Physical Examination Versus Ultrasonography For Detection Of Ulnar Nerve Subluxation In Professional Baseball Pitchers, Austin Looney, Hannah Day, Manoj Reddy, Ryan Paul, Levon Nazarian, Steven Cohen

Rothman Institute Faculty Papers

Background: Despite the importance of accurately detecting ulnar nerve subluxation in vulnerable athletes, few studies have compared the performance of physical examination and ultrasound in this population. Purpose/Hypothesis: The purpose of this study was to compare the diagnostic validity of physical examination versus ultrasound in detecting ulnar nerve subluxation at the cubital tunnel of the elbow in professional baseball pitchers. It was hypothesized that ultrasound would more sensitively detect ulnar nerve subluxation. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Physical and sonographic examinations for ulnar nerve subluxation were performed on 186 elbows of 95 consecutive male professional …

Impact Of Draft Order On Stress Sonography Of The Ulnar Collateral Ligament Of The Elbow In Professional Baseball Pitchers: An 18-Year Study, Adeeb Hanna, John Sonnier, Brian Fliegel, Matthew Sherman, Michael Ciccotti, Robert Jack, Steven Cohen

Rowan-Virtua Research Day

Background: The MLB draft is a common route for players to enter professional baseball in the United States. Individuals taken in earlier rounds are typically higher-performing players. When looking at pitchers specifically, higher performance at the amateur level may be associated with increased frequency of adaptive change in the throwing elbow.

Purpose/Hypothesis: To determine if players taken in earlier rounds of the MLB draft have a greater frequency or extent of pathological change in the elbow, as measured by dynamic stress ultrasound.

Study Design: Retrospective Cohort Study Methods: Dynamic stress ultrasounds (SUS) were performed over an 18-year period on the …

Adaptive Changes Of The Ulnar Collateral Ligament Of Professional Baseball From Different Climates Over Multiple Seasons: An 18-Year Study, Adeeb Hanna, Brian Fliegel, John Sonnier, Matthew Sherman, Michael Ciccotti, Robert Jack, Steven Cohen

Rowan-Virtua Research Day

Background: The ulnar collateral ligament (UCL) is put under high levels of stress through the overhead throwing motion typical of professional baseball pitchers. In response to repetitive stress the UCL undergoes adaptive changes including thickening of the ligament and increased joint laxity under valgus stress. Studies examining the adaptive changes in the elbows of professional pitchers over multiple seasons are limited. Investigations such as this one offer insight into the changes in the UCL of professional pitchers over multiple years of professional play as well as the risk for injuries that may be associated with these changes.

Purpose/Hypothesis: The purpose …

Does Prehabilitation Before Surgery Affect Return To Sport In Baseball Pitchers With Partial Ulnar Collateral Ligament Tears?, Kourtney Snigar, Ryan W. Paul, Joshua M. Spada, Usman Zareef, Anya Hall, Brandon J. Erickson, Michael G. Ciccotti, Stephen J. Thomas

Rothman Institute Faculty Papers

BACKGROUND: Purposeful rehabilitation before surgery (prehabilitation) has been researched and implemented in the treatment of anterior cruciate ligament tears. However, it is unclear whether prehabilitation would affect outcomes for baseball pitchers with partial ulnar collateral ligament (UCL) tears.

PURPOSE/HYPOTHESIS: The purpose of this study was to determine whether baseball pitchers with partial UCL tears who completed ≥4 weeks of prehabilitation (prehab group) have different return to play (RTP) outcomes than pitchers with 0 to 3 weeks of preoperative physical therapy (no prehab group). We hypothesized that pitchers in the prehab group would have similar RTP rates compared with pitchers in …
