Tuberculous dactylitis
Updates to Article Attributes
Tuberculous dactylitis (also known as spina ventosa) is a skeletal manifestation of tuberculosis.
Epidemiology
Tuberculous osteietis is one of the commonest bacterial osteitis. Typically the dactylitis form affects paediatric age group more often than adults. In children multiple or consecutive bones are involved, compared to a single bone in adults.4
Clinical presentation
Tuberculous dactylitis involves the short tubular bones of the hands and feet in children. It often follows a benign course without pyrexia and acute inflammatory signs as opposed to acute osteomyelitis.
Radiographic features
Plain filmRadiograph
Plain Radiographyradiography is the modality of choice for evaluation and follow up.
Tends to affect the bones distal to tarsus and wrist, upper limb being more commonly involved. Typically the proximal phalanx of the index/middle fingers and middle/ring finger metacarpals are affected.
- involved bone shows a diaphyseal expansile lesion
- a periosteal reaction is uncommon
- healing is by sclerosis and is usually gradual
EtymologyHistory and etymology
This condition was first described by Boyer and Nelaton.
The term spina ventosa derives from spina = short bone and ventosa = expanded with air.
Differential diagnosis
The differential diagnosis includes:
- pyogenic or fungal infections
- syphilitic dactylitis
- sarcoidosis
- hemoglobinopathies
- hyperparathyroidism
- leukemia
