Reconstruction of congenital pseudarthrosis of the clavicle with a barrel-shaped mono-cortical iliac crest autograft: A case report

Abstract

BACKGROUND: Congenital pseudarthrosis of the clavicle (CPC) is a rare congenital entity with unresolved aetiology and pathogenesis. Nearly 250 cases have been reported to date. CPC is characterized by a definite defect in the mid-clavicle at birth and is usually diagnosed when the deformity becomes evident in late childhood or adolescence. Surgical management is controversial, especially in asymptomatic children, with various techniques reported in the literature. CASE REPORT: We report a case of a 6-year-old boy who was diagnosed with CPC during a medical examination for primary school enrollment. Operative treatment included debridement of pseudoarthrosis, internal fixation with third tube plate, and barrel-shaped mono-cortical iliac crest autograft. RESULTS: A complete bone union was obtained 9 months after the operation, and satisfactory function and cosmetic appearance were observed 4 years and 3 months postoperatively. CONCLUSION: In our opinion, reconstruction with barrel-shaped mono-cortical iliac crest autograft was an effective and reproducible surgical technique to treat CPC.
