What is Shoulder Joint Replacement?

Total shoulder replacement surgery is performed to relieve symptoms of severe shoulder pain and disability due to arthritis. In this surgery, the damaged articulating parts of the shoulder joint are removed and replaced with artificial prostheses. Replacement of both the humeral head and the socket is called a total shoulder replacement.

What are the Indications for Shoulder Joint Replacement?

Total shoulder joint replacement is a surgery indicated for conditions such as osteoarthritis or rheumatoid arthritis when medication, injections, physical therapy, and activity changes do not help relieve pain. Your doctor recommends surgery when you have the following symptoms: Severe shoulder pain that restricts daily activities. Moderate to severe pain during rest. Weakness and/or loss of motion.

What is the MultiLoc™ Humeral Nailing System?

The MultiLoc™ Humeral Nailing System is an advanced implant designed to treat fractures of the proximal humerus and humeral shaft. It features both short and long nail options to accommodate different bone anatomies. Its straight-nail design, multiplanar locking screws, and screw-in-screw technology offer exceptional stability and fixation in complex shoulder fractures.

When is the MultiLoc™ Humeral Nailing System Recommended?

This system is recommended in several situations, including:

Displaced two-, three-, or four-part fractures of the proximal humerus
Fractures extending from the humeral head into the shaft
Cases involving osteoporotic bone where added fixation strength is required
Situations where minimally invasive techniques are preferred to preserve soft tissue and blood supply

How is the MultiLoc™ Humeral Nailing System Performed?

After careful imaging and surgical planning, the patient is positioned to provide access to the shoulder. A small incision is made at the top of the humerus, and the nail is inserted into the bone’s canal under fluoroscopic guidance. The fracture is aligned and fixed with proximal and distal locking screws, ensuring stability. Once the implant is secured, the incision is closed, and postoperative care begins.

What to Expect During Recovery After MultiLoc^TM Nailing System Implantation?

Following surgery, the arm may be supported in a sling for comfort. Gentle, passive shoulder motion often begins within the first day or two, progressing to active exercises as healing allows. Most patients regain strength and motion over several weeks with the help of physical therapy. Full recovery and bone healing typically occur within 10 to 14 weeks.

What are the Risks of the MultiLoc™ Humeral Nailing System?

Malunion or nonunion of the fracture
Implant migration or screw loosening
Shoulder stiffness or impingement
Rotator cuff irritation at the nail entry site
Infection or nerve injury

What are the Benefits of the MultiLoc™ Humeral Nailing System?

Enhanced fixation and stability, even in weak or osteoporotic bone
Reduced soft tissue disruption due to minimally invasive design
Reliable healing and improved functional outcomes
Options to treat both simple and complex shoulder fractures
