Question 1: A 75-year-old man presents with a fracture of the intracapsular neck of the femur. What is the most common management option for this patient?
- A. Hemiarthroplasty (Correct Answer)
- B. Total Hip Replacement
- C. Dynamic Hip Screw
- D. Conservative Management
Explanation: **Hemiarthroplasty**
- **Hemiarthroplasty** is the most common management for **intracapsular neck of femur fractures** in elderly patients, especially those who are frail or have substantial comorbidities.
- This procedure replaces the **femoral head** with a prosthesis, preserving the native acetabulum, which is sufficient given the higher risk of complications with a full replacement in this age group.
*Total Hip Replacement*
- **Total hip replacement (THR)** is typically reserved for more active elderly patients with **pre-existing osteoarthritis** or for those requiring revision surgery, due to better functional outcomes but higher surgical risks.
- It involves replacing both the **femoral head** and the **acetabulum**,
*Dynamic Hip Screw*
- A **dynamic hip screw (DHS)** is primarily used for **extracapsular femur fractures** (e.g., trochanteric fractures), where the blood supply to the femoral head is largely preserved.
- It involves fixation, which is not suitable for most **intracapsular fractures** due to the disruption of blood supply, increasing the risk of **avascular necrosis** and non-union.
*Conservative Management*
- **Conservative management** (e.g., bed rest, pain control) is generally not recommended for **intracapsular neck of femur fractures** in mobile elderly patients due to high rates of complications such as **deep vein thrombosis**, **pressure ulcers**, and **avascular necrosis**.
- It may be considered only in patients who are **non-ambulatory** or have severe contraindications to surgery.
Question 2: A 26-year-old male presented with proximal 1/3rd fracture shaft of the femur. What is the treatment of choice in this patient?
- A. Hip Spica
- B. Above knee Cast
- C. Above knee Slab
- D. Interlocking Nail (Correct Answer)
Explanation: ***Interlocking Nail***
- **Interlocking nailing** is the treatment of choice for **femur shaft fractures** in adults, providing stable fixation and allowing early mobilization.
- It involves inserting a **metal rod** into the medullary canal of the bone across the fracture site, with screws locking it in place at both ends.
*Hip Spica*
- A **hip spica cast** is typically used for **femur fractures in young children** (under 6 years old) as non-operative management.
- It is **not suitable for adults** due to weight, discomfort, and the inability to maintain adequate reduction and stability for an adult-sized femur.
*Above knee Cast*
- An **above-knee cast** is generally insufficient for **femur shaft fractures** as it does not provide adequate immobilization of the hip joint.
- It is more commonly used for **tibial fractures** or injuries to the knee/lower leg, not for a fracture as high as the proximal femoral shaft.
*Above knee Slab*
- An **above-knee slab** offers even less stability than a full cast and is usually a temporary measure for initial immobilization before definitive treatment or for less severe injuries.
- It would be **inadequate to stabilize a femoral shaft fracture** and prevent displacement.
