Abstract
Developmental coxa vara is a rare disease and the symptoms do not appear at birth, but rather, they appear at the age of walking. Clinically, the symptoms include a waddling gait, limb length discrepancy and frequent weariness. Developmental coxa vara is sometimes associated with skeletal dysplasia. Especially, it is associated with spondylometaphyseal dysplsia and the vertebral bodies and long bones are affected. The authors report here on diagnosing and treating this rare disease and we review the relevant literatures.
Figures and Tables
Figure 1
(A) A radiograph shows coxa vara with decreased neck-shaft angle and increased Hilgenreiner-epiphyseal angle (H-E angle). (B) A radio graph shows spondylometaphyseal dysplasia characterized with platyspondyly. (C) There is a marked sclerosis, flaring of the metaphyseal end of distal tibia and fibula. (D) Irregular areas of metaphyses also present corner fracture on medial aspect of proximal tibia.
