Ossification of the posterior longitudinal ligament

Disease Description (Causes and Symptoms)

• Definition: A femoral (hip) fracture is a fracture of the hip region of the thighbone (e.g., including the femoral neck), referring to a fracture in an area important for weight-bearing and walking.
• Causes/Pathophysiology:
  • In older adults, reduced bone strength due to osteoporosis can cause a fracture even from a minor fall (low-energy trauma).
  • In younger people, it occurs due to traffic accidents or high-energy trauma.
  • Some cases may occur as pathological fractures (e.g., due to bone tumors) or stress fractures.
  • Femoral neck fractures may damage the blood supply, creating a risk of avascular necrosis (AVN) of the femoral head.
• Main symptoms:
  • Pain at the injury site (especially in the hip/buttock area), leg deformity, a difference in leg length (shortening), and swelling.
  • Inability to move the leg or inability to walk due to severe pain.
  • In patients with osteoporosis, a “hairline fracture” with little displacement may be difficult to detect initially on X-rays (a radionuclide scan or MRI may be necessary).

Treatment Methods

• Diagnostic tests:
  • Standard: X-ray imaging of the fracture site.
  • If necessary: Bone scan (radionuclide scan), CT, or MRI (especially when the fracture is unclear on X-rays).
• Conservative treatment:
  • In cases of nondisplaced or low-risk hairline fractures, management may include limited weight-bearing, a brace, pain management, and osteoporosis treatment (indications are limited).
• Surgical treatment (standard approaches):
  • Internal fixation: Fixation of the fracture with screws or pins (e.g., multiple cancellous screws, dynamic hip screw, etc.)—for the purpose of securing stability. However, follow-up is also necessary in some cases (e.g., redisplacement may occur in approximately 15% after screw fixation).
  • Joint replacement: Hemiarthroplasty or total hip arthroplasty may be considered when the fracture is severely displaced or, in older adults, when the condition of the joint is poor.
  • Evaluation of damage to the blood supply of the femoral head after surgery (including radionuclide scans to check for possible femoral head necrosis) and repeat surgery if necessary.
• Medication treatment and prevention:
  • Pain control (analgesics); antibiotics are used before and after surgery when necessary.
  • Prevention of venous thromboembolism (anticoagulant therapy such as low-molecular-weight heparin) and early ambulation are recommended.
  • Osteoporosis treatment: Calcium and vitamin D supplementation, and consideration of osteoporosis medications such as bisphosphonates.
• Rehabilitation/lifestyle management:
  • Early joint mobilization and walking training (the degree of weight-bearing varies depending on the surgical method).
  • Active management to prevent pressure sores, pneumonia, malnutrition, and cardiovascular complications.
• Precautions:
  • There is a high risk of complications such as bleeding, infection, thrombosis, pneumonia, pressure sores, and malnutrition before and after surgery.
  • Regular outpatient follow-up and continued osteoporosis treatment are necessary after surgery.

Checklist Before an Outpatient Visit (Preparation, Items to Confirm, and Sample Questions)

• Items to prepare/bring:
  • A list of currently prescribed medications (especially anticoagulants, antiplatelet drugs, and osteoporosis medications), including dosing times
  • Records of past medical history (including cardiovascular disease, diabetes, kidney disease, etc.) and previous surgeries
  • Recently obtained imaging (if possible, previous X-ray, CT, or MRI films or CDs)
  • A record of when the fracture occurred and how the trauma happened, pain severity (numeric pain scale), and whether walking is possible
  • Information about daily living (whether the person lives alone and whether assistance is available) and the home environment (stairs, bathroom conditions)
• Information to tell the medical staff before consultation:
  • Whether anticoagulants are being taken (important when planning surgery)
  • Allergies (medications, anesthesia, etc.)
  • Previous osteoporosis treatment and the results of the most recent bone mineral density test
• Sample questions to ask at the outpatient visit (for preparation):
  • “Are the imaging tests I currently have sufficient to decide on surgery?”
  • “How should I stop or adjust the medications I am taking (e.g., aspirin, warfarin)?”
  • “Is surgery necessary, what surgical method would be used, and what is the expected recovery period?”

General Sample Questions to Ask the Doctor

• “Is my fracture severely displaced? Is surgery absolutely necessary?”
• “What risks and complications are expected with surgery? How often do they occur?”
• “How will my pain be managed? Which analgesics do you recommend? What are the side effects?”
• “When will weight-bearing (walking) be allowed? How long will rehabilitation take, and when can I return to daily activities?”
• “When will osteoporosis treatment (medication) begin? Which medication is recommended?”

Sample Questions Tailored to the Disease

• “In my case (based on the imaging findings, age, and underlying conditions), do you recommend internal fixation or artificial joint replacement? Why?”
• “How will the risk of avascular necrosis (AVN) of the femoral head after surgery be monitored, and what treatment will be needed if it occurs?”
