We evaluate the efficacy and safety of single anterior screw fixation in the treatment of types II and III (Anderson and D'Alonzo classification) odontoid process fractures, and analyse our surgical results. From May 1996 to October 2003, 16 patients underwent single anterior screw fixation for type II (n=12) and III (n=4) odontoid process fractures and had(More)
We present two patients who had acute paraplegia with sensory loss due to spontaneous spinal epidural hematoma (SSEH). One had myocardial infraction and the other had deep vein thrombosis, and the former was treated with anticoagulants and the latter was treated with thrombolytic agent. We analyzed the neurological status of our two cases each between its(More)
STUDY DESIGN Retrospective analysis using positional MRI. OBJECTIVE To determine the effects of total sagittal lordosis on spinal kinematics and degree of disc degeneration in the lumbar spine. SUMMARY OF BACKGROUND DATA Changes in sagittal lordosis alter the load on the spine and may affect spinal mobility. There is increasing recognition of the(More)
This study compared the results of combined anterior and posterior fixation/fusion with those of anterior fixation/fusion alone through a retrospective review of 50 patients with a distraction flexion injury of the cervical spine. Group A (n=28) had unilateral facet joint subluxation or dislocation (Allen stage I or II) and anterior fixation/fusion alone.(More)
Three different surgical methods were used to treat single-segment degenerative cervical spine disease, and the radiological and clinical outcomes were compared. The three groups compared were: 21 cases of anterior interbody fusion with iliac autograft (group A); 20 cases of anterior plate fixation with iliac autograft (group B); and 19 cases of carbon cage(More)
Stem cell research has been attained a greater attention in most fields of medicine due to its potential for many incurable diseases through replacing or helping the regeneration of damaged cells or tissues. Here, we demonstrated the functional recovery and structural connection of the central nervous system pathway innervating the sciatic nerve after total(More)
OBJECT Degenerative changes of the interspinous ligaments (ISLs) have generally been ignored in previous studies. Factor-related causes, the effects that these changes have on other structures within the spinal functional unit, and their relation to kinematic changes in the spine are lacking. In this study, the authors evaluated the reliability of a(More)
BACKGROUND Here we present a case of cervical spinal epidural abscess causing neurologic deficits despite negative serologic tests. CASE DESCRIPTION Unlike a previously reported case, blood cultures and serologic tests were negative for this 50-year-old male with cervical brucellar spondylodiscitis and neurologic deficits. The diagnosis was made based on(More)
Despite that recombinant human bone morphogenetic protein-2 (rhBMP-2) has been reported as a stimulatory effecter of cancer cell growth because of its characteristic like morphogen, the biological functions of rhBMP-2 in human esophageal cancer cells are unknown. The purpose of this study was to investigate whether rhBMP-2 has an inhibitory effect on the(More)
RATIONALE Retrograde drilling is a well accepted procedure for osteochondral lesion of the talus and subchondral cyst with intact overlying cartilage. It has good results in most reports. Compared to anterograde drilling, retrograde drilling can protect the integrity of the articular cartilage. The purpose of this study was to evaluate the suitability of(More)
