The effect of acetabular retroversion on ipsilateral injuries during traumatic hip dislocation

Area of Science:

• Orthopedic Surgery
• Traumatology
• Radiology

Background:

• Traumatic hip dislocations can lead to associated ipsilateral limb injuries.
• The role of native acetabular anteversion in these injuries remains unclear.

Purpose of the Study:

• To investigate the association between native acetabular anteversion angle and the risk of ipsilateral limb injuries in patients with traumatic hip dislocations.

Main Methods:

• Retrospective clinical series of 121 patients with traumatic hip dislocations.
• Acetabular anteversion angles measured on CT scans.
• Analysis of associated knee and femoral head injuries.

Main Results:

• Median acetabular version was 14.7°.
• 23% of patients sustained knee injuries, and 33% sustained femoral head injuries.
• No statistically significant association found between acetabular version and ipsilateral limb injuries (p=0.13).

Conclusions:

• Native acetabular anteversion does not appear to predispose or protect against ipsilateral limb injuries following traumatic hip dislocation.
• Further research is needed to identify other contributing factors to these associated injuries.
