Outcome of Surgical Repair of Complete Rupture of Distal Biceps Tendon: A Clinical Series by GM Yathisha Kumar in BJSTR
Abstract
Complete distal biceps rupture is a rare injury as compared to
proximal biceps tendon rupture. It is usually caused by an eccentric
contraction of the muscle, often seen with a sudden unintentional pull
or jerk. An epidemiological study showed an incidence of 1.2 ruptures
per 100,000 patients per year with an average age of 47 years. It is
important not to miss the diagnosis initially, since delay in surgery
does
affect the outcome. In low-demand patients with complete distal biceps
tendon tears, non-operative treatment may be entertained provided
the patient understands the potential for residual weakness,
particularly of forearm supination. The surgical repair is the treatment
of choice
especially in high demand male patients. There are a variety of fixation
methods including bone anchors, suspension techniques, bone tunnels
with interference screws, and transosseus sutures. No one technique has
emerged as the gold standard and the choice remains that of surgeon.
In this case series we present couple of patients with distal biceps
tendon rupture one with acute rupture and another with chronic rupture
treated surgically. We conclude patients do benefit from surgical
repair.
