The purpose of this study was to investigate which factors predict the failure and success of treatment of periprosthetic type B humeral fractures that have occurred traumatically.


The institutional admission database and the trauma registry were retrospectively reviewed. A total of 8 patients suffering from periprosthetic humeral fractures were included. The time span was 10 years (2000–2010).


The average age at the time of the fracture was 77 years. Surgery was performed at an average of 5.6 days after injury. In three patients with a well-fixed and one with an unstable humeral component, open reduction and internal fixation with the use of a plate and screws was performed. Two patients with a Delta prosthesis had an unstable humeral component. A proximal humeral resection and an implantation of an HMRS prosthesis was performed in one patient. The other patient received a Delta revision stem prosthesis, cable and plate fixation. Two patients were treated conservatively.


Early surgical treatment with angular stable implants in fractures with a stable stem and replacement with a revision long-stem component in fractures with a loose prosthesis is recommended. Special attention should be paid to bone quality and anatomical proximity to the radial nerve. Conservative treatment of type B fractures is not sufficient to achieve union, especially in short oblique or transverse fractures.
