Muscle Coordination and Action01:24

Muscle Coordination and Action

Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement.
Muscles that Move the Arm01:31

Muscles that Move the Arm

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Summary

Adding biceps tenodesis to rotator cuff repair (RCR) does not negatively impact patient outcomes at two years. This holds true even for patients with larger rotator cuff tears undergoing the combined procedure.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Shoulder Reconstruction

Background:

  • Rotator cuff tears are common, often requiring surgical intervention.
  • Biceps tenodesis is sometimes performed concurrently with rotator cuff repair (RCR).
  • The impact of concomitant biceps tenodesis on RCR outcomes requires further investigation.

Purpose of the Study:

  • To compare functional outcomes and patient satisfaction after RCR with biceps tenodesis versus isolated RCR.
  • To evaluate the influence of tear size on outcomes in patients undergoing both procedures.

Main Methods:

  • Retrospective case study comparing two groups: RCR with biceps tenodesis and isolated RCR.
  • Exclusion criteria included prior shoulder surgery, irreparable tears, and advanced arthritis.
  • Primary outcomes included validated shoulder scores (ASES, SST) and patient-reported satisfaction at 2-year follow-up.

Main Results:

  • No significant differences in pain, ASES scores, or SST scores were observed between the groups at 2 years.
  • Patients undergoing RCR with biceps tenodesis had significantly larger rotator cuff tears.
  • Despite larger tears, the combined procedure group reported comparable outcomes.

Conclusions:

  • Concomitant biceps tenodesis is a safe adjunct to RCR, not compromising functional outcomes.
  • The procedure offers comparable results to isolated RCR, even in cases with larger tears.
  • This suggests biceps tenodesis can be reliably performed without negatively affecting shoulder function post-RCR.
