Background

Remote monitoring has been correlated to reduced acute care usage (emergency department (ED)) in cardiovascular, diabetes and COVID domains. Correspondingly, the use of smart implantable devices (SID) in total knee arthroplasty (TKA) may lead to reduced acute care usage in orthopedics.

Methods

Retrospective claims data from a nationally representative, third-party claims aggregator were analyzed for ED and hospital admission incidence and cumulative 90-day costs. Patients who received an SID were identified and matched 1:2 with patients who received a traditional knee prosthesis. A subgroup of patients with complete longitudinal claims data for days 91–365 were analyzed for cost comparisons. Chi-squared tests were used to compare acute care incidence and Wilcoxon rank sum tests were used to compare costs.

Results

The analysis included 1621 patients with SID knees (1709 TKAs) and 3041 patients (3418 TKAs) implanted with traditional knees. Cumulative incidence of ED visit (SID: 11.4 %; control: 15.6 %), hospital admission (SID: 6.0 %; control: 8.8 %), or any acute care (ED or hospital admission) (SID: 14.1 %; control: 19.2 %) was significantly lower in the SID group (p < 0.05). Median total cost of all healthcare services from the day after surgery to day 90 was significantly lower in the SID group ($3747) than the controls ($5629), representing 61 % of the cost of control patients. SID patients also had lower costs during day 91–365 ($5322 and $8,454, respectively).

Conclusion

Use of SIDs in primary TKA was associated with fewer ED visits and hospital admissions, as well as lower 90-day total healthcare costs. These cost reductions reflect both a lower incidence of unplanned care and lower costs per patient. These findings support the potential of implant-derived recovery data to enhance care coordination, align postoperative management with patient expectations, increase patient confidence in their health status and reduce the burden of post-TKA acute care.
远程监测与减少心血管、糖尿病和COVID领域的急诊(急诊科)使用相关。相应地,在全膝关节置换术(TKA)中使用智能植入式设备(SID)可能会减少骨科的急性护理使用。方法回顾性分析来自全国代表性的第三方索赔汇总器的索赔数据,包括急症和住院发生率以及累计90天费用。接受SID的患者被识别并与接受传统膝关节假体的患者进行1:2的匹配。对91-365天完整的纵向索赔数据的患者亚组进行成本比较分析。用卡方检验比较急症发生率,用Wilcoxon秩和检验比较费用。结果共纳入1621例SID膝关节(1709例tka)和3041例传统膝关节(3418例tka)。SID组急症就诊(SID: 11.4%,对照组:15.6%)、住院(SID: 6.0%,对照组:8.8%)或任何急症(ED或住院)(SID: 14.1%,对照组:19.2%)的累积发生率均显著低于对照组(p < 0.05)。SID组从术后一天到第90天的所有医疗保健服务的中位数总成本(3747美元)显著低于对照组(5629美元),占对照组患者成本的61%。SID患者在第91-365天的费用也较低(分别为5322美元和8454美元)。结论:在原发性TKA中使用SIDs与较少的ED就诊和住院次数以及较低的90天总医疗费用相关。这些费用的减少既反映了计划外护理的发生率降低,也反映了每位患者的费用降低。这些发现支持种植体来源的恢复数据的潜力,以加强护理协调,使术后管理与患者期望保持一致,增加患者对其健康状况的信心,并减轻tka后急性护理的负担。

Design-dependent associations between quadriceps strength and sagittal knee biomechanics after posterior-stabilized total knee arthroplasty: A 3D motion analysis study 后稳定全膝关节置换术后股四头肌力量和矢状膝关节生物力学之间的设计依赖关系:一项3D运动分析研究

Purpose

Single-radius (SR) and multi-radius (MR) femoral components are widely used in posterior-stabilized total knee arthroplasty (TKA). While previous studies have compared these designs primarily using clinical outcomes or basic kinematics, the relationship between quadriceps strength and dynamic sagittal-plane knee biomechanics remains insufficiently understood.

