Total Ankle Arthroplasty Templating: Preoperative Computer Templating Correlates Highly with Intraoperative Component Selection.

Proper alignment and sizing are critical to the performance of a successful total ankle arthroplasty. While it is common practice in preoperative planning prior to total knee and total hip arthroplasty, preoperative computer templating has not been well established in the setting of total ankle arthroplasty. A retrospective review of all total ankle arthroplasties performed during a 10-year period by a single fellowship-trained orthopaedic surgeon was conducted. Computer templating was utilized for all preoperative Anterior to Posterior (AP) and lateral standing radiographs, and templated component sizes were compared to the operative reports and postoperative radiographs to determine the precision of the available templates. Statistical analysis was performed with Interclass Correlation Coefficients (ICC) and descriptive statistical tests. Seventy patients with a mean age of 64.8 years (range, 48-87) and mean BMI of 30.34 (range, 19.1-55.6) were included. The ICC demonstrated that both the AP (ICC 0.80 - 95% CI 0.679-0.876) and lateral (ICC 0.786 - 95% CI 0.655-0.867) radiographs provided accurate tibial total ankle arthroplasty component templating. Similarly, the AP (ICC 0.842 - 95% CI 0.745-0.902) and lateral (ICC 0.809 - 95% CI 0.692-0.881) radiographs provided accurate talar templating. No differences were observed when comparing AP to lateral radiographs in percentage of correct component templating: tibial AP 61.4% vs lateral 58.6%, p = .119 and talar component AP 57.1% vs lateral 45.7%, p = .176. These study findings demonstrate that preoperative templating for total ankle arthroplasties is accurate in determining appropriate implant sizing. Accurate templating is an absolute necessity for future templating studies.

Resource Use After Unwanted Sexual Experiences in Undergraduates: A Comprehensive Evaluation of Factors Related to the Decision to Seek Help.

The risk for sexual victimization in college is high, and although there can be significant mental and physical consequences for the survivor, resource utilization for this issue is extremely low. The current study used the frameworks of both the ecological model and the theory of planned behavior to examine factors related to resource use in undergraduate survivors of unwanted sexual experiences. The sample consisted of 217 undergraduates who reported at least one unwanted sexual experience while in college (89% female, 76.5% Caucasian, M age 19.6). Data were collected in an online survey from a private liberal arts college, and were analyzed using decision tree modeling. Results suggested that resource use was less related to demographic or event characteristics, but rather related to victim response to the event as well as perceptions about control over potential resource use. In addition to key assault prevention efforts, it is thus important to also support survivor mental health and self-efficacy postassault.

Coronal Remodeling Potential of Pediatric Distal Radius Fractures.

BACKGROUND: Distal radius fractures in the pediatric population are common injuries with a remarkable capability to remodel. The degree of angulation that can reasonably be expected to remodel is controversial though, particularly when it comes to angulation in the coronal plane. The purpose of this study was to quantify the rate of coronal remodeling, via the distal radius physis, present in a retrospective cohort of skeletally immature patients with coronally angulated distal radius fractures. METHODS: A retrospective chart review was performed to identify skeletally immature patients treated for an angulated distal radius fracture with over 10 degrees of angulation in the coronal plane during the healing process at a single institution by either a pediatric orthopaedic surgeon or an orthopaedic trauma surgeon from 2009 to 2018. Coronal angulation was measured at every visit where radiographs were available from time of injury to the final follow-up visit to determine the rate of remodeling. RESULTS: In total, 36 patients with distal radius fractures with a mean age of 7.93 years (range, 4 to 12 y) at the time of injury were identified. The median peak angulation during the healing process in the coronal plane was 17 degrees (range, 12.4 to 30.4 degrees). The mean follow-up period was 6.4 months from the time of maximum angulation to the final visit. The median time from cast removal to final follow-up was 6.59 months (range, 2.5 to 8.72 mo). At final follow-up, the median coronal angulation was 3.35 degrees (range, 0.24 to 14.0 degrees). At the 95% confidence level, remodeling rates ranged from 2.00 to 2.59 degrees per month. The mean rate of coronal angulation remodeling from maximum angulation to final follow-up was 2.30 degrees per month. CONCLUSIONS: Distal radius fractures have a large capacity to remodel in the pediatric population. This remodeling occurs in a predictable and reliable manner, even in the coronal plane. On the basis of this study, coronal angulation was shown to remodel at a rate of at least 2 degrees per month for the first 6 months following the injury, which should likely continue at a similar rate for the first year after the injury. Repeat manipulation is not indicated in skeletally immature patients where the maximum coronal angulation is <24 degrees, which provides a conservative estimate of the amount of remodeling that can be expected to occur in the first year after fracture. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

Implementation and Evaluation of Shared Medical Appointments for Type 2 Diabetes at a Free, Student-Run Clinic in Alamance County, North Carolina.

INTRODUCTION: Type 2 diabetes is a significant problem among uninsured patients. Shared medical appointments (SMA) have been shown to improve outcomes in type 2 diabetes. We hypothesized that the SMA model could be adapted for a non-profit clinic in North Carolina that serves uninsured patients with diabetes that have incomes at/below 150% of the federal poverty line. RESEARCH DESIGN AND METHODS: We implemented and sustained a patient-driven, student-led SMA model that incorporated the monthly rotations of students, physician assistant, and undergraduate students as well as pharmacy residents and an endocrinologist who collectively provide diabetes care at the free clinic. SMA groups are 'open' cohorts and include 4-12 patients scheduled for the monthly clinic. Teams of transdisciplinary trainees work together to perform triage, medication reconciliation, brief history, and physical exam, after which patients participate in the SMA. The endocrinologist evaluates SMA patients individually during and after the visit. RESULTS: Between November 2015 and January 2017, we enrolled 29 patients in SMA. There was high variability in HbA1c at baseline. Among eight type 2 diabetes patients seen in endocrine clinic and with complete data one year before and after SMA implementation, the mean (SD) HbA1c before SMA was 9.7% ± 1.7% (83±7 mmol/ mol); mean HbA1c after SMA was 9.2% ± 1.8% (77 ± 8mmol/mol). The median HbA1c before SMA was 9.5% (80 mmol/mol); median HbA1c after SMA was 8.9% (74 mmol/mol). Overall, 6/8 patients showed decreased HbA1c after SMA although there was variability between individuals in response of glycemic control to SMA. SMA increased clinic efficiency and offered an opportunity to integrate transdisciplinary trainees. Trainees gain experience with novel models of care and the complexities of the patient experience of diabetes. CONCLUSIONS: We hope this observation encourages others to implement such programs to enhance the evidence-base for SMA to address health disparities and increase the quality of free diabetes care.
