Chordomas are low-grade, locally invasive, frequently recurring, malignant bone tumor with poor prognosis. Cervical chordoma in adults is rare and often missed when patients present cervical radiculopathy. They can mimic other tumors and, hence require histologic distinction for prognostic risk stratification optimal treatment. We a 61-year-old male chronic neck pain sensory neuropathy bilatera...

This was a prospective comparative study.The aim of this study was to compare the clinical and radiologic outcomes of patients treated with cortico/cancellous composite allograft or autoiliac bone graft in anterior cervical discectomy and fusion.Several methods have been developed to fuse the cervical spine for treatment of cervical spondylosis. Cortico/cancellous composite allograft might be a...

BACKGROUND Surgical intervention is increasingly performed as the primary treatment of unstable Hangman's fracture. Some authors have advocated using anterior C2/3 discectomy with interbody fusion and plating to treat unstable Hangman's fracture combined with intervertebral disc injury; however, there are few reports on unstable Hangman's fracture treated by anterior interbody fusion with the c...

RATIONALE Artificial cervical disc replacement (ACDR) has been reported to be an effective and safe surgical treatment for cervical spondylosis. However, iatrogenic fracture during ACDR surgery has rarely been reported. Considering its infrequency, we report a rare clinical case, with the aim of sharing our experience and exploring when to convert ACDR to fusion intraoperatively. PATIENTS CON...

Background: Endoscopic Cervical Discectomy has replaced many open fusion related surgery and bone grafting. Endoscopic surgery is without the placement of retractor and only need a working sheath diameter of about 7 mm incision, which is simple, easy to access with proper visualization. Minimal invasive surgery helped advancement in surgery by improvement in visualization. Depend on extend of l...

BACKGROUND Cervical radiculopathy is the common clinical entity, often caused by "wear and tear" changes that occur in the spine. In the younger population, cervical radiculopathy is a result of a disc herniation or an acute injury causing foraminal impingement of an exiting nerve, whereas in the older individuals, it is due to foraminal narrowing from osteophyte formation, decreased disc heigh...

This study intended to investigate the safety and efficacy of microendoscopic discectomy system compared with anterior open approach in the treatment of odontoid fracture with cannulated screw internal fiation. Thirty-two patients (25 male and 7 female) were enrolled and randomly assigned to different treatments. 15 patients were treated with microendoscopic discectomy system (Group MED) and 17...

OBJECTIVE It remains debatable whether cervical spine fusion cages should be filled with any kind of bone or bone substitute. Cortical and subcortical bone from the anterior and posterior osteophytes of the segment could be used to fill the cage. The purposes of the present study are to evaluate the clinical outcomes and radiological outcomes including bone fusion and subsidence that occurred a...

introduction sub axial cervical spine dislocations are common and managing these cases by closed reduction is successful in the majority of cases. however, treatment of old and neglected cases is difficult and the results may vary in terms of neurological and functional outcomes. case presentation we present two cases of traumatic bilateral cervical facet dislocation with no neurological defici...
