Preventive effect of risedronate on bone loss and frailty fractures in elderly women treated with anastrozole for early breast cancer.

2011

The aim of this study was to assess the effect of adjuvant anastrozole, alone or associated with risedronate, on BMD and bone fracture risk in women more than 70 years old with hormone receptor-positive early breast cancer (EBC). In a group of 51 elderly women (aged 76.4 ± 5.0 years) considered for adjuvant aromatase inhibitors for EBC, 24 patients with T-scores ≥ -2 and no prevalent fractures received anastrozole 1 mg/day (group A), and 27 patients with T-scores < -2, or with T-scores ≥ -2 and prevalent fractures (group B), received anastrozole (1 mg/day) plus risedronate (35 mg/week). Both groups received supplementation with 1 g calcium carbonate and 800 IU vitamin D per day. Differen…

High-Definition Imaging in Spinal Neuroendoscopy

2010

BACKGROUND Spinal endoscopy is still under controversial discussion. An often acclaimed critic is the poor endoscopic image quality in comparison with the microscope. Since high-definition digital cameras have recently been introduced into spinal neuroendoscopy, the aim of the current study is to examine whether superior image quality has a relevant impact on intraoperativen orientation. MATERIAL AND METHODS A lumbar endoscopic discectomy was recorded simultaneously in High-Definition resolution (HD) and Standard-Definition resolution (SD). 10 experienced spinal surgeons were asked to identify predefined as well as not predefined anatomic structures in HD and SD resolution. Additionally, th…

Posterior epidural intervertebral disc migration and sequestration: A systematic review

2022

Posterior epidural intervertebral disc migration and sequestration (PEIMS) is a rare and debilitating complication of degenerative disc disease. Radiological differential diagnosis is often challenging, complicating the accurate planning of appropriate treatment strategies. We systematically reviewed the literature on PEIMS, focusing on clinical-radiological features and available treatments. PubMed, Scopus, Web of Science, and Cochrane were searched to include studies reporting clinical data of patients with PEIMS. Clinical characteristics, treatment strategies, and functional outcomes were analyzed. We included 82 studies comprising 157 patients. Median age was 54 years (range, 19-91). PE…

Lumbar Disc Degeneration and Sagittal Flexibility

1996

It is uncertain whether intervertebral disc degeneration is associated with reduced or increased flexibility, although lumbar flexibility is known to reduce with advancing age. This cross-sectional study of 214 middle-aged men attempted to determine the influence on lumbar sagittal flexibility from intervertebral disc degeneration parameters measured from magnetic resonance images (disc height, signal intensity, bulging, osteophytes). Multivariate analyses showed that a reduced extent of lumbar flexibility could be accounted for by the combined effect of decreasing disc height together with increasing age, weight, and back pain frequency. Although it remains possible that single degenerate …

Bionate Lumbar Disc Nucleus Prosthesis: Biomechanical Studies in Cadaveric Human Spines.

2022

Design: cadaveric spine nucleus replacement study. Objective: determining Bionate 80A nucleus replacement biomechanics in cadaveric spines. Methods: in cold preserved spines, with ligaments and discs intact, and no muscles, L3-L4, L4-L5, and L5-S1 nucleus implantation was done. Differences between customized and overdimensioned implants were compared. Flexion, extension, lateral bending, and torsion were measured in the intact spine, nucleotomy, and nucleus implantation specimens. Increasing load or bending moment was applied four times at 2, 4, 6, and 8 Nm, twice in increasing mode and twice in decreasing mode. Spine motion was recorded using stereophotogrammetry. Expulsion tests: cyclic c…

Facio-auricle-vertebral spectrum (Goldenhar's syndrome): Clinical study of 10 pediatric patients

2002

Goldenhar's syndrome - also known as facio-auricolo-vertebral spectrum - is due to a developmental defect of cranio-facial and vertebral structures, and is interpreted as a disruption. Exogenous factors, such as gestational diabetes or ovopathies, have been involved in its aetiology. The pathogenesis of Goldenhar's syndrome seems to be vascular in most of cases, due to the interruption of blood supply to the branchial and vertebral areas during embryonic development. Ten cases of facio-auricolo-vertebral spectrum of different ages are described, in view of a better delineation of its phenotype. This report can contribute to a better knowledge of the phenotype of facio-auricolo-vertebral spe…

Totale Spinalanästhesie im Notarztdienst

2002

Die vorliegende Kasuistik beschreibt den auserst seltenen Fall einer auserklinisch aufgetretenen totalen Spinalanasthesie. Neben dem initialen Management werden die weiteren moglichen Komplikationen von paravertebralen Injektionen fur die differenzialdiagnostische Uberlegung erlautert. Das Erkennen der Symptomatik kann neben der lebensrettenden Therapie im weiteren Verlauf bei gesichertem kausalen Zusammenhang eine kostenintensive Ausweitung der Diagnostik und Therapie verhindern. In der Regel behalten die Patienten bei adaquater Notfalltherapie keine bleibenden Schaden zuruck. Fur die Anwender von paravertebralen Injektionstechniken ergibt sich, dass adaquate personelle und apparative Vora…

Prädiktoren der Lebensqualität nach orthopädischer Behandlung lumbaler "bandscheibenbedingter" Rückenschmerzen/ Predictors of quality of life after o…

2003

Zusammenssung Fragestellung: Untersuchung der pradiktiven Bedeutung organpathologischer, psychischer und psychosozialer Parameter fur die Lebensqualitat bei Katamnese von Patienten mit lumbalen "bandscheibenbedingten" Beschwerden. Methode: In dieser prospektiven Studie wurden 109 Patienten mit lumbaler "bandscheibenbedingter" Schmerzsymptomatik vor und ein Jahr nach stationarer orthopadischer Behandlung hinsichtlich ihrer Lebensqualitat und psychischen Belastung untersucht. Der Behandlungserfolg wurde mit Hilfe der deutschen Version des Short Form Health Survey (SF-36), die psychische Belastung mit Hilfe der Symptom-Checkliste 90 (SCL-90-R) und die Krankheitsbewaltigung mit Hilfe des Freibu…

The Role of Endoscopy in the Treatment of Acute Traumatic Anterior Epidural Hematoma of the Cervical Spine: Case Report

1997

OBJECTIVE AND IMPORTANCE: Epidural hematoma (EDH) of the spine represents an uncommon neurosurgical disorder that sometimes requ;res emergent surgical decompressive therapy. Traumatic EDH of the cervical spine is exceedingly rare. The hematoma is usually located dorsally in the epidural space. We present one case of acute EDH located ventrally in the cervical spine. Special emphasis is placed on the role of spinal endoscopy in surgical treatment. CLINICAL PRESENTATION: After a fall from a tree, a 69-year-old man with rapidly increasing tetraparesis was referred to our institution. Plain films of the cervical spine revealed nothing abnormal. The results of computed tomography were highly sus…
