Tuberculosis of the metacarpals and phalanges of the hand

Skeletal tuberculosis (TB) is less common than the pulmonary form. Involvements of the metacarpals and phalanges of the hand are infrequent. The authors report their experience with treatment and outcome of TB of the metacarpals and phalanges of the hand in 7 patients. There were 4 women and 3 men in the study who ranged in age from 3 to 60 years (average age, 22.7 years). The duration of complaints at presentation ranged from 4 to 17 months (average, 9 months). The most common presentation was pain and swelling. The presumptive preoperative diagnoses were bone tumor in 4 patients, spina ventosa in 2, and chronic pyogenic osteomyelitis in 1 patients. The results of the laboratory examination showed a mild increase in the erythrocyte sedimentation rate. No patient had an active tubercular lesion or history of pulmonary disease. The diagnosis was based on the clinical picture and radiographic features, and was confirmed by open biopsy. No patient had bony debridement or arthrodesis to control the infection. The treatment of all patients began with a 4-drug regimen for 2 months, followed by a 2-drug regimen for 10 months. The mean follow-up was 30.28 months (range, 16-52 months). At the time of the last follow-up, all lesions had healed with no recurrence. The functional results were satisfactory in all patients. One patient with thumb metacarpophalangeal TB had joint irregularity and thumb metacarpal shortening. Arthrodesis was not needed in any patient. TB of the metacarpals and phalanges of the hand can be difficult to diagnose during the early stages. TB should be suspected in cases of long-standing pain and swelling in the metacarpals and phalanges. It is necessary to keep TB in mind when making the differential diagnosis of several osseous pathologies.
