Tornier Flex Shoulder System
The two most common types of total shoulder replacement are primary total shoulder replacement and reverse total shoulder replacement. Tornier Flex features a convertible short-stem and can be used for primary or reverse total shoulder replacement.
Bone preservation
Tornier Flex features a curved short stem that is designed to mimic the internal geometry of the humerus (arm bone). The curved short stem preserves more bone than a traditional length stemmed implant while also providing structural support necessary for implant stability.1
Simplified conversion
Tornier Flex is an innovation in shoulder replacement design that gives your orthopaedic surgeon the flexibility to address your current shoulder condition while considering potential future conditions. Should a conversion from a primary total shoulder to a reverse total shoulder be required, Tornier Flex features a convertible stem which allows for a simplified conversion. The already well-fixated stem remains in place while the components on top of the stem are exchanged.
When are conversions necessary?
In a well-documented study, 90% of shoulder replacement implants were still in place at ten years and 81% at twenty years.2 The length of time shoulder replacement implants last is highly dependent upon many factors including age, weight, activity level, sustained injury, healing rate, infection, rotator cuff function, overall health, and other factors. A revision surgery or conversion from a primary to a reverse total shoulder replacement may be required due to natural thinning of the rotator cuff and loss of rotator cuff function, injury to the shoulder and implant wear or loosening.

Shoulder replacement
Anatomic total shoulder joint replacement is intended for use in individuals with painful, disabling joint disease of the shoulder resulting from: degenerative arthritis, rheumatoid arthritis or post-traumatic arthritis. Additional indications could include but not limited to: aseptic necrosis of the humeral head, proximal humeral fracture and revision of previous unsuccessful hemiarthroplasty or other procedures.
Reverse total shoulder joint replacement is intended for use in individuals with a functional deltoid muscle and with massive and non-repairable rotator cuff tear with pain disabled by: rheumatoid arthritis, non-inflammatory degenerative joint disease, humeral head fracture, traumatic arthritis and revision of devices if adequate bone stock remains.
Shoulder joint replacement surgery is not appropriate for patients with any active or suspected latent infection in or about the shoulder joint, any mental or neuromuscular disorder which would create an unacceptable risk of prosthesis in stability, prosthesis fixation failure or complications in postoperative care. Additionally, shoulder joint replacement surgery is not appropriate for patients whose anticipated activities would impose high stresses on the prosthesis and its fixation.
As with any surgery, shoulder joint replacement surgery has serious risks which include, but are not limited to, pain, infection, intraoperative complications, component wear, nerve damage, loosening of shoulder components and dislocation of the shoulder prosthesis.
Implant related risks which may lead to a revision or removal of the implant include being overweight, manual labor activities, some sports activities, patient age, activity level, medical conditions, alcohol or drug addiction, and mental disorders. Shoulder joint implants may not provide the same feel or performance characteristics experienced with a normal healthy joint
The information presented is for educational purposes only. Speak to your doctor to decide if joint replacement surgery is appropriate for you. Individual results vary and not all patients will return to the same activity level. The lifetime of any joint replacement is limited and depends on several factors like patient weight and activity level. Your doctor will counsel you about strategies to potentially prolong the lifetime of the device, including avoiding high-impact activities, as well as maintaining a healthy weight. It is important to closely follow your doctor’s instructions regarding post-surgery activity, treatment, and follow-up care. Ask your doctor if a joint replacement is right for you.
