Insights
Physiotherapy significantly improves the resolution of congenital muscular torticollis in infants. This study found that infants receiving physiotherapy had a higher success rate for congenital muscular torticollis regression compared to those who did not.
Area of Science:
- Pediatric Orthopedics
- Diagnostic Imaging
Background:
- Congenital muscular torticollis (CMT) is a common musculoskeletal disorder in infants.
- Early diagnosis and intervention are crucial for optimal outcomes.
Purpose of the Study:
- To evaluate clinical and sonographic factors influencing the regression of CMT in infants.
- To identify predictors of successful treatment outcomes using follow-up ultrasonography.
Main Methods:
- Prospective study of 80 infants with suspected CMT from 2010-2012.
- Neck ultrasonography was performed for diagnosis and follow-up.
- Statistical analysis correlated clinicosonographic findings with complete resolution.
Main Results:
- Of 61 infants diagnosed with CMT, 34 received physiotherapy and 27 did not.
- Complete resolution was observed in 79.4% of infants who underwent physiotherapy versus 55.6% who did not.
- Physiotherapy showed a statistically significant correlation with complete resolution.
Conclusions:
- Physiotherapy is the sole identified factor influencing the successful regression of CMT in infants.
- Sonographic features like lesion size, volume, echogenicity, and thickness ratio did not correlate with resolution.
Purpose:
No previous study using follow-up ultrasonography for evaluating the factors associated with the successful regression of congenital muscular torticollis in young infants has been published. This study aimed to assess clinical factors and sonographic features potentially influencing regression in patients with congenital muscular torticollis.
Methods:
From January 2010 to December 2012, 80 infants underwent neck ultrasonography because of clinical suspicion of congenital muscular torticollis. We statistically analysed the correlation between complete resolution and clinicosonographic findings when complete resolution was defined as no visible lesion on follow-up ultrasonography.
Results:
Of the 80 infants, 61 had congenital muscular torticollis and all were followed up by ultrasonography: 1) 34 underwent physiotherapy, and 27 of them (79.4%) revealed complete resolution in follow-up; 2) 27 did not undergo physiotherapy, and 15 of them (55.6%) showed complete resolution. A statistically significant correlation was found between physiotherapy and complete resolution, but not between complete resolution and patient sex; size, volume, and echogenicity of the lesion; and thickness ratio.
Conclusions:
Physiotherapy was the only factor influencing complete resolution in young infants with congenital muscular torticollis.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups.
