Objective To analyze the intermediate-term results associated with the use of Zweymüller hip system. Methods Review the 116 cases (142 hips) who were treated with total hip replacement from 1996 to 2002 by a single surgeon using cementless Zweymüller hip systems. Results Sixty-one cases (77 hips) were followed up, 50 cases (64 hips) were evaluated both clinically and radiographically while 5 cases (6 hips) and 6 cases (7 hips) were only evaluated clinically and radiographically respectively. The average follow-up period was 7.3 years(range 5 to 11 years). The mean preoperative Harris Hip Score was 46 while the mean postoperative Harris Hip Score was 93. Distal cortical hypertrophy and medullary sclerosis were observed in 30 hips(42.3%) and 33 hips(46.5%) respectively. Heterotopic ossification arose in 45 hips (63.4%). Radiolucent lines occured in 27 stems(38.0%) but in no cups. Radiolucent lines were mosdy observed in Gruen zones 1. Osteolysis occured in 7 cups (9.9%) and 18 stems (25.4%). Osteolysis was mostly observed in Delee Zone 3 and Green zone 7. In the distal Gruen zones 3, 4 and 5, no radiolucent line or osteolysis was observed. No hips had been revised, 3 cups needed revision surgery because of aseptic loosening. Conclusion The 5-11 years follow-up results are satisfactory, but osteolysis is common 相似文献

目的:观察不带血管蒂的自体腓骨移植在肩腕关节重建中的应用和长期疗效。方法:于1985-12/2003-12对南方医院23例肱骨近端,19例桡骨远端骨肿瘤患者分别进行囊内刮除或瘤段切除,采用不带血管蒂的自体近端腓骨移植重建肩、腕关节,术中采用自体腓骨支撑内固定或4孔钢板螺钉内固定。术后定期随访,X射线片复查,观测患者肩及腕关节活动度。采用国际骨骼肌肉肿瘤协会评分系统进行术后功能评价,满分为30分。结果:①42例术后经平均6年8个月的随访,仅3例患者出现肿瘤原位复发。②术后6个月进行随访功能评价,国际骨骼肌肉肿瘤协会评分系统评分保留关节面的肱骨近段肿瘤切除重建术后为23~30分(均28平分)骨近段移植重建肩关节术后为13~21分(平均16分);腕关节重;腓建为16~28分(平均23分)。结论:①不带血管的腓骨移植在肩、腕关节重建及近关节骨缺损重建中,是一个较理想的选择方案。②对于肱骨近端良性肿瘤,应尽量采用保留肩关节面,自体腓骨支撑重建的方法。③对于桡骨远端的肿瘤,腓骨近段重建腕关节可取得较好的外观和功能,可全部采用瘤段切除,腕关节重建手术。 相似文献

目的:探讨不对称性臀肌挛缩所致骨盆倾斜及双下肢不等长的病机、病理、临床表现及干预。方法:对1992—06/1999—06南方医科大学附属南方医院收治的135例不对称性臀肌挛缩所致骨盆倾斜及双下肢不等长患者进行体检及手术治疗。结果:患者年龄6~24岁,查体除有臀肌挛缩本身的体征外,尚有双下肢不等长、骨盆倾斜及脊柱腰段代偿性侧凸畸形,双侧下肢长度差距为0.5~6.2cm,平均1.7cm。而实际测量双侧大转子到内踝或髂前上棘到内踝的长度双侧相等。所有患者均行臀肌挛缩松解术,至术后2~4周,患者的外观畸形均基本消失,随访1年6个月~8年(平均4年8个月)畸形无复发。结论:不对称性臀肌挛缩的挛缩带牵拉可造成骨盆倾斜、脊柱侧凸及双下肢不等长,挛缩不对称程度越高,畸形越严重。手术完全松解挛缩组织可解除畸形。臀肌挛缩所产生的畸形均为代偿性,治疗时不可矫正各畸形而忽略了臀肌挛缩的治疗。 相似文献

