Abstract:
Osteoarticular tuberculosis is a rare type of tuberculosis. The spine is the most frequent location, while peripheral locations in the limbs are rare. We report a case of tuberculous osteoarthritis of the metatarsophalangeal joint of the first ray of the foot in a 48-year-old woman. The patient presented with painful swelling of the dorsum of the big toe, insidiously evolving for 6months. Diagnosis was obtained with histological study after surgical biopsy. Antitubercular chemotherapy for 12months promoted healing. Through this clinical case the authors describe the epidemiological, diagnostic features, and treatment of osteoarticular tuberculosis and discuss the causes of delayed diagnosis often encountered in these exceptional locations and differential diagnoses, gout in particular, for this particular case.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
