The aims of this study were to determine the diagnostic yield of image-guided biopsy in providing a final diagnosis in patients with suspected infectious spondylodiscitis, to report the diagnostic accuracy of various microbiological tests and histological examinations in these patients, and to report the epidemiology of infectious spondylodiscitis from a country where tuberculosis (TB) is endemic, including the incidence of drug-resistant TB. A total of 284 patients with clinically and radiologically suspected infectious spondylodiscitis were prospectively recruited into the study. Image-guided biopsy of the vertebral lesion was performed and specimens were sent for various microbiological tests and histological examinations. The final diagnosis was determined using a composite reference standard based on clinical, radiological, serological, microbiological, and histological findings. The overall diagnostic yield of the biopsy, and that for each test, was calculated in light of the final diagnosis.Aims

Introduction. Ascertaining the etiology of hip pain in young patients can be challenging.
The number of patients undergoing arthroscopic surgery of the
hip has increased significantly during the past decade. It has now
become an established technique for the treatment of many intra-
and extra-articular conditions affecting the hip. However, it has
a steep learning curve and is not without the risk of complications.
The purpose of this systematic review was to determine the prevalence
of complications during and following this procedure. Preferred Reporting Items for Systematic Reviews and Meta-Analyses
guidelines were used in designing this study. Two reviewers systematically
searched the literature for complications related to arthroscopy
of the hip. The research question and eligibility criteria were

