The real question is whether it was a rupture of the long head of the biceps(shoulder) or the distal biceps tendon(elbow).
A rupture of the long head occurs frequently and leads to a "Popeye Deformity" but if untreated presents a cosmetic problem but not much of a functional issue for the average person. In an elite athlete a tenodesis to the proximal humerus will probably be done. Biceps tenodesis is done commonly in shoulder labral damage. In Europe the tendon is usually released since it is simpler and reduces stress risers that occur at the tenodesis site that can lead to delayed fracture.
A rupture of the distal biceps tendon must be repaired. Traditionally, it was done with 2 incisions but now is often repaired with a single anterior incision. I still preferred the 2 incision technique because nerve damage was less likely.
I rendered a second opinion to a patient with a ruptured distal biceps and recommended a 2 incision repair. He essentially called me crazy. He had a single incision repair and suffered a nerve injury that lead to severe disability in his dominant arm. This is the reason , I prefer the 2 incision technique. Old school techniques sometimes are still better than new techniques
