“…Furthermore, this device allowed good mobility recovery. More recently, Sasanuma et al [ 76 ] compared the clinical results of the use of nonporous and porous Ta prostheses for treating humerus proximal fractures in 41 elderly subjects. Porous devices evidenced much better performances, allowed greater ranges of motion for the shoulder, and exhibited higher osseointegration level.…”

During the last 20 years, tantalum has known ever wider applications for the production of endosseous implantable devices in the orthopedic and dental fields. Its excellent performances are due to its capacity to stimulate new bone formation, thus improving implant integration and stable fixation. Tantalum’s mechanical features can be mainly adjusted by controlling its porosity thanks to a number of versatile fabrication techniques, which allow obtaining an elastic modulus similar to that of bone tissue, thus limiting the stress-shielding effect. The present paper aims at reviewing the characteristics of tantalum as a solid and porous (trabecular) metal, with specific regard to biocompatibility and bioactivity. Principal fabrication methods and major applications are described. Moreover, the osteogenic features of porous tantalum are presented to testify its regenerative potential. It can be concluded that tantalum, especially as a porous metal, clearly possesses many advantageous characteristics for endosseous applications but it presently lacks the consolidated clinical experience of other metals such as titanium.

“…Along with implant characteristics, several fixation techniques have been developed to impart satisfactory reattachment of the tuberosities [31,[74][75][76][77]. Some studies have focused on stem-based fixation of tuberosities [30,75,78] while others have explored bone grafting [32,33,[79][80][81] and suture techniques [74,77,82] to secure the tuberosities to the humeral stem. Cemented humeral fixation has not improved tuberosity healing, but has led to worse patient-reported outcomes [83,84].…”

Prosthesis Designs and Tuberosity Fixation Techniques in Reverse Total Shoulder Arthroplasty: Influence on Tuberosity Healing in Proximal Humerus Fractures

Reverse total shoulder arthroplasty (RTSA) is increasingly used for the treatment of complex proximal humerus fractures and fracture sequelae. In 2021, half a dozen models of fracture stems are commercially available, reflecting its growing utility for fracture management. Prosthesis designs, bone grafting and tuberosity fixation techniques have evolved to allow better and more reliable fixation of tuberosities and bony ingrowth. Patients with anatomical tuberosity healing not only have an increased range of active anterior elevation and external rotation, but also experience fewer complications and longer prosthesis survival. This review provides an overview of recent evidence on basic and fracture-specific RTSA design features as well as tuberosity fixation techniques that can influence tuberosity healing.
