Physeal Bone Bridges
- Discussion:
- growth arrest, partial or complete, w/ progressive angulation &/or shortening ranges
from 30% & 80% of pts;
- shortening & angulation are more related to degree of initial displacement rather
than accuracy of the reduction;
- leg length discrepancy of > 2 cm may develop in 1/3 of pts;
- incidence of growth arrest is high, even with satisfactory reduction;
- angulation more than 5 deg may also develop in 1/3 of pts;
- persistent angular deformity in coronal plane may not correct spontaneously with further growth;
- SH II:
- if asymmetrical growth inhibition follows type II separation, portion of grwth plate underneath
metaphyseal fx is spared;
- if metaphyseal frag is medial, valgus deformity may ensue;
- if metaphyseal frag is lateral, varus angulation may ensue;
- SH III:
- look for vertical fracture line originating from the notch;
- reduction may be unstable and require internal fixation;
Growth disturbances following distal femoral physeal fracture-separations.
