Abstract Background Advances in hemodialysis have facilitated longer lifespan and better quality of life for patients with end stage renal disease (ESRD). Symptomatic degenerative lumbar diseases (DLD) becomes more common in patients with ESRD. Posterior instrumented fusion remains popular for spinal stenosis combining instability. Only a few sporadic studies mentioned about surgical outcomes in patients with ESRD underwent spine surgeries, but no one discussed about which fusion method was optimal for this kind of patients. In this study, we compared the differences between lumbar posterolateral fusion (PLF) and lumbar interbody fusion (IBF) in uremic patients underwent instrumented lumbar surgeries. Methods Between January 2005 and December 2017, ESRD patients under maintenance hemodialysis underwent posterior instrumented fusion for DLD were reviewed. A PLF group and an IBF group were identified. The demographic data was collected using their medical records. Clinical outcomes were evaluated by Oswestry Disability Index (ODI) and the visual analogue scale (VAS); radiographic results were assessed using final fusion rates. Any surgical or implant-related complication was documented. Results A total of 34 patients (22 women and 12 men, mean age of 65.4 years) in PLF group and 45 patients (26 women and 19 men, mean age of 65.1 years) in IBF group were enrolled. Both groups had similar surgical levels. The operation time was longer (200.9 vs 178.3 min, p = 0.029) and the amount of blood loss was higher (780.0 vs 428.4 ml, p = 0.001) in the IBF group. The radiographic fusion rate was better in the PLF group but without significant difference (65.2% vs 58.8%, p = 0.356). Seven in the PLF group and ten in the IBF group developed surgical complications (20.5% vs. 22.2%, p = 0.788); three patients in the PLF group (8.8%) and five patients in the IBF group (11.1%) received revision surgeries because of implant-related or wound complications. Comparing to preoperative ODI and VAS, postoperative ODI and VAS obtained significant improvement in both groups. Conclusions Successful fusion rates and clinical improvement (VAS, ODI) were similar in IBF and PLF group. Uremic patients underwent IBF for DLD had longer length of operation and higher operative blood loss than underwent PLF.

Abstract BackgroundTo explore the efficacy and safety between posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of lumbar degenerative diseases.MethodsWe searched the literature in Pubmed, Embase, Cochrane Library and Web of Science. The index words were posterior lumbar interbody fusion, PLIF, transforaminal lumbar interbody fusion, TLIF, lumbar interbody fusion, spinal fusion, degenerative disc disease and lumbar degenerative diseases. Primary outcomes were fusion rate and complications. Secondary outcomes were visual analog scale (ΔVAS), Oswestry Disability Index (ΔODI), total blood loss, operation time and length of hospital stay. Review Manager 5.3 and Stata13.1 was used for the analysis of forest plots, heterogeneity, sensitivity and publication bias.Results17 studies were included (N=1562; PLIF, n=835; TLIF, n=727). The pooled data showed PLIF had a higher complications (P= 0.000), especially in nerve injury (p = 0.003) and dural tear (p = 0.005). PLIF required longer operation time (p = 0.004), more blood loss (p = 0.000) and hospital stays (p = 0.006). Surprisingly subgroup analysis showed there was significant difference in complications in patients under 55 (p = 0.000) and Asian countries (p = 0.000). No statistical difference was found between the two groups with regard to fusion rate (p = 0.593),ΔVAS (p = 0.364) andΔODI (p = 0.237).ConclusionsThis meta-analysis showed there were no significant difference in fusion rate, ΔVAS and ΔODI. However TLIF could reduce complications, especially nerve injury and dural tear. Besides, TLIF was associated with statistically significant less blood loss, shorter operation time and shorter length of hospital stay.