Methods

This prospective exploratory cohort study included 31 posterior-stabilized TKAs (SR: 16 knees; MR: 15 knees). Patients were evaluated at 6 months and 1 year postoperatively. Knee extension strength was measured using a handheld dynamometer. Sagittal-plane biomechanics during level walking, stair ascent, and stair descent were assessed using three-dimensional motion capture. External knee flexion moment (KFM) and KFM impulse were calculated. Associations between quadriceps strength and sagittal-plane biomechanical variables were analyzed using Spearman correlation coefficients.

Results

No significant between-group differences were observed in demographics or clinical activity levels. In the SR group, no significant associations were identified between quadriceps strength and sagittal-plane biomechanical variables at any postoperative time point. In contrast, the MR group demonstrated a moderate positive correlation between knee extensor strength and stair-descent knee flexion moment (KFM) impulse at 6 months postoperatively (r = 0.498, p < 0.05), which was not observed at 1 year postoperatively. During stair ascent, a significant positive correlation between knee extensor strength and the first peak KFM was observed in the MR group at 1 year (r = 0.606, p < 0.05).

Conclusions

This exploratory study demonstrated design-dependent associations between quadriceps strength and sagittal-plane knee biomechanics after posterior-stabilized TKA. While no significant between-group differences were observed in clinical or absolute biomechanical outcomes, task- and time-dependent strength–biomechanics associations were identified in the MR group, whereas no such associations were observed in the SR group, suggesting potential clinical relevance in patients with delayed quadriceps recovery.
目的单桡骨(SR)和多桡骨(MR)股骨假体广泛应用于后稳定全膝关节置换术(TKA)。虽然先前的研究主要通过临床结果或基本运动学来比较这些设计,但股四头肌力量和动态矢状面膝关节生物力学之间的关系仍然没有得到充分的了解。方法本前瞻性探索性队列研究纳入31例后稳定tka患者(SR: 16膝;MR: 15膝)。分别于术后6个月和1年对患者进行评估。使用手持式测力仪测量膝关节伸展强度。使用三维运动捕捉技术评估水平行走、楼梯上升和楼梯下降时的矢状面生物力学。计算膝关节外屈力矩(KFM)和KFM冲量。使用Spearman相关系数分析股四头肌力量与矢状面生物力学变量之间的关系。结果两组在人口统计学和临床活动水平上无显著差异。在SR组中,在任何术后时间点,股四头肌力量和矢状面生物力学变量之间没有明显的关联。相比之下,MR组在术后6个月时膝关节伸肌强度与下楼梯膝关节屈曲力矩(KFM)脉冲呈中度正相关(r = 0.498, p < 0.05),而在术后1年未观察到这种正相关。在爬楼梯过程中,MR组1年时膝关节伸肌强度与KFM第一次峰值呈显著正相关(r = 0.606, p < 0.05)。结论:本探索性研究证实了后稳定TKA后股四头肌力量与膝关节矢状面生物力学之间的设计依赖性关联。虽然在临床或绝对生物力学结果方面没有观察到组间的显著差异,但在MR组中发现了任务和时间依赖的力量-生物力学关联,而在SR组中没有观察到这种关联,这表明在股四头肌延迟恢复患者中存在潜在的临床相关性。

Objective

To examine outcomes of femoral neck fractures (FNFs) in non-geriatric adults treated with the Femoral Neck System (FNS; DePuy Synthes, Warsaw, IN) compared to three other fixation techniques.

Methods

This was a retrospective study in two Level I Trauma Centers (2019–2024) in adults 18–50 years old with FNFs (AO/OTA 31) that underwent surgical fixation. Patients were classified by fixation method: femoral neck system (FNS), dynamic hip screw (DHS), cephalomedullary nail (CMN) device and cannulated screws (CS). Outcomes compared between groups included: rates of reoperation, union, hardware failure, avascular necrosis (AVN), conversion to total hip arthroplasty (THA), operative time, intraoperative radiation exposure, surgical site infection (SSI) and length of stay (LOS).

