Abstract
Aim: Distal extra articular fractures of femur and tibia are difþcult to treat by conventional nails because of inability to use distal locking screws. The aim of this study is to analyse the effectiveness of this new I.M. Nail that does not require the use of distal locking screws for rotational stability. Methods & Material: Since 1994 we have treated a total of 68 such cases. Of these 40 were fractures of distal tibia and 28 were that of femur. Age range was from 11– 92. After insertion of the nail in the usual way, a ÒTrio WireÒ was introduced through the nail. This wire fans out in the distal segment which maintains rotational stability. Patients were mobilised with partial weight bearing within 3 weeks. Results: Most of the fractures were united without any signiþcant problem. Delayed union occurred in 2 cases. Breakage of the trio wire occurred in one case and 1 patient with supra-condylar fracture of femur needed revision for persistent varus deformity. Conclusion: We conclude that this I.M. Nail can be used effectively for þxation of these difþcult fractures. This is does not require X-ray exposure for distal locking. Operative time is thus minimised. This also saves surgeonñs hands from direct exposure to radiation. The þxation also allows for dynamisation of the fracture to promote early union.
