Distal biceps tendon reconstruction in chronic ruptures.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Reconstructive Surgery

Background:

• Chronic distal biceps tendon ruptures often require surgical intervention.
• Nonanatomic reattachment to the brachialis muscle is a common but potentially suboptimal treatment.
• Anatomic repair aims to restore native function and biomechanics.

Purpose of the Study:

• To evaluate the outcomes of anatomic distal biceps tendon reconstruction using an Achilles tendon allograft.
• To assess functional recovery, strength, and patient satisfaction after this procedure.

Main Methods:

• Retrospective study of 7 male patients with chronic distal biceps ruptures.
• Anatomic reattachment via a single anterior incision using suture anchors and an Achilles tendon allograft.
• Follow-up averaged 29 months, assessing range of motion, strength, and Mayo Elbow Performance Score.

Main Results:

• Mean elbow flexion of 145 degrees and mean pronosupination of 170 degrees achieved.
• All patients demonstrated 5/5 strength in flexion and supination and returned to employment.
• Mean supination strength was 87% of the contralateral side; 7/7 patients had good or excellent Mayo scores.
• No complications were reported.

Conclusions:

• Anatomic distal biceps tendon reconstruction with an Achilles tendon allograft is a safe and effective option.
• This technique offers excellent functional restoration for patients with high demands, particularly in pronosupination.
• It serves as a superior alternative to nonanatomic repairs for chronic ruptures.