Abstract Background To describe and illustrate a safe and effective technique for the placement of translaminar facet screws (TLFS) in transforaminal lumbar interbody fusion (TLIF). Methods Forty-two patients with single-level lumbar diseases were divided into two groups randomly. 21 patients were treated by traditional TLIF using bilateral pedicle screws fixation (BPS) while the other patients underwent insertion of a unilateral pedicle screw (UPS)and contralateral TLFS using our modified technique. In this technique, a small unicortical “hole” was formed adjacent to the contralateral facet joint to ensure that insertion of the screw could be directly visualized through the hole to prevent violation of the spinal canal. The ODI, JOA, VAPS questionnaire, the mean operation time, mean operative blood loss, length of stay and postoperative complications were collected for analysis. Results There is no significant difference between the BPS and UPS + TLFS group in the preoperative and postoperative ODI, JOA or VAPS at each follow- up visit, while the UPS + TLFS group using our modified technique significantly reduced the mean operation time, the mean estimated blood loss and the length of stay. These results demonstrated this modified technique to be safe and effective in TLIF. Conclusions In contrast to conventional TLIF, our modified technique for placing TLFS in TLIF can reduce soft tissue injuries, reduce the operation risk of violation of the spinal canal and the expenses, minimize radiation exposure, and shorten the length of the operation without a concurrent reduction in clinical efficacy.

Abstract Background: This study evaluated the clinical and imaging results of oblique lumber interbody fusion (OLIF) and posterior lumbar interbody fusion (PLIF) in the treatment of degenerative lumbar diseases.Methods: The clinical data of 99 patients with degenerative lumbar diseases in the Third Hospital of Hebei Medical University from January 2016 to January 2018 were analyzed retrospectively. 49 cases were dealt with by OLIF (stand-alone) (OLIF group) and 50 cases with PLIF (PLIF group). Clinical and imaging data were collected before surgery and at each follow-up visit. Clinical data included operation time, blood loss, incision length, length of hospital stay, visual analogue score (VAS), Oswestry dysfunction index (ODI), Japanese orthopaedic association (JOA) scores and complications. imaging measurment included the height of segmental intervertebral space, lumbar lordotic angle, operative segmental lordotic angle and fusion rate. The relationship between clinical results and radiology was assessed by comparing the radiological results before and after operation.Results: 99 cases of interbody fusion were performed successfully, and all patients had clinical improvement. The follow-up time was 24-38 months. The operation time, intraoperative blood loss, incision length and hospital stay in OLIF group were significantly less than those in the PLIF group (p<0.05). The intervertebral disc height, lumbar lordotic angle and operative segmental lordotic angle in the two groups were significantly enhanced compared with those before operation, and the difference was statistically significant (p<0.05). All of them achieved satisfactory fusion effect. Complications were found in 5 cases in OLIF group and 13 cases in PLIF group.Conclusion: Both OLIF and PLIF are effective in the treatment of degenerative lumbar diseases. Compared with PLIF, OLIF has a lot advantages in early stage after operation, However, similar clinical outcomes were achieved in the two approaches at mid-term follow-up visit.

Abstract Background This present study is aimed to retrospectively assess the efficacy of three-dimensional (3D) printing assisted osteotomy guide plate in accurate osteotomy of adolescent cubitus varus deformity. Material and methods Twenty-five patients (15 males and 10 females) with the cubitus varus deformity from June 2014 to December 2017 were included in this study and were enrolled into the conventional group (n = 11) and 3D printing group (n = 14) according to the different surgical approaches. The operation time, intraoperative blood loss, osteotomy degrees, osteotomy end union time, and postoperative complications between the two groups were observed and recorded. Results Compared with the conventional group, the 3D printing group has the advantages of shorter operation time, less intraoperative blood loss, higher rate of excellent correction, and higher rate of the parents’ excellent satisfaction with appearance after deformity correction (P < 0.001, P < 0.001, P = 0.019, P = 0.023). Nevertheless, no significant difference was presented in postoperative carrying angle of the deformed side and total complication rate between the two groups (P = 0.626, P = 0.371). Conclusions The operation assisted by 3D printing osteotomy guide plate to correct the adolescent cubitus varus deformity is feasible and effective, which might be an optional approach to promote the accurate osteotomy and optimize the efficacy.

