Glenoid implant loose, good bone

General considerations

Displaced glenoid fractures may be associated with:

  • A previously loose glenoid implant
  • Loosening of a previously secure glenoid implant

The bone stock of the glenoid and neck of scapula is limited. Options for revision and fracture fixation may therefore be restricted.

per 10 D140 Definition

Etiology

A direct impact to the shoulder can cause a displaced fracture of the glenoid rim or neck of the scapula.

Clinical signs

  • Pain
  • Decreased range of motion
  • Weakness in the shoulder
  • Symptoms may not resolve with union of the fracture
  • Dislocation of the prosthesis may occur

Imaging

  • Standard trauma x-rays
  • A CT scan is recommended to evaluate the fracture and remaining glenoid bone stock in more detail and to plan reconstruction
  • 3D rendering may be helpful for assessment
