Frontal head posture in shunt-treated hydrocephalic patients

Area of Science:

• Neurosurgery
• Pediatric Neurology
• Medical Imaging

Background:

• Hydrocephalus is a condition characterized by excess cerebrospinal fluid in the brain.
• Shunt placement is a common treatment for hydrocephalus, but can affect head posture.
• Understanding head posture in shunt-treated patients is crucial for monitoring treatment effectiveness and potential complications.

Purpose of the Study:

• To assess frontal head posture in individuals with hydrocephalus treated with shunts.
• To investigate any correlation between head posture and the laterality (sidedness) of the shunt device.

Main Methods:

• Analysis of natural head position and frontal cephalograms from 55 shunt-treated hydrocephalic patients and 33 healthy controls.
• Utilized a computerized digitizing program (X-METRIX) for precise measurements.
• Key reference angles included ORB/HOR (head to horizontal), CER/VER (cervical to vertical), and CER/CR (craniocervical).

Main Results:

• Shunt-treated hydrocephalic patients demonstrated a statistically significant increase in head skewness compared to controls.
• The observed head skewness was independent of whether the shunt device was placed on the left or right side.
• No significant differences were found in the measured angles related to head position relative to horizontal or vertical planes.

Conclusions:

• Frontal head posture alterations, specifically increased skewness, are prevalent in shunt-treated hydrocephalic patients.
• The side of shunt placement does not influence the development or severity of this head posture abnormality.
• Further research may explore other factors contributing to head posture changes in this patient population.
