Zero-P and ROI-C implants versus traditional titanium plate with cage to treat cervical spondylotic myelopathy: clinical and radiological results with 5 years of follow-up.

Background: Anterior cervical discectomy and fusion (ACDF) is the gold standard for treating cervical spondylotic myelopathy (CSM). While implanting plates in ACDF may increase the risk of complications. Zero-P and ROI-C implants have been gradually applied for CSM.

Clinical application of the anterior pelvic wall locking plate (APWLP) in acetabular fractures involving the quadrilateral surface.

Background: The management of acetabular quadrilateral surface fractures remains challenging for surgeons, and the treatment options for such fractures remain controversial. Quadrilateral surface surgery is a complex procedure involving combined approaches, and the quality of fracture reduction closely depends upon the surgical procedure, as well as the skill and experience of the surgeon. This study aimed to explore the clinical effects of applying an anterior pelvic wall locking plate (APWLP) through the lateral-rectus approach for treating acetabular fractures involving the quadrilateral surface.

Hydrogen sulfide protects against particle-induced inflammatory response and osteolysis via SIRT1 pathway in prosthesis loosening.

Wear debris-induced osteolysis and ensuing aseptic loosening is the main cause of implant failure and revision surgery. Wear debris-induced inflammatory response plays key roles in peri-implant osteolysis. Recently, substantial of evidence suggests that hydrogen sulfide (H S), the third gasotransmitter, is a critical player regulating inflammation.

Analysis of C5 palsy in cervical myelopathy with massive anterior compression following laminoplasty.

Background: Little data is available about comparison of the incidence and clinical characteristics of the C5 palsy between patients of cervical myelopathy with occupying ratio greater than 50% and those with occupying ratio less than 50% following laminoplasty.

Methods: One-hundred eighteen patients with cervical myelopathy who underwent open door laminoplasty were reviewed in this study. The patients were divided into two groups: group A comprising 55 patients with an anterior occupying ratio greater than 50% and group B comprising 63 patients with an anterior occupying less than 50%.

Zero-profile implant (Zero-p) versus plate cage benezech implant (PCB) in the treatment of single-level cervical spondylotic myelopathy.

Background: Anterior cervical discectomy and fusion is the golden standard for anterior surgery treating elderly cervical degenerative disease, but the previous implant has some problems such as looseness, translocation, sinking and dysphagia, So Zero-p implant and PCB implant have been developed to decrease the complications.

Methods: The clinical data of 57 patients with single level cervical spondylotic myelopathy were retrospectively analyzed. 27 patients adopting Zero-p interbody fusion cage as implant (Zero-p group) and 30 patients adopting integrated plate cage benezech (PCB) as implant (PCB group) from January 2010 to October 2012.

Comparisons of three anterior cervical surgeries in treating cervical spondylotic myelopathy.

Background: Anterior cervical discectomy and fusion (ACDF) was one of the preferred treatments for degenerative cervical spondylosis. However, the motion of adjacent segment was significantly increased after operation. So cervical disc arthroplasty have been suggested to keep the motion of adjacent segment.

Effect of occipitocervical fusion with screw-rod system for upper cervical spine tumor.

Background: Craniospinal junction tumors are rare but severe lesions. Surgical stabilization has been established to be an ideal treatment for upper cervical tumor pathology. The purpose of this study was to evaluate the effect of a screw-rod system for occipitocervical fusion.

Impact and clinical significance of pedicle length on spinal canal and intervertebral foramen area.

The aim of this study was to measure changes in the cross-sectional area of the spinal canal and the area of the intervertebral foramen for each pedicle segment before and after the pedicle extension using computer-simulated transpedicular osteotomy to provide a theoretical basis for clinical decompression in the lumbar spinal canal. Using spiral CT scanning of the original lumbar spine, a finite element model was established. The pedicle was cut and extended by 2 mm, 4 mm, 6 mm, and 8 mm for respective modeling.

The application of a zero-profile implant in anterior cervical discectomy and fusion.

We analyzed the clinical efficacy of the Zero-P implant (Synthes GmbH Switzerland, Oberdorf, Switzerland) in the treatment of single level cervical spondylotic myelopathy. The clinical data of 47 patients with single level cervical spondylotic myelopathy were retrospectively analyzed. Twenty-two patients were treated with a Zero-P implant (Group A) and 25 with a titanium plate with cage (Group B) between January 2009 and September 2010.

Comparison of the mini-midvastus with the mini-medial parapatellar approach in primary TKA.

A prospective randomized study was performed to compare the clinical and radiological results of primary total knee arthroplasties (TKAs) using a mini-midvastus approach or a mini-medial parapatellar approach in 134 patients. The mini-midvastus approach was used on 68 patients (group A) and the mini-medial parapatellar approach on 66 patients (group B). All knees were implanted with the same posterior-stabilized prosthesis by the same surgeon (T.

Risk factors for postoperative wound infections of sacral chordoma after surgical excision.

Study Design: A retrospective study, analyzing the risk factors for postoperative wound infections of the sacral chordoma after surgical excision.

Objective: To determine the preoperative, intraoperative, and patient characteristics that contribute to an increased risk of postoperative wound infection in patients undergoing sacral chordoma resection.

Summary Of Background Data: Postoperative wound infection after spinal operations is a dreaded complication.

Management of fracture-dislocation of the lower cervical spine with the cervical pedicle screw system.

Introduction: Usually, cervical pedicle screw fixation has been considered too risky for neurovascular structures. The purpose of this study was to investigate the method and efficacy of the cervical pedicle screw system for fracture-dislocation of the cervical spine because of its rigid fixation.

Patients And Methods: A prospective study was conducted involving 48 patients with cervical spine fracture-dislocation who underwent cervical pedicle screw fixation surgery between January 2003 and January 2007.

CT evaluation of cervical pedicle in a Chinese population for surgical application of transpedicular screw placement.

The lower cervical pedicle size differs between the Chinese and the non-Chinese population. Knowledge of pedicle dimensions and surface landmarks is crucial for the safe placement of screws, but few quantitative data concerning the lower cervical pedicle using CT scan and multiplanar reformations (MPR) in a Chinese population exist. The aim of this study was to evaluate lower cervical pedicle (C3-C7) dimensions in a Chinese population by computed axial tomography for surgical application.
