Infantile skeletal skew: the use of ultrasound in management

Area of Science:

• Pediatric Orthopedics
• Neonatal Development
• Medical Imaging

Background:

• Infantile skeletal skew encompasses conditions like plagiocephaly and pelvic obliquity.
• Pelvic obliquity can lead to hip adduction contractures, mimicking dysplasia on radiographs.
• This can cause clinical concern regarding hip instability in infants.

Purpose of the Study:

• To evaluate the utility of early ultrasound in assessing hip development in infants with infantile skeletal skew.
• To determine if ultrasound can alleviate concerns about hip instability in affected infants.
• To track hip development over time in infants with infantile skeletal skew.

Main Methods:

• Prospective study of 18 infants with infantile skeletal skew and concerns about the adducted hip.
• Serial ultrasound assessments of the adducted hip side.
• Final radiographic confirmation of hip development at 18 months.

Main Results:

• Early ultrasound assessment reassured clinicians that the affected hips were 'in joint'.
• No treatment was required, and the condition resolved naturally over several months.
• Final radiographs at 18 months confirmed normal hip development in all studied infants.

Conclusions:

• Early ultrasound is a valuable tool for assessing hip development in infants with infantile skeletal skew.
• It can prevent unnecessary interventions by confirming hip stability.
• Infantile hip concerns related to skeletal skew often resolve spontaneously without treatment.
