Acute neurologic deterioration is not a rare event in the surgical decompression for thoracic spinal stenosis. We report a case of transient paraparesis after decompressive laminectomy in a 50-yr-old male patient with multi-level thoracic ossification of the ligamentum flavum and cervical ossification of the posterior longitudinal ligament. Decompressive laminectomy from T9 to T11 was performed without gross neurological improvement. Two weeks after the first operation, laminoplasty from C4 to C6 and additional decompressive laminectomies of T3, T4, T6, and T8 were performed. Paraparesis developed 3 hr after the second operation, which recovered spontaneously 5 hr thereafter. CT and MRI were immediately performed, but there were no corresponding lesions. Vascular compromise of the borderlines of the arterial supply by microthrombi might be responsible for the paraparesis.

OBJECTIVETo study the etiology and clinical significance of axial symptoms after posterior operative procedures for ossification of the posterior longitudinal ligament (OPLL).
METHODSFrom February 2005 to February 2010, 76 patients with OPLL treated were retrospectively experienced. There were 34 male and 42 female with average of 52.1 years (range from 37 to 74 years), the average duration of the disease was 32.1 months (range from 11 to 56 months). Nineteen patients underwent traditional laminectomy in group A, 33 patients received open-door laminoplasty in group B and 24 patients underwent lateral mass screw fixation in group C. All patients underwent X-ray examination pre- and post operative, computed tomography were used for diagnosis of OPLL, the recovery rate was calculated using pre- and postoperative Japanese Orthopedic Association (JOA) scores for each patient. Pre- and postoperative cervical curvature index and axial symptoms were measured and compared. χ(2) test and SNK test were used as statistical methods.
RESULTSAll patients were followed up for 14 - 35 months, average (21 ± 5) months. Loss of cervical curvature index was 4.2% ± 1.7% in group A, 2.9% ± 2.2% in group B and 2.3% ± 1.9% in group C. The difference was significant in loss of cervical curvature indice between group A and B (q = 2.94, P < 0.01), group A and C (q = 4.23, P < 0.01). The average JOA recovery rate was 58.3% for group A, 64.3% for group B and 66.7% for group C. There was no significant difference in JOA recovery rate among the three groups (P > 0.05). The rate of early evident axial symptoms was 7/19 in group A, 30.3% in group B and 33.3% in group C and the difference was not statistically significant (P > 0.05). The incidence of late evident axial symptoms was 5/19 in group A, 12.1% in group B and 8.3% in group C, the difference was not significant between group B and C (χ(2) = 13.762, P < 0.01), but of statistical difference between group A and B(χ(2) = 6.368, P < 0.01), group A and C (χ(2) = 11.481, P < 0.01). No kyphotic deformity in the group A, no "Close Door" phenomenon in group B and no internal failure in group C.
CONCLUSIONThe incidence of early axial symptoms are of no significant difference among the three groups, but late axial symptoms are higher in the laminectomy than other groups, which may be associated with loss of cervical lordosis.

4.Update on prevention of epidural adhesion after lumbar laminectomy.
China Journal of Orthopaedics and Traumatology 2015;28(11):1064-1068
Postoperative epidural adhesion is one of the most common causes of failed back surgery syndrome (FBSS), which can lead to back and leg pain or neurological deficit. Prevention of epidural adhesion after laminectomy is critical for improving the outcomes of lumbar surgery. The main origins of epidural fibrosis are raw surface of erector muscles and rupture fibers of intervertebral disc. The main current preventive methods for epidural adhesion include the usage of implants, chemicals and low dose radiation. However, most of them are still in experiment period. There are still controversies on the clinic usage of autograft free fat, ADCON-L, and Mitomycin C (MMC). The optimal implants are characteristics of better biocompatibility, degradable absorption and capability of existing for a certain period in body. The optimal medicine should have good effect on anti-desmoplasia, less side effects and long half-life. Besides, the combination of biodegradable medical film and drug and the mixture of two or more medical films are also the research frontlines of epidural adhesion. Further researches are required to explore new materials and drugs with stable and most favorable effect in preventing epidural adhesion.

OBJECTIVETo explore the clinical features, treatment and prognosis of the C5 palsy after surgery of cervical spondylosis.
METHODSTwo hundred and twenty-three cases treated from March 1994 to October 2003 were retrospectively reviewed.
RESULTSSeven of the 223 cases developed the complication of C5 palsy, manifesting the paresis of the deltoid muscle as well as the sensory deficits and (or) intractable pain in shoulder. The incidence was 3.1%. In this study, 2 cases occurred in the anterior subcorpectomy, 5 cases developed in the laminoplasty with 1 case on the opened side, 3 cases on the hinged side and 1 case on both sides. All the 7 cases with the C5 palsy recovered within 2 weeks to 6 months.
CONCLUSIONThe C5 palsy can develop either anterior decompression or posterior open-door laminoplasty of cervical spondylosis. Generally speaking, patients with postoperative C5 palsy can be cured by conservative measures. And prognosis is good.

OBJECTIVETo explore the postoperative complication and its preventive measure of cervical open-door expansive laminoplasty with lateral mass screw fixation in treating cervical canal stenosis.
METHODSFrom February 2008 to July 2011, 33 patients with cervical canal stenosis underwent cervical open-door expansive laminoplasty with lateral mass screw fixation. JOA score was used to evaluate clinical effects before and after operation. Of them, complications occurred in 6 cases, male in 2 cases and female in 4 cases. The reason of complications were analyzed.
RESULTSAll the patients were followed up from 6 months to 2 years with an average of 10.3 months. The improvement rate of JOA was 78.8% and incidence rate of complication was 18.2% (6 cases). There were 2 cases of axiality symptoms, 1 case of lateral mass screw pulled-out, 2 cases of cerebrospinal fluid leakage with wound dehiscence, 1 case of nerve root parlysis. These complications correlated with operative design, manipulation,improved degree of cervical curvature,postoperative management and cooperation of patient.
CONCLUSIONAs an effective treatment, cervical open-door expansive laminoplasty with lateral mass screw fixation has lower incidence of axiality pain. Preoperative examination ,postoperative management ,meticulous surgical skill are very important to avoid complications.

