Infectious and inflammatory bone diseases include a wide range of disease process, depending on the patient's age, location of infection, various causative organisms, duration from symtom onset, accompanied fracture or prior surgery, prosthesis insertion, and underlying systemic disease such as diabetes, etc. Bone infection may induce massive destruction of bones and joints, results in functional reduction and disability. The key to successful management is early diagnosis and proper treatment. Various radionuclide imaging methods including three phase bone scan, Ga-67 scan, WBC scan, and combined imaging techniques such as bone/Ga-67 scan, WBC/bone marrow scan add complementary role to the radiologic imaging modalities including plain radiography, CT and MRI. F-18 FDG PET imaging also has recently been introduced in diagnosis of infected prosthesis and chronic active osteomyelitis. Selection of proper nuclear medicine imaging method will improve the diagnostic accuracy of infectious and inflammatory bone diseases, based on understading of pathogenesis and radiologic imaging findings.

OBJECTIVETo evaluate indications and clinical results of total hip arthroplasties for degenerative hips with history of infection.

METHODSSeven cases of degenerative hip with history of infection underwent primary total hip arthroplasties, which involved 5 males and 2 females, with an average age of 45.8 years (range, 30 to 65 years). The quiescent period of infection were more than 10 years in all hips. According to Kim classification, 3 cases were of type I, and 4 of type II. The method to exclude active infection at the site of degenerative hips preoperatively was combination of physical examination, erythrocyte sedimentation rate and C-reactive protein level. The lateral incision was adopted in all cases, and all prosthesis were cementless. The clinical results of affected hips were assessed according to Harris hip score.

RESULTSThe follow-up was performed with the mean duration of 33.5 months (range, 21 to 44 months). No recurrence of infection, damage of nerve function or deep vein thrombosis of lower extremities occurred in all cases. The mean Harris hip scores improved from 44.5 points preoperatively to 84 points at the latest follow-up. No aseptic loosening of prosthesis or periprosthetic osteolysis were found at the latest follow-up.

CONCLUSIONTotal hip arthroplasties has good short term results for degenerative hips with history of infection. It is important to select indicated cases and rule out the possibility of active infection.

OBJECTIVETo evaluate the surgical indications and clinical effectiveness of different operative procedures in the treatment of lower lumbar tuberculosis.

METHODSFrom June 2001 to Oct 2008, 72 patients with lower lumbar tuberculosis were treated by different operative procedures. Including 38 males and 34 females, with an average age of 38.5 years old ranging from 16 to 70 years. The average duration of symptom was 6.8 months (ranging from 4 months to 2 years). A single vertebrae was involved in 10 patients,two contiguous vertebrae in 50 cases and three vertebrae in 12 cases. The average preoperative lordotic angle was 13.1 degree (ranging from -5.0 degrees to 34.0 degrees). Three different operative procedures included: (1) posterior debridement and posterolateral fusion and posterior instrumentation in 28 patients; (2) anterior radical debridement and anterior fusion and anterior instrumentation in 32 patients; (3) image-guided percutaneous drainage (PCD) of tuberculous abscesses in 12 patients. The selection of the procedure was made according to the degree of the lesions. The resolution of inflammatory process, bony fusion, correction of sagittal angles and JOA scores were used for evaluating the result of the surgery and the complications were analyzed.

RESULTSAll patients were followed up from 1.5 to 8.0 years (means 3.6 years). PCD was an effective treatment in 11 out of the 12 patients, one required surgical debridement and fusion. Among them, 57 (95%, 57/60) patients were treated by open operation showed successful bony fusion. The complications maily included common iliac vein injury in 3 patients, dural tear in 2 patients, they were all cured by intro-or postoperative treatment. The average immediate post-operative lordotic angle was 27.3 degree (35.0 degrees to 16.0 degrees), the average lordotic angle was 25.6 degree (33.0 degrees to 15.0 degrees) at final follow-up. Preoperatively and at final follow-up, JOA scores were respectively (15.2 +/- 3.4), (25.6 +/- 2.4) (P<0.01).

