Systematic radiographic evaluation of tibial hemimelia with orthopedic implications

Pediatr Radiol. 2017 Apr;47(4):473-483. doi: 10.1007/s00247-016-3730-8. Epub 2017 Jan 3.


Tibial hemimelia is a rare lower-extremity pre-axial longitudinal deficiency characterized by complete or partial absence of the tibia. The reported incidence is 1 in 1 million live births. In this pictorial essay, we define tibial hemimelia and describe associated conditions and principles of preoperative imaging assessment for a child with tibial hemimelia. We also indicate the imaging findings that might influence the choice of treatment, describe the most widely used classification systems, and briefly discuss current treatment approaches.
