    ABSTRACT: To explore the outcomes of longitudinal spinous splitting laminoplasty with coral bone (abbreviated as SLAC) for cervical stenosis. A total of 142 patients underwent conventional SLAC while 147 other patients modified SLAC. Assessments were made at pre-operation, post-operation and 3-month follow-up to examine the effects of two surgical approaches on the recovery rate of JOA (Japanese Orthopedic Association) score. The change of cervical alignment, change of cervical motions, axial syndrome, operative duration and intra-operative blood loss were recorded and analyzed with SPSS 13.0. No significant difference existed between two groups in the recovery rate of JOA score and intra-operative blood loss. The smaller change of cervical alignment and change of cervical motions were found in the modified SLAC group. The modified SLAC group had fewer patients with axial syndrome during the follow-up period. The operative duration was shorter in the modified SLAC group. Preventing muscle injuries in cervical laminoplasty can reduce the incidence of complications. The modified SLAC approach may protect cervical posterior extensor musculature, maintain the cervical lordotic alignment and reduce the incidence of post-operative axial syndrome.

    ABSTRACT: To assess the effect of modified cervical expansive open-door laminoplasty preserving the posterior extensor musculature inserted into the C2 and C7 spinous process upon maintaining the cervical lordotic alignment and axial syndrome and to determine whether preserving the posterior extensor musculature inserted into C2 and C7 spinous process can reduce the complications. Twenty-eight patients undergoing modified cervical expansive open-door laminoplasty preserving the posterior extensor musculature inserted into the C2 and C7 spinous process and 21 patients undergoing conventional C3-C7 cervical expansive open-door laminoplasty were investigated in pre-operative, post-operative and 3-month follow-up. The investigators assessed the effects of two different cervical laminoplasty types in the recovery rate of JOA score, the changes of Cobb angle and Ishihara's index, axial syndrome, operating duration and intra-operative blood loss, analyzed the results in SPSS and tried to find the difference in two operative types. There were the same results in the recovery rate of JOA score and intra-operative blood loss in modified expansive open-door cervical laminoplasty group and the conventional C3-C7 cervical expansive open-door laminoplasty group. The smaller changes of Cobb angle and Ishihara's index in the follow-up of modified laminoplasty group were found. The modified laminoplasty group had fewer patients suffering the axial syndrome in follow-up. The operating duration was shorter in the modified laminoplasty group. Preventing muscle injuries in cervical laminoplasty can reduce the incidence of complications. The modified expansive open-door cervical laminoplasty preserving the posterior extensor musculature inserted into C2 and C7 spinous process can protect cervical posterior extensor musculature. This is helpful to maintain the cervical lordotic alignment and reduce the incidence of post-operative axial syndrome.

    ABSTRACT: To study the short-term clinical outcome of transforaminal lumbar interbody fusion (TLIF) by minimally invasive approach in the treatment of simple foraminal stenosis (SFS). Thirty four cases (M: F = 19: 15) diagnosed with SFS from January. 2007 to March. 2009 were included. Age ranged from 47 to 62 (mean: 57) years old. Patients generally had degenerative changes and decreased disc height on X-ray films at the indexed level. No stenosis within the spinal canal was found on myelograph and CTM. Sagittal images of MRI usually demonstrated narrowed foramina. Selective radiculograph and radicular blocking was used to make the definite diagnosis and to locate the involved nerve root. Double paramedian intermuscular approaches were adopted in all cases. Minimally invasive retractor systems, such as X-Tube and Pipeline etc., were used to facilitate the exposure, pedicle screw instrumentation and TLIF. The average operation time was 2.76 hours. The average blood loss was 387.16 ml. All patients were encouraged to ambulate 2-3 days post-operation. The incisions healed uneventfully. At the final follow-up, instrumentations were maintained in an excellent position in all cases and JOA score improved by 31.14%. TLIF by minimally invasive approach is an effective method in treating patients with lumbar foraminal stenosis. The short-term clinical outcomes are satisfactory. This approach may avoid the injuries to paraspinal muscles, posterior ligaments, dura and nerve root of the uninvolved side.
