Isolierte Korpusquerfraktur des Os triquetrum Fallbeschreibung einer seltenen Verletzung

Abstract

With the case of a 25 year old patient we will report of a rare injury, the isolated body fracture of a triquetrum bone. This kind of injury often happens in dorsalflected and ulnarducted hand position because of the anatomical position of the triquetral bone. The therapy of choice is conservative treatment with a volar splint for three to six weeks. Operation is only necessary in case of dislocation of a fragment [4]. Complications as an aseptic necrosis of a fragment is not reported. We found only one case of a pseudarthrosis [5]. Even in our case occurred a complete healing of the bone and a complete functional remission.

Isolated Triquetrum Fractures: The Importance of Proper Roentgenograms in Ulnar Sided Wrist Pain

“…Independently of the type of fracture, as it is in our series, correct diagnosis of triquetrum fractures that can be successfully treated with conservative treatment including immobilization for 4 -6 weeks as a rule is also the mainstay for the treatment process [5] [7] [8]. Obtaining also oblique wrist radiographs in addition to anteriorposterior and lateral wrist radiographs is important, because dorsal chip fractures undetermined on lateral radiographs have been reported on oblique radiographs [6] [9].…”
