Abstract
An internal fixator of intramedullary nail joined with steel plate is disclosed. Said intramedullary nail has two screw holes at its near and far ends. A locking nail has spiral thread and is matched with said two screw holes of intramedullary nail for locking them together after it passes through femur, femur condyle and two steel plate. Its advantages include good mechanical stability, high effect on preventing shift between fractural bone segments, and promoting healing.
Description
One, technical field
The present invention relates to skeleton trauma fixture technical field, particularly the intramedullary pin associating steel plate inner fixing device of comminuted fracture treatment between distal femur and condyle.
Two, background technology
Complication rates such as at present, comminuted fracture is a kind of serious damage between Methods for Distal Femoral Fractures and condyle, handles comparatively difficulty, and its fracture site disunion, delayed union and knee joint function are limited are higher.Sum up according to clinical data report, Methods for Distal Femoral Fractures disunion incidence rate reaches 20%.In recent years, because the Application and Development of AO technology and novel internal fixation material descends distal femur disunion incidence rate to some extent.The retrograde interlocking intramedullary nail of AO technology is a kind of device for the treatment of Methods for Distal Femoral Fractures commonly used in recent years, and it is to drive in the wrong direction at femur for inserting interlocking intramedullary nail.Experiment and clinical effectiveness show that retrograde interlocking intramedullary nail has been obtained curative effect preferably, but then can not use for the case of comminuted fracture between femur, far-end merging condyle, because of it does not possess the device of comminuted fracture between the treatment condyle.
Three, summary of the invention
The present invention is exactly the internal fixator of interamedullary nail jined with steel plate of developing at comminuted fracture between femur, far-end merging condyle, be to treat simultaneously that distal femur merges, condyle bone meal fragility fracture be the inner fixing device of one, between the merging of treatment distal femur, condyle, obtain good medical effect during comminuted fracture.
Technical scheme of the present invention is to solve like this: internal fixator of interamedullary nail jined with steel plate, near-end and far-end at the interlocking intramedullary nail that drives in the wrong direction respectively are provided with two screwed holes, be threaded in the middle of the locking nail, locking nail passes the screwed hole locking of femur and intramedullary pin, locking nail passes the screw locking of condyle of femur and intramedullary pin, it is characterized in that: between the both sides of condyle of femur and the locking head of a nail, be fixed with that two are fallen "; " the shape condyle plate, condyle plate shape and condyle of femur form fit, locking nail passes that two are fallen "; " the locking of shape condyle plate and condyle of femur, two are fallen ", " shape condyle plate to leave the locking nail hole standby.
Characteristics of the present invention are: the near-end of the interlocking intramedullary nail that drives in the wrong direction passes the fixing hole of femur, fixed the fracture near-end, far-end by fall "; " the type condyle plate cooperates with intramedullary pin, condyle plate screws pressurization by pinning and intramedullary pin screw, make between condyle comminuted fracture obtain reduction and stable, comminuted intercondylar fracture is obtained medical treatment and recover.This device also has good mechanical stability, can effectively control the rear displacement and the rotation displacement of comminuted intercondylar fracture, helps the recovery of femur axis and keeps, and helps early stage joint motion, has accelerated the healing and the recovery of wound.And to the comprehensive classification C of AO tubular bone fracture
1, C
2, C
3The type fracture has better curative effect.
Four, description of drawings
Fig. 1 is internal fixator of interamedullary nail jined with steel plate (normotopia before the femur of a right side) front view.
Fig. 2 is internal fixator of interamedullary nail jined with steel plate (femur side position, a right side) side view.
Five, the specific embodiment
The internal fixator of interamedullary nail jined with steel plate specific embodiment (seeing Fig. 1,2) is being driven in the wrong direction The near-end of cross locking marrow nail 2 and far-end respectively are provided with two screwed holes, and locking nail 3 is middle with spiral shell Line, locking nail 3 pass the screwed hole locking of femur 1 and intramedullary nail 2, and locking nail 3 passes thigh Bone condyle 6 locks with the line screw of intramedullary nail 2, at both sides and the locking nail 3,5 of condyle of femur 6 Be fixed with two ", " shape condyle plates 4 between the cap, condyle plate 4 shapes and condyle of femur shape Coupling, locking nail 5 are passed two ", " shape condyle plates 4 and condyle of femur 6 lockings, two ", " shape condyle plate that falls leaves locking nail hole 7 (seeing Fig. 2) for subsequent use.
Claims (1)
1, internal fixator of interamedullary nail jined with steel plate, internal fixator of interamedullary nail jined with steel plate, near-end and far-end at the interlocking intramedullary nail that drives in the wrong direction respectively have two two screwed holes are arranged, be threaded in the middle of the locking nail, locking nail passes the screw locking of femur and intramedullary pin, locking nail passes the screw locking of condyle of femur and intramedullary pin, between the both sides of condyle of femur and the locking head of a nail, be fixed with that two are fallen "; " the shape condyle plate, condyle plate shape and condyle of femur form fit, locking nail are passed two ", " shape condyle plate and condyle of femur lockings, two are fallen ", " shape condyle plate to leave the locking nail hole standby.
