Short-term and Long-term Efficacy Evaluation of Drug-Loaded Osteoset Artificial Bone Grafting Fusion in the Treatment of Sacroiliac Joint Tuberculosis.

Objective: To analyze the short-term and long-term efficacy of Osteoset artificial bone graft fusion mixed with rifampicin for injection in the treatment of sacroiliac joint tuberculosis. Methods: A retrospective analysis was carried out on 70 patients diagnosed with sacroiliac joint tuberculosis who were admitted and underwent surgical treatment in our orthopedics department between April 2014 and May 2020. The patients were divided into three groups based on the different bone graft materials used: autogenous bone graft group (25 cases), simple lesion removal group (18 cases), and drug-loaded calcium sulfate bone graft group (27 cases). General information and surgical details of the three groups were compared. Sacroiliac X-ray and CT scans were performed at regular intervals to record pre- and post-treatment erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, bone graft fusion rates at 6, 12, and 18 months post-surgery, Majeed score for functional evaluation, and postoperative complications. Results: There was no statistically significant difference in operation time, intraoperative bleeding, and intraoperative pus removal volume among the three groups of patients (P > .05). Postoperatively, 70 patients were followed up, and the serum levels of ESR and CRP in all three groups of patients were significantly reduced at 3 months after surgery (P < .05). In the autogenous bone graft group, the bone graft fusion rates were 24.00% (6/25) at 6 months postoperatively, 76.00% (18/25) at 12 months, and 96.00% (24/25) at 18 months. In the simple lesion removal group, the bone graft fusion rates were 16.67% (3/18) at 6 months postoperatively, 27.78% (5/18) at 12 months, and 55.56% (10/18) at 18 months. In the drug-loaded calcium sulfate bone graft group, the bone graft fusion rates were 18.52% (5/27) at 6 months postoperatively, 55.56% (15/27) at 12 months, and 81.48% (22/27) at 18 months. In the autogenous bone graft group, the postoperative Majeed score averaged (91.47±4.13) points, with 13 cases rated as excellent and 10 cases rated as good, resulting in an excellent and good rate of 92.00% (23/25). The Majeed scores at 6, 12, and 18 months postoperatively were (67.19±4.22) points, (80.28±5.83) points, and (91.47±4.13) points, respectively. Among them, there were 4 excellent and 3 good cases at 6 months postoperatively, with an excellent and good rate of 28.00% (7/25). At 12 months postoperatively, there were 8 excellent and 10 good cases, with an excellent and good rate of 72.00% (18/25). At 18 months postoperatively, there were 13 excellent and 10 good cases, with an excellent and good rate of 92.00% (23/25). In the simple lesion removal group, the Majeed scores at 6, 12, and 18 months postoperatively were (59.17±3.95) points, (69.84±5.16) points, and (76.22±8.76) points, respectively. There were 2 excellent and 2 good cases at 6 months postoperatively, with an excellent and good rate of 22.22% (4/18). At 12 months postoperatively, there were 4 excellent and 3 good cases, with an excellent and good rate of 38.89% (7/18). At 18 months postoperatively, there were 5 excellent and 5 good cases, with an excellent and good rate of 55.56% (10/18). In the drug-loaded calcium sulfate bone graft group, the Majeed scores at 6, 12, and 18 months postoperatively were (63.24±4.17) points, (77.39±5.50) points, and (86.64±7.03) points, respectively. There were 3 excellent and 3 good cases at 6 months postoperatively, with an excellent and good rate of 22.22% (6/27). At 12 months postoperatively, there were 9 excellent and 7 good cases, with an excellent and good rate of 59.26% (16/27). At 18 months postoperatively, there were 10 excellent and 12 good cases, with an excellent and good rate of 81.48% (22/27). The Majeed scores for all three groups of patients showed a significant increase in the three follow-up evaluations compared to pre-treatment (P < .05). Conclusion: Drug-loaded Osteoset artificial bone graft fusion is a safe and effective method for treating bone defects after the debridement of sacroiliac joint tuberculosis lesions. It has fewer postoperative complications and achieves bone graft fusion in a shorter time compared to simple lesion removal methods.

Bilateral hand dactylitis: An unusual presentation of the great imitator: Tuberculosis.

