Patient: My current symptoms: my right wrist moves normally (a little pain on the ulnar side after rotation, probably because the injury is not very strong) There is no obvious pressure point on the wrist in the “frontal” part of Figure 1, which is framed in red, and sometimes there is a sound like a card when I press slightly. I don’t know if this is the case or if the ligaments are injured, can you diagnose the problem based on my condition? What is the treatment method? Beijing Shunyi Hospital orthopedic department Yang Chenggang: general ulnar pain of the wrist first consider PFC injury triangular cartilage disc injury, but PFC in the X-ray and CT are not visible, MRI examination is recommended, wrist arthroscopy is the gold standard of diagnosis. The ulnar lateral squeeze test and rotation test in physical examination are helpful for diagnosis. Early acute injury can be treated conservatively for 3 months, mainly by local braking, application of protective brace to limit the activity, and also local physical therapy. If after 3 months there are still symptoms or ulnar instability, arthroscopic wrist repair is recommended.
