Small is challenging; distal femur fracture management in an elderly lady with achondroplastic dwarfism.

[achondroplasia]

Achondroplasia is an autosomal dominant dwarfing condition that represents the most common form of skeletal dysplasia . The disease is caused by a mutation in the gene encoding fibroblast growth factor receptor 3 (FGFR 3 ) found at the p 16 .3 locus on chromosome 4 which results in severe inhibition of subchondral bone growth . Anatomic variations , including articular and periarticular deformities classically seen with this condition , amplify the complexity of fracture fixation . Blood volume loss , age-related bone fragility , component selection and positioning pose serious orthopaedic challenges . Concomitant cardiovascular , respiratory and neurological comorbidities pose additional high -risk perioperative considerations . Despite an estimated prevalence of 1 :25 000 in the general population , there is little literature concerning the operative and postoperative treatment challenges faced by orthopaedic surgeons dealing with fracture management on a patient with this condition . We present a case of an intercondylar femoral fracture in an elderly achondroplastic lady successfully treated with percutaneous screw fixation .
