Role of tranexamic acid in reducing peri-operative blood loss in open spine surgeries.

Spine surgeries are associated with significant blood loss due to the extensive soft tissue dissection, bony decompression, and prolonged surgical time. Excessive bleeding may require blood transfusions and thereby increase the risk of adverse transfusion reactions. Therefore, minimizing peri-operative bleeding is important for spine surgeons to reduce post-operative morbidity. Tranexamic acid (TXA) is a synthetic anti-fibrinolytic drug, which helps in reducing perioperative blood loss in major surgeries. The evidence on the efficacy of this agent in all manner of spine surgeries is not sufficient. Hence this study was conducted to determine the efficacy of TXA on perioperative blood loss in major spinal surgeries. In a prospective study, two groups of patients with similar surgical profiles who were posted for all manner of open spine surgeries were included. One group received one gram of intravenous TXA while the others did not. Intra- and post-operative assessments included noting levels of surgery, duration of surgery, assessment of blood loss, intra- and/or post- operative blood transfusion, and blood collected in surgical drain at the end of 24 h. The intra-operative blood loss, frequency of intra-operative blood transfusion, post-operative Hemoglobin drop, and surgical drain output were found to be significantly lower in patients who received TXA. In spine surgeries, TXA was found to be effective in reducing intra-operative blood loss, need for intra-operative blood transfusion and post-operative Hb drop. Also, TXA had reduced surgical drain output significantly between the two groups.

Feature-based multimodal registration framework for vertebral pose estimation.

PURPOSE: The reliable estimation of the vertebral body posture helps to aid a safe and effective spine surgery. The proposed work aims to present an MR to X-ray image registration to assess the 3D pose of the vertebral body during spine surgery. The 3D assessment of vertebral pose assists in analyzing the position and orientation of the vertebral body to provide information during various clinical diagnosis conditions such as curvature estimation and pedicle screw insertion surgery. METHODS: The proposed feature-based registration framework extracted vertebral end plates to avoid the mismatch between the intensities of MR and X-ray images. Using the projection matrix, the segmented MRI is forward projected and then registered to the X-ray image using binary image matching similarity and the CMA-ES optimizer. RESULTS: The proposed method estimated the vertebral pose by registering the simulated X-ray onto pre-operative MRI. To evaluate the efficacy of the proposed approach, a certain number of experiments are carried out on the simulated dataset. CONCLUSION: The proposed method is a fast and accurate registration method that can provide 3D information about the vertebral body. This 3D information is useful to improve accuracy during various clinical diagnoses.

Effectiveness of Deep Cervical Fascial Manipulation® and Sequential Yoga Poses on Pain and Function in Individuals with Mechanical Neck Pain: A Randomised Controlled Trial.

BACKGROUND: This study aimed to investigate the effect of fascial manipulation (FM) of the deep cervical fascia (DCF) and sequential yoga poses (SYP) on pain and function in individuals with mechanical neck pain (MNP). METHOD: Following the predefined criteria, ninety-nine individuals with MNP were recruited, randomised, and assigned to either the intervention group (IG) (n = 51) or the control group (CG) (n = 48). Individuals in the IG received FM (4 sessions in 4 weeks) and the home-based SYP (4 weeks). The CG participants received their usual care (cervical mobilisation and thoracic manipulation (4 sessions in 4 weeks) along with unsupervised therapeutic exercises (4 weeks). The participants underwent baseline and weekly follow-up measurements of pain using a numerical pain rating scale (NPRS) and elbow extension range of motion (EEROM) during the upper limb neurodynamic test 1 (ULNT1). The baseline and the fourth session follow-up measurements of the patient-specific functional scale (PSFS) and fear-avoidance behavior Questionnaire (FABQ) were also taken. RESULTS: A repeated-measures ANOVA was performed. There were statistically significant differences between the IG and CG on the NPRS third and fourth sessions, with mean differences (MD) of -1.009 (p < 0.05) and -1.701 (p < 0.001), respectively. Regarding EEROM, there was a 20.120° difference (p < 0.001) in the fourth session between the groups. The MD in FABQ was -5.036 (p < 0.001), but there were no significant differences in PSFS between the groups during the follow-up. CONCLUSION: FM and SYP can aid in reducing pain and fear-avoidance behaviour and improve the function and extensibility of the upper quarter region.

