Objective: The purpose of this study is to evaluate the efficacy and safety of 3-level hybrid surgery (HS), which combines fusion and cervical disc replacement (CDR), compared to 3-level fusionin patient with cervical spondylosis involving 3 levels. Methods: Patients in the anterior cervical discectomy and fusion (ACDF) group (n=30) underwent 3-level fusion and the HS group (n=19) underwent combined surgery with fusion and CDR. Clinical outcomes were evaluated using the visual analogue scale for the arm, the neck disability index (NDI), Odom criteria and postoperative complications...

INTRODUCTION: The parathyroid gland was first identified in the Indian rhinoceros in 1849 by Sir Richard Owen. We performed a necropsy in an Indian rhinoceros, recapitulating Owen's dissection and display what appear to be the initial identification of the recurrent laryngeal nerve in situ and the anatomy and histology of the largest rhinoceros parathyroid glands yet identified. MATERIALS AND METHODS: Patrick T. Rhino, a 41-year-old Indian rhinoceros was born in 1974...

BACKGROUND: Ossification of the posterior longitudinal ligament or the ligamentum flavum parallels endochondral ossification. Cell differentiation at the ossification front is known to be important during this process, although the factors regulating its initiation and progression are still unclear. The purpose of this study was to identify factors important for the regulation of chondrocyte/osteoblast differentiation during spinal ossification. METHODS: Ligamentum flavum tissue was isolated from 25 patients who underwent decompressive surgery for cervical ossification of the posterior longitudinal ligament...

BACKGROUND The aim of this study was to retrospectively analyze the clinical and radiological efficacy of Bryan cervical artificial disc replacement (ADR) for "skip" multi-segment cervical spondylosis (SCS). MATERIAL AND METHODS We enrolled 49 patients with SCS treated with either Bryan cervical ADR (18 cases) or ACDF (31 cases). Each case was evaluated preoperatively and at more than 48 months postoperatively in follow-up using the JOA, NDI, and VAS. Cervical sagittal curvature, total cervical ROM, and degree of middle segments of motion were also evaluated...

STUDY DESIGN: Clinimetric evaluation study. INTRODUCTION: Despite the availability of numerous performance tests to measure finger dexterity, there is no international consensus on hand function evaluation. PURPOSE OF THE STUDY: To evaluate the reliability, validity, and responsiveness of the modified version of the simple test for evaluating hand function (STEF), which is widely used in Japan. METHODS: The intrarater (n = 40) and inter-rater (n = 32) reliability of the modified STEF was evaluated by calculating the intraclass correlation coefficient (ICC), models (1,1) and (2,1), respectively, in healthy individuals...

Hand weakness and wasting in the setting of mid-cervical spondylosis and disc herniation without radiological evidence for compression of the C8 or T1 roots has been rarely reported. We retrospectively studied the data of patients with hand weakness and mid-cervical spondylosis. The clinical and radiological findings were compared to a control group of patients with weakness of the arm or forearm muscles and similar mid-cervical spondylosis. We found 19 patients with weakness and atrophy of the intrinsic hand muscles, and 13 patients with weakness proximal to the hand muscles to serve as a control group...

Cervical spondylosis and intervertebral disc (IVD) degeneration are the most common cause for compression of the spinal cord and/or its roots. Total IVD arthroplasty, as a modern alternative to surgical treatment of IVD degeneration, is gaining popularity in many neurosurgical clinics around the world. Aim - the study aim was to conduct a multicenter analysis of cervical spine arthroplasty with an IVD prosthesis M6-C ('Spinal Kinetics', USA). MATERIAL AND METHODS: The study included 112 patients (77 males and 35 females)...

OBJECTIVE: To observe the clinical efficacy of modified acupuncture at Renying point (ST 9) for patients with cervical spondylosis of vertebral artery type and its influence on velocity of cervical blood flow. METHODS: Fifty-nine cases of vertebral artery type cervical spondylosis were randomly divided into control group (n=30) and treatment group (n=29). Both groups were acupunctured at ST 9, with routine acupuncture technique used in the control group and modified technique in the treatment group, respectively...

BACKGROUND: The clinical results of surgical spine care may be influenced by the patients' understanding and knowledge of his or her condition, treatment options and decision-making process. The aim of this survey study was to evaluate certain beliefs and opinions of patients with a degenerative condition in the cervical spine with a history of cervical radiculopathy such as importance of magnetic resonance imaging, risk factors, treatment alternatives and effectiveness. METHODS: An anonymous questionnaire survey was performed on two different patient populations with a degenerative condition in the cervical spine with a history of cervical radiculopathy referred to the outpatients' clinics of two neurosurgical departments in Germany and Norway...

Anterior cervical spine procedures have been associated with satisfactory outcomes. However, the occurrence of troublesome complications, although uncommon, needs to be taken into consideration. The purpose of our study was to assess the actual incidence of anterior cervical spine procedure-associated complications and identify any predisposing factors. A total of 114 patients undergoing anterior cervical procedures over a 6-year period were included in our retrospective, case-control study. The diagnosis was cervical radiculopathy, and/or myelopathy due to degenerative disc disease, cervical spondylosis, or traumatic cervical spine injury...

STUDY DESIGN: a retrospective study. OBJECTIVES: Anterior cervical fusion surgery is widely used procedure in cervical spondylosis. When considering the blood re-infusion strategies of cervical fusion surgery, the amount of blood loss is one of the key element. We usually calculate the blood loss according to the surgical bleeding plus the postoperative drainage; however, it ignored the possibility that there may be a partly amount of hidden blood loss. METHODS: We performed a retrospective study to determine the risk factors for HBL in patients underwent anterior cervical fusion surgery for degenerative spine from 2013 to 2016...

Background Disease of the cervical spine is widely prevalent, most commonly secondary to degenerative disc changes and spondylosis. Objective The goal of the paper was to identify a possible discrepancy regarding the length of stay (LOS) between the anterior and posterior approaches to elective cervical spine surgery and identify contributing factors. Methods A retrospective study was performed on 587 patients (341 anterior, 246 posterior) that underwent elective cervical spinal surgery between October 2001 and March 2014...

BACKGROUND: A syrinx is a fluid-filled cavity within the spinal cord. They can lead to a variety of symptoms, including limb weakness and back pain. Incidental finding of syringomyelia provides a challenge for clinicians due to the wide variety of possible symptoms. In military aviation, neurological findings in pilots can result in extensive investigation that can lead to potentially invasive management. Conversely, the potential for chronic progression of a spinal syrinx and subsequent neurological deterioration makes early identification critical...

BACKGROUND CONTEXT: Degenerative cervical myelopathy (DCM) is a progressive degenerative spine disease and the most common cause of spinal cord impairment in adults worldwide. There is a paucity of studies reporting on regional variations in demographics, clinical presentation, disease causation and surgical effectiveness. PURPOSE: To evaluate differences in demographics, causative pathology, management strategies, surgical outcomes, length of hospital stay and complications across four geographic regions...
