Case series summary Three cats, Siamese or Siamese cross, were presented with a chronic thoracic limb weightbearing lameness. Previous anti-inflammatory administrations were unable to improve lameness consistently in the three cats. Two of the three cats had undergone onychectomy several years before presentation. A permanent flexion of the proximal interphalangeal joint of one or more digits, associated with a difficult and painful extension of the proximal interphalangeal joint, was noticed during orthopedic examination. A digital flexor tendon contracture was suspected and confirmed with radiographic examination. Surgical exploration was then performed. For all cats, treatment consisted of a tenectomy or tenotomy of the superficial and deep digital flexor tendons in order to release the contracture. The three cats responded well to the surgical treatment and became sound around 2–4 weeks after surgery. Relevance and novel information Digital flexor tendon contracture is rarely reported as a cause of lameness in cats. It should be considered in a differential diagnosis of feline lameness whenever onychectomy has been performed in the past. The precise etiology that explains this tendon contracture is unknown, but trauma or breed predisposition could represent potential causes.
