Orthopaedic implications of multiple gestation pregnancy with triplets.

Abstract

Intrauterine crowding has been implicated as a risk factor in several orthopaedic conditions, such as developmental dysplasia of the hip (DDH), metatarsus adductus, and torticollis. The goal of this study was to see whether orthopaedic conditions associated with intrauterine crowding were more frequent in multiple gestation pregnancies, specifically in triplets. The authors reviewed their experience over a 10-year period with 261 children who were products of triplet pregnancies. They surveyed 13 orthopaedic conditions and found only one condition, torticollis, that had a greater incidence than that reported in single gestation pregnancies. A 0% incidence of DDH was found in these patients. Routine ultrasound screening cannot be recommended in these patients based on these results.
