Abstract
The invention discloses a lateral malleolus bone plate. The lateral malleolus bone plate is made of titanium-nickel alloy, and comprises a head portion, a body portion and a tail portion. The head portion is in a spoon shape, and is matched with a lateral malleolus in shape, the middle of the head portion is thin, and the two sides of the head portion are thick; the body portion is a straight plate, and the tail portion is triangular and is provided with a circular corner in a chamfering mode. The head portion comprises six threaded holes and a plurality of suture holes, wherein every three threaded holes are formed in the same column, the threaded holes are arranged in a staggered mode to form the front column and the rear column, an acute angle is formed between the axis of the threaded holes and the bone plate, the axis of the threaded holes in the front column faces the inner upper portion, the threads holes in the rear column face the front lower portion, and the suture holes are free of threads, and are distributed between the threaded holes. The body portion is the straight plate, a lug is arranged on the portion, close to the head portion, of the rear side of the straight plate, a long kidney-shaped hole which is longitudinally designed is formed in the lug, and no threads are formed in the kidney-shaped hole. The tail portion is provided with 3-5 threaded holes, and a plurality of suture holes are formed between the threaded holes. In a lateral malleolus operation, screws can be prevented from entering joints, breakage of screws for the distal tibiofibular syndesmosis can be avoided, separation of the distal tibiofibular syndesmosis and the arthritis can be prevented, and use of the lateral malleolus bone plate and the suture in the operation are facilitated.
Description
Technical field
The present invention relates to a kind of blade plate of hospital orthopedics, particularly relate to the outer ankle blade plate of one of ankle operation outside Inferior tibiofibular joint place.
Background technology
Prior art China and foreign countries fracture of ankle can adopt Kirschner wire, tension band, blade plate screw to fix after the reset, and the forward and backward ligament of lower tibiofibula is shorter, directly repair difficulty, when the forward and backward ligament injury of lower tibiofibula, usually above Inferior tibiofibular joint, be screwed into the lag screw of a half-thread with the Inferior tibiofibular joint that is strained and fixed by fibula to tibia, allow the Inferior tibiofibular joint normal healing of damage recover the stability of Inferior tibiofibular joint.
Weak point is: existing external malleolus blade plate is not designed with Inferior tibiofibular joint screw hole especially, Inferior tibiofibular joint screw is inserted clinically by the plain bore on blade plate, because fibula is positioned at outside after tibia, screw hole direction can not change, difficulty inserted by Inferior tibiofibular joint screw, postoperative needs takes out Inferior tibiofibular joint screw, screw obtains early, then Inferior tibiofibular joint reparation does not complete, can occur that again shin calf is separated, affect ankle stability, screw obtains late, during patient's walking with load, Inferior tibiofibular joint screw extraction can be there is, and outer ankle screw designs is perpendicular to blade plate, screw easily enters joint, and blade plate is thicker, external malleolus apophysis goes out, skin is thin, blade plate is inserted and is easily occurred cutaneous necrosis afterwards.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of outer ankle blade plate, makes its clinical inserting facilitate and sew up, avoids screw to enter joint and Inferior tibiofibular joint screw extraction, Inferior tibiofibular syndesmosis split and arthritis can be prevented to occur.
For solving the problems of the technologies described above, the technical problem that the present invention mainly solves is to provide a kind of outer ankle blade plate, comprises head, body, afterbody three part; Contouring head and external malleolus match, and which is provided with multiple screwed hole and sewing hole; Body is straight plate, which is provided with multiple screwed hole, sewing hole and lug, and lug is set on rear side of straight plate near head place; Afterbody is triangular in shape and be rounded down, and which is provided with screwed hole and sewing hole; Its material is Ti-Ni alloy.
Preferably, described head is spoon shape, and intermediate thin both sides are thick, head includes six screwed holes and multiple sewing hole, screwed hole three string, two row before and after shifting to install into, screwed hole axis direction and blade plate acutangulate setting, and prostatitis screwed hole axis direction is top inwards, rank rear screwed hole direction forward downward, screw can be avoided to enter ankle joint, guarantee fully to fit with outer ankle.
Do and select, described head is provided with an external malleolus elliptical aperture, fully can avoid the interference between outer ankle blade plate and external malleolus.
Preferably, described lug place plane and its intersecting plane angle are greater than 90 ° and are less than 180 ° and lug is provided with a long waist shaped hole of longitudinally putting, without screw thread in hole, screw passes long waist shaped hole and is fixed on tibia, and can slide up and down along long waist shaped hole, can repair and prevent that shin calf combined separation makes that patient can do sth. in advance walking with load simultaneously and the unlikely lower tibiofibula hold-down screw that makes ruptures.
Preferably, described tailing screw flight axially bored line and straight plate are acute angle, make the fastness that increase afterbody is fixing, and the insertion of blade plate is convenient in triangular outline design.
Preferably, described sewing hole diameter 1 ~ 2mm, is convenient to temporary fixed in art and suturing soft tissue without screw thread.
The invention has the beneficial effects as follows: clinical inserting facilitates and sew up, and avoids screw to enter joint and Inferior tibiofibular joint screw extraction, Inferior tibiofibular syndesmosis split and arthritis can be prevented to occur and patient can be made to do sth. in advance walking with load.
