physeal arrest
Pronunciation: FIZ-ee-al
Premature closure of a growth plate leading to limb length discrepancy or angular deformity.
Full Definition
Physeal arrest refers to the premature cessation of growth at a growth plate (physis) before skeletal maturity. This can occur due to trauma, infection, tumor, or congenital conditions. When growth arrest affects only part of the physis, angular deformity results; when it affects the entire physis, limb length discrepancy occurs. Treatment options include growth plate restoration procedures, corrective osteotomies, or limb lengthening techniques. Early recognition and intervention are crucial for optimal outcomes.
Usage
Usage note: Distinguish from normal physeal closure at skeletal maturity.
