The extent of resection should be planned individually, and sometimes an oblique resection may be the preferred option. Clinical Relevance Surgical planning of PSU resection should take into consideration the anatomy of the impingement. Regarding the extent of resection subtotal ligament sparing resection or resection to the lower margin have been suggested. Osteoporosis can increase your risk of an ulnar styloid fracture. This could happen when playing sports, falling off a bike, having a car accident, or just falling hard as you trip over something. Der Processus styloideus ulnae, kurz PSU, ist der Griffelfortsatz der Elle ().Er überragt nach distal das Caput ulnae.Sein abgerundetes Ende dient den Fasern des Ligamentum collaterale carpi ulnare als Ansatz. A transverse resection is described as the treatment of choice. The most common cause of ulnar styloid fracture, or any other wrist fracture, is falling onto an outstretched arm. Literature Review Arthroscopic resection has emerged as an alternative to the traditional open PSU resection for the treatment of styloid impaction syndrome. After failed conservative treatment, a partial oblique arthroscopic resection of the PSU and simultaneous TFCC reinsertion were performed with uneventful recovery. Case Description A patient with a severely elongated processus styloideus ulnae (PSU) with a chronic impaction of the distal-radial margin against the triquetrum suffered a traumatic triangular fibrocartilage complex (TFCC) Palmer 1B rupture and DRUJ instability. Background Open or arthroscopic partial resection of the elongated ulnar styloid is the surgical treatment of choice for ulnar styloid impaction syndrome.
