Purpose: The primary aim of dynamic stabilization is to stabilize the spine and preserve function without overstressing adjacent segments, which is a potential risk of fusion surgery. However, direct comparative analyses of the two approaches are still limited, and little is known about the association of patient-reported outcomes with these treatment options.
Objective: To compare the clinical outcomes of dynamic posterior stabilization using the DSS Stabilization System (Paradigm Spine, LLC, New York, New York, United States) versus posterior lumbar intervertebral fusion (PLIF) based on data from a spine registry.
Introduction: Dynamic stabilization of the degenerated spine was invented to overcome the negative side effects of fusion surgery like adjacent segment degeneration. Amongst various different implants DSS(®) is a pedicle-based dynamic device for stabilizing the spine and preserving motion. Nearly no clinical data of the implant have been reported so far.

The intraoperative use of image guidance devices may allow surgeons a safer, more accurate method for placing thoracic pedicle screws while limiting radiation exposure. This generic 3D imaging technique is a new generation intraoperative CT imaging system designed without compromise to address the needs of a modern OR.

To date there are no clinical studies on the Discover. Preliminary clinical and intraoperative results from a pilot study should be compared with data for other commonly used prostheses.
View Article and Find Full Text PDFA Prospective randomised controlled study was done to determine statistical difference between the standard microsurgical discotomy (MC) and a minimally invasive microscopic procedure for disc prolapse surgery by comparing operation duration and clinical outcome. Additionally, the transferability of the results was determined by a bicentric design. The microscopic assisted percutaneous nucleotomy (MAPN) has been advocated as a minimally invasive tubular technique.

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 questions: 1.

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 percutaneous technique.

Methods: In a retrospective cohort study 90% of the 51 stems implanted in our institute in the years 1993/94 51 stems were reexamined.
Background: Spinal subdural hematoma (SSDH) is an exceedingly uncommon and potentially neurologically devastating condition. Recognition of blood products in magnetic resonance imaging is a very important clue for the diagnosis of SSDH. It is generally agreed that prompt surgical evacuation should be performed before irreversible damage to the spinal cord occurs.

Patients And Methods: We investigated retrospectively 48 patients who were stabilized in a ventrodorsal approach for fractures of the thoracic spine.
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.

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 can be achieved.

Objectives: To answer the following questions: Reoperation rate after PLIF? And is there any influence of the length of fusion on the reoperation rate?
Summary Of Background Data: The use of different techniques demonstrates that there is currently no ideal procedure for lumbar fusion. The instrumented posterior lumbar interbody fusion (PLIF) shows a comparable success rate to the so-called 360 degrees fusion techniques (combined dorsoventral spondylodesis) without the need of an anterior approach.
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 procedures. Some authors believe that the postoperative cord shift is the most likely cause.

Cervicogenic headache was noted in 117 of 299 patients (40%). 73 of those patients were treated conservatively.
View Article and Find Full Text PDFDegenerative cervical disorders predominantly lead to anterior spinal cord compression (by bony spurs at the posterior margin of the vertebral body or by degenerated disc), which may be central and/or foraminal. In a smaller percentage of cases, there is encroachment of the canal mainly from posterior by bulging yellow ligaments or bony appositions, resulting in compression syndromes of roots or spinal cord. The aim of this work is to present a minimally invasive posterior approach avoiding detachment of muscles for the treatment of cervical radiculopathy and myelopathy.

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 months, telephone enquiries were performed by the first author.
View Article and Find Full Text PDFThe 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 dimensional view of the operative field. In the period between May 1998 and February 2001, 356 patients were treated for different spinal disorders using this approach. The approach was applied in 299 surgeries for lumbar disc herniation and we called the procedure: microscopic assisted percutaneous nucleotomy (MAPN).
