Background: Chronic low back pain secondary to degenerative disc disease is a significant public health issue worldwide, contributing to substantial health care burdens and patient disability. Anterior lumbar interbody fusion (ALIF) has emerged as a promising surgical solution, offering benefits such as disc height restoration, reduced neural compression, and improved spinal alignment. This study evaluates the efficacy of stand-alone ALIF using polyetheretherketone (PEEK) cages, structural femoral head allografts, and recombinant human bone morphogenetic protein-2 (rhBMP-2) in treating discogenic low back pain caused by degenerative disc disease.

Methods: This prospective case series study included 1335 patients who underwent stand-alone ALIF by a single surgeon. The surgical construct involved PEEK cages with structural femoral allograft dowels and rhBMP-2, supplemented by anterior fixation. Patient-reported outcome measures, including the visual analog scale for back and leg pain, the Oswestry Disability Index, the Roland-Morris Disability Questionnaire, and patient satisfaction, were monitored over 12 months.

Results: The overall fusion rate was 99.6%, with pseudoarthrosis occurring in 0.2% of patients. Lower fusion rates were observed in patients older than 65 years and those using the Brantigan cage. Significant improvements were seen in visual analog scale for back and leg pain, Oswestry Disability Index, and Roland-Morris Disability Questionnaire scores from baseline, with most scores exceeding the substantial clinical benefit thresholds. More than 85% of patients reported "Excellent" or "Good" outcomes.

Conclusions: Stand-alone ALIF, augmented with rhBMP-2 and structural femoral head allografts, can enhance mechanical stability, fusion rates, and radiographic assessment. This integrated approach achieves successful spinal fusion and positive clinical outcomes for patients with refractory discogenic low back pain.

Clinical relevance: Stand-alone ALIF with PEEK cages, structural femoral head allografts, and rhBMP-2 demonstrates high fusion rates and significant clinical improvements in patients with discogenic low back pain. This approach enhances spinal stability and promotes biological healing, making it a reliable and effective surgical option.

Background: Previous analyses have suggested variations in cervical spine canal morphology according to ethnicity, possibly in part due to variations in the posterior elements. The potential for these variations to affect the placement of instrumentation is uncertain. The aim of this study was to report on the feasibility of C2 lamina screw insertion in a New Zealand cohort including analysis of Māori, the indigenous people of New Zealand.

Methods: A trauma computed tomography database was accessed to identify suitable images. On axial images, where the isthmus was at its widest, the outer diameter (OD) and inner diameter (ID) of the lamina were measured. Screw length was measured from a proposed entry point to the contralateral junction of the lamina and lateral mass. The spinolaminar angle was measured as the angle subtended by the screw trajectory and midsagittal plane. A 5.5-mm OD was accepted as a threshold for the feasibility of lamina screw placement.

Results: One hundred eighty-seven images were assessed: 115 New Zealand European and 72 Māori. The mean age of the cohort was 41.9 years (SD 19.6), and most patients (64%) were men. For the entire cohort, mean OD was 6.6 and 6.8 mm on the right and left, respectively; the mean inner diameter was 3.5 and 3.8 mm; mean screw length was 31.5 and 31.5 mm; and mean spinolaminar angle was 46.0° and 46.1°. C2 lamina screw placement was feasible in a majority of patients. Considering only Māori patients, placement was feasible in 96% of right and 94% of left laminae in men but 72% of right and 72% of left laminae in women.

Conclusions: In a majority of patients, C2 lamina screw placement is feasible. However, advanced imaging must be carefully assessed preoperatively because data suggest that Māori women may not necessarily have optimal anatomy.

Clinical relevance: Care needs to be taken when assessing and planning surgery inpatients of different ethnicities because variations may exist in the morphology of the posterior elements of C2, leading to variation in optimal fixation strategy.

