Bilateral Distal Myotendinous Biceps Ruptures: A Case Report

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Musculoskeletal Research

Background:

• Distal biceps tendon ruptures are uncommon, with most occurring as avulsions from the radial tuberosity.
• This case involves bilateral ruptures at the distal myotendinous junction, a rare injury pattern.
• The patient experienced two separate rupture incidents 15 months apart.

Purpose of the Study:

• To report a rare case of bilateral distal biceps tendon ruptures at the myotendinous junction.
• To highlight the diagnostic challenges and management of this uncommon injury pattern.
• To emphasize the importance of clinical evaluation and rehabilitation for functional recovery.

Main Methods:

• A case report of a 41-year-old male patient with bilateral distal biceps tendon ruptures.
• Diagnosis aided by physical examination due to inconclusive initial imaging.
• Surgical intervention involving open repair of the right distal biceps tendon.

Main Results:

• The patient presented with bilateral distal biceps tendon ruptures at the myotendinous junction.
• Initial imaging was inconclusive, necessitating a thorough physical examination for diagnosis.
• Open repair of the right side was performed due to persistent weakness in elbow flexion and supination.

Conclusions:

• This case highlights an unusual location for distal biceps rupture.
• Emphasizes the critical role of careful clinical assessment in diagnosing such injuries.
• Underscores the significance of surgical decision-making and tailored rehabilitation for optimal outcomes.