OBJECTIVETo investigate the incidence of C5 nerve root palsy after multi-segmental cervical decompression through different approaches.
METHODSThis study was conducted among 375 patients undergoing multi-segmental cervical decompression in anterior corpectomy and fusion fixation, anterior cervical corpectomy and fusion fixation + posterior decompression and fusion fixation, posterior cervical laminectomy decompression, fusion and internal fixation, and posterior laminoplasty and fusion groups. The exclusion criteria included lack of follow-up data, spinal cord injury preventing preoperative or postoperative motor testing, or surgery not involving the C5 level. The incidence of C5 palsy was determined and the potential risk factors C5 palsy were analyzed including age, sex, revision surgery, preoperative weakness, diabetes, smoking, number of levels decompressed, and a history of previous upper extremity surgery.
RESULTSOf the 375 patients, 60 patients were excluded and the data of 315 patients were analyzed, including 146 women and 169 men with a mean age of 57.7 years (range 39-72 years). The overall incidence of C5 nerve palsy was 6.03% (19/315) in these patients; in the subgroups receiving different surgeries, the incidence was 8.62% in the cervical road laminectomy and fusion fixation group, 7.79% in the anterior cervical corpectomy and fusion fixation + posterior decompression and fusion and internal fixation, 4.68% in the anterior corpectomy and fusion fixation group, and 3.85% in the posterior laminoplasty and fusion group. No significant difference was found in the incidences among the subgroups, but men were more likely than women to develop cervical nerve root palsy (8.28% vs 3.42%, P<0.05).
CONCLUSIONThe overall incidence of C5 nerve palsy following postoperative cervical spinal decompression was 6.03% in our cohort. The incidence of C5 nerve palsy did not differ significantly following different cervical decompression surgeries, but the incidence was the highest in the posterior cervical laminectomy and fusion and internal fixation group.

OBJECTIVESTo study the effects of Sanqi qisodium hyaluronate gel on collagen-I and collagen-III expression in the process of rabbits' epidural scar formation after operation.
METHODSNinety-six white rabbits with 6-month-old, half males and half females, weighted from 2 to 2.5 kg, which were randomly divided into normal saline group (A), Sanqi group (B), qisodium hyaluronate group (C) and Sanqi qisodium hyaluronate gel group (D). The laminectomy of rabbits were performed in group A, B, C, D, the duras were surrounded with normal saline, Sanqi liquid, qisodium hyaluronate and Sanqi qisodium hyaluronate gel respectively. Animals of each group were killed at 1, 2, 4, 8 weeks after operation. Use Masson staining for histological observation of collagen, and in situ hybridization staining for the analysis of collagen-I and collagen-III expression.
RESULTSIn the Masson staining, Sanqi qisodium hyaluronate gel group was more regular than the control group in the shape of collagen texture. As to the expression of collagen-I, and Sanqi qisodium hyaluronate gel group was lower than normal saline group, the Sanqi group and qisodium hyaluronate group at 4 weeks after using medicine (P < 0.01); while the Sanqi qisodium hyaluronate gel group was higher than normal saline group, Sanqi group and qisodium hyaluronate group in the collagen-III expression (P < 0.01).
CONCLUSIONSSanqi qisodium hyaluronate gel could improve collagen's arrangement of the rabbit's epidural scar after operation, reduce its rigidity and increase flexibility.

Transarterial chemoembolization (TACE) is one of the most effective therapies for unresectable hepatocelluar carcinoma or metastatic hypervascular tumors. Abscess occurring in the other organs beside the liver after TACE is a complication that often occurs, sometimes potentially fatal. We report a case of spinal epidural abscess occurred after liver abscess complicated by TACE in a patient with metastatic neuroendocrine tumors to the liver. A 67-year-old female underwent TACE first for the metastatic lesions to liver, with a history of pancreatoduodenectomy for the primary pancreatic neuroendocrine tumor. Four days after TACE, sudden high fever occurred, and liver abscess was found on abdominal CT. Two days later, back pain and radiating pain to the right leg occurred, and lumbar spine MRI showed spinal epidural abscess. After intravenous antibiotics for 8 weeks and partial laminectomy, the patient recovered and was discharged without complications.

10.Visual Loss in One Eye after Spinal Surgery.
Korean Journal of Ophthalmology 2006;20(2):139-142
PURPOSE: To report a patient who developed an unusual combination of central retinal artery occlusion with ophthalmoplegia following spinal surgery in the prone position. METHODS: A 60-year-old man underwent a cervical spinal surgery in the prone position. Soon after recovery he could not open his right eye and had ocular pain due to the general anesthesia. Upon examination, we determined that he had a central retinal artery occlusion with total ophthalmoplegia. RESULTS: Despite medical treatment, optic atrophy was still present at the following examination. Ptosis and the afferent pupillary defect disappeared and ocular motility was recovered, but visual loss persisted until the last follow-up. CONCLUSIONS: A prolonged prone position during spinal surgery can cause external compression of the eye, causing serious and irreversible injury to the orbital structures. Therefore, if the patient shows postoperative signs of orbital swelling after spinal surgery the condition should be immediately evaluated and treated.