The incidence of tuberculosis in developed countries has decreased over the years due to the use of effective tuberculosis drugs and improvements in socio-economic conditions. However, with the ease of global transport and increased travel to countries with high tuberculosis prevalence, the reduction in extrapulmonary tuberculosis cases has been less significant compared with the overall decrease in tuberculosis cases. Extrapulmonary tuberculosis can manifest in a variety of ways. Tuberculous dactylitis, a rare form of tuberculous osteomyelitis, was first described by Rankin in 1886. It mainly affects the short tubular bones in the hands and feet of children and is sometimes called 'spina ventosa'. A 42-year-old male patient initially presented to an external centre reporting swelling and pain in the hand joints of one year's duration. Despite one year of treatment with leflunomide and methylprednisolone (16 mg) and a history of methotrexate use during this period, he experienced no improvement. The patient's condition worsened after the start of sulfasalazine. Dermatological examination was performed due to the presence of haemorrhagic crusted papules and plaques on the ventral surface of both hands. A wound culture was taken, but no bacterial growth was observed. One week after the initial evaluation, the patient complained of persistent foul-smelling nasal discharge, which led to an evaluation by the infectious disease department. At this time, the Quantiferon test was positive. Mycobacterial culture on Days 1 and 3 showed growth of the Mycobacterium tuberculosis complex.

Unveiling foot tuberculosis as an under-recognized source of foot pain.

PURPOSE: Foot tuberculosis is a rare form of osteoarticular tuberculosis, accounting for less than 1% of cases. It presents unique diagnostic challenges due to its nonspecific clinical features and overlapping symptoms with other conditions. This study aimed to investigate the clinical presentation, radiographic findings, and prognosis of foot tuberculosis, with the goal of improving early recognition and appropriate intervention. METHODS: A prospective study was conducted between November 2016 and July 2021, involving 39 patients diagnosed with foot tuberculosis. Clinical examinations, laboratory tests, X-rays, and MRI evaluations were performed to aid in the diagnosis. Biopsy was conducted on patients with radiological lesions. Patients were treated with an 18-month course of antitubercular therapy (ATT). Foot Function Index (FFI) scores were recorded before and after treatment. Statistical analysis was conducted to assess factors impacting prognosis. RESULTS: Unilateral foot involvement was observed in all patients, with a male predominance (61.5%) and a mean age of 31.3 years. The most common symptoms were pain and edema, with sinus tracts present in 17.9% of patients. Radiographic findings showed cystic and sclerotic lesions, with the "spina ventosa" appearance primarily affecting the metatarsal bones. MRI played a valuable role in early detection. Histopathological examination confirmed tuberculosis in all cases, and acid-fast bacilli were found in 23% of patients. Most patients (79.4%) responded well to ATT without requiring surgery. Factors such as high initial ESR, delayed ATT initiation, multiple lesions, and tarsal involvement were associated with unfavourable outcomes. CONCLUSION: Foot tuberculosis presents with nonspecific symptoms, leading to misdiagnosis and delays in appropriate treatment. Clinical examination, radiographic evaluation, and biopsy are essential for accurate diagnosis. Early initiation of ATT is crucial for favourable outcomes. Factors such as high initial ESR, delayed treatment initiation, multiple lesions, and tarsal involvement negatively impact prognosis. This study highlights the importance of recognizing foot tuberculosis and provides insights into its clinical presentation, radiographic features, and treatment outcomes, facilitating timely intervention and improved patient management.

Concomitant methicillin-resistant Staphylococcus aureus infection in tubercular sacroiliitis masquerading as anti-tubercular drug resistance: Role for molecular diagnosis.

A 23-year-old female on anti-tubercular therapy for tuberculous sacroiliitis presented with right sided gluteal and thigh abscess. Suspecting treatment failure, surgical evacuation of purulent material was done. The bacteriological isolation showed positivity for methicillin-resistant Staphylococcus aureus. Although the microbiological and histopathology examination of the specimen were negative for tubercular isolates, the cartridge based -nucleic acid amplification tests revealed positive genes for Mycobacterium tuberculosis and additional primers showed sensitivity for rifampicin and isoniazid. She was adequately treated with vancomycin for six weeks and anti-tubercular drugs for eight months and followed till the bony ankyloses at 18 months. This is a rare case based scenario wherein concomitant staphylococcal infection in tubercular sacroiliitis masqueraded as anti-tubercular drug resistance. The cartridge-based nucleic acid amplification test for tuberculosis is a rapid and sensitive modality in identifying mycobacteria even mixed infections and also determine drug resistance. There are fewer consensuses in the literature regarding the drugs and duration of anti-tubercular regime for tuberculous sacroiliitis with most regimes using four drugs between six to eighteen months.