Background and objectives: Oblique Lateral Interbody Fusion (OLIF) is a widely performed, minimally invasive technique to achieve lumbar lateral interbody fusion. However, some complications can arise due to constraints posed by the limited surgical space and visual field. The purpose of this study was to assess the short-term postoperative clinical outcomes of microendoscopy-assisted OLIF (ME-OLIF) compared to conventional OLIF. Materials and Methods: We retrospectively investigated 75 consecutive patients who underwent OLIF or ME-OLIF. The age, sex, diagnosis, and number of fused levels were obtained from medical records. Operation time, estimated blood loss (EBL), and intraoperative complications were also collected. Operation time and EBL were only measured per level required for the lateral procedure, excluding the posterior fixation surgery. The primary outcome measure was assessed using the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ). The secondary outcome measure was assessed using the Oswestry Disability Index (ODI) and the European Quality of Life–5 Dimensions (EQ-5D), measured preoperatively and 1-year postoperatively. Results: This case series consisted of 14 patients in the OLIF group and 61 patients in the ME-OLIF group. There was no significant difference between the two groups in terms of the mean operative time and EBL (p = 0.90 and p = 0.50, respectively). The perioperative complication rate was 21.4% in the OLIF group and 21.3% in the ME-OLIF group (p = 0.99). In both groups, the postoperative JOABPEQ, EQ-5D, and ODI scores improved significantly (p < 0.001). Conclusions: Although there was no significant difference in clinical results between the two surgical methods, the results suggest that both are safe surgical methods and that microendoscopy-assisted OLIF could serve as a potential alternative to the conventional OLIF procedure.

Study Design: Systematic review and meta-analysis. Objectives: Arthrodesis has been a valid treatment option for spinal diseases, including spondylolisthesis and lumbar spinal stenosis. Posterolateral and posterior lumbar interbody fusion are amongst the most used fusion techniques. Previous reports comparing both methods have been contradictory. Thus, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to establish substantial evidence on which fusion method would achieve better outcomes. Methods: Major databases including PubMed, Embase, Web of Science and CENTRAL were searched to identify studies comparing outcomes of interest between posterolateral fusion (PLF) and posterior lumbar interbody fusion (PLIF). We extracted data on clinical outcome, complication rate, revision rate, fusion rate, operation time, and blood loss. We calculated the mean differences (MDs) for continuous data with 95% confidence intervals (CIs) for each outcome and the odds ratio with 95% confidence intervals (CIs) for binary outcomes. P < 0.05 was considered significant. Results: We retrieved 8 studies meeting our inclusion criteria, with a total of 616 patients (308 PLF, 308 PLIF). The results of our analysis revealed that patients who underwent PLIF had significantly higher fusion rates. No statistically significant difference was identified in terms of clinical outcomes, complication rates, revision rates, operation time or blood loss. Conclusions: This systematic review and meta-analysis provide a comparison between PLF and PLIF based on RCTs. Although PLIF had higher fusion rates, both fusion methods achieve similar clinical outcomes with equal complication rate, revision rate, operation time and blood loss at 1-year minimum follow-up.