背景:以前的分析表明,不同种族的人颈椎管形态存在差异,部分原因可能是后部元素的变化。这些差异对器械置放的潜在影响尚不确定。本研究旨在报告在新西兰队列中插入 C2 椎板螺钉的可行性,包括对新西兰原住民毛利人的分析:方法:访问创伤计算机断层扫描数据库以确定合适的图像。在峡部最宽的轴向图像上,测量了薄层的外径(OD)和内径(ID)。螺钉长度的测量是从拟进入点到对侧椎板和侧块交界处。脊柱板层角是根据螺钉轨迹与中矢状面的夹角测量的。5.5毫米的外径被认为是脊柱骨板螺钉置入可行性的阈值:结果:共评估了 187 张图像:115名新西兰欧裔和72名毛利人。患者的平均年龄为 41.9 岁(SD 19.6),大多数患者(64%)为男性。在整个组群中,右侧和左侧的平均外径分别为6.6毫米和6.8毫米;平均内径分别为3.5毫米和3.8毫米;平均螺钉长度分别为31.5毫米和31.5毫米;平均脊柱板角度分别为46.0°和46.1°。大多数患者都能进行 C2 椎板螺钉置入术。仅考虑毛利患者,在男性患者中,96%的右椎板和94%的左椎板可行螺钉置入,而在女性患者中,72%的右椎板和72%的左椎板可行螺钉置入:结论:在大多数患者中,C2 椎板螺钉置入是可行的。然而,术前必须仔细评估先进的成像技术,因为数据表明毛利女性不一定具有最佳的解剖结构。临床相关性在评估和规划不同种族患者的手术时需要注意,因为C2后部元素的形态可能存在差异,从而导致最佳固定策略的不同。

Background: Atlantoaxial transarticular fixation, also called the Magerl technique, is said to be the most robust biomechanical method of fixation of the atlantoaxial vertebrae. However, the procedure carries a risk of spinal cord and vertebral artery injury during the insertion process, especially in patients with a high-riding vertebral artery. In this study, a computed tomography (CT)-based navigation system was used for preoperative planning and insertion. This investigation sought to determine the rate and direction of screw perforation as well as the incidence of screw loosening in computer-assisted atlantoaxial transarticular fixation.

Methods: Sixty patients (31 men and 29 women; mean ± SD age: 65.3 ± 19.6 years) who received atlantoaxial transarticular screw insertion with preoperative CT navigation were analyzed. We investigated screw position and loosening by CT at the final follow-up.

Results: Of the 108 screws inserted, the rate of Grade 2 or higher perforation was 4.6% (5/108). Nine of 81 (11.1%) screws inserted into the 44 patients who were followed for at least 6 months showed loosening. Logistic regression analysis revealed that unilateral insertion (odds ratio: 8.50, 95% confidence interval: 1.53-47.2, P = 0.014) was significantly associated with the incidence of screw loosening.

Conclusions: The screw perforation rate of Grade 2 or higher in computer-assisted atlantoaxial transarticular screw fixation was 4.6%, with comparable frequencies of perforation direction. Unilateral insertion was a significant independent factor associated with screw loosening, which occurred in 11.1% of insertions.

Clinical relevance: Spine surgeons should follow up with patients with caution because screws with unilateral insertion are prone to loosening.

背景:寰枢椎经关节固定术,又称 Magerl 技术,据说是固定寰枢椎最稳固的生物力学方法。然而,该手术在插入过程中存在脊髓和椎动脉损伤的风险,尤其是在椎动脉高位患者中。本研究采用基于计算机断层扫描(CT)的导航系统进行术前规划和插入。这项研究旨在确定计算机辅助寰枢椎经关节固定术中螺钉穿孔的比率和方向以及螺钉松动的发生率:分析了 60 例接受寰枢椎经关节螺钉植入术的患者(男性 31 例,女性 29 例;平均 ± SD 年龄:65.3 ± 19.6 岁),他们在术前均接受了 CT 导航。我们在最后随访时通过 CT 调查了螺钉的位置和松动情况:在插入的108枚螺钉中,2级或以上穿孔率为4.6%(5/108)。在接受至少 6 个月随访的 44 位患者中,81 枚螺钉中有 9 枚(11.1%)出现松动。逻辑回归分析显示,单侧插入(几率比:8.50,95% 置信区间:1.53-47.2,P = 0.014)与螺钉松动的发生率显著相关:计算机辅助寰枢椎经关节螺钉固定术中2级或以上的螺钉穿孔率为4.6%,穿孔方向的频率相当。单侧插入是与螺钉松动相关的重要独立因素,11.1%的插入发生了螺钉松动:临床意义:脊柱外科医生应谨慎随访患者,因为单侧插入的螺钉容易发生松动:4:

