Description
Technical field
This utility model belongs to orthopaedic medical treatment fixture technology field, is specifically related to a kind of sustentaculum of talus screw Wicresoft and inserts guider.
Background technology
Calcaneus medial surface sub-dermal soft tissue is thick, the curved depression of surface of bone, and wherein 1/3 has a flat projection, for sustentaculum tali, its cortical bone is thick and hard, and sustentaculum tali has deltoid ligament, the attachments such as plantar calcaneonavicular ligament (spring ligament), have nervus vasculairs bundle to pass through inside calcaneus.
The process of the growth promoter of calcaneus is, calcaneus is ossified occurs in gestation the 23rd week, ossification center increases distortion after occurring gradually, and the 32nd week, the bone trabecula of arrangement disorder appearred in inside, 36th week, there is slight depression in the ossified middle part sole of the foot, the back side, in dumbbell shaped outward appearance, and term fetus, obviously, sole of the foot Middle face cortical bone thickens calcaneal sulcus depression.Calcaneus body bone trabecula increases slightly, increases, and has the general shape of adult's calcaneus.Calcaneus epiphysis is ossified to be occurred and epiphyseal line closes, anterior tubercle of calcaneus, sustentaculum tali and each bone articular surface from occurs completing to growth, men and women is all in certain hour scope. in calcaneus, 1/3rd is crest projection, is the corpora calcanei back side backward from summit; To front lower be facies articularis calcanea posterior, with associated section below body of talus.Articular cavity front lower rear in visible astragalus pleurapophysis excessive and corresponding with sustentaculum tali trailing edge, formation joint (having hardening facies articularis ossium) and talocalcaneal bridge.
Sustentaculum of talus bears the gravity in astragalus direction, is also attachment place of calcaneonavicular ligament, has very irreplaceable effect in human bearing and walking process, but also easy fracture in motion and walking process injuredly causes displacement fracture or pulverizing.
In prior art, fracture of calcaneus displacement or pulverize operative treatment scheme and be, fracture without displacement or not obvious time, use plaster fixing expectant treatment, fracture calcaneus displacement or when fracturing obvious, dial the scheme of art or internal fixation for treatment with sled:
1. osseous pin percutaneous reduction by leverage and fixing operation, gasbag hemostatic leukorrhagia carries out after being anesthetized.In calcaneus posterior tubercle heel string outside, stab an osculum with sharp knife, insert a thick osseous pin thus, in nearly folded block.Then by knee joint flexing, with lax gastrocnemius.Patient holds osseous pin and presses down to sufficient sole of the foot face, and sclerite is resetted.Finally osseous pin is driven into amphi position sclerite internal fixtion.2. open reduction compression screw internal fixtion, after external malleolus, lower 2 ~ 3cm begins to previous crops one curved incision, terminates in nut bone.After cutting deep fascia, peroneal tendon is led rearward, appear corpora calcanei transverse fracture and talocalcaneal joint.Direct-view is lower to the sub reduction of the fracture that will be shifted of periosteum stripping, is fixed to front upper use one piece of compression screw by the outside of rear sclerite.Ligule fracture or posterior tubercle fracture screw are fixed from top to bottom.3. open reduction and bone grafting otch and soft tissue appear the same, appear fracture of calcaneus and the articular surface thereof of astragalus inferior articular surface and Compressional depression.Calcaneus depressed fracture lower edge is inserted to, by the sclerite percutaneous reduction by leverage of compression with periosteum stripping.There is the bone block of cortical bone in three faces that residual clearance fills out to take from ilium.Postoperative plaster fixing was in functional position 6 ~ 8 weeks.4. arthrodesis introduces two kinds of methods herein, all occurs that traumatic arthritis is for indication with the later stage.5. osteotomy of calcaneus art is due to the horizontal shape compression fracture of calcaneus, does not give reset in early days,
angle and longitudinal arch of foot disappear, but subtalar joint traumatic arthritis is not obvious or comparatively the lighter, this operation feasible.With the micro-curved incision in outside, after cutting deep fascia, musculus peroneus is led forward upward.Subperiosteum is peeled off after on calcaneus, outside and sole of the foot face.Calcaneus is made wedge osteotomy, after taking out triangle bone block, is fixed towards upper by the sole of the foot with one piece of compression screw.
In fracture of calcaneus operative treatment, the normal screw position that occurs is unsatisfied with at present, the even generation of the Iatrogenic Complications such as inside structure damage, the medial surface of screw being inserted below and sustentaculum tali in sustentaculum of talus of mistake, the smooth of big toe Flexor hallucis longus tendon and vagina tendinum musculi flexorum digitorum pedis pipe will be affected, cause dysfunction and pain, and have injured blood vessel and neural possibility.Outside calcaneus operative approach onlyly in current fracture of calcaneus operative approach can provide for posterior articular facet the approach fully exposed widely, be difficult to fully expose sustentaculum tali through this approach, the program, and what rely on is experience and the technology of doctor, certain surgical field of view blind area is there is when certainly placing internal fixation screw outside to inside, cause screw placement position to produce deviation, occur some postoperative complications.
