Why is alignment essential in fitting a prosthetic limb?

Alignment is crucial when fitting a prosthetic limb because it directly impacts the biomechanics of the user's movement. Proper alignment ensures that the forces generated during walking or other activities are distributed evenly across the prosthetic limb, which helps to maintain efficient gait patterns and reduces the risk of discomfort or injury. When a prosthetic limb is well-aligned, it allows for better stability and control, ultimately leading to improved overall function and mobility for the user.

In addition, proper alignment can prevent excessive wear on both the prosthetic components and the residual limb. Misalignment often leads to uneven pressure distribution, which can contribute to skin irritation, pain, or other complications for the user over time. Therefore, maintaining correct alignment supports the long-term success of the prosthetic fitting by enhancing both user comfort and device durability.
