Background: Few specific risk factors are known for shoulder injury in professional pitchers. New pitch-tracking data allow for risk stratification based on advanced metrics.

Purpose/Hypothesis: The purpose of this study was to determine the association between shoulder injury, pitch frequency, and pitch metrics (velocity, total break, break angle, and spin rate) for the 4-seam fastball, curveball, and slider. We hypothesized that more frequent use of the 4-seam fastball would be associated with shoulder injury.

Study Design: Case-control study; Level of evidence, 3.

Methods: The Major League Baseball (MLB) database was queried for pitchers who had been placed on the injury …

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to capture patient-reported outcomes (PROs) in an efficient manner. Few studies have assessed this instrument postoperatively.

Purpose: To compare the PROMIS Physical Function computer adaptive test (PROMIS PF CAT) and Upper Extremity (PROMIS UE) item bank to other previously validated PRO instruments and to evaluate ceiling and floor effects and construct validity responsiveness in patients who underwent operative interventions for shoulder instability.

Study Design: Cohort study (diagnosis); Level of evidence, 2.

Methods: A total of 72 patients who underwent operative interventions for shoulder instability completed the American Shoulder and Elbow …

Characteristics Of Clinical Shoulder Research Over The Last Decade: A Review Of Shoulder Articles In The Journal Of Bone & Joint Surgery From 2004 To 2014, Gary M. Gartsman, Brent J. Morris, R. Zackary Unger, Mitzi S. Laughlin, Hussein A. Elkousy, T. Bradley Edwards

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: The purpose of this study was to determine characteristics and trends in published shoulder research over the last decade in a leading orthopaedic journal.

Methods: We examined all clinical shoulder articles published in The Journal of Bone & Joint Surgery from 2004 to 2014. The number of citations, authorship, academic degrees of the authors, country and institution of origin, topic, level of evidence, positive or nonpositive outcome, and inclusion of validated patient-reported outcome measures were assessed for each article.

Results: Shoulder articles that included an author with an advanced research degree (MD [Doctor of Medicine] with a PhD …
