A RARE CASE OF IRREDUCIBLE LATERAL SUBTALAR DISLOCATION WITH POSTERIOR TIBIALIS TENDON ENTRAPEMENT

Ayoub Boushabi*, Hicham Aitbenali, Mohammed Shimi

ABSTRACT

Pure acute external subtalar dislocation due to incarceration of the posterior tibial tendon is a very rare lesion. The external variant is exceptional. Medial astragalo-scapho-calcaneal dislocation is defined as a loss of anatomical relationship between the astragalus, calcaneus and scaphoid, but tibio-peroneo-astragalar congruence is maintained. The diagnosis is initially clinical, confirmed by X-rays of the foot and ankle, but a three-dimensional CT scan provides a complete assessment of the lesions, looking for associated osteocartilaginous lesions, to determine the therapeutic orientation and surgical planning. The reduction must be performed urgently under anesthesia. If orthopedic reduction proves impossible, surgical treatment can achieve anatomical reduction by removing obstacles in cases of irreducibility or coercibility, and osteosynthesis in the case of associated fractures. By intervening quickly we can often prevent or minimize the complications that can arise following the dislocation. We report the case of a young patient with a subtalar dislocation caused by incarceration of the posterior tibial tendon, who was treated in our structure.
