Abstract
Tuberculosis of short tubular bones is uncommon after childhood. “Spina Ventosa” is considered the classical radiological presentation and hallmark of this disease. The short tubular bones are uncommon loci for the manifestation of adult skeletal TB. We report our experience with 31 cases of tuberculosis of hand (excluding wrist) with the intention to call attention to its occurrence in infrequently documented areas, to stress upon its morphologic variability and to illustrate little emphasized radiological signs.
Material & Methods: (n=31) Age range 1–68 years; M:F – 11:20; duration of symptoms-3 weeks to 2 years; history of Incision and Drainage before presentation −12 (38%) cases; Epitrochlear lymph node enlargement seen in 22 (71%) cases. Radiologically-classical spina ventosa seen in 5 cases; primarily diaphyseal involvement of metacarpal in 9, lesion in metacarpal head in 4, juxtraarticular metacarpal head erosion in 3, metacarpal base lesion in 3, phalangeal involvement in 2, carpometacarpal joint involvement in 2 and primarily small joint involvement in 3 cases. Majority of them were treated conservatively. Follow up is 1–5 years.
Discussion: Tuberculosis of hand might mimic several other inflammatory or neoplastic diseases. Disease might be initially painless and constitutional symptoms may be absent. Rapid collection because of lax skin on the dorsum of hand might tempt the surgeon for incision and drainage. FNAC of Epitrochlear lymph nodes may be diagnostic which may be enlarged in 60–70% cases. The clinicoradiological presentation, differential diagnosis and treatment with special reference to dynamic finger traction will be discussed.
