What are some of the treatments for hip fractures?

Surgery. Most fractured hips require surgery because they heal poorly, or not at all without some form of hardware to hold the broken bones in place. Some, especially in older patients, require replacement.
Depends. The most conservative thing is to remain in traction and hope it heals, a very uncommon choice. Surgical options can be screws placed via xray guidance, or partial or complete joint replacement. Orthopedic surgeon will advise. Anesthesia choices general vs spinal or epidural. Anesthesiologist will discuss.
