A 77-year-old woman had a total luxation of C5-C6 after falling 1 m down a staircase. She presented with atypical symptoms, i.e. shoulder- and back pain, and later pareses of the left arm. The initial clinical findings did not warrant radiography, which delayed the correct diagnosis of her serious condition. When diagnosed she received surgical stabilization of her fractures. We recommend the use of a validated set of rules for radiography, e.g. Canadian C-spine Rule or National Emergency X-radiography Utilization Study low-risk criteria on all elderly patients admitted after fall-trauma to rule out cervical injury even with no typical symptoms...

INTRODUCTION: Ankylosing spondylitis (AS) affects 0.5% of the population. Alteration of the biomechanical properties of the spine related to AS explains the high prevalence of traumatic vertebral fractures and risk of instability. At admission, 65% of patients present neurological signs. There are no reported studies regarding secondary neurological deterioration. The aim of this study was to evaluate the rate of secondary neurological deterioration before surgical treatment of spine fracture in a context of AS...

INTRODUCTION: Cervical subaxial malalignment due to complete or partial post-traumatic dislocation is generally associated to neurological impairment of ranging severity. Literature lacks reporting this entity in patients with no neurological issues. Cervical traction is not widely accepted in treating this kind of injury, due to its potential for neurological damage, although surgery seems to represent the gold standard. MATERIALS AND METHODS: We studied in detail 18 cervical subaxial severe dislocations and ptosis, especially analyzing 2 personal cases plus 5 from the literature without neurological impairment...

We evaluated treatment by posterior approach and its results for unilateral and bilateral facet dislocation of the lower cervical spine. Fracture reduction and ultimate stabilization of low cervical fractures located between C3 and C7 depend on the mechanism of the lesion and the resulting affectation of the osteoligamentary structures. The varied surgical approaches to fractures with unilateral or bilateral luxation include anterior, posterior, and combined. No surgery is performed if a conservative approach is used...

The term 'coccygodynia' means the pain in the tailbone area (os coccygis; coccyx). Due to the sitting intolerance, coccygodynia can significantly disturb the quality of life. Coccygeal disorders that could be manifested in coccygodynia are injuries (fracture, subluxation, luxation), abnormal mobility (hypermobility, anterior and posterior subluxation or luxation of the coccyx), disc degeneration at sacrococcygeal (SC) and intercoccygeal (IC) segments, coccygeal spicule (bony excrescence), osteomyelitis and tumors...

INTRODUCTION: Even if performed by qualified physical therapists, spinal manipulation and mobilization can cause adverse events. This holds true particularly for the cervical spine. In light of the substantial risks, the benefits of cervical spine manipulation may be outweighed by the possibility of further injury. CASE PRESENTATION: We present the case of a 56-year-old Caucasian man with Forestier's disease who went to see a physiotherapist to relieve his aching neck while on a holiday trip...

The authors present the advantages and disadvantages of the Denis and AO classifications based on a review of classical and recent literature concerning the evolution of classification of thoracolumbar spine conditions. The newest classification of fractures proposed by Vaccaro (TLICS - Thoracolumbar Injury Classification Severity Score) is discussed in detail. Special attention is given to instability in these fractures. The principles of modern operative treatment are briefly discussed. Short transpedicular segmental stabilization and immobilization is a commonly accepted approach in unstable fractures with neurological deficits...

The aims of this work were to re-evaluate the moments of resistance (MoRs) of the vertebral column proposed by Slijper (1946) in the dog and to study the relationship between the MoRs and the frequency distribution of vertebral traumas in the same species. The spine (C2-L7) of four dogs was measured to obtain MoRs and subsequently scanned with a dual-energy X-ray absorptiometer (DXA). These findings were then analysed retrospectively the frequency distribution of canine vertebral fractures and luxations, diagnosed radiographically at a referral practice...

PURPOSE: Instable upper cervical spine injuries (CSI) in very young children are rare and consecutively only few data on the treatment and operative approaches exist in the literature. Hence, we suggest an operative strategy in the case of a 15-month-old infant treated for an instable CSI at the level of C2/3 at our department. Detailed steps of the operation with special consideration to the challenging anatomy of the immature spine are presented. METHODS: A toddler suffered a CSI without neurological deficits after a stair fall...
