Simultaneous bilateral distal biceps tendon ruptures repaired using an endobutton technique: a case report.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Traumatology

Background:

• Simultaneous bilateral distal biceps tendon ruptures are exceptionally rare and pose significant treatment challenges.
• Existing literature lacks established protocols for managing acute bilateral distal biceps tendon ruptures.
• The single anterior incision with cortical suspensory button technique is gaining popularity for distal biceps tendon repair.

Purpose of the Study:

• To present a surgical approach for acute simultaneous bilateral distal biceps tendon ruptures.
• To describe an endobutton technique and rehabilitation algorithm for this specific injury pattern.
• To evaluate the outcomes of this treatment strategy in a clinical case.

Main Methods:

• A case report of a 43-year-old male with acute bilateral distal biceps tendon ruptures.
• Surgical repair utilizing a single anterior incision with endobutton fixation for both tendons.
• A staged repair approach, addressing the right side first, followed by the left side six weeks later.
• Implementation of a specific rehabilitation protocol post-surgery.

Main Results:

• The patient achieved good functional recovery, returning to full manual work at 30 months post-surgery.
• The patient reported 85% of his premorbid functional level.
• Mild lateral antebrachial cutaneous nerve dysesthesias were noted on the right side post-operatively.

Conclusions:

• This case represents, to our knowledge, the first successful treatment of simultaneous bilateral distal biceps tendon ruptures using a single-incision endobutton technique.
• The described surgical approach and rehabilitation algorithm are effective for managing this unusual injury.
• This technique offers a valid and successful option for patients with acute bilateral distal biceps tendon ruptures.
