If there is a secondary displacement of the left finger fracture after surgery, then either manipulative repositioning or surgical correction can be considered. 1. Manipulation: Manipulation refers to the unarmed restoration of the fracture to its normal position, thus promoting healing of the fracture. Manipulation is currently used for mildly displaced fractures or when the fracture is stable. Manipulation can avoid the need for surgery, thus reducing pain and risk, and can be used in conjunction with external fixation devices to ensure the stability of the fracture. 2. Surgical fixation: Surgical fixation is recommended after secondary displacement in patients who were first treated with surgical internal fixation or who are severely displaced. By opening the fracture site and carrying out secondary internal fixation, the fracture is directly repositioned and stabilized with titanium plates and other internal fixation devices. After the fracture, try to avoid excessive force on the fracture site, and try to ensure the stability of the bone to avoid displacement and other adverse symptoms. At the same time, self-reduction or unauthorized finger fixation is not recommended, and timely medical treatment should be sought.
