A combined technique for distal biceps repair using a soft tissue button and biotenodesis interference screw

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Tendon Repair

Background:

• Acute distal biceps tendon ruptures have various repair techniques.
• This study evaluates a specific single-incision technique.

Purpose of the Study:

• To report the outcomes of a single-incision distal biceps tendon rupture repair.
• To assess the efficacy of dual fixation with a soft tissue button and biotenodesis interference screw.
• To evaluate the potential for accelerated rehabilitation and early return to function.

Main Methods:

• A case series (Level of evidence, 4) of 41 elbows in 40 patients with acute distal biceps tendon ruptures (<6 weeks).
• Repair was performed via a single anterior incision using a soft tissue button and interference screw.
• Patients were evaluated pre- and postoperatively using physical examination, radiographs, and the Andrews-Carson elbow score.

Main Results:

• Postoperative Andrews-Carson scores showed a statistically significant improvement (average 196 vs. 168, P < .001).
• The average time to resume normal activities or return to work was 6.5 weeks.
• One case of heterotopic ossification and two cases of superficial radial nerve palsy (fully resolved) were noted.

Conclusions:

• A single-incision technique combining a soft tissue button and interference screw is effective for acute distal biceps tendon rupture repair.
• This method facilitates accelerated rehabilitation and an early return to function.
• The dual fixation approach provides a stable repair allowing for prompt patient recovery.
