CPO Patient Evaluation 3

Question 1

When documenting residual limb shape during initial prosthetic evaluation, which shape is considered ideal for prosthetic fitting?

Accepted Answer

Conical or cylindrical with firm distal tissue

Answer

A cylindrical or conical residual limb with well-healed, firm distal tissue provides optimal socket fit and load transfer.

Question 2

Which K-level classification is assigned to a patient who has the ability to ambulate with variable cadence and has the ability to traverse environmental barriers?

Accepted Answer

K3

Answer

K3 describes a community ambulator who can ambulate with variable cadence and traverse most environmental barriers.

Question 3

A practitioner evaluates a patient with C6 spinal cord injury for upper extremity orthoses. Which wrist-hand orthosis function would be most appropriate to restore?

Accepted Answer

Tenodesis grasp utilizing wrist extension

Answer

C6 SCI patients retain wrist extension (radial wrist extensors), which can be harnessed through tenodesis to enable a functional grasp.

Question 4

During evaluation of a patient with a partial foot amputation, which factor most significantly influences the choice of footwear modification versus custom orthosis?

Accepted Answer

Level of amputation and remaining lever arm length

Answer

The level of amputation determines the remaining plantar lever arm, which dictates whether footwear modification or a prosthetic device is needed for propulsion.

Question 5

When assessing a patient's skin for suitability for a prosthetic socket, which finding would most urgently delay prosthetic fitting?

Accepted Answer

Open wound or active skin breakdown

Answer

Open wounds or active skin breakdown contraindicate prosthetic fitting until healing is complete to prevent infection and further tissue damage.
