Description
Technical field
It is specially a kind of for the device of knee sprung angle to be auxiliarily fixed the present invention relates to medical field.
Background technique
When carrying out knee joint inspection, it is recessed that habitual dislocation of patella refers to that kneecap deviates from femoral bone pulley in active procedure, often
Occur in teenager.Although kneecap habitual dislocation is not very common in injury gained in sports, due to can after dislocation of the patella
With self-resetting, therefore easily mistaken diagnosis or failed to pinpoint a disease in diagnosis in clinical diagnosis.Dislocation of the patella is mostly outside lateral dislocation, dislocation
Afterwards, during self-resetting, medial patellar and condyle of femur lateral surface are hit the rock-steady structure on the inside of patellofemoral joint, can be caused
Cartilage damage or tangent line fracture.The patient feels can have dislocation feeling or powerless to the unexpected severe pain of knee joint.After knee joint stretches
The frequent self-resetting of kneecap resets often audible " card clatter " sound.Then knee joint swells and ache.These symptoms can be with meniscus tear
Obscure.Conventional knee joint anterioposterior and lateral film is very necessary, and whether 30 degree of lateral projections of bending the knee are observed with the presence of patella alta；Shooting
30 degree of bending knee or 45 degree of Patellar axial radiographs (Merchant) or CT film, it can be found that subluxation on the outside of kneecap.Optimal inspection
Checking method is magnetic resonance, can clearly indicate patellofemoral joint subluxation, effusion of knee joint, while can also determine whether adjoint
Condyle of femur cartilage damage or other intra-articular structural damages.These check that certain angle that requires to bend the knee is checked, angle
It is incorrect to be easy to cause observation and measurement data inaccuracy, while needing the device of a stabilized knee, some reviews time
It is long, avoid the motion artifact in checking process.
Existing knee joint stabilising arrangement is usually that autonomous disposing way can not accurately fix knee joint angle, and
The knee joint of patient often moves after putting, and motion artifact and angular deviation when scanning is caused, if utilizing some pads
Son is unable to satisfy angle requirement again, leads to the inaccurate of measurement data, while the height of patient is different, existing knee joint is stablized
Device cannot be suitble to each patient.
