Mini-Open Biceps Tenodesis Using an Onlay Technique With Enthesis Growth Augment

Area of Science:

• Orthopedic Surgery
• Regenerative Medicine
• Biomaterials Science

Background:

• Acute ruptures of the long head of the biceps tendon cause significant anterior shoulder pain and weakness.
• Current onlay tenodesis techniques show comparable outcomes to traditional methods but can be limited by enthesis healing failures.
• Optimizing tendon-to-bone healing is crucial for reducing complication rates in biceps tenodesis.

Purpose of the Study:

• To describe a novel, biologically augmented onlay biceps tenodesis technique.
• To evaluate the potential of demineralized bone matrix implants to enhance enthesis regeneration and healing.
• To offer a reproducible alternative for proximal biceps tenodesis with improved healing outcomes.

Main Methods:

• A biologically augmented onlay biceps tenodesis procedure was developed.
• A demineralized bone matrix enthesis implant (EnFix) was utilized to promote tendon-to-bone healing.
• The technique focuses on enhancing enthesis regeneration through osteoconductive and osteoinductive properties.

Main Results:

• The demineralized bone matrix implant facilitates enhanced tendon-to-bone healing.
• This biologically augmented approach promotes enthesis regeneration.
• The technique is presented as a reproducible method for proximal biceps tenodesis.

Conclusions:

• Biologically augmented onlay biceps tenodesis using demineralized bone matrix offers a promising alternative.
• This method may optimize enthesis healing and reduce the risk of failure in proximal biceps tenodesis.
• Enhanced tendon-to-bone healing through regenerative strategies is key to improving surgical outcomes.