Effect of Multifactorial Balance Rehabilitation Program on Risk of Falls and Functional Fitness in Older Adults with Diabetic Peripheral Neuropathy.

BACKGROUND: Increasing age and the added disadvantage of diabetic peripheral neuropathy (DPN) put the individual at a higher risk of falls and reduced functional fitness. However, there is a dearth of literature on multifactorial balance intervention, especially targeting the needs of older adults with DPN. OBJECTIVE: The current study aimed to determine the effect of a multifactorial balance rehabilitation program on fall risk and functional fitness in older adults with DPN. METHODS: In this pre-post experimental study, 30 independently ambulating older adults (71.2 ± 4.70 years) with DPN, who were at risk of falling (timed up and go score ≥ 9.4 seconds), were recruited. Along with the standard care, all the participants received 12 weeks of the multifactorial balance rehabilitation program. RESULTS: Fall risk using the Fullerton Advanced Balance scale and functional fitness using the Senior Fitness Test were measured at baseline and after 12 weeks of the intervention. The intervention reduced the risk of falling score significantly (MD = 6.17, p < .001). All six parameters of functional fitness improved after 12 weeks of intervention. The improvement in lower limb strength (MD = 1.53 times), upper limb strength (MD = 2.48 times), endurance (MD = 16.07 seconds), lower limb flexibility (MD = 2.02 inches), upper limb flexibility (MD = 1.47 inches), and dynamic balance (MD = 1.53 seconds) was statistically significant at p < 0.05. CONCLUSION: This study provided encouraging evidence about the potential of multifactorial balance rehabilitation to reduce the risk of falling and improve functional fitness in older adults with DPN.

Evaluating similarity measure for multimodal 3D to 2D registration.

The 3D to 2D registration technique in spine surgery is vital to aid surgeons in avoiding the wrong site surgery by estimating the vertebral pose. The vertebral poses are estimated by generating the spatial correspondence relationship between pre-operative MR with intra-operative x-ray images, then evaluated using a similarity measure. Different similarity measures are used in 3D to 2D registration techniques to assess the spatial correspondence between the pre-operative and intra-operative images. However, to evaluate the registration performance of the similarity measures, the proposed framework employs three different similarity measures: Binary Image Matching, Dice Coefficients, and Normalized Cross-correlation technique to compare the images based on pixel positions. The registration accuracy of the proposed similarity measures is compared based on the mean Target Registration Error, mean Iteration Times, and success rate. In the absence of simulated test images, the experiment is conducted on the simulated AP and Lateral test images. The experiment conducted on the simulated test images shows that all three similarity measures work well for the feature based 3D to 2D registration in that BIM gives better results. The experiment also indicates high registration accuracy when the initial displacements are varied up to ±20 mm and ±100of the translational and rotational parameters, respectively, for three similarity measures.

A Hybrid 3D-2D Image Registration Framework for Pedicle Screw Trajectory Registration between Intraoperative X-ray Image and Preoperative CT Image.

Pedicle screw insertion is considered a complex surgery among Orthopaedics surgeons. Exclusively to prevent postoperative complications associated with pedicle screw insertion, various types of image intensity registration-based navigation systems have been developed. These systems are computation-intensive, have a small capture range and have local maxima issues. On the other hand, deep learning-based techniques lack registration generalizability and have data dependency. To overcome these limitations, a patient-specific hybrid 3D-2D registration principled framework was designed to map a pedicle screw trajectory between intraoperative X-ray image and preoperative CT image. An anatomical landmark-based 3D-2D Iterative Control Point (ICP) registration was performed to register a pedicular marker pose between the X-ray images and axial preoperative CT images. The registration framework was clinically validated by generating projection images possessing an optimal match with intraoperative X-ray images at the corresponding control point registration. The effectiveness of the registered trajectory was evaluated in terms of displacement and directional errors after reprojecting its position on 2D radiographic planes. The mean Euclidean distances for the Head and Tail end of the reprojected trajectory from the actual trajectory in the AP and lateral planes were shown to be 0.6-0.8 mm and 0.5-1.6 mm, respectively. Similarly, the corresponding mean directional errors were found to be 4.90 and 20. The mean trajectory length difference between the actual and registered trajectory was shown to be 2.67 mm. The approximate time required in the intraoperative environment to axially map the marker position for a single vertebra was found to be 3 min. Utilizing the markerless registration techniques, the designed framework functions like a screw navigation tool, and assures the quality of surgery being performed by limiting the need of postoperative CT.

