Our Ender rods made of 00Cr20Ni75Mo5 alloy were tested for their mechanical strength. The tensile strength was 136kg/mm~2 and ductility coefficient 9%, similar to that of imported Ender rod material. The rods were also compared with goose-head nail and low angled intramedullary nail for breaking load in femoral intertrochanteric fracture models. When 2 or more Ender rods were used, the breaking force was greater than the other 2 nails. In addition, Ender rods are subjected to considerably less...

Our Ender rods made of 00Cr20Ni75Mo5 alloy were tested for their mechanical strength. The tensile strength was 136kg/mm~2 and ductility coefficient 9%, similar to that of imported Ender rod material. The rods were also compared with goose-head nail and low angled intramedullary nail for breaking load in femoral intertrochanteric fracture models. When 2 or more Ender rods were used, the breaking force was greater than the other 2 nails. In addition, Ender rods are subjected to considerably less stress because of shorter distance from compression vector. The local made Ender rods have been used in 21 patients with good union of the fracture.

Ender钉为一弹力金属髓内钉,用以固定股骨粗隆间骨折。作者对沪产弹力钉的钢材作了抗张和延伸性的测定,结果与进口钉相仿。又在体外股骨骨折标本中测试了弹力钉所能受的应力,并与鹅头钉和低角度髓内钉作比较,结果是两根以上的弹力钉能受的破坏负荷为最高。作者在临床上应用此钉共21例。1例死亡,余在术后2周开始行走,均愈合良好。

Twenty seven nonunion cases of femoral shaft fracture after open reduction and internal fixation were reported. Ofthem seventeen cases were fixed with plates and screws but only four cases met the general requirements for internal fixation. In nine cases fixed with intramedullary nail,the nails of five cases were too small to be fitted in the medullary canal. Other causes included fracture of the plates and the medullary nails,infection and so on. Twenty--six nonunion cases were cured through...

Twenty seven nonunion cases of femoral shaft fracture after open reduction and internal fixation were reported. Ofthem seventeen cases were fixed with plates and screws but only four cases met the general requirements for internal fixation. In nine cases fixed with intramedullary nail,the nails of five cases were too small to be fitted in the medullary canal. Other causes included fracture of the plates and the medullary nails,infection and so on. Twenty--six nonunion cases were cured through one opera- tion and one case was cured after reoperation. For most cases,the union of fracture was accomplished by decollement of bone cortex pedicle and firm internal fixation without bone graft. Factors pertaining nonunion of fracture were mainly neglecting the principles of internal fixation and improper operation.

报告股骨干骨折切开复位内固定术后不愈合27例。其中,17例钢板固定者,只4例符合要求;9例髓内针固定者,有5例针短小。尚伴有固定方法,钢板或髓内针断裂,以及感染等方面原因者。本组再手术26例1次手术治愈,1例2次手术治愈。绝大部分经带蒂骨皮质剥离和坚强内固定术后而愈合,不需植骨。产生骨折不愈合的诸因素中,以忽视内固定的基本原则与术中操作不当为主。
