Pelvic fractures represent a significant transfer of kinetic energy to the body, and more than 80% of patients with unstable pelvic fractures have additional musculoskeletal injuries. A systematic approach with prompt intervention is critical in the initial management of patients with pelvic fractures. If intra-abdominal bleeding is suspected, diagnostic peritoneal lavage, focused assessment with sonography for trauma, or a CT examination is usually performed. ⋯ The orthopaedic surgeon provides prompt stabilization using external immobilizers, external fixation, or traction. The bladder, urethra, and nerve roots have an intimate location within the pelvis and are predisposed to injury in patients with pelvic fractures. Appropriately identifying associated abdominal, urologic, or neurologic injuries will provide important opportunities to reduce patient morbidity and improve long-term outcomes.

Multimodal pain management techniques using femoral and sciatic nerve blocks can dramatically improve a patient's experience after total knee arthroplasty. Nerve blocks reduce postoperative pain and the need for parenteral opioids and result in fewer medical complications associated with opioid use. ⋯ Although it is difficult to isolate the added benefit of sciatic nerve blocks, there is a growing body of evidence for using femoral and/or sciatic nerve blocks as part of a multimodal approach to pain management. With many years of experience and published results on thousands of patients, it is clear that the risks of peripheral nerve blocks are minimal, whereas the benefits are substantial.

Although definitive fixation of anterior pelvic ring injuries is usually referred to an orthopaedic trauma surgeon or a surgeon proficient in pelvic surgery, all orthopaedic surgeons should be familiar with the initial management and resuscitation of patients with high-energy pelvic ring injuries. The initial treatment may be limited to sheet or binder application in the emergency department to allow transfer of the patient to a trauma center or the application of an external fixator by an on-call surgeon, even though that surgeon may not be responsible for definitive fixation. It is important to understand the general principles and approaches used at the time of definitive surgery because decisions made by the initial treating physician may affect (or limit) the ability of the orthopaedic traumatologist to provide definitive care.

Unstable posterior pelvic ring injuries are commonly treated with percutaneous iliosacral screw fixation. Despite the efficiency of the minimally invasive technique, complications and failures occur. To maximize reduction quality and fixation stability, open techniques for pelvic ring fixation exist. Timing, approaches, clamp positioning, and implant options determine the effectiveness of the open techniques.

There is considerable overlap in the clinical and imaging presentation of general orthopaedic conditions and musculoskeletal neoplasms. At centers that treat orthopaedic oncologic conditions, it is not uncommon to see patients with spine and extremity tumors previously treated for presumed general orthopaedic ailments. It is important for orthopaedic surgeons to understand how to interpret commonly ordered radiographic studies (radiographs, MRIs, and CT scans) as they relate to bone and soft-tissue tumors, to be familiar with the imaging appearance of common musculoskeletal lesions in the extremities and spine, and to understand what imaging findings should trigger a referral to an orthopaedic oncologist.
