Non-anatomical Monopolar Uncemented Radial Head Arthroplasty: Surgical Technique and Expected Outcomes

  • Davide Blonna

Non-anatomical monopolar uncemented radial head arthroplasty is one of the most commonly performed radial head arthroplasties and is one of the first radial head replacements with a well-documented long-term follow-up. These designs behave as a spacer and are based on the concept that a real anatomical replacement of the radial head is not achievable due to the extreme anatomical variability. With a proper learning curve and precise surgical technique, good medium- to long-term follow-up should be expected. A common complication seems to be the radiolucency around the stem that, however, does not correlate with clinical symptoms.
