treatment of proximal humerus varus deformity secondary to neonatal glenohumeral septic arthritis: a case report

Background: proximal humerus shortening and varus can occur secondary to neonatal shoulder septic arthritis and focal fibrocartilage dysplasia. valgus osteotomy of the proximal humerus compensates for a little bite of shortening, and improves the shoulder joint's range of motion. case report: in this study, we present two patients with severe proximal humerus deformity following glenohumeral septic arthritis. both of them underwent valgus osteotomy, and had a satisfactory result in terms of range of motions and cosmesis at five years follow-up. conclusion: treatment of varus deformity of proximal humerus is challenging issue. there are few reports of surgical treatment. sever varus deformity of proximal humerus impacts the motion of shoulder. we reported a novel method of valgus osteotomy of proximal humerus in patients with severe varus deformity secondary to neonatal septic arthritis and long-term clinical follow-up.
