A comparison of the effects of two different techniques on shoulder balance in the treatment of congenital scoliosis: Vertical expandable prosthetic titanium rib and dual growing rod.

Purpose: The purpose of this study is to compare the effects of two different growth guidance techniques (dual growing rod and vertical expandable prosthetic titanium rib [VEPTR]) on shoulder balance, in the surgical treatment of congenital scoliosis.
Materials and Methods: Thirteen patients who were operated due to congenital scoliosis are divided into two groups. The coracoid height difference and clavicular tilt angle difference were measured on standing anteroposterior X-ray images in the preoperative, early postoperative periods, and during the last follow-up.
Results: Clinical improvement in shoulder balance was obtained in VEPTR during the last follow-up, but there was no significance in the comparison among the two groups during the last follow-up.
Conclusion: The effect of the growth guidance techniques on shoulder balance positively contributes in the surgical treatment of congenital scoliosis.
