(a) Anteroposterior and (b) lateral radiographs demonstrating irreducible dislocation of interphalangeal joint of hallux, sesamoid was entrapped within joint.

IPJ of right hallux. In addition, sesamoid was observed as entrapped within the IPJ (Figure 1).
(a) A stab incision performed on dorsomedial side of joint. (b) Sesamoid-plantar plate complex was pushed with blunt side of K-wire by hand under fluoroscopic guidance.

Then, the blunt side of a 1.5 mm K-wire was introduced into the IPJ through the incision (Figure 2a). The sesamoid-plantar plate complex was pushed with the blunt side of the K-wire by hand under fluoroscopic guidance (Figure 2b, Figure 3).
An illustration demonstrating percutaneous reduction technique. Blunt side of a 1.5 mm K-wire was introduced into interphalangeal joint of hallux through incision performed on dorsomedial side of joint. Sesamoid-plantar plate complex was pushed gently with blunt side of K-wire by hand until sesamoid-plantar plate complex was reduced to its original location.

The sesamoid-plantar plate complex was pushed with the blunt side of the K-wire by hand under fluoroscopic guidance (Figure 2b, Figure 3).
Reduction of interphalangeal joint of hallux was confirmed with fluoroscopy on (a) anteroposterior and (b) lateral views.

However, the IPJ was clinically unstable thus temporary arthrodesis was performed to the IPJ with a K-wire (Figure 4).
(a) Anteroposterior and (b) lateral radiographs of interphalangeal joint of hallux showed good alignment with congruent joint at sixth week of follow-up.

At sixth week of follow-up, radiographs of his right IPJ showed good alignment with congruent joint (Figure 5) thus K-wire was removed.
