An isolated 1B-lesion of the TFCC is rather unusual.ĭiscus ulnocarpalis - ulnocarpal complex - triangular fibrocartilage complex - traumatic 1B-lesion - arthroscopic refixation - wrist Literatur Results: The Mayo modified wrist score was preoperatively 49.74☒0.99 and postoperatively 82.43☑5.89 (p0.05).Ĭonclusion: The results of the current study suggest that 1B-lesions of the TFCC can be successfully repaired by arthroscopically assisted suture techniques. The Mayo modified wrist score and the disability of arm, shoulder and hand (DASH) score were used to identify the outcome. Patients with revision operations or neurovascular pathology were excluded. On average, the follow-up examination was performed after 7.9 years (range: 3.2–14.3) years. In 16 cases, we operated the left and in 20 cases the right TFCC. The average age of the 18 male and 18 female patients was 43.8 (range: 22–70) years. Methods: Thirty-six patients who underwent an arthroscopic repair of traumatic 1B-lesions of the TFCC without a dislocation of the ulnar styloid process were included in this study. AbstractĪim: The aim of the study was to investigate the postoperative outcome of the arthroscopic sutures of traumatic 1B-lesions of triangular fibrocartilage complex (TFCC) tears. Isolierte 1B-Läsionen des Discus ulnocarpalis sind selten. Schlussfolgerung: Diese Studie zeigt, dass die arthroskopische Naht von 1B-Läsionen des Discus ulnocarpalis zufriedendstellende Ergebnisse bringt. Ausgeschlossen wurden Patienten mit Revisionsoperationen und neurovaskulären Erkrankungen.Įrgebnisse: Der Mayo Modified Wrist Score ergab präoperativ 49,74☒0,99 und postoperativ 83,13☑5,89 Punkte (p0,05). Der Zeitpunkt der Nachuntersuchung betrug im Durchschnitt 7,34 Jahre (3,2–14,3). In 16 Fällen war die linke, in 20 Fällen die rechte Hand betroffen. Die Patienten waren durchschnittlich 43,8 Jahre alt (22–70), davon 18 männliche und 18 weibliche Patienten. Methode: Arthroskopische Refixation von traumatischen 1B-Läsionen des Discus ulnocarpalis ohne Abriss des Processus styloideus ulnae, welche arthroskopisch refixiert wurden. Ziel: Studienziel waren die mittelfristigen postoperativen Ergebnisse von arthroskopischen Nähten traumatischer Diskusläsionen vom Typ 1B- nach Palmer.

This article incorporates text in the public domain from page 218 of the 20th edition of Gray's Anatomy (1918) This is important in preventing pressure ischaemia. The position of the styloid process of the ulna in relation to the wrist must be considered when applying a wrist splint. Conservative management involves injection of triamcinolone, while surgery involves shortening of the styloid process of the ulna via resection. When the DRUJ is unstable, the ulnar styloid may require independent treatment.Īn excessively long styloid process of the ulna can cause painful contact with the triquetral bone in the wrist, known as ulnar styloid impaction syndrome. The major exception is when the joint between these bones, the distal radioulnar joint (or DRUJ), is unstable. Clinical significance įractures of the styloid process of the ulna seldom require treatment when they occur in association with a distal radius fracture. The radioulnar ligaments also attaches to the base of the styloid process of the ulna. The rounded end of the styloid process of the ulna connects to the ulnar collateral ligament of the wrist. The styloid process of the ulnar varies in length between 2 mm and 6 mm. The head is separated from the styloid process by a depression for the attachment of the apex of the triangular articular disk, and behind, by a shallow groove for the tendon of the extensor carpi ulnaris muscle. It descends a little lower than the head. The styloid process of the ulna projects from the medial and back part of the ulna. The styloid process of the ulna is a bony prominence found at distal end of the ulna in the forearm.
