Combined rupture of the tibialis anterior and the extensor hallucis longus tendons--functional reconstruction.

Background: Traumatic rupture of the tibialis anterior (TA) tendon represents a very rare foot injury. A combined injury of both the TA and the extensor hallucis longus (EHL) tendons has not yet been reported. Within the scope of this work we will prove that tendon transfers in cases of combined tendon injuries are a reasonable course of action in order to achieve the aim of a functional reconstruction.

Treatment of posterior epiphyseal disruption of the medial clavicle with a modified Balser plate.

Background: Acute posterior dislocation of the sternoclavicular joint is a rare but dangerous injury that is often difficult to diagnose. Because of late closure of the medial clavicular epiphysis, epiphyseal disruption must be taken into consideration in patients up to 25 years of age with an apparent diagnosis of posterior sternoclavicular dislocation. We developed a novel method of treating epiphyseal disruptions with a modified Balser plate.

Expandable nail system for osteoporotic humeral shaft fractures: preliminary results.

Background: Conventional nails rely on interlocking screws for axial and rotational stability. Such screws have poor fixation in patients with poor bone quality (osteopenia). The Fixion nail does not depend on interlocking screws-axial and rotational stability is instead achieved by nail expansion.
