经皮椎体成形术(PVP)作为治疗骨质疏松性椎体压缩骨折(OVCF)的重要手段,研究其不同穿刺入路具有重要意义。双侧椎弓根入路可使骨水泥在椎体内弥散更加均匀;单侧椎弓根入路具有出血少、透视次数少、时间短等优点;弯角椎弓根入路以单侧椎弓根入路进针,骨水泥在椎体内多点注射,同时保留了单侧椎弓根入路与双侧椎弓根入路的优点;横突-椎弓根入路骨性标志定位明确,穿刺成功率高,关节突损伤风险低;单侧后外上方入路、横突上缘椎体外侧壁入路和横突-椎弓根极外侧入路穿刺不受椎弓根约束,有利于骨水泥在椎体内均匀分布,为PVP提供了更加灵活和安全的选择;肋横突间椎弓根入路和前外侧入路在胸椎和颈椎PVP治疗中具有明显优势;Kambin三角入路通过经典手术入路区域进行穿刺,具有较好的应用价值。该文就PVP手术入路研究进展进行综述。  相似文献

Background

Patient-reported outcome measures (PROMs) are used to evaluate the outcome of total hip arthroplasty (THA). We determined the effect of surgical approach on PROMs after primary THA.

Methods

All primary THAs, with registered preoperative and 3 months postoperative PROMs were selected from the Dutch Arthroplasty Register. Based on surgical approach, 4 groups were discerned: (direct) anterior, anterolateral, direct lateral, and posterolateral approaches. The following PROMs were recorded: Hip disability and Osteoarthritis Outcome Score Physical function Short form (HOOS-PS); Oxford Hip Score; EQ-5D index score; EQ-5D thermometer; and Numeric Rating Scale measuring pain, both active and in rest. The difference between preoperative and postoperative scores was calculated (delta-PROM) and used as primary outcome measure. Multivariable linear regression analysis was performed for comparisons. Cohen's d was calculated as measure of effect size.

Results

All examined 4 approaches resulted in a significant increase of PROMs after primary THA in the Netherlands (n = 12,274). The anterior and posterolateral approaches were associated with significantly more improvement in HOOS-PS scores compared with the anterolateral and direct lateral approaches. Furthermore, the posterolateral and anterior approaches showed greater improvement on Numeric Rating Scale pain scores compared with the anterolateral approach. No relevant differences in delta-PROM were seen between the anterior and posterolateral surgical approaches.

Conclusion

Anterior and posterolateral surgical approaches showed more improvement in self-reported physical functioning (HOOS-PS) compared with anterolateral and direct lateral approaches in patients receiving a primary THA. However, clinical differences were only small.  相似文献

目的:比较经肌间隙入路和传统入路对腰椎融合手术患者的影响。方法:对2016年5月至2017年5月因腰椎间盘突出或MeyerdingⅡ度以内腰椎滑脱行2个节段以内腰椎融合手术治疗的70例患者进行回顾性分析。70例患者根据手术入路分为两组,肌间隙入路组35例,男18例,女17例,年龄(52±11)岁;传统入路组35例,男19例,女16例,年龄(51±14)岁。70例患者中包括腰椎间盘突出症38例,腰椎滑脱32例。记录两组患者的手术时间、术中出血量,术后引流量、腰腿痛VAS评分、外周血CK浓度以及MRI上多裂肌横截面积。结果:肌间隙入路组手术时间、术中出血量和术后引流量均少于传统入路组(P0.05)。术后7 d和3个月两组患者的VAS腰痛评分差异有统计学意义(P0.05);两组患者VAS腿痛评分,术后7 d差异无统计学意义(P0.05),术后3个月差异有统计学意义(P0.05)。术后1 d和3 d外周血CK浓度:肌间隙入路组分别为(400±103) U/L和(176±58) U/L,传统入路组分别为(598±57) U/L和(222±50) U/L,两组间差异有统计学意义(P0.05)。两组患者MRI上多裂肌横截面积:术前肌间隙入路组为(424±66) mm~2,传统入路组为(428±82)mm~2,组间差异无统计学意义(P=0.8);术后3个月肌间隙入路组为(347±73) mm~2,传统入路组为(239±78) mm~2,组间差异有统计学意义(P0.05)。结论:行腰椎融合手术,肌间隙入路与传统后正中入路相比,确实拥有手术时间短、对椎旁肌损伤小、术后腰腿痛缓解明显等优势,但在确定手术方案时,术者也应充分认识到Wiltse间隙在不同层面的解剖学差异可能对手术操作产生的影响。  相似文献

Background

The direct anterior approach for total hip arthroplasty (THA) has generated increased interest recently. The purpose of this study was to compare the duration to failure and reasons for revision of primary THA performed elsewhere and subsequently revised at our institution after the direct anterior vs other nonanterior surgical approaches to the hip.

