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

BACKGROUND: There are many techniques described to repair acute distal biceps tendon ruptures. The authors' objective is to report the results of a single-incision technique using a combination of a soft tissue button and biotenodesis interference screw with accelerated rehabilitation.

HYPOTHESIS: Dual fixation of a distal biceps rupture will allow for early return to function.

STUDY DESIGN: Case series; Level of evidence, 4.

METHODS: From February 2004 to July 2007, 41 elbows in 40 patients had repair of an acute distal biceps tendon rupture (<6 weeks) through an anterior incision using a soft tissue button and interference screw combined technique. The patients were evaluated pre- and postoperatively with a physical examination, radiographs, and the Andrews-Carson elbow score. Nine patients were unavailable for follow-up. The remaining 31 patients (32 elbows) were contacted for a telephone interview at an average of 24 months postoperatively.

RESULTS: The preoperative Andrews-Carson score averaged 168 and the postoperative Andrews-Carson score averaged 196 points at final clinical follow-up. There was a statistically significant difference between the pre- and postoperative Andrews-Carson scores (P < .001). One patient had heterotopic ossification associated with decreased pronation and supination. Two superficial radial nerve palsies completely resolved by final follow-up. The average postoperative time to resume normal activities or return to work was 6.5 weeks.

CONCLUSION: Repair of acute distal biceps tendon ruptures using a soft tissue button and interference screw technique through a limited anterior incision can allow for accelerated rehabilitation and early return to function.
