Schnetzke M, Jung MK, Groetzner-Schmidt C, et al. - This study was intended to present functional outcomes, to evaluate complications, revisions, and survival rate, and to examine variations in functional outcomes between removed and retained radial head replacements (RHAs), early and delayed treatment, and type of RHA used at long-term follow-up after monopolar RHA for unreconstructible radial head fractures or their sequelae. Between 1994 and 2010, 78 patients (mean age 59.2 years) that were at least six years postoperatively following monopolar RHA for unreconstructible RHFs or their sequelae and were included. Researchers assessed Mayo Elbow Performance Score, Quick Disability of the Arm, Shoulder and Hand score, the Visual Analog Scale, postoperative satisfaction (1-6, 6=highly unsatisfied), range of motion, complications, and revisions. They compared subgroups (RHA type, early vs. delayed surgery, RHA removed vs. retained). The study found satisfactory long-term outcomes for RHA; nevertheless, there is a high complication and revision rate, implying in implant survival of 75.1% at 18 years with the highest annual failure rate found in the first postoperative year.