Methods

All primary THAs performed elsewhere and referred to our institution for revision were divided into the direct anterior approach (30 cases) or nonanterior approach groups (100 cases, randomly selected from 453 cases) based on the original surgical approach. Because all primary direct anterior THAs were originally performed after 2004 to eliminate temporal bias, we identified a subset of the nonanterior group in which the primary THA was performed after 2004 (known as the recent nonanterior group, 100 cases, randomly selected from 169 available cases).

Results

The mean duration from primary to revision THA was 3.0 ± 2.7 years (direct anterior approach), 12.0 ± 8.8 years (nonanterior approach), and 3.6 ± 2.8 years (recent nonanterior), respectively. There was a significant difference in time to revision between the direct anterior and nonanterior approach groups (P < .001). Aseptic loosening of the stem was significantly more frequent with the direct anterior approach group (9/30, 30.0%) when compared with the nonanterior group (8/100, 8.0%, P = .007) and the recent nonanterior group (7/100, 7.0%, P = .002).

Conclusion

Revision of the femoral component for aseptic loosening is more commonly associated with the direct anterior approach in our referral practice.  相似文献

The restricted operative field, difficulty of obtaining proximal vascular control, and close relationship to important anatomic structures limit approaches to basilar apex aneurysms. We used a cadaveric model to compare three surgical transcavernous routes to the basilar apex in the neutral configuration. Five cadaveric heads were dissected and analyzed. Working areas and length of exposure provided by the transcavernous (TC) approach via pterional, orbitozygomatic, and temporopolar (TP) routes were measured along with assessment of anatomic variation for the basilar apex region. In the pterional TC and orbitozygomatic TC approaches, the mean length of exposure of the basilar artery measured 6.9 and 7.2 mm, respectively (p = NS). The mean length of exposure in a TP TC approach increased to 9.3 mm (p < 0.05). Compared with the pterional and orbitozygomatic approaches, the TP TC approach provided a larger peribasilar area of exposure ipsilaterally and contralaterally (p < 0.05). The multiplanar working area related to the TP TC approach was 77.7 and 69.5% wider than for the pterional TC and orbitozygomatic TC, respectively. For a basilar apex in the neutral position, the TP TC approach may be advantageous, providing a wider working area for the basilar apex region, improving maneuverability for clip application, fine visualization of perforators, and better proximal control.  相似文献

The microsurgical anatomy and related techniques of a modified anterolateral transthoracic approach to the thoracic disc space is presented. This procedure was performed on at least three thoracic levels of 12 cadavers within a few hours after death. Such an approach allows a safe decompression of the spinal cord and roots under full visual control. There is minimal risk to radiculome-dullary vessels, minimal osteoligamental resection, and no compromise of stability of the spinal column. Therefore, this procedure does not require surgical stabilization of the spinal column, postoperative bracing, or prolonged bed rest. The difference between this approach and anterolateral transthoracic, posterolateral, and transpedicular approaches is discussed.  相似文献

The surgical results of 18 cases of clival/upper cervical chordoma treated in the last decade via the endoscopic endonasal approach (EEA, 9 cases) and the transoral-transpalatal approach (TO-TPA, 9 cases) were compared. Each group showed the same incidence of subdural invasion, with 5 cases each. The superior (frontal base) and lateral surgical fields were wider by EEA, but the inferior view lower than the cranio-vertebral junction (CVJ) was wider by TO-TPA. Gross total removal was achieved in 3 cases in the EEA group, but in only 1 case in the TO-TPA group. Differences in radicality might be due to the extent of the lateral and subdural overview. However for large tumors extending below the CVJ, TO-TPA was the only viable approach for surgical removal. Surgical complications were higher in the EEA (4 cases) than the TO-TPA group (1 case), and were mainly caused by aggressive management of subdural invasion in the EEA group. Post-operative oral intake was earlier and the operative time was shorter in the EEA group. The surgical results were more radical and less invasive in the EEA group than the TO-TPA group. However in tumors extending below the CVJ, the surgical field in EEA was limited, indicating the need to use the transoral route or a combination of routes. A higher complication rate following subdural management was a negative factor that requires improvement in the EEA group and two-staged EEA followed by a transcranial approach may be considered for the cases with subdural invasion.  相似文献
