ABSTRACT
Objective To investigate the clinical effect of pedicle screw fixation in the treatment of fracture and dislocation of atlantoaxial spine via posterior approach .Methods 19 patients with fracture and dislocation of atlantoaxial spine in this hospital from June 2011 to December 2013 were selected and treated with open reduction and pedicle screw fixation via posterior approach . The X‐radiographs were postoperatively re‐examined at regular time for understanding the correction of fracture and dislocation and implant fusion results ,the neurological functions were evaluated according to the Japanese Orthopaedic Association(JOA) scores . Results All cases got bony fusion without the occurrence of internal fixation loosening ,broken screw or broken rod .The JOA score was improved from preoperative (7 .35 ± 2 .39) points to postoperative (13 .21 ± 2 .53) points (P<0 .05) .Conclusion The posteri‐or atlantoaxial pedicle screw fixation and fusion for treating upper cervical spine injury has satisfactory effect .
ABSTRACT
BACKGROUND:At present, percutaneous vertebroplasty has been widely used in clinical treatment of osteoporotic vertebral fractures. Considering the limitations of the underlying disease in elderly patients (> 65 years of age) at surgery, the relevant detailed studies have gradualy attracted the attention of clinicians. OBJECTIVE:To compare and analyze the clinical effects of vertebroplasty with bone cement and conventional fracture reduction for elderly osteoporotic thoracolumbar fractures. METHODS:Totaly 24 elderly patients with osteoporotic thoracolumbar fractures were voluntarily divided into bone cement treatment and conservative treatment groups (n=12 per group) and subjected to vertebroplasty with polymethylmethacrylate bone cement and conventional reduction therapy, respectively. RESULTS AND CONCLUSION:Compared with the conservative treatment group, the visual analog scale scores, Oswesty dysfunction index and Cobb angle were significantly reduced in the bone cement treatment group, while the degree of anterior vertebral compression was increased. These results suggest that minimaly invasive spine treatment is conducive to improve the fracture healing and enhance the quality of life in elderly patients with osteoporotic vertebral compression fractures in stable conditions.