Results

A total of 95 patients were included (FNS n = 27; DHS n = 15; CMN n = 15; CS n = 38). The majority of the patients were male (64.2 %), with an average age of 32.5 years and follow up time of 363 days. While being used predominantly for displaced fractures (66.7 %, p = 0.001), the FNS had significantly lower rates of hardware failure (74.1 %; p = 0.046), AVN (0 %, p = 0.034) and THA conversion (0 %, p = 0.029). CS had the highest union rates (89.5 %; p = 0.046), lowest reoperation rates (13.2 %; p = 0.030) and were used primarily for non-displaced fractures (63.2 %, p = 0.001). There were no differences among groups in surgical time (p = 0.191), or LOS (p = 0.592). A sub-analysis comparing reoperation rates after closed reduction showed that successful closed reduction was associated with not requiring reoperation (40.5 % vs 14.3 %; p = 0.026).

Conclusion

Fixation of FNFs in young adults with the FNS has lower rates of AVN, hardware failure and THA conversion compared to other fixation methods. Fixation with screws has the highest union rate and lowest reoperation rate in this demographic. Fixation of FNFs with the FNS has similar if not better outcomes when compared to other fixation methods. However, surgical factors such as fracture displacement and closed reduction may have influenced outcomes and require further study.

Background

Inadequate treatment of posterior tibial plateau fractures can cause instability, yet no agreement exists regarding the optimal surgical approach for achieving favorable outcomes. Hence, the aim of this study is to assess and compare the postoperative outcomes of different posterior surgical techniques, including reverse L-shape, S-shaped, posterior medial, extended posterolateral, and posterolateral prone approaches.

Methods

To evaluate the efficacy of surgical approaches, we searched databases such as PubMed, Embase, Web of Science, The Cochrane Library, and Scopus. Studies published before October 26th, 2022 were included, and we followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The study's outcomes comprised complications, infections, range of motion (ROM), operation time, and functional scores, and p-values <0.05 were considered significant. To conduct the meta-analysis, we utilized the R software.

Results

We included 8 studies with 104 patients. The extended posterolateral approach reduced incidence of complications and improved ROM, while the posterolateral prone approach reduced ROM. Conversely, the S-shaped approach was linked to lower HSS scores. No significant differences were found in infection rates or operative time among the various surgical approaches.

Conclusions

The extended posterolateral approach was associated with a lower incidence of complications and greater ROM compared to other surgical approaches. In contrast, the S-shaped approach was linked to lower HSS scores, and the posterolateral prone approach was associated with reduced ROM. These findings suggest that further prospective studies are necessary to establish the optimal surgical approach for posterior tibial plateau fractures.
背景:胫骨后平台骨折的治疗不充分会导致不稳定,但对于获得良好结果的最佳手术方法尚无一致意见。因此,本研究的目的是评估和比较不同后路手术技术的术后结果,包括反l型入路、s型入路、后内侧入路、扩展后外侧入路和后外侧俯卧入路。方法为了评估手术入路的疗效,我们检索PubMed、Embase、Web of Science、the Cochrane Library、Scopus等数据库。纳入了2022年10月26日之前发表的研究,我们遵循了系统评价和荟萃分析(PRISMA)指南的首选报告项目。研究结果包括并发症、感染、活动范围(ROM)、手术时间和功能评分,p值<;0.05认为显著。为了进行meta分析,我们使用R软件。结果纳入8项研究,共104例患者。延长后外侧入路可减少并发症发生率并改善ROM,而后外侧俯卧入路可减少ROM。相反,s形入路与较低的HSS评分有关。不同手术入路的感染率和手术时间无显著差异。结论与其他手术入路相比,扩展后外侧入路并发症发生率较低,ROM较大。相反,s形入路与HSS评分较低有关,后外侧俯位入路与ROM降低有关。这些发现表明,需要进一步的前瞻性研究来确定胫骨后平台骨折的最佳手术入路。

Despite extensive research on osteoporosis therapies, systematic analysis of knowledge evolution and translational bottlenecks remains unexplored. This study presents the multidimensional bibliometric analysis of 10,247 publications (2015–2024) to decode paradigm shifts in osteoporosis therapeutics. Using CiteSpace and VOSviewer for bibliometric and visualization analyses, we observed a notable increase in annual publications, peaking in 2022. China and the United States led in research output, while European countries demonstrated higher citation impact.

