Which of the following is a consideration when selecting a prosthesis for TSA?

Selecting a prosthesis for total shoulder arthroplasty involves careful consideration of the patient's individual anatomy and functional needs, making the patient's shoulder morphology and joint stability a critical factor. The unique structure of the shoulder, including bone shape, size, and existing deformities or abnormalities, significantly influences the choice of prosthetic components. Achieving a proper fit is essential for optimal biomechanics, range of motion, and joint stability after surgery. For example, variations in glenoid and humeral head geometry may necessitate different implant designs to accommodate the patient's specific needs and ensure a successful surgical outcome.

In addition, understanding the joint's stability is vital, as factors such as rotator cuff integrity and the presence of arthritis can affect both the selection of the prosthesis and the overall surgical approach. By aligning the implant with the patient's anatomical requirements, surgeons can enhance the likelihood of durability, proper function, and minimized complications post-operatively.
