Abstract
Background
In 1975, King Chulalongkorn Memorial Hospital (KCMH) in Bangkok, Thailand, published data on common orthopedic problems in neonates.
Objectives
To determine the more recent incidence of these conditions and to compare the results with those reported 40 years ago by KCMH. The data were also compared with a recent report from Siriraj Hospital.
Methods
We reviewed medical records of newborn infants from 2012 to 2016, all of whom were born in KCMH with deformities of upper and lower extremities or other birth-related injuries. The cases were grouped according to International Classification of Diseases, 10th edition. The incidence of common neonatal orthopedic problems was calculated as cases per 1,000 live births and compared, using a chi-squared test, with the earlier data from KCMH and with the data recently reported by Siriraj hospital.
Results
Of the 24,825 live births, 54% were male and 46% were female. The average birth weight was 3,052.2 ± 516.1 g (range, 535–5,320 g) for infants. The most common deformity was postural clubfoot, followed by calcaneovalgus and hip dysplasia, with incidences of 1.37, 0.93 and 0.52 per 1,000 live births, respectively. The incidence of calcaneovalgus, metatarsus adductus, and clubfoot was lower than in the 1975 study and in the report from Siriraj. In all 3 studies, the incidence of birth-related injury was similar and clavicular fracture was the most common, with a rate of 1.3/1,000 live births.
Conclusion
The incidence of common neonatal orthopedic problems varies among institutions. Birth-related injury is a major challenge. The results may be utilized as updated data and as a starting point for parental education.
