Late Distal Biceps Tendon Reconstruction Using Lacertus Fibrosus Transfer and Suture Anchor Fixation

Methods of delayed distal biceps tendon repair range from direct repair to tendon reconstruction using autografts or allografts. A 33-year-old man underwent, under our care, a right dominant arm, distal biceps tendon exploration and reconstruction 10 months after injury. During the procedure, the lacertus fibrosus was found intact, hypertrophied, and attached proximally to the short head of biceps and was decided to be used as a local autograft for the tendon repair. The lacertus was carefully dissected from the ulna distally and preserving its vascularity, the proximal stump was sutured to both long and short heads of the biceps muscle. The lacertus fibrosus mass was then tubularized and secured distally onto the radial tuberosity using anchor fixation. At his 6-month follow-up postoperatively, the patient had achieved normal elbow function and strength. The presented technique can be a viable option when the lacertus fibrosus is found intact, avoiding the complications of complex distal biceps reconstructive autograft or allograft procedures.
