Abstract:
Objective To investigate complications associated with Coflex interspinous process device for degenerative lumbar disc diseases and methods to treat.Methods Clinical data of 121 patients with degenerative lumbar disc diseases,who had undergone surgical decompression and additional fixation of Coflex between November 2007 and June 2011,was analyzed retrospectively.There were 76 males and 45 females,aged from 37 to 75 years (average,54.6 years).Surgery-related complications and sequelae were recorded and analyzed.Results Surgery-related complications occurred in 10 patients,and the incidence was 8.3％ (10/121).There were 3 cases of device-related complications,including wing break in 1 case,prosthetic loosening in 1 case and spinal process fracture in 1 case; all 3 cases were treated conservatively and received good results.There were 7 cases of non-device-related complications,including dura mater dilaceration in 2 cases,superficial wound infection in 1 case,insufficient decompression of spinal canal in 2 cases,recurrence of disc herniation in 1 case,and intraspinal hematoma in 1 case; the former 3 patients recovered after corresponding treatment,and the latter 4 patients also recovered after re-operation.Conclusion The incidences of complications and re-operation associated with application of Coflex are low,and the incidence of device-related complications is also low.The precise intraoperative manipulation is the key to reduce incidence of device-related complications.It's absolutely necessary to strictly master surgical indications and perform sufficient decompression in order to receive good surgical results and avoid non-device-related complications.
