What is Partial Shoulder Replacement or Partial Shoulder Arthroplasty (Hemiarthroplasty)?

Who is an ideal candidate for this treatment?

In most instances, patients are younger and more active, where only the ball (humeral ball) is damaged, and the socket (glenoid) cartilage is healthy. Fractures of the humeral head, avascular necrosis, or specific rotator cuff issues are the main reasons patients seek partial shoulder replacement.

Do I need help? Possible Signs

  • Grinding or “popping” sensations (crepitus), but better-preserved motion.
  • Difficulty lifting the arm overhead, and pain can interrupt sleep.
  • Pain usually is a result of a fracture or isolated joint damage, and has not responded to conservative treatments (ice, rest, NSAIDs, therapy, or injections).

If only part of your shoulder joint is damaged, we offer a targeted solution that can relieve pain while preserving more of your natural anatomy and get you back to what you love.

Non-Surgical options

  • Physical therapy – Strengthens the surrounding “helper” muscles.
  • Anti-inflammatory medications – Taken to manage daily inflammation.
  • Injections – Cortisone injections or hyaluronic acid are given to lower pain and increase the range of motion.
  • Activity modification – Swapping high-impact activities for low-impact ones.

Definition of Treatments:

The surgeon in a Partial Shoulder Replacement removes the damaged bone, and the Humeral head (ball) is replaced with medical-grade prosthetic components. The natural bone of your socket is untouched.

FAQs

Mobility

The partial shoulder replacement offers good mobility, but it depends on the socket condition, since the surgeon does not replace it. If the natural socket begins to wear down later, it can become painful and may require replacement.

Risk of Recurrence

Partial shoulder replacement may require future conversion to total replacement, requiring a second surgery (revision) if the natural socket develops arthritis later.

Cosmetic Consideration

The incision for total and partial shoulder replacement is the same for both procedures, featuring a single incision (typically 4–6 inches long) at the front of the shoulder. Modern suturing techniques, such as subcuticular stitches, minimize scar size and enhance its visibility over time.

Recovery Timeline

  • Recovering from a total shoulder replacement requires careful management during the 4-6 weeks to protect and heal the joint. During this time, it is important to wear a sling and limit yourself to passive movements only.
  • In the next 4 weeks, you can start active motion as the patient can remove the sling, allowing you to lift your own arm.
  • Rehabilitation and strengthening exercises using resistance bands and light weights typically continue for 2-4 months. The patient achieves full recovery and maximum strength usually within 4-6 months.

Considerations/Risks

Typical
  • Infection is always a standard risk for any joint replacement.
  • The patient can experience severe stiffness, or the “frozen shoulder” effect can occur if physical therapy is not regularly done.
  • Nerve Injury: Temporary numbness in the arm.
Atypical
  • Implant failure or fracture around the implant.
  • Chronic pain or limited improvement.
  • Progressive arthritis in the socket
  • Glenoid Erosion can occur when the new metal ball wears away your natural bone socket, eventually requiring a “total” future replacement.