Diagnostic efficiency of Xpert MTB/RIF assay for osteoarticular tuberculosis in patients with inflammatory arthritis in China.

BACKGROUND: Both osteoarticular tuberculosis (OA-TB) and inflammatory arthritis can lead to osteoarticular structural damage. These conditions exhibit similar symptoms, physical signs, and imaging features. Rapidly and accurately diagnosing OA-TB in patients with inflammatory arthritis presents a challenge to clinicians. Xpert MTB/RIF (Xpert) has been endorsed by the World Health Organization (WHO) as a rapid diagnostic tool for diagnosis of pulmonary and extrapulmonary TB. This study was designed to investigate diagnostic efficiency of Xpert for OA-TB in patients with inflammatory arthritis in China. METHODS: A total of 83 consecutive patients with inflammatory arthritis and suspected OA-TB were enrolled prospectively from June 2014 to May 2018. Demographic, clinical, and biological data were recorded. Xpert assay, smear microscopy examination (smear), BACTEC MGIT 960 (MGIT 960), pathological examination, and T-SPOT.TB test were performed for each patient who received operations. Diagnostic efficiency of Xpert was evaluated based on a composite reference standard (CRS). RESULTS: A total of 49 out of 83 patients with inflammatory arthritis and suspected OA-TB received operations, and 49 specimens were obtained during operations. According to CRS, 36 out of 49 patients with inflammatory arthritis were diagnosed with OA-TB, and 13 were not affected by the condition. Sensitivity of Xpert assay, smear, MGIT 960, pathological examination, and T-SPOT.TB test reached 66.70% (24/36), 25.00% (9/36), 30.55% (11/36), 47.22% (17/36), and 80.55% (29/36), respectively. Specificity of Xpert assay, smear, MGIT 960, and pathological examination was all 100% (13/13). Specificity of T-SPOT.TB test was 53.84% (7/13). Sensitivity of Xpert was higher than that of smear, MGIT 960 and pathological examination, but the sensitivity of Xpert was lower than that of T-SPOT.TB. Sensitivity of Xpert was statistically different from that of smear and MGIT 960 (P<0.001, P = 0.002), but the sensitivity of Xpert was not significantly different from that of pathological examination and T-SPOT.TB (P = 0.096, P = 0.181). Specificity of T-SPOT.TB was less than that of Xpert, smear, MGIT 960, and pathological examination, and the difference between them was statistically significant (P = 0.015). Among the 27 OA-TB patients with smear negative results, Xpert had the highest sensitivity, but sensitivity of Xpert was not significantly different from that of pathological examination and T-SPOT.TB (P = 0.413, P = 0.783). 2 of 36 OA-TB patients exhibited RIF resistance. Xpert was concordant with MGIT 960-based drug susceptibility testing (DST) in detecting rifampin (RIF) resistance. CONCLUSIONS: Xpert is an efficient tool with high sensitivity and specificity for OA-TB diagnosis in patients with inflammatory arthritis in high-TB prevalence countries. Compared with conventional methods, Xpert has two advantages: one is fast, and the other is able to provide RIF resistance information simultaneously.

Delays in the diagnosis and treatment of bone and joint tuberculosis in the United Kingdom.

