    • 摘要: 概述了钛及钛合金在医学领域的发展现状,以及常用的钛及钛合金表面处理技术,重点介绍了医用钛及钛合金表面耐蚀耐磨涂层、生物活性涂层和表面抗菌涂层的研究现状和发展趋势。在钛及钛合金表面制备涂层能够使其更适合作为植入物在医学领域应用,但由于涂层自身还存在一定局限性,临床试验也需要大量的时间,目前涂层还没有大规模应用到临床医疗中。为了尽可能地改善单一涂层存在的缺陷,多组元、多层复合涂层是目前医用钛及钛合金表面涂层的研究重点。

    • 摘要: 医学植入物的应用随着医学的发展而发展,植入物相关感染的发生也在院内获得性感染中占据重要地位.细菌黏附在植入物表面形成生物膜,生物膜下的细菌即为生物膜细菌.生物膜细菌有着独特的生物学特性,具有极强的抗生素抵抗性,是医学植入物感染最重要的致病机制.预防生物膜的形成、加速生物膜的降解、杀灭生物膜细菌是预防和治疗植入物感染的研究重点.

    • 摘要: 背景:以自体腘绳肌腱重建内侧髌股韧带是现在较流行的修复方式。目的:观察重建内侧髌股韧带治疗复发性髌骨脱位的中期临床疗效。 方法:回顾性研究2006年9月至2009年9月因复发性髌骨脱位而接受内侧髌股韧带重建的患者24例(25膝)资料,随访时间2-5年,平均3.1年,观察临床疗效、膝关节功能恢复及CT评估髌骨位置。 结果与结论:随访结果显示,IKDC 评分优良率为92%,2例(8%)患者再次发生髌骨脱位,需要再次手术治疗,随访时IKDC评分、Tenger评分、Lycholm评分明显高于术前(P<0.01)。结果证实,自体腘绳肌腱重建内侧髌股韧带治疗髌骨脱位中期临床疗效较好。

    • 摘要: BACKGROUND:Autologous hamstring tendon reconstruction of the medial patel ofemoral ligament is now more popular surgical procedure. OBJECTIVE:To study the clinical mid-term outcomes of isolated medial patel ofemoral ligament reconstruction for recurrent lateral patel ar dislocation. METHODS:The clinical data of 24 patients (25 knees) undergoing medial patel ofemoral ligament reconstruction for recurrent patel ar dislocation from September 2006 to September 2009 were retrospectively studied. Clinical, functional, and CT outcomes were assessed at an average of 3.1 years after surgery (range, 2-5 years), using recurrent instability as the primary end point. RESULTS AND CONCLUSION:The success rate of medial patel ofemoral ligament reconstruction for preventing recurrent dislocations was 92%. Two patients (8%) experienced a recurrent lateral patel ar dislocation, and required a reoperation. At final fol ow-up, the mean IKDC, Tenger and Lycholm scores were significantly higher than those before operation (P<0.01). Reconstruction of the medial patel ofemoral ligament for recurrent patel ar instability is a minimal y invasive operation and has a number of benefits. The mid-term clinical outcome was satisfactory.%背景:以自体腘绳肌腱重建内侧髌股韧带是现在较流行的修复方式。目的:观察重建内侧髌股韧带治疗复发性髌骨脱位的中期临床疗效。  方法:回顾性研究2006年9月至2009年9月因复发性髌骨脱位而接受内侧髌股韧带重建的患者24例(25膝)资料,随访时间2-5年,平均3.1年,观察临床疗效、膝关节功能恢复及CT评估髌骨位置。  结果与结论:随访结果显示,IKDC 评分优良率为92%,2例(8%)患者再次发生髌骨脱位,需要再次手术治疗,随访时IKDC评分、Tenger评分、Lycholm评分明显高于术前(P<0.01)。结果证实,自体腘绳肌腱重建内侧髌股韧带治疗髌骨脱位中期临床疗效较好。

    • 摘要: 背景:目前陶瓷制造工艺方面仍在不断改进,陶瓷对陶瓷摩擦界面的假体成为关节外科领域关注的焦点,并取得了良好的临床疗效,然而随着陶瓷对陶瓷摩擦界面假体的广泛应用,出现了假体碎裂和高调摩擦音等一系列问题。目的:探讨陶瓷对陶瓷全髋关节置换的初期临床疗效。方法:对常熟市第一人民医院2006年1月至2010年6月间小于55岁行陶瓷对陶瓷全髋关节置换的50例患者进行随访,其中男19例( 20髋),女31例(33髋),平均年龄45岁,随访时间平均20(12-42)个月。置换前后均采用Harris评分进行疗效评估,影像学随访包括髋臼假体外展角和前倾角,假体松动采用Kawamura及Engh标准,骨溶解采用Engh标准,异位骨化依据Brooker法评价。结果与结论:置换前Harris评分为(48.10±26.33)分,置换后为(91.10±19.78)分。置换后随访无患者有关节异响的主诉,未见假体松动,未发生假体周围感染,无可观察到的磨损和骨溶解,无明显异位骨化。其中,1例因髋臼陶瓷内衬碎裂翻修。可见陶瓷对陶瓷全髋关节置换对于年轻的骨质量较好的患者短期疗效显著,长期疗效有待于进一步随访。

