Insights
Aneurysmal bone cysts (ABCs) in children's hands are rare. Surgical curettage and bone grafting effectively treated a proximal phalanx ABC, showing excellent outcomes with no recurrence after five years.
Area of Science:
- Orthopedic Surgery
- Pediatric Oncology
- Skeletal Radiology
Background:
- Aneurysmal bone cysts (ABCs) are rare, rapidly growing, destructive benign bone tumors.
- ABCs in the tubular bones of the hand, particularly in the pediatric population, are exceptionally uncommon.
- Optimal treatment strategies for aneurysmal bone cysts remain a subject of debate in medical literature.
Observation:
- A case involving a 2-year-old child with an aneurysmal bone cyst in the proximal phalanx of the middle finger was treated at a tertiary care hospital.
- Diagnostic confirmation involved pre-operative Magnetic Resonance Imaging (MRI), Fine Needle Aspiration Cytology (FNAC), and post-operative histopathology.
- The treatment consisted of surgical curettage of the lesion followed by autologous bone grafting.
Findings:
- The patient underwent a 4-week immobilization period with a short below-elbow slab, followed by a structured physiotherapy regimen.
- Post-treatment follow-up revealed excellent radiological and functional recovery.
- Crucially, there was no evidence of recurrence five years after the initial treatment.
Implications:
- This case highlights the efficacy of curettage and autologous bone grafting as a successful treatment modality for pediatric aneurysmal bone cysts in the hand.
- The findings suggest that this surgical approach can lead to long-term, favorable outcomes, including functional restoration and absence of recurrence.
- Further research into standardized treatment protocols for such rare pediatric bone tumors is warranted to address existing controversies.
Abstract:
Aneurysmal bone cysts associated with tubular bones of the hand are rare and even rarer in the paediatric age-group. They are rapidly growing, destructive benign bone tumors. Multiple treatment modalities for aneurysmal bone cyst have been reported in the literature, but controversy exists regarding optimal treatment. We report a case of aneurysmal bone cyst of proximal phalanx of middle finger in a 2 year old child treated at our tertiary care hospital. The diagnosis was confirmed with pre-operative MRI, FNAC and post-operative histopathology. Curettage of the lesion and autologous bone grafting was performed. The hand was immobilized in a short below elbow slab for 4 weeks followed by physiotherapy. Excellent radiological and functional outcomes were obtained with no recurrence at a 5 year of follow up.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
