An 8-year review of upper limb congenital differences at a teaching hospital in Jordan: A retrospective study

To review the types of upper limb congenital differences in patients seen in a tertiary hospital in Jordan and to evaluate the effectiveness of the Oberg-Manske-Tonkin (OMT) system.

The medical charts and the X-rays of 222 patients with upper limb congenital differences were reviewed. All these cases were categorized using the OMT classification system.

A careful review of the medical charts identified 222 patients with 295 upper extremity anomalies. The prevalence was 45/10000 patients. The mean age of the patients was 6.18±5.5 years, with a higher prevalence in males 54.1%. most cases were malformations 176 (79%) and of these the radial polydactyly was the most common (18.5%). A total of 28 cases of dysplasia were identified. A total of 15 (6.7%) patients were diagnosed with syndromes, of which Poland syndrome showed the highest frequency at 2.3% of the total. The least presentation was for the deformation anomalies (1.4%).

The malformation category constituted most of the congenital upper extremity difference in this study. Radial polydactyly was the most common in this category. Considering the regional differences, the need for a well-established healthcare infrastructure is a vital step toward managing and improving the outcomes of these patients.
