3D打印技术在复杂胫骨平台骨折手术中的应用研究

目的 探讨应用3D打印技术辅助手术治疗复杂胫骨平台骨折的临床效果。方法 选取2014年1月至2017年3月我院收治的复杂胫骨平台骨折病人29例，随机分为观察组（15例）及对照组（14例）进行队列分析比较。观察组胫骨平台经Mimics软件处理，3D打印成1∶1骨折模型，将骨折及健侧模型进行镜像对比，设定手术方案；对照组常规参照术前X线片及CT制定修复方案。术后观察并对两组的手术时间、出血量、术后关节塌陷纠正情况、术后12个月膝关节Rasmussen功能评分进行比较。结果 本研究29例病人的随防时间为（12.55±2.46）个月。观察组的手术时间、出血量明显小于对照组，术后关节塌陷纠正情况优于对照组，差异均有统计学意义（t=2.297，P=0.029；t=2.674，P=0.013；t=2.658，P=0.020）；术后12个月两组膝关节Rasmussen评分差异无统计学意义（P＞0.05）；观察组膝关节功能恢复优良率（93.33%）高于对照组（78.57%）。结论 针对复杂胫骨平台骨折，应用3D打印技术制作骨折模型，通过模拟手术操作可以有效缩短手术时间，减少术中出血，纠正关节面塌陷程度。     

Routine postoperative radiographs after tibia plateau fixation have minimal impact on patient care

IntroductionCommon practice in orthopedic surgery is to obtain postoperative radiographs to evaluate for healing or complications. Images obtained in the post-anesthesia care unit (PACU) have not been shown to positively impact patient care. This study plans to evaluate the clinical utility and cost-effectiveness of PACU postoperative radiographs following tibial plateau open reduction and internal fixation (ORIF).MethodsData from 211 patients who underwent a tibial plateau ORIF over a 5-year period at a single institution were retrospectively reviewed to determine if a patient received a postoperative radiograph in the PACU. Radiograph and clinical notes were reviewed to determine if postoperative radiograph resulted in management changes. Radiograph charges were calculated using CPT codes.ResultsA total of 142 of 211 patients (67.3%) who underwent tibial plateau ORIF received a postoperative radiograph while in the PACU. The majority of the radiographs had normal findings (88.7%). Of the 142 patients with postoperative imaging, subsequent management changes occurred for only one patient (0.7%). In this case, an incidental foot fracture was found which resulted in further CT imaging to assess the fracture. Other abnormal radiograph readings (11.3%) were generally due to incidental, chronic findings that did not require management changes. The average postoperative radiograph cost was $433.55 per patient, totaling $91,480 for 142 patients over a 5-year period.ConclusionsRoutine postoperative radiographs following tibial plateau ORIF resulted in minimal management change patients in this series. The substantial cost of postoperative radiographs yielding little clinical utility suggests the use of routine PACU imaging following tibial plateau ORIF should be discontinued. Imaging would only be indicated in situations where intraoperative complications are suspected, thus reducing unnecessary imaging and patient cost.     

胫骨平台后外侧柱骨折手术患者发生切口感染的手术室相关因素及对策分析

目的探讨胫骨平台后外侧柱骨折手术患者发生切口感染的手术室相关因素及对策分析。方法选择2015年1月～2018年6月在我院治疗的胫骨平台后外侧柱骨折的患者383例的临床资料进行回顾性分析,根据术后是否发生切口感染分为感染组(n=36)与非感染组(n=347)。统计切口病原菌分布情况,分析影响患者术后切口感染手术室相关因素,并探讨预防对策。结果 36例患者共分离出病原菌48株。革兰阳性菌比例最高,占66.7%,其中金黄色葡萄球菌构成比最高,其次为表皮葡萄球菌。革兰阴性菌中铜绿假单胞菌是主要菌株,分离出1例真菌。多因素分析结果显示:急诊手术、有参观人员、接台手术、手术时间≥3 h是胫骨平台后外侧柱骨折患者术后切口感染的独立危险因素,而层流室是保护因素(P0.05)。结论胫骨平台后外侧柱骨折手术患者术后切口感染的手术室相关因素包括急诊手术、有参观人员、接台手术、手术时间≥3 h,应加强手术室相关管理,采取必要的措施,降低术后切口感染风险。     

关节镜引导下复位内固定治疗胫骨平台骨折的疗效和对患者膝关节功能恢复及生活质量的影响

目的研究关节镜引导下复位内固定对胫骨平台骨折(FTP)患者的疗效和膝关节功能恢复及生活质量的影响。方法选取该院2016年8月-2018年3月收治的FTP患者104例,采用随机数字法将其分为观察组和对照组,每组52例。观察组行膝关节镜辅助切开复位内固定术,对照组患者行传统切开复位内固定术。比较两组患者的手术指标(切口长度、出血量、手术用时、术后引流量及下床时间)、骨生化指标[Ca~(2+)、降钙素(CT)、骨形态发生蛋白(BMP)和骨特异性碱性磷酸酶(NBAP)]、治疗疗效、膝关节功能Lysholm评分、生活质量SF-36评分和并发症发生情况。结果治疗前,两组患者骨生化指标、膝关节功能Lysholm评分、生活质量SF-36评分均无明显差异(P0.05)。治疗后,观察组切口长度、出血量、术后引流量、下床时间、NBAP明显少于对照组(P 0.01),观察组手术时间、Ca~(2+)、CT、BMP水平、Lysholm评分和SF-36评分均明显高于对照组(P 0.01)。观察组治疗有效率为90.38%,明显高于对照组80.77%(P 0.01)。观察组并发症发生率为11.54%,明显低于对照组28.84%(χ~2=4.69,P=0.002)。结论关节镜引导下复位内固定能够明显提升FTP患者的疗效,促进膝关节功能恢复,改善患者骨代谢指标,提高患者的生活质量,值得向临床推广应用。

Preventable iatrogenic cause of foot-drop in knee injuries with literature review

PurposeCommon peroneal nerve palsy is quite disabling and every effort should be made to prevent its injury during the treatment.MethodsWe retrospectively reviewed the prospectively collected data of 7 cases of tibial plateau fractures in association with proximal fibula fracture from January 2019 to September 2019 who presented to emergency room of our hospital.ResultsIn addition to fibular neck fracture, the first case had type 6 tibial plateau displaced fracture and the second case had displaced acetabular fracture with instability of knee with tibial tuberosity avulsion. common peroneal nerve palsy developed following application of distal tibial skeletal traction in both the cases. Other 6 such cases remained neurologically intact as traction was not applied to them.ConclusionSuch iatrogenic complication could have been prevented if the injury pattern of "concomitant medial and lateral columns" of the proximal leg is kept in mind by the treating surgeon before applying skeletal traction.
