Objective To investigate the technique and clinical effects of pedicle screw fixation in treatment of unstable Hangman' s fractures in comparison with the conservative managements. Methods From January 1999 to July 2005, 36 patients with unstable Hangman' s fractures were treated in our department. Based on Levine- Edwards classification, 15 of them were treated with skull traction, and others with internal fixation with posterior pedicle screws (C2,3 fusion in 10 cases and C2- 4 fusion in 11 cases). After a posterior midline incision and clear exposure of posterior structure, the C2 screw was inserted through the center of the posterior aspect of lateral mass, inclining usually 20? to 30? towards the head of the transverse plane and 25? to 35? inwards to the medial incline of the sagittal plane. For C3,C4 screw insertion, the drilling was parallel to the joint plane of the relevant vertebra and inclined 35? to 40? outwards to the medial incline of the sagittal plane. The whole procedure was performed under the monitoring of C- arm screen for safety and accuracy. Results A mean follow- up time was 18 months (5 to 28 months). 6 cases treated by skull traction lost their anatomic reduction. Of the 21 cases treated by the pedicle screw fixation, 2 had loosened internal fixation but 19 experienced no screw loosening and their fractures were cured entirely without limited function of the cervical vertebra. Conclusions In treatment of unstable Hangman' s fractures, C2,3 or C2- 4 pedicle screw fixation is an effective method to achieve rigid reduction and early rehabilitation. However, there is no remarkable difference between C2,3 fusion and C2- 4 fusion

Objective To verify whether the modified open-door laminoplasty with C3 laminectomy is effectve in preventing postoperative axial symptom. Methods Since March 2001 to March 2005, 44 patients who underwent modified open-door laminoplasty with semispinalis cervicis insertion intact were included in this study(group A). 50 patients who underwent conventional open-door laminoplasty in the authors' department during the same period were served as control(group B). Preoperative and postoperative Japanese Orthopedic Association(JOA) scores, the degree of axial symptom, ranges of neck motion, cervical curvature index were recorded and compared. Results The average JOA recovery rate was 59.2%?11.3% for group A and 60.1%?19.5% for group B. There was no significant difference in JOA recovery rate between two groups. The rate of patients with evident axial symptoms was 22.7% in group A and 54.0% in group B, and the difference was statistically significant(P

Objective To investigate the results of early decompression and internal fixation for lower cervical vertebral degenerative instability. Methods Eighty-two patients of low cervical vertebral degenerative instability were reviewed. The patients comprised of 51 males and 31 females, with an average age of 54.3 years. There were 13 patients with neck and shoulder pain, 28 with cervical spondylotic radiculopathy (CSR), 25 with cervical spondylotic myelopathy (CSM), 16 with combined CSR and CSM. Magnetic resonance imaging(MRI) showed that the cervical spinal cords were compressed. All patients had cervical vertebral angular displacement (AD) exceeding 10? or horizontal displacement(HD) surpassing 3 mm at the same level on hyperflexion/hyperextension X-ray films. According to the course of cervical degenerative instability and Kirkaldy-Willis criterion, all patients were diagnosed as cervical vertebral degenerative instability, and recieved anterior decompression, bone grafting and internal fixation. Results All the patients were followed for 9 to 30 months (average 15.4 months). All fused segments achieved bony union. 1) JOA score of 25 cases with CSM and 16 cases with CSR and CSM was 9.52?1.93 before operation and 14.74?3.10 post operation respectively. There was significant statistical difference (P
