“…A 2013 systematic review reported that 4 RCTs found surgical intervention to be more successful than noninvasive treatment for managing pain and functional disability, while 1 RCT found no difference in future low back pain outcomes. [ 34 , 35 , 36 ] while our review also showed improvement in pain and functional disability.…”

Background: Aim of this study was to systematically review the prevailing treatment methods for lumbar spondylolysis. Methods: Manuscripts published between 1951 and 2020 were searched by using PubMed, Medline, Scopus, Springer, Web of Science databases. The study protocol was registered with PROSPERO (CRD42020218651). The inclusion criteria for all articles of prevailing treatment methods for spondylolysis were: English language; at least 1 relevant treatment method for spondylolysis; Randomized controlled trial (RCT), systematic review, comparative study, cross-sectional, cohort, and/or case control study pre-diagnosed cases of spondylolysis whereas article was excluded if any spinal deformity any neurological condition. Standards have been independently applied by using 2 reviewers and another author resolved disagreements. Results: Data extraction screened 12 full-length articles. Description, treatment, outcome, and findings were individually extracted and cross-referenced. Discussion: Current review has suggested that the noninvasive treatment method specifically low intensity pulsed ultrasound, electro acupuncture and pulsed electromagnetic filed is effective for bone union while operative treatment specifically pedicle screw fixation +/- interbody fusion depending the extent of disk degeneration and craniocaudal foraminal stenosis is effective for minimizing pain and functional disability in patients with spondylolysis. This review concluded that the noninvasive treatment method specifically low intensity pulsed ultrasound is effective for bone union. Review Registration: PROSPERO (CRD42020218651).

“…PMMA leakage is a focus point to surgeons because neurological or spinal cord damage may cause by the situation [12,18,30]. Traditionally, PMMA is injected into the preset nail tunnel using a PVP device during laddering period, and then the screw is inserted [25].…”

“…These patients may have had many comorbidities and severe osteoporosis, which resulted in complex surgical procedures might not be tolerated. In one study of Huang et al [30], they observed the clinical outcomes of traditional PMMA augmentation technology in 28 cases of Kummell's disease. The operation time, blood loss and hospitalization time were 115.9 ± 10.0 minutes, 214.3 ± 17.5 ml and 7.6 ± 1.3 days respectively.…”

Background: High-energy vertebral compression fracture (HVCFs) with osteoporosis has higher requirement for the stability of pedicle screw internal fixation system. However, few studies have involved the clinical outcome of cannulated pedicle screw to augment fixation with polymethylmethacrylate (PMMA) under this condition. This study aims to investigate the mid-term efficacy of bone cement-injectable cannulated pedicle screw (CICPS) in HVCFs with osteoporosis.Methods: Eighteen patients with HVCFs (T < -2.5) were underwent spinal fixation by CICPS from 2012 to 2017. The operation time, blood loss, and hospitalization time were recorded. Pain and functional recovery were evaluated by Visual Analog Scale VAS) and Oswestry Disability Index (ODI), respectively. X-ray films were taken to evaluate the loss of vertebral height, kyphosis angle, pedicle screw loosening, and bony fusion. Surgical related complications were also recorded.Results: The average follow-up time was 18.5 ± 8.7 months (range, 6-54 months). VAS and ODI scores indicated significant improvements in postoperative pain and activity function (P < 0.05). Comparing the last follow-up with the postoperative imaging findings, the loss of vertebral height and kyphosis angle was 3.4 ± 1.2 mm and 7.8 ± 3.8°, respectively. The rate of bone graft fusion was 100% while no cases were involved in screw loosening or extraction. 1 case of superficial infection, 2 cases of PMMA leakage, and 1 case of cerebrospinal fluid leakage were found.Conclusions: CICPS fixation using PMMA augmentation may suggest as a feasible surgical technique in osteoporotic patients with HVCFs.

“…Among various current strategies that augment the biomechanical stability of internal xation, polymethylmethacrylate-augmented cannulated pedicle screw (CPS) is currently considered the best strategy due to its high strength and rapid solidi cation [3,4]. Although this strategy is widely accepted by researchers, complications are common to be observed which mainly including nerve compression symptoms, pulmonary embolism and nerve injury due to intraoperative cement leakage (CL) [5][6][7].…”

Background We investigated the risk factors of cement leakage (CL) for polymethylmethacrylate-augmented cannulated pedicle screw (CPS) in spinal degenerative diseases and provided technical guidance for clinical surgery. Methods This study enrolled 276 patients with spinal degenerative disease and osteoporosis who were augmented using CPSs (835 screws in total) from May 2011 to June 2018 in our hospital. The patients' age, sex, bone mineral density (BMD), diagnosis, augmented positions, number of CPS implanted, and CL during surgery were recorded. CL was observed by postoperative computed tomography (CT) and was classified by Yeom typing. Results A total of 74 (8.9%) CPSs in 64 patients leaked (23.2%), with 65 (87.83%), 3 (4.05%), and 6 (8.11%) screws showing Types S, B, and C leakage, respectively. CL was significantly correlated with the number and position of screws (P < 0.05), but not with sex, age, and BMD (P > 0.05). The position, number of CPSs, fracture, degenerative scoliosis, ankylosing spondylitis, and revision surgery were risk factors for CL (P < 0.05). Augmentation of the thoracic vertebral body, fracture, and ankylosing spondylitis were independent risk factors for Type S. Augmentation of the lumbar vertebral body, lumbar disc herniation, and lumbar spondylolisthesis were independent risk factors for Type B (P < 0.05). Conclusions CL has a high incidence in clinical practice. To avoid serious complications, high-risk factors for leakage should be addressed. Particularly, it is necessary to develop alternative solutions for the lack of holding force of internal fixation caused by CL during surgery.