AIMS: Tuberculosis (TB) infection of bones and joints accounts for 6.7% of TB cases in England, and is associated with significant morbidity and disability. Public Health England reports that patients with TB experience delays in diagnosis and treatment. Our aims were to determine the demographics, presentation and investigation of patients with a TB infection of bones and joints, to help doctors assessing potential cases and to identify avoidable delays. PATIENTS AND METHODS: This was a retrospective observational study of all adults with positive TB cultures on specimens taken at a tertiary orthopaedic centre between June 2012 and May 2014. A laboratory information system search identified the patients. The demographics, clinical presentation, radiology, histopathology and key clinical dates were obtained from medical records. RESULTS: A total of 31 adult patients were identified. Their median age was 37 years (interquartile range (IQR): 29 to 53); 21 (68%) were male; 89% were migrants. The main sites affected were joints (10, 32%), the spine (8, 26%) and long bones (6, 19%); 8 (26%) had multifocal disease. The most common presenting symptoms were pain (29/31, 94%) and swelling (26/28, 93%). 'Typical' symptoms of TB, such as fever, sweats and weight loss, were uncommon. Patients waited a median of seven months (IQR 3 to 13.5) between the onset of symptoms and referral to the tertiary centre and 2.3 months (IQR 1.6 to 3.4.)) between referral and starting treatment. Radiology suggested TB in 26 (84%), but in seven patients (23%) the initial biopsy specimens were not sent for mycobacterial culture, necessitating a second biopsy. Rapid Polymerase Chain Reaction-based testing for TB using Xpert MTB/RIF was performed in five patients; 4 (80%) tested positive for TB. These patients had a reduced time between the diagnostic biopsy and starting treatment than those whose samples were not tested (median eight days versus 36 days, p = 0.016). CONCLUSION: Patients with bone and joint TB experience delays in diagnosis and treatment, some of which are avoidable. Maintaining a high index of clinical suspicion and sending specimens for mycobacterial culture are crucial to avoid missing cases. Rapid diagnostic tests reduce delays and should be performed on patients with radiological features of TB. Cite this article: Bone Joint J 2018;100-B:119-24.

The epidemiology of tuberculous dactylitis: A case report and review of literature.

The literature on tuberculous dactylitis is poor, and most literature consists of isolated case reports. The aim of this case series is to study the particularities and the epidemiological aspects of tuberculous dactylitis in Tunisian patients. Google and Medline search was done using key words "tuberculous dactylitis" and "spina ventosa." Only Tunisian reports in adult patients were included. Eleven cases including this mentioned case were included in this review. There was a female predominance, high frequency of trauma before disease installation, rarity of predisposing factors, and less inflammation in blood tests when comparing with other cases in literature.

Tuberculous Dactylitis: An Uncommon Presentation of Skeletal Tuberculosis.

BACKGROUND: Skeletal involvement accounts 1-5% of all cases of Tuberculosis. The vertebrae are more commonly affected. The bones of the hands are more affected than the bones of the feet. The term "spina ventosa" has been used to describe this disorder because of its radiographic features of cystic expansion of the involved short tubular bones. Tuberculous dactylitis mainly occurs through lympho-hematogenous spread. The lung is the primary focus in 75% of cases. CASE DETAILS: A 4 years old female child developed a painless swelling on her left index finger two months prior to her presentation. Following an unsuccessful treatment as a case of osteomyelitis with antibiotics, imaging showed an expansile lytic lesion with sclerosis, and fine needle aspiration confirmed tuberculous dactylitis. The child was initiated on anti-tubercular treatment with subsequent marked clinical and radiologic improvement. CONCLUSION: Presence of longstanding finger swelling and pain should alert a clinician to consider active disseminated tuberculosis. Furthermore, proper interpretation of imaging and use of fine needle aspiration has been highlighted.

3D-printed hierarchical scaffold for localized isoniazid/rifampin drug delivery and osteoarticular tuberculosis therapy.

After surgical treatment of osteoarticular tuberculosis (TB), it is necessary to fill the surgical defect with an implant, which combines the merits of osseous regeneration and local multi-drug therapy so as to avoid drug resistance and side effects. In this study, a 3D-printed macro/meso-porous composite scaffold is fabricated. High dosages of isoniazid (INH)/rifampin (RFP) anti-TB drugs are loaded into chemically modified mesoporous bioactive ceramics in advance, which are then bound with poly (3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) through a 3D printing procedure. The composite scaffolds show greatly prolonged drug release time compared to commercial calcium phosphate scaffolds either in vitro or in vivo. In addition, the drug concentrations on the periphery tissues of defect are maintained above INH/RFP minimal inhibitory concentrations even up to 12 weeks post-surgery, while they are extremely low in blood. Examinations of certain serum enzymes suggest no harm to hepatic or renal functions. Micro-CT evaluations and histology results also indicate partly degradation of the composite scaffolds and new bone growth in the cavity. These results suggest promising applications of our hierarchical composite scaffold in bone regeneration and local anti-TB therapy after osteoarticular TB debridement surgery.

Could high-concentration rifampicin kill rifampicin-resistant M. tuberculosis? Rifampicin MIC test in rifampicin-resistant isolates from patients with osteoarticular tuberculosis.

