Abstract:
Objective To discuss the value of the posterior long segments pedicle screws fixation in surgical treatment of thoracolumbar fracture-dislocation,and summarize the experience.Method s We reviewed the clinical information of 27 cases of thoracolumbar fracture-dislocation since July 2007 to March 2010; all the cases were treated with the posterior long segments pedicle screws fixation.In these cases,20were male,7 were female.And the age ranged from 18 to 58 years old (average age was 35 years).The posterior approach was used,and the pedicle screws were inserted into the 2 vertebrae above and below the fractured vertebrae.Posterior decompression and bone grafts for fusion were also accomplished during the operation.Results Follow-up ranged from 7 to 25 months,averaging 14 months.Completely restoration of the dislocation was got in 25 cases and the spine sequence resumed to nearly normal.One case with lateral dislocation failed to complete correction; another 1 case operated 20 days after surgery failed to complete correction of forward dislocation.At the last follow-up,the mean Cobb angle loss was 3 degrees,the height of the vertebral had obvious loss compared with that of post-operation.The loosen of screw nut was found during the follow-up,but no dislocation and secondary deformity were observed after fixation.There was no death,no infection.Conclusions The technique of posterior long segments pedicle screw fixation is of great value in the clinical applications,since it has the following advantages:the operation is simple,trauma is small,the fixation is firm,good restoration of fracture and dislocations can be easily got,and most importantly,it can effectively prevent long-term vertebral height loss and the backward protruding deformity.
