Description
Technical field
This utility model relates to orthopaedics therapy assistive device field, and nail steel plate is put in especially a kind of sustentaculum of talus locking.
Background technology
Fracture of calcaneus is modal fracture of tarsus, account for 60% of fracture of tarsus, wherein 75% involves subtalar joint, after operative treatment recovers, subtalar joint face anatomical reduction is the main purpose of intraarticular calcaneus fractures, but have more complication, so there is more scholar to propose the concept of minimally-invasive treatment fracture of calcaneus due to open reduction.In current treatment, due to the particularity of calcaneus anatomical structure, sustentaculum tali is the important fixing point in Fracture internal fixaiion, but how to put the difficult point of following closely and becoming in operation accurately.In order to deepen the understanding to calcaneus anatomic form further, improve fixing degree of accuracy.
Sustentaculum of talus be the anterior and body of calcaneus to the inside and the bone projection of top, sclerotin is finer and close.Around sustentaculum tali, tendon and ligament are a lot, and have strong joint capsule attachment, therefore in fracture of calcaneus, sustentaculum tali is seldom shifted simultaneously.So in order to make the posterior joint facial bone block after reset effectively be fixed, sustentaculum tali becomes the fixing important fulcrum of screw.The fixing of screw often needs two, interior outside fulcrum, and calcaneus lateral wall is thinner, because fracture causes outside posterior articular facet subsides, also cause lateral wall damaged, be difficult to the stop becoming internal fixtion, independent screw is fixed, once stressed, easily there is the loss resetted in articular surface.
Traditional method is application outside plate, manufactures the effective fulcrum of posterior articular facet in lateral wall by 3 fixation principle.
Summary of the invention
The purpose of this utility model is that providing a kind of sustentaculum of talus to lock puts nail steel plate, to overcome the deficiency of traditional method.This utility model, by studying the anatomy relationship of sustentaculum of talus and lateral wall, inquires into the feasibility that the outside sidewall of sustentaculum of talus puts nail, provides a kind of sustentaculum of talus to lock and puts nail steel plate.
The technical solution of the utility model is:
Nail steel plate is put in a kind of sustentaculum of talus locking, it is characterized in that comprising first puts nail steel plate 1, which is provided with first and puts nail 3, second and put nail 4 and the 3rd and put nail 5, also comprise to put with first follow closely that steel plate 1 mirror image arranges second put and follow closely steel plate 2.
Described first centrage and first putting nail 3 is put and followed closely steel plate 1 planar horizontal angle α is 15 degree to 18 degree.Be preferably 16.3 degree.
Described second centrage and first putting nail 4 puts that to follow closely steel plate 1 vertical.
Described 3rd centrage and first putting nail 5 is put and followed closely steel plate 1 planar horizontal angle β is 8 degree to 12 degree.Be preferably 9.2 degree.
Described first centrage and first putting nail 3 is put and followed closely steel plate 1 plane orthogonal angle γ is 6 degree to 10 degree.Be preferably 8 degree.
Described second centrage and first putting nail 4 is put and followed closely steel plate 1 plane orthogonal angle δ is 6 degree to 10 degree.Be preferably 8.1 degree.
Described 3rd centrage and first putting nail 5 is put and followed closely steel plate 1 plane orthogonal angle ε is 4 degree to 6 degree.Be preferably 4.8 degree.
Described first puts nail 3, second puts nail 4 and the 3rd and puts nail 5 spaced set.
The beneficial effects of the utility model are:
Sustentaculum of talus locking of the present utility model is put nail steel plate and effectively can be avoided the complication of outside otch, obtain the stable fixing of screw, being exposed, making operative approach otch little, without the need to exposing posterior tibial vessels nerve during operation technique by inner side sustentaculum tali approach.
Sustentaculum of talus of the present utility model locking puts nail steel plate in the lower secondary bone injury of the anterior forming energy of calcaneus, calcaneus front portion is greatly alleviated by the degree undermining displacement, sustentaculum of talus of the present utility model locking is put nail steel plate and one piece, front screw is fixed to calcaneus front portion can be firmly fixed, due to the angle stability of locking steel plate, so in fixing posterior articular facet, rear two pieces of screw stability also can obtain reasonable guarantee.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described:
As Fig. 1 to 5, nail steel plate is put in the locking of a kind of sustentaculum of talus, is to comprise first to put nail steel plate 1, which is provided with first and puts nail 3, second and put nail 4 and the 3rd and put nail 5, also comprise to put with first follow closely that steel plate 1 mirror image arranges second put and follow closely steel plate 2.
First centrage and first putting nail 3 is put and followed closely steel plate 1 planar horizontal angle α is 15 degree to 18 degree.Be preferably 16.3 degree.
Second centrage and first putting nail 4 puts that to follow closely steel plate 1 vertical.
