Description

Calcaneus fixing plate

Technical Field

The application relates to the field of orthopedic medical instruments, in particular to a calcaneus fixing plate.

Background

Calcaneal fractures are common fractures, accounting for 2% of total fractures, with 65% -75% of intra-articular fractures. The calcaneus fracture treatment method is various, the most common operation mode is an incision reduction and fixation operation mode, but wound infection and skin margin necrosis after the operation are always adverse factors affecting patients; and there is still a great deal of controversy for the internal fixation mode and access selection of calcaneus fracture in clinic. Non-operative treatment of calcaneal fracture often causes complications of calcaneal deformity, widening and height loss of calcaneal bones, subtalar arthritis and the like of patients. The minimally invasive small incision is adopted to treat calcaneal fracture, and indexes such as incision complications, excellent rate and the like are obviously superior to those of the traditional incision reduction treatment method in operation time.

The calcaneus bone fracture treatment method is characterized in that a calcaneus bone plate is adopted to reset and fix a fracture part in the calcaneus bone fracture treatment, and the loading talus process is used as a basis in the fixation, namely, screws are driven into the outer side wall of the calcaneus bone to penetrate through the minimally invasive calcaneus bone plate, and the calcaneus bone plate is fixed to the loading talus process on the inner side, so that the purposes of strong frame fixation and maintaining stability of a joint surface are achieved, and the step is the most critical step for treating calcaneus fracture.

However, the minimally invasive calcaneal plate used in the currently adopted tarsal sinus minimally invasive incision surgery has few nail holes and single direction, and the screws cannot be effectively fixed to the upturned talus in the fixing process, only can fix the inner side wall of the calcaneus along the set direction of the nail holes and can only be fixed to part of cortical bone, but the screws cannot penetrate through the cortical bone on the inner side wall of the calcaneus, otherwise nerves, blood vessels and tendons in the area are easily damaged.

Cortical bone is a layer of compact bone with hard bone surface, and the more cortical bone the screw is fixed to, the stronger the fixation strength, whereas if only fixed to part of cortical bone, the fixation strength is not strong enough, resulting in a delay in the load bearing time of the patient, increasing the recovery time, and possibly also affecting the prognosis function.

Therefore, the improved minimally invasive heel bone plate which can easily fix the talus processus, ensure the fixation of the heel bone plate to be firm and accelerate the postoperative recovery of a patient is necessary.
