Intra-articular osteoid osteoma in the femoral neck of an 18-year-old man: a case report.

Objective: This case study presents the delayed diagnosis, surgical management, and postsurgical follow-up of an intra-articular osteoid osteoma of the left femoral neck in an 18-year-old male patient with special emphasis on discussing the confusing clinical and imaging characteristics of the lesion often associated with delayed diagnosis and increased morbidity.

Clinical Features: The patient initially complained of left knee and hip pain at which time conventional radiographs were reported as normal. In magnetic resonance imaging studies, the diagnosis of intra-articular osteoid osteoma of the femoral neck was suggested; however, working diagnoses also included old posttraumatic injury, hip infection, juvenile chronic arthritis, and posttraumatic arthritis.

Adherence to radiography guidelines for low back pain: a survey of chiropractic schools worldwide.

Objective: This study describes instruction provided at chiropractic schools worldwide on the use of spine radiography and compares instruction with evidence-based guidelines for low back pain.

Methods: Individuals responsible for radiology instruction at accredited chiropractic schools throughout the world were contacted and invited to participate in a Web-based survey. The survey included questions on the role of conventional radiography in chiropractic practice and instruction given to students for its use in patients with acute low back pain.

Glenoid hypoplasia: a report of 2 patients.

Objective: This article discusses the imaging findings, clinical findings, and conservative chiropractic management of 2 patients with glenoid hypoplasia.

Clinical Features: Conventional radiographs of both patients revealed a hypoplastic glenoid bilaterally. Notch-like defects along with signs of degenerative disease were evident within the lower portion of the glenoid rims bilaterally in 1 patient and in the left glenoid rim of the other patient.

Diagnostic imaging practice guidelines for musculoskeletal complaints in adults-an evidence-based approach-part 3: spinal disorders.

Purpose: To develop evidence-based diagnostic imaging practice guidelines to assist chiropractors and other primary care providers in decision making for the appropriate use of diagnostic imaging for spinal disorders.

Methods: A comprehensive search of the English and French language literature was conducted using a combination of subject headings and keywords. The quality of the citations was assessed using the Quality of diagnostic accuracy studies (QUADAS), the Appraisal of Guidelines Research and Evaluation (AGREE), and the Stroke Prevention and Educational Awareness Diffusion (SPREAD) evaluation tools.

Diagnostic imaging guideline for musculoskeletal complaints in adults-an evidence-based approach-part 2: upper extremity disorders.

Purpose: To develop evidence-based diagnostic imaging practice guidelines to assist chiropractors and other primary care providers in decision making for the appropriate use of diagnostic imaging for upper extremity disorders.

Methods: A comprehensive search of the English and French language literature was conducted using a combination of subject headings and keywords. The quality of the citations was assessed using the Quality of diagnostic accuracy studies (QUADAS), the Appraisal of Guidelines Research and Evaluation (AGREE), and the Stroke Prevention and Educational Awareness Diffusion (SPREAD) evaluation tools.

Diagnostic imaging practice guidelines for musculoskeletal complaints in adults--an evidence-based approach. Part 1. Lower extremity disorders.

Purpose: The aim of this study was to develop evidence-based diagnostic imaging practice guidelines to assist chiropractors and other primary care providers in decision making for the appropriate use of diagnostic imaging of lower extremity disorders.

Methods: A comprehensive search of the English and French language literature was conducted using a combination of subject headings and keywords. The quality of the citations was assessed using the Quality of Diagnostic Accuracy Studies (QUADAS), the Appraisal of Guidelines Research and Evaluation (AGREE), and the Stroke Prevention and Educational Awareness Diffusion (SPREAD) evaluation tools.

Diagnostic imaging practice guidelines for musculoskeletal complaints in adults--an evidence-based approach: introduction.

Purpose: Imaging technology can improve patient outcomes by allowing greater precision in diagnosing and treating patients. However, there is evidence that overuse, underuse, and misuse of imaging services occur. The purpose of this project was to develop evidence-based diagnostic imaging practice guidelines for musculoskeletal complaints for use by doctors of chiropractic and other primary health care professionals.

A case of vertebral metastasis with pathologic c2 fracture.

Objective: This report discusses a patient with a pathologic fracture of the C2 vertebra secondary to osteolytic metastasis from squamous cell carcinoma of the lung.

Clinical Features: The patient was a 68-year-old man with a chief complaint of neck pain who was referred by his physician to a chiropractic office. The initial onset of neck pain began after a forceful sneeze that resulted in a sensation of "a twig snapping" in the neck.

Merkel cell carcinoma arising from the subcutaneous fat of the arm with intact skin.

Background: Merkel cell carcinoma is a rare malignant neuroendocrine neoplasm characteristically arising from the dermis of sunlight-exposed skin. It rarely arises outside the skin.

Objective: We present a patient with primary Merkel cell carcinoma arising from subcutaneous fat, with no involvement of the overlying skin.

Xanthoma of the sacrum.

Xanthoma is a lesion containing abundant foamy histiocytes most commonly occurring in superficial soft tissues such as skin, subcutis, or tendon sheaths. The involvement of deep skeletal structures, however, is rare and has only been infrequently reported in the English literature. Most xanthomas occur in patients with hyperlipidemic disorders.

Eosinophilic fasciitis in a military recruit: MRI evaluation with clinical correlation.

Eosinophilic fasciitis (EF) is an uncommon connective tissue disease. We report a patient with EF who presented with episodic swelling and stiffness of his legs and forearms in combination with peripheral eosinophilia. Imaging studies of the legs and forearms, including computed tomography (CT) and magnetic resonance imaging (MRI), clearly demonstrated the characteristic finding of fascial thickening.
