Summary
Military free fall operations carry risks of high-energy injuries. A Marine sustained a severe femoral neck fracture, highlighting the potential for trauma in these specialized jumps.
Area of Science:
- Orthopedic surgery
- Military medicine
- Trauma research
Background:
- Military free fall (MFF) is crucial for special operations, but injury patterns are poorly understood.
- Unlike static line paratroopers, MFF operators face risks from prolonged descents and high-velocity impacts during parachute deployment.
- Understanding these unique injury risks is vital for operator safety and tactical effectiveness.
Observation:
- A case report details a 33-year-old Marine Corps Reconnaissance operator.
- The operator experienced a left comminuted basicervical femoral neck fracture.
- This injury occurred during a high-risk military free fall operation.
Findings:
- The comminuted basicervical femoral neck fracture required surgical intervention.
- Cephalomedullary nail internal fixation was performed for treatment.
- The operator achieved a full recovery following the procedure.
Implications:
- This case underscores the severe, high-energy trauma potential in military free fall.
- Femoral neck fractures can occur in operators due to the demands of MFF.
- Findings emphasize the need for continued research into MFF injury patterns and prevention strategies.

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Bones of the Lower Limb: Femur and Patella
4.7K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Free-falling Bodies: Example
31.1K
An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant.
