Tani et al: Reconstruction of the flexor carpi ulnaris tendon with a fascia lata autograft in two dogs with carpal hyperextension
Veterinary Surgery 8, 2022

🔍 Key Findings

  • Fascia lata autograft reconstruction of the FCU tendon successfully treated carpal hyperextension in both dogs.
  • Primary repair was not possible in one dog due to complete rupture; a fascia lata graft bridged the tendon gap.
  • In the second case, elongated tendon was corrected and reinforced with fascia lata to prevent recurrence.
  • Type I external skeletal fixation was used for 6 weeks to support tendon healing in both dogs.
  • Postoperative gait and range of motion returned to normal, with no recurrence at 36-month follow-up.
  • Ultrasonography aided diagnosis, revealing thinning and echogenic changes in the FCU tendon.
  • Histologic findings showed mild, nonspecific muscle changes, suggesting injury rather than a systemic disease.
  • No complications occurred, and fascia lata showed potential for biological integration and remodeling into tendon-like structure.

Multiple Choice Questions on this study

In Tani 2022 et al., on FCU tendon reconstruction, what type of fixation was used postoperatively to protect the repair?

A. Type II external fixator
B. Type Ia external fixator
C. Type I external skeletal fixator
D. Padded bandage only
E. Cast and splint

Answer: Type I external skeletal fixator

Explanation: Type I ESF was used to immobilize the radius and metacarpals for 6 weeks to protect the repair.
In Tani 2022 et al., on FCU tendon reconstruction, what diagnostic modality helped identify FCU involvement preoperatively?

A. CT scan
B. Fluoroscopy
C. Ultrasonography
D. MRI
E. Arthrography

Answer: Ultrasonography

Explanation: Ultrasonography revealed a thinner FCU tendon and echogenic changes in the affected limb, aiding diagnosis.
In Tani 2022 et al., on FCU tendon reconstruction, what did histology of the FCU in Case 1 reveal?

A. Pyogranulomatous inflammation
B. Marked fibrosis and ossification
C. Purulent tenosynovitis
D. Mild nonspecific degeneration
E. No abnormalities

Answer: Mild nonspecific degeneration

Explanation: Histology showed mild atrophy and degeneration, consistent with injury rather than systemic disease.
In Tani 2022 et al., on FCU tendon reconstruction, what was the main reason for using a fascia lata autograft in Case 1?

A. To enhance strength of the primary repair
B. To avoid donor site morbidity
C. To bridge a complete tendon rupture
D. To improve cosmetic outcome
E. To prevent immune rejection

Answer: To bridge a complete tendon rupture

Explanation: Primary repair was not possible due to a 24 mm tendon gap; fascia lata was used as a bridging graft.
In Tani 2022 et al., on FCU tendon reconstruction, what was the long-term outcome for both dogs?

A. Development of degenerative joint disease
B. Recurrence of hyperextension
C. Improved flexion but reduced extension
D. Normal gait and joint motion
E. Requirement for arthrodesis later

Answer: Normal gait and joint motion

Explanation: At 36-month follow-up, both dogs had full function with no recurrence of hyperextension.
