Profile of Knee’s Bone and Joint Tuberculosis in Adults: About 33 Cases

The authors report toward a monocentric retrospective and descriptive study on a 08 year period, 33 cases of knee osteoarticular tuberculosis (OAT) of adult, certified by bacteriologic and/or histolological evidence proof of the sample (synovial biopsy) after a knee arthrotomy. There were 07 cases of arthritis and 26 cases of osteoarthritis. The treatment of knee OAT was medical (anti-tubercular poly-chemotherapy) on one year duration. The surgery was useful in front of some clinical presentations. After a minimum of 18 months, a functional evaluation was done following the Lequesne algo-functionnal index. None had signs of local recurrence testifying the adequacy of medical treatment, even if it is long and binding. The main of our case series is to establish an epidemiological, clinical and biological profile of the knee tuberculosis of adult and to research elements of prognosis through an analysis of results.

Evaluation of Lo＂wenstein-Jensen Medium Culture,MGIT 960 Culture and Different Specimen Types inDiagnosis of Bone and Joint Tuberculosis

Objective： The aim of this study was to evaluate L-J （Lo＂wenstein-Jensen） medium culture, MGIT 960 culture anddifferent specimen types in diagnosis of BJTB （bone and joint tuberculosis）. Methods：： Specimens of pus, caseous necrosis,tuberculous granuloma and sequestrum were collected from 52 BJTB patients. All specimens were cultured using both MGIT 960system and L-J medium; and all pus were amplified using real-time PCR to detect the presence of M. tuberculosis DNA. KeyFindings： A total of 191 specimens were collected. Granuloma had better chance to produce positive outcomes by L-J mediumculture, while for sequestrum MGIT 960 culture had higher yield, but there was no significant difference in the recovery rates amongdifferent types of specimen either by L-J culture （Z2 = 0.638, P = 0.888） or by MGIT960 culture （Z2 = 1.399, P = 0.706）. MGIT960culture had significantly higher recovery rate than L-J culture, With a combined culture and PCR-based test, the recovery rate of pusspecimen was significantly higher than that of either method alone （P 〈 0.05）. Conclusion： MGIT 960 culture is superior to L-Jculture in BJTB diagnosis; pus, sequestrum, granuloma and caseous necrosis are usable specimen for mycobacterial culture;combination of culture and molecular techniques can provide a better diagnostic significance.

Tuberculosis Arthritis of the Sternoclavicular Joint

Tuberculosis remains a public health problem in developing country particularly in Tunisia. Bone location of tuberculosis infection is increasing and is often misdiagnosed due to the weakness of clinical presentation in early stages. Sternoclavicular joint tuberculosis is rare and unusual location of this disease. However, antibiotherapy and surgical debridement is still the basis of treatment. We report a case of sternoclavicular joint tuberculosis with a follow up of four years. The patient was treated surgically and put under antibiotherapy during twelve months. The site was sterilized. We report this case to show that debridement and antibiotherapy still efficient in tuberculous bone affection no matters the location.

Tuberculosis of the Sternoclavicular Joint: Report of 3 New Cases Observed in Abidjan

The sternoclavicular joint is a rare site of osteoarticular tuberculosis. We now report three new cases of sternoclavicular tuberculosis. The report concentrates mostly on immunocompromised patients, notably two with HIV infection and one case marked by its acute onset which is rather original because, in this case, there was a swollen sternoclavicular joint with normal X-ray and it was the CT-scan which showed the lesions. The etiological diagnosis was made in the first case by polymerase chain reaction and in the second case by identification of Mycobacterium tuberculosis. In the third case, the diagnosis was presumptive and the outcome on anti-tuberculous drugs was satisfactory. Sternoclavicular joint tuberculosis is unusual;the painful swelling of that joint should lead to realize a performed imaging such as CT-scan.

