Description
Technical Field
The invention relates to the field of medical instruments, in particular to a water chestnut varus osteotomy orthopedic guide device.
Background
Talipes equinovarus (equinovarus) refers to a horseshoe-shaped varus, which is classified into congenital deformity and acquired varus, and is the most common foot deformity. The formation of talipes equinovarus is mainly caused by unbalanced muscle force of feet, and bone joint deformity is formed after muscle imbalance is long, so that the deformity is more serious due to load bearing on the basis of the deformity. Equinovarus deformity consists of three factors, foot drop, varus and adduction. The aim of the equinovarus orthopaedics is to establish a painless and weight-bearing metatarsal walking foot, the force line between the foot and the lower leg is very critical, and the ideal force line is that the foot is in a flexion-extension neutral position, 5 degrees of external rotation and 5 degrees of eversion relative to the lower leg after the orthopaedics. The operation is usually wedge osteotomy of calcaneus, followed by calcaneal tendon elongation (multi-level section cutting off the achilles tendon to correct foot drop deformity caused by achilles tendon contracture), and metatarsal aponeurosis cutting off (cutting off the tense section of the metatarsal aponeurosis to correct plantarflexion and adduction of the forefoot) according to the force distribution of plantar surface in neutral position.
The accuracy of the calcaneus eversion osteotomy determines the effect of calcaneus correction after the osteotomy is everted and the treatment of later calcaneus healing. The operation steps are as follows: (1) an arc incision was made parallel to the fibula longissimus tendon at the posterior and inferior aspect of the tendon, exposing the lateral aspect of the foot. Retracting the upper edge of the incision to expose the tendon sheath of the long fibula, and peeling the calcaneal periosteum from the upper side, the lateral side and the lower side of the superior part; (2) the wedge-shaped osteotomy is performed in parallel to the fibula long tendon at the rear lower part close to the fibula long tendon, and the bone wedge is removed; (3) the inner cortex is fractured by manual force, and the wedge-shaped osteotomy gap is closed; further enabling the foot dorsiflexion to resist the tension of the achilles tendon and enabling the osteotomy area to be sealed; (4) two 6-7mm hollow compression screws are arranged in the bone cutting surface to be fixed. The key points of the operation include: (1) the angle of the osteotomy wedge is based on the orthopedic angle measured before the operation; (2) the bone wedge must reach the medial cortex of the calcaneus but not penetrate; (3) the osteotomy surface is smooth so as to be closed stably; (4) the two screws are perpendicular to the osteotomy surface and are evenly distributed. The technical points fail to satisfy the condition that the effect of osteotomy and orthopedic treatment and the healing of the osteotomy face bone are influenced.
At present, in clinical application, the calcaneus osteotomy level and the inner side intersection position of the osteotomy level can be estimated only by means of visual inspection and operation experience, the screw is placed and temporarily fixed by a Kirschner wire, and the position is fixed by implanting a hollow screw after the position is confirmed to be satisfied by repeated adjustment of perspective. Therefore, the deviation of the calcaneus osteotomy level and the defect of the calcaneus fusion line and the position of the screw are inevitably caused, the operation time is prolonged, and the operation treatment effect is poor, and even the calcaneus fusion operation fails.
The calcaneal tendon lengthening operation and the metatarsal aponeurosis cutting operation are soft tissue loosening operations, and the correction of residual foot drop deformity and plantarflexion and adduction deformity of the forefoot after the calcaneal eversion osteotomy fusion is mostly achieved by partially cutting off the achilles tendon or the metatarsal aponeurosis. The operation difficulty is relatively small, but the degree of the loosening and whether the stress condition of the sole can be evenly distributed when the sole is in the bending and stretching neutral position, the outward rotation of 5 degrees and the outward rotation of 5 degrees relative to the crus when the weight is loaded after the loosening determine the effect of the operation and the rehabilitation of the patient. In the current clinical application, the correction effect of the foot bottom loading plane after the operation can be estimated only according to the visual inspection and the hand feeling of an operator, so that the operation treatment effect is poor, the gait is abnormal and the local soft tissue is abraded due to the large local stress of the foot bottom when the patient walks after the operation, and the rehabilitation of the patient is finally influenced.
