Muscles that Move the Arm01:31

Muscles that Move the Arm

5.4K
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
This summary is machine-generated.

Infraglenoid tubercle avulsion fractures are rare. Nonoperative treatment of a displaced fracture resulted in malunion and early osteoarthritis, but good function without instability.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Radiology

Background:

  • Infraglenoid tubercle avulsion fractures are exceptionally uncommon shoulder injuries.
  • These fractures often involve the inferior aspect of the glenoid cavity.

Observation:

  • A 38-year-old male sustained a left shoulder glenoid cavity fracture with infraglenoid tubercle avulsion after a fall.
  • The patient opted for nonoperative management due to refusal of surgical intervention.

Findings:

  • Radiographic and CT follow-up at 18 months demonstrated a malunited infraglenoid tubercle.
  • Early signs of glenohumeral osteoarthritis were evident on imaging.
  • Despite malunion, the patient experienced no shoulder instability or pain, reporting a fair-good functional outcome.

Implications:

  • This case highlights the potential for nonoperative treatment of displaced infraglenoid tubercle avulsion fractures.
  • CT evaluation is crucial for assessing the anatomic outcome of such injuries.
  • Further research is needed on the long-term consequences of nonoperatively managed displaced infraglenoid tubercle avulsion fractures.
