RESUMO
Objective:To examine the correlation between intraoperative pain scores during puncturing and postoperative complications in elderly patients with osteoporotic vertebral fractures(OVF)treated with vertebroplasty(VP).Methods:In a retrospective case-control study, clinical data of 326 patients with single-segment OVF treated with VP, including 42 patients(12.9%)(the complication group)with complications within 1 month of surgery and 284 patients(87.1%)without complications(the control group), were compared.Changes in patient numerical evaluation scale(NRS)scores were recorded and compared for the complication group and the control group at different time points, which concluded preoperative(T0), intraoperative puncturing of soft tissues(T1), bone puncturing(T2), bone cement injection into the vertebral body(T3), 24 hours(T4), 1 month(T5)and 3 months(T6)after surgery.Results:NRS scores for patients in the complication group vs.those in the control group at different phase were(5.78±2.11 vs.6.10±2.21)points at T0, (7.59±1.46 vs.4.63±0.86)points at T1, (7.30±1.35 vs.5.14±1.07)points at T2, (6.97±1.24 vs.6.11±1.58)points at T3, (4.09±0.82 vs.2.19±0.87)points at T4, (2.07±0.80 vs.1.93±0.78)points at T5, and(1.83±0.72 vs.1.74±0.65)points at T6, but there was no significant difference between the two groups at T0( P>0.05).The complication group had higher NRS scores than the control group at T1, T2, T3, and T4(all P<0.05).For intra-group comparisons, both the complication group and the control group showed statistically significant differences between T0 and T4, between T0 and T5, and between T4 and T5(all P<0.05). Conclusions:Elderly OVF patients who are treated with VP and exhibit post-surgery complications often experienced severe pain during surgery, and an NRS score greater than 7 may be an independent risk factor for postoperative complications of VP.Effort should be made to avoid or reduce complications related to surgery, reduce pain and improve treatment outcomes of VP for elderly patients.
RESUMO
Objective:To compare the minimally invasive transforaminal lumbar interbody fusion (MTLIF) with open transforaminal lumbar interbody fusion (OTLIF) in treatment of lumbar degenerative disease.Methods:Clinical data of 63 patients with single segment lumbar degenerative disease treated in Department of Orthopedics of Beijing Hospital from November 2015 to September 2016 were retrospectively analyzed, among whom 30 cases received MTLIF and 33 cases received OTLIF. The operative time, intraoperative X-ray exposure times, intraoperative blood lose, postoperative drainage,perioperative fever, adjacent segment degeneration, loosening of internal fixation and cage collapse were observed in two groups 4 years after operation, and the visual analog scale (VAS) score of the lower back and the leg, the Oswestry disability index (ODI) score were compared between two groups.Results:The operation time [(191.6±50.5) min] and radiation exposure times [(15.5±6.4) times] in MTLIF group were significantly more than those in OTLIF group [(105.8±23.1) min, (7.2±1.4)times, t=17.210, t=10.850,all P<0.01]. The intraoperative blood loss [(150.4±70.4) ml], postoperative drainage [(90.4±30.7)ml], VAS score (2.4±0.7) and ODI score (24.5±3.7) 2 weeks after surgery in MTLIF group were significantly lower than those in OTLIF group [(250.7±43.9)ml,(216.3±67.8)ml,(4.5±1.6),(30.6±4.6), t=-12.830, t=-14.070, t=-6.890, t=-5.805,all P<0.01]. There were no significant differences in the incidence of fever [1 case(3.3%) vs. 4 cases(12.1%),χ2=-1.661, P=0.20], VAS score[(1.2±0.7) vs. (1.3±0.6), t=-0.628, P=0.53], ODI score[(14.2±2.7) vs. (14.7±2.5), t=-0.756, P=0.45], fusion rate of Bridwell grade Ⅰ [86.7%(26/30) vs. 84.8%(28/33),χ2=0.042, P=0.84] 1 year after surgery; and the adjacent segment degeneration [0 case(0) vs. 1 case(3.0%),χ2=0.924, P=0.34], internal fixation loosening [1 case(3.3%) vs. 1 case(3.0%),χ2=0.005, P= 0.95] and cage collapse 4 years after surgery [1 case(3.3%) vs. 1case(3.0%),χ2=0.005, P=0.95] between MTLIF group and OTLIF group. Conclusion:Compared with OTLIF, MTLIF has longer operation time and more radiation exposure, but it can achieve full decompression, the same fusion rate, less bleeding, less trauma, faster recovery, fewer complications and satisfactory long-term effect.
