Ectropion is the most common forefoot deformity, manifested as [medial bulge of the toes and widening of the forefoot, which causes local swelling and pain due to friction between the shoe and the [medial bulge of the metatarsal head, at which point it becomes [capsulitis. The symptoms can be aggravated by wearing narrow shoes and walking. After ectropion, the weight-bearing function of the toe is reduced and the weight is shifted outward, which often produces forefoot plantar pain. In the past, neither patients nor doctors paid enough attention to it. As people’s aesthetic interests continue to change and improve, [valgus is also receiving increasing attention, and more and more people are requesting [valgus correction surgery. However, there are more than 100 types of ectropion correction procedures reported in the literature, how to choose the right procedure for each patient? The following principles can be used for reference. I. The degree of valgus is the main basis for selecting surgery. [The degree of valgus can be determined by measuring the valgus angle and the 1st and 2nd intermetatarsal angles on the frontal and lateral radiographs of the foot. The angle of valgus in normal people is 15 degrees, the 1.2 intermetatarsal angle is 9 degrees, more than this degree is abnormal, where the intermetatarsal angle is a dividing line, less than 15 degrees can be corrected by simple soft tissue surgery, short surgery time, small trauma, fast recovery after surgery; more than 15 degrees need to perform more complex osteotomy orthopedic surgery, very serious deformity may need to perform multiple osteotomy, the surgery is more complex, the recovery time is longer The surgery is more complicated and the recovery time is longer. Second, the patient’s expectations of the surgery must be considered. [In cases where there is no co-morbidity, the deformity is only a deformity, and in cases of combined [capsulitis, pain affects shoe wear and walking. Usually, young patients, especially female patients, require not only pain relief, but also correction of the deformity and the ability to wear their favorite shoes, which is common in large cities and developed areas, and more complex osteotomy orthopedic surgery is required; elderly patients have low requirements, a certain degree and time to relieve pain can be, you can choose a simple surgery, or even minimally invasive surgery or microporous surgery, without hospitalization, can also be completed on an outpatient basis. The procedure can be done on an outpatient basis without hospitalization. Third, affordability. After osteotomy orthopedic surgery, the osteotomy must be fixed, equivalent to the fixation of the fracture, methods such as plaster fixation, needle fixation, screw fixation and the latest special screws and fixators fixation, new technology fixation can make the operation easier, higher success rate, less pain, faster recovery, but the cost is expensive. Fourth, the academic and technical level of the doctor The academic level of the doctor is the depth and breadth of understanding of the disease and its treatment; the technical performance of the doctor is the degree of proficiency in mastering a certain kind of surgery. Doctors must clearly identify the pathological types of ectropion, master the indications, advantages and disadvantages of different surgical methods and operation techniques, and determine the surgical plan with the actual situation of the patient. V. Surgical instruments and equipment support. [Ectropion correction is a fine surgery, can be said to be “millimeter” and “degree” surgery, special surgical instruments are essential, especially the application of new technologies, more inseparable from the precise surgical instruments and fixed materials, otherwise the operation is difficult to achieve Otherwise, the operation will be difficult to achieve perfection. But not all hospitals have this condition. In short, [ectropion correction is never as simple as commercial hype suggests, and minimally invasive surgery should never be narrowly focused on the concept of small incisions! Excessive pursuit of small incisions can increase the chances of nerve and tendon damage. Based on the experience of treating a large number of patients, bony orthopedic surgery has the best results. Patients and physicians should integrate all of the above factors and choose an individualized treatment plan, as the saying goes, within limits.