Realistic C-arm to pCT registration for vertebral localization in spine surgery : A hybrid 3D-2D registration framework for intraoperative vertebral pose estimation.

Spine surgeries are vulnerable to wrong-level surgeries and postoperative complications because of their complex structure. Unavailability of the 3D intraoperative imaging device, low-contrast intraoperative X-ray images, variable clinical and patient conditions, manual analyses, lack of skilled technicians, and human errors increase the chances of wrong-site or wrong-level surgeries. State of the art work refers 3D-2D image registration systems and other medical image processing techniques to address the complications associated with spine surgeries. Intensity-based 3D-2D image registration systems had been widely practiced across various clinical applications. However, these frameworks are limited to specific clinical conditions such as anatomy, dimension of image correspondence, and imaging modalities. Moreover, there are certain prerequisites for these frameworks to function in clinical application, such as dataset requirement, speed of computation, requirement of high-end system configuration, limited capture range, and multiple local maxima. A simple and effective registration framework was designed with a study objective of vertebral level identification and its pose estimation from intraoperative fluoroscopic images by combining intensity-based and iterative control point (ICP)-based 3D-2D registration. A hierarchical multi-stage registration framework was designed that comprises coarse and finer registration. The coarse registration was performed in two stages, i.e., intensity similarity-based spatial localization and source-to-detector localization based on the intervertebral distance correspondence between vertebral centroids in projected and intraoperative X-ray images. Finally, to speed up target localization in the intraoperative application, based on 3D-2D vertebral centroid correspondence, a rigid ICP-based finer registration was performed. The mean projection distance error (mPDE) measurement and visual similarity between projection image at finer registration point and intraoperative X-ray image and surgeons' feedback were held accountable for the quality assurance of the designed registration framework. The average mPDE after peak signal to noise ratio (PSNR)-based coarse registration was 20.41mm. After the coarse registration in spatial region and source to detector direction, the average mPDE reduced to 12.18mm. On finer ICP-based registration, the mean mPDE was finally reduced to 0.36 mm. The approximate mean time required for the coarse registration, finer registration, and DRR image generation at the final registration point were 10 s, 15 s, and 1.5 min, respectively. The designed registration framework can act as a supporting tool for vertebral level localization and its pose estimation in an intraoperative environment. The framework was designed with the future perspective of intraoperative target localization and its pose estimation irrespective of the target anatomy.

Effectiveness of posture-correction interventions for mechanical neck pain and posture among people with forward head posture: protocol for a systematic review.

INTRODUCTION: Forward head posture (FHP) is the most common postural deviation of the upper back. It is believed to be one of the predisposing factors for the development of mechanical neck pain (MNP). We propose doing a systematic review to find the effectiveness of interventions targeted on FHP with MNP and assess implementation fidelity associated with these interventions. METHODS AND ANALYSIS: Medline (PubMed), Web of Science (Social Science Citation Index), EMBASE, Scopus, PEDro and CINAHL databases will be searched for studies published in English from their inception. Forward and backward citations of the included studies will be investigated for identifying additional records. We will include randomised controlled trials and non/quasi-experimental studies with two groups assessing the effectiveness of interventions targeted on FHP with MNP. Observational studies, non-randomised studies with single group and reviews will be excluded. We will consider the following outcome measures: postural variables of FHP, neck pain, performance-based functional disability scores of the neck, quality of life, basic activities of daily living and work-related outcomes. The unique citations will be screened by titles/abstracts and full texts, independently. The Cochrane Risk of Bias 2 tool will be used to critically appraise the included studies. The risk of bias and data abstraction of included studies will be undertaken independently. A qualitative synthesis will be conducted and, if sufficient studies with comparable outcome measures are available, we will statistically pool the result. ETHICS AND DISSEMINATION: We will undertake a systematic review of primary studies, and will not directly recruit participants hence, ethical clearance is not applicable. We will aim to present the findings of the completed systematic review at an international conference and subsequently submit the manuscript in a peer-reviewed journal for publication.

Fear of Falling and Functional Mobility in Elders with Diabetic Peripheral Neuropathy in Coastal Karnataka, India: A Hospital-Based Study.