Background: Biportal endoscopic spine surgery (BESS) has become widely recognized as a minimally invasive method for spinal decompression and discectomy. However, postoperative epidural hematoma (POEH) presents a significant risk in spinal surgery due to its potential to compress neural elements and lead to neurological deficits. This study compares the clinical and radiological outcomes of BESS with those of conventional microscopic surgery.

Methods: In this single-center, single-blinded, actively controlled randomized clinical trial, 46 patients undergoing single-level posterior decompression or discectomy for spinal stenosis or herniated intervertebral discs were enrolled. Participants were randomly allocated to either the conventional microscopic surgery group or the BESS group. Experienced spine surgeons performed all procedures. Postoperative magnetic resonance imaging assessments were conducted following the removal of the drain system. Outcome measures included the cross-sectional area (CSA) of the dura sac and POEH, as well as the incidence of neurological deficits.

Results: The demographic and baseline characteristics of the patients were similar across the 2 groups, with 24 in the conventional group and 22 in the BESS group. There were no significant differences in the preoperative and postoperative CSA of the dura sac between the groups. However, the BESS group exhibited a significantly larger CSA of POEH (0.36 ± 0.34 cm²) compared with the conventional group (0.17 ± 0.15 cm², P = 0.033). Despite this higher incidence of POEH, there was no corresponding increase in neurological deficits or revision surgeries.

Conclusion: The findings indicate that while BESS achieves decompression comparable to that of conventional microscopic surgery, it is associated with a higher incidence of epidural hematomas. Importantly, these hematomas did not result in an increased rate of neurological deterioration or the need for surgical interventions. Further studies with larger sample sizes and extended follow-up are required to confirm these results and further refine the BESS technique.

Clinical relevance: Despite a higher incidence of epidural hematomas, BESS offers comparable decompression to microscopic surgery without increased neurological risks, making it a viable, less invasive option for patient care.

背景:双入口内窥镜脊柱手术(BESS)已被广泛认为是脊柱减压和椎间盘切除术的微创方法。然而,由于术后硬膜外血肿(POEH)可能压迫神经元并导致神经功能缺损,因此在脊柱手术中存在很大风险。本研究比较了 BESS 与传统显微手术的临床和放射学结果:在这项单中心、单盲、主动控制的随机临床试验中,共招募了46名因椎管狭窄或椎间盘突出而接受单水平后路减压或椎间盘切除术的患者。参与者被随机分配到传统显微手术组或 BESS 组。所有手术均由经验丰富的脊柱外科医生实施。术后在移除引流系统后进行磁共振成像评估。结果测量包括硬膜囊横截面积(CSA)、POEH以及神经功能缺损的发生率:两组患者的人口统计学特征和基线特征相似,传统组 24 人,BESS 组 22 人。两组患者术前和术后硬膜囊 CSA 无明显差异。不过,BESS 组 POEH 的 CSA(0.36 ± 0.34 平方厘米)明显大于传统组(0.17 ± 0.15 平方厘米,P = 0.033)。尽管POEH发生率较高,但神经功能缺损或翻修手术并未相应增加:研究结果表明,虽然 BESS 的减压效果与传统显微手术相当,但硬膜外血肿的发生率较高。重要的是,这些血肿并没有导致神经功能恶化或手术干预需求的增加。要证实这些结果并进一步完善 BESS 技术,还需要进行样本量更大、随访时间更长的进一步研究:尽管硬膜外血肿的发生率较高,但BESS的减压效果与显微手术相当,且不会增加神经系统风险,因此是一种可行的、创伤较小的患者护理选择:

Introduction: Breast asymmetry (BA) is a common condition in patients with adolescent idiopathic scoliosis (AIS). Physicians may misdiagnose a patient with a unilateral breast tumor as a normal condition related to scoliosis. The present report describes the case of a patient with a breast tumor that was detected incidentally after surgical correction of scoliosis.