The widespread use of MRI has revolutionised
the diagnostic process for spinal disorders. A typical protocol
for spinal MRI includes T1 and T2 weighted sequences in both axial
and sagittal planes. While such an imaging protocol is appropriate
to detect pathological processes in the vast majority of patients,
a number of additional sequences and advanced techniques are emerging.
The purpose of the article is to discuss both established techniques
that are gaining popularity in the field of spinal imaging and to
introduce some of the more novel ‘advanced’ MRI sequences with examples
to highlight their potential uses. Cite this article:
Atypical cartilaginous tumours are usually treated
by curettage. The purpose of this study was to show that radiofrequency
ablation was an effective alternative treatment. We enrolled 20 patients (two male, 18 female, mean age 56 years
(36 to 72) in a proof-of-principle study. After inclusion, biopsy
and radiofrequency ablation were performed, followed three months
later by curettage and adjuvant phenolisation. The primary endpoint
was the proportional necrosis in the retrieved material. Secondary endpoints
were correlation with the findings on gadolinium enhanced MRI, functional
outcome and complications. Our results show that 95% to 100% necrosis was obtained in 14
of the 20 patients. MRI had a 91% sensitivity and 67% specificity
for detecting residual tumour after curettage. The mean functional
outcome (MSTS) score six weeks after radiofrequency ablation was
27.1 (23 to 30) compared with 18.1 (12 to 25) after curettage (p
<
0.001). No complications occurred after ablation, while two
patients developed a pathological fracture after curettage. We have shown that radiofrequency ablation is capable of completely
eradicating cartilaginous tumour cells in selective cases. MRI has
a 91% sensitivity for detecting any residual tumour. Radiofrequency
ablation can be performed on an outpatient basis allowing a rapid
return to normal activities. If it can be made more effective, it
has the potential to provide better local control, while improving
functional outcome. Cite this article:
Introduction. The femoral neck in children is a common site for bone lesions. The majority are benign. However these lesions can cause diagnostic problems. Aim. To present a spectrum of chronic lesions of the femoral neck in children and emphasize the importance of tissue diagnosis. Materials and methods. Thirty two children with isolated chronic bone lesions in the femoral neck treated between 1994 and 2013were retrospectively reviewed. The ages ranged between 1–13 years. Clinical features were pain and limp. Routine blood tests, x-rays and CT scans were done in all and MRI scans in 5 cases. All diagnoses were confirmed histologically. Results. Three radiological patterns were seen: lucent or cystic in 22, infiltrative (permeative)in 2, and localized densities with nidus in 8 cases. Histologically the lesions were subacute osteomyelitis in 4, tuberculosis in 9, simple bone cyst in 7,
Purpose of the study. To review the primary bone tumours of the spine treated at our unit. Description of methods. Retrospective review of folders and x-rays of all the patients with primary bone tumours of the spine treated at our unit between 2005 and 2012. All haematological tumours were excluded. Summary of results. We treated 15 cases during this period. The median age at presentation was 36 years (8–65). There was a significant delay from onset of symptoms to diagnosis in most cases (median 7 months). Histological diagnoses included:. -Benign tumours. Active. Hemangioma. 3.
Introduction. Hand tumors are usually rare and there is not much literature about series of cases. We have studied a series of 110 cases. Hand tumors do consists of both benign and malignant cases. Methods. We studied series of 110 cases at Karnataka Institute of Medical Sciences, Hubli and Mysore Medical College & Research Institute, Mysore. We retrospectively reviewed the records of 110 patients who underwent double ray amputations at our center over few years: few had amputations of the fourth and fifth rays and others amputation of the second and third rays. Mean age at surgery was 34 years (range, 10–45 years), and minimum follow up was 64 months (mean, 98 months; range, 64–136 months). Some patients had high-grade soft tissue sarcomas of the hand, synovial sarcomas, malignant peripheral nerve sheath tumors, and undifferentiated sarcoma. No patients had detectable metastases at surgery. Results. All patients were completely disease-free at latest follow up. One patient was alive with lung metastases detected 32 months after surgery. No patients developed local tumor recurrence. Functional assessment showed a mean Musculoskeletal Tumor Society score of 24 (range, 19–28) and mean grip strength 24% of the contra lateral side (range, 17%–35%). Conclusions. The majority of osseous tumors of the hand are benign. The surgeon who evaluates and treats osseous tumors of the hand has to be familiar with limb anatomy, tumor biology, various presentations of the tumors and the range of treatment possibilities and their limitations. Lesions in the hand more often present earlier in their course than those at other sites, just because they are more likely to superficial and easily noticed. Ganglion cyst is the most frequently encountered comprising 50–70% of benign tumors of hand. Enchondroma was the next common benign bone tumour followed by
Back pain is a common symptom in children and
adolescents. Here we review the important causes, of which defects
and stress reactions of the pars interarticularis are the most common
identifiable problems. More serious pathology, including malignancy
and infection, needs to be excluded when there is associated systemic
illness. Clinical evaluation and management may be difficult and
always requires a thorough history and physical examination. Diagnostic
imaging is obtained when symptoms are persistent or severe. Imaging
is used to reassure the patient, relatives and carers, and to guide
management. Cite this article:
Purpose. The hip region is the second most common site for tuberculosis following the spine in children. The aim is to describe the variable radiological patterns of presentation and their resemblance to pyogenic infection, tumours and other benign conditions of bone in children. Methods. The clinical and radiological records of 29 children aged 10 months–13 years with confirmed tuberculosis of the hip region seen between 1990 and 2011 were reviewed retrospectively. Clinical features were pain, limp and flexion, adduction contractures. Abscesses and sinuses were seen in 4 children. The ESR ranged between 7–110 mm/hr. Mantoux was positive in 20 children. All cases were histologically confirmed. Treatment involved biopsy, currettage of bone defects, limited synovectomy and adductor tenotomy. Patients were immobilised for 4 weeks on a spica cast or traction. Antituberculous treatment was administered for 9–12 months. Results. Radiologically 9 lesions were extra-articular and 20 involved the joint synovium and articular surface. Extra-articular lesions were seen in the pubis, greater and lesser trochanter, ilium, proximal femur and peri-acetabular regions. Intra-articular lesions were seen in the femoral head, neck and acetabulum. Dislocations and subluxations occurred in 8 patients; various lesions mimicked pyogenic arthritis, idiopathic chondrolysis, chondrobastoma, Perthes disease, eosinophilic granuloma and

Pathological fractures in children can occur
as a result of a variety of conditions, ranging from metabolic diseases and
infection to tumours. Fractures through benign and malignant bone
tumours should be recognised and managed appropriately by the treating
orthopaedic surgeon. The most common benign bone tumours that cause pathological
fractures in children are unicameral bone cysts, aneurysmal bone
cysts, non-ossifying fibromas and fibrous dysplasia. Although pathological
fractures through a primary bone malignancy are rare, these should
be recognised quickly in order to achieve better outcomes. A thorough
history, physical examination and review of plain radiographs are
crucial to determine the cause and guide treatment. In most benign
cases the fracture will heal and the lesion can be addressed at
the time of the fracture, or after the fracture is healed. A step-wise
and multidisciplinary approach is necessary in caring for paediatric
patients with malignancies. Pathological fractures do not have to
be treated by amputation; these fractures can heal and limb salvage
can be performed when indicated.

Introduction. Chondroblastomas are rare bone tumours accounting for approximately 1% of all benign bone lesions. They occur in children and adolescents and are more frequent in males. The conventional treatment for chondroblastomas is surgery, however, this can be difficult and disabling due to the apo- or epiphyseal location. Surgery is curative in most cases, but recurrence rates of 10%–35% have been reported in the literature. Radiofrequency ablation is well established in the treatment of
