Repair of distal biceps brachii tendon ruptures:
long term retrospective follow-up for two-incision technique
Introduction: Rupture of the distal tendon of the biceps
muscle is a rare injury. If unrepaired the patient will be left
with weakness of supination of the arm and flexion in the
elbow. Long term results for the 2-incision approach for
tendon reinsertion are few but in this study we describe
the long term, clinical, functional, and subjective results of
surgical repair using the 2-incision method described by
Boyd and Anderson.
Material and methods: All patients who were operated
at FSA hospital during the years 1986-2000 because of
rupture of the distal tendon of the biceps muscle were
asked to participate in the study. Twelve of 16 patients
accepted and answered the DASH questionnaire. Strength
was tested with handheld dynamometer and ROM where
measured. Radiograph was taken of the affected arm.
Results: From 1986 through 2006 we operated on 16
patients because of rupture of the distal biceps tendon,
one female and 15 male. Mean age at the time of rupture
was 46 years (24-53).The average follow up were seven
years (1-17). Ten of 12 patients were operated within two
weeks from the injuries. No difference in strength was
found between operated and non-operated arms. Late
repair was associated with high DASH score and poor
subjective results. Six patients developed heterotopic
ossification but none of them developed radioulnar
synostosis. One reoperation because entrapment of the
median nerve was done.
Conclusions: Despite heterotopic ossification and a small
ROM deficit the Boyd and Anderson technique for repair
of distal biceps ruptures yields good long term results in
a iow volume rural hospital. Early diagnosis and tendon
reinsertion is of great importance to avoid persistent
anterior elbow pain and poor subjective results.
