The humerus can become severely damaged due to an acute injury or chronic disease, causing pain and discomfort. A shoulder hemiarthroplasty is a procedure to treat the shoulder joint, relieving pain and improving mobility. In partial shoulder replacement surgery, the damaged humeral head (the rounded end of the humerus) is replaced with a prosthetic (artificial) humeral head.

Anatomy and Physiology of Humerus

The humerus is the only bone in your upper arm between the elbow and shoulder. It is responsible for various arm movements, such as rotation at the shoulder joint, raising or lowering your arms, moving them behind or in front of your torso, and straightening or bending your elbow. The various parts of the humerus include:
  1. Proximal: The upper part of the humerus closest to the shoulder, which includes:
    1. A head (rounded part of the humerus)
    2. Tubercles (the bony area that serves as attachment points for the shoulder joint muscles)
    3. Surgical neck (the base of the proximal humerus)
  2. Body or Shaft: The long middle portion of the humerus 
  3. Distal: The lower part of the humerus closest to the elbow. It includes:-
    1. Epicondyles (bony protrusions that serve as attachment points for the lower arm, wrist, and hand muscles)
    2. Trochlea (interacts with the ulna bone in your lower arm)
    3. Capitulum (interacts with the radius bone of your lower arm)
    4. Fossae (a depression or hollow that accommodates the lower arm bones when the elbow joint is moved)
How is Shoulder Hemiarthroplasty Different from Shoulder Arthroplasty?
Shoulder arthroplasty is a total shoulder replacement surgery in which the humeral head and glenoid are replaced with a metal ball and plastic socket, respectively. Whereas shoulder hemiarthroplasty is a partial shoulder replacement surgery in which only the humeral head is replaced with a prosthesis, and the glenoid is left undisturbed. 

What is Prosthesis?
A prosthesis is an artificial implant to replace a missing or damaged body part. For a shoulder hemiarthroplasty, the prosthesis does not have a glenoid component. It consists of a stemmed metal humeral component and a customisable head neck and stem parts.

Conditions Treated with Shoulder Hemiarthroplasty

Conditions treated with Shoulder Hemiarthroplasty include: 
  1. Glenohumeral Arthritis: Also known as shoulder arthritis, it is a degenerative joint disease of the shoulder which includes damage to the articular surfaces of the humeral head or glenoid
  2. Primary Arthritis: Caused by the breakdown of cartilage that eases friction in the joint. You may need a shoulder hemiarthroplasty when there is:
    1. A deficiency in rotator cuff functions
    2. Inadequate glenoid bone stock
    3. High risk of glenoid loosening in active labourers and young patients
  3. Avascular Necrosis: Joint degeneration caused by decreased blood flow
  4. Capsulorrhaphy Arthropathy: A type of arthritis that is a long-term sequela, i.e., a complication caused by previous shoulder dislocation surgery 
  5. Rotator Cuff Tear Arthropathy: Occurs due to a rip in the rotator cuff’s tendon
  6. Chondrolysis: Destruction of the cartilage
  7. Proximal Humeral Fractures: One or multiple humeral head fractures due to an injury. These fractures include:
    1. Poor bone quality fractures
    2. Head-splitting fractures (a part of the head of the humerus dislocates and the other unfractured part remains attached to the shaft)
    3. Articular fractures (when a bone breaks inside or around a joint and causes significant destruction to the articular surface)
  8. Tumour: A tumour that causes damage to the humeral head, not harming other joint structures

Who needs Shoulder Hemiarthroplasty??

A shoulder hemiarthroplasty is generally done for the following candidates:
  1. Patients suffering from shoulder osteoarthritis
  2. Patients who have suffered a shoulder fracture
  3. Patients who have Glenohumeral Arthritis or Primary Arthritis
  4. Patients suffering from Capsulorrhaphy arthropathy or Rotator cuff tear arthropathy
However, shoulder hemiarthroplasty is not recommended for people with the following conditions:
  1. Neuropathic shoulder (decreased sensory stimulation due to nerve damage in the shoulder)
  2. Ankylosed shoulder (restriction or stiffness of joint due to abnormal bone fusion)
  3. Previous glenohumeral arthrodesis (an abnormal fusion of the glenoid and the head of the humerus)
  4. Fractures that can be treated with open reduction and internal fixation surgery
  5. Poor general health

How is Shoulder Hemiarthroplasty performed?

A shoulder hemiarthroplasty typically follows these steps:
  1. Step 1: Making an Incision and Accessing the Bone
    The surgeon will make a five to seven inches long incision at the front of your shoulder. They will gently move the nerves and blood vessels out of the way and cut some muscles and connective tissues to access your bone. 
  2. Step 2: Removing the Damaged Bone and Replacing it With a Prosthetic Head
    Your surgeon will remove the humerus’s damaged head and the surrounding degenerated cartilage on the humerus head. Next, the surgeon will fit the stem of the prosthesis in the long portion of your humerus. Sometimes, he/she may have to widen the inside opening of the humerus to fit the stem. 
  3. Step 3: Holding the Prosthesis in Place
    Once the surgeon puts the prosthesis in place, they will insert a particular type of cement to hold it in place. Furthermore, he/she will position the remaining structures of your joint to fit the prosthetic humeral head properly. 
  4. Step 4: Connecting the Muscles and Tissues and Closing the Wound
    The surgeon will repair the muscles and connective tissues and move the nerves and blood vessels to their normal position. Next, he/she will close your skin with sutures and apply a sterile bandage to the wound. 
Shoulder hemiarthroplasty can be of two types:
  1. Stemmed Hemiarthroplasty: The surgeon replaces the humeral head with a metal ball and stem similar to that used in total shoulder replacement. The procedure is recommended when the head of your humerus is severely fractured, but the socket is normal. It is also suggested when there is a large rotator cuff tear. 
  2. Resurfacing Hemiarthroplasty: The surgeon replaces the humeral head with a cap-like prosthesis and no stem. The procedure helps preserve bone and prevent the risk of component loosening. 
The selection of the procedure is based on your condition, causes of damage, and your doctor’s opinion. 

What Can You Expect Before the Surgery?

Consultation and Evaluation
