Clinical analysis of surgical reconstitution of cervicothoracic junction / 中华骨科杂志

ABSTRACT

ObjectiveTo discuss the selection of surgical approach,operative methods,and stability of reconstitution of affection of cervicothoracic junction.MethodsFrom January 2001 to February 2009,86cases with affection of cervicothoracic junction were treated surgically.The mean age of patients at the time of surgery was 43.1 years (range,17-70).Fifty-seven patients were treated with anterior approach (fixation with autologous bone grafts was done in 38 patients,Cage fixation in 5,titanium mesh in 14),21 with posterior approach(the fixation of lateral mass screw combined with pedicle screw was used in 12 patients,fixation with pedicle screw in 9),and 8 with anterior combined posterior approach.The neurological function of 53 cases of injury of cervicothoracic junction was assessed by American Spinal Injury Association (ASIA) criteria,and the rest was assessed by Japanese Orthopaedic Association(JOA) criteria; bone arthrodesis and restoring lordosis of cervical spine were assessed by Bohlman radiographic criteria.ResultsSixty-nine cases were followed up for an average of 12.4 months(range,3-45).ASIA score increased from 1.8 preoperatively to 2.3 postoperatively,and JOA score increased from 10.3 preoperatively to 12.8 postoperatively.Bone fusion reached in all patients,and lordosis of the cervical spine of 62 cases was restored.One case with respiratory dysfunction,1 case with cerebrospinal fluid leakage,2 cases with hoarseness,and 1 case with loose lateral mass screw were found after the surgery.ConclusionThe advantages of surgical reconstitution of the cervicothoracic junction included promoting recovery of neurological function,restoring the alignment and lordosis of the cervical spine,decreasing the rate of complication,which were dependent on the suitable surgical indications,surgical approach,and way of surgical reconstitution.The selection of reconstituted methods depends on disease,lesion site,type and degree of injury,experience of doctor,decompression and spinal stabilization synthetically.
