Study DesignA retrospective, case series.ObjectiveThe aim of this study is to evaluate the concomitant anomalies in patients with Sprengel deformity (SD).Summary Of Background DataSD is the most common congenital anomaly of the shoulder. One or more associated anomalies may coexist in SD patients, similar to congenital scoliosis (CS); however, these anomalies and their relationship have not been studied in detail previously.MethodsSD patients who have applied to our institution between 2005 and 2019 were retrospectively reviewed. The patients were evaluated clinically and radiologically. The patients were divided in two groups as SD patients with CS and without CS, to analyze if these anomalies are present due to CS or SD. Physical examination findings, MRI, CT, and USG reports were analysed for accompanying pathologies. Patients with missing data were excluded. Student-t and Fisher's exact tests were used to compare the groups. Significance value was set as p = 0.05.ResultsNinety patients met inclusion criteria. The most common spinal anomaly was omovertebra, followed by spina bifida and Klippel-Feil. Tethered cord and diastematomiyelia were associated with CS (P = 0.0026 and P = 0.0057, respectively). The most common extra-skeletal anomaly was rib anomalies, followed by urinary and cardiac system anomalies. Rib anomalies were associated with CS (P = 0.00001).ConclusionConcomitant anomalies may accompany SD. The prognosis of SD may be affected by these anomalies. Therefore, patients should be evaluated for possible coexistent congenital anomalies.Level Of Evidence4.
