Primary epiphyseal and metaepiphyseal tubercular osteomyelitis in children A series of 8 case.

UNLABELLED

Clinical series of primary epiphyseal and metaepiphyseal tubercular osteomyelitis are few. The purpose of our study was to retrospectively review the presentation, healing response and functional results of 8 such cases in children.

MATERIAL AND METHODS

The patients were evaluated for pain, deformity, range of motion, limb length discrepancy (if any) and recurrence. Serial radiographs of the region were studied to see remineralization, obliteration of radiological lesions, status of physis and remodeling of the growth plate.

RESULTS

The mean patient age was 7.1 years. Average follow up was 3.7 years. The mean duration of symptom before presentation was 2.9 months (range, 0.5-8 months). Knee region was involved in 4, distal radius in 2, shoulder and distal fibula in 1 patient each. The lesions were either localized or diffuse depending upon physeal involvement and osseous destruction. At the last follow up, the involved joints were painfree and had useful range of motion. Limb length lengthening was seen in all knee patients. The diffuse variety resulted in premature physeal closure. The residual lucencies persisted for several years without any clinical manifestations.

CONCLUSIONS

Primary epiphyseal and metaepiphyseal tuberculosis was relatively uncommon. The clinical outcome was good following curettage and multidrug antitubercular therapy. The epiphyseal and metaphyseal lucencies persisted for several months even after successful treatment. The diffuse variety lead to premature physeal closure. Limb length lengthening was common sequelae of tuberculosis of knee region.
