The Effect of Metal Instrumentation on Patient and Surgical Team Scatter Radiation Exposure Using Mini C-Arm in a Simulated Forearm Fracture Fixation Model.

Introduction: To our knowledge, no studies have studied the effect of metal instrumentation (MI) in the field of fluoroscopy regarding changes in the intensity, direction of scatter, and degree of radiation exposure to the patient and surgical team. The goal of this study was to determine whether the presence of MI increases scatter radiation exposure to the patient and surgical team when using a mini C-arm in the horizontal and vertical positions.

Methods: Four trials were conducted using a lamb limb specimen and a mini C-arm to simulate a forearm/wrist fracture fixation scenario.

Acute Perioperative Comparison of Patient-Specific Instrumentation versus Conventional Instrumentation Utilization during Bilateral Total Knee Arthroplasty.

Utilizing patient-specific instrumentation during total knee arthroplasty has gained popularity in recent years with theoretical advantages in blood loss, intraoperative time, length of stay, postoperative alignment, and functional outcome, amongst others. No study has compared acute perioperative measures between patient-specific instrumentation and conventional instrumentation in the bilateral total knee arthroplasty setting. We compared patient-specific instrumentation versus conventional instrumentation in the setting of bilateral total knee arthroplasty to determine any benefits in the immediate perioperative period including surgical time, blood loss, pain medication use, length of stay, and discharge disposition.

A Prospective, Randomized Trial Comparing Liposomal Bupivacaine vs Fascia Iliaca Compartment Block for Postoperative Pain Control in Total Hip Arthroplasty.

Background: Increasing demand for total hip arthroplasty (THA) in a climate of increasing focus on clinical outcomes, patient satisfaction, and cost has created a need for better acute postoperative pain control for patients. An ideal pain control method would have few side effects, decreased opioid consumption, improved pain control, early ambulation, and decreased hospital length of stay (LOS).

Methods: We performed a prospective randomized, controlled study involving 79 patients undergoing elective THA between June 2015 and February 2016.
