Cementless Long-Stem Reverse Total Shoulder Arthroplasty as Primary Treatment for Metadiaphyseal Humeral Shaft Fractures

The use of cementless diaphysis-fitting stems has been shown to be an effective treatment option for cases of metadiaphyseal humeral fracture. Complex metadiaphyseal fractures are those that extend below the surgical neck into the diaphysis, which can compromise the metaphyseal fixation of typical arthroplasty designs. The presently described surgical technique circumvents the potential risks associated with the use of cement while also permitting the treatment of common concomitant pathologies, such as arthritis and rotator cuff tendinopathy. Evidence supports the efficacy of this technique, showcasing consistent rates of healing, pain relief, and functional recovery, as well as acceptable complication rates compared with alternative surgical options.
