A hemiarthroplasty requires a repairable rotator cuff.

Supporting indications

  • Poor bone quality
  • Humeral head ischemia in the elderly patient
  • Intraoperative failure of osteosynthesis

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
  • Risk of damage to the axillary nerve depending on the approach chosen