However, with the wide application of ceramic-on-ceramic friction interface prosthesis, the prosthesis fragmentation and high-profile fricative appear. OBJECTIVE: To discuss the preliminarily clinical effects of ceramic-on-ceramic total hip arthroplasty. METHODS: Fifty patients less than 55 years old treated with ceramic-on-ceramic total hip arthroplasty between February 2006 and June 2010 in the First People’s Hospital of Changshu were enrol ed for fol ow-up visit. There were 19 male patients (20 hips) and 31 female patients (33 hips). The average age of the patients was 45 years. Al the patients were fol owed-up for an average of 20 months (ranged 12-42 months). The clinical effects were evaluated with Harris score preoperatively and postoperatively. Radiographic fol ow-up included the outreach angle and anteversion angle. The prosthesis loosening was evaluated with Kawamura and Engh standard. Osteslytic lesions were defined according to the Engh standard, and heterotopic ossification was defined according the system of Brooker. RESULTS AND CONCLUSION: The average Harris score improved from (48.10±26.33) points preoperatively to (91.10±19.78) points postoperatively. No patient presented joint abnormal sound, prosthesis loosening, periprosthetic infection, observed wear, osteolysis or heterotopic ossification. One patient had renovation due to acetabular ceramic liner fragmentation. It showed that ceramic-on-ceramic total hip arthroplasty offers a promising choice for young patients with better bone quality, and the long-term effect needs to be further observed.

    • 摘要: BACKGROUND:Autologous hamstring Rigidfix and Intrafix has been frequently used to fix and reconstruct anterior cruciate ligament. However, it lacks of evaluation of middle and long period of clinical outcomes. OBJECTIVE:To retrospectively evaluate the medium term clinical outcomes of anterior cruciate ligament reconstruction with hamstring tendon autograft by Rigidfix and Intrafix. METHODS:The 39 cases of anterior cruciate ligament injury were subjected to anterior cruciate ligament reconstruction with hamstring tendon autograft by Rigidfix and Intrafix under arthroscope. They were fol owed up for 2 years or more. The clinical outcomes were evaluated using Lyshlom score scale, IKDC2000 and Tegner score scale. RESULTS AND CONCLUSION:In the fol ow-up, IKDC2000 score and Lyshlom score were significantly increased fol owing Rigidfix and Intrafix fixation than before treatment (P<0.01). Results indicate satisfactory clinical outcomes of anterior cruciate ligament reconstruction with hamstring tendon autograft by Rigidfix and Intrafix. However, long-term fol ow up is needed to verify the feasibility of extensive application.%背景:以自体腘绳肌腱rigidfix、Intrafix固定重建前交叉韧带是现在较流行的手术方式,但缺乏中长期临床疗效的评价。目的:评估股骨端应用Rigidfix、胫骨端应用Intrafix固定自体腘绳肌腱重建前交叉韧带的中期临床疗效。方法:对39例前交叉韧带损伤患者在关节镜下行自体4股腘绳肌腱Rigidfix和Intrafix固定重建前交叉韧带,进行2年以上中期随访,并应用Lyshlom、IKDC、Tegner评分对治疗后临床疗效进行系统的评价。结果与结论:经过至少2年的随访发现应用Rigidfix和Intrafix内固定患者在IKDC、Lysholm评分明显高于治疗前(P<0.01)。证实在关节镜下应用自体4股腘绳肌腱Rigidfix和Intrafix重建前交叉韧带具有良好的中期临床疗效,但若大规模的使用,目前尚缺乏长期的临床随访结果。

    • 摘要: 背景:老年股骨颈骨折患者进行非骨水泥还是骨水泥人工股骨头置换是目前争论的焦点.目的:对85岁以上股骨颈骨折行骨水泥型人工股骨头置换患者的高风险的临床问题和功能结果进行评估.方法:32例股骨颈骨折患者进行骨水泥型双极人工股骨头置换治疗,所有患者在置换后1,3,6个月和以后每年行X射线片检查,患者平均随访2~5年.结果与结论:患者出现内科并发症发生5例(16%),在随访期间内死亡4例(25%).脱位发生1例(3%),患者均未出现异位骨化.平均Harris髋关节评分为84分.说明骨水泥型人工股骨头置换治疗老年股骨颈骨折效果较好,稳定安全.%BACKGROUND: A discussion is ongoing whether the elderly patients with femoral neck fractures should be treated with a non-cemented or a cemented hemiarthroplasty.OBJECTIVE: To evaluated the results of cemented hemiarthroplasty for femoral neck fractures in the patients older than 85 years with high-risk clinical problems and functional outcomes.METHODS: Thirty-two patients with femoral neck fractures were treated with cemented bipolar hemiarthroplasty. X-ray examination after operation was done at 1, 3 and 6 months and annually in all patients. The mean follow-up period was 2 to 5 years.RESULTS AND CONCLUSION: Medical complications occurred in five patients (16%) and four patients (25%) died within the follow-up period. Dislocation occurred in one patient (3%). None of the patients had heterotopic ossification. The mean Harris-hip score was 84. Cemented hemiarthroplasty can provide stability, security and good outcomes for the treatment of femoral neck fractures in elderly patients.
