The Surgery Clinical Research Of Scoliosis Associated Syringomyelia Without Neurosis

Objective: 1.To investigate the feasibility of treatment aboutscoliosis associated syringomyelia without neurosis by simple correctionand no surgery intervention to syrinx. 2.To investigate the turnover ofthe syrinx, and whether the syrinx affect correction rate and correctionloss.Methods: Experimental group (group A): Retrospectivelysummarized 15 scoliosis patients associated syringomyelia withoutneurosis, which treated by correction and no surgery intervention tosyrinx. The 15 patients were. measured the preoperative,postoperativeand follow-up coronal plane Cobb angles, measured the length, theposition and the biggest diameter of syrinx and S/C ratio. Controlgroup(group B): 20 AIS patients, whom were operated by the samedoctor with correction in the same time, were selected. Analyzed theclinical characteristic of two group. Compared the onset age, curve shape,coronal correction rate and loss. Analyzed the correlation of scoliosis andsyrinx. Compared the length and biggest diameter of syrinx and S/C ratio.Results: 1.Compared with B group, A group's onset age wasSignificantly smaller than B group (P＜0.01); and the curve shape ismainly left scoliosis; there were no significant differences in thecorrection rate and loss rate; 2. Pearson's correlation showed a significant positive association between the length of syrinx and the biggest diameterof syrinx (P＜0.05), while no significant association was found amongthe length, size and position of syrinx and the position and curve length ofscoliosis (P＞0.05). 3. The follow-up syrinx index of A groupcompared with preoperative syrinx index: there was no significantdifferences in the position of biggest syrinx diameter and the corddiameter (P＞0.05), while the biggest diameter, syrinx length and S/Cratio were significantly smaller than preoperation (P＜0.05).Conclusions: 1. After correction, the syrinx of scoliosis associatedsyringomyelia patients may diminish and be absorbed automaticly, and itwon't aggravate the scoliosis lead to more angle loss. 2. The operatormaybe scruple to syrinx when correction, but the syrinx won't affect thecorrcetion rate. As long as the methods are expedient and avoid draggingspinal cord, the scoliosis patients associated syringomyelia withoutneurosis can just do correction and no sugery intervention to syrinx.3.Scoliosis associated syringomyelia, which usually occurs in male lessthan 10 years, often associated pains and nervous lesion sign and haveleft curve. And the size and position of syrinx have no corelation withcurve length and position.
