“…Our results are comparable to those after implantation of other modern types of prostheses [8,18,25]. In 30 patients with implantation of a newly designed bipolar RHP with a mean follow-up of 34 months the MEPS averaged 92.1 points [25].…”

Purpose Dislocations of components, loosening of the stem, overstuffing and removal in up to 24 % of common radial head prostheses (RHP) after implantation in complex elbow injuries signal the need for improvement. The latest biomechanical evidence shows advantages for monopolar designs. Clinical results after primary and secondary implantation of the newly designed press-fit monobloc monopolar RHP in cases of complex elbow injury are evaluated. Methods Twenty-nine patients [median age 60 years (29-86)] were followed up retrospectively for a median of 25 months (7-54) post-operatively. Subjective parameters, the Mayo Elbow Performance Score (MEPS), the Broberg and Morrey score (BMS), latest radiographs and complications were evaluated. Results MEPS and BMS averaged 87.2±12.9 and 81.1±11.9 points, respectively. No case of implant loosening was observed; the RHP had to be removed in one case (3 %). The overall complication and revision rate was higher after secondary (53 %) than after primary (19 %) implantation. Conclusions Satisfactory clinical results and low short-term removal rates emphasise the practicality of monobloc monopolar RHP. Differentiated treatment of complex elbow fracturedislocations is compulsory to avoid the need for secondary RHP implantation which carries a higher complication rate.

“…Der Kopf besteht dabei aus Pyrocarbon, welches in seinen biomechanischen Eigenschaften dem Knochen beziehungsweise Knorpel sehr ähnlich ist und dadurch ein Aufbrauchen des korrespondierenden Capitulumknorpels vermeiden soll [18]. Die Datenlage zu Ergebnissen nach Implantation der MoPyC-Radiuskopfprothese ist bisher begrenzt.…”

“…Die Datenlage zu Ergebnissen nach Implantation der MoPyC-Radiuskopfprothese ist bisher begrenzt. Sarris et al [18] präsentierten 2012 eine retrospektive Studie, in der 32 Patienten nach Implantation einer MoPyC-Prothese nachuntersucht wurden. Das mittlere Followup betrug dabei 27 Monate und schwankte von 21 bis 46 Monaten.…”
