Problems solved by technology

[0003] The current treatment method for the avulsion fracture of the Achilles tendon of the calcaneus is the percutaneous lag screw technique. The actual operation of the percutaneous lag screw technique is extremely difficult. Soft tissue impaction will affect the anatomical reduction, and the strong traction of the Achilles tendon can also cause The long-term bone fragments will be displaced again, so the tension band technique should be used to pass through the bone hole and use steel wires to neutralize the pulling force of the Achilles tendon

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Figure 5 As shown, the shape of the calcaneus 100 is irregular, and there are six sides: the upper side 101, the lower side, the front side, the back side, the inner side, and the outer side 102; .

[0024] Figures 1 to 5 As shown in the figure, a calcaneal locking plate applied to an avulsion fracture of the Achilles tendon, the calcaneal locking plate is an anatomical locking plate, including a calcaneal tuberosity locking part 1 that fits with the calcaneal tuberosity 103 , the locking portion 2 on the lateral surface of the calcaneus that fits on the lateral surface of the calcaneus 102 and the upper locking portion 3 on the upper surface of the calcaneus that fits on the upper surface of the calcaneus 101, the locking portion 1 of the tuberosity of the calcaneus and the upper locking portion 3 of the calcaneus, respect...

Abstract

The invention discloses a calcaneus locking plate applied to tendo calcaneus avulsion fracture. The calcaneus locking plate comprises a calcaneus tubercle locking portion fitted with calcaneus tubercle, a calcaneus outer side face locking portion fitted with the outer side face of calcaneus and a calcaneus upper face locking portion fitted with the upper face of calcaneus, the calcaneus tubercle locking portion and the calcaneus upper face locking portion are connected at two ends of the calcaneus outer side face locking portion respectively, a locking hole is formed in each of the calcaneus tubercle locking portion, the calcaneus outer side face locking portion and the calcaneus upper face locking portion, and multiple suture line holes for calcaneus suture lines to penetrate are formed in the calcaneus tubercle locking portion. The calcaneus locking plate can effectively fix calcaneus fracture blocks and resist traction of tendo calcaneus.

Description

technical field [0001] The invention relates to the technical field of bone locking plate manufacture, in particular to a calcaneal locking plate applied to Achilles tendon avulsion fracture. Background technique [0002] The calcaneus is the largest piece of the tarsal bone, and the Achilles tendon is connected to the calcaneus. Due to high-intensity exercise or other reasons, the calcaneus sometimes produces Achilles tendon avulsion fractures. [0003] The current treatment method for the avulsion fracture of the Achilles tendon of the calcaneus is the percutaneous lag screw technique. The actual operation of the percutaneous lag screw technique is extremely difficult. Soft tissue impaction will affect the anatomical reduction, and the strong traction of the Achilles tendon can also cause The long-term bone fragment will be displaced again, so it is necessary to use the tension band technique to pass through the bone hole and use the steel wire to neutralize the pulling fo...