CONCLUSIONDifferent operative procedures should be selected to treat lower lumbar tuberculosis according to the degree of lesions. Aggressive surgical treatment was found helpful in the resolution of inflammatory process and correcting the loss of lordosis, preventing progression of kyphosis.

OBJECTIVE: Spondylitis is often chemotherapy resistant and requires long-term treatment. Without adequate chemotherapy, the outcome can be fatal or result in severe neurologic damage. Therefore, differentiating the etiology of spondylitis is very important, particularly in spontaneous cases. As the prevalence of tuberculosis in Korea has decreased in recent years, updated clinical research about spondylitis is warranted.METHODS: From April 2010 to March 2016, data from spondylitis patients were collected retrospectively. In total, 69 patients (51 with pyogenic spondylitis and 18 with tuberculous spondylitis) were included. Clinical data, laboratory findings including erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level, measurements of Cobb angles at the initial and final follow-up, and radiologic features on magnetic resonance imaging (MRI) scans were evaluated. To test differences between the pyogenic and tuberculous groups, numerical data were compared using the student’s t-test and Mann-Whitney U test, and categorical data were compared using the chi-square test and Fisher’s exact test.RESULTS: The patients’ mean age was 60.0 years. Male sex was slightly predominant (56.5%). There was no difference in mean age and sex between the two groups. The pyogenic group had a relatively higher proportion of immunocompromised patients. The peak CRP value was higher in the pyogenic group than in the tuberculous group (14.08 mg/dL and 8.50 mg/dL, respectively, p=0.009), whereas the ESR was not significantly different between the groups (81.5 mm/h and 75.6 mm/h, respectively, p=0.442). Radiologically, the presence of disc space sparing and vertebral body collapse differed between the groups. In the tuberculous group, the disc was more commonly preserved on contrast-enhanced MRI (50% and 23.5%, respectively, p=0.044), and vertebral body collapse was more common (66.6% and 15.7%, respectively, p < 0.001). The mean length of hospitalization was longer in the pyogenic group (56.5 days and 41.2 days, respectively, p=0.001). Four mortality cases were observed only in the pyogenic group. The most commonly isolated microorganism in the pyogenic group was Staphylococcus aureus (S. aureus) (methicillin susceptible S. aureus and methicillin resistant S. aureus [MRSA] in 8 and 4 cases, respectively).CONCLUSION: The clinical and radiological manifestations of spontaneous spondylitis differ based on the causative organism. Pyogenic spondylitis patients tend to have a higher CRP level and a more severe clinical course, whereas tuberculous spondylitis patients present with destruction of the vertebral body with disc sparing more frequently. The presence of MRSA is increasing in community-acquired spondylitis cases.

bone, skin, cornea and cardiovascular tissues. Allogenic bone grafts have possibility of transmission of hepatitis C, human immunodeficiency virus (HIV-1), human T-Cell leukaemia virus (HTLV), tuberculosis and other bacterias. The tissue bank should have a policy for obtaining information from the patient's medical report as to whether the donor had risk factors for infectious diseases. Over the past several years, improvements in donor screening criteria, such as excluding potential donor with "high risk" for HIV-1 and hepatitis infection, and donor blood testing result in the reduction of transmission of these diseases. During tissue processing, many allografts are exposed to antibiotics, disinfectants and terminal sterilization such as irradiation, which further reduce or remove the risk of transmitting diseases. Because the effectiveness of some tissue grafts such as, fresh frozen osteochondral grafts, depends on cellular viability, not all can be subjected to sterilization and processing steps and, therefore, the risk of transmission of infectious disease remains. This article is review of the transmission of considering infectious disease in allogenic bone transplantation and the processing steps of reducing the risk. The risk of viral transmission in allografts can be reduced in several standards. The most important are donor-screening tests and the removal of blood and soft tissues by processing steps under the aseptic environment. In conclusion, final sterilizations including the irradiation, can be establish the safety of allografts.]]>
