Coronal Plane Control
Orthotic management of mediolateral (side-to-side) movement, particularly inversion and eversion at the subtalar and ankle joints.
Full Definition
Coronal plane control describes an orthosis's ability to limit, guide, or correct motion occurring in the coronal (frontal) plane — the plane dividing the body into front and back halves. In the context of orthotic services, this most commonly refers to control of inversion and eversion at the hindfoot and mediolateral stability at the knee. Editors encounter the term in device specifications, insurance pre-authorisation letters, and clinical audit reports. Confusing coronal plane control with sagittal plane control is a frequent editorial error that alters the clinical meaning of a document significantly. The term is often used alongside valgus and varus correction descriptions.
Usage
Usage note: Distinguish carefully from sagittal and transverse plane control; each has distinct clinical implications that affect document accuracy.
In Context
- "A medial flange was added to the shell to enhance coronal plane control and resist hindfoot eversion." — Device prescription letter
- "The report incorrectly described the device as providing sagittal plane control when the clinical notes clearly indicated coronal plane control was the primary goal." — Proofreading feedback memo
