Congenital Pseudoarthrosis of Clavicle: A Case Report and Review of Literature

Abstract

Congenital pseudarthrosis of the clavicle (CPC) is considered one of the rare conditions that regularly diagnosed during the first years if life and resulted from the failure of the union process of the ossification nuclei of the clavicle. Surgical management is considered the first line treatment of this condition however, associated with some complications. In this case study, we reported a case of 2- year- old- boy presented with Congenital pseudarthrosis of the clavicle that was treated with conservative management.

Serendipitous Discovery: A Case of Twin Congenital Pseudarthrosis of the Clavicle in Saudi Arabia and Literature Review

“…On the other hand, it predominantly affects the right side for unknown reasons [6]. Only three CPC cases have been reported so far in Saudi Arabia and were diagnosed during childhood [6,8,9]. Patients usually present early in childhood with a painless swelling over the middle third of the clavicle, which tends to increase in size as the child grows [5,9].…”

“…Patients usually present early in childhood with a painless swelling over the middle third of the clavicle, which tends to increase in size as the child grows [5,9]. Differential diagnoses of CPC include obstetric fracture (which tends to rapidly heal with an exuberant callus), cleidocranial dysostosis, neurofibromatosis, and posttraumatic nonunion [5,6,8]. The defining feature of CPC is the existence of a painless lump located above the right clavicle.…”

“…In cases of CPC, the distance between the sternum and acromion is noticeably reduced. This swelling is thought to result from the enlargement of bone ends and the overlapping of these fragments [5,8]. There have been reports that the patients might be asymptomatic during their entire life and with painless and normal shoulder range of motion [2,5].…”

Congenital Pseudarthrosis of the Clavicle: A Case Report and a Hypothesis for the Right-Side Predominance

“…It predominantly affects the right side for an unknown reason. About 323 cases have been reported worldwide [1][2][3]. Most reported cases were diagnosed outside the neonatal period [1,4].…”

“…Most reported cases were diagnosed outside the neonatal period [ 1 , 4 ]. Only two CPC cases have been reported in Saudi Arabia, where both were diagnosed during childhood [ 2 , 3 ]. The CPC is an important differential diagnosis for the common acute clavicular fracture from birth trauma [ 1 , 4 ].…”
