Question

What is the most common acetabulum fracture pattern correlated with nerve injury?

Answer 1

The most common acetabulum fracture pattern associated with nerve injury is that which involves the posterior column of the acetabulum, potentially affecting the sciatic nerve. For femoral neck fractures within the hip joint capsule, avascular necrosis can occur due to disrupted blood supply, leading to bone and cartilage death.

Step-by-step explanation:

The most common acetabulum fracture pattern associated with nerve injury, particularly sciatic nerve injury, is a fracture that involves the posterior column of the acetabulum. During such fractures, the displacement of the bone can have a direct impact on the nearby sciatic nerve, leading to injury or dysfunction. The severity of the injury to the nerve can vary depending on the exact nature of the fracture. Commonly, these types of fractures are a result of high-energy trauma and may be associated with significant morbidity.

When considering fractures of the femoral neck within the capsule of the hip joint, a potential consequence is a disruption of the blood supply that can result in avascular necrosis (AVN) or osteonecrosis. This condition leads to the death of bone and cartilage tissue due to loss of blood flow and can result in severe arthritis or the need for hip replacement surgery. AVN is a serious complication that requires prompt and effective management to prevent long-term disability.A possible consequence following a fracture of the femoral neck within the capsule of the hip joint is necrosis of the femoral head or neck due to a disruption of blood supply. This can result in bone and cartilage death and lead to significant mobility issues and the need for surgical treatment. Hip fractures, including fractures of the femoral neck, are associated with increased rates of morbidity and mortality.

Answer 2

Step-by-step explanation:

According to a study published in the Journal of Orthopaedic Trauma, the most common fracture pattern associated with nerve injury in acetabulum fractures is **transverse posterior wall** ¹. The study also found that obesity was more common in patients with nerve injuries (59% vs. 30% in those without nerve injury) ¹. However, obesity was not related to age or sex ¹.

The study further reports that 32 patients (3.3%) experienced nerve injury with 24 (78%) resulting from trauma and 23 with an associated posterior hip dislocation .Eight injuries (25%) were iatrogenic . Thirty-one (97%) occurred in patients with operative fractures ¹. Sixty-five percent of sciatic nerve injuries were to the common peroneal division only, while none were isolated to the tibial division . All iatrogenic injuries occurred after the ilioinguinal approach

Overall, 50% of patients experienced partial nerve recovery and 22% had complete recovery ¹. However, 24% of patients with sciatic or common peroneal injuries had no recovery ¹. The average Musculoskeletal Function Assessment scores for patients with nerve injuries was 32, similar to those without (33)