Introduction

Hip arthroscopy (HA) is increasingly used to treat femoroacetabular impingement (FAI) and labral tears, with growing interest in the role of socioeconomic factors on postoperative outcomes. Prior literature suggests socioeconomic deprivation may worsen patient-reported outcomes (PROMs), but findings regarding the Area Deprivation Index (ADI) and urbanization status remain inconsistent. This study aimed to evaluate the difference in PROMs after HA secondary to symptomatic FAI and hip labral tears based on the residential urbanization status, demographic variables, and Area Deprivation Index (ADI) values of patients in our single-center cohort

Methods

A single-institution retrospective review was conducted on 86 patients who underwent HA between 2014 and 2023. Patients were categorized as urban or rural based on U.S. Census data and assigned national/state ADI scores based on their residential addresses. PROMs (mHHS, HOS-ADL, HOS-Sport, NAHS) were collected via telephone survey at ≥1 year postoperatively. Statistical comparisons and multivariable regression analyses were used to assess the impact of demographic variables and ADI on PROMs.

Results

There were no significant differences in PROMs between urban and rural patients. However, regression analysis revealed that national ADI and age were significantly negatively correlated with all PROMs (p < 0.05). Older age and higher ADI independently predicted worse postoperative outcomes. Interaction effects, such as age × BMI or age × ADI, also negatively influenced certain PROMs. Race and surgical indication showed limited interaction effects.

Conclusion

While urbanization status did not impact outcomes, higher socioeconomic deprivation (as measured by national ADI) and increased age were associated with significantly worse PROMs after HA at 1-year follow-up. These findings suggest that neighborhood-level socioeconomic disadvantage plays a more critical role than urban-rural classification in influencing recovery. Strategies aimed at addressing social determinants of health may improve HA outcomes, particularly in socioeconomically disadvantaged populations.
髋关节镜(HA)越来越多地用于治疗股髋臼撞击(FAI)和唇部撕裂,社会经济因素对术后结果的影响越来越受到关注。先前的文献表明,社会经济剥夺可能会使患者报告的预后(PROMs)恶化,但关于区域剥夺指数(ADI)和城市化状况的研究结果仍不一致。本研究旨在基于居住城市化状况、人口统计学变量和单中心队列患者的区域剥夺指数(ADI)值,评估HA并发症状性FAI和髋关节唇裂后PROMs的差异。方法对2014年至2023年期间接受HA的86例患者进行单机构回顾性分析。根据美国人口普查数据将患者分为城市或农村,并根据其居住地址分配国家/州的ADI分数。术后≥1年通过电话调查收集数据(mHHS、HOS-ADL、HOS-Sport、NAHS)。采用统计比较和多变量回归分析来评估人口统计学变量和ADI对PROMs的影响。结果城乡患者PROMs差异无统计学意义。然而,回归分析显示,国家ADI和年龄与所有PROMs呈显著负相关(p < 0.05)。年龄较大和较高的ADI独立预测较差的术后预后。相互作用效应,如年龄× BMI或年龄× ADI,也会对某些prom产生负面影响。种族和手术指征的相互作用有限。结论:虽然城市化状况不影响结果,但在1年随访中,较高的社会经济剥夺(以国家ADI衡量)和年龄增加与HA后显著恶化的PROMs相关。这些发现表明,社区水平的社会经济劣势比城乡分类对恢复的影响更为关键。旨在解决健康的社会决定因素的战略可以改善卫生保健的结果,特别是在社会经济上处于不利地位的人群中。

Background

Peroneal tendon disorders span tendinopathy, tenosynovitis, intrasheath subluxation, stenosis, and tears, and may be challenging to diagnose accurately with clinical examination and MRI alone. Peroneal tendoscopy offers a minimally invasive, diagnostic–therapeutic option. We systematically reviewed clinical indications, intraoperative findings, procedures, imaging accuracy, complications, and patient-reported outcomes following peroneal tendoscopy.

