Unilateral posterior dislocation of the radial head in identical twins
Insights
Congenital radial head dislocation can occur with syndromes. This case suggests isolated unilateral dislocations may be congenital, not posttraumatic, challenging current treatment recommendations for this musculoskeletal anomaly.
Area of Science:
- Orthopedics
- Genetics
- Pediatric Musculoskeletal Conditions
Background:
- Congenital dislocation of the radial head, especially bilateral, is often linked to various musculoskeletal syndromes.
- Current literature largely attributes isolated unilateral radial head dislocations to traumatic origins.
- This perspective influences treatment recommendations, favoring surgical intervention like open reduction.
Abstract:
Congenital dislocation of the radial head, particularly bilateral, is seen in association with many syndromes affecting the musculoskeletal system. The consensus in the literature suggests that all isolated unilateral dislocations are posttraumatic in origin. Recent reports, therefore, recommend that unilateral dislocation be treated by open reduction, despite the benign natural history of the anomaly. We report on identical twins with isolated unilateral posterior dislocation in whom there is little doubt about the presence of the dislocation at birth.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
