THE ACCESSORY ULNAR STYLOID PROCESS

The accessory ulnar styloid process is an uncommon variation in the wrist. This ossicle is generally believed to be asymptomatic but when traumatized, it can be responsible for the pain in the ulnar border of the wrist. Identification of this variation is of importance because the injury may occur as a result of chronic repetitious trauma and the ossicle may easily be mistaken for a fracture. In our study; the incidence, the types and female/male percentages for the accessory ulnar styloid process were investigated by means of radiograps from volunteers and clinic cases. This ossicle was encountered in 10 cases as; incidence 2.5%, male/female persentage 7/3 and one of them is symptomatic. Clinical importance of this variation was discussed by the knowledge of literature.

AKSESUAR ULNAR STÝLOÝD

Aksesuar processus styloideus ulnaris el bileðinde nadir olarak görülen genellikle asemptomatik bir varyasyondur. Fakat travmatize olduðu zaman el bileði ulnar kenarýnda bir aðrýdan sorumlu olabilir. Kronik, tekrarlayan travmalarýn el bileðinde injüri oluþturabilmesi ve tanýda kolayca bir kýrýk ile karýþabilmesi gibi sebeblerle bu varyasyonun iyice tanýnmasýna ihtiyaç vardýr. Bu amaçla, gönüllü ve klinik olgulardan elde edilen grafiler üzerinde aksesuar processus styloideus ulnaris ve varyasyonlarý araþtýrýldý. Bu kemikçiðin insidensi %2.5, erkek/kadýn oraný 7/3 ve bir klinik olgu semptomatik bulundu. Literatür bilgileri ile bu varyasyonun klinik önemi tartýþýldý.
