Knee joint introversion and extroversion osteotomy orthopedic guide plate and manufacturing method thereof

Abstract

The invention discloses a knee joint introversion and extroversion osteotomy orthopedic guide plate and a manufacturing method thereof. The knee joint introversion and extroversion osteotomy orthopedic guide plate is prepared through the manufacturing method of the knee joint introversion and extroversion osteotomy orthopedic guide plate. A finished product of the knee joint introversion and extroversion osteotomy orthopedic guide plate comprises an osteotomy orthopedic guide plate body, a first osteotomy guide groove, a second osteotomy guide groove and a kirschner wire positioning guide column; the osteotomy orthopedic guide plate body is attached to the surface of a bone on the affected side; the first osteotomy guide groove and the second osteotomy guide groove are both formed on the osteotomy orthopedic guide plate body and coincided with a determined osteotomy angle and a determined osteotomy position; and the kirschner wire positioning guide column is installed at the needle inserting position of the osteotomy orthopedic guide plate body. According to the invention, the personalized osteotomy guide plate for a patient can be manufactured, knee joint introversion and extroversion can be accurately corrected, the force lines of the lower limbs on the two sides can be guaranteed, and the overall length of the lower limbs on the two sides can be recovered.

Description

technical field [0001] The invention relates to the field of design and processing of orthopedic auxiliary tools, in particular to a knee joint valgus osteotomy orthopedic guide plate and a manufacturing method thereof. Background technique [0002] Knee varus is a common orthopedic disease, often secondary to rickets, poliomyelitis, trauma and infection and other destructive diseases, resulting in deformity of the femur or tibia, changing the line of force of the lower limbs, resulting in an imbalance in the length of the lower limbs, resulting in Extremity pain, abnormal gait and appearance, etc. Knee valgus deformity can choose different treatment methods according to the patient's age and deformity. For example, patients with young age and mild deformity can be treated with manual therapy, brace or splint correction, elevated sole correction, and manual fracture. Patients with severe valgus genu deformity require surgical osteotomy for correction. Currently commonly us...

Problems solved by technology

Traditional orthopedic surgery is measured and calculated on X-ray films. Due to the relationship between X-ray projection angles, the accuracy is not good. In addition, in two-dimensional images, the deformity angles of other planes other than the frontal plane cannot be measured and estimated, which will affect the correction. In fact, limb deformities are multi-directional and multi-plane deformities in the true sense; traditional osteotomy orthopedic surgery is difficult to correct in three-dimensional space, so traditional osteotomy orthopedic surgery has obvious deficiencies in accuracy

In addition, in the process of traditional osteotomy orthopedic surgery, it is often necessary to rely on the guide pin positioning, the operator's personal experience and the continuous observation and adjustment of the X-ray machine to perform the correction, which prolongs the operation time, may increase surgical complications, and affect the surgical effect
