Clinical examination showed grade 1 swan neck deformity as per Nalebuff classification affecting the left ring and middle fingers [Figures 1 and 2].
Vicryl suture passed twice with intervening soft tissue. Figure shows lax volar plate

Clinical examination showed grade 1 swan neck deformity as per Nalebuff classification affecting the left ring and middle fingers [Figures 1 and 2]. The Vicryl suture was passed from distal to proximal direction taking bites of approximate 5 mm of the volar plate twice [Figure 2].
Transverse furrow can be seen in the middle part of the volar plate due to volar plate shrinkage subsequent to tying of both vicryl suture knots. Flexor digitorum superficialis and flexor digitorum profundus have been retracted towards the radial side

When the sutures were tied, it led to shrinking of the volar part of the PIP joint [Figure 3] keeping the PIP joint in 30  flexion.

Multiple sutures using nonabsorbable Number 3-0 prolene suture were taken to tie the FDS tendon and also to secure the FDS tendon to A2 pulley [Figure 4].

Dynamic traction was provided by rubber band between fingertips and volar aspect of the wrist to maintain the involved digits' flexion to further relax and also to prevent inadvertent active flexion of the tendon [Figure 5].
