Methods and Materials
The participants of this study were 14 male baseball players who participated 4 or more years in baseball activities (11.6 ± 0.6 year; playing experience,
4.5 ± 0.8 years).
We also recruited 16 untrained healthy control subjects (11.8 ± 0.7 years).
Ultrasonography of the shoulder and elbow regions was performed using a GE Logiq 7 ultrasound device with a 7–12 MHz linear probe.
The thickness of the subscapular and supraspinatus tendon and the articular cartilage thickness of the humeral head were assessed at the shoulder region.
The thickness of the ulnar collateral ligament (ULC) was measured (Fig.
1).
With the elbow extended,
a valgus force was applied (Fig.
2).
The medial ulnohumeral distance was measured with no force and then with a valgus force applied to the elbow.
The articular thickness of the humeral capitulum was also measured.