目的:总结ⅡB及Ⅲ期骨肉瘤的保肢综合治疗的经验与体会,探讨保肢手术在晚期骨肉瘤治疗中的价值。方法:骨肉瘤患者行保肢手术43例,其中ⅡB期36例,ⅢA期1例,ⅢB期6例。肿瘤部位均位于四肢长骨干骺端。根据患者肿瘤局部的条件及全身情况,分别采用瘤段切除人工假体替代、瘤段骨体外灭活回植及自体骨移植术等保肢手段重建骨关节功能,同时根据患者具体情况给予手术前后化疗。7例Ⅲ期骨肉瘤患者中3例进行了肺部转移灶切除术。上肢瘤段切除后功能重建的所有患者及下肢行假体置换的病例术后近期即可进行康复训练。结果:患者1,2年的生存率分别为60%和35%,肿瘤局部复发率为14%。并发症主要为肩关节脱位、膝关节活动范围不理想、局部肿瘤复发。结论:对ⅡB及Ⅲ期骨肉瘤患者进行选择性的保肢手术是可行的,有效的术前化疗可以提高保肢手术成功的机会;经济问题是骨肉瘤患者治疗中的一个重要问题;人工假体可使保肢患者的生活质量明显提高。 相似文献

指骨内原发性腱鞘巨细胞瘤四例报告 总被引:3,自引:1,他引:2
指骨原发性骨内腱鞘巨细胞瘤较罕见,本院曾收治4例,作一报道。其临床特征是患指指骨增粗,有隐痛感.X线片显示指骨皮质骨膨胀性变而,极似指骨内生软骨瘤。组织学特征是组织细胞性基质细胞增殖,胞浆里网状空泡样改变,并有散在的多核巨细胞存在。诊断时需与骨巨细胞瘤相鉴别.4例均行病灶刮除加酒精灭活植骨治疗,术后随访平均13个月.功能恢复良好.未见复发.指骨内原发性腱鞘巨细胞瘤主要诊断依据必须结合病理改变及X线片表现,才能和其他有关肿瘤相鉴别. 相似文献

规范化与长期应用抗生素预防术后伤口感染的效果对比 总被引:138,自引:25,他引:113
目的 探讨不同方法预防性应用抗生素在骨科手术中的预防感染效果。方法 回顾性分析1997—2000年不同骨科择期手术患者,按抗生素预防性应用的方法分为两组:A组为规范性应用抗生素组,原则为一般情况下不应用抗生素,但手术中放入较多内植物等大手术时,则于麻醉后手术前应用1次,术后应用不超过36h,共计921人;B组为长期大剂量应用抗生素组,除按A组的方法应用外,术前1d可能应用抗生素,术后应用36h以上或直至患者体温降至37.5℃以下,共计1213人;对比两组患者的伤口感染率。结果 两组患者伤口感染分别为5例和8例,两组间感染率差异无统计学意义。结论 围手术期长期大剂量应用抗生素并不能进一步降低术后伤口感染率。 相似文献

共育体系中成骨细胞和破骨细胞生物学特性观察 总被引:13,自引:0,他引:13
目的建立成骨细胞和破骨细胞的体外共育体系,观察在此体系中成骨细胞和破骨细胞生物学特性的变化,探讨成骨细胞和破骨细胞间的相互作用。方法取髂骨松质骨,Ⅱ型胶原酶消化,分次获得成骨细胞和破骨细胞。建立培养上清相通但二者互不接触的成骨细胞-破骨细胞共育模型。以细胞增殖(MTT法)、碱性磷酸酶(ALP)活性代表成骨细胞的成骨活性,以抗酒石酸酸性磷酸酶(TRAP)活性、骨吸收陷窝面积代表破骨细胞的破骨能力,检测共育对成骨细胞和破骨细胞生物学特性的影响。结果成骨细胞呈饱满的梭形,ALP染色阳性;破骨细胞呈多核,TRAP染色阳性,可以吸收骨质形成骨陷窝。当成骨细胞与破骨细胞共育后,其MTT法OD值(0.60±0.08)较单独培养时(0.36±0.03)明显提高(P=0.000);其ALP活性(23.37±2.48)u/mg较单独培养时(18.33±0.34)u/mg明显提高(P=0.000)。破骨细胞与成骨细胞共育后,形成骨吸收陷窝的平均面积犤(6.55±0.34)×10-2犦μm2较单独培养时犤(5.15±0.17)×10-2犦μm2明显增大(P=0.000)。结论共育体系中成骨细胞和破骨细胞的功能相互促进,为骨组织代谢的体外研究提供了可靠的模型。 相似文献
