Child with right lower limb deformity.

Patient Data

Age: Child
Gender: Male

Congenital right lower limb anomaly, in the form of:

  • absent/aplastic fibula
  • hypoplastic tibia with deformity of the distal tibial epiphysis resulting in convexity with lateral and posterior slope of its distal joint surface, with subsequent talipus equinovalgas deformity of the foot and ankle
  • small dysmorphic right talus and calcaneus
  • absent metatarsals and phalanges of the lateral two toes

Case Discussion

Fibular hemimelia is a congenital lower limb deformity which has been divided into two types:

  • type 1: minimal hypoplasia of the fibula
  • type 2: complete absence of the fibula

Fibular hemimelia could be an isolated anomaly or associated with proximal focal femoral deficiency, absence of lateral rays and phalanges of lateral toes, syndactyly and polydactyly.
