ABSTRACT

Objective To study cerebral cortical activation preoperatively and postoperatively in patients with cervical spondylotic myelopathy (CSM), and discuss effect of the surgery on cortical reorganization in functional recovery.Methods 19 cases with CSM intrial group underwent cervical vertebra canal decompression surgery according to clinical routine.Cases in trial group completed clinical assessment using the modified Japanese Orthopaedic Association Scores (mJOA) prior to decompression and 12 months following surgery, and underwent cerebral functional MRI and conventional MRI in the same time.19 controls also carried out cerebral functional MRI and conventional MRI.All subjects performed a finger-tapping paradigm with right hand during processing functional MRI.The imagings and data of trial group were divided into preoperative group and postoperative group in accordance with the time of completed and than analysed.Results The mJOA score of postoperative group was increased significantly (P<0.001).Cortical volume of activation (VOA) of preoperative group was significantly higher than the control group (P<0.05).VOA was lower in the postoperative group, but still significantly higher than the control group (P<0.05).The preoperative group was able to detect and activate the signal only in the left precentral gyrus.The postoperative group was able to detect and activate the signal in the l left postcentral gyrus, the premotor area and the supplementary motor area, and the right cerebral cortex could also detect a small amount of activation signal.Conclusion CSM patients undergo cerebral cortical remodeling, causing sensory and motor function activation areas to expand and shift.The changes of cortical reorganization after cervical vertebra canal decompression surgery are associated with functional recovery.The surgical treatment may promote the compensating cortical reorganization.

ABSTRACT

Objective To investigate incision pathogenic bacteria after spinal surgery, and observe clinical effects of therapeutic methods. Methods A total of 30 cases of early surgical incision infection (7 cases of superficial infection and 23 cases of deep infection) after spinal surgery were retrospectively analyzed. The basic data including clinical manifes-tations, diagnosis, treatment, etiology and follow-up results were analyzed. Results It was found that the mean infection time after operation was 2-15 days in 30 patients. Thirty-three strains were isolated including 18 gram-positive cocci (54.5%, and Staphylococcus aureus account for 13, 39.4%), 15 gram-negative bacteria (45.5%, and Coli communior account for 6, 18.2%). The drug susceptibility test showed that gram-positive cocci were highly sensitive to vancomycin, rifampin, tei-coplanin and cotrimoxazole. No vancomycin-resistant Staphylococcus aureus were found. Gram negative bacteria were high-ly sensitive to imipenem (100%). Seven cases of superficial infection were cured after dressing. Twenty-three cases of deep incision wound infection were no recurrence of infection after treatment by deep wound debridement, and postoperative cathe-terization. Conclusion The early wound infection after spinal surgery is usually due to Staphylococcus aureus. It is good to perform wound debridement, continuous perfusion drainage, and treatment with vancomycin for deep wound infection.