Patient presentation and outcomes: A 21-year-old woman was diagnosed as having AIS and reported to our institute for management. Thoracic third to lumbar second vertebra instrumented spine de-rotation and associated fusion surgery were performed to correct the deformity. After the operation, enlargement of left breast volume and obvious BA were noted. Breast sonography was performed, and a large tumor was found. Finally, the biopsy revealed a fibroadenoma of the left breast.

Conclusions: In managing patients with scoliosis and BA, comprehensive consideration of other possible etiologies is crucial to prevent misdiagnosis. This article reminds physicians that breast tumors can be concealed by BA related to AIS.

Background: Biportal endoscopic transforaminal lumbar interbody fusion (BE-TLIF) is a minimally invasive TLIF (MIS-TLIF) technique, commonly performed with various cage types. Expandable cages are particularly effective in achieving segmental lordosis (SL) and disc height (DH) elevation in minimally invasive TLIF. However, the published literature lacks details regarding how these outcomes can be accomplished using BE-TLIF with an expandable cage.

Methods: Nine cases (10 levels) of BE-TLIF with an expandable cage were reviewed. Procedures including unilateral laminotomy and bilateral decompression, cage expansion trials, and bilateral facetectomies were carried out under biportal endoscopy to achieve SL and DH elevation. Postoperative standing x-ray images at 3 months and reconstructed computed tomography images were analyzed. The sublaminar decompression angle-measured as the angle between the spinous process and the sublaminar decompression line on axial computed tomography-was used to evaluate contralateral sublaminar decompression.

Results: All procedures were completed without changes to the surgical methods. Eight patients underwent single-level fusion, with 4 of them receiving additional decompression at adjacent levels. One patient underwent a 2-level fusion. Four cases utilized 12° lordotic cages, while the rest employed 20° hyperlordotic cages. The total time for each fusion was 152.5 ± 38.5 minutes. Segmental lordosis increased by 5.1°, with anterior and posterior DH elevations of 4.8 ± 1.7 mm and 3.1 ± 1.8 mm, respectively. No endplate injuries or early cage subsidence occurred. The mean sublaminar decompression angle was 31.8° ± 7.0°.

Conclusions: BE-TLIF with an expandable cage may offer benefits in SL correction and DH elevation. These advantages are attributed to the use of more lordotic expandable cages, combined with contralateral facetectomies and careful endplate preparation-key features of the BE-TLIF technique.

Clinical relevance: SL correction and DH elevation can be achieved through BE-TLIF, which helps to reduce the recurrence of symptoms and improves the lumbar lordotic curve.

Cervical intradural meningioma are rare central nervous system neoplasms. Surgical resection is the primary treatment due to the tumor's benign nature and clear demarcation from the spinal cord, although the posterior surgical approach can result in complications such as neurological deficits and cerebrospinal fluid leaks. We present a case of a 78-year-old woman with progressive clumsiness, gait disturbance, and weakness. She was diagnosed with an intradural extramedullary meningioma at the C2 to C3 level through magnetic resonance imaging. The tumor was excised using a cervical biportal endoscopic spine surgery approach, a minimally invasive technique that utilizes 2 small portals for endoscope and instrument access. The procedure, performed under general anesthesia, involved a hemilaminectomy and partial laminectomy to access and remove the tumor. Postoperative assessments indicated significant neurological recovery, with the patient regaining independent mobility and fine motor skills. Follow-up magnetic resonance images at 18 months confirmed the absence of tumor recurrence. This case demonstrates the efficacy of cervical biportal endoscopic spine surgery in managing high cervical intradural tumors, highlighting its potential for reducing surgical complications and promoting rapid patient recovery.

