Coracoid transfer in Bristow–Latarjet procedure: does it modify the biceps muscle?

The aim of this study is to evaluate the size and morphologic patterns of the biceps muscle after coracoid transfer performed during the Bristow–Latarjet procedure to treat anterior shoulder instability. We analyzed retrospectively 26 patients, who underwent a Bristow–Latarjet procedure, and 23 volunteers (control group) with no shoulder disease. A US machine (ATL 5000 HDI, probe 4.2 MHz) was used to determine the biceps section area (BA) and biceps echogenicity (BE). The dominant and non-dominant limbs in both groups were compared. The coracoid transfer performed in the Bristow–Latarjet procedure to treat recurrent anterior shoulder instability does not modify the size and morphology of the biceps muscle.