Magnetic Resonance Imaging for Diagnosis and Analysis of Bone Tumors and Bone Tuberculosis

The purpose of the study is to explore the diagnostic value of magnetic resonance imaging in bone tuberculosis and bone tumors.Firstly,148 patients with bone tumor and bone tuberculosis were selected,74 cases in each group.Perform magnetic resonance imaging(MRI)examinations on all patients,relevant parameters were set and the changes in the value of the dispersion system were recorded to obtain T1-weighted imaging and T2-weighted imaging.The results showed that among 74 patients,41 cases were bone damage,38 cases were joint swelling,27 cases were sparse bone,10 cases were bone hyperplasia and 5 cases were dead bone and calcification.The imaging manifestations of bone tumors were 45 cases of fractures,26 cases of surrounding soft tissue infiltration,10 cases of hip duct enlargement and 11 cases of sacral foramen enlargement.After MRI diagnosis,the accuracy of diagnosing 74 cases of bone tumor was 100%,and the accuracy of diagnosing 65 cases of bone tuberculosis was 87.84%.The difference between the two groups was statistically significant(P<0.05).The diffusion sensitivity coefficient of MRI weighted imaging was 150 s/mm2,and there was no significant difference in ADC values between the two groups(P>0.05).When the diffusion sensitivity coefficient is 300 s/mm2,and the difference between the two groups was statistically significant(P<0.05).Therefore,MRI had a certain diagnostic value for bone tuberculosis and bone tumors,and MRI had a higher diagnostic value and richer information for bone tumors.Corresponding treatment can be performed to improve the prognosis.

Multitrack and multianchor point screw technique combined with the Wiltse approach for lesion debridement for lumbar tuberculosis

BACKGROUND The incidence of lumbar tuberculosis is high worldwide,and effective treatment is a continuing problem.AIM To study the safety and efficacy of the multitrack and multianchor point screw technique combined with the contralateral Wiltse approach for lesion debridement to treat lumbar tuberculosis.METHODS The C-reactive protein(CRP)level,erythrocyte sedimentation rate(ESR),visual analogue scale(VAS)score,oswestry disability index(ODI)and American Spinal Injury Association(ASIA)grade were recorded and analysed pre-and postoperatively.RESULTS The CRP level and ESR returned to normal,and the VAS score and ODI were decreased at 3 mo postoperatively,with significant differences compared with the preoperative values(P<0.01).Neurological dysfunction was relieved,and the ASIA grade increased,with no adverse events.CONCLUSION The multitrack,multianchor point screw fixation technique combined with the contralateral Wiltse approach for debridement is an effective and safe method for the treatment of lumbar tuberculosis.

One-stage total hip arthroplasty for advanced hip tuberculosis combined with developmental dysplasia of the hip:A case report

BACKGROUND A patient with advanced tuberculosis of the hip joint combined with Crowe type IV developmental dysplasia of the hip(DDH)and a drainage sinus is a rare condition.There are no previous reports of this condition,and it is a complex challenge for surgeons to develop a treatment scheme.CASE SUMMARY We report a 73-year-old male patient with severe hip pain and drainage sinus of the left hip for one month.Approximately 40 years ago,a drainage sinus occurred at the lateral left hip was healed at the local hospital with anti-infectious therapy.After the sinus healed,gradual pain occurred in the left hip for 40 years.Approximately one month prior,hip pain was sharply aggravated,and a drainage sinus reoccurred in the left hip.The X-ray and computed tomography examinations showed destruction of the head and neck of the left femur,as well as an acetabular deformity.The results of Mycobacterium tuberculosis antibody and Xpert were positive.Therefore,the patient was diagnosed with advanced TH combined with Crowe type IV DDH.After 22 d of treatment with anti-tuberculosis chemotherapy,the sinus healed,and the patient underwent one-stage total hip arthroplasty(THA)surgery consisting of debridement,osteotomy,and joint replacement.After surgery,the patient received anti-tuberculosis chemotherapy drugs for nine months,with no recurrent infection.After one year of follow-up,the Harris score of the patient increased from 21 pre-THA to 86.CONCLUSION Although drainage sinuses are a contraindication to one-stage THA,one-stage THA is still an effective and safe surgical method after the sinus heals.

One-stage Surgical Treatment for Thoracic and Lumbar Spinal Tuberculosis by Transpedicular Fixation, Debridement, and Combined Interbody and Posterior Fusion via a Posterior-only Approach

This study examined the clinical outcomes of one-stage surgical treatment for patients with spinal tuberculosis via a posterior-only approach. Twenty-four patients with thoracic or lumbar spinal tuberculosis whose lesions were confined to adjacent segments were admitted to our hospital and treated. The American Spinal Injury Association（ASIA） impairment scale was used to assess the neurological function. All patients were treated with one-stage surgical treatment via a posterior-only approach. The clinical efficacy was evaluated by the Japanese Orthopaedic Association（JOA） scores and oswestry disability index（ODI） of nerve function. Patients were evaluated preoperatively and postoperatively by measurement of spinal deformity using Cobb angle and radiological examination. All the patients were followed up for 13 to 27 months. They had significantly postoperative improvement in JOA score, ODI and ASIA classification scores. The kyphotic angles were significantly corrected and maintained at the final follow-up. Bone fusion was achieved within 4–12 months. It was concluded that one-stage surgical treatment via a posterior-only approach is effective and feasible for the treatment of spinal tuberculosis.