颈椎硬膜内脑膜瘤是一种罕见的中枢神经系统肿瘤。由于肿瘤为良性,且与脊髓分界清楚,手术切除是主要的治疗方法,但后路手术可能会导致神经功能缺损和脑脊液漏等并发症。我们介绍了一例 78 岁女性的病例,她患有进行性笨拙、步态障碍和乏力。通过磁共振成像,她被诊断为 C2 至 C3 水平的硬膜外脑膜瘤。采用颈椎双入口内窥镜脊柱手术方法切除了肿瘤,这是一种微创技术,利用两个小口进入内窥镜和器械。手术在全身麻醉下进行,包括半椎板切除术和部分椎板切除术,以进入并切除肿瘤。术后评估显示,患者的神经功能得到了明显恢复,恢复了独立活动能力和精细运动技能。18 个月的随访磁共振图像证实肿瘤没有复发。本病例展示了颈椎双门内窥镜脊柱手术在治疗高位颈椎硬膜内肿瘤方面的疗效,凸显了其在减少手术并发症和促进患者快速康复方面的潜力。

Background: Nowadays, minimally invasive lateral lumbar interbody fusion (LLIF) is used to treat degenerative lumbar spine disease. Many studies have proven that LLIF results in less soft tissue destruction and rapid recovery compared with open posterior lumbar interbody fusion (PLIF). Our recent cost-utility study demonstrated that LLIF was not cost-effective according to the Thai willingness-to-pay threshold, primarily due to the utilization of an expensive bone substitute: bone morphogenetic protein 2. Therefore, this study was designed to use less expensive tricalcium phosphate combined with iliac bone graft (TCP + IBG) as a bone substitute and compare cost-utility analysis and clinical outcomes of PLIF in Thailand.

Methods: All clinical and radiographic outcomes of patients who underwent single-level LLIF using TCP + IBG and PLIF were retrospectively collected. Preoperative and 2-year follow-up quality of life from EuroQol-5 Dimensions-5 Levels and health care cost were reviewed. A cost-utility analysis was conducted using a Markov model with a lifetime horizon and a societal perspective.

Results: All enrolled patients were categorized into an LLIF group (n = 30) and a PLIF group (n = 50). All radiographic results (lumbar lordosis, foraminal height, and disc height) were improved at 2 years of follow-up in both groups (P < 0.001); however, the LLIF group had a dramatic significant improvement in all radiographic parameters compared with the PLIF group (P < 0.05). The fusion rate for LLIF (83.3%) and PLIF (84%) was similar and had no statistical significance. All health-related quality of life (Oswestry Disability Index, utility, and EuroQol Visual Analog Scale) significantly improved compared with preoperative scores (P < 0.001), but there were no significant differences between the LLIF and PLIF groups (P > 0.05). The total lifetime cost of LLIF was less than that of PLIF (15,355 vs 16,500 USD). Compared with PLIF, LLIF was cost-effective according to the Thai willingness-to-pay threshold, with a net monetary benefit of 539.76 USD.

Conclusion: LLIF with TCP + IBG demonstrated excellent radiographic and comparable clinical health-related outcomes compared with PLIF. In economic evaluation, the total lifetime cost was lower in LLIF with TCP + IBG than in PLIF. Furthermore, LLIF with TCP + IBG was cost-effective compared with PLIF according to the context of Thailand.

Clinical relevance: LLIF with less expensive TCP + IBG as bone graft results in better clinical and radiographic outcomes, less lifetime cost, and cost-effectiveness compared with PLIF. This suggests that LLIF with TCP + IBG could be utilized in lower- and middle-income countries for treating patients with degenerative disc disease.

