Application Study of Self-made Retractors in Single-door Cervical Canal Enlargement Surgery
Objective To explore the clinical effectiveness of self-made retractors in assisting with posterior cervical single-door laminoplasty for the treatment of cervical spondylotic myelopathy(CSM).Methods A retrospective analysis was conducted on the clinical data of 60 patients diagnosed with CSM from July 2016 to September 2022 at Henan Orthopedic Hospital.There were 34 males and 26 females,aged 32 to 81 years,with an average age of(57.35±10.77)years;the course of the disease ranged from 6 to 42 months,with an average of(15.95±7.16)months.Patients were divided into two groups,A and B,based on whether self-made retractors were used during surgery.Group A(30 cases)underwent posterior cervical single-door canal enlargement surgery with the assistance of self-made retractors;Group B(30 cases)underwent the same surgery with conventional instruments such as bone levers and laminar hooks.The age,disease course,operation time,intraoperative blood loss,postoperative complications,and Japanese orthopaedic association(JOA)scores and visual analogue scale(VAS)scores at preoperative,3 months postoperative,6 months postoperative,and 12 months postoperative were compared between the two groups,as well as the rate of excellent and good JO A scores at the last follow-up.Results All patients were followed up,with a follow-up time ranging from 14 to 18 months,and an average follow-up of(16.40±2.31)months.There were no statistically significant differences in disease course,age,and postoperative complications between the two groups(P＞0.05);Group A had shorter operation times and less blood loss than Group B(P＜0.05).Both groups showed significant improvements in JOA scores and VAS postoperatively compared to preoperatively(P＜0.05),with Group A showing better VAS and JOA scores at 3 months,6 months,and 12 months postoperatively than Group B(P＜0.05),and a higher rate of excellent and good outcomes than Group B.Conclusion The use of self-made retractors in posterior single-door surgery for CSM can shorten operation times,reduce intraoperative blood loss,alleviate postoperative neck and shoulder pain,result in smaller surgical incisions,and promote postoperative neurological recovery in patients,effectively accelerating postoperative rehabilitation and is worth promoting in clinical practice.
