Orthopaedic implications of multiple gestation pregnancy with triplets

Area of Science:

• Orthopedics
• Neonatal care
• Public health

Background:

• Intrauterine crowding is a known risk factor for pediatric orthopedic conditions like developmental dysplasia of the hip (DDH), metatarsus adductus, and torticollis.
• Multiple gestation pregnancies, particularly triplets, may experience increased intrauterine crowding.
• Understanding orthopedic condition prevalence in triplet pregnancies is crucial for targeted screening and intervention.

Purpose of the Study:

• To investigate the incidence of orthopedic conditions associated with intrauterine crowding in triplet pregnancies.
• To compare the frequency of these conditions in triplets versus singletons.
• To determine if routine screening for specific orthopedic conditions is warranted in neonates from triplet pregnancies.

Main Methods:

• Retrospective review of 261 children from triplet pregnancies over a 10-year period.
• Survey of 13 specific orthopedic conditions.
• Comparison of incidence rates with reported data from single gestation pregnancies.

Main Results:

• Torticollis was the only orthopedic condition with a higher incidence in triplet pregnancies compared to singletons.
• Developmental dysplasia of the hip (DDH) showed a 0% incidence in the studied triplet population.
• No significant increase in other surveyed intrauterine crowding-associated orthopedic conditions was observed.

Conclusions:

• While torticollis may be more prevalent, routine ultrasound screening for DDH and other related orthopedic conditions in triplet pregnancies is not supported by these findings.
• The low incidence of DDH in this cohort suggests that specific orthopedic screening protocols for triplets may need re-evaluation.
• Further research could explore the multifactorial causes of orthopedic conditions in multiple gestations.
