Traumatic distal biceps brachii tendon injuries
Distal biceps brachii tendon (DBBT) injuries occur mainly in men aged 40–60 years. Traumatic DBBT injuries have been classified by De la Fuente et al. (2017).
1. Major injuries: those that require surgical management.
a) Complete tear: complete loss of DBBT attachment to the radial tuberosity;
- Bicipital aponeurosis intact: direct visual confirmation of intact external bicipital aponeurosis (EBA) or a retraction gap less than or equal to 8 cm;
- Bicipital aponeurosis torn: direct visual confirmation of torn EBA or a retraction gap of more than 8 cm.
b) High-grade partial tear: tendon disruption affecting more than 50% of the DBBT attachment .
2. Minor injuries: those that do not require surgical management.
a) Low-grade partial tear: tendon disruption affecting less than or equal to 50% of the DBBT attachment;
b) Elongation injuries or tendinopathies: altered tendon pattern without signs of tearing.
