Pelvic Obliquity
A lateral tilt of the pelvis in the coronal plane, often addressed through leg-length discrepancy management or spinal orthotic intervention.
Full Definition
Pelvic obliquity refers to a non-horizontal alignment of the pelvis in the coronal plane, where one iliac crest sits higher than the other. In orthotic services, it commonly arises in documentation relating to leg-length discrepancy correction, seating and positioning systems, and lumbosacral orthotic prescriptions. Editors must recognise the term to ensure it is not confused with pelvic tilt (an anterior or posterior rotation in the sagittal plane) or pelvic rotation (a transverse-plane deviation). It appears in referral letters, multidisciplinary team reports, and functional outcome measures, and its correct use carries clinical and reimbursement implications.
Usage
Usage note: Always verify the plane of deviation when editing; pelvic obliquity, tilt, and rotation are three distinct and non-interchangeable findings.
In Context
- "A 12 mm heel raise was prescribed to correct the functional pelvic obliquity associated with the patient's right-sided leg-length discrepancy." — Orthotic prescription report
- "Editors should note that pelvic obliquity is a coronal-plane finding and must not be substituted with 'pelvic tilt', which describes a sagittal-plane deviation." — Editorial style brief
