Changes In Sonographic Characteristics Of The UCL Following A 30-minute Swing Session In Female Collegiate Division I Golfers

Abstract

PURPOSE: Medial elbow complex injuries have been reported in competitive and recreational golfers. Ultrasound imaging (USI) is a common method for assessing characteristics of the UCL. Prior research has found that sonographic characteristics of the UCL and MJS may be altered due to loads applied to these structures. Loads resulting from repeated golf swings can potentially alter these sonographic characteristics. The purpose of this pilot study was to examine the difference of sonographic characteristics of the UCL and MJS before and after a 30-minute golf swing session by asymptomatic female collegiate golfers. METHODS: Seven asymptomatic NCAA Division I collegiate female golfers (age 19.6 ± 1.5 yrs) participated. Ultrasound images of the UCL and medial joint space of both elbows were obtained using a GE LOGIQ E ultrasound unit. Participants were placed supine with elbow position at 30 degrees, with a wedge placed underneath the humerus creating a gravity induced valgus force on the MJS. Measurements of the thickness of the UCL at mid substance and trochlea apex and MJS were performed, and the difference of pre and post session sonographic measurements were assessed by paired t-tests. RESULTS: There were no statistically significant differences in sonographic UCL and MJS measurements pre and post golf swing session (t = .55-2.3, p > .05). CONCLUSIONS: This pilot investigation found no differences in sonographic UCL and MJS measurements following a single 30-minute swing session. Further research is needed to examine potential differences using larger sample sizes, longer sessions, sessions over time, and more heterogeneous study populations.
