Worsening of deformity with complications such as chronic skin ulcers and bone exposure is common.

The emergence of growth-friendly techniques has greatly benefited patients with early-onset deformity, allowing for correction and control of deviation without interrupting trunk growth, which is often already compromised in these patients.
