No effect in a prospective randomized study. The repair of a fracture of the styloid process of the ulna is not necessary if reduction and fixation of the distal radius fracture is anatomical and stable.Īf Ekenstam F, Jakobsson OP, Wadin K (1989) Repair of the triangular ligament in Colles‘ fracture. Neither the existence nor the location of the fracture of the styloid process of the ulna had a significant effect on the radiological and functional results (p function=0,849, p radiology=0,330, p scores=0,426, MANOVA). Three groups (patients without a fracture of the styloid process of the ulna, patients with a tip fracture and those with a basal fracture) were evaluated by multivariate analysis (MANOVA) in order to detect influences of the fracture of the styloid process of the ulna on the radiological and functional results. The fracture of the styloid process of the ulna was not repaired. Out of 480 patients with operatively treated distal radius fractures 238 were examined at least 1 year after injury. This study evaluated radiological and functional results after different operative treatment procedures of distal radius fractures in patients with an untreated fracture of the styloid process of the ulna and those without such a fracture. There are well-defined criteria for the treatment of distal radius fractures but the impact of an unrepaired fracture of the styloid process of the ulnar on recovery after operative treatment is uncertain. Schlussfolgerungīei anatomischer Reposition und adäquater Refixation der distalen Radiusfraktur erscheint eine operative Versorgung von Spitzenabrissen als auch basisnaher Frakturen des Processus styloideus ulnae nicht notwendig. Weder das Vorhandensein noch die Lokalisation eines Abrisses des Processus styloideus ulnae hatten einen signifikanten Einfluss auf die funktionellen und radiologischen Ergebnisse (p funktionell=0,849, p radiologisch=0,330, p Scores=0,426, MANOVA). Durch eine multivariate Analyse (MANOVA) wurde ermittelt, ob ein basisnaher oder peripherer Styloidabriss das radiologische oder funktionelle Ergebnis beeinflusst. Die funktionellen und radiologischen Ergebnisse wurden gemessen. Die Patienten wurden in 3 Gruppen unterteilt: ohne Ulnastyloidfraktur, mit Spitzen- und mit Basisabriss. Eine Versorgung des Ulnastyloids fand in diesem Zeitraum nicht statt. Mindestens ein Jahr postoperativ wurden 238 von 480 Patienten mit operativ versorgter distaler Radiusfraktur nachuntersucht. Gegenstand der vorliegenden Studie war die Frage der Behandlungsbedürftigkeit dieser Verletzung. Über die Notwendigkeit einer operativen Versorgung der häufigen Begleitfraktur des Processus styloideus ulnae herrscht jedoch noch Uneinigkeit. pathological fracture e.g.Kriterien zur Indikation und Art der Versorgung einer distalen Radiusfraktur sind etabliert. ![]() persistent ulnar styloid or other accessory ossicles of the wrist that occur around the distal ulna. ![]() It is argued that these injuries, therefore, need open stabilization. It is believed that lack of union of these avulsion fractures does not significantly affect late functional results. Fractures at the very base of the ulnar styloid can cause instability of the distal radioulnar joint (DRUJ) and disruption of the triangular fibrocartilage complex (TFCC) insertion at the ulnar fovea. In the pediatric and adolescent forearm, it should be remembered that in very rare situations the ulnar styloid can arise from a separate ossification center, but mostly separation is caused by injury. Sometimes the fractures may not seem very apparent on x-ray if there is no displacement. The fracture is easy to recognize on plain film. Usually, this kind of fracture occurs as the result of a fall on an outstretched arm and is often associated with a distal radius fracture.
