ABSTRACT
Methods@#Thirty-one patients with multilevel cervical spondylotic myelopathy who required C6–C7 level decompression surgery were operated and followed up for 24 months. One group (15 patients) received C7 arcocristectomy without laminoplasty, and the other group (16 patients) received C7 laminoplasty. Flexion, neutral, and extension angles were measured using the Cobb method at C2–C7 to evaluate preoperative and postoperative radiographic parameters. Range of motion (ROM), ROM preservation rate of the cervical spine, C2–C7 sagittal vertical axis (SVA), and T1 slope were measured using C-spine lateral X-ray. The Visual Analog Scale (VAS) and modified Japanese Orthopedic Association (JOA) score were used to compare preoperative and postoperative clinical symptoms. @*Results@#Flexion, neutral, extension angles of the cervical spine, C2–C7 SVA, T1 slope, ROM, ROM preservation rate, and modified JOA score were not significantly different between the two groups (p>0.05). In the C7 arcocristectomy group, the average postoperative VAS for axial neck pain was increased in 13.3% (2/15) of the patients, whereas in the C7 laminoplasty group, the average postoperative VAS was increased in 43.8% (7/16) of the patients (p=0.018). @*Conclusions@#C7 arcocristectomy, which preserves the C7 spinous process and posterior structures, is a useful technique for relieving axial neck pain.
ABSTRACT
Purpose@#This study analyzed the effectiveness of arthroscopic anterior compartment debridement with posterior mini-open debridement in patients with mild or moderate primary elbow osteoarthritis (OA). The clinical results of arthroscopic anterior compartment debridement with posterior mini-open debridement were compared with that of arthroscopic both compartments debridement. @*Materials and Methods@#Between January 2010 and December 2016, 46 patients diagnosed with elbow OA underwent arthroscopic anterior compartment debridement with posterior mini-open debridement or arthroscopic anterior and posterior compartments debridement arthroscopic surgery. Of these, 27 patients were finally included in this study. The data were collected retrospectively from the medical records. The subjects were divided into two groups according to the surgical procedure: group 1 (n=16) received arthroscopic anterior compartment debridement with posterior mini-open debridement surgery, and group 2 (n=11) received arthroscopic anterior and posterior compartments debridement surgery. The elbow flexion-extension range of motion (ROM), visual analog scale (VAS), Mayo Elbow Performance Score (MEPS) were analyzed for the clinical outcome before surgery and the last follow-up visit after surgery. @*Results@#The average follow-up period was 21 months (15–32 months). All clinical outcomes (ROM, VAS, and MEPS) were improved after surgery compared to those before surgery (p<0.05) in both groups. Group 1 showed further improvement in flexion (p=0.001) and total ROM (p=0.011) than group 2. On the other hand, there was no significant difference in extension, VAS, and MEPS between the two groups. @*Conclusion@#In patients with primary elbow OA, arthroscopic anterior compartment debridement with posterior compartment mini-open technique produced an excellent clinical outcome after surgery and was particularly helpful in increasing flexion and the total ROM.
