Internal fixation is not an ideal solution for Charcot patients because they usually have poor bone quality, which makes it difficult for the screws or plates to hold the bones together. In addition, infection is usually present in Charcot patients, which can further complicate the healing process. Moreover, Charcot patients often have mechanical instability, meaning that their bones are not stable enough to support internal fixation. Lastly, these patients have a difficult time healing due to their underlying medical condition.

The greatest advantage of external fixation is the ability to obtain and maintain stability. This means that the external fixation system can effectively stabilize and support the injured or fractured bone throughout the healing process. Unlike other options, such as casts or internal fixation, external fixation allows for precise control and adjustment of the stability needed for proper healing. This advantage is crucial in ensuring that the bone heals correctly and minimizes the risk of complications or further damage.

Surgeons prefer to use external fixation because it allows them to achieve correction percutaneously. This means that they can correct the issue without making large incisions or invasive procedures. This method is less invasive and can lead to faster recovery times for the patient. Additionally, external fixation is often cheaper than other options such as plating or screws, making it a more cost-effective choice. It is not mentioned in the options that it reimburses more than other options, so this cannot be considered as a reason for surgeons to prefer external fixation.

Olive wires are used for several reasons. Firstly, they help keep bone segments centered in the ring, ensuring proper alignment. Additionally, olive wires provide the ability to compress internally, which is beneficial for stabilizing the bone fragments. Furthermore, they minimize movement as the bone cannot slide over the wire, promoting stability. Lastly, olive wires provide opposing forces for alignment, aiding in the proper positioning of the bone segments. Therefore, all of the given reasons are valid explanations for why olive wires are used.

The correct answer is 140, 160, and 180. This is indicated by the third option in the given choices.

A surgeon would use a static frame over a dynamic frame when treating Charcot because gradual correction using a dynamic frame would require too much time. This suggests that using a static frame allows for a quicker and more efficient treatment process.

The pathophysiology of Charcot neuroarthropathy is still unknown. This means that the exact underlying mechanisms and processes that lead to the development of this condition are not yet fully understood. Despite extensive research and observations, there is no consensus on the specific pathophysiological factors involved. Therefore, the correct answer is "Still unknown."

Pinzur used circular external fixation in 2006 to maintain alignment of deformity correction in high-risk, obese patients with Charcot neuroarthropathy. This technique was likely chosen due to its effectiveness in providing stability and support to the affected area, reducing the risk of further deformity or complications. The use of circular external fixation in this specific patient population demonstrates Pinzur's innovative approach to addressing the challenges associated with Charcot neuroarthropathy in obese individuals.
