Summary
A modular humeral hemiarthroplasty disarticulated after surgery due to its taper-lock design. This case report details the failure of this specific prosthetic component in rotator cuff arthropathy treatment.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Materials Science
Background:
- Rotator cuff arthropathy often necessitates surgical intervention, with hemiarthroplasty being a common treatment option.
- Modular prosthetic designs offer surgical flexibility but may present unique failure modes.
- Taper-lock mechanisms are employed in some modular implants for secure component fixation.
