Abstract:
OBJECTIVETo observe the curative effects and complications of Bryan cervical disc replacement for cervical disc herniation.
METHODSFrom Jannary 2005 to December 2008,39 patients with cervical disc herniation were treated with Bryan cervical disc replacement. There were 20 males and 19 females,with an average age of 47 years old (ranged, 35 to 59). Spinal compression symptom (20 cases) and nerve root symptom (19 cases) were main clinical symptoms. Single level disc was replaced in 35 cases and two-level replaced in 4 cases. Offset and activity of prosthesis,cervical physiological curvature, heterotopic ossification, prosthetic fusion were observed by dynamic X-ray. According to Odom's standard and JOA score,nerve function were evaluated; and depending on NDI standard,clinical symptom and daily function status were recorded.
RESULTSAll the patients were followed up from 16 to 36 months with an average of 24 months. Nerve function obviously improved and radiating pain of upper limb completely relieved. No patient with prosthetic anterior-posterior offset more than 2 mm was found. Prosthetic flexion and extention angle was (8.5+-1.8)degrees,left and right flexion range respectively were (3.5+/-1.2)degrees and (3.3+/-1.5)degrees. Cervical physiological curvature improved obviously or recovered normally. Three cases occurred in heterotopic ossification and 2 cases occurred in prosthetic fusion. According to Odom's standard,25 cases got an excellent results,9 good, 5 fair, the rate of excellent and good was 87.2%. JOA score increased from preoperative (8.26+/-1.32) to (15.71+/-1.89) at final follow-up and NDI decreased from preoperative (43.7+/-3.8) to (20.1+/-2.9) at final follow-up.
CONCLUSIONTreatment of cervical disc herniation with Bryan cervical disc replacement can get the good curative effects,which can obtain good nerve functional recovery,cervical stability and activity. Nevertheless,the operation has typical complication such as heterotopic ossification and prosthetic fusion. Thus,it is important in chosing indication and operative procedure.
