RECURRENT DISLOCATION OF TIBIALIS POSTERIOR TENDON - A REPORT OF 2 CASES

We successfully treated two patients with recurrent dislocation of the tibialis posterior tendon by creating a bone block, Sudden resistive contraction of the tibialis posterior muscle is considered to be the m echanical cause of the initial traumatic injury, and a shallow tibiali s posterior tendon sulcus may be the predisposing factor, Once the fle xor retinaculum is torn during the initial trauma, recurrent dislocati on is inevitable, and surgical treatment is mandatory. When treating p atients with a complaint of long-standing pain around the medial malle olus, we must bear in mind the possible diagnosis of recurrent disloca tion of the tibialis posterior tendon. If the patient can voluntarily dislocate the tendon by active plantar flexion and inversion of the an kle, the diagnosis is definitive.
