The chapter discusses practical approaches to amputating a severely damaged or infected thigh at the hip joint. It begins with an overview of when such drastic measures are necessary—typically after extensive crush injuries or gunshot wounds where immediate life-saving action is required. The text emphasizes controlling hemorrhage as the first step, followed by careful dissection and ligature of major vessels to ensure a bloodless field for clean amputation.
<Callout type="important" title="Critical First Step">Control hemorrhage immediately before proceeding with any surgical intervention.</Callout> The chapter then delves into Senn’s method for bloodless hip amputations, which involves making an initial incision over the great trochanter and carefully dividing muscles and ligaments to expose the femur. Special attention is given to handling the obturator externus tendon and cleaning the digital fossa.
<Callout type="risk" title="High Risk">Failure to properly control bleeding can lead to severe blood loss or death.</Callout> The text also covers how to safely divide the common femoral vein and artery, ensuring no further significant bleeding occurs. Finally, it describes the use of an elastic constrictor tube to isolate the posterior segment of the thigh for amputation.

Key Takeaways
- Immediate hemorrhage control is essential before any surgical intervention.
- Senn’s method provides a reliable approach for bloodless hip amputations.
- Proper muscle and ligament division ensures a clean bone exposure.
Practical Tips
- Use an elastic constrictor tube to isolate the posterior thigh segment effectively.
- Carefully manage the obturator externus tendon during dissection to avoid complications.
- Ensure thorough cleaning of the wound before proceeding with amputation.
Warnings & Risks
- Failure to control bleeding can lead to severe blood loss or death.
- Improper handling of muscles and ligaments may result in incomplete exposure of the femur.
- Inadequate preparation for such procedures can increase risk and complications.
Modern Application
While modern medical practices have advanced significantly since 1915, understanding historical techniques like those described here remains valuable. These methods provide a foundation for emergency amputations in situations where conventional medical care is unavailable or delayed. The principles of hemorrhage control and careful surgical technique remain crucial today.
Frequently Asked Questions
Q: What are the initial steps to take before performing an emergency hip amputation?
The first step is always to control hemorrhage, followed by cleaning the wound as much as possible. If necessary, pack the wound with gauze and wait for the patient's condition to stabilize.
Q: How does Senn’s method ensure a bloodless amputation?
Senn’s method involves dividing the common femoral vein and artery between two ligatures. This stops further bleeding, making it easier to proceed with the amputation without significant loss of blood.
Q: What role does an elastic constrictor tube play in hip amputations?
The elastic constrictor tube is used to isolate the posterior segment of the thigh by constricting both arterial and venous circulation, ensuring a bloodless field for the operation.
Q: Why is careful handling of the obturator externus tendon important during hip amputations?
Improper handling can lead to complications such as incomplete exposure of the femur or damage to surrounding tissues. Careful division and management are necessary to ensure a clean surgical field.
Q: What is the significance of controlling bleeding from the crucial anastomosis behind?
Controlling bleeding from this area is critical because it can lead to significant blood loss if not managed properly. The vessels forming the crucial anastomosis are easily accessible and should be ligated to prevent further hemorrhage.
