When considering taking legal action for possible medical negligence related to delayed reduction in a traumatic hip dislocation, there are many factors that need to be considered.

There are other causes of avascular necrosis. Examples include, but are not limited to: arthritis, cancer, gout, alcohol use, joint injuries and long-term medication use involving corticosteroids, bisphosphonates or statins, a specific type of cholesterol lowering agent. (Kelly, et al., 2014) Medical and medication history must be thoroughly reviewed.

As mentioned last week, AVN can occur within 2 years after the initial injury. The severity of the initial injury, even with reduction under 6 hours, could have caused significant damage resulting in necrosis. In a study of 35 patients with severe posterior dislocations, the rate of AVN was 58.8% in those who had their dislocation reduced more than 6 hours after their injury. There was a 4.8% rate of AVN when reduction occurred within 6 hours. 3 patients developed AVN even though their dislocation was reduced in under 6 hours. (Dwyer, John, Singh, & Mam, 2006). A person’s health and medication history can also influence recovery time and the potential for additional complications. Timely reduction does not guarantee prevention of avascular necrosis.
