Treatment of checkrein deformity of the hallux

Abstract

We studied 11 patients with checkrein deformities of the hallux who underwent surgical treatment. Six had lengthening of the flexor hallucis longus tendon by Z-plasty in the midfoot, and five underwent release of adhesions and lengthening of the tendon by Z-plasty at the musculotendinous junction at the fracture site. All six patients who underwent Z-plasty at the midfoot showed complete correction of the deformity without recurrence. Of the five who had release of adhesions and Z-plasty of the tendon at the fracture site, two showed partial and one showed complete recurrence.
