Objective: The soft cervical collar has been prescribed for whiplash injury but has been shown to be clinically ineffective. As some authors report superior results for managing whiplash injury with a cervical brace, we were interested in comparing the mechanical effectiveness of the soft collar with a rigid cervical brace. Therefore, the purpose of this study was to measure ranges of motion in subjects without neck pain using a soft cervical collar and a rigid brace compared with no orthosis.
Methods: Fifty healthy subjects (no neck or shoulder pain) aged 22 to 67 years were recruited for this study. Neck movement was measured using a cervical range of motion goniometer. Active flexion, extension, right and left lateral flexion, and right and left rotation were assessed in each subject under 3 conditions: no collar, a soft collar, and a rigid cervical brace.
Results: The soft collar and rigid brace reduced neck movement compared with no brace or collar, but the cervical brace was more effective at reducing motion. The soft collar reduced movement on average by 17.4%; and the cervical brace, by 62.9%. The effect of the orthoses was not affected by age, although older subjects had stiffer necks.
Conclusion: Based on the data of the 50 subjects presented in this study, the soft cervical collar did not adequately immobilize the cervical spine.

Case: We present a marginal mandibular branch of the facial nerve palsy that occurred in a 55-year-old woman from external compression of a rigid cervical collar. This nerve palsy occurred after less than 24 hours of collar utilization and was treated conservatively with delayed recovery.
Conclusion: A marginal mandibular branch of the facial nerve palsy is a rare complication of cervical collar usage with only 1 other documented case in the literature.

The main aim of this work is to evaluate the mechanical properties of additive manufactured polymeric parts joined with standard plastic parts through structural adhesives. The primary advantage of this technique is its ability to significantly increase the size of the final assembly by using additive manufacturing (AM) for complex joints and inexpensive, reliable extruded plastic parts for load-bearing components. This hybrid assembly combines the flexibility and shape adaptability of AM with the structural strength and cost-effectiveness of extruded polymer parts, resulting in a final design that performs comparably to the base material.

Purpose: The management of odontoid fractures in adult patients has been widely described. However, there is sparse literature about this injury in the pediatric population. This study aimed to review published literature regarding the management and outcomes of pediatric odontoid fractures to develop a stepwise treatment algorithm.