Abstract Purpose The Nice knots have been widely used in orthopedic surgeries to fix torn soft tissue and fracture in recent years. The study aims to investigate the clinical efficacy and prognosis of intraoperative and postoperative Nice Knots-assisted reduction in the treatment of displaced comminuted clavicle fracture. Methods From Jan 2014 to Dec 2019, 75 patients diagnosed with unilateral closed displaced comminuted clavicle fracture were treated with open reduction and internal fixation (ORIF) in this study. Nice knot group (the NK group) included 38 patients and the other 37 patients were in the traditional group (the TK group). The time of operation and the amount of bleeding during operation were recorded. Post-operative clinical outcomes and radiographic results were recorded and compared between these two groups. The Visual Analogue Scale (VAS), Neer score, Rating Scale of the American Shoulder and Elbow Surgeons, Constant-Murley score and complications such as infection, nonunion, implant loosening, fragment displacement and hardware pain were observed in the two groups. Results In the comparison between the two groups, there was no significant difference in age, sex, the cause of displaced clavicle fracture, and other basic information between the two groups. The operation time, intraoperative fluoroscopy time, and intraoperative blood loss were significantly reduced in the NK group (P < 0.01). There were 2 cases of plate fracture in the TK group. The follow-up results showed that there was no significant difference in VAS, Neer score, ASES, and Constant-Murley scores between the two groups. Conclusion The use of Nice knot, in comminuted and displaced clavicle fractures can reduce intraoperative blood loss, shorten operation time, facilitate intraoperative reduction, and achieve satisfactory postoperative clinical results. This study demonstrates that Nice knot is a simple, safe, practical and effective auxiliary reduction method.

BACKGROUND An ideal surgery to remove hypertrophied adenoid mass should be safe, with less bleeding and operation time along with post-operative improvement in the eustachian tubal ventilation and normal respiration. It should also have low morbidity and mortality. Among the various methods described for its removal, the two commonly used methods are conventional cold curettage method and coblation technique. The purpose of this study was to collate the safety and efficacy of endoscopic coblation adenoidectomy with the conventional curettage adenoidectomy. METHODS A prospective comparative study with fifty patients was studied who underwent adenoidectomy. Twenty five patients underwent endoscopy assisted coblation adenoidectomy and twenty five patients underwent regular adenoidectomy by curettage. RESULTS Patients who underwent coblation adenoidectomy showed better results during follow up in terms of completeness of removal. 80 % of children undergoing regular adenoidectomy by curettage method showed remnant adenoid tissue in the nasopharynx at the end of the procedure. But it was 6 % among the children undergoing endoscopic assisted coblation adenoidectomy. The mean duration of operation was higher for endoscopic assisted coblation adenoidectomy which was significant statistically. The mean blood loss was 30.36 ml in regular curettage adenoidectomy; 10.6 ml with endoscopic coblation adenoidectomy. The grading of pain was significantly lower in endoscopic assisted coblation adenoidectomy. There was no significant difference between two groups in terms of eustachian tube function after surgery. CONCLUSIONS Coblation adenoidectomy has significant advantages over conventional adenoidectomy in terms of completeness of removal, reduced blood loss, and lower post-operative pain grade.

Abstract PurposeTo compare the efficacy and safety of percutaneous short-segment pedicle screws fixation (PPSF) with or without intermediate screws (IS) for the treatment of thoracolumbar compression fractures.MethodsFrom January 2016 to March 2019, a retrospective study of 38 patients with thoracolumbar compression fractures conducted. The patients were divided into a 4-screw group (without IS) and a 6-screw group (with IS) according to whether pedicle screws were placed in the fractured vertebrae. Combined positional reduction effects with the technique of pre-contoured lordotic rods were used to reduce the fracture by lengthening the anterior column of the fractured vertebrae. The posterior structure of the fractured vertebrae was undertaken as the fulcrum point for both groups. The operation time, intra-operative blood loss, visual analogue scale (VAS), anterior vertebral body height (AVBH), segment kyphosis（SK）before and after operation and complications were recorded.ResultsAlthough the operation time and blood loss in the 6-screw group were higher than in the 4-screw group, difference was not significant (P＞0.05). There was no significant difference in VAS, AVBH and SK between the two groups (P＞0.05). Nevertheless, these results were significant differences between the preoperative and the immediate postoperative, between preoperative and follow-up groups (P < 0.001). No neurologic injury was observed in either groups. ConclusionsIn the treatment of thoracolumbar compression fractures, percutaneous short-segment pedicle screws fixation without intermediate screws in the 4-screw construct may obtain the same clinical effect as that in the 6-screw construct.
