【摘要】 目的 探讨一种新的内固定材料在关节内骨折中的应用价值及适应证。方法 用自身增强聚乙交酯(SR-PGA),聚丙交酯(SP-PLLA)和国产聚-DL-乳酸(SR-PDLLA)可吸收螺钉治疗踝关节,膝关节,髋关节,肱骨上端骨折等关节内骨折共62例,均采用常规关节手术入路,根据骨折块大小不同,用1～4枚螺钉固定,术后用石膏固定4～8周。结果 关节解剖复位38例,占61.3％;近解剖复位18例,占29％;复位欠佳6例,占9.7％。关节功能优20例,占32.3％,良32例,占51.6％,可6例,占9.7％,差4例,占6.5％,优良率达83.9％。全组病例随访3～10个月,4例术后出现骨折端不同程度的移位,占6.5％。结论 关节内骨折采用可吸收内固定螺钉固定可避免二次手术,减少关节内粘连,是一种理想的关节内骨折固定物,但应严格掌握其适应证,在行该类手术时,须同时作好行金属内固定的准备。更多还原

【Abstract】 Objective To explore the clinical application value and indication of a new material in intra-articular fracture Methods There were 62 cases,male 46,female 16 in this group. All fractures were fixed with 4.5 mm self-reinforced absorbent screws, according to the common articular incision, use 1-4 absorbent screws to fix the fracture slice and use plaster bandage to fix the extremity after operation for 4-8 weeks,and then exercise the function of extremities. Results There were 38 cases of anatomical restoration,the percentage was 61.3% approximately anatomical restoration 18 cases, the percentage was 29% ;bad restoration 6 cases, the percentage was 9.7% . The excellent and good percentage was 83.9%. The follow-up period ranged from three months to ten months, six months in average of all patients, there was replacement of fracture in four cases,the percentage was 6.5% .Conclusion The absorbent screws have definite effect on intra-articular fracture and good biocompatibility. It can avoid the second operation and reduce the adhesion,so it is a ideal internal fixational material.更多还原
