Abstract Genu valgum is common in pediatric orthopaedics. With the exception of physiological deformities that resolve with observation alone, it may progress, adversely affecting gait and function. Joint laxity and instability may ensue, along with compensatory or confounding deformities. Provided the physes are still growing, guided growth is an excellent and proven technique for correcting alignment, restoring the mechanical axis and mitigating the effects of the ground reaction force. Alleviated from excess and eccentric compression as well as shear forces, previously stressed physes can respond and grow in a surprisingly normal fashion. Limb length inequality (in the range of 2-5 cm) may be dealt within a similar fashion. The modular and reversible nature of guided growth makes this a most versatile strategy in dealing with a wide variety of clinical problems. The simplicity and cost-effectiveness of this minimally invasive technique make it an attractive alternative to more complex methods of limb deformity correction. |
