Congenital muscular torticollis: evaluation and classification

Area of Science:

• Pediatric Neurology
• Musculoskeletal Disorders
• Rehabilitation Medicine

Background:

• Congenital muscular torticollis (CMT) is a common condition in infants.
• Early diagnosis and intervention are crucial for optimal outcomes.
• Ultrasonography plays a role in classifying CMT and guiding treatment.

Purpose of the Study:

• To retrospectively analyze clinical presentation, treatment, and outcomes of 311 infants with CMT.
• To evaluate outcomes based on an ultrasonography-based classification.
• To determine factors influencing treatment success in congenital muscular torticollis.

Main Methods:

• Retrospective review of 311 infants diagnosed with congenital muscular torticollis between 1995 and 2003.
• Standardized evaluation including cervical ultrasonography for classification into subgroups.
• Assessment of clinical presentation, associated anomalies, treatment (passive range of motion), and outcomes.

Main Results:

• Two primary clinical subgroups identified: sternomastoid tumors (85%) and postural torticollis (15%).
• Mean age at diagnosis was 2.3 months.
• 95% of patients achieved total resolution, and 5% achieved subtotal resolution with conservative treatment.

Conclusions:

• The majority of infants with congenital muscular torticollis experience complete symptom resolution.
• Conservative management, particularly passive range of motion exercises, is highly effective.
• Treatment success is significantly influenced by the patient's age at exercise initiation and ultrasonographic findings.
