Significant pedunculated submucosal leiomyoma resembling uterine prolapse

The current surgical training environment has sparked a paradigm shift toward the use of surgical training simulation. An apprentice-based model has historically been used in surgical education, but current financial and practical constraints have led to a more variable training experience. Surgical simulation has demonstrated efficacy in many facets of orthopaedic training and has most recently been implemented to fine-tune surgical skill in reconstruction of traumatic skeletal injuries. Although some surgical skills learned during residency training are not fully used in later practice, most surgeons require a baseline level of competence in managing skeletal trauma. Fracture surgery is heavily dependent on technical skill. Trainee simulation use in skill acquisition has potential to improve proficiency during actual surgery. Furthermore, in a specialty where the standard axiom has been repetition matters, education augmentation with simulation provides overall benefit. Work remains to maximize the effectiveness of surgical simulation in fracture treatment through improved model integration and access.
Managing costs and improving access to care are two important goals of healthcare policy. The purposes of this study were to (1) evaluate the changes in distribution of total shoulder arthroplasty (TSA) cases in the state of Texas from 2010 to 2015 and (2) to evaluate patient access to TSA surgery centers as measured by driving miles.
Inpatient (IP) and outpatient (OP) records were obtained from 2010 to 2015 from the Texas Department of State Health Services. All primary elective anatomic or reverse TSAs for patients with Texas-based home residence zip codes were included. Driving miles between patient zip codes and their chosen TSA surgery centers were estimated, and the results were compared between IP (high-volume [HV-IP] or low-volume [LV-IP]) and OP centers. Paired student t-tests, multivariate regressions, and mixed-model analysis of variance (ANOVA) were performed for volume comparisons, interactions between TSA centers types, and yearly trend data, respectively.
Between 2010 and 2015, a total of 21,092 TSA procedures were performed across 321 surgery centers in the state of Texas (19,629 IP [93.1%] and 1,463 OP [6.9%]). During this time, the cumulative volume of IP TSA per 100,000 Texas residents increased by 109.1%, whereas the cumulative volume of OP TSA increased by 143.7%. Approximately 85.5% of included patients resided within 50 miles of any TSA surgery center; however, only 47.0% of the total Texas population resided within 50 miles of any TSA surgery center. This relationship remained true at every time point irrespective of their volume designations (OP, IP, HV-IP, and LV-IP).
Despite the overall increase in TSA volume over time, the majority all TSA utilization in the state of Texas occurred in patients who resided within 50 miles of a TSA center. Increasing volume seems to reflect concentration of care into HV-IP and OP centers. Strategies to improve access to TSA care for underserved areas should be considered.

A paucity of data exists on safe platelet and international normalized ratio (INR) thresholds for hip fracture surgery. Recent work has called into question the safety of preoperative INRs < 1.5 for total knee arthroplasty, and optimal platelet thresholds are unknown. The purpose of this study was to identify the risk of 30-day postoperative morbidity and mortality in patients with thrombocytopenia or elevated INRs undergoing hip fracture surgery.
The National Surgical Quality Improvement Program database was queried for patients undergoing surgical treatment of a native hip fracture from 2012 to 2017 (N = 86,850). Patient demographic, laboratory, and complication data were collected. Patients with preoperative platelet counts or INRs within one day of surgery were included for analysis. Preoperative platelet counts and INRs were divided into four groups (<50 k/μL, ≥50 k to 100 k/μL, ≥100 k to 150 k/μL, ≥150 k/μL, and ≤1.0, >1.0 to 1.5, >1.5 to 2.0, and >2.0, respectively). Multivariable lolargest effect sizes observed starting at INRs >1.5.
The results of this study suggest that preoperative platelet thresholds of <100,000/μL and INR thresholds of 1.5 serve as an important risk factor for complications after hip fracture surgery. Future work is warranted to determine whether preoperative platelet transfusions and/or INR reversal will improve outcomes for these patients.
Prognostic Level III.
Prognostic Level III.With an increasing number of total hip and knee arthroplasties being done at surgical centers and vascular surgeons often not immediately available in this setting, it is critical for orthopaedic surgeons to be comfortable with the acute surgical management of vascular injuries. Although they are fortunately uncommon in primary total hip and knee arthroplasties, damage to a major artery or vein can have potentially devastating consequences. Surgeons operating both in a hospital and an ambulatory surgical setting should be familiar with techniques to gain proximal control of massive bleeding because the principles can be helpful in primary and revision arthroplasties. In this study, we review the vascular anatomy around the hip and knee and the surgical management of these potentially catastrophic complications.
The Zimmer Modular Revision hip (ZMR) system is available in two stem options, a porous-coated cylindrical (PCM) and a taper (TM) stem. Several concerns have been reported regarding modular implants. Specifically, because of early junctional fractures, the ZMR system was redesigned with a wider modular interface. Methylene Blue As such, we designed a study assessing long-term ZMR survivorship and functional and radiographic outcomes.
A search of our institutional research database was performed. A minimum 10-year follow-up was selected. The following two cohorts were created PCM and TM stems. The Kaplan-Meier survival analysis was performed, and causes of stem failure requiring revision surgery were collected. Functional outcomes as per the Harris Hip Score and radiographic stem stability were assessed as per the Engh classification.
A total of 146 patients meeting the inclusion criteria were available for follow-up (PCM = 68, TM = 78). The mean follow-up was 13.4 years clinically and 11.1 years radiographically for the PCM cohort.
