MRI features of testicular spermatic granuloma

Abstract

This is a meta-analysis to compare the results between laminoplasty and laminectomy followed by fusion for the patients with multilevel cervical compressive myelopathy. An extensive search of literature was performed in MEDLINE, Embase, the Cochrane library, CNKI, and WANFANG. The following outcome measures were extracted: the Japanese Orthopaedic Association (JOA) scores, cervical curvature index (CCI), visual analog scale (VAS), cervical lordosis (C2–7), complications, blood loss, and operation time. Data analysis was conducted with RevMan 5.3 and STATA 12.0. A total of 23 studies comprising 774 and 743 patients treated with laminoplasty and laminectomy followed by fusion, respectively, were included in the final analysis. The pooled analysis showed that there was no significant difference in preoperative JOA scores [P = 0.89], postoperative JOA scores [P = 0.13], JOA scores improvement rate [P = 0.27], preoperative CCI [P = 0.15], postoperative CCI [P = 0.14], preoperative VAS [P = 0.41], postoperative VAS [P = 0.52], preoperative cervical lordosis (C2–7) [P = 0.46], postoperative cervical lordosis (C2–7) [P = 0.67], total complications [P = 0.07], axial pain [P = 0.94], and blood loss [P = 0.51]. However, there were significant difference in operation time (WMD = −19.57 [−32.11, −7.02], P = 0.002) and C5 palsy (OR = 0.26 [0.15, 0.44], P < 0.001). As compared with laminectomy followed by fusion, expansive laminoplasty showed no significant differences in JOA scores, CCI, ROM, VAS, cervical lordosis (C2–7), axial pain, total complications, and blood loss, but shorter operation time and fewer C5 palsy.

Cervical Spondylotic Myelopathy: Pathophysiology and Surgical Approaches

“…Liu et al [33] showed that both techniques increased the JOA score postoperatively and resulted in similar improvements in the VAS score.…”

“…A recent study by Liu et al [33] reported that both techniques resulted in no difference in postoperative cervical curvature index and cervical Cobb's angle. However, the authors [33] suggested to select laminectomy with fusion in severe preoperative cervical kyphotic patients.…”

“…They found that both procedures caused several complications including kyphosis, C5 paresis, infection, subluxation, instability, CSF leakage, wound dehiscence, urinary retention, chronic pain, restenosis, nonunion, hardware failure, and revision surgery. However, there was no significant difference in the complications between both techniques [33,48]. Woods et al [47] reported laminoplasty exhibited higher incidence of complication (13%) than laminectomy and fusion (9%).…”

“…The meta-analysis study by Liu et al [33] reported that laminoplasty exhibited shorter operation time than laminectomy. Similarly, Lao et al [48] also noted that the average operation time in laminoplasty was shorter than laminectomy (137.4 min and 142.6 min, respectively).…”