背景:如今,微创侧腰椎椎间融合术(LLIF)已被用于治疗退行性腰椎疾病。许多研究证明,与开放式后路腰椎椎间融合术(PLIF)相比,LLIF 对软组织的破坏更小,术后恢复更快。我们最近的成本效用研究表明,根据泰国人的支付意愿阈值,LLIF 并不具有成本效益,这主要是由于使用了昂贵的骨替代物:骨形态发生蛋白 2。 因此,本研究旨在使用价格较低的磷酸三钙结合髂骨移植(TCP + IBG)作为骨替代物,并比较泰国 PLIF 的成本效用分析和临床结果:回顾性收集了使用 TCP + IBG 和 PLIF 进行单层 LLIF 患者的所有临床和影像学结果。方法:回顾性收集了使用 TCP + IBG 和 PLIF 的单层 LLIF 患者的所有临床和放射学结果,并根据 EuroQol-5 Dimensions-5 级别对术前和 2 年随访的生活质量以及医疗费用进行了审查。采用马尔可夫模型进行了成本效用分析,该模型具有终生视角和社会视角:所有入组患者被分为 LLIF 组(30 人)和 PLIF 组(50 人)。两组患者的所有影像学结果(腰椎前凸、椎孔高度和椎间盘高度)在随访2年后均有所改善(P < 0.001);但与PLIF组相比,LLIF组的所有影像学参数均有显著改善(P < 0.05)。LLIF(83.3%)和PLIF(84%)的融合率相似,无统计学意义。与术前评分相比,所有与健康相关的生活质量(Oswestry残疾指数、效用和EuroQol视觉模拟量表)均有显著改善(P < 0.001),但LLIF组和PLIF组之间无显著差异(P > 0.05)。LLIF 的终生总费用低于 PLIF(15,355 美元对 16,500 美元)。根据泰国的支付意愿阈值,与PLIF相比,LLIF具有成本效益,净货币收益为539.76美元:结论:与 PLIF 相比,使用 TCP + IBG 的 LLIF 具有良好的放射学效果和可比的临床健康相关结果。在经济评估中,TCP + IBG LLIF 的终生总费用低于 PLIF。此外,根据泰国的具体情况,采用 TCP + IBG 的 LLIF 与 PLIF 相比更具成本效益:临床相关性:与 PLIF 相比,使用价格较低的 TCP + IBG 作为骨移植的 LLIF 可获得更好的临床和影像学效果、更少的终生费用和成本效益。这表明,在中低收入国家,使用 TCP + IBG 进行 LLIF 可用于治疗椎间盘退行性疾病患者:3:

Background: Venous thromboembolism (VTE) is a well-known complication after spine surgery. As many cases of cervical spine disease result in severe gait disturbance due to myelopathy, it may harbor a higher risk of VTE than other spinal disorders. However, few studies have focused primarily on cervical spine surgery to date. This investigation sought to determine the prevalence of VTE after cervical spine surgery and identify patient-based risk factors.

Methods: The medical data of 341 consecutive patients (240 men and 101 women; mean age, 68.1 years) who underwent cervical spine surgery were retrospectively examined. Logistic regression models were employed to examine the prevalence, characteristics, and risk factors of postoperative VTE.

Results: In this study, 2.6% of cervical spine surgery patients experienced postoperative VTE. In comparisons of VTE and non-VTE groups, significant differences were found for age (79.6 years vs 67.7 years, P < 0.01), 1-week postoperative D-dimer level (10.6 μg/mL vs 2.7 μg/mL, P < 0.01), and cardiovascular disease (44.4% vs 11.1%, P = 0.011). Multivariate analysis identified elevated postoperative D-dimer level and cardiovascular disease as significantly associated with postsurgical VTE with respective odds ratios of 1.54 and 9.52.

Conclusion: Postoperative VTE in cervical spine surgery was seen in 2.6% of cases. Patients with elevated postoperative D-dimer level and cardiovascular disease may be at increased risk of VTE and may require additional observation.

Clinical relevance: Spine surgeons should take into account that patients with elevated postoperative D-dimer levels and cardiovascular disease may be at increased risk for VTE.

