Investigation of the Relationship Between Shoulder Alpha Angle and Humeral Head Displacement Percentage Measured by Ultrasonography in Neonatal Brachial Plexus Palsy Infants With Clinical Parameters
Sponsor: Fatih Sultan Mehmet Training and Research Hospital
Summary
This study will examine infants with a birth-related nerve injury called neonatal brachial plexus palsy, which can affect movement in the arm and sometimes cause the shoulder joint to shift out of its normal position (subluxation). Researchers will use ultrasound imaging to measure the shoulder joint and will compare these measurements with findings from a physical examination, to determine which clinical signs can help predict whether a baby's shoulder will develop this problem. The goal is to help doctors detect shoulder problems earlier, so that treatment can start sooner.

Interventions
Shoulder Ultrasonography
Ultrasonographic measurement of the shoulder alpha angle and percentage of humeral head displacement (PHHD), to be performed at each clinical visit.
Standardized Clinical Examination
Standardized physical examination including passive range of motion, Active Movement Scale, Toronto Test Score, and subluxation-specific clinical signs, to be performed at each visit.
