fracture of processus styloideus

OBJECTIVE: Anatomical reduction of dislocated fractures using an angle-stable hook plate. Surgical revision of symptomatic nonunions with the aim of bone regeneration. INDICATIONS: Dislocated fractures of the ulnar styloid process with involvement of the ulnar fovea. Combined fractures with instability of the distal radioulnar joint and symptomatic nonunions. CONTRAINDICATIONS: Undisplaced fractures of the ulnar styloid process and asymptomatic nonunions...

OBJECTIVE: To analyze effects of fracture of processus styloideus ulnae on prognosis in the treatment of distal radial fracture of type C according to AO classification. METHODS: This was a retrospective case-control study, and the information was got ten through case evaluation and follow-up, including sex, age, patient satisfaction, Gartland & Werley score and radiographic score. There were 76 patient treated with open reduction and plate fixation in People's Hospital Affiliated to Peking University from July 2006 to July 2011...

OBJECTIVE: To evaluate the changes in stability of the wrist after experimental traumatic triangular fibrocartilage complex (TFCC) lesions, and to provide basic theoretical criteria for clinical treatment. METHODS: Fourteen adult cadaver upper extremities specimens were included. Two of 14 specimens were tested in pre-experiment. The specimens were tested in a INSTRON 8874 biomechanics measuring instrument. First a dorsal arthrotomy (ART) was performed, and second test was with 1 of 4 different experimental lesions according to Palmer's classification of traumatic TFCC lesions (n=3)...
