Chronic heel osteomyelitis is difficult to treat, and patients often go through years of repeated treatment without being cured, causing great pain to the individual. Since 2011, we have been treating chronic heel osteomyelitis with a thorough debridement, antibiotic bone cement filling, and flap repair of the wound with satisfactory results. The reasons for the difficulty in treating osteomyelitis of the heel are: (1) intravenous infusion of antibiotics does not always achieve an effective antibacterial concentration in the foci of infection. (ii) The heel bone is cancellous bone, and it is difficult to completely remove all bacteria hidden in the cancellous bone cavity during debridement, so it is easy to recur. ③The method of continuous irrigation is difficult to implement in the treatment of heel osteomyelitis because irrigation requires a closed cavity, and when osteomyelitis occurs in the heel, it usually results in a defect in the surrounding skin that prevents closure of the wound, so irrigation is not easily performed. ④Muscle flap filling is an effective treatment for osteomyelitis of the long bone, but there is a lack of available muscle tissue around the heel bone, and free transplantation of muscle tissue in the distal compartment requires complex microsurgical technical support that is not easily mastered by general practitioners. (5) Amputation of the infected bone segment and repair of the bone defect using bone transfer techniques are effective in the treatment of long bone osteomyelitis, but difficult to apply in the treatment of short heel osteomyelitis. For these reasons, osteomyelitis of the heel is often treated several times with poor results and often remains untreated for many years. The efficacy of antibiotic bone cement in the treatment of heel osteomyelitis is exact because of the following advantages of this method: ① thorough debridement: because of the postoperative filling and support of the bone cement and the guarantee of the skin flap covering the wound repair, there is no worry that the larger cavity formed after scraping the dead bone will affect the weight-bearing of the heel bone, so the infection of the soft tissue and bone can be removed thoroughly or even expanded. ②The temperature generated by the antibiotic bone cement after implantation in the toothpaste period can reach 70°, which can kill the bacteria remaining in the cancellous bone, and its slow release of antibiotics can continuously keep the heel bone in an antibacterial and bactericidal environment. ③The incision and wound are closed in time using microsurgical techniques to isolate the heel bone from the external environment, so it is not easy to recur. The method of thorough debridement + antibiotic bone cement filling + effective closure of the wound is an efficacious and easy to grasp method of treating heel osteomyelitis. Typical cases.