BACKGROUND: Aging with diabetic neuropathy is likely to predispose people to falls. Despite being a high-risk population, estimates of falls and their associated factors are poorly documented in elderly diabetic neuropathy patients living in coastal Karnataka, India. OBJECTIVE: To investigate fear of falling and functional mobility, as an approximate measure of clinical fall risk, and explore the associated risk factors in elderly diabetic neuropathy patients living in coastal Karnataka, India. METHODS: A hospital-based cross-sectional study was conducted on 316 elders aged 60 to 80 with diabetic neuropathy. A detailed diabetic foot evaluation was done. Self-reported fear of fall and functional mobility was measured using the Falls Efficacy Scale- International and Timed Up and Go test, respectively, with published cut-points. Additionally, a recall of 12 months of fall history was recorded. RESULTS: Descriptive analysis showed that self-reported fear of fall and below-average functional mobility was present in 39% and 49% of the elders with diabetic neuropathy, respectively. Spearman's correlational analysis revealed that self-reported fall concerns and functional mobility are significantly interdependent. Regression analysis suggested female gender, the severity of neuropathy, and previous falls as significant modifiers for fear of falls and poor functional mobility. CONCLUSION: Half of the elders (49%) with diabetic neuropathy have poor functional mobility and 39% have a fear of falling. Improving physical function and addressing fall concerns of elders with diabetic neuropathy can result in greater confidence to participate in everyday activities and contribute to their better health. Hence, early fall risk identification is recommended for providing better health care to these individuals.

Clinical profile, diagnosis, treatment, and outcome of patients with tubercular versus nontubercular causes of spine involvement: A retrospective cohort study from India.

Background: In tuberculosis (TB) endemic areas, other pyogenic causes of spine involvement may be missed. The study aimed to describe TB and non-TB causes of spine involvement and identify features that can help in differentiating them. Methods: A retrospective cohort study was conducted to screen the clinical records of all admitted patients (Kasturba Hospital, Manipal) in 2018-20 for a diagnosis of spondylitis and/or sacroiliitis. The clinical features, radiological findings, laboratory parameters, treatment details, and outcomes were compared among those diagnosed with confirmed TB, confirmed brucellosis, or confirmed pyogenic infection. A scoring system was also developed to differentiate spondylodiscitis due to tuberculous and pyogenic causes. The qualitative variables were compared using the Chi-square test, while quantitative variables were compared using the one-way analysis of variance test. Results: Of 120 patients with spine infections, a total of 85 patients were confirmed with the microbiological diagnosis of interest. Involvement of the thoracic spine, longer duration of illness, and caseous granulomatous reaction on histopathology was more common in TB patients. Male gender, involvement of lumbar vertebra, and neutrophilic infiltrate on histopathology were more common in brucellosis patients. Male gender, diabetes mellitus, involvement of lumbar vertebra, neutrophilic infiltrate on histopathology, leukocytosis, and increased C-reactive protein were more commonly seen in patients with pyogenic infection. The scoring system had a sensitivity and specificity of 75% and 91%, respectively, when used to differentiate TB from pyogenic infection. Conclusions: In resource-limited settings, suggestive findings can be used to decide empiric therapy.

Differentiating tubercular from pyogenic causes of spine involvement on Magnetic Resonance Imaging.

Introduction: Based on clinical parameters alone, it is difficult to differentiate between tubercular (TB) and pyogenic spondylodiscitis. Therefore, this study aimed to identify imaging features that can help to differentiate these two entities. Methodology: This retrospective observational study included microbiologically confirmed cases of TB and pyogenic spondylitis over three years. Magnetic resonance imaging of included cases was reviewed for a predefined set of imaging findings. A multivariable logistic regression analysis was done to compare the radiological features of both groups. A scoring system was created using the features that were significant in univariate and multivariable analysis. Results: Of the 90 included cases, 44 were TB and 46 were pyogenic. Involvement of the thoracic vertebra, paravertebral abscess, epidural abscess, posterior element involvement, loss of height, spine deformity, nerve compression, destruction of the disc and larger abscess size were more common in patients with TB. Involvement of the thoracic spine, posterior element involvement and spine deformity were independent predictors of diagnosing TB spine. At a score of 7 (out of 11) or above, the scoring system had a sensitivity and specificity of 86% and 94%, respectively, in diagnosing the TB spine. Conclusion: In the presence of relevant clinical findings, specific MRI findings can help to differentiate TB from pyogenic spondylitis.

