Description
Technical field
The present invention relates to mankind life article more particularly to medical instrument, especially a kind of general atlas dentata of cervical vertebra is planted
Bone block bridging board.
Background technique
Sick and wounded, lopsided, tumour and inflammation etc. can destroy the ligament or bony structure of the atlas and axis of human body, lead to extensive region pivot
Vertebra is unstable or dislocates, and narrow especially for cantle caused by atlas developmental deformity, spinal canal stenosis, compression of spinal cord needs
Cantle is cut off to reach abundant decompression.Main treatment method be atlas and axis Posterior Bone Graft fusion, but atlas volume itself compared with
Small, cantle is unique common implant bed.Currently used alternative be do Occipitocervical fussion, although however it is such operation reach
The purpose of fusion, thoroughly lose occipito-atlantoid articulations mobility (although only 10-15 ° bend and stretch it is living with 8 ° of lateroflexion
It is dynamic but for the sufferer for having lost rotation function or critically important), and Occipitocervical fussion operation wound is big, leads
The decline of patient's Postoperative Satisfaction is caused, quality of life is not high.
As it can be seen that the fusion of atlas and axis Posterior Bone Graft depends on the integrality of cantle, the pillow neck that wound otherwise can only be selected bigger
Fusion.Even for the complete sufferer of cantle, lacks unified fixation material since plant bone mass is fixed, cause plant bone mass locally steady
Qualitative deficiency, bone grafting failure incidence are higher.The nail stick card pressure used in the fusion of atlas and axis Posterior Bone Graft, wire binding, individually
The methods of screw fixation, stability is poor, frequently results in plant bone mass absorption, causes operative failure.Therefore, existing fixation side
Method cannot fundamentally realize that the physiological of cervical posterior column is rebuild.
Summary of the invention
The purpose of the present invention is to provide a kind of general atlas dentata plant bone mass bridging board of cervical vertebra, the bridging board is integrated
T-shaped structure design, while plant bone mass is fixed on atlas and axis rear, it creates conditions for the bone bridge joint of Posterior Bone Graft block, it is maximum
The stability for increasing rear pillar of limit.In particular, can will be tied after atlas part cantle is cut off in art using the bone plate
Structure bone grafting is firmly fixed to fastly between the arch of posterior atlas and lamina of axis of remaining, to significantly improve fusion rate of bone graft and extensive region
Structural stability after dentata.
