Treatment of a Complex Distal Triceps Tendon Rupture With a New Technique: A Case Report.

INTRODUCTION: The distal triceps tendon rupture is an uncommon injury. The acute treatment is well-defined, but when a delayed diagnosis is made or when a tendon retraction is present the alternatives or reconstruction are limited and sometimes complex. CASE PRESENTATION: In this case, we report on a 28-year-old man who presented with a chronic disruption of the distal triceps tendon with a gap of approximately 15 cm. The patient was diagnosed in another center with an inveterate breakage of the distal triceps tendon and was initially treated with an Achilles allograft that was complicated by a wound infection and required more than ten surgeries. Nearly 22 months after the initial trauma, and 12 months after the first surgery, we performed a reconstruction with an Achilles tendon allograft using the new technique of distal attachment. At the 12-month follow-up the patient presented a joint balance from -5º to 110º and presented with no pain. CONCLUSIONS: The use of an Achilles tendon allograft provides excellent results in complex distal triceps tendon ruptures. We report the use of a new technique to anchor a distal Achilles allograft.

Unusual pattern of Essex-Lopresti injury with negative plain radiographs of the wrist: a case report and literature review.

The Essex-Lopresti injury consists of a fracture of the radial head, rupture of the interosseous membrane and disruption of the distal radioulnar joint. The greatest challenge with this injury pattern is the diagnosis, because it is frequently missed and the attention usually focused on the elbow joint. In this paper we report an unusual pattern of Essex-Lopresti injury with a radial neck fracture, a tear of the interosseous membrane and a disruption of the distal radioulnar joint in which initial wrist radiographs did not show significative abnormalities. Open reduction and internal fixation for the radial head fracture was performed. Forearm rotation was locked with two Kirschner wires from ulna to radius to allow interosseous membrane to heal. This case is even more difficult to diagnose than classic Essex-Lopresti pattern because of the absence of radius shortening, due to this specific radius fracture pattern, and also the absence of distal radioulnar joint dislocation. When treating a radial head fracture but also a radial neck fracture, interosseous membrane injury should be suspected to avoid misleading in diagnosis.