Brown tumour mimicking skeletal metastasis.

Brown tumours of bone are highly vascular osteolytic lesions that depict a reparative cellular process instead of a neoplastic process in hyperparathyroidism (HPT) patients. These tumours have the potential to be aggressive and destructive. We report a case of a 30-year-old woman who presented with left thigh and lower back pain. The radiological evaluation showed multiple bony lesions in the pelvis and the spine, which mimicked multiple metastatic tumours. However, on biochemistry evaluation, serum calcium, alkaline phosphatase, and parathyroid hormone were all high, while serum phosphate was low, indicating primary HPT (PHPT), which was confirmed by parathyroid scintigraphy showing left parathyroid adenoma. Hence, the bony lesions were diagnosed as brown tumours secondary to PHPT. The patient underwent parathyroidectomy and developed severe hungry bone syndrome requiring parenteral calcium infusion along with oral calcium and active vitamin D supplementation. The clinical symptoms of bone pain improved after surgery.

Cryptococcal spondylodiscitis in a non-HIV patient with CD4 lymphocytopenia.

Infections that affect the intervertebral discs and vertebrae are known as spondylodiscitis. Such infections are commonly caused by pyogenic organisms, particularly Staphylococcus aureus, and hematogenous spread is the most common route. Non-pyogenic infections include Mycobacterium tuberculosis and Brucellosis. Mycotic infections are becoming more common, in line with the growing number of immunodeficiency disorders. Cryptococcus is included among these mycotic infections. We present a case of such an infection in a non-immunocompromised patient with a known history of treatment with antitubercular therapy. A 52-year-old man came to our hospital with a backache of one-month duration and progressive neurological deficits of the lower limbs of one-week duration. His imaging studies were suggestive of spondylodiscitis at the D10-11 and D11-12 levels with a left paraspinal abscess. The patient underwent anterolateral decompression, biopsy, and instrumented posterior spinal fusion. The pus grew Cryptococcus, and histopathology confirmed Cryptococcal spondylodiscitis. The patient was treated with parenteral amphotericin B and fluconazole. A mycotic infection must be considered in the differential diagnosis of infectious spondylodiscitis.

Outcome analysis of antibiotic-loaded poly methyl methacrylate (PMMA) beads in musculoskeletal infections.

OBJECTIVE: Despite the availability of an extensive array of antibiotics, musculoskeletal infections are not cured successfully. It is necessary to remove sequestra, infected necrotic tissue, and implants. This study was undertaken to assess the efficacy of poly methyl methacrylate (PMMA) beads and identify the variables that influence eradication and recurrence in the treatment of musculoskeletal infections. METHODS: This study was conducted on 82 patients with chronic osteomyelitis who were treated over a period of 6 years at our tertiary care hospital. We followed up with 71 patients for one year. Clinicoradiological data for the control of infection and bone healing were assessed at the final follow up visit. The correlation between antibiotic sensitivity/resistance and infection was evaluated for Gentamicin + Cefuroxime and Gentamicin + Vancomycin combinations. Chi-squared testing, using SPSS version 16.0, was used for statistical analysis, and a p-value < 0.05 was considered significant. RESULTS: Fifty-three patients (65.4%) had an exogenous route of infection. Fifty-six patients (68.51%) presented with a discharging sinus on first presentation. In 42 patients (59%), the diagnosis was verified with a positive bacterial culture. In addition, we used antibiotic beads of Gentamicin + Cefuroxime in 74 patients (90%), while in 8 patients (10%), we used Gentamicin + Vancomycin, based on culture and sensitivity results. Recurrence was found in five cases of Gentamicin + Cefuroxime and two cases of Gentamicin + Vancomycin (p = 0.065). CONCLUSION: Antibiotics containing PMMA beads are effective in the treatment of chronic osteomyelitis and in preventing the recurrence of infection. It is imperative to identify various factors responsible for the recurrence of infection. This may help clinicians predict the prognosis of the disease and minimise the risk of adverse outcomes.

Infiltrating spinal angiolipoma with paraplegia and hydrocephalus: A rare case report.