RESUMO
Objective:To investigate the impact of osteoporosis on clinical outcomes in elderly patients treated with short segment transforaminal lumbar interbody fusion.Methods:From May 2016 to May 2018, elderly patients who had undergone transforaminal lumbar interbody fusion(TLIF)in our hospital were retrospectively analyzed.Based on bone mineral density(BMD), patients were divided into the osteoporosis group(the OP group, n=75, T≤-2.5 in BMD)and the control group(the CO group, n=103, T>-1.0 in BMD). General patient information, clinical data and postoperative follow-up clinical results were compared between the two groups.Results:Eventually 178 cases were enrolled, including 68 with lumbar disc herniation and 110 with lumbar spinal stenosis.Preoperative Visual Analogue Scale(VAS)scores were 7.35±1.30 in the lower back and 7.32±1.30 in the leg for the OP group and 7.35±1.33 and 7.22±1.40, respectively, for the CO group, and there was no significant difference between the two groups( t=0.140 and 0.468, P=0.989 and 0.640). The proportions of cage collapse and internal fixation loosening were 70.7%(53/75)and 37.3%(28/75)in the OP group, which were higher than 22.3%(23/103)and 14.6%(15/103)in the CO group( χ2=41.440 and 12.280, both P=0.000). However, there was no significant difference between the OP group and the CO group in 1-and 2-year postoperative interbody fusion rates(postoperative 1-year rate: 89.3% or 67/75 vs.91.3% or 94/103, χ2=0.187, P=0.666; postoperative 2 year rate: 94.6% or 71/75 vs.95.1% or 98/103), χ2=0.021, P=0.885). There was no significant difference in VAS score and Oswestry disability index(ODI) between the OP group and the CO group at 6 months, 1 year and 2 years after surgery(all P>0.05). Conclusions:Although there are some osteoporosis-related complications such as cage subsidence and screw loosening, short-segment TLIF can still achieve good clinical results in elderly patients with osteoporosis.
RESUMO
Objective:To investigate the efficacy and safety of perioperative aspirin use in elderly patients with osteoporotic vertebral fractures(OVF)undergoing vertebroplasty(VP).Methods:This was a retrospective cohort study.Clinical data of 136 OVF patients treated with VP in our department from Jan.2016 to Dec.2020 were analyzed.Differences in clinical data, treatment efficacy, intraoperative and postoperative complications and hematomas were compared between the aspirin group(n=71, receiving aspirin100 mg/d before VP and not taking other anticoagulant drugs)and the control group(n=65, not taking aspirin).Results:There was no significant difference in the analgesic score or physical activity scale score between the two groups before, 1 week after surgery and at the last follow-up( P>0.05). There were significant differences in the visual analog score(VAS), the analgesic score and the physical activity scale score before, 1 week after surgery and at the last follow-up within the aspirin group(7.12±1.33, 2.37±1.01 vs.2.63±1.04, 3.01±0.95, 1.56±0.65 vs.1.61±0.57, 2.75±0.53, 1.32±0.63 vs.1.44±0.52, P<0.01). No surgical site infection, injury of large vessels, intraspinal hematoma or pulmonary embolism was found in the aspirin group or the control group during the follow-up period.There was no difference in intraoperative or postoperative blood loss(12±3.5 ml vs.11.0±3.6ml, t=1.60), cement injection volume for a single vertebral body(4.5±1.9 ml vs.4.0±1.7 ml, t=1.40), cement spillage(14 cases or 19.7% vs.9 cases or 17.0%, χ2=0.15), nerve root irritation(3 cases or 4.2% vs.1 case 1.9%, χ2=0.43), re-fractures(5 cases 7.0 vs.3 cases 5.7%, χ2=0.10)or spinal epidural hematoma(8 cases or 11.3% vs.5 cases or 9.4%, χ2=0.11)between the aspirin group and the control group(all P>0.05). Conclusions:In OVF patients taking perioperative aspirin, the postoperative pain score, pain medication administration and mobility are significantly improved after VP, compared with pre-treatment.Surgical efficacy and safety show no significant difference between patients with and without aspirin administration.
