Re-evaluation of the effect of autologous fibula plate in treatment of old nonunion of long bone fracture / 中国矫形外科杂志

[Objective]To discuss the technique and outcome in the treatment of old nonunion of long bone fracture by using autologous fibula plate alone or combination with internal fixator plates.[Method]Fifty-seven patients(41 males and 16 females;average age of 41.6 years)with nonunion of long bone fracture were recruited.Of them 18 had short deformity(average 2.6 cm)and 12 had angled deformity(average 15?).Average time was 12 months(6-36 months).The sclerosed cortex was removed at both ends of the nonunion long bone.A suitable length of fibula plate were transplanted by screw with or without internal fixator plates.[Result]The follow-up average time was 3 years(ranged,1 to 6 years).At 1,3,6,12,24 months after operation,the outcome was analyzed by radiography.Bone healing was found in all 57 patients,with an average of 15 weeks(8-24 weeks).All the patients exhibited a good function in walking and burdening.No nonunion occurred.[Conclusion]Autologous fibula plate with or without internal fixator plates for nonunion of long bone fracture can facilitate healing and early functional recovery.This therapeutic method is an ideal technique in treating patients with nonunion of long bone fracture.

Introduction of a new invented spondylolisthesis reduction system for treatment of lumbar spondylolisthesis / 中国矫形外科杂志

[Objective]To assess the effect of a new invented spondylolisthesis reduction system:elevating-pull reduction system for surgical treatment of lumbar spinal spondylolisthesis associated with isthmic spondylolysis.[Method]Sixty-two patients with lumbar spinal spondylolisthesis were treated with elevating-pull reduction system combined with SRS(spondylolisthesis reduction system),after surgery the patients were evaluated for symptom improvement,intervertebral bone graft fusion,and internal fixation.[Result]The patients were followed up from 1 to 6 years(average 2 years and 5 months) in 62 patients.According to the criterion,excellent results were in 43 patients,good in 16,moderate in 3.No patient showed worse.No internal fixation loosening and breakage were found.[Conclusion]The new invented spondylolisthesis elevating-pull reduction system combined with SRS are more effective and reliable,especially for those osteoporosis patients and serious cases,the reduction and fixation are more effectively.In this procedure the pedicle entrance mouth can be seen straightly and the pedicle screw is inserted more easily.It can prevent the nerve injury,save the operation time,reduce the blood lossing,and excellent outcome can be obtained.
