If a patient with a heel fracture has not recovered after 65 days of conservative treatment, it may be due to insufficient functional exercises, poor fracture healing, or complication of infection. At this time, the patient should not be able to deal with it by themselves, but should return to the orthopedic department in time for follow-up, and actively cooperate with the doctor to take functional exercise, surgical treatment, application of anti-infection drugs and other treatments. The specific treatment measures are as follows: 1. Functional exercise: for some patients who are afraid of pain and do not exercise enough, it is necessary to strengthen the functional exercise at this time. At this time, it is suggested that patients can go to the professional rehabilitation physiotherapy department and ask the rehabilitation doctor to carry out functional exercise on the lesion. After exercising for a period of time, the patient can perform ankle flexion and extension activities at home by himself. 2. Surgical treatment: For some patients with obvious slow healing or even deformed healing, surgical treatment is needed. At this time, the fracture end needs to be thoroughly cleaned up, and sometimes it is also necessary to osteotomize the relevant part of the bone. After that, it is necessary to cooperate with bone grafting and internal fixation implantation and other treatments in order to orthopedize the localization and promote the healing of the fracture. 3. Application of anti-infective drugs: for patients with local infections, it is necessary to carry out bacterial culture of local secretions, and then according to the results of the application of some sensitive antibiotics to carry out treatment, commonly used such as ceftriaxone sodium, cefotaxime sodium and other cephalosporin antibiotics. For patients with more serious lesions, surgical debridement of the affected area is also required. Patients with heel fracture who have not recovered after 65 days of conservative treatment need to be seen by a medical professional for evaluation and treatment.
