(a) Forelimbs without constraint demonstrating the presence of a carpal flexural deformity secondary to muscle contracture. A certain degree of valgus deviation is present due to hyperflexion of the carpus and digits, more pronounced in the left (L) forelimb and (b) forelimbs during stance, demonstrating an abnormal carpal flexion that is more pronounced in the left forelimb. R = right

The cat was reluctant to move, and a carpal flexural deformity (CFD) with a certain degree of distal valgus deviation, which was more pronounced on the left side, was noted (Figure 1).
Orthogonal radiographs of both forelimbs demonstrating the presence of a carpal flexural limb deformity with a certain degree of valgus deviation of the distal extremities starting from the carpal joint and hyperflexion of the digits. (a) Dorsopalmar radiograph of the left forelimb; (b) lateral radiograph of the left forelimb; (c) dorsopalmar radiograph of the right forelimb; and (d) lateral radiograph of the right forelimb

Orthogonal radiographs of both forelimbs demonstrated a valgus deviation of the distal extremities (Figure 2).
Intraoperative photograph before a tenectomy of the flexor carpi ulnaris muscle tendon of the right forelimb was performed. A palmaromedial to palmarolateral approach was used just proximal to the antebrachiocarpal joint. The tendon of the flexor carpi ulnaris muscle is highlighted with the surgical instrument

Intraoperative visualisation of the small skin incisions made at the palmar surface of the second phalanx of the third and fourth digit of the right forelimb, allowing for selective tenectomy of the tendon branches of the deep digital flexor muscle (elevated by a periosteal elevator)

Small skin incisions were made at the palmar surface of the second phalanx of the third and fourth digits of the right forelimb, allowing for selective tenectomy of the tendon branches of the deep digital flexor muscle (DDFM) of these digits (Figure 4).

Twelve hours postoperatively, a certain degree of hyperflexion of the carpal joints and a moderate bilateral forelimb lameness persisted (Figure 5).
