[Traumatic rupture of the triceps brachii tendon and ipsilateral Achilles tendon]

We report on a 71-year-old male farmer who sustained an injury to the tendons of the triceps brachii and the Achilles tendon on the left side. The diagnosis was based on clinical investigations and ultrasound. The triceps brachii tendon was repaired with open transosseous sutures. Six weeks after the operation we only allowed passive mobilization. The Achilles tendon rupture was treated with a semi-open procedure. Four weeks after the operation the ankle was fixed in 30 degrees plantar flexion, followed by 2 weeks in neutral position. Full weight bearing was allowed. Six months after the operation the patient no longer had any problems with his injury. Injuries of the tendon of the triceps brachii are very rare, with an incidence of 0.8%. We could not find case reports of a simultaneous injury to another tendon in the literature.
