The synovial tissue was peeled off carefully and each tendon was separated. The intratendinous ganglion was herniated from the slit of the tendon substance of the EDC III. The extensor retinaculum had been partially cut and separated.

The synovial tissue was peeled off carefully and each tendon was separated, then the intratendinous ganglion was identified within the tendon substance of the EDC III and a part of the ganglion was herniated from the slit of the tendon substance (Figure 1).
The ganglion was excised with a small portion of the tendon substance attached.

Hence, to remove the ganglion completely, the ganglion was excised with a small portion of the tendon substance attached (Figure 2).

Intraoperative findings. The FDS tendon of the ring finger was swollen in a fusiform-shape just proximal to the A1 pulley (arrow) and moderate tenosynovitis around the FDS tendon existed.

Surgical exploration revealed an intratendinous ganglion of the FDS tendon just proximal to the A1 pulley (Figure 3).
Gross specimen of the resected FDS tendon including the ganglion. The expanded tendon with ganglion was covered with proliferative synovial tissue and the content was observed between the cleft of the tendon substance.

FDP tendon was observed, moderate tenosynovitis around the FDS tendon existed. Fearing recurrence of the ganglion resulting from incomplete resection or postoperative subcutaneous rupture of the tendon, on account of structural weakness resulting from excessive resection, en bloc excision of the FDS tendon including the ganglion was performed (Figure 4).
