Upper cervical technique

BACKGROUND: Osteosynthesis of unstable atlas fractures preserves joint motion and therefore has a distinct advantage over a range of treatment procedures. To prevent the potential disadvantages associated with osteosynthesis, a new atlas lateral mass screw-plate (LMSP) system has been designed. However, the biomechanical role of using the LMSP system in atlas internal fixation is not known. The aim of this study was to compare the biomechanical stability of a new LMSP with traditional posterior screw and rod (PSR) fixation techniques on the occipitocervical junction (C0-C2) through finite element analysis...

AIM: To evaluate the safety and accuracy of C1 and C2 pedicle screw placement using a three-dimensional (3D)-printed double template and compare them with those of the conventional method in a clinical study. MATERIAL AND METHODS: DICOM format data from 60 cases with C1-C2 instability were obtained after computed tomography (CT) was performed. A total of 32 cases underwent surgery via the free-hand technique, whereas 28 cases underwent surgery via a 3D-printed "pointing-drilling" guide template...

The surgical treatment of Jefferson fractures generally involves solid fusion, which limits the range of motion of the upper cervical spine. Herein, we present a case of a Jefferson fracture that was surgically treated using direct C1 posterior arch screw reduction and osteosynthesis instead of fusion surgery. Postoperative computed tomography (CT) and plain radiography revealed that both C1 posterior arch screws were well positioned, and placing lag screws at the C1 level played a key role in fracture reduction...

STUDY DESIGN: Experimental porcine anterior cervical discectomy and fusion (ACDF) model: a proof-of-concept study. OBJECTIVE: The effect of monetite synthetic bone graft containing calcium pyrophosphate (Ca-PP) and β-tricalcium phosphate (β-TCP) on cervical spinal fusion in a non-instrumented two-level large animal model. SUMMARY OF BACKGROUND DATA: ACDF is the gold standard surgical technique for the treatment of degenerative cervical spinal diseases...

INTRODUCTION: Maxillary expansion is a fundamental interceptive orthodontic treatment, which can be achieved through either a rapid expansion protocol or functional devices. However, no data exist about the efficacy of functional devices in achieving skeletal expansion. Therefore, the aim of this study was to compare the effects of the rapid palatal expander (RPE) and the function-generating bite type M (FGB-M) on the transversal dimension of the maxilla, and on the maxillary and mandibular dental arch width...

Objectives  Representing approximately 22% of cervical spine injuries, upper cervical spine injuries are becoming more frequent with the increase in road traffic accidents. The purpose of our study is to evaluate the results of our surgical series and to compare them with the literature. Materials and Methods  In this monocentric retrospective study of over three years (June 2019-May 2022), all the patients with traumatic injuries of the upper cervical spine with a surgical treatment and a minimum of 12 months follow-up were included...

Transspinal direct current stimulation (tsDCS) is a non-invasive technique used to modulate spinal cord activity. However, the effects and mechanisms of this stimulation are currently not comprehensively known. This study aimed to estimate the effect of different intensities of tsDCS applied at the level of cervical enlargement of the spinal cord (C7-Th1 segments) on the excitability of the corticospinal system (CSS) and the correction of motor skills in healthy subjects. The effect of tsDCS was estimated by the motor-evoked potentials (MEP) elicited by transcranial magnetic stimulation (TMS) in the primary motor cortex (M1)...

INTRODUCTION: In a multilevel cervical laminoplasty operation for patients with cervical spondylotic myelopathy (CSM), a partial or complete C3 laminectomy may be performed at the upper level instead of a C3 plated laminoplasty. It is unknown whether C3 technique above the laminoplasty affects loss of cervical lordosis or range of motion. METHODS: Patients undergoing multilevel laminoplasty of the cervical spine (C3-C6/C7) at a single institution were retrospectively reviewed...

Stroke is a major disorder of the central nervous system that poses a serious threat to human life and quality of life. Many stroke victims are left with long-term neurological dysfunction, which adversely affects the well-being of the individual and the broader socioeconomic impact. Currently, post-stroke brain dysfunction is a major and difficult area of treatment. Vagus nerve stimulation is a Food and Drug Administration-approved exploratory treatment option for autism, refractory depression, epilepsy, and Alzheimer's disease...

Multiple approaches for instrumentation of the upper cervical spine have evolved to treat atlantoaxial instability which, until the 20th century, was largely considered to be inoperable and managed nonsurgically with immobilization. Surgeons set out to provide safe and effective approaches in a clearly dangerous and technically complex anatomic region. It is important to provide a historical analysis of the evolution of techniques that have shaped C1-C2 instrumentation, and how the diligent efforts of surgeons to improve the biomechanical stability and fusion rates of their constructs eventually led to the prevailing Harms technique...

Cervical spondylosis is a non-specific degenerative of cervical spine which results in spinal canal and nerve root foramen stenosis. The stenosis of the canals results in injury of spinal cord and nerve root. The nerve root compression causes a various symptom, such as referred pain and numbness in neck and upper extremities. Motion sensors allow for the tracking and observation of cervical movement activities with the purpose of preventing cervical spondylosis. In the proposed study, Inertia Measurement Unit (IMU) sensors and comparative 2- Dimensional Motion Capture (2D-MC) system were considered to determine the effective of cervical range of motion in various environments...

Despite the prevalence of neck pain, evidence is lacking regarding the relationship of pathophysiology to function in people with neck conditions. Although movement-based diagnoses based on directional preference (DP) are described for lumbar spinal conditions, how these diagnoses guide interventions is not supported in the Cervical Spine Clinical Practice Guidelines. To date, there are no case studies in the literature that demonstrate the efficacy of cervical spine management based on a rotation DP. This case series highlights patient response to repeated end-range neck movements to inform DP and how the cervical flexion rotation test (CFRT) was used as a clinical baseline to assess mechanical and symptomatic changes...

INTRODUCTION: Atlas ring fractures, which account for 1.3% of all spinal fractures, are predominantly managed conservatively. However, in certain cases, surgical treatment may be necessary depending on the type of fracture, degree of comminution, fracture location, and associated ligamentous injuries. Surgical stabilization frequently results in a posterior C1-2 or C0-2 fusion, which restricts movement, particularly craniocervical rotation. Coronal split fractures of the lateral mass need to be reduced and fixed due to dislocation, instability and secondary osteoarthritis...

OBJECTIVE: To determine radiation dose volume threshold in predicting the development of hypothyroidism in cancer patients following neck irradiation. METHODS: This is a cross sectional follow up study for patients who had been previously irradiated, prior to enrolment in the study. We have done thyroid dose-volumetric analysis on 120 histologically proven cancer patients in the age group of 18-75 years who received neck irradiation as a part of their definitive or adjuvant radiotherapy with three-dimensional conformal or intensity-modulated radiotherapy technique (3D -CRT or IMRT) and completed at least six months post-radiotherapy...

The current scientific knowledge and guidelines in bone and soft tissue augmentation suggest the use of staged surgical workflows as the gold standard of regenerative procedures during implant therapy. In this context, the process is always the same, regardless of the techniques applied: an alternate series of surgical acts that follow one another after the completion of a specific period of osseointegration or graft maturation. As a result, the overall surgical treatment is often long and invasive and induces scar tissue formation...
