⬛ There are two aspects that are relevant to scapulothoracic kinematics: periscapular stabilization and scapular motion.
⬛ One has to understand that scapular motion involves inherently clavicular motion, both at the sternoclavicular and at the acromioclavicular joints; both bones move synchronously.
⬛ Here, the clavicle moves as a strut connecting the sternum which will be our point of reference regarding the axial body and the scapula, and ultimately helping scapular motion.
𝗥𝗲𝘀𝘁𝗶𝗻𝗴 𝗢𝗿𝗶𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝘁𝗵𝗲 𝗦𝗰𝗮𝗽𝘂𝗹𝗮 📍
⬛ The scapula has a normal resting orientation of 30 degrees of anteversion, 3–10 degrees of abduction and 10–20 degrees of anterior tilt.
⬛ Usually it reaches up to 60 degrees of abduction, 20 degrees of posterior tilt and 10 degrees of external rotation initially 6 degrees of internal rotation during the first half of elevation, to later add 16 degrees of external rotation.
𝗦𝗰𝗮𝗽𝘂𝗹𝗮𝗿 𝗠𝗼𝘁𝗶𝗼𝗻 𝗠𝗲𝗰𝗵𝗮𝗻𝗶𝗰𝘀 🔄
⬛ Scapular motion is a combination of rotational movements along three axes anteroposterior, superoinferior, and lateromedial with gliding movements around the posterolateral rib cage through the scapulothoracic interface.
⬛ These movements can be described as follows.
𝗣𝗿𝗼𝘁𝗿𝗮𝗰𝘁𝗶𝗼𝗻 ➡️
⬛ Combination of lateral gliding winging away from the spine, anterotation at the acromioclavicular joint and anterior motion of the lateral clavicle.
𝗥𝗲𝘁𝗿𝗮𝗰𝘁𝗶𝗼𝗻 ⬅️
⬛ Combination of medial gliding toward the spine, retrorotation at the acromioclavicular joint and posterior motion of the lateral clavicle.
𝗨𝗽𝘄𝗮𝗿𝗱 𝗥𝗼𝘁𝗮𝘁𝗶𝗼𝗻 ⬆️
⬛ Combination of coronal-plane rotation resulting in the glenoid facing upwards, superior displacement of the lateral clavicle and slight lateral scapular gliding.
𝗗𝗼𝘄𝗻𝘄𝗮𝗿𝗱 𝗥𝗼𝘁𝗮𝘁𝗶𝗼𝗻 ⬇️
⬛ Combination of coronal-plane rotation resulting in the glenoid facing downwards, inferior displacement of the lateral clavicle and slight medial scapular gliding.
𝗘𝗹𝗲𝘃𝗮𝘁𝗶𝗼𝗻 ⬆️
⬛ Upward scapular gliding and superior lateral clavicular displacement.
𝗗𝗲𝗽𝗿𝗲𝘀𝘀𝗶𝗼𝗻 ⬇️
⬛ Downward scapular gliding and inferior lateral clavicular displacement.
𝗗𝘂𝗿𝗶𝗻𝗴 𝗔𝗿𝗺 𝗘𝗹𝗲𝘃𝗮𝘁𝗶𝗼𝗻 💪
⬛ In elevation of the arm, scapular abduction has three effects: increase of humeral motion relative to the thorax, orients muscles for optimal function and positioning the glenoid under the humerus for load sharing.
𝗦𝘁𝗲𝗿𝗻𝗼𝗰𝗹𝗮𝘃𝗶𝗰𝘂𝗹𝗮𝗿 𝗝𝗼𝗶𝗻𝘁 🔗
⬛ The sternoclavicular joint works as a ball-and-socket joint.
⬛ Its ranges go from 45 degrees of elevation to 15 degrees on depression, ± 30 degrees on protraction retraction, and 30–45 degrees on axial rotation.
⬛ This motion allows the clavicular strut to move in coordination with the scapula.
