Clinical Trial Summary

The purpose of the study is to describe the rate of bone fusion (radiological consolidation) in the 2 groups (A and B) 4 months after the operation.

Description:

The main objective of the study is to describe the rate of bone fusion obtained with the different types of osteosynthesis material: dorsal plate, large-diameter compression screw.

Patients will be divided into two groups:

• patient undergoing arthrodesis of the hallux with a large diameter screw (group A)

• patient undergoing arthrodesis of the hallux by plate (group B)

This is a prospective, cross-sectional, open, comparative, non-randomized, non-interventional, monocentric study on two methods of synthesis (large-diameter plate or screw) of hallux metatarsophalangeal arthrodesis. Patients will be managed in accordance with current practice, the choice of surgical strategy (percutaneous / open) being left to the discretion of the investigators.
