Lacerations of the flexor hallucis longus in the young athlete
JP Frenette and DW Jackson
Of ten patients with lacerations of the flexor hallucis longus tendon, nine
were athletically inclined. In four, the laceration was not repaired and no
disability was evident. A functioning flexor hallucis longus, therefore,
does not seem to be essential for good push-off and balance in running
sports. If both the flexor hallucis brevis and the flexor hallucis longus
are lacerated and reconstitution of the longus is not possible, the brevis
should be repaired, suturing the distal segment of the longus to brevis to
prevent hyperextension deformity of the metatarsophalangeal joint.
Hypersensitivity of the scar due to associated nerve injury is a frequent
complication associated with laceration of the flexor hallucis longus.
