We present a rare fatal complication of an occipital condylar fracture. The patient was initially neurologically intact, but showed secondary clinical deterioration. Imaging revealed extensive extra-axial hemorrhage at the craniocervical junction and an acute obstructive hydrocephalus. MR imaging demonstrated a T2 hyperintens signal in both the lower brainstem and upper cervical spinal cord, likely caused by the extra-axial hemorrhage. As prognosis was estimated infaust, supportive treatment was discontinued and the patient died soon thereafter...

BACKGROUND: Older adults represent a growing proportion of trauma patients treated in the United States, and cervical spine (c-spine) fracture is an injury that is increasingly common in this population. Neck pain is a major component of current clinical clearance guidelines, but some older adults with c-spine fractures report no neck pain after injury. The objective of this study was to investigate the frequency at which c-spine fractures were unassociated with neck pain in an aging population...

Odontoid process fracture accounts for 5% to 15% of all cervical spine injuries, and the rate is higher among elderly people. The anterior cannulated screw fixation has been widely used in odontoid process fracture, but the fixation strength may still be limited under some circumstances. This study aims to investigate the biomechanical fixation strength of expansive double-threaded bi-directional compression screw (EDBCS) compared with cannulated lag screw (CLS) and improved Herbert screw (IHS) for fixation of type II odontoid process fracture...

INTRODUCTION: Injury is a major cause of premature death and disability in East Africa, and high-quality pre-hospital care is essential for optimal trauma outcomes. The Rwandan pre-hospital emergency care service (SAMU) uses an electronic database to evaluate and optimize pre-hospital care through a continuous quality improvement programme (CQIP), beginning March 2014. MATERIALS AND METHODS: The SAMU database was used to assess pre-hospital quality metrics including supplementary oxygen for hypoxia (O2), intravenous fluids for hypotension (IVF), cervical collar placement for head injuries (c-collar), and either splinting (splint) or administration of pain medications (pain) for long bone fractures...

Clinical case report and review of the literature. This is the first case of primary leiomyoma in an immunocompetent woman without previous history of uterine leiomyoma being reported in the literature to the best of our knowledge. Leiomyoma, a type of smooth muscle cell tumor, involving the vertebra is extremely rare. There were very few primary leiomyoma in patients with AIDS or in the immune-suppressed patients. This 48-year-old female came with H/o neck pain, weakness and bladder retention. On examination, tone increased in all four limbs, power on the right side of the limbs 4/5, power on the left upper limb 0/5, lower limb 3/5, left plantar was up going, decreased sensation over the left second cervical vertebra (C2) dermatome and all modalities decreased below C2...

BACKGROUND AND AIMS: Restriction of head and neck movements prevents the alignment of the oral, pharyngeal, and laryngeal axes and increases the incidence of difficult tracheal intubation in patients with cervical spine fractures. Video laryngoscopes have gained an important role in the management of difficult intubation, especially in situations with limited head and neck movements. This study compares the success of intubation using Macintosh laryngoscope assisted Bonfils(®) fiberscope (ML-BF) with Truview(PCD) video laryngoscope (TV) in patients with simulated restricted head and neck movements...

In 2004, a 61-year-old male presented to a chiropractic clinic complaining of neck pain after hearing a 'crunch' when getting out of bed that morning. The initial history intake and physical examination identified no red flags or indications for the patient's pain, with the exception of traction being pain-provoking. Conventional radiographs were ordered, which identified a pathological burst fracture of the fourth cervical vertebra. This Imaging Case Review (ICR) is to provide clinicians with a follow-up to the patient's care and current state...

Reconstruction of late esophageal perforation usually requires flap surgery to achieve wound healing. However, restoring the continuity between the digestive tract and retropharyngeal space to allow for normal swallowing remains a technical challenge. In this report, we describe the use of a thin and pliable free adipofascial anterolateral thigh (ALT) flap in a 47-year-old tetraplegic man with a history of C5-C6 fracture presented with a large posterior esophagus wall perforation allowing an easier flap insetting for a successful wound closure...

BACKGROUND: Primary spinal osseous tumors are rare, yet they represent a difficult treatment paradigm because of the complexities of tumor resection and significant resistance to chemotherapy and radiation therapy. The geographic distribution of primary spinal osseous tumors throughout the world appears to be quite variable, with a very low incidence reported in Asian countries. METHODS: Data on 1209 cases of primary spinal osseous malignant and benign tumor cases diagnosed during the 20-year period of 1995 through 2015 in eastern China were analyzed...

BACKGROUND: Osteoporotic hip fractures are associated with high mortality and morbidity in people of advanced age; however, few studies have investigated the complication rates in nonagenarians. In this study, we applied a competing risk analysis to estimate the mortality, readmission, and reoperation rates after surgery for hip fracture among nonagenarians. METHODS: A total of 11,184 nonagenarians (aged ≥ 90) who received surgery for hip fracture during the period 1 January 1997 and 31 December 2010 were selected from Taiwan's National Health Insurance (NHI) database...

Posterior instrumented fusion of the cervical spine is a common surgical procedure in the treatment of cervical subluxation, fractures, and stenosis. Although malpositions are commonly seen, it is rare to observe the malposition of the rod or interconnection because of hardware failure. A 62-year-old woman with spastic tetraparesis as a sequel to pediatric meningitis with C1 -C2 cervical subluxation and myelomalacia had undergone laminectomy of C1 and C1 lateral mass and C2 bilateral pedicular screw fixation...

STUDY DESIGN: A retrospective cohort, radiographic study. OBJECTIVE: To assess the diagnostic accuracy of bone scintigraphy (BS) for the detection of cervical spine metastases in oncological patients. SUMMARY OF BACKGROUND DATA: BS remains the modality of choice for the screening of bone metastases, because of its feasibility in whole-body scanning and its widespread availability at low cost. Current practice guidelines for patients with malignant diseases recommend BS imaging as the primary screening method for detecting both axial and appendicular skeletal metastases...

BACKGROUND: Bone tissue anatomy, density and porosity vary among subjects in different phases of life and even within areas of a single specimen. The optical characteristics of changes in bone tissue are analyzed based on these properties. Photobiomodulation has been used to improve bone healing after surgery or fractures. Thus, knowledge on light propagation is of considerable importance to the obtainment of successful clinical outcomes. OBJECTIVE: This study determines light penetration and distribution in human maxillary and mandibular bones in three different regions (anterior, middle, and posterior)...

INTRODUCTION: Motion preserving techniques in C1 ring fractures are increasingly used especially in young patients. Therefore, lateral mass screws are inserted in the first vertebra and connected by a rod. The purpose of this study was to determine safe zones regarding the vertebral arteries and the medulla oblongata for optimal lateral mass screw positioning when fusing the C1-ring. MATERIALS AND METHODS: Images of the cervical spine of 50 patients (64-line CT scanner) were evaluated and virtual screws were positioned in both lateral masses of the first vertebra using 3D-reconstructions of CT scans...

Os odontoideum is a separate odontoid process from the body of the axis. It is the most common anomaly of the odontoid process. Patients with this condition can be asymptomatic or present with a wide range of neurological dysfunctions. It may cause cervical instability, atlantoaxial dislocation and myelopathy. This anomaly can mimic Type I and II odontoid fractures. There is a role for conservative treatment of an asymptomatic incidentally found, radiologically stable and non-compressive os odontoideum. However, surgical treatment has a definitive role in symptomatic cases...
