Differences of the distance* and anglefrom the line of inter-spinous process of the upper thoracic vertebra at each interval of motion degree of glenohumeral and scapulohumeral rhythm on operated and contralateral shoulder at 30°, 60°, 90°, 120° of abduction
Interval Distance* (mm) Angle(°)
RTSA Normal RTSA Normal
0°- 30° −12.1 9.1 0.8 2.0
30°- 60° 18.3 13.9 13.8 6.5
60°- 90° 18.7 7.4 6.3 5.8
90°- 120° 28.4 19.3 12.6 8.0

RTSA = reverse total shoulder arthroplasty; Distance* = The distance between line of inter-spinous process of the upper thoracic vertebra and inferior pole of scapula; Angle = The angle between line of inter-spinous process of upper thoracic vertebra and scapular medial border.
