Successful hemiarthroplasty for fracture requires healing of the tuberosities. When this doesn’t occur, results are universally poor.1 An alternate solution in patients at risk for tuberosity healing, especially in the elderly, is the reversed prosthesis. A reversed shoulder system in these specific cases can offer more predictable results and deliver the best possible outcome for the patient.
Tornier offers the Aequalis™ Reversed Fracture Shoulder Prosthesis, designed specifically for three- and four-part humeral fractures.
Because successful patient outcomes rely on proper fracture healing, surgeons need to rely on a shoulder prosthesis that is specifically designed to address this clinical need. With Tornier’s Reversed Fracture prosthesis, patients can enjoy improved functional results through better tuberosity reduction, and fixation of the tuberosities, along with increased opportunity for osteointegration.
In one study of 38 patients, a greater level of predictability in results was demonstrated when Reversed Total Shoulder arthroplasty was used for proximal humeral fractures.

Hemiarthroplasty for acute fractures can be a viable option; however, consistent results are not always achieved.
More predictable and consistent results in AAE were achieved with reversed for fracture. Better results were correlated with greater tuberosity healing.
As shoulder fracture treatments have improved, patients have been able to count on more mobility and less pain. A critical factor in achieving optimal results is tuberosity healing for three- and four-part fractures. The primary complication that leads to poor results is healing of the greater tuberosity. When tuberosity healing does not occur, patient outcomes can be compromised.2
Hemiarthroplasty for proximal humeral fractures has remained as a viable treatment choice for years. More recently, the Reversed Total Shoulder Arthroplasty procedure has rapidly gained acceptance for treating more complex humeral fractures. With the reversed approach, more consistent patient results have been observed.

The stem is also recommended for revision cases where bone quality is compromised.