First Metatarsophalangeal Joint Arthrodesis: Comparison of Mesenchymal Stem Cell Allograft versus Autogenous Bone Graft Fusion Rates

With patients undergoing first time 1st metatarsophalangeal joint arthrodesis using graft material when it was required to fill cystic bone voids, we retrospectively compared the time to fusion (clinical and radiographic), and non-union rate between the patient’s own bone autograft (n = 62) versus a mesenchymal stem cell impregnated allograft group (n = 51). A third control group (n = 52) was included in which an end-to-end arthrodesis was performed and no graft interposition was used or necessary. The non-union rate was 4% (n = 2) in the control group, 5.9% (n = 4) in the autograft group, and 9.5% (n = 5) in the mesenchymal stem cell allograft group. The time for radiographic fusion was 6.46 weeks for the control group, 6.52 weeks for the autograft group, and 6.53 weeks for the mesenchymal stem cell allograft group. The difference in time to clinical and radiographic union and the non-union rate were not found to be statistically significant among all 3 groups. Patient comorbidities and their possible effects on union rates were also analyzed within the populations. Some comorbidities had statistically significantly non-unions within the population, notably smoking (p = 0.024) and Rheumatoid arthritis (p = 0.001), however the populations were fairly small. The use of allogeneic bone graft impregnated with mesenchymal stem cells yields a similar fusion rate as with the use of autologous bone graft harvested from the surrounding area. The allograft impregnated with mesenchymal stem cells is a viable alternative yielding similar results when local autogenous bone graft is not available, not obtainable, or conditions warrant its use.

A TETRACYCLINE LABELING STUDY OF SUBCHONDRAL BONE TISSUES IN OSTEOARTHRITIC HIP JOINT

Seven female patients (mean age of 56 years) with advanced hip joint osteoarthritis underwent total hip replacement. Four days before operation they were given oral tetracycline for two days. During operation specimens were taken from the white articular cartilage, the yellowish articular cartilage and the ivory bone together with their subchondral bone tissues. The undecalcified specimens were cut into 10 μm sections and observed under the fluorescence microscope. In all the specimens the following findings could be observed. 1. The osteoarthritic articular cartilage became thinner, with uneven surface and fissures. 2. The superficial and deep surfaces and the central part of the subchondral bone plate showed bright golden yellow fluorescence. It reflected extensive new bone formation. 3. The subchondral bone trabeculae also revealed bright golden yellow fluorescence on their peripheral borders, so trabeculae turned thicker obviously. 4. The marrow tissues between the bone trabeculae exhibited particulate or spherical bright golden yellow fluorescence, reflecting new bone formation in the marrow. The particulate and spherical bright golden yellow fluorescent materials might aggregate, enlarge and merge into large piece of new bone and they also fused with the neighbouring bone trabeculae. The aforementioned changes in the structure of the subchondral bone tissues increased greatly the mass in the osteoarthritic femoral head.

Periprosthetic joint infections in femoral neck fracture patients treated with hemiarthroplasty–should we use antibiotic-loaded bone cement?

