Description
Technical field
The invention mainly relates to nut bone operation set nail location technology more particularly to a kind of nut bone operation set screw positioning device and
Localization method.
Background technology
Fracture of scaphoid bone accounts for the 71.2% of fracture of carpal bone, is the common disease of orthopaedics.The treatment of fresh fracture of scaphoid includes operation
And non-operative treatment.Non-operative treatment is mainly long-armed or galianconism plaster cast is fixed, and is primarily adapted for use in stable fracture.But it is outer
The fixation for treatment time is long, complication is more.Since long-time gypsum is fixed, bone nonunion, osteonecrosis, fracture loose, muscular atrophy and
The complications such as anchylosis are very high.So clinically the fracture of no displacement advocate operative treatment more.Percutaneous spiral shell
It follows closely in minimally invasive and is fixed on the therapeutic modality that home and abroad has been increasingly becoming a relatively common acute fracture of scaphoid.Absolute hand
Art idicatio includes nut bone proximal pole fracture or the fracture of nut bone nearside 1/3 and without displacement or slight displacement but can closed reduction person.Phase
Include fresh fracture of scaphoid of the stable type without displacement to idicatio, gypsum braking cannot be received and have stronger progress early ambulant or
The patient of sports demand.Recently Study of evidence based medicine is the results show that the method using Percutaneous fixation can shorten stabilization
It is asked when the healing of fresh fracture of scaphoid, reduces the incidence of disunion.
The length of the placed angle of internal fixation screw, position and screw is to determine fracture of scaphoid screw internal fixation operation
Good and bad key factor.Studies have shown that if screw fail preferably to be placed in nut bone central long axis or screw length it is too short or
It is long, articular cartilage abrasion, the severe complications such as unstable or disunion of fracturing can be caused.However, in fracture of scaphoid through intradermal
In fixed operation, accurate this committed step not a duck soup of merging hollow screw, main cause is that nut bone is located at nearly row's carpal bone oar
Side, form is elongated, shape such as boat, and three-dimensional configuration is complicated irregular, be visually described as " shelled peanut of distortion ", furthermore, boat
The position of bone is set hidden, and nut bone waist and proximal pole are narrow, and the space of internal fixation screw merging is small, and serious forgiveness is low.Compatriots' nut bone is more American-European
Personage's smaller, the requirement higher of operation, Minimally Invasive Surgery operation difficulty bigger make clinical application be restricted.Bushnell's etc.
Even if studies have shown that the nut bone waist of no displacement fracture the incidence that complication is fixed into percutaneous if up to 29%.Separately
Outside, it when having an X-rayed again after adjustment guide pin in surgical procedure, due to the variation of wrist and forearm position, often needs repeatedly to have an X-rayed
The perspective contrast image under same position can be obtained.On the one hand it threads a needle repeatedly, it is heavier to the damage and failure of patient part, it is easy broken
The blood of bad nut bone is transported, and effective healing of fracture is influenced；On the other hand, such operation needs to carry out x lines perspective repeatedly, and inspection is led
The position of needle and screw, extends operating time, increases operating theatre staff and patient has need to receive radiation insult repeatedly
Risk.It has been reported that even if fluoroscopy during operation number is effectively reduced by complementary outer fixation in art, when shortening operation
Between, but its result shows and still needs to average adjustment Kirschner wire l~3 time, perspective number 9~12 times.
Foreign countries begin with leading mechanism and carry out fracture of scaphoid through intradermal solid using Computer navigation surgery auxiliary at present
Fixed operation.Computer Technology of surgery navigation can instruct operative doctor to be accurately positioned and be oriented in art, and it is sudden and violent also to reduce radioactive ray
Dew, can theoretically solve the above problems.But the computer navigation surgery systems of current home and abroad are mainly used in larger bone and close
Section field, and nut bone is small, complicated, operation required precision is high, and it is special that the design and application of operation guiding system have
Requirement.At present to the research of the operation guiding system suitable for this kind of smaller bone of nut bone, home and abroad is still in the base of starting
Plinth conceptual phase.Furthermore it is expensive due to researching and developing such system cost, even if researching and developing successfully, it is also difficult to be pushed away extensively in basic hospital
Extensively, it is unfavorable for diagnosis and treatment of the basic hospital to such patient.
