Description

Can splice type calcaneus orthopedic external fixation device

Technical Field

The utility model relates to the technical field of calcaneus fracture treatment, in particular to a splicing type calcaneus orthopedic external fixing device.

Background

Heel fracture (closed heel fracture, open heel fracture and intra-articular heel fracture) often causes complications such as heel collapse, abnormal healing, soft tissue infection, osteomyelitis and the like, and even serious injury patients need ankle joint fusion or amputation. Usually, the joint calcaneus fracture has poor recovery function, and the joint calcaneus fracture should be treated by the operation as much as possible. Taking the fracture of the calcaneus inside the joint as an example, due to the special anatomical position and the end load bearing function of the calcaneus, in high-energy injuries such as car accidents, falling and the like, a great deal of trouble is brought to the reduction of an orthopedist after a large amount of cancellous bone is wrapped by thin cortical bone. The normal heel and the soft tissue around the ankle joint are thinner and have higher tension, and the tension of the soft tissue at the injured part is higher. To date, none of the methods is universally applicable to all calcaneal fractures. Therefore, for the treatment of calcaneus fractures, the restoration of calcaneus function and the prevention of soft tissue infection are critical. However, in the existing incision reduction steel plate screw internal fixation, the internal implant occupies space and easily causes the problems of heel soft tissue swelling, infection and the like, but comminuted fracture is difficult to fix, the incision is large, the blood circulation recovery is influenced, the probability of developing osteomyelitis is high, and the adjustment is difficult after the deformity healing occurs. Although the emerging external fixation technology which is characterized by the ring fine needle can recover the calcaneus function and prevent complications such as soft tissue infection to a certain extent at present, the skin is easy to clamp and press, the waste of the structural space is large, the structure is complex, the weight is overlarge, and the normal recovery of the calcaneus function is influenced. For this reason, it is necessary to develop a splittable external calcaneus orthopedic fixation device that can solve the above problems.