背景:众所周知,静脉血栓栓塞症(VTE)是脊柱手术后的一种并发症。由于许多颈椎病患者会因脊髓病变而导致严重的步态障碍,因此与其他脊柱疾病相比,颈椎病可能蕴含着更高的 VTE 风险。然而,迄今为止很少有研究主要关注颈椎手术。本调查旨在确定颈椎手术后 VTE 的发生率,并识别基于患者的风险因素:回顾性研究了连续接受颈椎手术的 341 名患者(男性 240 人,女性 101 人;平均年龄 68.1 岁)的医疗数据。采用逻辑回归模型研究了术后 VTE 的发生率、特征和风险因素:结果:在这项研究中,2.6% 的颈椎手术患者在术后出现了 VTE。在 VTE 组和非 VTE 组的比较中发现,年龄(79.6 岁 vs 67.7 岁,P < 0.01)、术后 1 周 D-二聚体水平(10.6 μg/mL vs 2.7 μg/mL,P < 0.01)和心血管疾病(44.4% vs 11.1%,P = 0.011)存在显著差异。多变量分析发现,术后 D-二聚体水平升高和心血管疾病与术后 VTE 显著相关,各自的几率分别为 1.54 和 9.52:颈椎手术术后 VTE 发生率为 2.6%。术后 D-二聚体水平升高且患有心血管疾病的患者发生 VTE 的风险可能会增加,因此可能需要额外观察:脊柱外科医生应考虑到术后 D-二聚体水平升高和心血管疾病患者可能会增加 VTE 风险:4:

Background: Interest in the correlation between the spinopelvic complex and its radiographic parameters in early total hip arthroplasty has been increasing. This study investigated whether radiological spinopelvic parameters are risk factors for early total hip replacement (THR) within 1 year of spinal fusion surgery. The primary research question focused on identifying specific spinopelvic changes that may lead to early THR.

Methods: We retrospectively analyzed patients who underwent lumbar spinal fusion between 2016 and 2021. The patients were divided into 2 groups: patients who underwent early THR (n = 35) and patients who did not (n = 213). Spinopelvic parameters, including pelvic incidence (PI), sacral slope (SS), pelvic tilt, lumbar lordosis, thoracolumbar kyphosis (TLK), sagittal vertical axis, and thoracic kyphosis (TK), were measured before and after surgery. The statistical analyses included inverse probability of treatment weighting, independent t tests, χ 2 tests, and logistic regression analyses.

Results: A total of 248 patients were included in the study. The pre- and postoperative TLK and TK angles were significantly smaller in the early THR group than in the late THR group. Increases in the PI and SS after surgery were significant risk factors. The use of interbody fusion techniques was associated with a higher rate of early THR. The difference in the PI minus lumbar lordosis before and after surgery was also significantly correlated with early THR.

Conclusions: Abnormal spinopelvic parameters, especially reduced TLK and TK angles and increased PI and SS, are risk factors for early THR.

Clinical relevance: Changes in spinopelvic parameters can lead to rapid hip joint destruction, which highlights the need for careful preoperative evaluation and postoperative monitoring of patients to prevent early THR.

Level of evidence: 3:

背景:人们对早期全髋关节置换术中脊柱骨盆复合体及其放射学参数之间的相关性越来越感兴趣。本研究调查了脊柱融合手术后 1 年内,放射学上的脊柱骨盆参数是否是早期全髋关节置换术(THR)的风险因素。研究的主要问题是确定可能导致早期全髋关节置换术的特定脊柱骨盆变化:我们对 2016 年至 2021 年间接受腰椎融合术的患者进行了回顾性分析。患者分为两组:接受早期 THR 的患者(n = 35)和未接受早期 THR 的患者(n = 213)。在手术前后测量了脊柱骨盆参数,包括骨盆内陷(PI)、骶骨斜度(SS)、骨盆倾斜、腰椎前凸、胸腰椎后凸(TLK)、矢状垂直轴和胸椎后凸(TK)。统计分析包括治疗加权逆概率、独立 t 检验、χ 2 检验和逻辑回归分析:研究共纳入 248 名患者。早期 THR 组的术前和术后 TLK 和 TK 角度明显小于晚期 THR 组。术后PI和SS的增加是重要的风险因素。使用椎间融合技术与较高的早期 THR 发生率相关。手术前后PI减去腰椎前凸的差异与早期THR也有显著相关性:结论:异常的脊柱骨盆参数,尤其是TLK和TK角度减小、PI和SS增大,是早期THR的风险因素:脊柱参数的变化可导致髋关节的快速破坏,因此需要对患者进行仔细的术前评估和术后监测,以预防早期髋关节置换术:3:
