NCT05101499

Brief Summary

We hypothesize that the Akin screw fixation osteotomy technique provides better postoperative mobility of the metatarsophalangeal hallux joint compared to the non-fixation technique.

Outcome Measures

Primary Outcomes (1)

  • Overall mobility of the metatarsophalangeal hallux joint in degre

    Overall mobility of the metatarsophalangeal hallux joint in degree, one year after surgery, measured by a goniometer, as the amplitude between plantar flexion and dorsiflexion.

    1 year

Study Arms (2)

AKIN osteotomy with screw fixation

EXPERIMENTAL
Procedure: AKIN osteotomy with screw fixation

AKIN osteotomy without screw fixation

ACTIVE COMPARATOR
Procedure: AKIN osteotomy without screw fixation

Interventions

A simple skin speck is made on the medial aspect of the hallux, in the metaphyseal area, using a 3 mm beaver blade. The tissue is lifted from the bone using an elevator medially and dorsally on the phalanx. A Shannon 2x12 mm burr is then positioned transversely by making the osteotomy which must preserve a lateral hinge, a guarantee of stability in the event of non-fixation. Fixation with a screw will be effected by another skin speckle allowing access to the infero-medial area of the phalangeal base. A pre-hole can be made with the same bur to facilitate the introduction of the guide wire for osteosynthesis, which is not specific.

AKIN osteotomy with screw fixation

This is the same procedure as the procedure under study, without the fixation by a target: a simple skin speck is performed on the medial face of the hallux, in the metaphyseal area using a beaver blade. of 3 mm. The tissue is lifted from the bone using an elevator medially and dorsally on the phalanx. A Shannon 2x12 mm burr is then positioned transversely by making the osteotomy which must preserve a lateral hinge, a guarantee of stability in the event of non-fixation.
