Introduction: The dimensions of currently available bone anchors preclude their use in many indications particularly in small dogs and cats in distal limb regions.

Materials and Methods: WELDIX anchors based on the BoneWelding technology were used in 9 clinical cases (6 cats and 3 dogs) for ligament reconstruction, reinsertion, and tendon reinsertion. Variable suture materials were used including Maxon, Prolene, and Ethibond.

Results: Indications were tarsocrural luxation or tarsal ligament reconstruction in 4 cases, coxofemoral luxation in 3 cases, Achilles tendon disruption and elbow medial collateral ligament reinsertion in one case each. There was one major (coxofemoral reluxation requiring FHO) and two minor complications (skin dehiscence and local swelling around the calcaneus), which both healed with conservative treatment. Outcomes were excellent in six cases (full function) and good (slight lameness) in two.

Discussion/Conclusion: The WELDIX anchor is a promising technology offering advantages over other anchor systems in specific indications. Its small size and flush insertion enable application in locations previously inaccessible with anchors, such as the insertion point of the tibiotalar ligament under the medial malleolus. Further clinical investigation of this system is warranted.