PURPOSE: Several studies have shown that the intralesional concentration of rifampicin in osteoarticular tuberculosis is typically at a subtherapeutic level. Sustained or controlled release by novel drug delivery systems has been investigated to maintain an effective rifampicin concentration, but the local administration of rifampicin remains controversial. Additionally, it is still unclear whether high-dose rifampicin could kill rifampicin-resistant Mycobacterium tuberculosis. The aim of this study was to assess the in vitro killing effect of high-concentration rifampicin on rifampicin-resistant M. tuberculosis isolated from patients with osteoarticular tuberculosis. METHODS: A set of 18 rifampicin-resistant M. tuberculosis isolates by the BACT/MGIT 960 system from patients with osteoarticular tuberculosis was collected for further study. The detection of rpoB gene mutations was performed using non-fluorescent, low-density DNA microarrays to determine the resistant mechanism. Following secondary culture, susceptibility to gradient concentrations of rifampicin (2 to 256 µg/ml) was tested; these concentrations are attainable for prolonged periods of local chemotherapy. The relationship between microbial killing by high-dose rifampicin and rpoB gene mutations was analyzed. RESULTS: Mutations in the rifampicin resistance-determining region (RRDR) of the rpoB gene were identified in 17 isolates (94.4%); one strain exhibited no mutations in this region. The most prevalent mutation sites were in codons 531 (55.56%), 516 (16.67%), 526 (11.11%), and 513 (11.11%). Isolates with mutations in the rpoB gene were highly resistant to rifampicin, 11 of which had minimal inhibitory concentrations (MICs) exceeding 256 µg/ml (not determined). The MICs for the remaining seven resistant isolates were between 32 and 256 µg/ml. Particularly in less rifampicin-resistant M. tuberculosis strains, growth was inhibited at high concentrations. CONCLUSION: Increasing the rifampicin concentration may optimize this drug's antituberculous effect, even against some rifampicin-resistant isolates, if systemic and local toxic effects can be minimized.

Prosthetic knee infection in the young immigrant patient--do not forget tuberculosis!

Skeletal tuberculosis (TB) frequently masquerades as more common etiologies and can be difficult to diagnose. We describe a case of TB knee arthritis in a young Haitian-born woman in whom the diagnosis was not initially suspected, resulting in treatment with total knee arthroplasty that subsequently failed. A long course of medical and surgical therapies was then necessary to treat this patient. Issues in the diagnosis and management of TB in the native and prosthetic knee joint are presented.

Evaluation of adequacy of short-course chemotherapy for extraspinal osteoarticular tuberculosis using 99mTc ciprofloxacin scan.

In the evidence-based medicine era, objective treatment guidelines have been laid down for pulmonary tuberculosis, but the same is not true for osteoarticular tuberculosis. This has led to demands for standardising the treatment protocol and to a lack of consensus between doctors regarding the composition and duration of treatment. Twenty-five patients with extraspinal osteoarticular tuberculosis were evaluated prospectively. Following the diagnosis, patients were given standard directly observed treatment short course (DOTS) regimen and were monitored for disease activity at zero, three and six months with the help of technetium-99m-labelled ciprofloxacin ((99m)Tc) scan. Tracer activity at the site was recorded and compared on sequential scans. Clinical and radiological profile of all the patients were also recorded at regular intervals and compared. All 25 cases had a positive (99m)Tc bone scan initially. Four patients (16%) converted to negative scans at three months, whereas the remaining 21 patients (84%) showed negative scans at six months. The end of six months therapy also coincided with resolution of clinical and radiological parameters in all cases. In conclusion, (99m)Tc scan is a promising tool for monitoring drug response in osteoarticular tuberculosis; however, due to the small sample size, studies with a large number of patients might be of help.

Spina ventosa discharging tubercle bacilli--a case report.

Tubercular dactylitis is an unusual form of skeletal tuberculosis. Radiographic features of cystic expansion of the short tubular bones have led to the name of "Spina Ventosa" for tuberculosis dactylitis of the short bones. We report here a case of a Spina Ventosa in a 15 year-old female, who presented with complaint of draining sinus on the dorsum of the third digit of the left foot.

Cystic bone tuberculosis in children--a case series.

