Thoracic fractures and dislocations in motorcyclists.

Area of Science:

• Orthopedics
• Trauma Surgery
• Radiology

Background:

• Motorcyclists involved in accidents frequently sustain severe, multiple injuries.
• Subtle upper thoracic spine fractures (T3-T8) with or without dislocation are often overlooked.
• Diagnosis is complicated by overshadowing cervical or cerebral injuries and radiographic challenges.

Purpose of the Study:

• To highlight the incidence and diagnostic challenges of upper thoracic spine injuries in motorcyclists.
• To emphasize the importance of early and accurate diagnosis of these subtle fractures.
• To recommend an improved imaging technique for detecting these injuries.

Main Methods:

• Retrospective review of 14 motorcyclists involved in accidents.
• Analysis of 26 thoracic fractures/dislocations, with a focus on injuries between T3 and T8.
• Comparison of injury patterns with a larger trauma study of the thoracic vertebral column.

Main Results:

• Twelve of the 14 motorcyclists had 24 injuries in the T3-T8 region, accounting for 56% of all thoracic injuries studied.
• All identified upper thoracic injuries were flexion-type injuries.
• Diagnosis was delayed up to 48 hours in three cases due to inadequate initial imaging.

Conclusions:

• Upper thoracic spine fractures are a significant component of severe trauma in motorcyclists.
• Delayed diagnosis can result from the subtle nature of these injuries and imaging difficulties.
• Overpenetrated radiography of the upper thoracic region is recommended for all severely traumatized motorcyclists.
