“…Studies looking at the metallic head prosthesis have showed evidence of implant loosening, head disassociation from the stem and post‐operative arthrosis. These same studies have commented favourably on the low revision rate of these implants and on the modularity of the metallic prosthesis, which has allowed the prosthesis to be placed with ease …”

Background: Comminuted radial head fractures are challenging to treat with open reduction and internal fixation. Radial head arthroplasty is a favourable technique for the treatment of complex radial head fractures. The purpose of this study was to evaluate the functional and radiological outcomes of radial head arthroplasty using modular pyrocarbon radial head prosthesis. Methods: We retrospectively reviewed 21 consecutive patients requiring radial head arthroplasty for unreconstructible radial head fractures between July 2003 and July 2009. Patients completed a Short Form-36 (SF-36), the Disabilities of the Arm, Shoulder and Hand questionnaire, and the Mayo Elbow Performance Index. Patients were independently physically examined and their post-operative radiographs were reviewed. Results: Twenty-one patients (nine males and 12 females) were reviewed at a minimum of 12 months follow-up. The mean Disabilities of the Arm, Shoulder and Hand score was 10.8 (0-34.1), mean SF-36 physical score was 76.9 (35-96), mean SF-36 mental score was 83.8 (60-94), and their Mayo Elbow Performance Index score was 86.4 (70-100). Patients maintained 90% of their grip strength when compared with their uninjured arm and had 17.5°of fixed flexion in the affected arm. Radiologically, 14 cases had some degree of post-traumatic osteoarthritis, 12 cases had evidence of heterotrophic ossification, five had some evidence of periprosthetic lucency and three patients were radiologically, but not functionally 'overstuffed'. Conclusion: Radial head arthroplasty with pyrocarbon radial head prosthesis is an acceptable option when treating unreconstructable radial head fractures yielding good functional and radiological outcomes.

“…[13][14][15] However, a prosthesis may have its inherent drawbacks such as overstuffing, osteolysis, loosening, or implant dislocation. [16][17][18] If we can get acceptable functional outcomes with low complication rate, ORIF is preferable to preserve normal articulation and bone stock. If ORIF fails prematurely, theoretically it can be converted into RHA.…”

The objective of this study was to investigate whether the outcomes of Mason type III radial head fractures (RHFs) treated by open reduction and internal fixation (ORIF) were comparable to those of Mason type II RHFs treated by ORIF. Methods: A total of 87 surgically treated RHF patients were reviewed. Their fractures were Mason type II in 39 patients (all treated by ORIF) and Mason type III in 48 patients (40 treated by ORIF, 7 by radial head arthroplasty, and 1 by resection). Although ORIF was preferred for Mason type III RHFs in our series, an arthroplasty was performed when the fracture accompanied severe associated injuries or multiple traumas. Radiological and functional outcomes were evaluated and complications were reviewed. Results: When Mason type II and Mason type III in general were compared, QuickDASH score, a shortened version of the Disabilities of the Arm, Shoulder and Hand (DASH) score, and forearm rotation were significantly worse in Mason type III. However, when comparing Mason type II and Mason type III treated by ORIF in which the proportion of associated injuries were not significantly different, there was no significant difference in QuickDASH score, range of extension/flexion, or complication rate. Forearm rotations were significantly more limited in Mason type III treated by ORIF (7 for pronation and 7 for supination), and Mason type had an independent effect on forearm rotations in multivariate analysis. Conclusion: ORIF for Mason type III fractures with low level of associated injury can be as good as that for Mason type II fractures, except for less forearm rotation.
