Tuberculosis of the Elbow Region in Pediatric Age Group - Experiences from a Single Centre
1* Department of Pediatric Orthopaedics, Chacha Nehru Bal Chikitsalaya, Geeta Colony, India.
Insights
Pediatric elbow tuberculosis is rare. Early signs like discharging sinus and the "ice cream scoop" appearance predict poor functional outcomes, even with non-operative treatment.
Area of Science:
- Pediatric Orthopedics
- Infectious Diseases
- Radiology
Background:
- Tuberculosis (TB) of the elbow in children is infrequently documented.
- Limited clinical series exist, necessitating further research into its presentation and outcomes.
Purpose of the Study:
- To retrospectively analyze the clinical presentation, radiological healing, and functional results in 30 pediatric patients with elbow tuberculosis.
- To identify prognostic indicators for functional outcomes in pediatric elbow TB.
Main Methods:
- Retrospective review of case records for pretreatment disease presentation.
- Serial radiographic analysis to assess lesion healing and remineralization.
- Functional evaluation including pain, range of motion, and recurrence at final follow-up.
Main Results:
- Mean age was 8.2 years; mean symptom duration was 47 days.
- Discharging sinus and multifocal lesions were observed in some patients.
- The 'ice cream scoop' appearance was associated with worse functional outcomes and decreased elbow flexion arc.
Conclusions:
- Early discharging sinus and the 'ice cream scoop' radiological sign suggest tuberculosis.
- Late presentation and advanced disease, particularly with the 'ice cream scoop' appearance, correlate with reduced elbow flexion arc and poorer functional results.
Background:
Clinical series of tuberculosis of elbow region in children are few. The purpose of our study was to retrospectively review the presentation, healing response and functional results of 30 children.
Methods:
The pretreatment disease presentation was studied from patient's case records. Serial radiographs of the patients were studied to see remineralization and healing of radiological lesions. For elbow's functional evaluation, pain, range of motion and recurrence were observed at final follow up.
Results:
The mean patient age was 8.2 years. The mean duration of symptoms before presentation was 47 days. A discharging sinus was present in 6 patients. Multifocal presentation was found in 7 patients. The lesion was most commonly localized in proximal ulna or lower humerus. The classical 'ice cream scoop' appearance of proximal ulnar metaphysis was noted in 5 elbows. Most elbows were in Martini stage 2 (70%) at the time of presentation. All patients were treated non-operatively. Average follow up after completion of antitubercular therapy was 18.97 months. The resolution of regional osteopenia, sclerosis of lytic lesions, reappearance of bony trabeculae and decrease in size of cavities was the usual sequence of radiological healing. End average elbow flexion arc deteriorated with increasing Martini stage. 'Ice cream scoop lesions' resulted in a worse functional outcome with formation of an irregular proximal ulnar articular surface.
Conclusions:
Restriction of elbow range of motion, early discharging sinus formation and radiological 'ice cream scoop' appearance indicated a tubercular pathology. Late presentation with advanced disease, total joint involvement, and 'ice cream scoop appearance' resulted in decreased elbow flexion arc.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
