A hemiarthroplasty requires a repairable rotator cuff. A hemiarthroplasty is rarely if ever indicated in B3.1 fractures.

Supporting indications

  • Poor bone quality
  • Salvage procedure for failed reduction and fixation

Advantages

  • Provides a replacement for unreconstructable humeral head
  • If failure of fixation and/or avascular necrosis (AVN) are highly likely, primary arthroplasty may avoid a second surgery

Disadvantages

  • Resection of the humeral head
  • Possible failure of tuberosity repair
  • Possible pain and/or poor shoulder function
  • Possible arthroplasty failure