Methods

Eight studies (190 patients; 195 ankles) were reviewed. Data on demographics, indications, procedures, PROMs, return to sport (RTS), complications/failures, and imaging–tendoscopy agreement were extracted and pooled when constructs aligned. Random-effects meta-analyses generated pooled means or proportions with 95 % CIs (Hartung–Knapp adjustment). Where applicable, diagnostic performance of preoperative assessment was compared with tendoscopy as reference.

Results

Across 190 patients (195 ankles), pooled mean age was 32 years (95 % CI 25.0–39.0), follow-up 30.3 months (95 % CI 20.8–39.8); 71 % of ankles had traumatic aetiologies. Indications were broad, with recurrent subluxation/dislocation, intrasheath subluxation, and refractory lateral ankle pain common. Frequently performed procedures included synovectomy/debridement (94 ankles), groove deepening (34 ankles), excision of space occupying lesions (65 ankles; predominantly low-lying muscle bellies [LLMB] and peroneus quartus), tendon repair/tubularization (23 ankles), and tendoscopic retinacular repair (14 ankles). Six studies reported validated PROMS with four reporting AOFAS suitable for pooling. Postoperative AOFAS averaged 96.6 (95 % CI 94.3–99.0) with a pooled mean gain of +19.8 (95 % CI 18.5–21.2); JSSF, FAOS and SF-12 improved significantly. RTS occurred at a pooled 13.3 weeks (95 % CI 10.6–16.0), with RTS of 12.2 ± 0.6 weeks after tendoscopic retinacular stabilization and 14.8 ± 2.0 weeks after groove deepening. Overall complications were 7.6 % (13 events) and mainly consisted of persistent ankle pain and minor wound issues. Failure rate was 1.5 % and two revision surgeries (1.0 %) were reported. Diagnostic agreement was high at the aggregate level (MRI overall sensitivity 0.90, specificity 0.72), but lesion-level performance varied: MRI was strong for tears and tenosynovitis, weaker for stenosis. Composite preoperative diagnosis in a large series showed high specificity (0.97) but only moderate sensitivity (0.76), with LLMB frequently under-recognized preoperatively.

Conclusions

Peroneal tendoscopy provides meaningful functional gains, timely RTS, and a low adverse-event burden across a wide indication spectrum, and it complements imaging by clarifying dynamic/space-conflict pathology. Longer, prospective comparative studies are warranted.
腓肌腱疾病包括肌腱病、腱鞘炎、腱鞘内半脱位、狭窄和撕裂,仅凭临床检查和MRI可能难以准确诊断。腓肌腱镜检查提供了一种微创、诊断治疗的选择。我们系统地回顾了腓肌腱镜检查后的临床适应症、术中发现、手术、成像准确性、并发症和患者报告的结果。方法回顾性分析8项研究(190例患者,195例踝关节)。当结构对齐时,提取和汇总有关人口统计学、适应症、手术、prom、恢复运动(RTS)、并发症/失败和成像-肌腱镜检查一致性的数据。随机效应荟萃分析产生95% ci的汇总平均值或比例(Hartung-Knapp校正)。在适用的情况下,将术前评估的诊断效果与肌腱镜检查进行比较作为参考。结果190例患者(195踝关节),合并平均年龄32岁(95% CI 25.0 ~ 39.0),随访30.3个月(95% CI 20.8 ~ 39.8);71%的踝关节有外伤性病因。适应症广泛,复发性半脱位/脱位,鞘内半脱位,常见的难治性踝关节外侧疼痛。常用的手术包括滑膜切除术/清创(94个踝关节),沟加深(34个踝关节),占位性病变切除(65个踝关节,主要是低处肌肉腹部[LLMB]和腓骨四角肌),肌腱修复/管化(23个踝关节),肌腱镜下支持带修复(14个踝关节)。6项研究报告了验证的PROMS,其中4项报告了适合合并的AOFAS。术后AOFAS平均为96.6 (95% CI 94.3-99.0),合并平均增益为+19.8 (95% CI 18.5-21.2);JSSF、FAOS和SF-12显著改善。RTS发生在13.3周(95% CI 10.6-16.0),其中肌腱镜下支持带稳定后的RTS为12.2±0.6周,沟加深后的RTS为14.8±2.0周。总并发症为7.6%(13次),主要包括持续的踝关节疼痛和轻微的伤口问题。失败率为1.5%,2例翻修手术(1.0%)。总体水平的诊断一致性很高(MRI总敏感性0.90,特异性0.72),但病变水平表现不同:MRI对撕裂和腱鞘炎的诊断较强,对狭窄的诊断较弱。术前综合诊断在大序列中显示出高特异性(0.97),但只有中等敏感性(0.76),LLMB在术前经常被低估。结论肌腱镜检查在广泛的适应症范围内提供了有意义的功能获益,及时的RTS和低不良事件负担,并通过澄清动态/空间冲突病理补充了影像学。更长的前瞻性比较研究是有必要的。

