Objective To report the results of large segment allografts in the treatment for bone tumor. Methods A retrospective analysis of 79 consecutive cases of large segment allograft implantations after resection of bone tumors from september 1991 to october 1998 was conducted. The allogeneic bone healing were observed. Fifty five of the 79 cases had an average age of 28.8 years (ranged 9- 70 years). There were 38 osteosarcomas, 12 aggressive giant cell tumor of bone, 29 other bone tumors. Inter segmental allograft...

Objective To report the results of large segment allografts in the treatment for bone tumor. Methods A retrospective analysis of 79 consecutive cases of large segment allograft implantations after resection of bone tumors from september 1991 to october 1998 was conducted. The allogeneic bone healing were observed. Fifty five of the 79 cases had an average age of 28.8 years (ranged 9- 70 years). There were 38 osteosarcomas, 12 aggressive giant cell tumor of bone, 29 other bone tumors. Inter segmental allograft was performed in 24 cases, osteoarticular allograft 50 cases, allograft and prosthesis 5 cases. The mean length of allograft was 13.5 cm (ranged 8- 22 cm). The types of fixation included common intramedullary nailing in 16 cases, interlocking intramedullary nailing in 53 cases, plate in 5 cases, prosthesis 5 cases. Results Followed up period ranged from 5 months to 7 years (average, 2.8 years) in 67 cases. 62 cases had union and 5 non unions. There was significant difference between the rate of union after fixation with common intramedullary and that after interlocking intramedullary fixation (P<0.05).The major complications were reccurrence in 8 cases, nonunion 5 cases had excellent results,23 cases good, 11 cases fair and 8 cases poor. Conclusion The allograft bones implantation is a most desirable graft material for repair of bone defected in course of limb salvage following resection of bone tumors. Satisfactory union were obtained with a stable interlocking intramedullary nail fixation.

Objective:To study effect of internal fixation on the healing of intercalary bone allografts.Methods:The bone intercalary defect animal models were made on New Zealand white rabbits at the middle shaft of the femur in which 1.5cm of diaphysis and periosteum were removed.36 rabbits were randomly divided into two groups.The bone defect was filled by the similar segment from another rabbit which were frozen in bone bank in each group.One group were fixed with 3mm circular-intramedullary nailing,the others were...

Objective:To study effect of internal fixation on the healing of intercalary bone allografts.Methods:The bone intercalary defect animal models were made on New Zealand white rabbits at the middle shaft of the femur in which 1.5cm of diaphysis and periosteum were removed.36 rabbits were randomly divided into two groups.The bone defect was filled by the similar segment from another rabbit which were frozen in bone bank in each group.One group were fixed with 3mm circular-intramedullary nailing,the others were fixed with 3mm triangular-intramedullary nailing.Observations were done with bone scintigraphy and hemaloxylin and eoxin stain histological examinations at the 1,2,3 months postoperative.A retrospective analysis of 69 consecutive clinical cases of large-segment allograft implantations performed from Sep.1991 to Oct.1998 was conducted.All patients had bone tumors.The allogeneic bone healing were observed.Sixty-nine at the time of treatment was 31.4 years (ranged 9~70 years).Sixteen were fixed with common intramedullary and fifty-three were fixed with interlocking intramedullary nails.Results:The frozen bone of allografts being able to produce bone conduction is similar in two groups.ECT showed that bone metabolism were more active in the first and second month postoperative in triangular-intramedullary nailing group( P <0.05) and it is similar in two group at the third month postoperative.Follow-up time ranged from 5 months to 6.5 years (averaged,2.6 years)in 57 cases.52 cases were union and 5 cases were non-union.There was significant difference between the rate of union after fixation with common intramedullary and that after interlocking intramedullary fixation( P <0.05).Conclusions:The satisfactory union are obtained of in with stable interlocking intramedullary nailing.

