Surgical treatment of a bilateral superficial flexor tendon luxation

Abstract

A two-year-old, male, neutered, crossbreed dog was presented to Anderson Moores Veterinary Specialists with a history of bilateral pelvic limb lameness. Right pelvic limb lameness was first noted 3 months prior to presentation. Right superficial digital flexor tendon tendinopathy and associated bursitis were diagnosed based on computed tomography scans performed by the referring veterinarian. Conservative management, consisting of analgesia and exercise restriction, did not resolve the clinical signs and referral was sought. At the time of presentation, left pelvic limb lameness of 1 week's duration was reported additionally by the owner. Clinical examination and imaging findings were consistent with bilateral superficial digital flexor tendon luxation. Surgical management consisting of relocation of the superficial digital flexor tendon into the central position of the calcaneal groove alongside a retinaculoplasty and calcaneoplasty was performed bilaterally. Half-cast dressings were placed on both pelvic limbs and were removed after 3 weeks due to mild soft tissue complications. The patient was cage rested for 5 weeks in total. The re-examination 8 weeks after surgical treatment revealed that the tendons remained stable and could not be manually luxated.