IF 1.5 Q3 ORTHOPEDICS Pub Date : 2026-04-01 Epub Date: 2025-12-31 DOI: 10.1016/j.jor.2025.12.068

Background

Hip abductor weakness is common after proximal femoral fracture and may contribute to gait instability. The influence of postoperative hip alignment on early recovery of hip abductor strength during inpatient rehabilitation after surgery remains unclear.

Objective

To examine longitudinal changes in hip abductor strength and identify factors associated with the operated-to-non-operated hip abductor strength ratio at discharge, focusing on surgical procedure and radiographic alignment.

Methods

This retrospective observational cohort study enrolled 64 patients transferred to a rehabilitation hospital after proximal femoral fracture surgery (34 femoral neck fractures treated with hemiarthroplasty; 30 intertrochanteric fractures treated with cephalomedullary nailing). Hip abductor strength was measured using a handheld dynamometer at rehabilitation admission and discharge and normalized by body weight. Radiographic parameters were measured on supine anteroposterior pelvic radiographs; side-to-side differences (operated minus non-operated) were calculated for the neck–shaft angle, hip center of rotation, femoral offset, and trochanteric height. Multivariable linear regression (ANCOVA-type) was performed with the discharge strength ratio as the dependent variable and the admission strength ratio as an adjustment factor.

Results

Hip abductor strength improved on both sides (p < 0.001). The operated side increased from 1.04 ± 0.5 to 1.8 ± 0.7 N/kg and the non-operated side from 1.6 ± 0.6 to 2.3 ± 0.8 N/kg; the operated-to-non-operated ratio improved from 62.7 % to 72.9 %. In the adjusted model (R2 = 0.325), cephalomedullary nailing (vs hemiarthroplasty) was associated with a higher discharge strength ratio (B = 0.114, p = 0.027). A greater neck–shaft angle difference was also associated with a higher discharge strength ratio (B = 0.0073 per degree, p = 0.011). The admission strength ratio remained a significant predictor (B = 0.245, p = 0.002).

Conclusions

Early recovery of the hip abductor strength ratio after proximal femoral fracture was associated with surgical procedure and postoperative neck–shaft angle asymmetry, independent of baseline strength ratio. Postoperative radiographic alignment may aid in stratifying recovery and tailoring rehabilitation, although causal inference is limited.
背景:股骨近端骨折后髋关节外展肌无力很常见,可能导致步态不稳定。术后髋关节对准对术后住院康复期间髋关节外展肌力早期恢复的影响尚不清楚。目的探讨髋关节外展肌力量的纵向变化,并确定与出院时手术与非手术髋关节外展肌力量比相关的因素,重点是手术方式和x线对准。方法回顾性观察队列研究纳入64例股骨近端骨折术后转至康复医院的患者,其中34例股骨颈骨折采用半关节置换术治疗,30例股骨粗隆间骨折采用头髓内钉治疗。在康复入院和出院时使用手持式测力仪测量髋关节外展肌力,并按体重归一化。在仰卧位骨盆正位x线片上测量影像学参数;计算颈轴角、髋关节旋转中心、股骨偏移量和粗隆高度的侧对侧差异(手术减去非手术)。以出料强度比为因变量,进料强度比为调节因子,进行ancova型多变量线性回归分析。结果双侧外展肌力量均有改善(p < 0.001)。手术侧从1.04±0.5 N/kg增加到1.8±0.7 N/kg,非手术侧从1.6±0.6 N/kg增加到2.3±0.8 N/kg;运行与非运行比率从62.7%提高到72.9%。在调整后的模型中(R2 = 0.325),头髓内钉(与半关节置换术相比)与较高的出院强度比相关(B = 0.114, p = 0.027)。较大的颈轴角差也与较高的放电强度比相关(B = 0.0073 /度,p = 0.011)。入院强度比仍然是一个显著的预测因子(B = 0.245, p = 0.002)。结论股骨近端骨折后髋外展肌力量比的早期恢复与手术方式和术后颈轴角不对称有关,与基线力量比无关。术后x线对准可能有助于分层恢复和定制康复,尽管因果推理有限。

