[Infected pseudarthrosis of the symphysis with persisting instability : Revision osteosynthesis with tantalum cage and silver ionized ITS plate after peri-implant infection with MRSE after osteosynthetic stabilization of a type C pelvic injury].

Overall symptomatic pseudathrosis after pelvic ring fracture is rare. A pseudarthrosis of the dorsal pelvic ring often leads to persisting pain due to instability and needs a consequent treatment strategy. Often a bacterial infection can be found in persisting pseudarthrosis notably in the anterior pelvic ring region.

Long-term results after thoracoscopic anterior spondylodesis with or without posterior stabilization of unstable incomplete burst fractures of the thoracolumbar junction: a prospective cohort study.

Background: Minimally invasive, thoracoscopic anterior spondylodesis (MIAS) is an established treatment for burst fractures of the thoracolumbar spine. Good restoration of the local sagittal alignment and good functional results have been reported. The aim of this study was to evaluate long-term results of MIAS in patients with incomplete burst fractures and to analyze the influence on global sagittal alignment, clinical outcomes, and adjacent segment degeneration.

Clinical and radiological evaluation of thoracic spine fractures with or without sternal fracture: is there a need for ventral stabilization?

Objective: The treatment of thoracic spine (TS) fractures with additional sternal fractures compared to TS fractures without sternal fractures is discussed controversionally, because in some studies it was stated that sternal fractures decrease the thoracic stability. We hypothesized that both types of fractures can be treated the same way by posterior stabilization alone.

Methods: A total number of 69 patients with thoracic fractures, with or without additional sternal fractures, were examined, regarding the angle of kyphosis after fracture, postoperatively and after 6 and 12 months.

Influence of Preoperative Magnetic Resonance Imaging on Surgical Decision Making for Patients with Acute Traumatic Cervical Spinal Cord Injury: A Survey Among Experienced Spine Surgeons.

Objective: Early decompression after acute spinal cord injury (SCI) is recommended. Acute care is crucial, but optimal management is unclear. The aim of this study was to investigate the role of preoperative magnetic resonance imaging (MRI) in addition to computed tomography (CT) in surgical decision making for acute cervical SCI.

Treatment of Fractures of the Thoracolumbar Spine: Recommendations of the Spine Section of the German Society for Orthopaedics and Trauma (DGOU).

Study Design: consensus paper with systematic literature review.

Objective: The aim of this study was to establish recommendations for treatment of thoracolumbar spine fractures based on systematic review of current literature and consensus of several spine surgery experts.

Methods: The project was initiated in September 2008 and published in Germany in 2011.

Six-year outcome of thoracoscopic ventral spondylodesis after unstable incomplete cranial burst fractures of the thoracolumbar junction: ventral versus dorso-ventral strategy.

Purpose: The purpose of this study is to determine the long term-results after thoracoscopic spondylodesis particularly with respect to a ventral versus dorso-ventral treatment strategy.

Methods: In this prospective cohort study, a follow-up examination was performed in 19 patients (seven men, 12 women, average age: 37.7 years, follow-up rate: 79 %), six years after ventral thoracoscopic spondylodesis of unstable, incomplete burst fractures.

6-Year follow-up of ventral monosegmental spondylodesis of incomplete burst fractures of the thoracolumbar spine using three cortical iliac crest bone grafts.

Introduction: Autologous bone graft is the gold standard for vertebral body replacement. Currently, after modern implants for vertebral body replacement are available, controversies exist regarding the optimal implant strategy.

Patients And Methods: Between 2002 and 2003, 17 patients were included in this study, all suffering from incomplete burst fractures of the thoracolumbar spine.

Modularity of a new cementless acetabular revision cup system based on research of the anatomic variability of the pelvis.

There is a growing need for specific revision implants to meet the increasing occurrence of failed total hip arthroplasties displaying massive deficiencies in acetabular bone stock. The developed acetabular revision cup presented in this study is aimed at individual patient solutions using a multi-axial and angular stable fixation peg as well as a modular adaptable lateral flap. To obtain an optimum implant design, a database of computed tomography scans of 69 patients' pelves was collected and computational reconstruction of the pelvic bone morphology was conducted.

Synthetic studies on N-alkoxyamines: a mild and broadly applicable route starting from nitroxide radicals and aldehydes.

A broad variety of 2,2,6,6-tetramethylpiperidine-based N-alkoxyamines were prepared in a newly found reaction. By means of a copper-catalyzed fragmentation reaction of aldehyde peroxides in the presence of TEMPO or TEMPO derivatives, N-alkoxyamines were obtained in moderate to good yields.

Strategies for prevention and operative treatment of aortic lesions related to spinal interventions.

Study Design: A retrospective analysis of a case series was performed.

Objective: To give recommendations for the prevention and operative treatment of thoracic and thoracoabdominal aortic lesions in association with spinal interventions.

Summary Of Background Data: Aortic lesions after spinal interventions for traumatic vertebral fractures, segmental spondylodiscitis, or vertebral metastasis are fortunately rare, but associated with a high perioperative mortality rate and absolute numbers are unknown.

Transcostovertebral kyphoplasty of the mid and high thoracic spine.

While Kyphoplasty is increasingly becoming a recognised minimally invasive treatment option for osteoporotic vertebral fractures and neoplastic vertebral collapse, the experience in the treatment of vertebrae of the mid (T5-8)- and high (T1-4) thoracic levels is limited. The slender pedicle morphology restricts the transpedicular approach at these levels, necessitating extrapedicular placement techniques. Fifty five vertebrae of 32 consecutive patients were treated with kyphoplasty at levels ranging from T2-T8 for vertebral fractures (27 patients) or osteolytic collapse (5 patients).
