Description
Technical field
The present invention relates to medical instruments fields, and in particular, to a kind of ankle-joint artificial ligament.
Background technology
Ankle from sprains (Ankle sprains) would generally involve lateral ligament of ankle joint complex (the lateral
Ligament complex), this is a kind of very common injury gained in sports.Ankle from sprains more afterwards be also it is very good, greatly
Most of patients can be fully returned to that the ankle joint function before spraining is horizontal, but about have more than 25% strain patient because of processing
It is not good at slowly developing into chronic ankle-joint shakiness.Research shows that astragalus can be sent out when anterior talofibular ligament and calcaneofibular ligament are broken
Raw displacement, and then it is bad ankle-joint contraposition occur, and walk for a long time in ankle-joint subluxation state, articular cartilage is easy to wear
And destroy, lead to ankle joint wound arthritis, reduce the life quality of patient.The chronic instability of ankle-joint and the cartilage of astragalus
Damage is related, and astragalus cartilage damage is an early prediction index of ankle osteoarthritis.Hand is considered as when expectant treatment is invalid
Art is treated.It can increase the risk of complication in view of non-anatomical form reconstruction and bring changing for ankle and metapedes biomethanics
Become, so mainstream processing at present is more recommended to carry out anatomical form reconstruction.
The ligament of ankle-joint both sides helps to maintain the connection between bone, and Lateral collateral ligament of ankle joint is by three ligament groups
Into, i.e., anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL) and posterior talofibular ligament (PTFL), this three ligaments are risen from external malleolus,
Respectively forwardly, astragalus and root bone are terminated in downwards, backward, and lateral collateral ligament is the most weak ligament of ankle-joint.It is secondary on the inside of ankle-joint
Ligament is ligament most tough and tensile in ankle-joint, is risen from internal malleolus point, downward fan out is placed in navicular bone, astragalus, calcaneum, main
It wants to prevent ankle-joint from turning up during function.Ankle Ligaments Injury is one of most commonly seen soft tissue injury, with outside pair
Ligament injury is the most common, if dealing with improperly can cause ankle-joint unstable, can sprain repeatedly, repeatedly pain, the later stage is due to closing
, there is osteoarthritis in the unevenness of nodal section stress, seriously affects walking function.Lateral collateral ligament is damaged：II degree of ligament injury
Expectant treatment is invalid, considers that II stage operation rebuilds lateral collateral ligament.For III degree of ligament injury, to restore the stabilization of ankle-joint,
It should actively perform the operation and repair lateral collateral ligament.What medial collateral ligament was broken completely, should perform the operation reparation.
A kind of reconstruction operations of LARS artificial ligaments for ligament of ankle joint exist in the prior art：One is used first
Anterior talofibular ligament is fixed on the stop position that is connected of its distal end with astragalus, from here, ligament by the suture anchor of 4.75-mm
Move towards fibula channel in capsular ligament.Calcaneofibular ligament is fixed on the outside of its calcaneum at stop using same holdfast, ligament from this
In move towards to be deep to peroneal tendon and capsular ligament outside capsular ligament, also move towards fibula channel.From fibula anterior talofibular ligament and calcaneofibular ligament
Overlapping place starts to bore the channel of a diameter 5mm to fibula, pays attention to the traveling of fibula channel to be moved towards afterwards upwards by lower section fibula axis
Cortex on rear side of fibula, depth 25mm penetrate the cortexs of bone of both sides.LARS ligaments (are formed cyclic annular) above fibula channel and are worn
It crosses, has been both needed to stress tension, be then fixed with third root 4.75mm holdfasts.It is cut away from fibula rear side surface extra tough
Band.Using absorbable suture reconstruction lateral ligament complex, restore its imbricated texture, finally layering is closed operation and cut
Mouthful.Fig. 1 is the final fixed position of LARS artificial ligaments.
In a practical situation, Lateral collateral ligament of ankle joint is likely to occur three and is required to repair, it is also possible to occur there was only it
In one or two ligaments needs situation about repairing, different ligament different crowds repair the width of ligaments there is also difference, and
The ligament that these may need to be carried out at the same time reconstruction in the ankle also diseased forward and backward ligament of such as shin, LARS artificial ligaments pair
There is very big deficiency in the applicability of these situations.
