Lasso stitch with peroneal retinaculoplasty for repair of fractured os peroneum: a report of two cases.

UNLABELLED

Fracture of the os peroneus with retraction of the peroneus longus tendon can lead to weakness, instability, and progressive foot deformity. Treatment recommendations vary and include simple immobilization, repair of the fractured ossicle, excision of part or all of the fractured ossicle with repair of the tendon and tenodesis with the peroneus brevis tendon. We present two patients treated with excision of the proximal fragment and repair of the tendon to the distal fragment with relief of pain and restoration of function. The distal fragment was captured with a looped suture which allowed avoidance of a plantar exposure while still achieving an adequate repair. We also describe a technique for retinaculoplasty of the inferior peroneal retinaculum which we believe important to prevent postoperative adhesions to the tendon.
