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, weakness, and deformity.
• Onlay tenodesis techniques using anchors or buttons offer clinical outcomes similar to traditional inlay methods.
• Complications in onlay tenodesis are often linked to inadequate enthesis healing.

Purpose of the Study:

• To describe a novel, biologically augmented onlay biceps tenodesis technique.
• To evaluate the use of a demineralized bone matrix implant for enhancing tendon-to-bone healing.
• To present a reproducible method for proximal biceps tenodesis with improved healing potential.

Main Methods:

• A biologically augmented onlay biceps tenodesis was performed using a demineralized bone matrix enthesis implant (EnFix).
• The implant's osteoconductive and osteoinductive properties were utilized to promote enthesis regeneration.
• The technique focuses on enhancing tendon-to-bone healing at the fixation site.

Main Results:

• The demineralized bone matrix implant facilitates enhanced tendon-to-bone healing.
• The technique shows potential for promoting enthesis regeneration.
• This method offers a biologically enhanced approach to proximal biceps tenodesis.

Conclusions:

• Biologically augmented onlay biceps tenodesis using demineralized bone matrix is a viable alternative.
• This technique may optimize enthesis healing and decrease the incidence of construct failure.
• Further clinical evaluation is warranted to confirm long-term outcomes.
