Multiple technologies combination.Mainly for high pressure, change weight bearing area in releasing bone to improve local blood supply.But above-mentioned treatment method is still deposited
In certain defect: simple marrow core drilling decompression lacks support, not can effectively prevent collapse of femoral head；Marrow core drilling decompression connection
Conjunction bone grafting operation will cause new damage and the operating difficulty of anastomosis of blood vessel is larger；Osteotomy clinical therapeutic efficacy is uncertain, concurrently
Disease incidence is higher.
The fundamental factor of caput femoris necrosis is the blood supply obstacle in femoral head, and it is micro- for treating the essential measure of ischemic disease
The improvement and reconstruction of microcirculation of circulation.Ilizarov is verified during in cortex osteotomy and gradually traction extends, bone and
The blood vessel hyperplasia of limbs is obvious, herein on basis, amplifies out lateral bone and moves, artificially manufacture bone wound small at one, benefit
With causing revascularization to realize revascularization with this feature of skeletonization after bone tissue wound.The bone of Ilizarov technology is moved micro-
For treating ischemic disease of lower extremity and infectious bone defect, post-surgical vascular radiography confirms rete vasculosum Reconstruction, is moved bone
Surrounding forms new vessels network abundant, has effectively rebuild the microcirculation of ischemic tissue.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, move skill by near end of thighbone transverse direction bone
Art, provide it is a kind of minimally invasive, it is easy to operate, for the pathogenesis of caput femoris necrosis, combine from many aspects, be that femoral head early stage is bad
A kind of completely new, minimally invasive, effective method is extremely provided, technical operation is relatively simple, while can reduce the burden of patient.
The technical solution of the utility model are as follows:
A kind of near end of thighbone transverse direction bone moves external fixing rack, it is characterised in that: including fixed frame body, the fixed frame master
Body is strip hollow structure, and the strip hollow structure is equipped with inner slide, slidably connects upper, middle and lower three on the inner slide
A sliding block, wherein upper and lower two sliding blocks are connected separately with guiding regulator, and thick kirschner is installed on the guiding regulator
Needle, the intermediate slider are connected with traction modulator, and the traction modulator is equipped with carrying threaded rod, the carrying threaded rod
On be cased with nut, the nut is fixed with thin Kirschner wire link block in traction modulator both ends, described one end for carrying threaded rod,
Thin Kirschner wire is installed on the thin Kirschner wire link block.
Further, the guiding regulator and sliding block are by rotation axis connection, and the traction modulator and sliding block are by rotating
Axis connection.
Utility model has the advantages that be it is a kind of minimally invasive, it is easy to operate, for the pathogenesis of caput femoris necrosis, from
Various aspects joint provides a kind of completely new, minimally invasive, effective method for femoral head early stage necrosis, and technical operation is relatively simple, simultaneously
The burden of patient can be reduced.
The utility model is described in further detail with reference to the accompanying drawings and examples.
