- Pain
Both problems can be treated by means of open reduction, resection of the pseudoarthrosis, and bone grafting. [8] Resection alone produces pain. Pathophysiology The clavicle is the first bone to undergo membranous ossification. [emedicine.medscape.com]

CONCLUSIONS: Children with atrophic-type CPT can obtain satisfactory foot and ankle function at maturity after successful Ilizarov treatment. [traumaysiniestros.com.mx]
In all cases, conventional treatment by intramedullary-rod and autogenous-iliac bone grafting had failed at least once. We hoped to avoid the use of contralateralfibular grafting or other methods that have not yet been proven effective. [btb.termiumplus.gc.ca]

Prognosis
Involvement of the left side usually occurs with dextrocardia and situs inversus. [13] Bilateral cases can occur but are rare and are typically associated with genetic syndromes. [14, 15] Prognosis The outcome is usually excellent, with prompt healing [emedicine.medscape.com]
Etiology
Etiology The etiology is unknown, and no relation to neurofibromatosis has been demonstrated. Abnormalities in aortic arch angiogenesis have been postulated, which would explain, in part, the right-side distribution. [emedicine.medscape.com]
Epidemiology
Epidemiology Congenital pseudoarthrosis is rare. Fewer than 200 cases have been reported in the English literature. The exact incidence and prevalence are unknown. The abnormality occurs almost entirely on the right side. [emedicine.medscape.com]
Pathophysiology
Pathophysiology The clavicle is the first bone to undergo membranous ossification. It connects the sternum to the acromion and provides support for shoulder function. [emedicine.medscape.com]
