Tuberculous dactylitis, also known as “spina ventosa,” is a rare form of tuberculosis that affects the bones in the fingers or toes. It primarily occurs in children but can also affect adults. Understanding this condition, its causes, symptoms, and available treatments is essential for prompt diagnosis and effective management.
Tuberculous dactylitis is a type of tuberculosis infection that specifically targets the bones in the fingers or toes. Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis, which usually affects the lungs but can spread to other parts of the body, including bones.
Types of Tuberculous Dactylitis:
There is no specific classification for types of tuberculous dactylitis, as the condition primarily affects the bones in the fingers or toes. However, the severity of the disease can vary depending on factors such as the extent of bone involvement and the individual’s overall health.
Causes of Tuberculous Dactylitis:

- Biopsy of affected tissue
- Histopathological examination
- Immunological tests
- Tuberculosis culture
- Bone scan
- Gallium scan
Non-pharmacological Treatments for Tuberculous Dactylitis:
- Immobilization of the affected finger or toe with splints or braces
- Physical therapy to improve range of motion and strength
- Occupational therapy to assist with activities of daily living
- Use of supportive devices such as crutches or walkers
- Application of cold packs to reduce swelling and pain
- Elevating the affected limb to reduce swelling
- Dietary modifications to promote healing and support immune function
- Adequate rest and avoidance of activities that worsen symptoms

Surgeries for Tuberculous Dactylitis:
- Incision and drainage of abscesses
- Debridement of necrotic tissue
- Bone resection to remove infected bone
- Joint aspiration to relieve pressure and pain
- Soft tissue reconstruction
- Joint fusion to stabilize the affected joint
- Arthroplasty to replace damaged joints
- Osteotomy to realign bones
- Bone grafting to promote bone healing
- Amputation in severe cases of bone destruction or infection spread
Preventive Measures for Tuberculous Dactylitis:
- Vaccination with Bacille Calmette-Guérin (BCG) vaccine
- Screening and treatment of latent tuberculosis infection
- Avoidance of close contact with individuals known to have active tuberculosis
- Promotion of good hygiene practices, including regular handwashing
- Adequate nutrition to support immune function
- Prompt identification and treatment of tuberculosis cases in the community
- Education about tuberculosis transmission and prevention strategies
- Implementation of infection control measures in healthcare settings
- Provision of adequate housing and living conditions
- Promotion of smoking cessation and alcohol moderation
When to See a Doctor:
It is important to seek medical attention if you experience any of the following:
- Persistent swelling, pain, or redness in the fingers or toes
- Difficulty moving the affected limb
- Fever, night sweats, or weight loss
- Drainage of pus from the affected area
