    AIM: The aim of this study is to compare the different types of fusion materials known as PEEK cages used during anterior cervical discectomy (ACD) surgery. MATERIAL and METHODS: A total of 67 patients were operated and evaluated retrospectively under two groups (group A: 35 PEEK cage patients, group B: 32 bladed PEEK cage patients) between 2009 and 2013. Preoperative and postoperative (postoperative first day, postoperative 1st, 3rd and 12-24th mo) images were obtained. The cervical disc heights, cervical and segmental lordotic angles of the operated levels were calculated. Pain assessment was performed and fusion rates were also compared. Mann-Whitney U test was applied to compare the outcomes. RESULTS: The pain scores (especially for arm pain) were decreased significantly in both groups after surgery regardless of the type of operation technique (P<0.05). There were no significant differences between both groups at the disc height measurements of operated levels in postoperative periods (P>0.05). In addition to these; there was no significant difference between both groups of segmental and cervical lordodic angles in postoperative periods (P>0.05). There was no statistically significant difference between the fusion rates and pain scores of both groups (P>0.05). CONCLUSION: The PEEK cage and bladed PEEK cages can be used safely to obtain fusion after ACD.

    Patients with Chiari Malformation Type 2 in VP Shunt Rare Complication
    (Derman Medical Publ, 2014) Akman, Tarik; Guven, Mustafa; Aras, Adem Bozkurt; Cikman, Oztekin; Safak, Ozbey; Karaaslan, Oznur; Akman, Canan
    Spontaneous perforation of the bowel caused by VP shunt is a very rare complication, and if unnoticed will be fatal. Two years previously our case with Chiari malformation type 2 had revision of the distal end of the VP shunt and also myelomeningocele ends on at the end of the infant period. The case was examined laparoscopically and found to have rare spontaneous intestinal perforation at the transverse colon splenic flexure level, followed by anal prolapse of the peritoneal catheter.
