Muscles that Move the Arm01:31

Muscles that Move the Arm

2.5K
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...

Area of Science:

  • Orthopedic Surgery
  • Arthroscopy
  • Shoulder Surgery

Background:

  • Arthroscopic rotator cuff repair requires sufficient visualization and space.
  • A narrow subacromial space complicates tendon release and repair, potentially leading to inaccurate suture placement.
  • Current distraction methods (manual or mechanical) have limitations like surgeon fatigue or brachial plexus overstretch.

Purpose of the Study:

  • To describe a novel technique using an arthroscopic laminar spreader for subacromial distraction.
  • To enhance visualization and working space during arthroscopic rotator cuff repair.
  • To evaluate the safety and efficacy of this distraction device.

Main Methods:

  • A specific laminar spreader is inserted into the subacromial space.
  • The device distracts the humeral head inferiorly from the acromion.
  • This technique facilitates rotator cuff release and repair, and can be used for various shoulder procedures.

Main Results:

  • The arthroscopic laminar spreader significantly improves subacromial space visualization.
  • It enables easier rotator cuff release and repair.
  • The device improves surgeon performance, reduces operative time, and enhances safety without surgical assistance.

Conclusions:

  • The arthroscopic laminar spreader is an effective tool for subacromial distraction in arthroscopic rotator cuff repair.
  • This technique offers improved visualization, easier surgical manipulation, and enhanced safety.
  • The device is versatile and applicable to various anterior and posterior shoulder repairs and reconstructions.
