Which nerve injury is most likely linked to an acetabulum fracture?

The sciatic nerve is most commonly associated with acetabular fractures due to its anatomical proximity to the hip joint and the structures surrounding it. Injury to this nerve can occur when there is significant trauma to the pelvis or hip, as seen with acetabular fractures. These fractures often result from high-energy traumas, such as car accidents or falls from a height, where the force can lead to direct damage or stretch to the sciatic nerve.

Acetabular fractures can partially displace structures around the hip joint, which can cause pressure or entrapment of the sciatic nerve. Injury to this nerve can lead to symptoms such as weakness in the leg muscles, loss of sensation in the posterior thigh, and potentially an inability to dorsiflex the foot, depending on the severity and location of the injury.

While peroneal nerve injury can also occur in cases of trauma involving the lower extremities, it is more specifically linked to injuries at the fibular head rather than acetabular fractures. The radial nerve and cauda equina injuries are not typically associated with hip or pelvic fractures; radial nerve injuries are usually related to upper extremity trauma, and cauda equina syndrome involves lower spinal cord injuries. Thus, given the connection between
