The operation is to remove part of vertebral lamina and release the pressure on the spinal nerve. Because many important vessels and nerves are under the vertebral lamina, any incorrect operation may cause irreparable damage to patients. To improve the safety of lamina milling task, a fuzzy force control strategy is proposed in this paper. Primary experiments have been conducted on bone samples from different animals. The results show that, with the fuzzy force control strategy, the bone milling system can recognize all surgery states and halt the tool at the proper location, achieving satisfactory surgery performance.展开更多

Methods： 24 patients who underwent operations between September 2002 and November 2003 were evaluated for curve correction, spinal balance, and complications. Age at surgery averaged 13.8 years （range from 10 to 20）. The spinal deformities were evaluated by Cobb method with anteroposterior and lateral bending radiographs. All patients were right thoracic curves. Posterior instrumentation （Moss-Miami transpedicular system） was used. The transpedicular screws were placed between T2 and L2. All the patients were assessed both clinically and radiographically. Follow-up averaged 2.8 years. Results： There was an average correction of 72% of the primary curve （pre-operation standing average 54 degrees （range from 40 to 67 degrees）, post-operation average 15.2 degrees （range from 2 to 27 degrees）, at last examination average 16.1 degrees （range from 2 to 30 degrees）. Infection and neurological complications were not noted. No major complications were observed. Conclusions： Frontal and sagittal thoracic curve correction of thoracic scoliosis can be satisfactorily obtained using Moss Miami transpedicular instrumentation. It seems that control of the three columns of the spine by the transpedicular screws offers sufficient apical translation and coronal realignment.展开更多
