons in the operative or nonoperative treatment of adult patients with isolated extremity trauma. Patients with a history of mental illness and chronic narcotic use or substance abuse will be excluded. Visual Analog Pain scores and opiate use in morphine equivalents will be collected on standardized forms at each postoperative visit. These data will be used to formulate new prescription guidelines that will then be implemented for six months and assessed with the same forms.Results: Pending https://doi.org/10.32873/unmc.dc.gmerj.1.1.080Comparison of Post-Operative Outcomes of Ciprofloxacin Otic Suspension versus Ciprofloxacin- Dexamethasone Otic Drops in Myringotomy with Tube PlacementAndrew W Logeman, Daniel V Arkfeld, Jayme R Dowdall, Dwight T JonesMentor: Dwight T JonesProgram: Otolaryngology Head and Neck SurgeryBackground and Objectives: Myringotomy with tubes is the most common procedure performed by Otolaryngologists. There is no standard of care regarding post-operative medication use. The objective of this study was to compare post-operative complications including otorrhea, extrusion, and obstruction between the two medications.Methods: A retrospective chart review was performed on children who underwent myringotomy with tube placement from February 2016 to February 2017 under a single surgeon at a single institution. Each ear received either ciprofloxacin-dexamethasone otic drops (CDOD) or ciprofloxacin otic suspension (COS). Statistical analysis was used to compare the complication rates between the two groups depending on middle ear status at the time of surgery.Results: 210 total patients identified, with 245 ears receiving CDOD and 99 receiving COS. For dry and mucoid middle ears at the time of surgery, there was no statistical difference between the use of CDOD and COS when assessing for post-operative complications. For serous middle ears, 2% of CDOD ears and 12% of COS ears were obstructed with p=0.0176. Additionally, 2% of CDOD ears and 22% COS ears had otorrhea with p=0.0001. There was no difference in tube extrusion in serous ears.Conclusion: No differences in post-operative complications were appreciated for mucoid or dry ears. Serous ears showed a significant increase in post-operative otorrhea and obstruction in COS compared to CDOD. CDOD should be used in serous ears. https://doi.org/10.32873/unmc.dc.gmerj.1.1.081Gender Difference in Glenoid RemodelingKent Rinehart, Matt Teusink, Chris Peters, AnnZajicekMentor: Matt TeusinkProgram: Orthopaedic SurgeryIntroduction: The purpose of this study is to compare glenoid morphology and wear patterns between male and female patients with primary shoulder osteoarthritis. Methods: A retrospective review of all patients who underwent an anatomic total shoulder arthroplasty by a single surgeon (MJT) for the diagnosis of primary osteoarthritis between August 2013 and July 2017. All patients had preoperative CT scans as part of their routine surgical planning. A total of 128 shoulders met our inclusion criteria. Glenoid version, inclination, and vault depth were measured by a fellowship-trained musculoskeletal radiologist. Glenoid wear pattern was also classified according to Walch et al. Glenoid version, inclination and vault depth were compared between males and females using the independent sample t-test. The association of Walch wear patternwith gender were evaluated using Fishersexact test. Statistical significance was set atp<0.05.Results: Male shoulders had significantly greater glenoid retroversion (17 degrees) than female patients (10 degrees). (p<0.001) Male shoulders also had significantly deeper glenoid vaults (2.1cm) than female shoulders (1.7cm) (p<0.0001). There was no difference in average glenoid inclination between male and female shoulders. (6.5 degrees inferior vs 8.6 degrees inferior) (p=0.20). Overall, Walch classification demonstrated a greater posterior wear pattern amongst males and greater central wear amongst females, which was statistically significant (P-value <0.0001).Discussion: This data reveals differences in glenoid wear between osteoarthritic males and female shoulders. Males demonstrate preferential posterior glenoid remodeling whereas females remodel centrally. The posterior wear pattern in males likely contributes to the relative increased posterior glenoid version as compared to females. The central wear pattern in females likely contributes to the relative smaller glenoid vault depth. https://doi.org/10.32873/unmc.dc.gmerj.1.1.082Dec. 2019  |  Vol. 1  |  Issue 1 1Rinehart et al: Gender Difference in Glenoid RemodelingPublished by DigitalCommons@UNMC, 2019
