Muscles of the Shoulder01:23

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

    Summary

    Coracoacromial Ligament (CAL) release after Reverse Shoulder Arthroplasty (RSA) significantly improves shoulder range of motion (ROM), especially internal rotation. This procedure may help overcome ROM limitations following RSA surgery.

    Area of Science:

    • Orthopedic Surgery
    • Biomechanical Research
    • Cadaveric Studies

    Background:

    • Reverse Shoulder Arthroplasty (RSA) is a common procedure for complex shoulder conditions.
    • Postoperative range of motion (ROM), particularly internal rotation (IR), can be limited after RSA.
    • The Coracoacromial Ligament (CAL) is a potential factor contributing to ROM deficits.

    Purpose of the Study:

    • To evaluate the impact of Coracoacromial Ligament (CAL) release on shoulder range of motion (ROM) after Reverse Shoulder Arthroplasty (RSA).
    • To specifically assess the effect on internal rotation (IR) to the back.

    Main Methods:

    • Ten fresh-frozen cadaveric shoulders underwent RSA followed by CAL release.
    • Shoulder ROM was measured using a goniometer before and after CAL release.
    • Internal rotation to the back was quantified by measuring thumb elevation distance.

    Main Results:

    • CAL release significantly improved overall shoulder ROM in all measured planes.
    • Internal rotation to the back improved by an average of 4 cm.
    • Significant gains were observed in internal rotation in abduction (7°), external rotation in abduction (8°), external rotation at the side (9°), forward elevation (10°), abduction (6°), and extension (11°).

    Conclusions:

    • CAL release following RSA demonstrates a significant positive effect on shoulder ROM, including IR to the back.
    • This technique presents a potential solution for improving ROM deficits, especially internal rotation, after RSA.
    • Further clinical studies are warranted to validate the clinical applicability of CAL release post-RSA.
