Elbow Replacement
Understanding the Elbow Joint
The elbow joint is a hinge joint formed by three bones:
- Humerus (Upper Arm Bone)
- Ulna (Forearm Bone)
- Radius (Forearm Bone)
The ends of these bones are covered with articular cartilage, a smooth, protective layer that allows seamless movement. The synovial membrane, a thin and smooth tissue, lines the inner surfaces of the joint, producing a small amount of fluid that reduces friction and enhances mobility. The joint is further stabilized by muscles, ligaments, and tendons, which provide strength and flexibility.
Elbow Joint Replacement (Arthroplasty)
Elbow replacement surgery is an effective solution for severe joint problems, particularly in cases of arthritis or irreparable fractures. The procedure replaces damaged parts of the humerus and ulna with artificial implants, restoring function and alleviating pain. Over 90% of patients experience significant relief and improved mobility post-surgery.
Indications for Elbow Replacement
Patients who may benefit from elbow replacement often suffer from:
- Rheumatoid Arthritis (RA)
- Advanced Osteoarthritis
- Unreconstructable Fractures
- Chronic Joint Instability
Preparing for Surgery
For a successful procedure and smooth recovery, preparation is key:
- Choose an experienced surgeon
- Understand the procedure thoroughly
- Keep medical records organized
- Complete pre-operative fitness tests (including BP and sugar level assessments)
- Discontinue blood-thinning medications if advised
- Discuss any concerns with your doctor
- Consult a Physical Therapist (PT) for pre-surgery exercises
Home Preparation
- Arrange daily-use items at an easily accessible height.
- Ensure assistance is available for daily tasks like dressing and cooking.
The Surgery
Most total elbow replacements are performed under general anesthesia. The procedure involves replacing the joint surfaces with specialized implants designed to restore movement and reduce pain.
Types of Implants
Linked/Coupled Implant:
- Provides stability by physically connecting the humeral and ulnar components.
- Newer implants allow better range of motion and longer durability.
-
Typically made of titanium/chrome cobalt alloy, secured with bone cement.
Example: Coonrad-Morrey Linked Semi-Constrained Elbow Arthroplasty - Ensures joint stability, even in cases of severe bone loss or ligament damage.
- Allows better restoration of elbow motion and function.
Post-Surgery Rehabilitation
Recovery after elbow replacement depends significantly on adherence to a structured physiotherapy program.
1-4 Weeks
- Gentle strengthening exercises for elbow, wrist, and shoulder muscles.
- Use of ice therapy (cryotherapy) to reduce swelling.
- Wearing a sling when outside for added protection.
- Passive and active range-of-motion exercises for elbow and wrist.
- Stretching exercises to maintain flexibility.
5-8 Weeks
- Continued active range-of-motion exercises (bending, straightening, and twisting the elbow).
- Strengthening and stretching exercises for the shoulder.
- Full recovery usually takes 1 to 3 months.
Life After Elbow Replacement
Patients who undergo total elbow replacement generally experience:
- Less pain
- Improved motion and strength
- Enhanced daily function
Successful recovery depends on a combination of surgical expertise and patient commitment to post-operative care. A well-structured rehabilitation program is crucial to achieving the best outcome and restoring full function to the elbow joint.
