Study Notes
Biomechanics of the Foot and Ankle
- The main goal of reconstructive foot and ankle surgery is to restore function to the appendage, improving the patient’s mobility.
- This chapter focuses on the biomechanics of the foot and ankle, relevant to surgical procedures.
- Biomechanics is a broad discipline covering various areas of study related to the mechanics of a living body, especially the forces exerted by muscles and gravity on the skeletal structure.
- Gait studies and force plate studies commonly utilize milliseconds as the primary unit for time.
- Repeated events over short periods are measured in frequency, expressed in Hertz (Hz), with 1 Hz equating to one cycle per second.
- The mass of an object is typically measured in kilograms (kg).
- The force applied by earth's gravity on a mass of 1 kg is approximately 9.81 N.
- Cadaver studies often simulate body weight by applying axial load to a limb. A 70-kg adult generates a downward force of 686.7 N from gravity.
- The center of mass, often referred to as the center of gravity, is thought to be located slightly anterior to the lumbosacral junction in an upright standing human.
- The moment of force, also known as moment or torque, is calculated as M = F × D, where M represents the moment of force in Newton-meters (N-m), F is the force in Newton (N), and D is the distance in meters (m).
- The angle of the force vector significantly influences the magnitude of the moment of force.
