Research Interests
Surgical Interface Design Lab
The mission of the Surgical Interface Design Lab is to create and study tools that improve the ability of surgeons to perform progressively more complex procedures through more minimally invasive approaches. The lab does this by combining navigation, visualization and robotics technologies and refining the design to provide an intuitive, natural interface for the surgeon and the patient.
Clinical Studies Lab
The Clinical Studies Lab encompasses a variety of research initiatives involving retrospective analysis and cohort studies. Our goal is to examine correlations between data metrics of traumatic spinal cord injury, spinal metastasis, cranial decompression, traumatic brain injury, and endoscopic spine surgery versus neurological outcomes, morbidity/mortality and complication rates.
Current Projects
Traumatic Brain Injury (Megan Nedden)
We are working on a retrospective chart review for patients with a traumatic brain injury (TBI) requiring a decompressive craniectomy. Specifically, we are looking to see if having a decompressive craniectomy within 24 hours of the TBI improves a patient’s neurological outcomes. This is part of the Shapiro Summer Research program at UWSMPH.
Past Projects
Cranial Decompression (Robert Sterner)
Currently, we are examining the association of time to cranial decompression following head trauma on neurological outcomes.
Complications Associated with Endoscopic Spine Surgery (Delaney Kramar)
We are investigating complications associated with endoscopic spine surgery. It is a retrospective chart review that will provide observational data on the complications found in a group of patients over 18 who underwent this type of procedure. With this project we intend to add more information to the limited existing studies on complications associated with endoscopic spine surgery.
Spinal Oncology (James Liu)
Spinal metastasis accounts for 5% to 10% of cancer patients. While surgical treatment for metastatic epidural spinal cord compression has traditionally been palliative with a life expectancy of 3 months, improved treatment and early detection has resulted in life expectancy increases. This raises questions of which factors may increase risk for spinal tumors and the long-term outcome of patients who have undergone metastatic spinal surgery. Here we conduct a retrospective analysis of 230 spinal tumor patients who have undergone surgery with a special focus on 43 metastatic patients. Our goal is to examine the relationship between demographics, comorbidities, surgical metrics, tumor pathology vs. spinal metastasis occurrence, morbidity, mortality, and neurological outcome.
Traumatic Spinal Cord Injury (Robert Sterner)
Traumatic spinal cord injury (tSCI) is a devastating event that can result in permanent disability or loss of function. To date, the optimal timing of surgical decompression in tSCI patients remains controversial. Our project aims to examine the neurological outcomes of tSCI patients undergoing: (1) early versus late surgical decompression (<12 hours) versus (>12 hours) and (2) transport in (<6 hours) versus (>6 hours). This study suggested an association of decompression within 12 hours and short transport times (<6 hours) with significant improvements in neurological outcomes. These results were published in Spine.
Prophylactic anticoagulation in head trauma patients (Daniel L. Traverzo)
We worked on a study which reviewed the association of prophylactic anticoagulation in head trauma patients at UW Hospital and how it affected hematoma progression. Prophylactic anticoagulation is thought to be a potential cause of worsening intracranial hemorrhage in patients administered prophylactic doses of anticoagulation after trauma. It is not well studied how the timing of administration of prophylactic anticoagulation affects intracranial hemorrhage in head trauma patients, which was the basis of the study. This was part of the Shapiro Summer Research program at UWSMPH.
Low-Cost Endoscopic Spine Simulator (James Liu + Paul Page)
Minimally invasive endoscopic techniques in spine surgery continue to gain in popularity. Unfortunately, there is a long learning period for novice endoscope users to acquire basic skills, and complex training simulators are frequently cost-prohibitive. A low-cost endoscopic spine training model was created utilizing a budget of less than 65 USD and tested on a cohort of surgical trainees following a training curriculum consisting of five tasks designed to mimic standard techniques frequently utilized in endoscopic spine surgery. Our study demonstrated the feasibility of a low-cost endoscopic spine trainer as well as its efficacy in improving basic endoscopic skills in trainees. These results were published in Cureus.