目的 :研究内固定对异体骨段移植愈合影响的实验与临床观察。方法 :采用新西兰大白兔股骨中段切除1.5cm骨干和骨膜实验动物模型。将 3 6只兔随机分成圆形髓内针内固定组和三棱形髓内针内固定组。于术后第 1、2、3个月行ECT检查、HE染色组织学观察异体骨愈合过程。比较普通非交锁髓内针和特制交锁针固定对异体骨修复骨肿瘤保肢术中瘤段切除大段骨缺损的治疗情况。结果 :圆形髓内针内固定组和三棱形髓内针内固定组异体骨移植愈合组织学过程相似 ,但三棱形髓内针内固定组在第 1、2个月时骨代谢活跃 (P <0 .0 5 )。 5 7例异体骨段移植随访 7个月~ 6.5年 ,平均 2 .6年 ,结果异体骨愈合 5 2例 ,不愈合 5例。其中普通非交锁髓内针 12例 ,骨不连 3例 (2 5 % ) ;特制交锁髓内针47例 ,骨不连 2例 (4 .3 % )。普通非交锁形髓内针易发生异体骨移植不愈合 (P <0 .0 5 )。结论 :稳固的髓内针固定有利于异体骨愈合。

Methods Sixty-eight patients with open tibial fractures were treated with emergency debridement and interlocked intramedullary fixation and randomized into two groups, ie, reaming group with 36 fractures (five type Ⅰ, eight type Ⅱ, seventeen ⅢA and six type ⅢB) were treated with nails...

Objective To determine the effect of interlocking intramedullary nail in treatment of open tibial fractures and compare clinical results of intramedullary nailing with that of reaming and without reaming. Methods Sixty-eight patients with open tibial fractures were treated with emergency debridement and interlocked intramedullary fixation and randomized into two groups, ie, reaming group with 36 fractures (five type Ⅰ, eight type Ⅱ, seventeen ⅢA and six type ⅢB) were treated with nails and non reaming group with 32 fractures (three type Ⅰ six type Ⅱ, sixteen type ⅢA, seven type ⅢB) treated without reaming nails. Main outcome measurements were average blood loss and operation time, early postoperative complications, fracture union, infection, failure of the implant and anterior knee pain. Results No clinically significant differences were found between two groups in regard to the technical aspects of the procedure or the rate of compartment syndrome. Operation time in reaming group was 8.8 minutes longer than that in non reaming group. There appeared postoperative compartment syndrome in three cases including one case in reaming group and two in non reaming group; the average union time was 29 weeks in reaming group and 30 weeks in non reaming group; bone non union was found in five cases (7%) including two cases (6%) in reaming group and three (9%) in non reaming group; malunion was seen in three cases (4%) including two cases (6%) in non reaming group and one (3%) in reaming group; five cases (7%) with infection included three cases (9%) in reaming group and two (6%) in non reaming group; anterior knee pain was found in 16 cases (44%) in reaming group and 12 (38%) in non reaming group.screw breakage was seen in 11 cases (17%) including two case (12%) in reaming group and nine (28%) in non reaming group with statistical difference (P<0.05); there was statistically significant difference between both groups(P<0.05). Conclusions Interlocking intramedullary nailing is a safe and effective technique for management of open tibial fracture. Reaming does not add the risk of complications such as compartment syndrome, deep infection, non-union, malunion and anterior knee pain in open tibial fracture.

目的探讨交锁髓内钉治疗开放性胫骨骨折的效果,并比较扩髓与非扩髓技术治疗开放性胫骨骨折的临床效果及并发症。方法对68例开放性胫骨骨折患者实施了急诊清创、交锁髓内钉内固定术。患者随机分为两组扩髓组36例(Gustilo分型Ⅰ型5例,Ⅱ型8例,ⅢA型17例,ⅢB型6例);非扩髓组32例(Gustilo分型Ⅰ型3例,Ⅱ型6例,ⅢA型16例,ⅢB型7例)。观察指标包括手术时间及出血量、术后早期并发症、骨折愈合情况、感染、内固定物失败、膝前痛等。结果扩髓组平均手术时间较非扩髓组长8.8min;术后3例出现骨筋膜间隔综合征,扩髓组1例,非扩髓组2例。平均骨折愈合时间扩髓组为29周,非扩髓组为30周。骨不愈合共5例(7%),扩髓组2例(6%),非扩髓组3例(9%);畸形愈合共3例(4%),非扩髓组2例(6%),扩髓组1例(3%);5例出现感染(7%),扩髓组3例(9%),非扩髓组2例(6%);膝前痛扩髓组16例(44%),非扩髓组12例(38%)。以上两组间差异均无统计学意义(P>0.05)。锁钉断裂11例(17%),扩髓组2例(12%),非扩髓组9例(28%),两组间差异有统计学意义(P<0.05)。结论交锁髓内钉可有效治...
