Abstract
PURPOSE: In the present study, we aimed to analyze the demographic data and deformity types of patients with congenital upper limb anomalies who underwent operations in our clinic.
MATERIALS AND METHODS: We retrospectively evaluated 110 patients (66 males, 44 females) who underwent surgical treatment in our clinic between 2009 and 2021. The deformities were grouped using the Classification of Swanson for Congenital Anomalies of Upper Limb, Modified. We evaluated the patients’ age, sex, hand-foot involvement, and incidence in both limbs. Polydactyly and syndactyly cases were evaluated separately.
RESULTS: The mean age was 54.7 months (3 months – 38 years). Overall, 34 (30.9%) patients were toddlers (1-2 years), 28 (25.5%) were preschoolers (3-5 years), and 23 (20.9%) were infants (1-12 months). There were 66 (60%) male patients and 48 (40%) female patients. Regarding the subgroups, 42 (38.2%) patients had polydactyly: 25 (59.5%) had preaxial polydactyly, 13 (30.9%) had postaxial polydactyly, and 4 (9.5%) had central polydactyly. Among the patients with preaxial polydactyly, Wassel Type 4 was the most common with 13 (52%) patients. Being the second most common condition, syndactyly was seen in 23 (20.9%) patients. The most common site of syndactyly was between the third and fourth digits in 11 (47.8%) patients. Amniotic band syndrome ranked third with 17 (15.5%) patients.
CONCLUSION: Unlike the previous reports in the literature, we observed polydactyly as the most common congenital hand anomaly in our series. Syndactyly was the second most common condition in our series.
