**Question:** In the case of a 70 year old lady with intracapsular fracture of the neck of femur, the ideal treatment would be-
A. Open reduction and internal fixation (ORIF)
B. Intramedullary nailing
C. Excision of the head of femur
D. External fixation
**Correct Answer:** D. External fixation
**Core Concept:**
Intracapsular fracture of the neck of femur refers to a fracture involving the articular surface of the femoral head, where the fracture line passes through the joint capsule. This type of fracture includes subcapital and caput femoris fractures. Treatment options for intracapsular fracture of the neck of femur include various surgical techniques aimed at stabilizing the fracture and restoring joint congruity.
**Why the Correct Answer is Right:**
In the context of an intracapsular fracture of the neck of femur, external fixation is an appropriate treatment option due to the following reasons:
1. **Preservation of soft tissue envelope:** The femoral head is a highly vascularized area, and excessive trauma during surgery can lead to significant soft tissue damage. External fixation allows the preservation of the soft tissue envelope, minimizing soft tissue injury and promoting faster healing.
2. **Stabilization and immobilization:** External fixation provides stable fixation and maintains the position of the fracture fragments, allowing for proper healing. The pins placed on the femur and tibia hold the fracture fragments in place, allowing for adequate healing and restoration of joint congruity.
3. **Convenience and versatility:** External fixation allows for easy adjustment and realignment of the fracture fragments, ensuring optimal positioning for healing.
4. **Avoidance of complications associated with internal fixation:** Internal fixation techniques, such as plates and screws, can lead to complications like pin tract infection, implant-related pain, and implant-related discomfort. External fixation avoids these complications while still providing adequate stabilization and immobilization.
**Why Each Wrong Option is Incorrect:**
A. **Open reduction and internal fixation (ORIF):** Although ORIF can provide excellent stability and reduction, the soft tissue injury associated with the procedure makes it an inappropriate choice for this fracture type.
B. **Intramedullary nailing:** Intramedullary nailing is a suitable technique for intertrochanteric fractures, but it may not be ideal for an intracapsular fracture, as it might disrupt the blood supply to the femoral head, leading to avascular necrosis.
C. **Excision of femoral head:** Excision of the femoral head is not a treatment option as it results in the removal of the femoral head, leading to significant morbidity and loss of function in the affected limb.
D. **External fixation:** As explained above, external fixation is a suitable option for this fracture type, as it provides stability, allows for soft tissue preservation, and avoids the complications associated with internal fixation methods.
**Clinical Pearl:**
In cases of intracapsular fractures, the preservation of soft tissues is crucial for optimal outcomes. While internal fixation techniques may provide excellent stability and reduction, they carry a higher risk of soft tissue injury
