Shoulder Implants

Some of the clinical conditions that The Shoulder HemiCAP® system and the OVO Primary Stemless Shoulder System with Inlay Glenoid are used to treat are:Avascular Necrosis (AVN)

  • Hillsachs Lesions
  • Post-traumatic degenerative disease
  • Osteoarthritis
  • Arthritis

Stemless Total ShoulderRestoring the shoulder joint with the HemiCAP® implant or the OVO Primary Stemless Shoulder System, is truly an active alternative to a total shoulder replacement. The idea behind the Shoulder Implant systems is to prevent further damage to the joint while maintaining the patient’s native anatomy, motion and activity level. The systems consist of a cap (implant) and screw that mate together via taper lock. The implants match the diameter of the damaged area as well as the precise radius of both curvatures on the shoulders’ surface, superior to inferior (top to bottom) and medial to lateral (side to side). The Arthrosurface® screw system for minimally invasive shoulder surgery is a stable construct with no reported loosening.

In addition to the smaller sizes of the Shoulder HemiCAP®, The OVO Primary Stemless TotalShoulder is indicated for patients with advanced arthritis. The OVO Primary Stemless Implant in conjunction with the HemiCAP GRS Inlay Glenoid implant (Inlay means that it is implanted into the bone rather than on top, leaving natural bone to support the implant around its edges), helps preserve most of the bone in your shoulder while also fixing the damage to your glenoid. Unlike a total shoulder replacement, The OVO does not use a full metal stem but rather a smaller screw (taper post). The OVO simply places a smooth metal surface on the humeral head where the cartilage has worn away and places the plastic glenoid implant on the opposing side (Pictured Right). This system does not limit any future weight bearing activities, such as lifting your children or weights and allows you to resume a normal, active lifestyle.

Over 70,000 patients have been treated with Arthrosurface® implants since 2003, with the majority still implanted over 10 years later.shoulder implants

Am I a Shoulder HemiCAP® Candidate?

Typically, an Arthrosurface shoulder restoration procedure is for someone who has been told by their doctor or orthopaedic surgeon that they have damaged cartilage and/or an arthritic shoulder. After trying non-operative treatments, such as steroid (cortisone) injections, physiotherapy, pain and anti-inflammatory medications, the pain relief is not receding. Now, the pain is serious enough that it is affecting your daily activities, your ability to work out and even your sleep. Most likely, you have been told that your next option is a total shoulder replacement but you don’t want a procedure that will restrict your active lifestyle.

  • Aged 35 to 75 years old
  • Want to regain your active lifestyle
  • You have had a microfracture treatment and/or injections, but the pain has returned
  • You cannot afford lengthy rehabilitation time or excessive time off work
  • You want to fix your shoulder problem now versus waiting for further damage
  • Your surgeon has told you that you will need a shoulder replacement in the near future

*Seek professional medical advice for specific personal care.

How is the Shoulder HemiCAP® & OVO Primary Stemless Shoulder System with Inlay Glenoid different than other existing devices?

  • Little to no activity restrictions creates an active alternative to shoulder replacement
  • It is custom matched and fit to a patient’s joint size and shape
  • Significantly less cartilage and bone is removed than traditional joint replacements
  • It is placed into the surface rather than on top, leaving the joint less surgically altered
  • Joint motion and the native structures are preserved so no bridges are burned

With the Arthrosurface® Joint Restoration System, the surgeon only resurfaces the damaged area, similar to the way a dentist fills in a cavity. This leaves the rest of the structures in your joint intact so your native anatomy is preserved. The exposed and painful bone is covered while all the structures in your joint help you move and function properly are left in place. This differs from a total joint replacement which removes the entire head of the humerus, the rotator cuff and significant amounts of bone from the glenoid resulting in compromised supporting tissues.

Surgery and Recovery Expectations

Patients report outstanding pain relief, rapid recovery times and significant range of motion improvements in multi-center studies and the procedure may be performed on outpatient basis.

shoulder painEvery surgery has risks and your prospects for a safe and successful surgery must be evaluated with your surgeon. If you are affected by osteonecrosis or cartilage damage caused by a previous injury, a successful joint restoration procedure may significantly improve your quality of life by reducing pain and restoring function. Many patients return to full activity after rehabilitation and go back to doing things that they had given up on in the years before surgery.

After the surgical repair of a joint, your surgeon will provide you with specific post-operative instructions which you need to follow carefully. Post-operative rehabilitation recommendations will vary depending on the invasiveness of your surgery and your individual recovery patterns.  The immediate focus in all surgeries will be on swelling and pain management.  In some cases you may wear a brace for a few weeks and will be prescribed exercises and activities to strengthen your muscles.

shoulder pain remedHere are a few helpful suggestions as you recover and rehabilitate from your surgery:

  • Follow the recommendations of your surgeon and physical therapist.
  • Keep a log to track your progress as you recover and increase activity.
  • Ask for assistance from family and friends to help with chores and errands during your recovery.
  • Wear loose, comfortable clothing during your recovery period.
  • Eliminate possible tripping hazards in your home – wires, cables, rugs, etc.
  • Return to any moderate or demanding activities should be guided by your tolerance for weight bearing.
