Abstract
Purpose: The aim of this study was to assess functional and radiological outcomes of radial head arthroplasty (RHA) compared to open reduction and internal fixation (ORIF) in isolated Mason type-III fractures with a minimum of five years follow-up.
Methods: This was a retrospective single-center study of closed isolated Mason type-III radial head fractures operated between January 2008 and December 2017. Nineteen patients were included in group RHA and 35 patients in group ORIF. The mean age was 51 years old in group RHA and 41 years old in group ORIF (p = 0.02). Functional and radiological outcomes were evaluated.
Results: Mean follow up was eight years (range, 5-14). Clinical results and functional scores showed no significant differences, except a better pronation in group RHA (p = 0.04). Two secondary radial head resection or implant removal were performed in each group (p = 0.56) with poor functional outcomes in group ORIF. There was less heterotopic ossification in group RHA (15.8% vs. 42.8%; p = 0.03). Capitulum wear was found in 63% in group RHA against 25.7% in group ORIF (p < 0.05).
Conclusion: Functional results of RHA and ORIF were comparable for isolated Mason type-III fractures at a mean follow-up of eight years. We recommend to perform RHA for isolated Mason type-III fracture if articular reduction or stability of the fixation is not satisfying.
期刊介绍：
International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters.
Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable.
The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
