Can all joints take a positive lateral position? Please give detailed examples.

All joints can be photographed in the forward position (technically), but from the doctor's point of view, some joints or bones are not recommended to be photographed sideways, and some joints or bones are meaningless, which wastes the patient's money (for example, there are many bones, and the imaging effect of bones taken sideways is not obvious).

Example 1, metacarpal bone: Generally, the chest radiograph is oblique. If you take a lateral metacarpal film, basically no one can see the bone structure clearly;

Example 2: Foot bone: Normal fault or oblique fault is generally taken, and the principle is the same as metacarpal bone.

Example 3, Thoracocostal joint: It is common to take a positive film or an oblique film. There are ribs on both sides of the chest, so it is impossible to see the structure of the sternoclavicular joint clearly on the lateral radiograph;

Example 4: Hip joint: Generally, the anteroposterior (pelvic anteroposterior) film is taken, while the lateral film is meaningless. If necessary, you can take a slant film;

Example 5, Knee joint: The common X-ray film is anteroposterior position. If necessary, take oblique or axial photos of the knee joint.
