Inlay Glenoid
Inlay Glenoid

An inlay glenoid component can minimize the effect of edge loading which has been shown to be a primary cause of failure of onlay glenoids. This is an important consideration when selecting a glenoid component for the younger and more active TSR patient.

The Shoulder HemiCAP® Systems and the The OVO® and OVOMotion™ Shoulder Arthroplasty System w/ Inlay Glenoid restore the articular surface geometry of the humeral head and preserve all of the surrounding joint structures using an innovative 3-dimensional mapping system and a contoured articular resurfacing implant. Our nonspherical humeral implants truly recreate the native anatomy of the Shoulder joint, are proved to reduce pain and improve range of motion. The HemiCAP® Shoulder and OVO™ systems are approved for use in the US and most European markets for the treatment of articular cartilage defects in the shoulder as well as the gleniod.

Some of the clinical conditions that The Shoulder HemiCAP® system & OVO™ Shoulder Arthroplasty Systems are used to treat are:

  • Avascular necrosis (AVN)
  • Hillsachs Lesions
  • Post-traumatic degenerative disease.
  • Osteoarthritis
  • Arthritis

Restoring the shoulder joint with a HemiCAP® or OVO™ implant is an active solution 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 system consists 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 is a stable construct with no reported loosening.

shoulder replacement surgeryInlay Glenoid Features

  • An off the shelf, sterile disposable surgical kit
  • Partial or Full inlay glenoid virtually eliminates overstuffing
  • Glenoid bone preservation permits future onlay options
  • Inlay design is stable and anatomic to avoid loosening
  • Off-axis preparation of the glenoid socket avoids head removal

Surgical Technique

  • The Shoulder HemiCAP® implant system is comprised of two parts, an articular cap and a fixation component. The two components are connected together via morse taper, with zero reported loosening. The instruments are organized in the order of surgery, proceeding from left to right and top to bottom. The technique varies slightly depending on whether a Classic Shoulder HemiCAP® or the OVO™ implant is selected, however the surgical procedure is essentially the same as all other HemiCAP® techniques.
  • shoulder surgeryThe glenoid is prepared off axis, using a 30⁰ angled guide to place a guide wire. Then, through a series of reaming and trialing, the best fit is determined. Once the socket is reamed to the correct depth, tunnels are drilled for the peg holes and perforations are made in the bone bed to improve cement fixation. The cement is then placed and pressurized using a special silicon finger sleeve and then the implant is seated and impacted into place.
  • Once the glenoid is in place, the humeral head implant is seated/ impacted on the taper post. Closure is then completed.

Advantages for the Patient

  • HemiCAP® technology was designed so patients can continue working and retain an active lifestyle without compromising future treatments.
  • Clinical studies demonstrate positive clinical outcomes
  • Patients report pain relief, rapid recovery and a full range of motion
  • The procedure may be performed on an outpatient basis
  • Allows for preservation of bone and soft tissues
  • Maintains existing joint biomechanics, thereby allowing normal motion
  • Patients experience a rapid return to activity for both work and exercise
  • Less bone removal than a total shoulder replacement

Advantages for the Surgeon

  • Intuitive, universal, reproducible procedure across multiple joints
  • The anatomic humeral curvatures and inlay glenoid are designed to eliminate overstuffing which can affect range of motion, overloading and glenoid loosening
  • Minimally invasive/outpatient procedure can be performed in approximately one hour
  • Maintains soft-tissue envelope and native joint mechanics
  • The two components are connected together via morse taper, with zero reported loosening
  • Preserves skeletal anatomy thereby allowing a future total joint replacement

  • Quick Facts

    • There are little to no activity restrictions with the Shoulder HemiCAP®
    • Shoulder HemiCAP® Patients can lift as much as they want truly making it an active alternative to Shoulder replacement
    • HemiCAP® Implants are custom matched and fit to a patient’s joint size and shape. (Custom Implant sizes)
    • Significantly less cartilage and bone is removed than with a traditional stemmed total Shoulder replacement
    • Implant is placed into the bone rather than on top, restoring the joints natural anatomy (Inlay Implant)
    • Allows patients to regain their active lifestyles and daily routines pain-free
    • Your patients will have a shorter recovery time and will be back to work quicker than with a total Shoulder replacement
    • HemiCAP® Shoulder Implants help eliminate Shoulder Patin by resurfacing not replacing the shoulder joint. (Resurface don’t replace)
    • There is no reported loosening between the cap and taper post
    • Stay active with the Arthrosurface HemiCAP®
    • Allows patients to maintain high-level physical activities and lifestyles.
    • Inlay implants are inherently more stable than onlay implants.
    • Shorter recovery time and back to work quicker than a total joint replacement
    • The Shoulder HemiCAP® implants don’t overstuff the joint like a traditional total shoulder replacement
    • Alternative to total shoulder replacement
