Two Ais Cases, Two Surgeons, One Operating Room, One Day. The Results Of A Quality Improvement Initiative, Jonathan Warren, Robert C. Link, Sean Bonanni, John T. Anderson, Richard M. Schwend

Research Days

Background: To lessen surgical times for AIS patients undergoing posterior spinal instrumentation and fusion (PSIF), our department developed a quality improvement initiative where two AIS cases were completed in one day by a specialized team with two surgeons operating together in the same operating room (OR).

Objectives/Goal: We describe the results of this initiative and compare operative times and blood loss between cases to determine if operative time improves as experience with this structure increases.

Methods/Design: From 2017-2023, patients aged 10-18 years with AIS were prospectively scheduled to undergo primary PSIF on the dedicated “Two Spine Tuesday” at our institution. …

Common Misperceptions Of Child Abuse In Toddler Femur Fractures, Olivia Pruss, Jonathan Warren, Vincent Staggs, Grace Tideman, Collin Erickson, William L. Hennrikus, Richard M. Schwend

Research Days

Background: Current AAOS guidelines recommend that all children younger than thirty-six months with a femur fracture be evaluated for child abuse. However, the chance for abuse in walking-age children is highly unlikely at less than 20%.

Objectives/Goal: The purpose of this study is to identify how a patient’s age and femur fracture morphology impact the likelihood that providers assess a fracture as non-accidental and their decision to pursue further investigation of possible child abuse.

Methods/Design: This was a questionnaire study completed by clinicians from multiple specialties. There were 5 subgroup populations (6, 12, 18, 24, 35 months old) combined with …

Preoperative Srs-22 Scores Predict Postoperative Achievement Of Distribution-Based Mcid In Ais Patients Treated With Posterior Spinal Instrumentation And Fusion, Jonathan Warren, Cyrus Etebari, Morgan Whitmire, Kenneth Furlough, Brant Ansley, John T. Anderson, Richard M. Schwend

Research Days

Background: There is a growing body of literature assessing the role of preoperative patientreported outcome measures in predicting postoperative achievement of the minimal clinically important difference (MCID). To the best of our knowledge, there are no studies assessing whether preoperative SRS-22 scores are predictive of postoperative achievement of MCID in patient with adolescent idiopathic scoliosis (AIS).

Objectives/Goal: Our purpose is to determine if preoperative SRS-22 scores in patients with AIS who undergo posterior spinal instrumentation and fusion can predict postoperative achievement of MCID.

Methods/Design: SRS-22 forms were provided to all patients scheduled to undergo posterior spinal instrumentation and fusion. MCID …

Indications For Early Surgical Intervention In Adolescents With Salter-Harris Ii Distal Radius Fractures, Cyrus Etebari, Jonathan R. Warren, Olivia Pruss, Sricharan Yadali, Vincent Staggs, Micah K. Sinclair

Research Days

Introduction: Currently, there is little information regarding risk factors for failure of nonoperative treatment in Salter-Harris II distal radius fractures (SHII-DRF). Our purpose is to identify predictors of which patients will require acute surgery and which will develop late malunion based on degree of deformity and skeletal maturity.

Methods: This was a review of SHII-DRFs in patients 9 to 18 years of age, from 2017-2020. Demographics, initial displacement, displacement post-reduction, and displacement after cast removal were evaluated. Skeletal maturity was determined using Sander’s classification. These values were compared between patients who underwent casting alone, underwent acute surgery, or required late …

Predicting Avascular Necrosis After Unstable Slipped Capital Femoral Epiphysis, Jonathan Warren, Alexander Metoxen, Michael Held, Brant Ansley, Berglund Lisa

Research Days

Background: There is no consensus in the literature on the risk of developing avascular necrosis (AVN) after unstable slipped capital femoral epiphysis (SCFE). In recent years, a number of studies have sought to better characterize risk factors for AVN in this population. However, to the best of our knowledge, there is no study that uses predictive modeling to assess the chance of developing AVN based on different patient-centric factors.

Objectives/Goal: Our goal is to assess whether or not previously-published risk factors for AVN in unstable SCFE such as duration of symptoms, reduction type, type of surgery, timing of surgery, and …

Two Adolescent Idiopathic Scoliosis (Ais) Cases, Two Surgeons, One Operating Room, One Day. Faster And Safer Than One Case In A Day., Jonathan Warren, Robert C. Link, Sean Bonanni, John T. Anderson, Richard M. Schwend

Research Days

Background: To lessen surgical times for AIS patients undergoing posterior spinal instrumentation and fusion (PSIF), our department developed a quality improvement initiative where two AIS cases were completed in one day by a specialized team with two surgeons operating together in the same operating room (OR).

Objectives/Goal: Our purpose is to describe the results of this initiative and compare operative times and outcomes to single cases completed by a single surgeon during the same period.

Methods/Design: From 2017-2023, patients aged 10-18 years with AIS were scheduled to undergo primary PSIF on the dedicated “Two Spine Tuesday” at our institution (Group …
