Pediatric clavicle abnormalities

The clavicle is a unique bone and as such it often displays unique pathology. The following is an attempt to summarize pediatric clavicle abnormalities.

Pediatric bone tumors and tumor-like lesions of the clavicle

• majority of clavicular tumors are malignant
• Ewing sarcoma (most common)
• osteosarcoma
• aneurysmal bone cyst
• Langerhans cell histiocytosis

Other clavicle abnormalities found only in infancy and childhood

• birth fracture: see birth trauma
• infantile cortical hyperostosis (Caffey disease)
• congenital pseudoarthrosis of the clavicle
• cleidocranial dysplasia
• short clavicle syndrome
• hooked clavicle: Yunis-Varon syndrome, Meier-Gorlin syndrome

Other clavicle abnormalities that can occur in both children and adults

• anterior subluxation of the sternoclavicular joint
• Friedrich disease (osteonecrosis of medial clavicle)
• hypertrophic osteitis
• chronic multifocal periosteitis and arthropathy
• osteomyelitis

Radiation induced clavicle disease

• pediatric clavicle is particularly vulnerable to local radiation effects
• radionecrosis and lysis
• impaired healing following trauma
• tumor: osteosarcoma, osteochondroma, malignant fibrous histiocytoma
