Chronic encapsulated intracerebral hematoma (CEIH) is a rare disease which is believed to be caused by angiographically negative vascular malformations. CEIH has the following characteristic findings: 1. It affects all age groups 2. Clinical symptoms progress slowly after sudden onset. Often there is a latency of months or years 3. There is no correlation(More)
This retrospective study aims to discuss and compare our results with those previously mentioned in the literature with regard to C5-C6 radiculopathy that occurs after decompression carried out for cervical spondylotic myelopathy. There are few reports in the literature referring to the incidence of the C5-C6 radiculopathy following cervical decompression(More)
The aim of our attempts and trials was to develop a minimally invasive posterior approach to the spine which utilises the smallest access to the target without additional harmful effects on the stability of the spine and at the same time allows excellent dealing with the lesions depending on the advantage of the operative microscope in providing 3(More)
UNLABELLED Surgery on the degenerative cervical spine disorders aims at decompression of the neural structures and restoring the physiological profile of the cervical spine. The aims of internal fixation are to gain primary stability, introduce a bony fusion and to correct the shape of the spine. The present study will give answers to the following(More)
Lumbar discectomy is one of the most frequent neurosurgical and orthopaedic procedures. In this study, a series of 43 consecutive patients operated with a minimally invasive technique referred to as "microscopically assisted percutaneous nucleotomy" (MAPN) is presented. After a follow-up period of 3 months, every patient was seen clinically, and after 12(More)
UNLABELLED The aim of this prospective study is to evaluate the efficacy of a less invasive approach for the operative treatment of lumbar canal stenosis. Using transmuscular dilatation this technique minimises surgical trauma. Through a working channel with a 11 mm outer diameter and under operative microscope guidance, decompression of the neural elements(More)
This paper describes a limited exposure for posterior C1-C2 arthrodesis aided by percutaneous transarticular fixation. The purpose of this study was to report the fusion rate using the aforementioned method. Fifty-seven patients (54 females and three males) with C1-C2 instability due to rheumatoid disease constituted the material of this study. The exposure(More)
Spondylodiscitis is considered to be the main cause of epidural abscess. In this report, the authors present their concept for the management of the extended epidural abscess that occurs in combination with spondylodiscitis. It consists of debridement and fusion for spondylodiscitis together with epidural abscess drainage using a microscopically assisted(More)
