Active motion of the ring finger at the first visit to our
institution. Total active motion (TAM) was 168 . (A) full
extension. (B) limited flexion of the distal interphalangeal (DIP)
and proximal interphalangeal (PIP) joints.

The total active motion (TAM) was 168  (percent TAM, 62%) (Fig. 1).
The distal stump of the flexor digitorum profundus tendon
is frayed and degenerated. The proximal stump is swollen and
degenerated. FDP: flexor digitorum profundus,

Frayed and degenerated distal stump and enlargement of the swollen proximal stump of the FDP tendon were noted (Fig. 2).
The flexor tendon of the second toe was bridged between
the distal phalanx and the proximal stump of the flexor digitorum
profundus (FDP) tendon of the ring finger. The shape and glistening
appearance of surface of the grafted tendon are similar to those of
the original FDP tendon.

For the proximal juncture, 3 weaves of the grafted tendon were applied to the proximal stump of the FDP tendon (Fig. 3).
Magnetic resonance imaging of the ring finger before tenolysis. (A) T1-weighted sagittal view showing the grafted flexor tendon
with low signal intensity. Cross-sectional view of the ring finger at the level of the proximal phalanx (B) and middle phalanx (C). The crosssectional
area of the grafted flexor tendon was similar to that of the adjacent digit.

Magnetic resonance imaging (MRI) of the ring finger revealed that the configuration of the grafted tendon was almost normal (Fig. 4).

The appearance of the graft tendon from the second toe was normal, without apparent degenerative findings (Fig. 5).
Active motion of the ring finger at 1.5 years after
tenolysis. Note the nearly full extension (A) and flexion (B). TAM
was 268 .
