Objectives: This study reports the surgical outcomes in a patient cohort with congenital pseudarthrosis of the clavicle (CPC).

Patients and methods: A total of nine pediatric patients (5 males, 4 females; mean age: 4.43 years; range, 2 to 12 years) who were diagnosed with CPC and treated surgically with a minimum one-year follow-up between January 1996 and December 2018 were retrospectively analyzed. The patients were divided into two groups according to the fixation method as the Kirschner wire (K-wire; Group A, n=2) or stabilization with a plate (Group B, n=7). The physical function and symptoms were evaluated using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scale.

Results: The mean age at the time of diagnosis was 2.95 (range, 0 to 12) years. Six cases were atrophic pseudarthrosis and three cases were hypertrophic. Radiographic consolidation occurred in all cases with a mean duration of 103.8±39.1 days, indicating no significant difference between the groups (p>0.05). Complications registered were a K-wire breakage in a patient in Group A and an internal fixation plate loosening in a patient in Group B. The mean postoperative follow-up was 2.98±1.82 years. The QuickDASH score was 0 points in all patients.

Conclusion: The early surgical indication based on refreshment of the pseudarthrosis focus, with bone autograft interposition when a failure exists to restore adequate clavicular length, and fixation are reliable alternatives with favorable clinical and radiological results in the mid- and long-term with fewer complications.
