Problems solved by technology

Since the tibial calcaneal screw needs to cross three bones, the length is relatively long, and the positioning of the screw is only determined by the experience of the surgeon, so human error will inevitably occur, resulting in unsatisfactory screw positioning, which will affect the surgical effect, seriously failed operation

Abstract

The invention relates to a tibial talocalcaneal joint fusion screw placement guider which comprises a screw placement guider, wherein the screw placement guider comprises a guide plate and a mounting support; the guide plate is an arc-shaped strip plate, the guide plate comprises a front guide section, a middle arc-shaped section and a rear guide section, a 90-degree angle is kept between the front guide section and the rear guide section, the two ends of the middle arc-shaped section respectively bend for 90 degrees and are connected with the front guide section and the rear guide section, and screw placement mounting holes distributed in one row are distributed at the middle part of a plate; and the mounting support is U-shaped, and two tail ends of the U-shaped mounting support are hinged with the two sides of the guide plate. The guider provided by the invention can carry out accurate positioning on the bone surface of calcaneus, the operation is convenient, the tibia, ankle bone and calcaneus can be accurately connected together, and thus the operation success rate is improved.

Description

technical field [0001] The invention relates to the technical field of tibiotalar-calcaneal joint fusion, in particular to a guider for inserting tibial-talar-calcaneal joint screws and a method for using the same. Background technique [0002] Trauma of the ankle and hindfoot, joint disease, etc. can often lead to tibiotalar and tibiotalar calcaneal arthritis, and conservative treatment can only improve part of the symptoms. However, due to biomechanical imbalance, arthritis develops progressively, and the symptoms also aggravate progressively. It may also be accompanied by varus and valgus deformities of the ankle joint or hindfoot, and conservative treatment cannot obtain satisfactory results. At present, arthrodesis is the gold standard for the treatment of such diseases, through fusion of diseased joints to relieve pain and reconstruct a painless plantar foot. Tibiotalar heel fusion can fuse the tibiotalar heel joint and ankle joint at the same time, and solve the dise...
