Joint inflammation caused by typhoid fever bacteria spreading to the joints.
Because typhoid arthritis is rated based on the affected joint's actual findings, the most useful evidence is whatever documents how that joint functions. Medical records showing range-of-motion measurements, imaging results, and any surgical records for joint replacement or resurfacing are directly relevant. If a joint has been replaced, operative reports, discharge summaries, and dates of hospital discharge help establish when the post-surgical rating periods begin. For ankylosis of the fingers, thumb, or other joints, examination findings that show the degree of fixation, gap measurements between fingertips and the palm, and whether the position is favorable or unfavorable matter under the schedule's criteria. Statements from you and those who see you daily describing how joint stiffness, pain, or surgical recovery affect your ability to work, grip objects, walk, or perform routine tasks can also help document the functional impact behind the clinical findings.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