Background

Sacral chordomas are rare malignant tumors arising from notochordal remnants that can be identified incidentally or present with sacral pain. Although surgical resection is the accepted standard treatment, some patients forgo surgery due to associated morbidity and complications. Nonoperative alternatives, including radiotherapies, have emerged, but literature on their outcomes remains scarce. The purpose of this study was to evaluate the outcomes of nonoperative management of sacral chordomas.

Methods

We conducted a systematic review of the literature utilizing PubMed. Search keywords included “nonoperative treatment,” “sacral chordomas,” “radiotherapy,” and “functional outcomes.” Studies involving sacral chordoma patients who underwent nonoperative treatment were included; patients with surgical treatment and hybrid therapies that included surgery were excluded from the analysis.

Results

Eleven clinical studies on nonoperative management of sacral chordomas with 52 patients aged between 35 and 85 years (mean = 62.8) were identified. Males were affected at higher rates than females (73.1 % vs 26.9 %). S1 (15.4 %) and S2 (25 %) were the most affected spinal segments. CT-guided biopsy was the most common method of tumor diagnosis (82.7 %). Carbon ion radiotherapy (CIRT) and proton beam therapy were the most common treatment methods, with 57.7 % of patients reporting recurrence-free survival at a mean follow-up of 24 months.

Conclusion

Nonoperative management of sacral chordomas shows promising outcomes for patients who are not candidates for surgery. Although recurrence remains a risk, nonoperative management may offer meaningful functional preservation and local disease control.
背景:骶脊索瘤是一种罕见的恶性肿瘤,起源于脊索残余,可偶然发现或伴有骶痛。虽然手术切除是公认的标准治疗方法,但由于相关的发病率和并发症,一些患者放弃手术。包括放射治疗在内的非手术替代疗法已经出现,但关于其结果的文献仍然很少。本研究的目的是评估非手术治疗骶脊索瘤的结果。方法利用PubMed对相关文献进行系统综述。搜索关键词包括“非手术治疗”、“骶脊索瘤”、“放疗”和“功能结果”。包括接受非手术治疗的骶脊索瘤患者的研究;手术治疗和混合治疗包括手术的患者被排除在分析之外。结果对52例35 ~ 85岁的骶脊索瘤患者进行非手术治疗的临床研究,平均62.8岁。男性受影响的比例高于女性(73.1% vs 26.9%)。S1(15.4%)和S2(25%)是受影响最大的脊柱节段。ct引导下活检是最常见的肿瘤诊断方法(82.7%)。碳离子放射治疗(CIRT)和质子束治疗是最常见的治疗方法,平均随访24个月,57.7%的患者报告无复发生存。结论非手术治疗骶脊索瘤对不需要手术治疗的患者有较好的疗效。虽然复发仍有风险,但非手术治疗可能提供有意义的功能保留和局部疾病控制。

Background

The management of massive rotator cuff tears (MRCTs) without glenohumeral arthritis presents a significant clinical challenge. The choice between primary arthroscopic rotator cuff repair (RCR) and reverse shoulder arthroplasty (RSA) remains controversial, with limited comparative data on patient-centered outcomes.