Cystic tuberculosis of the bone is a rare form of tuberculosis (TB) osteomyelitis associated with disseminated lesions. In children, the lesions involve the peripheral skeleton, are symmetric and less sclerotic while in adults, the lesions are axial and predominantly sclerotic. TB dactylitis and spina ventosa are the other common variants of TB osteomyelitis seen in children below five years. Here we report seven cases of cystic TB bone disease. There were three males and four females with age of diagnosis between 2-11 years. Most patients presented with localized swelling and pain. X-rays revealed classical cystic lesions and spina ventosa. Four children had multiple cystic lesions and three had isolated lesions. Diagnosis was confirmed by FNAC of the bone or histopathological/radiological evidence of TB. The patients responded well to anti-tubercular therapy. The entity of cystic TB bone disease should be borne in mind as, lack of awareness may delay diagnosis and treatment. Biopsy is mandatory to confirm diagnosis and antitubercular drugs are the mainstay of therapy. Curettage of affected bone in selected cases may promote early healing. Response to therapy is excellent and the overall prognosis is good.

Recommendations for the diagnosis and treatment of latent and active tuberculosis in inflammatory joint diseases candidates for therapy with tumor necrosis factor alpha inhibitors: March 2008 update.

The Portuguese Society of Rheumatology and the Portuguese Society of Pulmonology have updated the guidelines for the diagnosis and treatment of latent tuberculosis infection (LTBI) and active tuberculosis (ATB) in patients with inflammatory joint diseases (IJD) that are candidates to therapy with tumour necrosis factor alpha (TNFalpha) antagonists. In order to reduce the risk of tuberculosis (TB) reactivation and the incidence of new infections, TB screening is recommended to be done as soon as possible, ideally at the moment of IJD diagnosis, and patient assessment repeated before starting anti-TNFalpha therapy. Treatment for ATB and LTBI must be done under the care of a TB specialist. When TB treatment is indicated, it should be completed prior to starting anti-TNFalpha therapy. If the IJD activity justifies the need for immediate treatment, anti-TNFalpha therapy can be started two months after antituberculous therapy has been initiated, in the case of ATB, and one month after in the case of LTBI. Chest X-ray is mandatory for all patients. If Gohn s complex is present, the patient should be treated for LTBI; healed lesions require the exclusion of ATB. In cases of suspected active lesions ATB should be excluded/confirmed and adequate therapy initiated. Tuberculin skin test, with two units of RT23, should be performed in all patients. If the induration is <5 mm, the test should be repeated within 1 to 2 weeks, on the opposite forearm, and will be considered negative only if the result is again <5 mm. Positive TST implicates LTBI treatment, unless previous proper treatment was provided. If TST is performed in immunossuppressed IJD patients, LTBI treatment should be offered to the patient before starting anti-TNFalpha therapy, even in the presence of a negative test, after risk/benefit assessment.

Tuberculosis of the metacarpals and phalanges of the hand.

Skeletal tuberculosis (TB) is less common than the pulmonary form. Involvements of the metacarpals and phalanges of the hand are infrequent. The authors report their experience with treatment and outcome of TB of the metacarpals and phalanges of the hand in 7 patients. There were 4 women and 3 men in the study who ranged in age from 3 to 60 years (average age, 22.7 years). The duration of complaints at presentation ranged from 4 to 17 months (average, 9 months). The most common presentation was pain and swelling. The presumptive preoperative diagnoses were bone tumor in 4 patients, spina ventosa in 2, and chronic pyogenic osteomyelitis in 1 patients. The results of the laboratory examination showed a mild increase in the erythrocyte sedimentation rate. No patient had an active tubercular lesion or history of pulmonary disease. The diagnosis was based on the clinical picture and radiographic features, and was confirmed by open biopsy. No patient had bony debridement or arthrodesis to control the infection. The treatment of all patients began with a 4-drug regimen for 2 months, followed by a 2-drug regimen for 10 months. The mean follow-up was 30.28 months (range, 16-52 months). At the time of the last follow-up, all lesions had healed with no recurrence. The functional results were satisfactory in all patients. One patient with thumb metacarpophalangeal TB had joint irregularity and thumb metacarpal shortening. Arthrodesis was not needed in any patient. TB of the metacarpals and phalanges of the hand can be difficult to diagnose during the early stages. TB should be suspected in cases of long-standing pain and swelling in the metacarpals and phalanges. It is necessary to keep TB in mind when making the differential diagnosis of several osseous pathologies.
