[Delayed detection of hip dislocation: is the physician to blame?]

Area of Science:

• Pediatric Orthopedics
• Diagnostic Imaging
• Public Health Screening

Background:

• Congenital dislocation of the hip (CDH) is sometimes diagnosed late, despite screening efforts.
• The reasons for diagnostic failures in early CDH detection remain unclear.
• Newborn hip screening may not always identify instability, necessitating follow-up examinations.

Purpose of the Study:

• To explore the challenges in early diagnosis of congenital dislocation of the hip.
• To discuss the implications of delayed diagnosis and treatment.
• To review current screening methods and their limitations.

Main Methods:

• Review of clinical examination protocols for neonatal hip screening.
• Analysis of the role of radiography and ultrasonography in early CDH detection.
• Discussion of diagnostic accuracy and limitations of ultrasound.

Main Results:

• Radiographs at birth are typically normal; systematic pelvic radiography is not recommended for neonates.
• Early ultrasound is sensitive but lacks specificity for dynamic hip disorders.
• Failure to diagnose CDH is a significant cause of litigation against pediatricians in the US.

Conclusions:

• Accurate diagnosis requires a comprehensive history, physical exam, and appropriate imaging.
• Early recognition and treatment of CDH lead to better functional and radiological outcomes.
• Delayed treatment increases the complexity of hip relocation and risk of secondary acetabular dysplasia.