BACKGROUND Hemiarthroplasty is the most common treatment in elderly patients with displaced intra-capsular femoral neck fracture(FNF).Prosthetic joint infection(PJI)is one of the most feared and frequent complications post-surgery because of the frail health status of these patients and the need for fast track surgery.Therefore,priorities should lie in effective preventive strategies to mitigate this burden.AIM To determine how much the implementation of the routine use of antibioticloaded bone cement(ALBC)as a relatively easy-to-apply amendment to the surgical practice reduces the infection rate in our hemiarthroplasty cohort.METHODS We retrospectively assessed all demographic,health status and treatment-related data of our FNF patients undergoing cemented hemiarthroplasty in the period from 2011 to 2017;241 patients were further analyzed after exclusion of patients with cancer-related sequelae and those who died before the end of the 1-year observation period.The PJI rate as diagnosed on basis of the Musculoskeletal Infection Society(MSIS)criteria 2011 was determined for each included patient and compared in function of the bone cement used for hip stem fixation.Patients were split into a group receiving a plain bone cement in the period from January 2011 to June 2013(non-ALBC group)and into a group receiving an ALBC in the period July 2013 to December 2017(ALBC group).Data analysis was performed with statistical software.We further calculated the cost-efficacy of the implementation of routine use of ALBC in the second group balancing the inhospital infection related treatment costs with the extra costs of use of ALBC.RESULTS In total 241 FNF patients who received cemented hemiarthroplasty in the period from January 2011 to January 2017 were eligible for inclusion in this retrospective study.There were 8 PJI cases identified in the ALBC group among n=94 patients,whereas 28 PJI cases were observed in the non-ALBC group among n=147 patients.The statistical analysis showed an infection risk reduction of 55.3%(in particular due to the avoidance of chronic delayed infections)in the ALBC group(95%CI:6.2%-78.7%;P=0.0025).The cost-evaluation analysis demonstrated a considerable cost saving of 3.500€per patient,related to the implementation of routine use of ALBC in this group.CONCLUSION Use of ALBC is a potent infection preventive factor in FNF patients receiving cemented hemiarthroplasties.It was further found to be highly cost-effective.

Objective:To explore the clinical value of dual energy CT(DECT)virtual noncalcium(VNCa)in the diagnosis of sacroiliac joint bone marrow edema(BME).Methods:A collection of 45 patients(21 males,24 females,and an average age of 34 years)who underwent MRI and DECT(Siemens Somatom definition force)examinations for the sacroiliac joints in our hospital from January 2019 to August 2020.After the DECT scan,the bone marrow pseudo-color map was obtained after VNCa processing.The bone marrow pseudo-color map was evaluated by two physicians.Take MRI test results as the gold standard,the application value of DECT VNCa technology in the diagnosis of sacroiliac joint BME was analyzed.Results:The positive predictive value(PPV),negative predictive value(NPV),sensitivity(Sen),specificity(Spe)and accuracy(Acc)of the qualitative diagnosis of iliac bone and sacral BME with DECT VNCa technology was:80.6%,85.2%,78.4%,86.8%,83.3%and 100%,64.9%,32.5%,100%,70.0%,respectively.The area of edema displayed by quantitative measurement of DECT VNCa image is smaller than the area measured by MRI image.The VNCa CT value(-71.66±72.97Hu)of the iliac edema area was higher than that of the non-edema area(-90.27±65.85Hu),and the VNCa CT value of the sacral edema area(-62.90±46.87Hu)was higher than that of the non-edema area(-101.08±134.02Hu),the best cut-off values(Cut-off values)for the quantitative diagnosis of iliac bone and sacral BME by VNCa are-66.40Hu and-50.60Hu,respectively.The curve of the receiver operating characteristic(ROC)of the iliac bone and sacrum area under the cure(AUC)is 0.720 and 0.706 respectively.There is a moderate negative correlation between the VNCa CT values of the ilium and sacrum in the edema area and the conventional CT values.Conclusion:The DECT VNCa technique has certain effectiveness in the diagnosis of sacroiliac joint BME,and its effectiveness in the diagnosis of ilium BME is better than sacrum.

Effect of different hip replacement methods under minimally invasive anterolateral approach on bone metabolism and joint pain in patients with femoral neck fracture

Objective: To explore the effect of different hip replacement methods under minimally invasive anterolateral approach on bone metabolism and joint pain in patients with femoral neck fracture. Methods: A total of 110 patients with femoral neck fracture who were treated in Ruijin Hospital North, Shanghai Jiaotong University School of Medicine between July 2015 and January 2017 were collected and divided into control group and observation group by random number table, each with 55 cases. Control group accepted half hip replacement under minimally invasive anterolateral approach, and observation group accepted total hip replacement under minimally invasive anterolateral approach. The differences in contents of bone metabolism and joint pain-related indexes were compared between the two groups before and after surgery. Results: Before surgery, serum contents of bone formation indexes, bone resorption indexes, inflammatory indexes and pain mediators were not statistically significant between the two groups. 1 month after surgery, serum bone formation indexes PINP, BAP and BGP contents of observation group were higher than those of control group;serum bone resorption indexes β-CTX and TRACP-5b contents were lower than those of control group;serum inflammatory indexes IL-1 and TNF-α contents were lower than those of control group;serum pain mediators 5-HT and PGE2 contents were lower than those of control group. Conclusion: Total hip replacement under minimally invasive anterolateral approach is more effective to promote the formation of bone formation/bone resorption balance and reduce the joint pain.
