In this paper we study the role of incomplete ex ante contracts for ex post trade. Previous experimental evidence indicates that a contract provides a reference point for entitlements when the terms are negotiated in a competitive market. We show that this finding no longer holds when the terms are determined in a non-competitive way. Our results imply that the presence of a "fundamental transformation" (i.e., the transition from a competitive market to a bilateral relationship) is important for a contract to become a reference point. To the best of our knowledge this behavioral aspect of the fundamental transformation has not been shown before.

A periprosthetic fracture is a fracture around or in proximity of a prosthetic implant. As more and more prostheses are implanted, the incidence of periprosthetic fractures also increases. Several risk factors have been outlined, some due to the patient, and some due to the implant itself. Key points in diagnosis are the case history and the imaging, as they allow the distinction between a well-fixed and a loose prosthesis. Correct classification is crucial for the treatment choice, which can be non-operative or consist in an osteosynthesis or in a revision arthroplasty, depending on the patient's general medical condition and the local status.
