Segmented Double-Unit Bridging Technique Using Autologous Semitendinosus Graft for Massive Irreparable Rotator Cuff...

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Massive irreparable rotator cuff tears, particularly involving the supraspinatus, present a significant surgical challenge.
• Existing treatments like superior capsular reconstruction offer limited, static solutions, failing to restore dynamic shoulder function.

Purpose of the Study:

• To describe a novel segmented double-unit bridging technique for anatomical and dynamic reconstruction of massive irreparable rotator cuff tears.
• To present a simplified and stable surgical approach for restoring shoulder biomechanics.

Main Methods:

• A segmented double-unit bridging technique using autologous semitendinosus tendon was developed.
• The tendon was divided into two independent segments, each folded into a graft unit.
• These units were sequentially implanted to bridge the anterior and posterior portions of the supraspinatus defect.

Main Results:

• The technique simplifies graft handling and suture management compared to single-graft methods.
• It enables a stable and anatomical repair, addressing the irreparable supraspinatus defect.
• The method facilitates dynamic reconstruction, restoring shoulder biomechanics.

Conclusions:

• The segmented double-unit bridging technique offers a practical surgical solution for massive irreparable rotator cuff tears.
• This approach provides anatomical and dynamic reconstruction, improving upon current static methods.
• It represents a viable option for surgeons managing complex rotator cuff defects.