Angiolipoma is a rare subtype of lipoma that contains both mature adipocytes and a rich vascular component. Infiltrating spinal angiolipomas causes surgical challenges with potential on-table injuries to adjacent structures. We present a rare case of infiltrating spinal angiolipoma in a 76-year-old woman who presented with paraplegia and hydrocephalus. At the time of presentation, the patient was bedridden for 3 months due to a complete loss of motor power. Imaging examination revealed a lesion involving the T6 vertebra with compressive myelopathy. The patient underwent spinal decompression and resection of the lesion, which turned out to be an infiltrating angiolipoma by histological examination. This is a unique case because spinal angiolipoma is extremely uncommon and such lesions generally manifest without infiltration. This case report highlights the existence and importance of spinal angiolipoma as a differential diagnosis of chronic backache resulting in neurological deficits and hydrocephalus.

Computerized image understanding system for reliable estimation of spinal curvature in idiopathic scoliosis.

Analysis of scoliosis requires thorough radiographic evaluation by spinal curvature estimation to completely assess the spinal deformity. Spinal curvature estimation gives orthopaedic surgeons an idea of severity of spinal deformity for therapeutic purposes. Manual intervention has always been an issue to ensure accuracy and repeatability. Computer assisted systems are semi-automatic and is still influenced by surgeon's expertise. Spinal curvature estimation completely relies on accurate identification of required end vertebrae like superior end-vertebra, inferior end-vertebra and apical vertebra. In the present work, automatic extraction of spinal information central sacral line and medial axis by computerized image understanding system has been proposed. The inter-observer variability in the anatomical landmark identification is quantified using Kappa statistic. The resultant Kappa value computed between proposed algorithm and observer lies in the range 0.7 and 0.9, which shows good accuracy. Identification of the required end vertebra is automated by the extracted spinal information. Difference in inter and intra-observer variability for the state of the art computer assisted and proposed system are quantified in terms of mean absolute difference for the various types (Type-I, Type-II, Type-III, Type-IV, and Type-V) of scoliosis.

Tension pneumocephalus following an implant removal from spine.

Pneumocephalus is commonly seen after skull and maxillofacial fractures. It can also occur following cerebrospinal fluid leak after skull base surgery and epidural catheter placement. We report a rare case report of a 20-year-old man who developed tension pneumocephalus following implant removal from the spine. He responded well to the conservative treatment without any neurological complications.

Spondylodiscitis due to Salmonella Typhi: a series of four cases.

Salmonella Typhi is very rarely associated with focal bone and joint complications. Classically, they are described in patients with risk factors such as haemoglobinopathies. We report four cases of spondylodiscitis, where the aetiology was found to be Salmonella Typhi. All four cases were treated successfully with variable duration of ceftriaxone followed by cotrimoxazole. We report these cases to highlight the importance of obtaining a microbiological diagnosis and the possibility of a rare infection in endemic settings.

Osteoarticular melioidosis: a retrospective cohort study of a neglected disease.

INTRODUCTION: Patients with melioidosis can present with a combination of fever, respiratory distress and focal involvement. Focal involvement of bone and joint is, however, rare in patients with melioidosis. This study aimed to characterize patients with osteoarticular melioidosis. PATIENTS AND METHODS: This was a retrospective review of records of all adult patients diagnosed with culture-positive osteoarticular melioidosis over three years. The clinical, laboratory and treatment details were recorded in a predefined case-record form and analyzed. RESULTS: Of the 11 patients with osteoarticular melioidosis, 55% (n=6) had concurrent pulmonary involvement. The patients were classified as isolated osteomyelitis (n=3), isolated arthritis (n=3), and both osteomyelitis and septic arthritis (n=5). Of eight patients with joint involvement, 87.5% had monoarthritis. A single bone was involved in 75% of the patients with bone involvement (n=8). Concomitant myositis was seen in 36.4% (n=4) of the cases. Local debridement of the involved bone or joint was done in 54.5% (n=6) of the cases. Combination therapy with ceftazidime/meropenem and cotrimoxazole was predominantly used as intensive therapy for a mean of 3+1.3 weeks. Monotherapy with cotrimoxazole was used as eradication therapy for a mean of 4.6+2 months. Except for one patient with recurrent disease and one death, all patients were declared cured at the end of therapy. CONCLUSION: Osteoarticular melioidosis should be suspected in high-risk individuals from endemic areas with single bone or joint involvement and surrounding myositis. Early diagnosis and prompt initiation of therapy is key to a favourable response.
