  • Research on the Range of Motion Measurement System for Spine Based on LabVIEW Image Processing Technology

    A measurement system based on the image processing technology and developed by LabVIEW was designed to quickly obtain the range of motion (ROM) of spine. NI-Vision module was used to pre-process the original images and calculate the angles of marked needles in order to get ROM data. Six human cadaveric thoracic spine segments T7-T10 were selected to carry out 6 kinds of loads, including left/right lateral bending, flexion, extension, cis/counterclockwise torsion. The system was used to measure the ROM of segment T8-T9 under the loads from 1 N·m to 5 N·m. The experimental results showed that the system is able to measure the ROM of the spine accurately and quickly, which provides a simple and reliable tool for spine biomechanics investigators.

  • 股前外侧皮瓣重建咽喉食管一例近期疗效

    目的 总结1 例股前外侧皮瓣重建颈段食管的方法及效果。 方法 2007 年9 月,收治1 例42 岁下咽癌男性患者(T4N3M0)。病程4 个月。患者声音嘶哑,吞咽困难。2003 年曾行食管癌(中下段)根治术,胃代食管,食管胃颈部吻合术。行肿瘤切除术后采用大小为10 cm × 7 cm 的股前外侧皮瓣重建咽喉食管。 结果 术后股前外侧皮瓣成活,无血肿及感染等并发症发生。供区Ⅰ期愈合。患者术后2 周进食通畅,无咽漏。术后1 个月,吞钡X 线检查,再造食管无狭窄和食管吻合口漏发生。患者获随访6 个月,进食良好,皮瓣无坏死,肿瘤无复发。 结论 股前外侧皮瓣重建咽喉食管是一种安全、有效的手术方法,并发症少。

  • 自体肋软骨移植治疗单侧唇裂修复术后鼻畸形

    目的 应用自体肋软骨植入对先天性单侧唇裂修复术后鼻畸形进行修复重建,以获得较完美的鼻部形态。 方法 2006 年7 月- 2007 年12 月,收治25 例先天性唇裂修复术后单侧鼻畸形患者。男18 例,女7 例;年龄12 ~ 23 岁,平均18.4 岁。鼻小柱过短及偏向健侧、鼻尖扁平、鼻孔不对称及鼻翼塌陷。术中根据鼻畸形取自体肋软骨雕刻成形后,植入患侧鼻部或鼻翼外侧脚基底部,固定后将患侧鼻翼软骨和软组织复位至正常解剖位置。 结果 患者术后切口愈合良好,供软骨区无并发症发生。鼻外形满意,鼻尖高度及形态、双鼻孔大小基本对称,鼻小柱延长,鼻尖扁平及鼻翼塌陷恢复满意,鼻唇角接近正常。25 例均获随访,随访时间2 个月~ 1 年,患者无移植软骨排出,外形良好。 结论 应用自体肋软骨移植治疗唇裂修复术后鼻畸形是一种较理想的治疗方式。

  • Analysis of influencing factors of muscular calf vein thrombosis after hip and knee arthroplasty

    Objective To explore the influencing factors of muscle calf vein thrombosis (MCVT) after hip and knee arthroplasty. Methods Convenience sampling method was used to select patients who underwent hip or knee arthroplasty in 4 hospitals in Beijing, Jiangsu and Hainan between March 2021 and May 2022 as the research subjects. They were divided into MCVT group and non-MCVT group according to whether the lower limb MCVT occurred on the 3rd postoperative day. Generalized linear mixed model was used to analyze the influencing factors of MCVT. Results A total of 278 patients were included, including 47 patients in the MCVT group, accounting for 16.91%, and 231 patients in the non-MCVT group, accounting for 83.09%. Generalized linear mixed model analysis showed that the ambulation on the first postoperative day [odds ratio=0.364, 95% confidence interval (0.159, 0.832), P=0.017] and preoperative activated partial thromboplastin time [odds ratio=0.884, 95% confidence interval (0.785, 0.994), P=0.040] were protective factors for MCVT after hip and knee arthroplasty. Conclusions The ambulation on the first postoperative day and preoperative activated partial thromboplastin time are protective factors for MCVT after hip and knee arthroplasty. The relationship between hypertension, drainage and MCVT needs to be further explored. Clinical medical staff should pay close attention to the postoperative ambulation of patients undergoing hip and knee arthroplasty, encourage and guide patients to get out of bed early, comprehensively assess the patients’ condition and the risk of postoperative MCVT, and flexibly formulate individualized prevention and treatment plans to avoid the occurrence of MCVT and improve the prognosis.

  • Research progress on the hemodynamic mechanism and application of ankle pump exercise in preventing deep vein thrombosis

    Ankle pump exercise (APE) is one of the basic measures to prevent the formation of deep vein thrombosis, which has been widely recognized for its advantages of simplicity, safety, and ease of perform. However, there is still controversy regarding the frequency, duration, angle, position, and adjunctive exercise of APE. This article will review the hemodynamic and hemorheological effects of APE for the prevention of DVT, the current status of clinical application, and new advances in adjunctive APE, in order to provide methods and guidance for clinical staff.