RESUMO
Objective To investigate the effectiveness of open-door laminoplasty with lateral mass screw fusion in the treatment of multisegmental cervical spondylotic myelopathy (CSM)with segmental instability.Methods Forty-one patients with multisegmental cervical spondylotic myelopathy combined with instability underwent open-door laminoplasty with lateral mass screw fusion.The JOA(Japanese Orthopaedic Association)scoring system and Neck Disability Index(NDI) were applied to evaluate neurological function and axial neck/shoulder pain before and after surgery,respectively.In addition,the Ishihara method was used to measure the cervical curvature index(CCI),and spinal cord expansion was calculated with MRI.Results After 43 months of postoperative follow-up,there were significant differences in JOA scores[(7.12±0.91) vs.(14.73± 1.12),t =35.28,P＜0.001],areas of the dural sac at the level of maximum stenosis in MRI[(0.22±0.05)]cm2 vs.(0.62±0.09)cm2,t=14.15,P＜0.001],and NDI scores[(24.46±6.61) vs.(12.90±3.46),t=15.59,P ＜ 0.001],compared with those before treatment.However,there were no significant differences in pre-and post-operation CCI[(10.36±1.69) vs.(10.87±2.05),t=1.11,P＞0.05].Conclusions Open-door laminoplasty with lateral mass screw fusion can improve neurological function and maintain the normal cervical curvature.Therefore,it is effective in the treatment of multisegmental cervical spondylotic myelopathy with segmental instability.
RESUMO
Objective To evaluate efficacy,safety and complication of percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF) in≥90 years patients.Methods Clinical data of 56 cases aged ≥ 90 years with osteoporotic vertebral compression fracture undergoing percutaneous kyphoplasty were retrospectively analyzed.Visual analog scale (VAS) score,analgesics administration score,locomotor activity score,bone cement leakage and incidence of refracture were evaluated before and 3 days after treatment,and at the last follow-up.Results The mean follow-up was 18.6 months (6-32 months) in all patients.The mean VAS score was (7.1 ±2.1) before treatment,(2.6±1.1) at 3 days after the procedure,and (1.8±0.7) at last follow-up,respectively (F=455.794,P＜0.001).Analgesics administration score were (2.0±1.7),(1.4±0.5) and (1.1±0.7) respectively before and 3 days after treatment,and at the last follow-up (F=9.631,P＜0.001).Locomotor activity score were (2.5±0.6),(1.2±0.5) and (1.0±0.3)before and 3 days after treatment,and at the last follow-up (F=63.254,P＜ 0.001) respectively.Bone cement leakage occurred in 10 cases(17.9％),recurrent fracture in 6 cases(10.7％),cerebrospinal leak in 3 cases (5.3％),and nerve root stimulation in2 cases(3.6％).Total complication rate was 33.9％(19/56),and all complications were transient and well tolerated.Conclusions Kyphoplasty for osteoporotic vertebral compression fracture in the very elderly is effective and safe.It alleviates fracture-induced pain,reduces analgesic drug use and improves spinal activity,and provides a better choice for minimal invasive treatment for nonagenarian OVCF patients.
