Schuenemann et al: Biceps tenodesis with a bioabsorbable bone anchor using BoneWelding technology: Results in six clinical cases (5 dogs)
Veterinary Surgery 4, 2025

🔍 Key Findings

  • Case series of 6 shoulders in 5 working/sporting dogs. Conditions treated: 3 partial biceps ruptures, 3 luxations with fraying.
  • All treated with biceps tenodesis using a bioabsorbable anchor (Weldix 2.3 mm).
  • All dogs returned to function (some to high-level sports); lameness resolved within 1–5 weeks.
  • No implant-related complications with anchor-only cases. One dog had seroma and later infection but recovered.
  • Tendon clamp (used in 2 cases) caused irritation in one dog → resolved after removal.
  • CT follow-up confirmed integrity; drill holes filled with bone.
  • Median LOAD score: 12; higher in older dogs or with concurrent conditions.
  • Authors suggest tenodesis offers more stability and faster return to function than tenotomy in working dogs.
  • Larger, controlled studies are recommended.

Multiple Choice Questions on this study

In Schuenemann 2025 et al., on biceps tenodesis, what was a key CT finding during follow-up?

A. Hole enlargement around anchor
B. Periosteal reaction at fixation site
C. Drill hole filled with new bone
D. Anchor migration to joint space
E. Cyst formation near implant

Answer: Drill hole filled with new bone

Explanation: CT follow-up showed progressive bone fill at the anchor site with no signs of lysis or failure.
In Schuenemann 2025 et al., on biceps tenodesis, what was the anchor type used in all cases?

A. Metallic screw anchor
B. Bone tunnel suture anchor
C. Titanium suture button
D. Bioabsorbable BoneWelding anchor
E. Nonabsorbable toggle pin

Answer: Bioabsorbable BoneWelding anchor

Explanation: A 2.3 mm bioabsorbable Weldix anchor using BoneWelding technology was used in all tenodesis cases.
In Schuenemann 2025 et al., on biceps tenodesis, which complication occurred with the use of the tendon clamp?

A. Implant loosening
B. Recurrent luxation
C. Seroma and abscess
D. Tendon re-tear
E. Screw migration

Answer: Seroma and abscess

Explanation: The one case using a tendon clamp developed seroma and later abscess, resolving after treatment.
In Schuenemann 2025 et al., on biceps tenodesis, what was the functional outcome in all dogs?

A. Returned to partial weight bearing
B. Required revision surgery
C. Lameness resolved within 6–12 weeks
D. Returned to full function
E. Limited ROM persisted

Answer: Returned to full function

Explanation: All dogs returned to full function, including high-performance sports in some cases.
In Schuenemann 2025 et al., on biceps tenodesis, what LOAD score pattern was observed in the cohort?

A. High scores in all cases
B. Median score < 5 in young dogs
C. Median score 25 across all cases
D. Median score 12, higher in older dogs
E. Consistent score of 10 across cases

Answer: Median score 12, higher in older dogs

Explanation: Median LOAD score was 12; older dogs and those with comorbidities had higher scores.
