What researchers measure

Primary outcomes

  1. Difficulties of the procedure [feasibility of the procedure]

    Time frame: per-operative

  2. Type of anaesthesia [feasibility of the procedure]

    Record the type of anaesthesia as GA (General Anaesthesia), local anaesthesia + sedation, or other.

Individual participant data

Plan to share: Yes — The data analysis of the investigation will carry out a final report that will be sent to the CPP and ANSM. According to the law N°2002-303 dated March 4, 2002, the patients involved in the study will be informed on demand on the global data analysis. Regarding publication, if the data analysis provides important and interesting information on the device and its associated procedure for the treatment of vertebral compression fracture which aims to complete the state of the art, it may be decided to publish the corresponding data. In this case, the IPD that will be shared will consists of all IPD that underlie results in this publication.