Purpose

To compare functional outcomes, patient-priority outcome domains, and complication rates between primary arthroscopic RCR and primary RSA in patients with massive rotator cuff tears.

Methods

This retrospective cohort study included 70 patients (36 RCR, 34 RSA) treated between 2022-2024 with minimum 12-month follow-up (mean 24.3 ± 6.7 months). Patient demographics, preoperative imaging findings (Goutallier fatty infiltration, Patte retraction, Hamada staging), traditional functional scores (ASES, Constant, DASH, VAS), range of motion, and patient-priority outcome domains (pain-free sleep, overhead activity, internal rotation tasks, heavy work capacity, return to sports) were compared using appropriate statistical methods.

Results

RCR patients were significantly younger (64.8 ± 7.2 vs. 72.1 ± 6.9 years, p < 0.001) with lower Goutallier grades (Grade≥3: 44.7% vs. 94.4%, p < 0.001). Both groups achieved significant pain reduction and functional improvement. At final follow-up, RCR demonstrated superior active flexion (146.3° ± 24.8° vs. 117.2° ± 27.3°, p < 0.001), internal rotation (L3 vs. S1 level, p = 0.001), and ASES scores (79.2 ± 23.4 vs. 69.8 ± 26.1, p = 0.042). RCR showed significant advantages in patient-priority domains including overhead activity (3.2 ± 0.8 vs. 2.6 ± 0.9, p = 0.002), internal rotation tasks (3.3 ± 0.7 vs. 2.2 ± 1.0, p < 0.001), and return to sports (2.6 ± 1.1 vs. 1.8 ± 0.9, p = 0.001). Complication rates were similar (11.1% vs. 8.8%, p = 0.734).

Conclusion

In younger, active patients with adequate tissue quality, primary arthroscopic RCR provides superior range of motion and patient-centered functional outcomes. RSA remains a reliable option for elderly patients with advanced fatty infiltration and chronic pseudoparalysis. Careful evaluation of these factors is critical for optimal patient selection.
背景:无肩关节关节炎的大量肩袖撕裂(mrct)的处理是一个重大的临床挑战。初级关节镜下肩袖修复(RCR)和反向肩关节置换术(RSA)之间的选择仍然存在争议,以患者为中心的结果的比较数据有限。目的比较原发性关节镜下RCR和原发性RSA对大面积肩袖撕裂患者的功能结局、患者优先考虑的结果域和并发症发生率。方法回顾性队列研究纳入70例患者(RCR 36例,RSA 34例),随访时间为2022-2024年,随访时间最短12个月(平均24.3±6.7个月)。采用适当的统计方法比较患者人口统计学特征、术前影像学表现(Goutallier脂肪浸润、Patte回缩、Hamada分期)、传统功能评分(ASES、Constant、DASH、VAS)、运动范围和患者优先考虑的结果域(无痛睡眠、头顶活动、内部旋转任务、繁重工作能力、重返运动)。结果rcr患者明显年轻化(64.8±7.2岁比72.1±6.9岁,p < 0.001), Goutallier评分较低(≥3级:44.7%比94.4%,p < 0.001)。两组均获得显著的疼痛减轻和功能改善。在最后的随访中,RCR显示了更好的主动屈曲(146.3°±24.8°vs. 117.2°±27.3°,p < 0.001),内旋(L3 vs. S1水平,p = 0.001)和asas评分(79.2±23.4 vs. 69.8±26.1,p = 0.042)。RCR在患者优先领域显示出显著优势,包括头顶活动(3.2±0.8 vs. 2.6±0.9,p = 0.002)、内旋任务(3.3±0.7 vs. 2.2±1.0,p < 0.001)和重返运动(2.6±1.1 vs. 1.8±0.9,p = 0.001)。并发症发生率相似(11.1% vs 8.8%, p = 0.734)。结论在年轻、活跃、组织质量良好的患者中,初级关节镜下RCR提供了更好的活动范围和以患者为中心的功能结果。对于晚期脂肪浸润和慢性假性麻痹的老年患者,RSA仍然是一个可靠的选择。仔细评估这些因素对于最佳患者选择至关重要。
