Abstract

AIM: We present a series of 16 patients who underwent occipitocervical fixation with occipital bone hooks used as a substitute for occipital screws for the treatment of occipitocervical instability. MATERIAL and METHODS: In this technique; instrumentation was started following the decompression with insertion of screws into lateral masses. At the occipital level, two symmetrical burr holes were drilled and two occipital bone hooks were inserted into each burr hole with an inverted position with respect to each other. Afterwards, rod-plates were placed and locked on the hooks and screw heads. Bone grafting was also performed to achieve a solid fusion. RESULTS: There were no neurological or vascular complications associated with this technique. No infection-related complications or hematomas were observed. Cerebro-spinal fluid leaks (CSF) occurred when the burr holes were drilled in 4 patients; however, these ceased when the occipital bone hooks were inserted. There were no cases of postoperative CSF fistula or pseudo-meningocele formation. No instrumentation problem was noted in any of the cases during the follow-up period. CONCLUSION: Relatively long term (average 30.44 months) evaluation of the technique in terms of stability is satisfactory with no neurological, vascular or other major complications. However, further biomechanical studies are needed.

Özet

AMAÇ: Bu çalışmada, oksipital vidalar yerine oksipital kemik kancaları kullanılarak yapılan 16 oksipitoservikal fiksasyon olgusu analiz edilmiştir. YÖNTEM ve GEREÇLER: Nöral dekompresyon işlemini takiben servikal vertebraların yan kitlelerine vidalar yerleştirildi. Oksipital skuama üzerine 2 adet simetrik burr-hole açılarak fiksasyon seti ile birlikte gelen 2 adet oksipital kanca burr-hole içerisine birbirlerine ters yönlerde yerleştirildi. Daha sonra rodlar yerleştirilerek fikasayon tamamlandı. Allograft kulanılarak füzyon yapıldı. BULGULAR: Hastaların hiçbirisinde nöral veya vasküler komplikasyon olmadı, enfeksiyon ve hematom görülmedi. 4 hastada burr-hole açılırken BOS sızıntısı oldu, ancak bu sızıntı kancalar yerleştirildikten sonra kesildi. Hiçbir hastada postoperatif dönemde psödomeningosel veya BOS kaçağı olmadı. Hastaların izlemi süresince herhangi bir enstrüman problem olmadı. SONUÇ: Ortalama 30,44 aylık izlem süresince hiçbir vasküler ve nörolojik komplikasyon olmadığı gibi stabilite problemi de olmadı. Daha güvenli bir stabilizasyon yöntemi olarak kullanılan oksipital kemik kancaları için yine de ileri biyomekanik çalışmalar gereklidir.
