Olecranon fractures in young people are commonly treated surgically. When a transverse pattern is presented the most used method to fix the fracture is the Tension Band Wiring. The AO Foundation proposed a theory for the mechanism of action of this device. It could transform the tensile forces on the posterior side into compression forces on the joint side during flexion of the elbow. Our objective is to systematically review the available literature in order to confirm or not this hypothesis. We will include biomedical research studies evaluating Tension Band Wiring function. We are planning to search on Medline, Embase and other sources including grey literature. The studies will be selected and the data extracted. Results will include a descriptive analysis and a meta-analysis to compare the observed compression force before and after the flexion of the elbow. Our findings will be discussed having in mind the potentially clinical implications of results.

Not funding resources received

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines and uploaded the relevant EQUATOR Network research reporting checklist(s) and other pertinent material as supplementary files, if applicable.

Yes

This is a Protocol for a Systematic Review. There is not any new data yet.
