[Radial head arthropolasty in unreconstructable comminuted fractures of the radial head: Long-term results and factors influencing the outcome].

Radial head arthroplasty is an effective treatment option for unreconstructable fractures of the radial head and can provide good to excellent mid-term to long-term results. Sustained elbow dislocation as well as overlengthening of the prosthesis had a negative impact on the clinical outcome.
